1 Tire Pressure Monitoring System (TPMS) Applicable only in the United States Introduction In this section you ll find information about: Indicator light (telltale) Indicator light (telltale) Tire Pressure Monitoring System (TPMS) Tire Pressure Monitoring System (TPMS) The Tire Pressure Monitoring System (TPMS) uses a pressure sensor in each wheel. Signals from the sensors are transmitted to the TPMS. The TPMS checks the tire pressure of all 4 tires while you are driving and warns if there is a loss of pressure while the vehicle is moving. Pressure loss that is 25% or more of the benchmark value programmed into the system is signaled by the indicator light (telltale), by acoustic warnings, and by text messages in the instrument cluster display.

2 WARNING Incorrect tire pressures and/or underinflation can cause sudden tire failure, loss of control, collision, serious personal injury or even death. When the warning symbol appears in the instrument cluster, stop and inspect the tires. Incorrect tire pressure and/or underinflation can cause increased tire wear and can affect the handling of the vehicle and stopping ability. Incorrect tire pressures and/or underinflation can also lead to sudden tire failure, including a blowout and sudden deflation, causing loss of vehicle control. The driver is responsible for the correct tire pressures for all tires on the vehicle. The recommended tire pressure values are listed on a sticker inside the driver door. The TPMS can only work correctly when all tires on the vehicle are filled to the correct cold tire inflation pressure specified for the tires installed on the vehicle. Using incorrect tire pressure values can cause accidents or other damage. Always inflate the tires to the correct specified cold tire pressure values for the tires installed on the vehicle. Always maintain correct cold tire inflation pressure so that TPMS can do its job. Always inflate tires to the recommended and correct tire pressure before driving off. Driving with underinflated tires causes them to flex (bend) more, letting them get too hot, resulting in tread separation, sudden tire failure, and loss of control. Excessive speed and/overloading can cause heat build-up, sudden tire failure, and loss of control. If the tire pressure is too low or too high, the tires will wear prematurely and the vehicle will not handle well. If the tire is not flat and you do not have to change a wheel immediately, drive carefully and at reduced speed to the nearest service station to check the tire pressure and add air as required. When replacing tires or wheel rims on vehicles equipped with TPMS always read and heed the information and all WARNINGS regarding, Tires and wheels. NOTICE The wheel electronics are attached to special aluminum valves on the wheels. These valves are screwed on rigidly. Never bend the valves into position when checking and adjusting tire pressure. Missing valve stem caps can cause damage to the valves as well as to the TPMS sensors. To help prevent damage, always use valve stem caps like those originally installed at the factory. The caps must be screwed on tightly. Do not use metal valve stem caps. Do not use comfort valve caps. They do not seal properly and can damage the sensors. When replacing or rotating tires, make certain the valves and sensors are not damaged. The aluminum valves that are installed should be replaced after about 6 years of use because of aging in the rubber seals. The valves can be replaced when a tire is changed. Do not reuse aluminum valves after they are removed. They must be replaced. The tire pressure sensor can be reused. When replacing the valve cores, use only nickel-plated replacement cores. The batteries in the wheel electronics last up to 10 years. It is not possible to replace the batteries. The entire device must be replaced. Underinflation increases fuel consumption and tire wear.

3 Dispose of the wheel electronics and the old batteries in an environmentally responsible manner. Batteries of the type used in the wheel electronics may contain Perchlorate Material. Special handling may apply. See Obey all applicable legal requirements regarding proper disposal. Do not rely only on the Tire Pressure Monitoring System. Check your tires regularly to make sure they are properly inflated and have no signs of damage, such as punctures, cuts, cracks, and blisters. Remove any objects that become embedded in the tire tread but have not penetrated into the body of tire itself. The Tire Pressure Monitoring System checks for the factory-recommended inflation pressure, as shown on the label inside the driver door For replacement tires that require a different inflation pressure, the TPMS must be adjusted to the new pressure specification by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. Only one value can be entered for each tire; see the tire inflation pressure label on the driver door pillar To help prevent damage to the sensor and valve, do not put excessive force on the valve when checking the tire pressure. Do not try to bend the valve. If sensors have to be replaced, have the valves changed at the same time. The tire valve gaskets must be replaced whenever a tire is mounted on the rim. Your authorized Volkswagen dealer or authorized Volkswagen Service Facility has a valve seal and gasket kit for this purpose. Always make sure that a valve seal and gasket kit is also used whenever a sensor is replaced. If you have to adjust the tire pressure on a warm tire, fill the tire with psi (20-30 kpa) more than the pressure specified on the tire pressure label. When the TPMS determines that the air pressure in at least one tire is too low, carefully check the pressure in all 4 tires with an accurate tire pressure gauge. Low tire pressure usually cannot be determined by looking at the tire. This is especially true of low-profile tires. A Declaration of Compliance with the United States FCC and Industry Canada regulations is found in the Consumer Information section of this Manual There may be differences between the pressure readings from a tire pressure gauge and the pressures registered by the Tire Pressure Monitoring System. The electronic TPMS is more accurate. If you have work done on your wheels or tires, inform the workshop that the vehicle is equipped with a Tire Pressure Monitoring System that has sensors in the wheels. Applicable only in Canada Introduction In this section you ll find information about: Indicator light (telltale) Indicator light (telltale) Tire Pressure Monitoring System (TPMS) Tire Pressure Monitoring System (TPMS)

