1. Verify the following conditions before centering the SIR coil: The wheels on the vehicle are straight ahead. The block tooth (1) of the steering shaft assembly is in the 12 o'clock position. The ignition switch is in the LOCK position.
2. If the front (5) of the SIR coil has a centering window (4), and the back side (2) includes a spring service lock (1), perform the following steps: Hold the SIR coil with the face up. While depressing the spring service lock, rotate the coil hub clockwise until the coil ribbon stops. Rotate the coil hub slowly, counterclockwise, until the centering window appears yellow and both arrows (3) line up. Release spring service lock between the locking tab. The SIR coil is now centered. Align the centered SIR coil with the horn tower and slide onto the steering shaft assembly.
3. If the front (4) of the SIR coil has a centering window (3), and the back side (1) includes NO spring service lock, perform the following steps: Hold the SIR coil with the face up. Rotate the coil hub clockwise until the coil ribbon stops. Rotate the coil hub slowly, counterclockwise until the centering window appears yellow and both arrows (2) line up. This is the CENTER position. While holding the coil hub in the CENTER position, align the SIR coil with the horn tower and slide onto the steering shaft assembly.
4. If the front side (3) of the SIR coil has NO centering window, but the back side (2) includes a spring service lock (1), perform the following steps: Hold the SIR coil with the back side up. While depressing the spring service lock, rotate the coil hub in the direction of the arrow (4) until the coil ribbon stops. Still pressing the spring service lock, rotate the coil hub in the opposite direction 2 1/2 revolutions. Release the spring service lock between locking tabs. The SIR coil is now centered. Align the centered SIR coil with the horn tower and slide onto the steering shaft assembly.
5. For the front side (2) of the SIR coil has NO centering window, and the back side (1) includes NO spring service lock, perform the following steps: Hold the SIR coil with the face up. Rotate the coil hub in the direction of the arrow until the coil ribbon stops. Rotate the coil hub, slowly, counterclockwise, for 2 1/2 revolutions. This is the CENTER position. While maintaining the coil hub in the CENTER position, align the centered SIR coil with the horn tower and slide onto the steering shaft assembly.
6. If double wire harness strap is installed onto the wire harness assembly and column, you must route the wires up against the steering column. One wire harness strap will surround one lead other wire harness strap will surround all leads to the steering column.

Vehicle Steering

The steering wheel is the first link between the driver and the vehicle. The steering wheel is fastened to a steering shaft within the column. At the lower end the column, the intermediate shaft connects the column to the steering gear.

Vehicle Security (Some Vehicle Models)

Theft deterrent components are mounted and designed into the steering column. The following components allow the column to be locked in order to minimize theft

1. The ignition switch
2. The steering column lock (manual transmission only)
3. The ignition cylinder

Driver Convenience

The steering wheel and column may also have driver controls attached for convenience and comfort. The following controls may be mounted on or near the steering wheel or column.

1. The turn signal switch.
2. The hazard switch
3. The headlamp dimmer switch
4. The wiper/washer switch
5. The horn pad/cruise control switch
6. The redundant radio/entertainment system controls
7. The tilt or tilt/telescoping functions
8. The navigation/On Star® features
9. The HVAC controls

Driver Safety

The energy-absorbing steering column compresses in the event of a front-end collision, which reduces the chance of injury to the driver. The mounting capsules break away from the mounting bracket in the event of an accident.
