Caution: In order to reduce the chance of personal injury and/or property damage, carefully observe the instructions that follow:

Service information provided by General Motors Corporation is intended for use by professional, qualified technicians. Attempting repairs or service without the appropriate training, tools, and equipment could cause injury to you or others. This could also damage the vehicle or cause the vehicle to operate improperly.

Proper vehicle service and repair are important to the safety of the service technician and to the safe, reliable operation of all motor vehicles. If you need to replace a part, use the same part number or an equivalent part. Do not use a replacement part of lesser quality.

The service procedures we recommend and describe in this manual are effective methods of performing service and repair. Some of the procedures require the use of tools that are designed for specific purposes.

Accordingly, any person who intends to use a replacement part, a service procedure, or a tool that is not recommended by General Motors must first establish that there is no jeopardy to personal safety or the safe operation of the vehicle.

This manual contains "Cautions" that you must observe carefully in order to reduce the risk of personal injury to yourself or others This manual also contains "Notices" that must be carefully followed in order to avoid improper service that may damage the vehicle, or damage the tools or equipment. These "Cautions" and "Notices" are not exhaustive. General Motors can not possibly warn of all the potentially hazardous consequences of your failure to follow these instructions.

If the vehicle being serviced is equipped with a Supplemental Inflatable Restraint (SIR), refer to the "Cautions" in the following service manual section/service category type before performing a service on or around SIR components or wiring:

   • Sub-Section 9J -- Supplemental Inflatable Restraints, refer to "Cautions" under On-Vehicle Service and the SIR Component Wiring Location view in the C/K Truck Service Manual, or
   • Section -- Body and Accessories, Sub-Section -- Restraint, refer to "Cautions" under On-Vehicle Service and the SIR Component Wiring Location view in the C/K Truck Service Manual.
Failure to follow these "Cautions" could cause air bag deployment, personal injury, or otherwise unneeded SIR repairs.

In order to help avoid accidental air bag deployment and personal injury, whenever you service a vehicle that requires repair of the SIR and another vehicle system, we recommend that you first repair the SIR, then go on to the other system.
