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 g uidelines on opera-
tion 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 to provide an adequate re-
newal 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 compa rtment fi lter. Thanks
to its second special active fi lter, it contributes to the purifi cation of the air
breathed by the occupants and the cleanliness of th e passenger compart-
ment (reduction of allergic symptoms, bad odours an d greasy 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.

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 towed load on a long
incline depends on the gradient and the
ambient temperature.
In all cases, keep a check on 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
deactivated automatically if a gen-
uine 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 towed load
must be reduced by 10 % for every
1 000 metres of altitude.
Refer to the "Technical Data" section for
details of the weights and towed loads
which apply to your vehicle.
Driving with a trailer subjects the towing
vehicle to more signifi cant stress and
the driver must take particular care.
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 vehicle's electrical pre-
equipment, in accordance with the
manufacturer's instructions.
