Advice
Front airbags
Do not drive holding the steering wheel by its
spokes or resting your hands on the centre
part of the wheel.
Passengers must not place their feet on the
dashboard.
Do not smoke as deployment of the airbags
can cause burns or the risk of injury from a
cigarette or pipe.
Never remove or pierce the steering wheel or
hit it violently.
Do not fit or attach anything to the steering
wheel or dashboard, this could cause injuries
with deployment of the airbags.
Lateral airbags
Use only approved covers on the seats,
compatible with the deployment the lateral
airbags. For information on the range of
seat covers suitable for your vehicle, you
can contact a CITROËN dealer.
Do not fix or attach anything to the seat
backs (clothing...). This could cause injury
to the chest or arms if the lateral airbag is
deployed.
Do not sit with the upper part of the body
any nearer to the door than necessary.
Sit in a normal upright position.
Wear a correctly adjusted seat belt.
Do not leave anything between the occupants
and the airbags (a child, pet, object...), nor
fix or attach anything close to the inflation
trajectory of the airbags; this could cause
injuries during their deployment.
Never modify the original definition of your
vehicle, particularly in the area directly
around the airbags.
After an accident or if the vehicle has been
stolen or broken into, have the airbag
systems checked.
All work on the airbag system must be
carried out by a CITROËN dealer or a
qualified workshop.
Even if all of the precautions mentioned
are observed, a risk of injury or of minor
burns to the head, chest or arms when an
airbag is deployed cannot be ruled out. The
bag inflates almost instantly (within a few
milliseconds) then deflates within the same
time discharging the hot gas via openings
provided for this purpose.
Curtain airbags
Do not fix or attach anything to the roof.
This could cause injury to the head if the
curtain airbag is deployed.
If fitted on your vehicle, do not remove the
grab handles installed on the roof, they play
a part in securing the curtain airbags.
For the airbags to be fully effective, observe the safety recommendations below:
The vehicle's front door panels include side
impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior
trim could compromise the operation of
these sensors - Risk of malfunction of the
lateral airbags!
Such work must only be done by a
CITROËN dealer or a qualified workshop.

When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without exceeding
it.
Air density decreases with altitude, thus
reducing engine per formance. Above
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
Side wind
F Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine
as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam
height of your vehicle.
For more information on Adjusting the
headlamp beam height , refer to the
corresponding section.
For more information on Weights
, refer
to the corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
If the exterior temperature is high, it
is recommended that the engine be
allowed to idle for 1 to 2 minutes after
the vehicle comes to a stop, to facilitate
its cooling.

Tyre under-inflation detection
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.Driving with under-inflated tyres
increases fuel consumption.The tyre pressures for your vehicle can
be found on the tyre pressure label.
The tyre pressures must be checked
when the tyres are cold (vehicle
stopped for 1 hour or after driving for
less then 6 miles (10 km) at moderate
speed). Other wise, add 0.3 bar to the
values indicated on the label.
For more information on Identification
markings
, including the tyre pressure
label, refer to the corresponding
section.
This system does not avoid the need
to check the tyre pressures regularly
(including the spare wheel) and before
a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).
The tyre under-inflation detection system is an
aid to driving which does not replace the need
for vigilance on the part of the driver. Pressure sensors are located in the valve of
each tyre (except the spare wheel).
The system triggers an alert if a drop in
pressure is detected in one or more tyres.

Under-inflation alert
The loss of pressure detected does not
always lead to visible deformation of
the tyre.
Do not rely on just a visual check.This alert is also displayed when one or
more wheels is not fitted with a sensor
(e.g. a space-saver or steel spare
wheel).
The alert is maintained until the tyre or
tyres concerned is reinflated, repaired
or replaced.
The spare wheel (space-saver type or
a steel rim) does not have a sensor.
The alert is given by the fixed
illumination of this warning lamp,
accompanied by an audible signal,
and depending on equipment, the
display of a message.
In the event of a problem on one of the tyres,
the symbol or the message appears, depending
on equipment, to identify it.

warning lamp accompanied by the
illumination of the service warning
lamp indicates a fault with the system.
Go to a CITROËN dealer or a qualified
workshop
to have the system checked or,
following the repair of a puncture, to have the
original wheel, equipped with a sensor, refitted.

n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment).
Any tyre repair or replacement on a wheel
fitted with this system must be carried out by a
CITROËN dealer or a qualified workshop.
If after changing a tyre, a wheel is not detected
by your vehicle (e.g. fitting snow tyres),
you must have the system reinitialised by a
CITROËN dealer or a qualified workshop. In this case, monitoring of the tyre pressures is
not assured.
