To immobilise the vehicle,
engine running
With the engine running and the ve-
hicle stationary, in order to immobi-
lise the vehicle you need to manually
apply the parking brake by pulling
on control A .
The application of the parking brake
is confi rmed by: - the lighting of warning lamp P on control A and
on the instrument panel,
- the display of a message "park- ing brake applied" on the multi-
function screen.
When the driver’s door is opened, a
beep is heard and a message dis-
played if the parking brake has not
been applied.
Before leaving the vehicle,
check that warning lamp P
on the instrument panel is
permanently lit. 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 (towing,
etc.) 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.

Activation/Deactivation of the
automatic functions *
The automatic application when the
engine is switched off and the au-
tomatic release when you press
the accelerator can be deactivated.
Activation/deactivation is performed
using the confi guration menu of the
multifunction screen. To do so, select
"Personalisation/Confi guration/Defi ne
the Vehicle parameters/Driving assis-
tance/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
deactivated, the application and
release of the parking brake are
done manually.

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 control faulty". If a failure of the ESP sys-
tem is signalled by the ligh-
ting 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.

Emergency unlocking In the event of the electric parking
brake malfunctioning or the battery
running fl at, an emergency mecha-
nism can unlock 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 gear-
box).

 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 unlocking tool F (handle)
from the toolbox.

 Immobilise the vehicle by placing
blocks E 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
on the
carpet in front of the seat.

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

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

 Turn the unlocking tool F 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 tool F and
store it with the blocks E 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 to ol F is engaged.
Take care not to allow moisture or dust in the proximity of th e plug.

HILL START ASSIST
System which keeps your vehicle
immobilised temporarily (approxi-
mately 2 seconds) when starting on
a gradient, the time it takes to move
your foot from the brake pedal to the
accelerator pedal.
This function is only active when:
- the vehicle is completely station-ary, with your foot on the brake
pedal,
- in particular conditions on a slope,
- with the driver’s door closed.
The hill start assist function cannot
be deactivated. Operation
Operating fault
If a malfunction of the system oc-
curs, these warning lamps come on.
Contact a CITROËN dealer to have
the system checked.

On an ascending slope, with the
vehicle stationary, the vehicle is
held for a brief moment when you
release the brake pedal:
- provided you are in fi rst gear or neutral on a manual gearbox,
- provided you are in A or M on an
electronic gearbox,
- provided you are in D or M on an
automatic gearbox.
On a descending slope, with the
vehicle stationary and reverse
gear engaged, the vehicle is held
for a brief moment when you re-
lease the brake pedal.
Do not exit the vehicle while
it is being held in the hill
start assist phase.
If you need to exit the ve-
hicle with the engine running,
manually apply the parking brake
