Ventilation
De-icing the rear screen and/or
mirrors
Pressing this button, with the engine
running, activates the rapid demisting -
de-icing of the rear screen and/or electric
mirrors.
This function switches off:
- when the button is pressed,
- when the engine is switched off,
- automatically to prevent excessive energy consumption. Automatic air conditioning: visibility
programme
The comfort programme (AUTO) may not
be sufficient to quickly demist or de-ice the
windows (humidity, several passengers, ice).
In this case, select the visibility programme.
The visibility programme indicator light
comes on.
It activates the air conditioning, the air flow,
the de-icing of the rear screen and provides
optimum distribution of the ventilation to the
windscreen and side windows.
It deactivates the air recirculation.

Ventilation Good practice
To avoid any risk of poisoning or
asphyxiation, the heater must not be used,
even for short periods, in an enclosed space
such as a garage or workshop which is not
fitted with an exhaust gas extraction system.
Do not park the vehicle on an inflammable
surface (dry grass, dead leaves, paper…),
there is a risk of fire.
The temperature near the heater must not
exceed 120 °C. A temperature higher than this (for example
in the case of painting in an oven) could
damage the components of the electronic
circuits.
The heater is supplied by the vehicle’s fuel
tank. Ensure that the fuel gauge indicator
light is not at reserve.
ADDITIONAL HEATING
Coolant circuit heater
This is an additional and autonomous
system which heats the diesel engine hot
coolant loop to make starting easier.
It improves the de-icing and demisting
performance.
Vehicles fitted with an HDi engine may be
fitted with a heater. When the engine is at
idle or the vehicle is stationary, it is normal
to notice a high-pitched whistling noise and
a slight emission of smoke and odour.

Driving safety
SAFETY
5
TRACTION CONTROL (ASR) AND DYNAMIC STABILITY CONTROL (ESP)
These systems are linked and complement
the ABS.
The ASR system is very useful for
maintaining optimum drive and avoiding
losses of control of the vehicle on
acceleration.
The system optimises drive to prevent the
wheels skidding, by acting on the brakes of
the drive wheels and on the engine. It also
allows the directional stability of the vehicle
to be improved on acceleration. acts on the engine and the brake of one
or more wheels, in order to put the vehicle
back on course.
Disarming the ASR/ESP systems
In certain exceptional conditions (starting
the vehicle when stuck in mud or snow, or
on loose ground...), it could prove useful to
disarm the ASR and ESP systems to make
the wheels spin and regain grip.
- Press the button, located on the centre
console.
- The indicator light comes on: the ASR and ESP systems no longer act. Operating check
Good practice
The ASR/ESP systems offer increased
safety during normal driving, but should not
incite the driver to take risks or to drive at
high speed.
The operation of these systems is ensured
if the recommendations of the manufacturer
regarding the wheels (tyres and rims),
the braking components, the electronic
components and the fitting and repair
procedures within the CITROËN network are
observed.
After an impact, have these systems
checked by a CITROËN dealer.
Use the ESP to hold your course without
attempting to countersteer.
If there is a variation between the trajectory
followed by the vehicle and that required
by the driver, the ESP system automatically Operation of the ASR and ESP
systems
The luminous diode flashes when
the ASR or ESP is triggered.
They engage again:
- automatically above 30 mph (50 km/h),
- manually by pressing the button again. When a malfunction of the
systems occurs, the indicator light
comes on, accompanied by an
audible signal and a message on
the display.
Contact a CITROËN dealer to have the
system checked.
The warning light may also come on if the
tyres are under-inflated. Check the pressure
of each tyre.

Towing a trailer
ACCESSORIES

For more information about weights,
refer to the administrative documents
(V5 registration document, ...) or to the
"Weights" section of chapter 9.
TOWING A TRAILER, CARAVAN, BOAT, ETC...

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.
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.
Driving advice
A towed vehicle must free wheel: gearbox in
neutral.

140
Towing a trailer
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. Tyres: check the tyre pressures of the
towing vehicle (see the "Identification
features" section of chapter 9) and of
the trailer, observing the recommended
pressure. 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
you entrust the fitting of this equipment to a
CITROËN dealer.
If this equipment is not fitted by a CITROËN
dealer, it is imperative that it is fitted using
the electrical pre-equipment installed at the
rear of the vehicle and in accordance with
the manufacturer ’s instructions.
In accordance with the general instructions
a reminder of which has been given above,
we draw your attention to the risk linked with
fitting a towbar or electrical accessory not
recommended by CITROËN . Fitting such
equipment could result in the failure of your
vehicle’s electronic system. Please contact
a CITROËN dealer for information before
fitting this type of equipment.
See the "Levels" section of chapter 7.
Good Practice
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.
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/ESP
The ABS or ESP systems only control the
vehicle, not the trailer or caravan.

Rear parking assistance
The assistance does not function while the
vehicle is towing.

OPENING THE BONNET

From inside:
- lift the cover located at the left foot of the passenger ’s seat.
- pull the control upwards. To close
Lower the bonnet and release it at the end of its
travel. Check that the bonnet is properly locked.

From outside: partially open the bonnet, lift
the catch and raise the bonnet.
Bonnet strut
Secure the strut in one of the two notches,
according to the height required, to hold the
bonnet open.
Before closing the bonnet, replace the strut
in its housing. "Bonnet open" warning
This warning is linked to the
alarm option
only.
With the engine running or the
vehicle moving, a warning light
and a diagram on the display,
accompanied by an audible
signal, warn you that the bonnet is not
properly closed.
