Driving





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 chan
ge transmission mode when stationary or while driving.
The transmission mode can be selected byturning 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
mana
ged 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 par ticularly
poor or di
fficult (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 riskof loss of grip (dry road).
Display in the instrument panel
The transmission mode is displayed in the
form of an intermittent display in the instrumentpanel screen when the transmission mode is
selected.
The selection of this mode isrecommended when the level of grippermits.

Driving
As the engine torque is applied to all four wheels, the condition of the tyres
has a considerable impact on theperformance 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 whichthe wheels could spin. Spinning the wheels places thetransmission components under pressure and could cause a seriousmalfunction. Do not drive the vehicle through deep water. Avoid driving over excessively uneventerrain (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 displa
y to clear beforesetting off again.
If "4WD" and "LOCK" are displayed alternatelyand 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 dela
y.
Have your vehicle towed on a flatbed. The vehicle must not be towed with the front or rear wheels on the ground evenif it is in front "2WD" (2 wheel drive)mode.

Technical data
Caution, towing with a lightly loaded towing vehicle can have an adverse affect on its roadholding.
The GTW and towed load values indicated are valid up to a maximum altitude of 1 000 metres; the towed load mentioned must be reduced by 10 % for each additional 1 000 metres of altitude.
The speed of a towing vehicle must not exceed 60 mph (10 0 km/h) (comply with the legislation in force in your country).
High ambient temperatures may result in a reduction in the performance of the vehicle to protect the engine; if the ambient temperature is above 37 °C, limit the towed load.
