ciples of operation
The s
p
eed (cruise) control sy
stem is activated by an ON/OFF master switch in the J-gate surround, which has an integral
LED to indicate status.
The steering wheel switches allow the driver to set the speed, increase or decrease the selected speed, cancel and resume
the facility without his/her hand ever leaving the steering wheel
The vehicle speed can be increased an d decreased in increments of 2 kmh (1 mph) by briefly pressing the + or - buttons up
to a maximum of five times.
Alternatively, the + or - button can be held until th e desired speed is reached.
The selected speed (by whichever method) w ill be displayed in the message center.
The system will not function at speeds below 26 kmh (16 mph), and can be cancelled from the master switch, the steering
wheel switches, and by depressing th e brake pedal. The system can be overridden by accelerating as normal.
In
spection and Verification
1.
1. Veri fy the customer concern.
2. 2. Vis
ually inspect for obvious signs of mechanical or electrical damage.
3. 3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding
to the next step.
4. 4. If the cause is not visually evident, verify the symptom, check for DTCs and follow the routines in this section.
