To avoid the risks of poisoning or
asphyxia, the additional heating must
not be used, even for short periods, in
a closed environment such as a garage or
workshop which are not equipped with an
exhaust gas extraction system.
The additional heating switches off when
the battery voltage is low, so as to allow
engine starting.
The additional heating is fed by the
vehicle's fuel tank. Ensure that the low fuel
warning lamp is not on.
Always switch off the additional heating
when refuelling to avoid any risk of fire or
explosion!
The temperature near the heating
system must not exceed 120°C. A higher
temperature (e.g. when baking the
paint) could damage the components of
electronic circuits.
The additional heating is fitted with
a
temperature limiter which cuts off
the combustion in the event of engine
overheating due to a
lack of coolant.
Check the level and top up if necessary.
For more information on Checking levels ,
refer to the corresponding section.
Then press the programme selection
button before switching the heating on
again.Recommendations for ventilation and air conditioning
In order for these systems to be fully effective,
follow the operation and maintenance
guidelines below:
F

T
o ensure that the air is distributed evenly,
keep the external air intake grilles at the
base of the windscreen, the nozzles, the
vents, the air outlets and the air extractor
in the boot free from obstructions.
F

D
o not cover the sunshine sensor,
located on the dashboard; this is used for
regulation of the automatic air conditioning
system.
F

O
perate the air conditioning system for
at least 5
to 10 minutes once or twice
a
month to keep it in per fect working order.
F

E
nsure that the passenger compartment
filter is in good condition and replace
the filter elements periodically. We
recommend the use of a
combined
passenger compartment filter. Thanks to
its special active additive, it helps both to
purify the air breathed by the occupants
and to keep the passenger compartment
clean (reduction of allergic symptoms, bad
odours and greasy deposits). F
T o ensure correct operation of the
air conditioning system, you are also
advised to have it checked regularly as
recommended in the Maintenance and
Warranty Guide.
F

I
f the system does not produce cold air,
switch it off and contact a
CITROËN
dealer or a
qualified workshop.
When towing the maximum load on a
steep
gradient in high temperatures, switching off
the air conditioning increases the available
engine power and so improves the towing
ability.
To avoid the windows misting up and
deterioration in the quality of the air:
-

d
o not drive for too long with the
ventilation switched off.
-

d
o not keep air recirculation set for an
extended period.

If after an extended stop in sunshine, the
interior temperature is very high, first air
the passenger compartment for a few
moments.
Put the air flow control at a
setting high
enough to quickly change the air in the
passenger compartment.
The condensation created by the air
conditioning results in a
discharge of
water under the vehicle which is per fectly
normal.

Electronic stability control
(ESC)
Electronic stability control (ESC) integrating the
following systems:
-

a
nti-lock braking system (ABS) and
electronic brake force distribution (EBFD),
-
em

ergency braking assistance (EBA),
-

w
heel anti-slip regulation (ASR) or traction
control,
-
d

ynamic stability control (DSC).
Horn
F Press the central part of the steering wheel.
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking
and contributes towards improved control on
corners, in particular on poor or slippery road
surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
(EBFD) manages the braking pressure wheel
by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system permits the
optimum braking pressure to be reached
more quickly, therefore reducing the stopping
distance.
It is triggered in relation to 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.
Anti-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.
Safety

69
Dynamic stability control (DSC)
If there is a difference between the path
f ollowed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
If this warning lamp comes on,
accompanied by an audible signal
and a
message in the instrument
panel screen, it indicates a
fault with
the anti-lock braking system (ABS)
which could result in loss of control
of the vehicle when braking.
If these warning lamps come on,
accompanied by a
message in the
instrument panel screen, it indicates
a
fault with the electronic brake force
distribution (EBFD) system which
could result in loss of control of the
vehicle when braking.
You must stop as soon as it is safe to do so.
In both cases, contact a
CITROËN dealer or
a


qualified workshop. For maximum braking efficiency, a
bedding-in period of around 310
miles
(500 kilometres) is needed. During this
period, it is advisable to avoid any sudden,
repeated and prolonged braking.
The ABS does not provide shorter braking
distances. On very slippery sur faces (ice,
oil, etc.) the ABS may extend braking
distances.
When changing wheels (tyres and rims),
make sure that these are approved for
your vehicle.
For emergency braking, press the
brake pedal ver y hard and do not
release it, even on a
slipper y sur face;
you will then be able to continue
steering the vehicle to avoid an
obstacle.
After an impact, have these systems
checked by a
CITROËN dealer or
a


qualified workshop.
Dynamic stability control
(DSC)
Switching on
The DSC system is activated automatically
each time the vehicle is started.
It comes into operation in the event of a grip or
trajectory problem.
This is indicated by this warning
lamp flashing in the instrument
panel.
Deactivation
This system cannot be deactivated by the
driver.
Malfunction
Illumination of this warning lamp,
accompanied by an audible signal
and confirmed by a message in the
instrument panel screen, indicates
a
fault with the DSC system.
Have it checked by a
CITROËN dealer or by
a


qualified workshop.

AirbagsThe airbags do not operate when the
engine is not running.
This equipment will only deploy once. If
a second impact occurs (during the same
or a
subsequent accident), the airbag will
not be deployed again.
The airbags have been designed to optimise
the safety of the occupants in the event of
a

serious collision; they work in conjunction
with the force limiting seat belts.
In the event of a

serious collision, electronic
detectors record and analyse any abrupt
deceleration of the vehicle:
-

i

n the event of a

serious collision, the
airbags are deployed instantly and
contribute towards better protection of
occupants of the vehicle; immediately after
the impact, the airbags deflate rapidly so as
not to hinder visibility or a

potential exit by
the occupants,
-

i

n the case of a

minor or rear impact or in
certain rollover conditions, the airbags are
not deployed; the seat belt alone contributes
towards ensuring your protection in these
situations. Deployment of the airbags is accompanied
by a
slight discharge of smoke and
a
noise, resulting from activation of the
pyrotechnic charge incorporated in the
system.
Although this smoke is not harmful,
sensitive individuals may experience slight
irritation.
The noise of the detonation may result in
a
slight loss of hearing for a short time.
Front airbags
System which protects the driver and
passenger(s) in the event of a serious front
impact in order to limit the risk of injury to the
head and thorax.
The driver's airbag is fitted in the centre of the
steering wheel; the front passenger(s) airbag is
fitted in the dashboard above the glove box.
Malfunction
If this warning lamp comes on,
contact a CITROËN dealer to have
the system checked.
Lateral airbags and curtain
airbags
If your vehicle is fitted with lateral airbags,
these are fitted to the front seat backrests on
the door side.
Curtain airbags are fitted to the door pillars and
the upper part of the passenger compartment,
in the roof over the front cab seats.
They inflate between the occupant and the
glazed area.
They are deployed independently of each other
depending on which side the collision occurs.