4 Your vehicle's Tire Pressure Monitoring System (TPMS) uses the Anti-lock Brake System (ABS) sensors to indirectly check the tire pressure of all 4 tires while you are driving. The sensors monitor the tread circumference (rolling circumference) and vibration characteristics of the individual tires. TPMS warns if there is a significant loss of pressure in one or more tires while the vehicle is moving. Pressure loss is signaled by the indicator light Ç (described below) as well as by text warnings in the instrument cluster display if your vehicle has this display (Multi-Function Indicator- MFI). The original benchmark pressure is the recommended maximum load cold tire inflation pressure for the tires that come with your vehicle. This pressure is listed on the tire pressure label on the driver door jamb. After adjusting the tire pressures in all 4 tires, you must confirm and store the new cold inflation pressures using the Settings menu in the instrument cluster, which changes the benchmark pressure to match the current pressure of the tires on your vehicle. Recalibrating the TPMS to reset the benchmark cold tire inflation pressure is explained below More information: Volkswagen Information System Transporting Braking, stopping and parking Exterior care and cleaning Tires and wheels Parts, accessories, repairs and modifications Consumer information

5 WARNING Incorrect tire pressures and/or underinflation can cause sudden tire failure, loss of control, collision, serious personal injury or even death. When the warning symbol appears in the instrument cluster, stop and inspect the tires. Incorrect tire pressure and/or underinflation can cause increased tire wear and can affect the handling of the vehicle and stopping ability. Incorrect tire pressures and/or underinflation can also lead to sudden tire failure, including a blowout and sudden deflation, causing loss of vehicle control. The driver is responsible for the correct tire pressures for all tires on the vehicle. The recommended tire pressure values are listed on a sticker inside the driver door 272. The TPMS can only work correctly when all tires on the vehicle are filled to the correct cold tire inflation pressure. Using incorrect tire pressure values can cause accidents or other damage. Always inflate the tires to the correct specified cold tire pressure values for the tires installed on the vehicle. Always maintain correct cold tire inflation pressure so that TPMS can do its job. Always inflate tires to the recommended and correct tire pressure before driving off. Driving with underinflated tires causes them to flex (bend) more, letting them get too hot, resulting in tread separation, sudden tire failure, and loss of control. Excessive speed and/overloading can cause heat build-up, sudden tire failure and loss of control. If the tire pressure is too low or too high, the tires will wear prematurely and the vehicle will not handle well. If the tire is not flat and you do not have to change a wheel immediately, drive carefully and at reduced speed to the nearest service station to check the tire pressure and add air as required. When replacing tires or wheel rims on vehicles equipped with TPMS always read and heed the information and all WARNINGS regarding, Tires and wheels. The Tire Pressure Monitoring System must be recalibrated whenever you remove and remount or change any wheel or tire on the vehicle, even if the reinstalled or replacement wheels and tires are identical to those that were removed and even if the tire pressure does not change. WARNING Improper recalibration can cause the TPMS to give false warnings or to give no warning despite dangerously low tire pressure. Underinflation increases fuel consumption and tire wear. Do not rely solely on the Tire Pressure Monitoring System. Check your tires regularly to make sure they are properly inflated and have no signs of damage, such as punctures, cuts, cracks, and blisters. Remove any objects that become embedded in the tire tread but have not penetrated into the body of tire itself. When you take delivery of the vehicle, the Tire Pressure Monitoring System is calibrated for the factory-recommended cold tire inflation pressure for the tires on your vehicle, as shown on the label inside the driver door.

