Engine management system - Td5 (Cruise control): Description and operation (page 2 of 2)

Cruise control resumption Cruise control can be resumed at the previously set speed, provided the set speed has not been erased from the ECM's memory as described above.

To resume cruise control operation to the previously set speed, depress the RES switch once when the following conditions are met: l A set speed is stored in the ECM. l Vehicle speed is above 22 mph (35 km/h). l The brake pedal is not pressed. l The clutch pedal is not pressed (manual transmission only). l The transmission is not in Park, Reverse or Neutral (automatic transmission only).

The ECM activates the cruise control system at the stored speed.

Accelerating while cruise control is active There are three ways of increasing vehicle speed when cruise control is active: l Temporarily increase vehicle speed (e.g. when overtaking another vehicle). l Increase vehicle set speed in 1 mph (1.5 km/h) increments. l Increase vehicle set speed.

To temporarily increase vehicle speed press the accelerator pedal until the desired speed is reached.

When the accelerator pedal is released, the vehicle coasts back to the set speed. When it reaches the set speed, cruise control operation continues.

To increase the vehicle set speed in 1 mph (1.5 km/h) increments, tap the SET+ switch. Each tap on the switch increases vehicle speed.

To increase the vehicle set speed, press and hold the SET+ switch until the desired set speed is reached.

Vehicle set speed will increase if the following conditions are met: l The vehicle is under cruise control operation. l Vehicle speed is above 22 mph (35 km/h). l The brake pedal is not pressed. l The clutch pedal is not pressed (manual transmission only). l The transmission is not in Park, Reverse or Neutral (automatic transmission only).

The vehicle responds as follows: l If the driver accelerates using the throttle pedal, the ECM increases vehicle speed using the TP sensor signal. When the driver releases the accelerator pedal, the vehicle returns to the set speed. l If the SET+ switch is tapped the stored speed and vehicle speed increases by 1 mph (1.5 km/h) per tap on the switch. l If the driver presses and holds the SET+ switch the vehicle speed will increase and will hold the speed when the switch is released.

Switching off cruise control Switching off cruise control allows the driver to regain control of vehicle speed, and erases the set road speed from the ECM's memory.

To switch off cruise control, press the cruise control master switch to the off position.

When the cruise control master switch is switched off, the ECM deactivates cruise control and the driver regains control of vehicle speed.
