Cruise Control: Description and Operation

Speed Control

The speed control system consists of the following components:

- Speed control switches
- Speed control deactivator switch (part of the stoplamp switch)
- Stoplamp switch
- Speed control indicator
- Clutch pedal speed control deactivator switch (manual transaxle)
- PCM
- Electronically-controlled throttle body
- Clockspring

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

It is normal for the engine rpm to increase slightly and then drop off slowly when the clutch pedal is applied during operation.

The speed control functions include:

- turning the speed control system on.
- setting and maintaining the desired vehicle speed.
- accelerating the vehicle speed.
- decelerating the vehicle speed.
- resuming the prior vehicle speed.
- turning the vehicle speed control system off.
