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.

Cruise control
System which automatically maintains the vehicle speed at the value programmed by the driver, without any action on the accelerator pedal.
The cruise control is switched on manually:
the vehicle speed must be at least 25 mph
(40 km/h) and second gear or higher must be
engaged in the case of a manual gearbox.
The cruise control is switched off manually, by
an action on the brake or clutch pedal or if the
ASC system is triggered.
The programmed speed can be exceeded
temporarily by pressing the accelerator pedal.
The cruise control cannot, in any
circumstances, take the place of the
need to comply with speed limits or of the
vigilance and responsibility of the driver. The controls of this system are grouped
together on the steering wheel.

Visual assistance
Front parking sensors
Deactivation / Activation of the
front and rear parking sensors
The function is deactivated by pressing this
button. The indicator lamp in the button
goes off.
Pressing this button again reactivates the
function. The indicator lamp in the button
comes on.
Operating fault
The front parking sensors are triggered when
an obstacle is detected in front, a gear is
engaged (position D for vehicles with a CVT
gearbox) and the speed of the vehicle remains
below 6 mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than five seconds
in for ward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h). Remember to deactivate the system if
towing a trailer or caravan.In bad weather or in winter, ensure that
the sensors are not covered with mud,
ice or snow.
When the vehicle is moving at a speed
below 6 mph (10 km/h), certain sound
sources (motorcycle, lorry, pneumatic
drill, etc.) may trigger the audible
signals of the parking sensor system.
In the event of an problem, when reverse gear
is engaged this lamp in the button flashes,
accompanied by an audible signal.
This supplements the audible
signal by displaying bars in the
screen, in front of or behind
the vehicle.
If one of the sensors is faulty, it
flashes in the instrument panel
screen.
Contact a CITROËN dealer or a qualified
workshop.
These bars flash at the start of the manoeuvre
then become fixed from a certain distance
between the vehicle and the obstacle.

Reversing camera
Linked with the navigation option, the reversing
camera complements the parking sensor
system and is activated automatically when
reverse gear is engaged.The image from the camera is displayed in the
navigation screen.
The zone (A)


represents the upper part of the
rear bumper.
The red line represents the distance of 50 cm
from the edge of the rear bumper.
The green lines represent the width of the
vehicle increased by 20 cm on each side.
The marks on the green lines correspond to the
edges of the rear bumper (B), then the distance
of 1 metre from the edge of the rear bumper (C)
and 2 metres (D) . In no circumstances can the reversing
camera replace the need for vigilance
on the part of the driver.
Clean the reversing camera from time
to time using a soft dry cloth.
High pressure jet wash
When washing your vehicle, do not
direct the lance to within 30 cm of the
camera lens.

Driving advice
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches the
maximum permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine per formance. Above
1
000 metres, the maximum towing load must
be reduced by 10
% of the GTW and so on for
every 1
000 metres of altitude.
Refer to the "Technical Data" section for details
of the weights and towing loads which apply to
your vehicle.
Side wind
F Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towing load on a long slope
depends on the gradient and the outside
temperature.
In all cases, pay attention to the coolant
temperature.
F

I
f this message is displayed, stop your
vehicle as soon as it is safe to do so.
Braking
Towing a trailer increases the braking distance.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the lighting and signalling on the trailer.
If the message flashes slowly, wait for the
engine to cool before topping up the level, if
necessary.
If the message flashes rapidly, contact a
CITROËN dealer or a qualified workshop
without delay.
