Cruise Control Operation

The cruise control system is a constant vehicle speed controller which makes it 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 switch is turned on, the system begins preparing to activate the cruise control and turns on the indicator light on the combination meter.

2. Set Speed Control 

   If the - SET switch is pressed while the vehicle is being driven and the cruise control ON-OFF switch has been turned on, the cruise control will be activated, the current speed will be recorded, and the vehicle will be maintained at that speed.

3. Coast Control 

   If the - SET switch is pressed and held down while driving when the cruise control is active, the ECM adjusts the throttle valve to gradually and continually decelerate the vehicle.

   If the - SET switch is only pressed momentarily however, the vehicle will be decelerated by approx. 1.6 km/h in a single action.

4. Acceleration Control 

   If the + RES switch is pressed and held down while driving when the cruise control is active, the ECM adjusts the throttle valve to gradually and continually accelerate the vehicle.

   If the + RES switch is only pressed momentarily however, the vehicle will be accelerated by approx. 1.6 km/h in a single action.

5. Resume Control 

   If the vehicle speed is below the low speed limit (Approx. 40 km/h) when the cruise control is cancelled, pressing the + RES switch will reactivate the cruise control and return the vehicle to the speed which was set before the cruise control was cancelled.

6. Manual Cancel Mechanism 

   If any one of the following signals are received while driving when the cruise control is active, the cruise control will be canceled.

   * The stop light switch assembly comes on.

   * The CANCEL switch is turned on.

   * The ON-OFF switch is turned off.

   * The "D" position circuit in the park/neutral position switch is switched from ON to OFF.

   * The transmission is shifted from "D" to "N".

   * The transmission is shifted from 6, 5 or 4 to 3, 2 or 1 in S mode.

7. Auto Cancel Function 

   If any of the following conditions are detected, the cruise control will be canceled:

   * Failure in the stop light switch assembly wiring.

   * Abnormality in the vehicle speed signal.

   * Malfunction in the electronically controlled throttle parts.

   * The vehicle speed falls below than the low speed limit.

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

   * The VSC activates.

8. Shift-Down Control 

   If the vehicle climbs a hill while driving when the cruise control is active, the gear may be shifted down by the A/T control. Then when the hill is judged to have finished, from throttle opening information, the gear will be shifted back up after a short time.
