Precautions For Vehicles Equipped With Supplemental Restraint (Air Bag) System

Precautions For Vehicles Equipped With Supplemental Restraint (Air Bag) System

WARNING:
- The configuration of air bag system parts are as shown in figure. When it is necessary to service (remove, reinstall and inspect) these parts, be sure to follow procedures described in Precautions for Air Bag System Service. 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, instrument panel, or any other air bag system components.
Any modifications can adversely affect air bag system performance and lead to injury.

- For vehicle equipped with advanced air bag system, do not modify the front seats (driver and passenger) and do not install accessory items like a seat cover, cushion, etc. on the passenger seat. Otherwise, the air bag system may not operate properly and personal injury may result.
- If the vehicle is exposed to temperatures over 93 °C (199.43 °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.







Diagnosis
- When troubleshooting the air bag system, be sure to follow Air Bag Diagnostic System Check. Bypassing these procedures may result in extended diagnostic time, incorrect diagnosis, and incorrect replacement of parts.
- 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, rear side and curtain) and seat belt pretensioners (driver and passenger). Resistance measurement of these components is very dangerous as the electric current from the tester may deploy the air bag or activate the pretensioner.






Servicing and Handling

WARNING:
Many of service procedures require disconnection of negative battery cable or "A/B" fuse to avoid an accidental deployment.
Driver, Passenger, Side (Front Seat and Rear Seat) and Curtain Air Bag (Inflator) Modules.
- For handling and storage of a live air bag (inflator) modules and seat belt pretensioners, select a place where the ambient temperature is below 65 °C (149 °F) and these is no high humidity and 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, doing so will help minimize the chance of injury in case of an accidental deployment. Never carry the air bag (inflator) module by the wires or connector on the underside of the module. When leaving or storing live air bag (inflator) module unattended on workbench or other surface, always place it with the bag (trim cover) facing up but not against the surface. It is also prohibited to place anything on top of the trim cover and stack air bag (inflator) modules. This is necessary to provide air bag with a free space to expand in the event of its accidental deployment. Otherwise, personal injury may result.
- 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 before disposal.
- The air bag (inflator) module immediately after deployment is very hot. Wait for at least half an hour to cool it down before proceeding to the next 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
- For handling and storage of an SDM, select a place where the ambient temperature is below 65 °C (149 °F), and there is no high humidity and electric noise.
- Handle the SDM very carefully during service procedures. Never strike or jar SDM.
- Never power up the air bag system when SDM is not rigidly attached to the vehicle. All SDM and mounting bracket fasteners must be carefully torqued and the arrow must point toward the front of the vehicle to ensure proper operation of the air bag system.
When the SDM is powered while not rigidly attached to the vehicle, the SDM could activate air bag (inflator) 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 is below 65 °C (149 °F) and there is no high humidity and electric noise.
- Never carry seat belt pretensioner by its wire or connector of pretensioner. When placing a live seat belt pretensioner on the workbench or some place like that, never put something on seat belt pretensioner. Otherwise, personal injury may result.
- Never dispose of live (inactivated) seat belt pretensioners (driver 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 before disposal.
- The seat belt pretensioner immediately after activation is very hot. Wait for at least half an hour to cool it down before proceeding to the next work.
- As with many service procedures, gloves and safety glasses should be worn to prevent possible irritation of skin or eyes.


CAUTION:
- Even when the accident was not severe enough to cause air bags to activate, be sure to inspect system parts and other related parts according to the instructions under Repair and Inspection Required after Accident.
- When servicing parts other than air bag system, if shocks may be applied to air bag system component parts, remove those parts beforehand.
- Carefully handle the following components not to drop or otherwise give impact to them: the driver, passenger, side and curtain air bag (inflator) modules; the driver and passenger seat belt pretensioners; the forward and side sensors; and the SDM. If any of these components receives impact, never try to disassemble and repair it but replace it with a new one.
- Grease, cleaning agent, oil, water, etc. on air bag (inflator) modules (driver, passenger, side and curtain) or seat belt pretensioners (drive and passenger) should be wiped off immediately with a dry cloth.
- Air bag wire harness is included in the main, instrument panel and floor harness. Air bag wire harness can be identified easily by a yellow protection tube or tape covering the connector end of the harness. Handle it very carefully when handling it.
- When air bag wire harness broken or damaged wires, connectors or terminals, replace the whole wire harness assembly.
- Do not apply power to the air bag system unless all components are connected or diagnostic flow requires to do so, or DTC will be set.
- Never use air bag system components from another vehicle.
- When performing electric welding, be sure to disconnect all air bag (inflator) module connectors and pretensioner harness.
- Never expose air bag system components directly to hot air (for drying or baking the vehicle after painting) or flames.
- WARNING / CAUTION labels are attached on every of air bag system component. Be sure to follow the instructions.
- After vehicle is completely repaired, perform Air Bag Diagnostic System Check.
