Switching on
The cruise control is switched on manually,
it requires a vehicle speed of between 18 and
112
mph (30 and 180 km/h).
An automatic gearbox must be in position D
or M . Other wise, the last setting made will be used
when switching on the system.
Switching off the ignition cancels any
programmed speed setting.
When the cruise control is operating,
Stop & Start is automatically
deactivated.

The dynamic cruise control can be paused
manually by:
-

a

the cruise control is paused. The driver
should press the accelerator pedal to
move off, then reactivate the system
by exceeding 18
mph (30 km/h) and
pressing button
2, 3 or 4 .
If the driver takes no action following
this immobilisation, the electric parking

Three predefined inter-vehicle distance settings
are offered:
-

Operating fault
In the event of a fault with the cruise
control, you are alerted by the
illumination of this warning lamp
and the display of a message in the
instrument panel, accompanied by an
audible signal.
The cruise control operates by day and at night, in fog or moderate rainfall.
However, it is strongly recommended that you always keep a safe distance from vehicles
ahead, depending on the driving conditions, the weather and the road sur face.
Use the cruise control only where the driving conditions allow running at a constant speed
and at an adequate safe distance.
Do not use the cruise control in urban areas, heavy traffic, on winding or steep roads, on
slippery or flooded sur faces, in snow, if the front bumper is damaged or if the brake lamps
are faulty.
In certain circumstances, it may not be possible for the speed setting to be maintained or
even attained: loaded vehicle, ascending a steep hill, etc.
The system is not intended for the following situations:
-

t

he front end of the vehicle has been modified (addition of driving lamps, paint on the
bumper),
-

d

riving on a racing circuit,
-

r

unning on a rolling road,
-

u

se of snow chains, non-slip covers or studded tyres. Have the system checked by a CITROËN
dealer or a qualified workshop.
The operation of the radar, located in the front bumper, may be disturbed by accumulations
of dirt (dust, mud, etc.) or in certain weather conditions (snow, ice, etc.).
The message "SYSTEM INACTIVE: Visibility reduced" is displayed to signal that the system
has been put into standby.
Clean the front bumper regularly.
When painting or touching up the paint on the front bumper, consult a CITROËN dealer or a
qualified workshop. Certain types of paint could hinder the operation of the radar. The use of mats not approved by CITROËN may inter fere with the operation of the cruise
control.
To avoid any risk of jamming the pedals:
-

e

nsure that mats are secured correctly,
-

n

ever fit one mat on top of another.
