6 < REUT > REUT REUTS REUTS [7T: RE7R01] recaution for Supplemental Restraint System (SRS) "R G" and "SET ELT RE-TESER" D: The Supplemental Restraint System such as R G and SET ELT RE-TESER, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. nformation necessary to service the system safely is included in the SRS R G and SET ELT of this Service anual. WRG: To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that would result in air bag inflation, all maintenance must be performed by an authorized SS/T dealer. mproper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. or removal of Spiral able and ir ag odule, see the SRS R G. Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service anual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. REUTS WE USG WER TLS (R R ELETR) D ERS WRG: When working near the ir ag Diagnosis Sensor Unit or other ir ag System sensors with the ignition or engine running, D T use air or electric power tools or strike near the sensor(s) with a hammer. eavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. When using air or electric power tools or hammers, always switch the ignition, disconnect the battery, and wait at least 3 minutes before performing any service. General recautions Turn ignition switch and disconnect the battery cable from the negative terminal before connecting or disconnecting the /T assembly connector. ecause battery voltage is applied to T even if ignition switch is turned. D: SE289 erform DT (Diagnostic Trouble ode) RT REDURE after performing each TRULE DGSS. f the repair is completed DT should not be displayed in the DT RT REDURE. lways use the specified brand of T. Refer to -10, "luids and Lubricants". Use lint-free paper not cloth rags during work. Dispose of the waste oil using the methods prescribed by law, ordinance, etc. after replacing the T. efore proceeding with disassembly, thoroughly clean the outside of the transmission. t is important to prevent the internal parts from becoming contaminated by dirt or other foreign matter. T-6 SE217U

7 < REUT > REUTS [7T: RE7R01] Disassembly should be done in a clean work area. Use lint-free paper or towels for wiping parts clean. ommon shop rags can leave fibers that could interfere with the operation of the transmission. lace disassembled parts in order for easier and proper assembly. ll parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or reassembly. Gaskets, seals and -rings should be replaced any time the /T is disassembled. t is very important to perform functional tests whenever they are indicated. The valve body contains precision parts and requires extreme care when parts are removed and serviced. lace disassembled valve body parts in order for easier and proper assembly. are will also prevent springs and small parts from becoming scattered or lost. roperly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight. efore assembly, apply a coat of recommended T to all parts. pply petroleum jelly to protect -rings and seals, or hold bearings and washers in place during assembly. ever use grease. Extreme care should be taken to avoid damage to -rings, seals and gaskets when assembling. When the /T drain plug is removed, only some of the T is drained. ld T will remain in torque converter and T cooling system. lways follow the procedures under hanging when changing T. Refer to T-94, "hanging". ccasionally, the parking gear may be locked with the torque insufficiently released, when stopping the vehicle by shifting the selector lever from D or R to position with the brake pedal depressed. n this case, the shock with a thud caused by the abrupt release of torque may occur when shifting the selector lever from position to other positions. owever, this symptom is not a malfunction which results in the damage of parts. Service otice or recaution D: T LER SERVE f T contains frictional material (clutches, bands, etc.), or if an /T is repaired, overhauled, or replaced, inspect and clean the /T fluid cooler mounted in the radiator or replace the radiator. lush cooler lines using cleaning solvent and compressed air after repair. or /T fluid cooler cleaning procedure, refer to T-97, "leaning". or radiator replacement, refer to -13, "Exploded View".

When engine is started while engine and /T are cold, engine coolant temperature rises more quickly than /T fluid temperature. /T fluid warmer is provided with two circuits for T and engine coolant respectively so that warmed engine coolant warms T quickly. This helps shorten /T warming up time, improving fuel economy. cooling effect is obtained when /T fluid temperature is high. JSD1803G JSD1811ZZ /T fluid cooler (with bypass valve) /T fluid cooler (1) is installed in the front of radiator (2) and condenser (3). /T fluid cooler is provided with a bypass valve that controls T flow. ypass valve operates by thermo wax and a return spring. ypass valve fully opens when /T fluid temperature is approximately 90 (194 ) and fully closes when /T fluid temperature is approximately 100 (212 ).
