System Outline

The cruise control system is a constant vehicle speed controller with which it is possible to automatically adjust the opening of the engine throttle valve without depressing the accelerator pedal, but by operating a switch instead.

1. Set Operation 

   When the ON-OFF SW is turned on, the system begins the preparations necessary for the cruise control and turns on the indicator light in the combination meter.

2. Set Speed Control 

   When the - SET SW is pressed while the cruise control SW is turned on and the vehicle is being driven, the vehicle will be maintained at the speed at which the - SET SW is released.

3. Coast Control 

   If the - SET SW is held down while driving with the cruise control active, the engine control module adjusts the throttle valve to gradually and continually decelerate the vehicle. Every time the - SET SW is pressed momentarily, the vehicle will be decelerated approximately 1.6 km/h.

4. Accel Control 

   If the + RES SW is held down while driving with the cruise control active, the engine control module adjusts the throttle valve to gradually and continually accelerate the vehicle. Every time the + RES SW is pressed momentarily, the vehicle will be accelerated approximately 1.6 km/h.

5. Resume Control 

   If the vehicle speed is above the low speed limit (Approximately 40 km/h, 25 mph) and the cruise control has been cancelled, pressing the + RES SW will accelerate the vehicle to the speed which was set before the cruise control was cancelled.

6. Manual Cancel Mechanism 

   If any of the following signals is received while driving with the cruise control active, the cruise control will be cancelled.

   * The stop lamp SW is turned on.

   * The CANCEL SW is turned on.

   * The ON-OFF SW is turned off.

   * The gear is shifted from the D position to another position (A/T).

   * The clutch pedal is depressed (M/T).

7. Auto Cancel Function 

   If any of the following conditions is encountered, the cruise control will be automatically cancelled.

   * The stop lamp SW wiring is faulty or short-circuited.

   * The vehicle speed signal is faulty.

   * The electronically controlled throttle malfunctions.

   * The actual vehicle speed falls to -16 km/h less than the set speed.

   * The actual vehicle speed falls below the minimum speed limit.

8. Overdrive Control Function 

   The overdrive will sometimes be cut off on a steep hill while driving with the cruise control active. When the hill climbing is determined to have finished (determined using throttle opening information) and the overdrive was canceled, the overdrive will resume after the overdrive timer expires. Also, when the overdrive is cut off while the accelerator was being used manually, the overdrive won't be resumed until the acceleration has finished.
