Removal 
 
WARNINGS: Published: 11-May-2011 
 
To avoid accidental deployment, the restraints control module backup power supply must be depleted. Wait at least one 
minute after disconnecting the battery ground cable(s) before commencing any repair or adjustment to the supplemental 
restraint system (SRS), or any component(s) adjacent to the SRS sensors. Failure to follow these instructions may result in 
personal injury. 
 
 
Always wear safety glasses when working on an air bag equipped vehicle and when handling an air bag module. Failure to 
follow this instruction may result in personal injury. 
 
 
To minimize the possibility of premature deployment, do not use radio key code savers when working on the 
supplemental restraint system. Failure to follow this instruction may result in personal injury. 
 
 
To minimize the possibility of injury in the event of premature deployment, always carry a live air bag module with the 
bag and trim cover pointed away from the body. Failure to follow this instruction may result in personal injury. 
 
 
To minimize the possibility of premature deployment, live air bag modules must only be placed on work benches which 
have been ground bonded and with the trim cover facing up. Failure to follow these instructions may result in personal injury. 
 
 
Never probe the electrical connectors of air bag modules or any other supplemental restraint system component. Failure 
to follow this instruction may result in personal injury. 
 
 
Painting over the driver air bag module trim cover or instrument panel could lead to deterioration of the trim cover and air 
bags. Do not for any reason attempt to paint discolored or damaged air bag module trim covers or instrument panel. Install a 
new component. Failure to follow this instruction may result in personal injury. 
NOTES: 
 
 
Some variation in the illustrations may occur, but the essential information is always correct. 
 
 
Removal steps in this procedure may contain installation details. 
 
1. Make the air bag supplemental restraint system (SRS) safe. 
 
Refer to: Standard Workshop Practices (100-00 General Information, Description and Operation).

There are comprehensive instructions on the correct procedures for SRS system repairs, refer to the relevant section of the 
workshop manual 
 
Inspection and Verification 
 
 
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not 
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle 
 
 
NOTE: Check and rectify basic faults before beginning diagnostic routines including pinpoint tests 
 
1. Verify the customer concern by operating the seatbelt 
 
2. Visually inspect for obvious signs of mechanical or electrical damage

Inertia Reel Seatbelts 
 
The vehicle is equipped with (two row one) and (three row two) inertia reel seatbelts 
These seatbelts are "dual sensitive" which means that they have: 
Car sense system - A vehicle motion sensor, which locks the seatbelt webbing under braking, cornering, on steep 
hills and in adverse camber conditions, when parked on a steep incline or driveway or two wheels on a high curb 
Web sense system - A webbing motion sensor, which locks when the seatbelt webbing is extracted suddenly 
The seatbelts in the following positions are equipped with an automatic locking retractor function:

Supplemental Restraint System - Air Bag and Safety Belt Pretensioner 
Supplemental Restraint System (SRS) - Overview 
Description and Operation 
 
OVERVIEW 
 
 
WARNING: All pyrotechnic devices are dangerous. Before performing any procedures on any pyrotechnic device, read all 
information contained within the Standard Workshop Practices section of this manual. 
Refer to: Standard Workshop Practices (100-00 General Information, Description and Operation).  
The SRS (supplemental restraint system) provides additional protection for the vehicle occupants in certain impact conditions. 
The system is controlled by the RCM (restraints control module), which is mounted beneath the floor console. The system 
includes twin stage drivers and front passenger airbags. 
The RCM receives inputs from various sensors around the vehicle and determines which, if any, airbags should be deployed.  
The SRS features an occupant detection system. The occupant detection system comprises a mat fitted inside the front passenger seat. By monitoring the condition of the mat, the RCM can determine if the front passenger seat is occupied. It uses this information to determine which airbags to deploy in the event of an impact. This information is also used to illuminate the 
safety belt instrument cluster warning lamp if the front passenger seat is occupied and the safety belt is not engaged. 
 
North American Specification (NAS) vehicles also feature an occupant classification system. The occupant classification system 
comprises a control module, pressure pad and safety belt tension sensor. The system can determine the size and weight of the 
front seat passenger. This information is transmitted to the RCM over the high speed CAN (controller area network) bus. The  RCM uses this information to help determine which airbags to deploy in the event of an impact.
