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.

check that warning lamp P
on the instrument panel is
permanently lit.
Never leave a child alone inside the
vehicle with the ignition on, as they
could release the parking brake.

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), position P
(automatic gearbox) or M or R
(6-speed electronic gearbox).

 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 igni-
tion is switched off then on again.
If the reinitialisation of the park-

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.

HILL START ASSIST
System which holds your vehicle tem-
porarily (approximately 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 stationary, 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
