AIR BAG RELATED SERVICE PRECAUTIONS




CAUTION
To avoid deployment when servicing the sir system or components in the immediate area, do NOT use electrical test equipment such as battery or A.C. powered voltmeter, ohmmeter, etc. or any type of tester other than specified. Do NOT use a non-powered probe tester. To avoid personal injury, all precautions must be strictly adhered to.



Wait at least 90 seconds from the time that the ignition switch is turned to the lock position and the battery is disconnected before performing any further work.
 
Do NOT disassemble any air bag system components.
 
ALWAYS carry an inflator module with the trim cover pointed away.
 
ALWAYS place an inflator module on the workbench with the pad side facing upward, away from loose objects.
 
After deployment, the air bag surface may contain sodium hydroxide dust. ALWAYS wear gloves and safety glasses when handling the assembly. Wash hands with mild soap and water afterwards.
 
The SRS must be inspected 10 years after the vehicle's manufacture date shown on the certification label located on the left front door latch post.
 
NEVER measure the resistance of the air bag. This may cause the air bag to deploy due to the current of the ohmmeter.
 
Before disconnecting the negative battery cable, make a record of the contents memorized by each memory system like the clock, audio, etc. When service or repairs are completed make certain to reset these memory systems.
 
ALWAYS touch a vehicle ground after sliding across a vehicle seat or walking across vinyl or carpeted floors to avoid static charge damage.
 
The sensors, mounting brackets and wiring harness must NEVER be modified from original design or repaired.
 
NEVER strike or jar a sensor, or deployment could happen.
 
NEVER bake paint on vehicle, such as in a paint booth, or subject the vehicle to temperatures exceeding 200°F (93°C), without disabling the air bag system and removing the air bag, crash zone sensors, SRS diagnosis unit and the spiral cable.
 
NEVER allow welding cables to lay on, near or across any vehicle electrical wiring.
 
Caution labels are important when servicing the air bag system in the field. If they are dirty or damaged, replace them with new ones.
