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.
