Emergency braking
In the event of a failure of the main service
brake or in an exceptional situation (e.g. driver
taken ill, under instruction, etc.) a continuous
pull on the control lever will brake the vehicle.
Braking takes place while the control lever is
being pulled. It is interrupted if the control lever
is released.
The ABS and DSC systems provide stability of
the vehicle during emergency braking.
If the emergency braking malfunctions, the
message "Parking brake control faulty" will be
displayed.
If a failure of the ABS and DSC systems occurs,
signalled by the illumination of one or both
warning lamps in the instrument panel, then
stability of the vehicle is no longer guaranteed.
In this event, stability must be assured by the
driver by repeating alternate "pull-release"
actions on the control lever until the vehicle is
immobilised.The emergency braking should only be
used in an exceptional situation.
Repeat this procedure to reactivate automatic
operation.
Reactivation of automatic operation is
confirmed by the indicator lamp in the
instrument panel going off.
Deactivating automatic operation
In some situations, such as very cold weather
or towing (caravan, recovery), it may be
necessary to deactivate automatic operation of
the system.

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 grime (dust, mud...) or in certain weather conditions (snow, ice...).
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.
