NOTE: Indicates special information to make maintenance easier or instructions clearer. This service manual is intended for authorized Suzuki dealers and qualified service technicians only. Inexperienced technicians or technicians without the proper tools and equipment may not be able to properly perform the services described in this manual. Improper repair may result in injury to the technician and may render the vehicle unsafe for the driver and passengers. WARNING ! For vehicles equipped with a Supplemental Restraint (Air Bag) System: • Service on and around the air bag system components or wiring must be performed only by an authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under “General Description” in air bag system section in order to confirm whether you are performing service on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser- vice Precautions” under “On-Vehicle Service” in air bag system section before performing service on or around the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional activation of the system or could render the system inoperative. Either of these two conditions may result in severe injury. • If the air bag system and another vehicle system both need repair, Suzuki recommends that the air bag system be repaired first, to help avoid unintended air bag system activation. • Do not modify the steering wheel, instrument panel or any other air bag system component on or around air bag system components or wiring. Modifications can adversely affect air bag system performance and lead to injury. • If the vehicle will be exposed to temperatures over 93 °C (200 °F), for example, during a paint baking process, remove the air bag system components, that is air bag (inflator) modules, SDM and/or seat belt with pretensioner, beforehand to avoid component damage or unintended activation. WARNING !

00-1 Precautions: Precautions Precautions Precautions for Vehicles Equipped with a Supplemental Restraint (Air Bag) System S5JB0A0000001 WARNING ! • The configuration of air bag system parts are as shown in the figure. When it is necessary to service (remove, reinstall and inspect) these parts, be sure to follow procedures described in “Precautions on Service and Diagnosis of Air Bag System in Section 8B”. Failure to follow proper procedures could result in possible air bag system activation, personal injury, damage to parts or air bag system being unable to activate when necessary. • If the air bag system and another vehicle system both need repair, SUZUKI recommends that the air bag system be repaired first, to help avoid unintended air bag system activation. • Do not modify the steering wheel, dashboard, or any other air bag system components. Modifications can adversely affect air bag system performance and lead to injury. • If the vehicle will be exposed to temperatures over 93 °C (200 °F) (for example, during a paint baking process), remove the air bag system components beforehand to avoid component damage or unintended air bag system activation. 1.

Precautions: 00-2 Diagnosis • When troubleshooting air bag system, be sure to follow “Air Bag Diagnostic System Check in Section 8B”. Bypassing these procedures may result in extended diagnostic time, incorrect diagnosis, and incorrect parts replacement. • Never use electrical test equipment other than that specified. WARNING ! Never attempt to measure the resistance of the air bag (inflator) modules (driver, passenger, side and curtain) and seat belt pretensioners (driver and passenger). It is very dangerous as the electric current from the tester may deploy the air bag or activate the pretensioners. Servicing and Handling WARNING ! Many of service procedures require disconnection of “A/B” fuse and all air bag (inflator) module(s) from system circuit to avoid an accidental deployment. Driver, Passenger, Side and Curtain Air Bag (Inflator) Modules • For handling and storage of a live air bag (inflator) module, select a place where the ambient temperature below 65 °C (150 °F), without high humidity and away from electric noise. • When carrying a live air bag (inflator) module, make sure the bag opening is pointed away from you. In case of an accidental deployment, the bag will then deploy with minimal chance of injury. Never carry the air bag (inflator) module by the wires or connector on the underside of the module. When placing a live air bag (inflator) module on a bench or other surface, always face the bag up, away from the surface. This is necessary so that a free space is provided to allow the air bag to expand in the unlikely event of accidental deployment. Otherwise, personal injury may result. I5JB0A000001-02 [A]: Always carry air bag (inflator) module with trim cover (air bag opening) away from body. [B]: Always place air bag (inflator) module on workbench with trim cover (air bag opening) up, away from loose objects. [A] [B] I5JB0A000002-02

00-3 Precautions: • Never dispose of live (undeployed) air bag (inflator) modules (driver, passenger, side and curtain). If disposal is necessary, be sure to deploy them according to deployment procedures described in “Air Bag (Inflator) Module and Seat Belt Pretensioner Disposal in Section 8B”. • The air bag (inflator) module immediately after deployment is very hot. Wait for at least half an hour to cool it off before proceeding the work. • After an air bag (inflator) module has been deployed, the surface of the air bag may contain a powdery residue. This powder consists primarily of cornstarch (used to lubricate the bag as it inflates) and by- products of the chemical reaction. As with many service procedures, gloves and safety glasses should be worn. WARNING ! SDM • During service procedures, be very careful when handling a Sensing and Diagnostic Module (SDM). • Never strike or jar the SDM. • Never power up the air bag system when the SDM is not rigidly attached to the vehicle. All SDM and mounting bracket fasteners must be carefully torqued and the arrow must be pointing toward the front of the vehicle to ensure proper operation of the air bag system. The SDM could be activated when powered while not rigidly attached to the vehicle which could cause deployment and result in personal injury. WARNING ! Driver and Passenger Seat Belt Pretensioners • For handling and storage of a live seat belt pretensioner, select a place where the ambient temperature below 65 °C (150 °F), without high humidity and away from electric noise. • Never carry seat belt pretensioner by wire or connector of pretensioner. When placing a live seat belt pretensioner on the workbench or some place like that, be sure not to lay it with its exhaust hole (1) provided side facing down. It is also prohibited to put something on its face with an exhaust hole or to put a seat belt pretensioner on top of another. Otherwise, personal injury may result. • Never dispose of live (inactivated) seat belt pretensioners (drive and passenger). If disposal is necessary, be sure to activate them according to activation procedures described in “Air Bag (Inflator) Module and Seat Belt Pretensioner Disposal in Section 8B” before disposal. • The seat belt pretensioner immediately after activation is very hot. Wait for at least half an hour to cool it off before proceeding the work. • With many service procedures, gloves and safety glasses should be worn to prevent any possible irritation of the skin or eyes. 1 I4JA01822118-01
