1. Set switch (B) to ON.
2. Accelerate to desired cruise speed.
NOTE: The cruise control cannot be engaged at speeds below 22 mph (35 km/h).
3. Depress SET SPEED switch (A).
Operating brake pedal
This will automatically disengage the cruise control. Previously selected cruise speed is retained in the
memory and by momentarily setting the switch to RESUME position that speed will be re-engaged.
NOTE:
The vehicle will accelerate very quickly should there be a substantial speed differential when the switch
is reset to RESUME. It is therefore recommended that the vehicle be accelerated manually and the
switch reset to RESUME once the speed differential has been reduced.
Acceleration
Momentary acceleration, such as for passing, does not interrupt cruise control operation. The previously
selected speed will be maintained without having to set switch to RESUME.
To disengage the cruise control system:
Set switch (B) to position OFF, or depress brake pedal, or depress clutch pedal.
Switching off the starting (ignition) switch is will automatically disengage the cruise control system.
WARNING!
The cruise control should not be used in heavy traffic or when driving on wet or slippery roads.
If the gear shift is moved to Neutral while the cruise control is engaged, then depress the brake pedal
momentarily, or set the cruise control switch (B) to OFF. This will disengage the cruise control and
prevent overreving the engine.
NOTE: When driving on a grade, actual vehicle speed may vary slightly from the set cruise control
speed.
