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
CORRECT USE OF THE AIR CONDITIONING
In order to be effective, the air conditioning
should only be used with the windows
closed. However, if the interior temperature
remains high after a prolonged period
parked in the sun, do not hesitate to
ventilate the passenger compartment for a
few minutes. For even air distribution, ensure that the
exterior air intake grille located at the base
of the windscreen is not obstructed and that
the side and central vents, the air outlets on
the floor and the air extractor at the rear are
open.
The air conditioning is useful in all seasons
as it eliminates condensation and air
humidity. Operate the air conditioning system for
5 to 10 minutes, once or twice a month,
to keep it in perfect working order.
Have the filter elements (air filter and
passenger compartment filter) replaced
regularly. If you drive in a dusty environment,
have them replaced twice as often.
It is normal that the condensation created by
the air conditioning system results in a flow
of water which may form a puddle under the
vehicle when parked.
If the system does not produce cold air, do
not use it and contact a CITROËN dealer . VENTS
For optimum distribution and diffusion of hot
or cool air in the passenger compartment,
there are:
- 2 adjustable central vents,
- 2 adjustable and closing side vents,
- 2 vents directed towards the floor of the vehicle.

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.

ERGONOMICS and COMFORT
Ventilation
Intake of exterior air
This is the preferred operating
position.
Recirculation of interior air
This position should only be
temporary.
Used with the air conditioning
switched on and setting of the
force of blown air (from 1 to 4), recirculation
enables you to obtain the required ambient
air comfort level with both hot or cold
settings.
Recirculation temporarily prevents exterior
odours and smoke from entering the
passenger compartment. De-icing is more
rapid in this position.
When your ambient air comfort level has
been reached, return to the intake of exterior
air position to permit renewal of the air in the
passenger compartment and demisting. This
operating mode is preferable.

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, ...).

CHECKS

Bleeding the water contained in the
diesel filter
If this warning light comes on,
bleed the filter, otherwise bleed
regularly each time the engine is
drained.
To evacuate the water, unscrew the bleed
screw or the water in diesel sensor, located
at the base of the filter. Operate until all
of the water has been drained out. Then
tighten the bleed screw or the water sensor.
HDi engines use advanced technology. All
work requires a special qualification which is
guaranteed by a CITROËN dealer .

Battery
At the start of winter, have it checked by a
CITROËN dealer .
Air fi lter and passenger compartment fi lter
A clogged passenger compartment filter
may reduce the performance of the
air conditioning system and generate
undesirable odours. The replacement
intervals for these components are indicated
in the servicing booklet.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary, refer to the "Under the
bonnet" section of chapter 7.

Brake pads
Brake pad wear depends on the style of
driving, in particular for vehicles which are
used in town, over short distances. It may
be necessary to check the thickness of the
pads, even between services.
Unless there is a leak on the circuit, a drop
in the brake fluid level indicates that the
brake pads are worn.

Brake disc/drum wear status
For any information relating to checking
the brake disc/drum wear status, consult a
CITROËN dealer .
Handbrake
Where the handbrake travel is too great
or there is a reduction in the performance
of the system, the handbrake should be
adjusted, even between services.
Have it checked by a CITROËN dealer .

Oil filter
Change the filter regularly, in accordance
with the servicing schedule.
Manual gearbox
Have the level checked in accordance with
the manufacturer ’s servicing schedule.
To check the main levels and certain
components, in accordance with the
manufacturer ’s servicing schedule, refer
to the pages of the servicing booklet which
correspond to your vehicle’s engine.
Only use products recommended by
CITROËN or products of equivalent quality
and characteristics.
In order to optimise the operation of units as
important as the braking circuit, CITROËN
selects and offers specific products.
In order to avoid damaging the electrical
units, high pressure washing to clean the
engine compartment is strictly prohibited.
