Citroen C4: Cruise control

For more information, refer to the General recommendations on the use of driving and manoeuvring aids and the Specific recommendations on cruise control.

This system automatically maintains the vehicle's speed at the value programmed by the driver (speed setting), without the use of the accelerator pedal.

Cruise control is switched on manually.

It requires a minimum vehicle speed of 25 mph (40 km/h).

With a manual gearbox, third gear or higher must be engaged.

With an automatic gearbox, mode D or second gear or higher in mode M must be engaged.

With a drive selector, mode D or B must be engaged.

Cruise control remains active after changing gear, regardless of the gearbox type, on engines fitted with the Stop & Start function.

Switching off the ignition cancels any speed setting.

Switching on/pausing

► Press button 1 to select the cruise control mode; the function is paused (grey).

► Press 3 upwards/downwards, or press 4-OK to activate the cruise control and save a speed setting as soon as the vehicle speed reaches the desired level (green).

► Pressing button 2-I I> temporarily pauses the function.

► Pressing 2-I I>, 3 or 4-OK again will reactivate cruise control (green).

Cruise control operation is also temporarily interrupted (pause):

- by pressing the brake pedal.

- automatically, if the electronic stability control (ESC) system is triggered.

- by shifting to neutral or engaging reverse gear.

- by using the electric parking brake.

Modifying the speed setting

The cruise control must be active.

To change the speed setting using the vehicle's current speed:

► For steps of +/- 1 mph (1 km/h), make successive short presses upwards/ downwards on 3 to increase/decrease.

► For steps of +/- 5 mph (5 km/h), press and hold upwards/downwards on 3 to increase/ decrease.

Prolonged pressing and holding upwards/downwards on 3 causes a very rapid change in vehicle speed.

As a precaution, we recommend setting a cruise speed fairly close to the current speed of your vehicle, to avoid any sudden acceleration or deceleration of the vehicle.

When the function is activated, the speed setting value can be changed using the speed suggested by the Road signs recognition function displayed on the instrument panel:

- When passing the sign:

► Press 4-OK to save the suggested speed.

This value is then immediately shown as the new speed setting on the instrument panel.

- After passing the sign:

► Press 4-OK. The message "OK?" is displayed to confirm the request to save.

► Press 4-OK again to save the suggested speed. The new speed setting value is displayed on the instrument panel.

Off

► Press 1: the cruise control information display disappears.

Malfunction

In the event of a malfunction, dashes are displayed flashing and then fixed instead of the speed setting.

Have it checked by a CITROËN dealer or a qualified workshop.