6 The system must be recalibrated whenever you remove and remount or change any wheel or tire on the vehicle, even if the reinstalled or replacement wheels and tires are identical to those that were removed and even if the tire pressure does not change. If you have to adjust the tire pressure on a warm tire, fill the tire with psi (20-30 kpa) more than the pressure specified on the tire pressure label inside the driver door 272. If the TPMS determines that the air pressure in at least one tire is too low, carefully check the pressure in all 4 tires with an accurate tire pressure gauge. Low tire pressure usually cannot be determined by looking at the tire. This is especially true of low-profile tires. If you have work done on your wheels or tires, inform the workshop that the vehicle is equipped with a Tire Pressure Monitoring System (TPMS). New tires may expand slightly the first time they are driven at high speeds, which can trigger a tire pressure warning. Remember that tire pressure can only be properly measured when the tire is cold. Only replace old tires with tires that have been approved by Volkswagen for your vehicle type. Applicable only in the United States Indicator light (telltale) Please first read and note the introductory information and heed the WARNINGS 222. Lights up Display text Possible cause or meaning FLAT TIRE TIRE PRESSURE TOO LOW Rapid loss of pressure in one or more tires. At least one tire has a pressure below 20.3 psi (1.4 bar) or a loss of tire pressure greater than 2.9 psi/min (0.2 bar/min). Critical loss of pressure in at least one tire with the pressure more than 7.25 psi (0.5 bar) below the specified value. Proper response Stop! Reduce speed immediately! Stop the vehicle as soon as it is safe to do so. Avoid fast cornering and hard braking! Check all tires for external damage and embedded objects. Check the inflation pressure of all 4 tires. If you are sure it is not necessary to change a tire right away, drive at reduced speed to the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility. Immediately check the tire inflation pressure of all tires. If you are sure it is not necessary to change a tire right away, drive at reduced speed to the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility.

7 Flashes Display text Possible cause or meaning Ç There is a malfunction (Intermittently while driving.) between a sensor and the system. The function can be temporarily disrupted by interference from transmitters in the vicinity of the vehicle working in the same frequency range such as radio equipment, remote controls or children's toys. There is a system malfunction if the indicator light flashes for about 65 seconds and then stays on continuously. Proper response Switch the source of interference off. If the tire pressure is correct but the indicator light stays on or keeps flashing after you switch the ignition off and on again, have an authorized Volkswagen dealer or an authorized Volkswagen Service Facility check the system. When the ignition is switched on, several warning and indicator lights come on briefly for a function check. They go out after a few seconds.

8 WARNING Incorrect tire pressures and/or underinflation can cause sudden tire failure, loss of control, collision, serious personal injury, or even death. When the warning symbol Ç appears in the instrument cluster, stop the vehicle as soon as it is safe to do so and inspect all tires. Incorrect tire pressure and/or underinflation can cause increased tire wear and can affect the handling of the vehicle and its stopping ability. Incorrect tire pressure and/or underinflation can also lead to sudden tire failure, including a blowout and sudden deflation, causing loss of vehicle control. The driver is responsible for the correct tire pressures for all tires on the vehicle. The recommended tire pressure values are listed on a sticker inside the driver's door The TPMS can only work correctly when all tires on the vehicle are filled to the correct cold tire inflation pressure. Always maintain the correct cold tire inflation pressure so that TPMS can do its job. Using incorrect tire pressure values can cause accidents or other damage. Check the pressure in all 4 tires when the tires are still cold. Never reduce air pressure in warm tires to match cold tire inflation pressure. Always inflate the tires to the correct specified cold tire pressure values for the tires installed of the vehicle; see the tire inflation pressure label on the driver door jamb. Always inflate tires to the recommended and correct tire pressure before driving off. Driving with underinflated tires causes them to flex (bend) more, letting them get too hot, which can result in tread separation, sudden tire failure, and loss of control. Excessive speed and/or overloading can cause heat build-up, sudden tire failure, and loss of control. If the tire pressure is too low or too high, the tires will wear prematurely and the vehicle will not handle well.

WARNING Failure to heed warning lights and instrument cluster text messages can cause the vehicle to break down in traffic and result in a collision and serious personal injury. Never ignore warning lights or text WARNINGS. Always stop the vehicle as soon as it is safe to do so. NOTICE Failure to heed warning lights or text WARNINGS can result in vehicle damage. Applicable only in Canada Indicator light (telltale) Please first read and note the introductory information and heed the WARNINGS

9 Lights up Possible cause or meaning Lights up and a chime may also sound. The inflation pressure of one or more tires is significantly lower than the benchmark pressure set by the driver or a tire has structural damage. Depending on vehicle equipment, a text message may also appear in the instrument cluster display. Proper response Stop safely as soon as possible! Reduce speed immediately! Avoid fast cornering and hard braking! Check the condition and inflation pressure of all tires. Have damaged tires replaced. Flashes Possible cause or meaning Flashes for about 1 minute and then stays on: System malfunction. Proper response Check and, if necessary, adjust the tire inflation pressure in all 4 tires. If the tire pressure is correct, switch the ignition off and back on. If the indicator light flashes again and then stays on or does not go out after checking and adjusting the air pressure in all 4 tires and you cannot calibrate the TPMS, take the vehicle to an authorized Volkswagen dealer or an authorized Volkswagen Service Facility. Have the system checked. When the ignition is switched on, several warning and indicator lights come on briefly for a function check. They go out after a few seconds.

