The steering wheel and column has 4 primary functions:
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 of 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:
| • | The ignition switch assembly |
| • | The steering column lock |
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.
| • | The headlamp dimmer switch |
| • | The wiper/washer switch |
| • | The horn pad/cruise control switch |
| • | The redundant radio/entertainment system controls |
| • | The tilt or tilt/telescoping functions |
| • | The navigation/OnStar® features |
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.
