### System Outline

Cruise control system is constant speed driving control in which fuel injection is controlled by switch operation at hand without stepping on the acceleration pedal when driving at constant speed is desired.

1.Set Operation

When the MAIN SW is turned on, the system starts preparations necessary for the cruise control and turns on the indicator light in the combination meter.

2.Set Speed Control

When the SET/COAST SW is operated with the cruise control main SW turned on during travelling, the constant vehicle speed is controlled.

3.Coast Control

When SET/COAST SW is continuously turned on, fuel injection is controlled for decreasing, which reduces the speed of vehicle.
Every time the SET/COAST SW is turned on instantaneously, the vehicle speed is decelerated approximately 1.6 km/h.

4.Accel Control

When RESUME/ACCEL SW is continuously turned on, fuel injection is controlled for increasing, which accelerates the vehicle.
Every time the RESUME/ACCEL SW is turned on instantaneously, the vehicle speed is accelerated approximately 1.6 km/h.

5.Resume Control

When the vehicle speed is within the low speed limit (Approximately 40 km/h, 25 mph) if the cruise control is cancelled, use of the RESUME/ACCEL SW accelerates the vehicle to the speed level used before canceling the cruise control.

6.Manual Cancel Mechanism

If any of the following signals is input during cruise control travelling, the cruise control is cancelled.

*The stop light SW is turned on.

*The CANCEL SW is turned on.

*The MAIN SW is turned off.

7.Auto Cancel Function

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

*The stop light SW wiring is faulty or shortcircuited.

*The vehicle speed signal is faulty.

*Fuel injection system abnormal

8.Overdrive Control Function

Overdrive is sometimes cut off on gradients during cruise control driving. When end of climbing gradient is determined by throttle opening degree information after overdrive is canceled, control is reset to overdrive condition after overdrive resetting timer operation. Also, when overdrive is cut off during accelerator control or resuming control, control is reset to overdrive condition when accelerator control or resuming control is finished.
