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.
With Stop & Start, when the heated
rear screen is switched on, the STOP
mode is not available.

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 flow
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,

Driving safely
Emergency braking assistance *
System which, in an emergency, enables
you to reach the optimum braking pressure
more quickly, thus reducing the stopping
distance. The emergency braking assistance
is an integral part of the ESP system
Activation
It is brought into play by the speed at which
the brake pedal is pressed.
The effect of this is a reduction in the
resistance of the pedal and an increase in
braking efficiency.
When braking in an emergency, press firmly
without releasing the pressure.
Good practice
This system cannot be deactivated by the
driver.
* Depending on country of sale.
TRAJECTORY CONTROL SYSTEMS
Electronic stability programme (ESP)
The electronic stability programme acts on
the brake of one or more wheels and on the
engine to keep the vehicle on the trajectory
required by the driver, within the limits of the
laws of physics.
Activation
The ESP system is activated automatically
each time the vehicle is started and cannot
be deactivated.
It comes into operation in the event of a grip
or trajectory problem.
Illumination of this warning lamp
and the warning lamp in the

"ASR OFF" button, accompanied
by a message in the instrument
panel screen, indicates a fault with the ESP
system, which is deactivated automatically.
Have it checked by a CITROËN dealer. Anti-slip regulation (ASR) and engine
control (MSR)
Anti-slip regulation (also known as traction
control) optimises traction, avoiding wheel
spin by acting on the brakes of the driving
wheels and the engine.
Engine control is an integral part of the ASR
system and intervenes when a sudden gear
change is made or of one of the driving
wheels looses grip, by reducing engine
torque to avoid loss of stability of the vehicle.
Activation
These systems are activated automatically
every time the vehicle is started.
In the event of a problem od adhesion or
trajectory, these systems come into play.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow,
on soft ground...), it may be advisable to
deactivate the ASR system, so that the
wheels can spin freely and regain grip.

 Press the "ASR OFF" button, located in
the middle of the dashboard.
If the button's warning lamp comes
on, accompained by a message in the
instrument panel screen, this indicates that
the ASR system is deactivated.
This is indicated by flashing of this
warning lamp in the instrument
panel.

SAFETY
Seat belts
FRONT SEAT BELTS
The front seats are fitted with pre-tensioners
and force limiters.
Fastening
Pull the strap, then insert the tongue into the
buckle.
Check that the seat belt is fastened correctly
by pulling the strap.
The lap belt must be positioned as low as
possible on the pelvis. The chest belt must
pass over the hollow of the shoulder. Inertia reel seat belts
These are fitted with a device which locks
automatically in the event of a collision or
emergency braking.
Safety in the event of a front impact has
been improved by the introduction of
pretensioning and force limiting seat belts.
Depending on the seriousness of the
impact, the pretensioning system instantly
tightens the seat belt against the body of the
occupant.
The pretensioning seat belts are active when
the ignition is on.
The force limiter reduces the pressure of the
seat belt against the body of the occupant in
the event of an accident. Driver's seat belt not fastened warning
lamp
When the vehicle is started, this
warning lamp comes on if the
driver has not fastened their seat
belt.
REAR SEAT BELTS (COMBI)
The 3-seat bench is fitted with three-point
inertia reel seat belts with force limiter.
The centre seat has a seat belt guide and
inertia reel, integrated with the seat back.
When a seat belt is not in use, you can
store its buckle in the housing provided
in the bench seat cushion.
if the driver's seat belt is unfastened,
the START mode of Stop & Start will
not be invoked. The engine can only be
restarted using the ignition key.

Towing a trailer
TOWING A TRAILER, CARAVAN, ETC...
Driving advice 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.
A towed vehicle must free wheel: gearbox in
neutral.

Cooling: towing a trailer on a slope
increases the coolant temperature.

ACCESSORIES
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,
automatic cutting off of the air conditioning
allows the engine power to be saved.
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
markings" section of chapter 7) and of
the trailer, observing the recommended
pressures.

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 sensors: the sensors
will be deactivated automatically
when an genuine CITROËN towbar is used
(see the "Rear parking sensors" section of
chapter 3). Towbar
We recommend the use of original
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 and following the
manufacturer's instructions.
The operation of the rear parking sensors is
deactivated automatically when the trailer
cable connector is inserted in the towbar
socket.
When the trailer cable is removed, the rear
parking 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, ...).
