Cruise Control: Description and Operation

Cruise Control

The cruise control system consists of the following components:

- Cruise control switches
- Cruise control indicator
- PCM
- Electronically-controlled throttle body
- Stoplamp switch
- Clockspring

The cruise control system is controlled by the PCM. The cruise control system is designed to maintain a selected vehicle speed between 40 km/h (25 mph) and the maximum limited vehicle speed. The cruise control system is controlled by the steering wheel mounted switches (ON, OFF, SET+, SET-, and RESUME) and the brake pedal. The steering wheel mounted switches are hardwired to the PCM.

During normal driving, the vehicle speed can vary slightly from the set speed due to road conditions. The vehicle speed can fluctuate when driving up and down a steep hill. If the vehicle speed decreases more than 16 km/h (10 mph) below the set speed, the cruise control disengages.

When a MyKey(TM) is used and the MyKey(TM) max speed limiter is turned on, the vehicle speed cannot be set to exceed 130 km/h (80 mph).
