Anti-theft protection
Electronic engine immobiliser
The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
This electronic engine immobiliser locks the
engine management system a few minutes
after the ignition is switched off and prevents
starting of the engine by anyone who does not
have the key.
In the event of a malfunction, you are informed
by a message in the instrument panel screen.
In this case, your vehicle does not start; contact
a CITROËN dealer as soon as possible.

Four wheel drive system
System which permits the selection of a transmission mode in relation to the driving conditions.
Three transmission modes are available and can be selected manually by the driver in accordance with his requirements.
You can change transmission mode when
stationary or while driving.
The transmission mode can be selected by
turning the control A.
Selecting the transmission
mode
4WD AUTO (position 1)
The vehicle operates with four wheel drive and
provides optimum traction for all levels of grip.
This is the vehicle's normal and regular
operating mode, the distribution of the torque
between the front and rear axles is controlled
automatically.
The distribution favours the front wheels,
the transfer of torque to the rear wheels is
managed electronically by the control unit
in relation to the level of grip, so providing
optimum road holding.
4WD LOCK (position 2)
The vehicle operates with four wheel drive in
this mode also.
It is recommended when grip is particularly
poor or difficult (sand, mud, slopes, ...).
2WD (position 3)
The vehicle operates with front two wheel drive.
This is suitable for use on a tarmac roads or
where the driver considers that there is no risk
of loss of grip (dry road).
Display in the instrument panel
The transmission mode is displayed in the
form of an intermittent display in the instrument
panel screen when the transmission mode is
selected.The selection of this mode is
recommended when the level of grip
permits.
Driving

119
As the engine torque is applied to all
four wheels, the condition of the tyres
has a considerable impact on the
per formance of the vehicle.
Ensure that all four tyres are in good
condition.
Avoid driving the vehicle in sandy or
muddy areas or in other areas in which
the wheels could spin.
Spinning the wheels places the
transmission components under
pressure and could cause a serious
malfunction.
Do not drive the vehicle through deep
water.
Avoid driving over excessively uneven
terrain (risk of scraping under the body
or of grounding on crossing a bridge).
Operating faults
If the selected transmission mode display
flashes, the vehicle switches automatically to
front "2WD" transmission mode.
It is then no longer possible to select the
transmission mode using the control A .
If the message "SLOW DOWN" is displayed on
the instrument panel, let the transmission cool
down then wait for the display to clear before
setting off again.
If "4WD" and "LOCK" are displayed alternately
and if "SERVICE REQUIRED" is displayed in
the instrument panel, the system has failed and
the safety system has been activated.
Contact a CITROËN dealer or a qualified
workshop without delay. Have your vehicle towed on a
flatbed.
The vehicle must not be towed with the
front or rear wheels on the ground even
if it is in front "2WD" (2 wheel drive)
mode.If the replacement of a tyre is
necessary on 4-wheel drive versions,
it is recommended that all four tyres be
replaced at the same time, ensuring
that the same make, model and size is
used on all wheels.
This is because using tyres of different
sizes, structure or rate of wear could
damage transmission components.

In foggy weather or in snow, the
sunshine sensor may detect sufficient
light. The lighting will not come on
automatically.

ot cover the sunshine sensor, the
associated functions will no longer be

Automatic switching off
When the lighting control stalk is at "dipped or
main beam headlamps", if the ignition switch
is at "LOCK" or "ACC" or if the key has been
removed from the ignition switch, the lamps
switch off automatically when the driver's
door is opened .
Daytime running lamps
Daytime lighting which comes on automatically
when the engine is started making the vehicle
more visible to other users.
This function is assured by special lamps.
The lighting control stalk must be placed in
position "0" or "AUTO" (day mode).
Automatic illumination of headlamps
The sidelamps and the dipped beam headlamps
come on automatically, without any action on the
part of the driver, if a low level of exterior light is
detected or if the wipers are switched on.
When the light returns to a sufficient level or the
wipers are switched off, the lighting is switched off
automatically.
The sensor is located at the base of the windscreen.
Contact a CITROËN dealer or a qualified workshop
to adjust the sensitivity of the sensor.