When replacing tires or wheel rims on vehicles equipped with TPMS, always read and heed the information and all WARNINGS in the section 267, Tires and wheels. The Tire Pressure Monitoring System must be recalibrated whenever you remove and remount or change any wheel or tire on the vehicle, even if the reinstalled or replacement wheels and tires are identical to those that were removed and even if the tire pressure does not change WARNING Improper recalibration can cause the TPMS to give false warnings or to give no warning despite dangerously low tire pressure WARNING Failure to heed warning lights and instrument cluster text messages can cause the vehicle to break down in traffic and result in a collision and serious personal injury. Never ignore warning lights or text WARNINGS. Always stop the vehicle as soon as it is safe to do so.

11 NOTICE Failure to heed warning lights or text WARNINGS can result in vehicle damage. Driving for a longer period of time on rough roads or with a dynamic and sporty style can make the TPMS system temporarily unavailable. The indicator light will come on, signaling a malfunction, but will go out again once the road condition or driving style changes. Applicable only in the United States Tire Pressure Monitoring System (TPMS) Fig. 135 Display screen in the instrument cluster: Current tire pressures in psi. Please first read and note the introductory information and heed the WARNINGS The Tire Pressure Monitoring System uses a pressure sensor in each wheel. Signals from the sensors are transmitted to the TPMS. The TPMS checks the tire pressure of all 4 tires while you are driving and warns if there is a loss of pressure while the vehicle is moving. Pressure loss that is 25% or more of the benchmark value programmed into the system is signaled by the indicator light (telltale) described above, by acoustic warnings, and by text messages in the instrument cluster display. If you mount tires of a different size than the factory installed tires, an authorized Volkswagen dealer or an authorized Volkswagen Service Facility can adjust the benchmark TPMS tire pressure to match the new tires. Without this adjustment, TPMS may not work correctly or at all. The tire pressure recommended for the tires originally installed on the vehicle is on a sticker on the driver door jamb Display in the instrument cluster The display in the instrument cluster shows the vehicle with the actual and benchmark tire pressures of all 4 road wheels fig. 135 Tire pressure display screen Meaning (1) Tire pressure warning, left rear tire. (2) Current tire pressure, front left tire.

12 Tire pressure display screen Meaning (3) Benchmark pressure, front tires (4) Current tire pressure, front right tire. (5) No data received, right rear tire. (6) Benchmark pressure, rear tires If the tire pressure is too low, the relevant tires and the respective readings are highlighted in yellow. Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a Tire Pressure Monitoring System (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. Spare wheel or compact spare wheel The spare wheel or compact spare wheel has no tire pressure sensor. When the spare or compact spare wheel is mounted on the vehicle, the Tire Pressure Monitoring System (TPMS) indicator light will flash in the instrument cluster display. The TPMS continues to monitor the other 3 wheels. Tire storage If the tires do not move for an extended period of time, the sensors will not transmit tire pressures to the system. This saves sensor battery life. When the ignition is switched on, the sensors transmit signals to the Tire Pressure Monitoring System.

