Cruise Control: Description and Operation

General Description
The cruise control keeps the vehicle running at a fixed speed until a signal canceling this fixed speed is received. When the main switch AUTO CRUISE is turned on with the vehicle in the running mode, the battery voltage is applied to the control unit. When a signal from the control switch is input to the control unit while the vehicle is in this state, the cruise control actuator is activated to operate the system. Also, while the system is operating, the AUTO CRUISE indicator light in the meter assembly lights up.

1. SET/COAST Switch Function
1. Set Function: When the SET/COAST switch is pressed and released with the main switch on, the speed at which the vehicle is running at that moment is stored in the memory, and the vehicle automatically runs at the speed stored.
2. Coast-Down Function: When the SET/COAST switch is kept on while the vehicle is running, the vehicle decelerates during that time. The speed at which vehicle is running when the control switch is turned off is stored in the memory, and the vehicle automatically returns to the stored speed.
3. Tap-Down Function: When the SET/COAST switch is turned on and off instantaneously while the vehicle is running, the vehicle decelerates a mile for each on/off operation. The vehicle speed at which the vehicle was running when the SET/COAST was turned off last is stored in the memory, and the vehicle automatically returns to this stored speed.

2. RESUME/ACCEL Switch Function
1. Resume Function: When the RESUME, ACCEL switch is turned on/off after the system is temporarily deactivated by pressing the brake or clutch pedal while the vehicle is running, the vehicle resumes, the speed stored before the system was released.
2. Accelerate Function: When the RESUME/ACCEL switch is kept on after the system is released completely, the vehicle accelerates its speed during that time. The vehicle speed at which the vehicle was running when the switch was turned off is stored in the memory, and the vehicle automatically returns to this speed.
3. Tap-Up Function: When the RESUME/ACCEL switch is turned on and off instantaneously while the vehicle is running, the vehicle decelerates a mile for each on/off operation. The vehicle speed at which the vehicle was running when the switch was turned off last is stored in the memory, and the vehicle automatically returns to this stored speed.

3. CANCEL Function
1. Temporary Cancellation:
- When the brake pedal is pressed.
- When the clutch pedal is pressed. (M/T)
- When the select lever is shifted to any position other than D, 3, 2 or L. (A/T)
- When the vehicle speed has decreased about 12.5 mph (20 kph) or more than the stored speed.
2. Complete Cancellation:
- When the starter switch or the main switch is turned off.
- When the failsafe function is activated.
