The cruise control system is a constant vehicle speed controller which controls the opening angle of the engine throttle valve
by the SW, and allows driving at a constant speed without depressing the accelerator pedal.
Set Operation
When the ON-OFF SW is turned on, the systems starts preparations for cruise control and turns on the indicator light in the
combination meter.
Set Speed Control
When the - SET SW is operated with the ON-OFF SW turned on during driving, the speed is controlled at a constant speed.
Coast Control
When the - SET SW is kept turned on during cruise control driving, the engine control module controls the throttle valve to
decelerate the vehicle speed.
Every time the - SET SW is turned on instantaneously, the vehicle speed is decelerated approx. 1.5 km/h.
Accel Control
When the + RES SW is kept turned on during cruise control driving, the engine control module controls the throttle valve to
accelerate the vehicle speed.
Every time the + RES SW is turned on instantaneously, the vehicle speed is accelerated approx. 1.5 km/h.
Resume Control
If the vehicle speed is within the low speed limit (Approx. 40 km/h, 25 mph) when canceling the cruise control, operation of
the + RES SW accelerates the vehicle speed and resumes the level before canceling the cruise control.
Manual Cancel Mechanism
If any of the following signals are input during cruise control driving, the cruise control is canceled.
*The stop light SW is on
*The CANCEL SW is turned on
*The ON-OFF SW is turned off
Auto Cancel Function
If any of the following conditions are detected, the cruise control is canceled:
*Failure in the stop light SW wiring
*Abnormality in the vehicle speed signal
*Malfunction in the electronically controlled throttle parts
Overdrive Function
The overdrive may be canceled if the vehicle travels on a upward slope during cruise control driving. After the overdrive is
canceled, if the vehicle speed exceeds the overdrive return speed (Set speed ( 2 km/h, 1.2 mph) ) and it is determined that
the slope has finished, and the vehicle returns to overdrive mode again.