13 WARNING Incorrect tire pressure can cause sudden tire failure, loss of vehicle control and serious personal injury. Always check and correct air pressure in all 4 tires, particularly after changing, exchanging, or repairing tires. After that, always make sure that all 4 tires are inflated to the correct tire pressure for the tires installed on the vehicle. See the tire pressure label and the Owner's Literature for recommended cold tire inflation pressure and other important information. When replacing tires or wheel rims on vehicles equipped with TPMS, always read and heed all of the information and WARNINGS. NOTICE The wheel electronics are attached to special aluminum valves on the wheels. These valves are screwed on rigidly. Never bend the valves into position when checking and adjusting tire pressure. Missing tire air valve caps could result in damage to the valves, as well as to the sensors on the Tire Pressure Monitoring System. Therefore, make sure your valve caps conform to the specifications of those originally installed on the vehicle and that they are always tightly and properly screwed on to the valves. Do not use metallic valve caps Do not use comfort valve caps, as these do not seal properly and could therefore cause damage to the sensors. When changing or rotating the tires, be careful not to damage the valves or sensors. The aluminum valves that are installed should be replaced after about 6 years of use because of aging in the rubber seals. The valves can be replaced when a tire is changed. Do not reuse aluminum valves after they are removed. They must be replaced. The tire pressure sensor can be reused. Applicable only in Canada Tire Pressure Monitoring System (TPMS) Please first read and note the introductory information and heed the WARNINGS. Your vehicle's Tire Pressure Monitoring System (TPMS) indirectly checks the tire pressure of all 4 tires while you are driving by using the Anti-lock Brake System (ABS) sensors to monitor the tread circumference (rolling circumference) and vibration characteristics of the individual tires. The tread circumference of a tire can change: If a tire's inflation pressure is too low. If the tire's tread is damaged or the tire is structurally damaged. If one side of the vehicle is more heavily loaded than the other. If there is more weight on one axle than the other (such as when towing a trailer). If a compact spare wheel has been mounted. If a wheel was replaced on each axle. If a tire was changed. If the tire pressure was changed, or wheels were rotated or replaced, but the TPMS was not reset. If there are snow chains on the tires. Using snow chains can cause the system to give false warnings because snow chains increase tire circumference.

14 The Tire Pressure Monitoring System may not react at first or may not react at all when you are driving in a sporty manner, or on snow-covered or unpaved roads, when you are driving with snow chains, or in certain other situations. A change in the tread circumference of a tire is signaled by the Tire Pressure Monitoring System indicator in the instrument cluster (telltale). The tire pressure recommended for the tires originally installed on the vehicle is on a sticker on the driver door jamb Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a Tire Pressure Monitoring System (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle s handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver s responsibility to maintain correct tire pressure, even if underinflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. Resetting and recalibrating the benchmark tire pressure Resetting the tire pressures in the Multi-function Display (MFI) resets the benchmark tire pressure used by the TPMS to the current tire pressure in the tires based on the circumference of the tires. To reset the reference tire pressure, switch on the ignition. In the MFI, navigate to the Settings menu and select Tire pressure. Store and confirm the new tire pressures. The recalibration must be performed each time the tire pressure in one or more tires has been adjusted or after one or more tires has been changed, exchanged, or repaired. The new tire pressures are stored in the system only after at least 20 minutes of normal driving. If you have reset the benchmark tire pressure when your tires do not have the correct tire pressure, this will prevent the TPMS from working properly. It may then give false warnings or may not give any warning even if the tire pressure is too low. For this reason, it is vital to make certain that all 4 tires are inflated to the correct pressure when they are cold, before calibrating the system. Cold tire tires are tires that have not been driven more than a couple of miles (kilometers) at low speed within the last 3 hours. Recalibrate the system to reset the benchmark TPMS pressure in the following situations: After installing tires on your vehicle that have recommended cold tire inflation pressures that are different from the tires that were taken off. After any tire on your vehicle is removed and then remounted, even if the same tire and wheel rim that were taken off are reinstalled (for instance, after repair).

15 After any tire on your vehicle is changed and replaced by another tire, even if the replacement tire is the same type and is inflated to the same pressure as the tire it replaced. After adjusting the tire pressure of any tire on the vehicle to its correct cold tire inflation pressure, either by putting air in one or more tires or by letting air out. Do this even though air was only added (or let out) to bring the tire to the inflation pressure it should have had all along. After rotating the front and rear wheels After mounting the compact spare tire. WARNING Incorrect recalibration can cause the TPMS to give false warnings or to give no warning despite dangerously low tire pressure. Make certain the tire inflation pressure of all tires is correct before resetting the system. WARNING Incorrect tire pressure can cause sudden tire failure, loss of vehicle control and serious personal injury. Always check and correct air pressure in all 4 tires, particularly after changing, exchanging, or repairing tires. After that, always make sure that all 4 tires are inflated to the correct tire pressure for the tires installed on the vehicle. Then reset the system so that it can monitor the correct tire pressure. See the tire pressure label and the Owner's Literature for recommended cold tire inflation pressure and other important information. When replacing tires or wheel rims, always read and heed all of the information and WARNINGS The Tire Pressure Monitoring System must be recalibrated whenever you remove and remount or change any wheel or tire on the vehicle, even if the reinstalled or replacement wheels and tires are identical to those that were removed and even if the tire pressure does not change. The Tire Pressure Monitoring System stops working if there is an ESC/ABS malfunction. After a low tire pressure warning, the vehicle must stand and must not be driven for at least one minute before the new benchmark tire pressures can be stored.
