Chevrolet Trax: Sir service precautions

General Service Instructions

WARNING: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Refer to SIR Disabling and Enabling . Failure to observe the correct procedure could cause deployment of the SIR components, personal injury, or unnecessary SIR system repairs.

NOTE: The Inflatable Restraint Sensing and Diagnostic Module (SDM) maintains a reserved energy supply. The reserved energy supply provides deployment power for the SIR air bags. Deployment power may be available for up to 2 minutes after disconnecting the vehicle power. Disabling the SIR system prevents deployment of the SIR air bags from the reserved energy supply.

NOTE: The following are general service instructions which must be followed in order to properly repair the vehicle and return it to its original integrity:

• Do not expose air bags to temperatures above 85 ºC (185 ºF)
• Verify the correct replacement part number. Do not substitute a component from a different vehicle
• Use only original GM replacement parts available from your authorized GM dealer. Do not use salvaged parts for repairs to the SIR system

NOTE: Discard any of the following components if it has been dropped from a height of 80 cm (15.75 in) or greater:

• Inflatable Restraint Sensing and Diagnostic Module
• Passenger instrument panel air bag
• Driver steering wheel air bag
• Driver steering wheel air bag coil
