In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:
F
T
o obtain an even air distribution, take care not to obstruct the exterior air intake grilles
located at the base of the windscreen, the nozzles, the vents and the air outlets, as well
as the air extractor located in the boot.
F

D
o not cover the sunshine sensor, located on the dashboard; this is used for regulation
of the air conditioning system.
F

O
perate the air conditioning system for at least 5 to 10 minutes, once or twice a month
to keep it in per fect working order.
F

E
nsure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly.
W

e recommend the use of a combined passenger compartment filter. Thanks to its
special active additive, it contributes to the purification of the air breathed by the
occupants and the cleanliness of the passenger compartment (reduction of allergic
symptoms, bad odours and greasy deposits).
F

T
o ensure correct operation of the air conditioning system, you are also advised to have
it checked regularly as recommended in the maintenance and warranty guide.
F

I
f the system does not produce cold air, switch it off and contact a CITROËN dealer or a
qualified workshop.
Recommendations for ventilation and air conditioning
If after an extended stop in sunshine,
the interior temperature is very high, first
ventilate the passenger compartment for
a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
The air conditioning system does not
contain chlorine and does not present
any danger to the ozone layer.
The condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
per fectly normal.
When towing the maximum load on a steep gradient in high temperatures, switching off the
air conditioning increases the available engine power and so improves the towing ability.

Manual heating / air conditioning
The system operates with the engine running.
1. Temperature setting
F Turn the temperature control dial to the right to raise the
temperature, and to the left to
lower it.
To avoid misting and deterioration of the air
quality in the passenger compartment, ensure
that an adequate air flow is maintained.
3. Air distribution setting
F Place the dial in the desired position, to direct air towards:
t

he centre and side vents,
The air distribution can be modulated by
placing the dial in intermediate positions.
2. Air flow setting

Switching to manual mode may result in
discomfort (temperature, humidity, odour,
condensation) and does not offer optimum
comfort.

Manual gear changing
In the automated mode, you can take over
control temporarily at any time using the
steering mounted controls.
The use of these controls permits manual
selection of the gears in situations which
require a faster change down than that offered
in automated mode (arrival at a roundabout,
exit from a car park with a steep gradient,
over taking...).
The gearbox engages the gear requested if
the engine speed permits it. The gear engaged
appears.
To return to the automated mode, do one of the
following:
-
p
ress the back of the "+/OFF" steering
mounted control 3 for approximately
2
seconds,
-

m
ove the gear lever quickly towards
position +/- and then return it to position D ,
-

s
top the vehicle.
Stopping the vehicle Operating fault
With the ignition on, if the message "Slow
down" or "Service required" appears in
the instrument panel screen, this indicates a
gearbox malfunction.
When a message is displayed, carry out the
following operations:
-

s
low down and stop your vehicle in a safe
place,
-

p
lace the lever in position P and let the
engine run,
-

o
pen the bonnet to allow the engine to
cool.
If the message disappears for a long period,
you can set off again.
If the message remains displayed or appears
frequently, contact a CITROËN dealer or a
qualified workshop without delay.
Before switching off the engine, you must place
the gear lever in position P
.
You must apply the parking brake to immobilise
the vehicle.
Driving

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.
