8B-2  CRUISE CONTROL SYSTEM 

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 (Engine control module). When a signal from 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 cruise 
control set 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 

stored speed. 

2.  COAST-down Function: When the SET/COAST switch is kept on while the vehicle in running, the vehicle 

decelerates during that time. The speed at which vehicle is running when the control switch is pressed in the 

memory, and the vehicle automatically returns to the stored speed. 

3.  Tap-down Function: When the SET/COAST switch is pressed and released 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 released 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, and the vehicle automatically runs at the stored speed. 

2.  Accelerate Function: When the RESUME/ACCEL switch is kept on 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: 

•  Brake pedal is pressed. 
•  Clutch pedal is pressed. (M/T) 
•  Select lever is shifted to any position other than “D”, “3”, “2” or “L”. (A/T) 
•  Cancel switch is operated. 
•  Vehicle speed exceeds about 20 km/h over the vehicle speed stored in the memory. 

Turning the RESUME/ACCEL switch will return the vehicle to the speed stored in the cruise control memory. 

2.  Complete Cancellation: 

•  Starter switch or the main switch is turned off. 
•  Fail-safe function is activated.
