For the airbags to be fully
effective, observe the following
safety rules: 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.
If possible, do not smoke as deploy-
ment 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.
Lateral airbags
Use only approved covers on the
seats. These will not hinder infl a-
tion of the lateral airbags. Consult a
CITROËN dealer.
Do not fi x or attach anything to the
seat backs (clothing...). This could
cause injury to the chest or arms if
the lateral airbag is triggered.
Do not sit with the upper part of the
body any nearer to the door than
necessary. Curtain airbags
Do not fi x or attach anything to
the roof. This could cause injury
to the head if the curtain airbag is
triggered.
Do not remove the grab handles in-
stalled on the roof, they play a part
in securing the curtain airbags.
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...). This could hamper the
operation of the airbags or injure the
occupants.
After an accident or if the vehicle has
been stolen or broken into, have the
airbag systems checked.
All work on the airbag system is strict-
ly forbidden unless it is carried out by
qualifi ed personnel of the CITROËN
dealer network.
Even if all of the precautions men-
tioned are observed, a risk of injury
or of minor burns to the head, chest
or arms when an airbag is triggered
cannot be ruled out. The bag infl ates
almost instantly (within a few millisec-
onds) then defl ates within the same
time discharging the hot gas via open-
ings provided for this purpose.

ELECTRIC PARKING BRAKE
The electric parking brake operates
as follows:
- Automatic application/release
Application is automatic when the engine stops, release is automatic
on use of the accelerator.
- Manual application/release

Manual application/release of the parking brake is possible
by pulling control lever A while
pressing the brake pedal. Manual application
With the vehicle stationary, to apply
the parking brake whether the engine
is running or not,
pull control lever A . Manual release
With the ignition on or the engine
running, to release the parking
brake, press on the brake pedal, or
the accelerator,
pull then release
control lever A .
- the extinction of the warning lamp P in con-
trol lever A and in the
instrument panel,
- the display of a message "Hand- brake off" in the multifunction
screen.
The application of the parking brake
is confi rmed by:
-
the lighting of the warning
lamp P in control lever A
and in the instrument panel,
- the display of a message "Hand- brake on" in the multifunction
screen.
When the driver’s door is
opened with the engine running,
a beep is heard and a message
displayed if the parking brake has not
been applied.
Before getting out of the vehicle, check
that the warning lamp P is on fi xed in
the instrument panel (not fl ashing). The full application of the parking
brake is confi rmed by:

P in control lever A and in
the instrument panel, Automatic release
The electric parking brake
releases
automatically and progressively
when you press the accelerator:

and in the instrument panel,
- the display of a message "Hand- brake off" in the multifunction
screen.
When stationary, with the engine
running, do not press the acceler-
ator pedal unnecessarily, as you
may release the parking brake.
Maximum application
If necessary, you can use maximum
application of the parking brake. It
is obtained by means of a long pull
on control lever A , until you see the
message "Handbrake on" and an
audible signal is heard.

Maximum application is essential:
- when towing a caravan or a trail- er, if the automatic functions are
activated but you are applying
the parking brake manually,
- when the gradient you are parked on is variable in its effect (e.g. on
a ferry, in a lorry, during towing),
- when towing, when loaded or when parking on a gradient, turn
the front wheels towards the
pavement and engage a gear
when you park,
- after a maximum application, the release time will be longer.
Before leaving the vehicle,
check that warning lamp P
in the instrument panel is
on fi xed, not fl ashing.
Never leave a child alone inside the
vehicle with the ignition on, as they
could release the parking brake.
- the display of a message "Hand-
brake on" in the multifunction

Dynamic emergency braking
In the event of a failure of the ve-
hicle’s main braking system or in
an exceptional situation (e.g. driver
taken ill, under instruction, etc) a con-
tinuous pull on the control lever A will
stop the vehicle.
The electronic stability programme
(ESP) provides stability during dy-
namic emergency braking.
If the dynamic emergency braking
malfunctions, one of the following
messages will be displayed in the
multifunction screen:
- "Parking brake faulty".
- "Parking brake control faulty". If a failure of the ESP sys-
tem is signalled by the light-
ing of this warning lamp,
then braking stability is not
guaranteed. In this event, stability
must be assured by the driver by
repeating alternate "pull-release"
actions on control lever A .
The dynamic emergency
braking must only be used in
exceptional circumstances.

D R I V I N G
Emergency release In the event of a malfunction of the
electric parking brake or the battery
running fl at, an emergency mecha-
nism can release the parking brake.

 Immobilise the vehicle, with the
engine running, by engaging fi rst
gear (manual gearbox), posi-
tion P (automatic gearbox) or M
or R (6-speed electronic gearbox
system).

 Switch off the engine, but leave
the ignition on.
If the vehicle cannot be immo- bilised, do not do anything and
contact a CITROËN dealer with-
out delay.

 Fetch the vehicle blocks E and
the release tool F (handle) from
the toolbox.

 If on a gradient: chock the vehi-
cle by placing the blocks in front
of or behind the front wheels, on
the falling side of the gradient.
If on level ground: chock the vehicle by placing the blocks in
front of and behind one of the
front wheels.
 Slide the front left-hand seat
back as far as possible.

 Lift up the fl oor plug

on the
carpet in front of the seat.

 Pierce the tab C on the tube D
with the release tool F .

 Place the end of the handle F in
the tube D .

 Turn the release tool F clock-
wise.
For safety reasons , it is

essential to continue turning the
device as far as it will go. The
parking brake is released.

 Remove the release tool F and
store it with the blocks E in the
toolbox.
- The operation of the parking brake reinitialises itself when the
ignition is switched off then on
again. If the reinitialisation of the
parking brake proves impossible,
contact a CITROËN dealer.
- The subsequent time required for application may be longer
than during normal operation.
When the release tool F is engaged, do not operate the control lever or the igni tion switch.
Immobilisation of the vehicle is no longer assured once the ma nual emergency release has been used.
The emergency release system cannot be used to apply the parking brake mechanically.
Take care not to allow moisture or dust in the proximity of th e plug.
For safety reasons, contact a CITROËN dealer as soon as possible to have the plug replaced.
