Airbags
General information
System designed to contribute towards
improving the safety of the occupants (with
the exception of the rear centre passenger)
in the event of violent collisions. The airbags
supplement the action of the seat belts fitted
with force limiters (all except the centre rear
passenger belt).
If a collision occurs, the electronic detectors
record and analyse the front and side impacts
sustained in the impact detection zones:
-
i
n the case of a serious impact, the airbags
are deployed instantly and contribute
towards better protection of the occupants
of the vehicle (with the exception of the
rear centre passenger); immediately after
the impact, the airbags deflate rapidly so
that they do not hinder visibility or the exit
of the occupants,
-

i
n the case of a minor or rear impact or in
certain roll-over conditions, the airbags
may not be deployed; the seat belt
alone contributes towards ensuring your
protection in these situations. The airbags do not operate when the
ignition is switched off.
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.
Impact detection zones
A. Front impact zone.
B. S
ide impact zone.
Deployment of one or more of the
airbags is accompanied by a slight
emission of 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 slight
irritation.
The noise of detonation related to the
deployment of one or more airbags
may result in a slight loss of hearing for
a short time.

deactivation
Only the passenger's front airbag can be
deactivated:
F
i
nsert the key in the passenger airbag
deactivation switch,
F

t
urn it to the "OFF" position,
F

t
hen, remove the key keeping the switch in
the new position.
According to version, this warning
lamp comes on in the instrument
panel and/or in the seat belt and
passenger's front airbag warning
lamps display when the ignition is on
and until the airbag is reactivated. To assure the safety of your child,
the passenger's front airbag must be
deactivated when you install a rear ward
facing child seat on the front passenger
seat.
Other wise, the child would risk being
seriously injured or killed if the airbag
were deployed.
Reactivation
When you remove the child seat, turn the
switch to the "ON"
position to reactivate the
airbag and so assure the safety of your front
passenger in the event of an impact.
With the ignition on, this warning
lamp comes on in the seat belt and
passenger's front airbag warning
lamps display for approximately
one minute, if the passenger's front
airbag is activated.
Operating fault
If this warning lamp comes on in
the instrument panel, contact a
CITROËN dealer or a qualified
workshop to have the system
checked. The airbags may no longer
be deployed in the event of a serious
impact.
Safety

185
Avoid attaching heavy objects to the
key or the remote control, which would
weigh down on its blade in the ignition
switch and could cause a malfunction.
It could adversely affect the
deployment of the front airbag.
Starting-switching off the engine with the key
It has 3 positions:
- p osition 1 (Stop) : insert and removing
the
key,
-

p
osition 2 (Ignition on) : steering column
unlocked, ignition on, Diesel preheating,
engine running,
-

p
osition 3 (Starting) .
Ignition switch
Ignition on position
It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Once the state of charge of the battery drops
to the reserve level, the system switches to
energy economy mode: the power supply is
cut off automatically to preserve the remaining
battery charge.
Switching off the engine leads to a loss
of braking assistance.
driving

In wintry conditions, the warning lamp
can stay on for a longer period. When
the engine is hot, the warning lamp
does not come on.
In certain cases, you may have to apply
more force to the steering (wheels on
full lock, for example). If the engine does not start straight
away, switch off the ignition. Wait a
few moments before operating the
starter motor again. If the engine does
not start after several attempts, do not
keep trying: you risk damaging the
starter motor or the engine. Contact
a CITROËN dealer or a qualified
workshop.In temperate conditions, do not leave
the engine at idle to warm up but move
off straight away and drive at moderate
speed.
Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion
engines emit toxic exhaust gases,
such as carbon monoxide. Danger of
intoxication and death.
In very severe wintry conditions
(temperatures below -23°C), to ensure
the correct operation and durability of
the mechanical components of your
vehicle, engine and gearbox, it is
necessary to leave the engine running
for 4 minutes before moving off.

Anti-theft protection
Electronic engine immobiliser
In the event of a fault, you are
informed by illumination of this
warning lamp, an audible signal
and/or the display of a message,
depending on version.
Keep safely, away from your vehicle,
the label attached to the keys given to
you on acquisition of the vehicle.
In this case, your vehicle will not start; contact
a CITROËN dealer as soon as possible. The keys contain an electronic chip which has
a special code. When the ignition is switched
on, this code must be recognised for engine
starting to be authorised.
This electronic engine immobiliser locks the
engine management system a few minutes
after the ignition is switched off and prevents
starting of the engine by anyone who does not
have the key.

isplay of the message "Parking
brake on".
When the driver’s door is opened with the
engine running, a message is displayed
accompanied by an audible signal if the parking
brake has not been applied, except in the case
of an automatic gearbox with the gear lever in
position P . The full application of the parking brake is

application of the parking brake. This is
obtained by means of a long pull on the control
lever A , until you see the message "Parking
brake on maximum" and a beep is heard.
Maximum application is essential:

or a trailer, if the automatic functions are
activated but you are applying the parking
brake manually,
-

w
hen the gradient you are parked on may
vary (e.g. on a ferry, on a lorry, during
towing).
In the case of towing, a loaded vehicle
or parking on a gradient, make a
maximum application of the parking
brake then turn the front wheels
towards the pavement and engage a
gear when you park.
After a maximum application, the
release time will be longer.
