SAFETY
Air bags
SIDE AIR BAGS
Activation
It is triggered unilaterally in the event of a
serious side impact, perpendicular to the
longitudinal centreline of the vehicle on
a horizontal plane and directed from the
outside towards the inside of the vehicle.
The side air bag inflates between the
front occupant of the vehicle and the
corresponding door trim pad. In the event of a minor impact or bump
on the side of the vehicle or if the
vehicle rolls over, the air bag may not be
triggered.
Operating fault
If this warning light comes on on
the instrument panel, consult a
CITROËN dealer without delay to
have the system checked. The air
bags may no longer be triggered
in the event of a serious impact.

SAFETY
Air bags
For the air bags to be fully effective, observe the following safety rules:
Sit in a normal upright position.
Wear a correctly adjusted seat belt.
Do not leave anything between the
occupants and the air bags (a child,
pet, object, etc.). This could hamper the
operation of the air bags or injure the
occupants.
After an accident or if the vehicle has been
stolen or broken into, have the air bag
systems checked.
All work on the air bag systems is strictly
forbidden unless it is carried out by the
qualified personnel of a CITROËN dealer .
Even if all of the precautions mentioned are
observed, a risk of injury or of slight burns
to the head, chest or arms when an air bag
is triggered cannot be ruled out. In fact,
the bag inflates almost instantly (within a
few milliseconds) then deflates within the
same time, discharging the hot gas through
openings provided for this purpose.
Front air bags
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
fascia.
Smoke as little as possible as deployment of
the air bags can cause burns or the risk of
injury from a cigarette or pipe.
Never remove or pierce the steering wheel
or hit it violently.
Side air bags
Only put approved covers on the seats.
These will not hinder the triggering of the
side air bags. Consult a CITROËN dealer .
Do not fix or glue anything to the seat backs.
This could cause injury to the chest or arms
when the side air bag inflates.
Do not sit with the upper part of the body
any nearer to the door than necessary.

Air bags
AIR BAGS
The air bags have been designed to
maximise 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, the
electronic detectors record and analyse the
front and side impacts suffered in the impact
detection zones:
- in the event of a serious impact, the air bags inflate instantly and protect the
occupants of the vehicle. Immediately
after the impact, the air bags deflate
rapidly, so that they do not hinder the
visibility of the occupants nor their
possible exit from the vehicle. - in the event of a minor or rear impact
and in certain roll-over conditions, the air
bags will not be deployed; the seat belt
alone is sufficient to provide maximum
protection in these situations.
The seriousness of the collision depends on
the nature of the obstacle and the speed of
the vehicle at the moment of impact. Air bags only operate when the
ignition is switched on.
This equipment only operates once. If a
second impact occurs (during the same or
a subsequent accident), the air bag will not
operate.
The triggering of an air bag or air bags
is accompanied by a slight discharge of
harmless smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system.
This smoke is not harmful, but sensitive
individuals may experience some irritation.
The noise of the detonation may result in a
slight loss of hearing for a short time.
It is imperative that the passenger
air bag is disarmed if a child seat is
installed facing rearwards. Refer to the
"Child safety" section of chapter 5.

92
Air bags
FRONT AIR BAGS
The front air bags are incorporated in the
centre of the steering wheel for the driver
and in the fascia for the front passenger.
Activation
They are deployed simultaneously, unless
the passenger's front air bag has been
disarmed, in the event of a serious front
impact.
The front air bag inflates between the front
occupant of the vehicle and the fascia to
cushion his forward movement.
Disarming
The passenger's front air bag alone can be
disarmed. The air bag is disarmed from the
trip computer. The air bag warning light on the
instrument panel is lit throughout
the period of disarming. To ensure the safety of your child, it
is essential to disarm the passenger
air bag when you install a rear-facing child
seat on the front passenger seat. Otherwise,
the child would risk being killed or seriously
injured if the air bag were to inflate.
Refer to the "MENU" section of
chapter 3, then select OFF on the
"Passenger air bag" menu.
Operating fault
If the two air bag warning lights are lit
continuously, do not install a rear-facing
child seat. Consult a CITROËN dealer . If this warning light comes
on on the instrument panel,
accompanied by an audible signal
and a message on the display,
consult a CITROËN dealer without delay
to have the system checked. The air bags
may no longer be triggered in the event of a
serious impact.

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, ...).

106
Battery
The batteries contain harmful
substances such as sulphuric acid and
lead. They must be discarded in accordance
with the provisions of the law and must not,
in any circumstances, be discarded with
household waste.
Take used batteries to a special collection
point.
Before disconnecting the battery, you must
wait for 2 minutes after switching off the
ignition.
Never disconnect a terminal when the
engine is running.
Never charge a battery without first
disconnecting the terminals.
Close the windows and doors before
disconnecting the battery.
After every reconnection of the battery,
switch on the ignition and wait 1 minute
before starting to allow the electronic
systems to be initialised. If slight difficulties
are experienced after this, please consult a
CITROËN dealer . It is advisable to disconnect the battery
if the vehicle is not to be used for a
period of more than one month.
If the battery has been disconnected
for some time, it may be necessary to
reinitialise the following functions:
- the display parameters (date, time, language, distance unit and temperature
unit),
- the radio stations,
- the central locking.
Some settings are cleared and must be
reprogrammed, consult a CITROËN dealer .
