COMFORT
The air conditioning system does
not contain chlorine and does not
present any danger to the ozone
layer.
In order for these systems to be fully effective, follow the guidelines on operation
and maintenance below:

 If the interior temperature remains very high after the vehicle has been
parked in the sun for a considerable time, fi rst ventilate the passenger
compartment for a few minutes.
Place the air fl ow control at a suffi cient level t o provide an adequate renewal
of air in the passenger compartment.

 To obtain an even air distribution, take care not to obst ruct the exterior air
intake grilles located at the base of the windscreen, the n ozzles, the vents
and the air outlets, as well as the air extractor located in the passenger
compartment on both sides of the rear shelf.

 Do not cover the sunshine sensor, located on the dashboard (behind the
instrument panel); this is used for regulation of t he air conditioning system.

 Operate the air conditioning system for 5 to 10 minutes, on ce or twice a
month to keep it in good working order.

 Ensure that the passenger compartment fi lter is in good condit ion and
have the fi lter elements replaced regularly (refer to the "Checks" section).
We recommend the use of a combined passenger compartment fi lter.
Thanks to its second special active fi lter, it contributes to t he purifi cation
of the air breathed by the occupants and the cleanliness of the passen-
ger compartment (reduction of allergic symptoms, bad odours and grea sy
deposits).

 To ensure correct operation of the air conditioning system, you are also
advised to have it checked regularly.

 If the system does not produce cold air, do not use it and contact a
CITROËN dealer.
When towing the maximum load on a steep gradient in high temperatures,
switching off the air conditioning saves engine power and so improves towing
capacity.
The condensation created by the air conditioning results in a discharge of
water under the vehicle which is perfectly normal.

VISIBILITY
Vertical windscreen wiper
position
Automatic rain sensitive
windscreen wipers
The windscreen wipers operate auto-
matically, without any action on the part
of the driver, if rain is detected (sensor
behind the rear view mirror), adapting
their speed to the intensity of the rain-
fall.
Activation
This is controlled manually by the driver
by pushing the stalk downwards to the

"AUTO" position.
It is accompanied by a message on the
multifunction screen. This position allows the wiper blades to
be lifted for winter parking, cleaning or re-
placement without damaging the bonnet.
In the minute following switching off of
the ignition, any action on the wiper
stalk positions the wipers vertically.
To park the wipers after this has been
done, switch on the ignition and operate
the wiper stalk.
Do not cover the rain sensor, linked
with the brightness sensor and lo-
cated in the centre of the wind-
screen behind the rear view mirror.
Switch off the automatic rain sensi-
tive wipers when using an automatic
car wash.
In winter, to avoid damaging the
wiper blades, it is advisable to wait
until the windscreen is completely
clear of ice before activating the
automatic rain sensitive wipers. It is accompanied by a message on
the multifunction screen.
The automatic rain sensitive wipers
must be reactivated if the ignition has
been off for more than one minute,
by pushing the stalk downwards.
Switching off
This is controlled manually by the driver
by moving the stalk upwards then re-
turning it to position "0" . Operating fault
If an automatic wiping malfunction oc-
curs, the wipers will operate in intermittent
mode.
Have it checked by a CITROËN dealer.
To retain the effectiveness of the
"fl at-blade" wiper blades, it is advis-
able to:
- handle them with care,
- clean them regularly using soapy water,
- not use them to hold a sheet of cardboard against the wind-
screen,
- replace them at the fi rst signs of wear.

DRIVING
PARKING SENSORS
System comprising four proximity sen-
sors, located in the rear bumper.
This detects any obstacle (person, vehi-
cle, tree, gate, etc.) behind the vehicle.
Nevertheless, it cannot detect obstacles
located just below the bumper. An object, such as a stake, a road-
works cone or any other similar
object may be detected at the be-
ginning of the manoeuvre, but may
no longer be detected when the ve-
hicle comes close to it. Activation
The system is activated as soon as re-
verse gear is engaged, accompanied
by an audible signal. The proximity in-
formation is given by:
- an audible signal, which becomes
more rapid as the vehicle approaches
the obstacle,
- a graphic on the multifunction screen, with blocks which become
increasingly closer to the vehicle. The parking sensors system can-
not, in any circumstances, take the
place of the vigilance and responsi-
bility of the driver.
Detection zone
When the distance between the rear of
the vehicle and the obstacle is less than
thirty centimetres, the audible signal be-
comes continuous and the "Danger" sym-
bol appears on the multifunction screen.
On completion of the manoeuvre, when
you exit reverse gear, the system be-
comes inactive.

(vehicle fi tted with a towbar or bi-
cycle carrier recommended by
CITROËN). Reactivation
Press button
A again to reactivate the
system. The indicator lamp on the but-
ton is switched off.
If there is an operating fault, when re-
verse gear is engaged, the service
warning lamp comes on, accompanied
by an audible signal (short beep) and a
message on the multifunction screen.
With the engine running, press button A to
deactivate the system permanently. The
indicator lamp on the button comes on. In bad or wintry weather, ensure
that the sensors are not covered
with mud, frost or snow.

PRACTICAL INFORMATION
TOWING A TRAILER, A CARAVAN, ETC.
Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer. Driving advice
The maximum towing load on a long
slope depends on the gradient and the
ambient temperature.
In all cases, pay attention to the coolant
temperature.
Side wind

 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.

 To lower the engine speed, reduce
your speed. Braking
Towing a trailer increases the braking
distance.
Tyres

 Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended pres-
sures.
Lighting

 Check the electrical lighting and
signalling on the trailer.
The rear parking sensors will be de-
activated automatically if a genuine
CITROËN towbar is used.
 If the warning lamp and the

STOP warning lamp come
on, stop the vehicle and
switch off the engine as
soon as possible.
Towbar suitable for the attachment of a
trailer or caravan with additional lighting
and signalling.
Distribution of loads

 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 performance. Above
1 000 metres, the maximum towing load
must be reduced by 10 % 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.
Driving with a trailer subjects the towing
vehicle to more signifi cant stress and its
driver must be particularly careful.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
of your vehicle, and that the fi t-
ting of the towbar is entrusted to a
CITROËN dealer.
If the trailer is not fi tted by a
CITROËN dealer, it is imperative
that it is fi tted using the electrical
pre-equipment installed at the rear
of the vehicle, in accordance with
the manufacturer's instructions.
