8B-4 CRUISE CONTROL SYSTEM
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 12.5mph 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.

Vehicle speed is about 38 km/h mph.

Speed becomes 20 (12.5) km/h (mph) or less form the speed memorized by Control unit.
