Cruise Control - Electrical: Description: General
Cruise control is switched on by pressing the cruise control master switch mounted on the drivers side of the fascia. The 'Set +' and 'Res' switches mounted on the steering wheel allow the driver to either set the vehicle speed as required or resume the last cruising speed set.
The cruise control system uses mechanical, electrical and vacuum operated devices to maintain vehicle speed at a setting selected by the driver. As vehicle speed changes due to changes in road gradients, so the cruise control ECU operates the cruise control pump, continually moving the cruise control actuator to maintain the set vehicle speed.
Should the driver wish to increase the speed of the vehicle, the 'Set +' switch should be pressed and held. The vehicle will accelerate until the switch is released. As the 'Set +' switch is released, the cruise control ECU will store the new cruise speed in its memory.
With cruise control switched on, it is possible to press the accelerator pedal and accelerate through the memorized set speed. When the accelerator is released, the cruise control ECU will automatically return the vehicle to its set speed.
Cruise control operation can be suspended by one of the following ways:
- By pressing the 'Res' switch.
- pressing the brake pedal.
- The gearbox is placed in park, neutral, or reverse.
- Hill Descent Control (HDC) is active.
- Engine rev's are too high.
Under all these conditions, the cruise control set speed will be memorized. Cruise control operation can be resumed by pressing the 'Res' switch.
Cruise control operation can be cancelled in one of two ways:
- By pressing the cruise control master switch located on the drivers side of the fascia.
- By switching the ignition off.
In both these cases, the cruise control set speed will be lost.
