2 SERVE RT REUTS REUTS recaution for Supplemental Restraint System (SRS) "R " and "SET ET RE-TESER" : The Supplemental Restraint System such as R and SET ET 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 and S section of this Service anual. WR: To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which 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 section. o 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 US WER TS (R R EETR) ERS WR: When working near the irbag iagnosis Sensor Unit or other irbag System sensors with the gnition or engine running, 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 gnition, disconnect the battery, and wait at least 3 minutes before performing any service. recaution ecessary for Steering Wheel Rotation fter attery isconnect SU-2 : TE: This rocedure is applied only to models with ntelligent ey system and TS (SS T-TET SYS- TE). Remove and install all control units after disconnecting both battery cables with the ignition knob in the position. lways use SUT- to perform self-diagnosis as a part of each function inspection after finishing work. f T is detected, perform trouble diagnosis according to self-diagnostic results. or models equipped with the ntelligent ey system and TS, an electrically controlled steering lock mechanism is adopted on the key cylinder. or this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and steering wheel rotation will become impossible. f steering wheel rotation is required when battery power is interrupted, follow the procedure below before starting the repair operation. ERT REURE 1. onnect both battery cables. TE: Supply power using jumper cables if battery is discharged. 2. Use the ntelligent ey or mechanical key to turn the ignition switch to the position. t this time, the steering lock will be released. 3. isconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated. 4. erform the necessary repair operation.

3 REUTS 5. When the repair work is completed, return the ignition switch to the position before connecting the battery cables. (t this time, the steering lock mechanism will engage.) 6. erform a self-diagnosis check of all control units using SUT-. recaution for rocedure without owl Top over When performing the procedure after removing cowl top cover, cover the lower end of windshield. : SU autions WE0178E : When installing rubber bushings, the final tightening must be carried out under unladen conditions with tires on ground. il might shorten the life of rubber bushings. e sure to wipe off any spilled oil. - Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and mats are in designated positions. fter servicing suspension parts, be sure to check wheel alignment. Self-lock nuts are not reusable. lways use new ones when installing. SU-3
