2 < SRV RT > SRV RT RUTS RUTS recaution for Supplemental Restraint System (SRS) "R B" and "ST BT R-TSR" : The Supplemental Restraint System such as R B and ST BT R-TSR, 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 SB 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 Bag 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. -2

Be sure to work in a well ventilated area and have a 2 fire extinguisher. o not smoke while working on the fuel system. eep open flames and sparks away from the work area. UT: Before removing fuel line parts, carry out the following procedures: - ut drained fuel in an explosion-proof container and put the lid on securely. eep the container in safe area. - Release fuel pressure from the fuel lines. Refer to -77, "uel ressure heck". - isconnect the battery ground cable. lways replace -rings and clamps with new ones. o not kink or twist tubes when they are being installed. o not tighten hose clamps excessively to avoid damaging hoses. Tighten high-pressure rubber hose clamp so that clamp end is 3 mm (0.12 in) from hose end. Tightening torque specifications are the same for all rubber hose clamps. nsure that screw does not contact adjacent parts
