Operation CHARM: Car repair manuals for everyone.

General Description

The cruise control system maintains a desired vehicle speed under normal driving conditions. The system also has the capability to coast, resume speed, accelerate, and increase or decrease speed in 1.6 kph (1 mph) increments.

The main components of the system are the multifunction switch, cruise control module, vehicle speed sensor (VSS), release switches, and electrical harness.

The cruise control module contains an electronic controller and an electric stepper motor. The controller monitors vehicle speed and operates the electric stepper motor. The motor moves a ribbon, which is connected by a cable to the throttle, in response to the controller in order to maintain the desired cruise speed.




The cruise control module contains a low speed lockout that prevents system engagement below a minimum speed of approximately 40 kph (25 mph). The controller operates in response to the control switches located on the multifunction switch.

Release switches are used to disengage the cruise control. When either the brake or clutch pedal is depressed, the cruise control system is electrically disengaged, and the throttle returns to the idle position.

CAUTION: To keep the vehicle under control and to prevent possible vehicle damage, do not use the cruise control on slippery roads. It is not recommended to use the cruise control in conditions such as on winding roads or in traffic of varying volume. When traveling down a steeply graded hill, the cruise control should be disengaged by depressing the brake or clutch pedal lightly. The transmission can then be shifted to a lower gear range to help control vehicle speed.
