Air conditioning
We recommend use of the automatic
regulation of the air conditioning.
It permits automatic and optimised
control of all of the following func-
tions: air fl ow, temperature in the
passenger compartment and air
distribution, by means of various
sensors (exterior temperature, sun-
shine). This eliminates any need for
you to change your settings other
than the temperature value dis-
played.

 Please do not block the sunshine
sensor A .
If you select the automatic mode (by
pressing the "AUTO" control) and
leave all of the vents open, optimum
comfort will be maintained and humid-
ity and condensation will be removed
regardless of the exterior climatic con-
ditions.
The temperature in the passenger
compartment can only be lower than
the exterior temperature if the air
conditioning is on.
VENTILATION, HEATING AND AIR CONDITIONING RECOMMENDATIONS
In order to be effective, the air condi-
tioning must be used with the windows
closed. If the vehicle has been parked
in the sun for a long period and the in-
terior temperature is very high, venti-
late the passenger compartment with
the windows open for a few minutes,
then close the windows.
To keep the air conditioning system
in good working order it is essential
that it is operated at least once a
month.
The air conditioning uses the engine
power during its operation. As a result,
the fuel consumption of the vehicle in-
creases.
In certain cases of particularly ardu-
ous use (e.g. towing the maximum
load on a steep gradient in high tem-
peratures), switching off the air condi-
tioning permits the recovery of engine
power and therefore increases the
towing capacity.
Air inlet
Check that the exterior grille for the
air inlet, at the bottom of the wind-
screen, is clean and free of dead
leaves, snow, etc.
When washing the vehicle using a
high pressure nozzle, avoid spray-
ing at the air inlet. Air circulation
Maximum comfort is obtained by
means of a good distribution of air in
the passenger compartment, both in
the front and in the rear.
To obtain a uniform distribution of
air, take care not to block the ex-
terior air intake grille located at the
base of the windscreen, the vents,
the air outlets under the front seats
and the air extractor located behind
the fl aps in the boot.
The front and rear vents are fi tted
with thumbwheels to adjust the air
fl ow and direction. We recommend
that you leave all of the vents open.
Dust filter/Odour filter
(active carbon)
There is a fi lter for excluding odours
and dust.
This fi lter has to be changed in ac-
cordance with the vehicle mainte-
nance schedule (see: "Maintenance
and Warranty Guide").

TOWING A TRAILER, A CARAVAN, ETC.
Towbar suited to the attachment of a
trailer or caravan with additional sig-
nalling and lighting.
Your vehicle is primarily designed
for transporting people and luggage,
but it may also be used for towing a
trailer.
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 manufactur-
er’s instructions.
Driving with a trailer subjects the
towing vehicle to more signifi cant
stress and its driver must be par-
ticularly careful.
Driving advice
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 ex-
ceeding 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.
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.
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.

 If the warning lamp and
the STOP warning lamp
come on, stop the vehicle
and switch off the engine
as soon as possible.
Braking
Towing a trailer increases the brak-
ing distance.
Tyres

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

 Check the electrical signalling on
the trailer.
The rear parking assistance will
be deactivated automatically if an
original CITROËN towbar is used.
