Ventilation
DE-ICING AND DEMISTING
Windscreen
The ventilation outlets located at the base
of the windscreen and the side vents for the
side windows increase the effectiveness of
the de-icing and demisting. Do not obstruct
these eight air outlets.
The manual air conditioning consists of the
pollen filter and air recirculation.
The pollen filter permits continuous and
effective filtering of dust.
The air recirculation (which can be activated
by the driver or the passenger) isolates the
passenger compartment from the exterior
atmosphere. However, this position should
only be used temporarily, the norm is to
drive with the control positioned with the
exterior air intake open.
Manual mode
Direct the control to this air
distribution setting.
For faster and more effective
de-icing and demisting of the
windscreen: - increase the air flow setting,
Returning to the exterior air intake
position permits renewal of the air
in the passenger compartment.
Rear screen and mirrors de-icing
This function only operates when
the engine is running. Pressing
this button activates the rapid
demisting/de-icing of the rear
screen and mirrors. This function switches
off automatically to prevent an excessive
consumption of energy. It switches off when
the engine is switched off. Pressing this
button switches the function off.
- move the exterior air intake
control temporarily to air
recirculation.

Ventilation
These controls are located on the centre console.
Air conditioning
The air conditioning mode is operational
when the engine is running. The diode is lit.
Temperature adjustment
Control positioned:
- in the blue zone triggers cool
air,
Air fl ow
The force of the blown air, from
the vents, varies from 1 to the
strongest 4 . Remember to adjust
this control in order to reach the
ambient air comfort level. To switch off the
blower, place the control in position 0 .
The air supply distribution is
directed by the control turned
towards:
the side vents and the central
vents,
the side vents, the central vents
and the footwells,
the footwells,
the windscreen, the front side
windows and the footwells,
the windscreen.
Press the air blower control. The
diode lights.
The air blower control must not
be in position
0 (zero flow) for air
conditioning to be obtained.
Turn the control to the position required. - in the red zone triggers heating
of the interior ambient air.

ACCESSORIES
Towing a trailer
TOWING A TRAILER, CARAVAN, BOAT, ETC.
Driving advice
A towed vehicle must free wheel: gearbox in
neutral.
Cooling: towing a trailer on a slope
increases the coolant temperature.
As the fan is electrically controlled, its
cooling capacity is not dependent on the
engine speed.
On the contrary, use a high gear to lower the
engine speed and reduce your speed.
In all cases, pay attention to the coolant
temperature.

102
Towing a trailer
In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this
case, the automatic cutting off of the air
conditioning allows the engine power to be
recovered.
If the coolant temperature
warning light comes on, stop the
vehicle and switch off the engine
as soon as possible.
See the "Levels" section of chapter 7.
Tyres: check the tyre pressures of the
towing vehicle (see the "Identification
features" section of chapter 7) and of
the trailer, observing the recommended
pressure.
Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake gradually.
Side wind: sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.
ABS: the system only controls the vehicle,
not the trailer.
Rear parking assistance:
the assistance will be deactivated
automatically when a CITROËN towbar is
used (see the "Rear parking assistance"
section of chapter 4).
Towbar
We recommend the use of CITROËN
towbars and their harnesses, which have
been tested and approved from the design
stage of your vehicle, and that the fitting of
this equipment is entrusted to a CITROËN
dealer .
If this equipment is not fitted by a CITROËN
dealer , it is essential that it is fitted using
the electrical pre-equipment located at the
rear of the vehicle in accordance with the
manufacturer ’s instructions.
The operation of the sensors is deactivated
automatically when the pin of the trailer
cable is inserted in the towbar socket.
When the trailer cable pin is removed, the
sensors are re-activated.
Distribution of loads
Distribute the load in the trailer so that the
heaviest objects are as close as possible
to the axle and the nose weight is close to
the maximum authorised without, however,
exceeding it. The air density decreases with
altitude, so reducing the performance of
the engine. The maximum towed load must
be reduced by 10 % for each 1 000 metres
of altitude. Refer to the "Technical data"
chapter for details of the weights and towed
loads applicable to your vehicle and also to
the administrative documents
(V5 registration document, etc.).

TROUBLESHOOTING
Battery
BATTERY

A. Positive metal point on your vehicle

B. Slave battery

C. Earth on your vehicle
CHARGING THE BATTERY USING A CHARGER
- disconnect the battery,
- follow the instructions for use given by
the battery charger manufacturer,
- reconnect starting with the negative (-) terminal,
- check that the terminals and connectors are clean. If they are covered with
sulphate (white or greenish deposit),
disconnect them and clean them. The charging operation must be carried
out in a ventilated area away from naked
fl ames or any possible sources of sparks to
eliminate the risk of explosion and fi re.
Do not attempt to charge a frozen battery: it
must first be thawed to eliminate the risks of
explosion. If the battery has frozen, before
charging it have it checked by a specialist
who will check that the internal components
have not been damaged and that the
container is not cracked, which could mean
that there is a risk of a leak of toxic and
corrosive acid.
STARTING FROM ANOTHER BATTERY
- connect the red cable to the metal point
A then to the positive (+) terminal of the
slave battery B ,
- connect one end of the green or black cable to the negative (-) terminal of the
slave battery B ,
- connect the other end of the green or black cable to the earth point C on your
vehicle,
- operate the starter, let the engine run,
- wait for the engine to return to idle, then disconnect the cables.

106
Battery
The batteries contain harmful
substances such as sulphuric acid and
lead. They must be discarded in accordance
with the provisions of the law and must not,
in any circumstances, be discarded with
household waste.
Take used batteries to a special collection
point.
Before disconnecting the battery, you must
wait for 2 minutes after switching off the
ignition.
Never disconnect a terminal when the
engine is running.
Never charge a battery without first
disconnecting the terminals.
Close the windows and doors before
disconnecting the battery.
After every reconnection of the battery,
switch on the ignition and wait 1 minute
before starting to allow the electronic
systems to be initialised. If slight difficulties
are experienced after this, please consult a
CITROËN dealer . It is advisable to disconnect the battery
if the vehicle is not to be used for a
period of more than one month.
If the battery has been disconnected
for some time, it may be necessary to
reinitialise the following functions:
- the display parameters (date, time, language, distance unit and temperature
unit),
- the radio stations,
- the central locking.
Some settings are cleared and must be
reprogrammed, consult a CITROËN dealer .
