 with an electronic gearbox , ac-
celerate with the selector in posi-
tion A , M or R .
Full release of the parking brake is
confi rmed by: - the extinction of warning lamp P on control A and
on the instrument panel,
- the display of a message "park- ing brake released" on the multi-
function screen. Activation/Deactivation of the
automatic functions
The automatic application when the en-
gine is switched off and the automatic
release when you press the accelerator
can be deactivated. Activation/deactiva-
tion is performed using the confi guration
menu of the multifunction screen. To do
so, select "Personalisation/Confi guration/
Defi ne the Vehicle parameters/Driving
assistance/Automatic handbrake".
The deactivation of these
functions is confi rmed by the
lighting of this warning lamp
on the instrument panel.
With the automatic functions deacti-
vated, the application and release of
the parking brake are done manually.
The deactivation of the auto-
matic functions is recommend-
ed in particularly cold condi-
tions (ice) and during towing
(breakdown, caravan...)
Manual operation
Manual application/release of the
parking brake is always possible.
Application
With the vehicle stationary, to apply
the parking brake whether the engine
is running or off, pull on control A .
The application of the parking brake
is confi rmed by: - the lighting of the warning lamp on control A and of
warning lamp P on the in-
strument panel,
- the display of a message "park- ing brake applied" on the multi-
function 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.

Release
With the ignition on or the engine run-
ning, to release the parking brake,
press on the brake pedal, pull then
release control A .
The full application of the parking
brake is confi rmed by: - the extinction of the warn-ing lamp on control A and
of warning lamp P on the
instrument panel,
- the display of a message "park- ing brake released" on the multi-
function screen.
If you pull control A without pressing
the brake pedal, the parking brake
will not be released and the "Foot on
brake" warning lamp will light up on
the instrument panel.
When stationary, with the
engine running, do not
press the accelerator pedal
unnecessarily, as you may release
the parking brake. Maximum application
If necessary, you can utilise
maxi-
mum application of the parking
brake. It is obtained by means of
a long pull on control A , until you
see the message "parking brake ap-
plied" and a beep is heard.

Maximum application is essential:
- in the case of a vehicle towing a caravan or a trailer, if the au-
tomatic 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),
- in the case of towing, a loaded vehicle or 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. Particular situations
In certain situations (e.g. starting
the engine), the parking brake can
automatically alter its force. This is
normal operation.
To advance your vehicle a few cen-
timetres without starting the engine,
but with the ignition on, press on the
brake pedal and release the park-
ing brake
by pulling then releasing
control A .
The full release of the parking brake
is confi rmed by the extinction of
warning lamp P (red) on the instru-
ment panel and the display of a
message "parking brake released"
on the multifunction screen.
If the parking brake malfunctions

while applied or if the battery runs
fl at, an emergency release is always
possible.

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
continuous pull on control 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 on 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" ac-
tions on control A .
The dynamic emergency
braking must only be used in
exceptional circumstances.

D R I V I N G
Emergency unlocking In the event of the electronic parking
brake malfunctioning or the battery
running fl at, an emergency manual
device can unlock the parking brake.

 Immobilise the vehicle, with the
engine running, by engaging fi rst
gear (manual gearbox), position

P (automatic gearbox) or M or

R (6-speed electronic gearbox),
then switch off the engine.
If it is impossible to immobilise the vehicle, do not action the
control and urgently contact a
CITROËN dealer.

 Fetch the vehicle blocks and the
unlocking device (braided cable)
from the toolbox.

 Immobilise the vehicle by plac-
ing blocks at the front and at the
rear of one of the rear wheels.

 Slide the front left-hand seat
back as far as possible.

 Lift up the fl oor plug B in the car-
pet under the seat.
 Pierce the tab C on the tube D
with the unlocking device.

 Place the unlocking device in the
tube D .

 Turn the unlocking device clock-
wise. For safety reasons
, it is

essential to continue turning the
device as far as it will go or until
you hear a knocking noise. The
parking brake is released.

 Remove the unlocking device
and store it with the blocks in the
toolbox.
- The operation of the parking brake reinitialises when the ig-
nition is switched off then on
again. If the reinitialisation of the
parking brake proves impossi-
ble, contact a CITROËN dealer.
- The subsequent time required for application may be longer
than during normal operation.
For safety reasons, after this manoeuvre it is essential to cont act a CITROËN dealer urgently to have the plug
replaced.
Following an emergency unlocking, immobilisation of the vehi cle is no longer guaranteed once the manual emer-
gency unlocking has been deployed and the manual control doe s not allow the re-application of your parking
brake.
Take no action, either on control A , or stopping starting the engine while the unlocking de vice is engaged.
Take care not to allow moisture or dust in the proximity of th e plug.
