Driving
– 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.
Temporarily exceeding the
speed setting
► Fully depress the accelerator pedal.
The speed limiter is temporarily deactivated and
the displayed speed setting flashes.
► Release the accelerator pedal to return to
below the speed setting.
When exceeding the speed is not due to the
driver's action (e.g. in case of a steep slope), an
audible signal is triggered immediately.
On a steep descent or in the event of
sharp acceleration, the speed limiter will
not be able to prevent the vehicle from
exceeding the speed setting.
If necessary, apply the brakes to control your
vehicle's speed.
When the vehicle speed returns to the speed
setting level, the speed limiter operates again:
the speed setting display becomes fixed again.

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.
Cruise control - Specific
recommendations
The cruise control function does not
guarantee compliance with the maximum
authorised speed and the safety distance
between vehicles, the driver remains
responsible for their driving.
In the interest of public safety, only use cruise
control if the traffic conditions enable vehicles
to drive at a steady speed and maintain an
adequate safety distance.
Remain vigilant while cruise control is
activated. If you press and hold one of the
speed setting modification buttons, your
vehicle may change speed very abruptly.
When descending a steep hill, the cruise
control system cannot prevent the vehicle
from exceeding the set speed. Brake if
necessary to control the vehicle speed.
On steep climbs or when towing, the set
speed may not be reached or maintained.
Exceeding the programmed speed
setting
You can temporarily exceed the speed
setting by pressing the accelerator pedal (the
programmed speed flashes).
To return to the speed setting, release the
accelerator pedal (when the set speed is
reached again, the displayed speed stops
flashing).
Operating limits
Never use the system in the following
situations:
– In an urban area with the risk of
pedestrians crossing the road.
– In heavy traffic (except versions with the
Stop & Go function).
– On winding or steep roads.
– On slippery or flooded roads.
– In poor weather conditions.
– In the event of restricted visibility for the
driver.
– Driving on a speed circuit.
– Driving on a rolling road.
– When using a 'space-saver' type spare
wheel.

or studded tyres.
