ELECTRIC PARKING BRAKE
The electric parking brake combines
2 operational modes:
- AUTOMATIC
Automatic application when the engine stops and automatic re-
lease on use of the accelerator
(automatic operation by default),
- MANUAL
Manual application/release of the parking brake is always pos-
sible by pulling control A while
pressing the brake pedal. Automatic operation
Application with the engine off
With the vehicle stationary, the park-
ing brake
is automatically applied
when the engine is switched off.
The application of the parking brake
i s c o n fi r m e d b y :
Application with the engine running
With the engine running and the ve-
hicle stationary, in order to immobil-
ise the vehicle you need to manually
apply the parking brake by pulling
on control A .
The application of the parking brake
i s c o n fi r m e d b y :
- the lighting of the warning
lamp on control A and on
the instrument panel,
Before leaving the vehicle,
check that warning lamp P on
the instrument panel is per-
manently lit.
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" on the instrument pan-
el screen.
T h e n o i s e o f o p e r a t i o n w i l l c o n fi r m
to you the application/release of
your electric parking brake. - the lighting of warning
lamp P on control A and
on the instrument panel,
- the display of a message "hand- brake on" on the instrument pan-
el 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,

Release
The electric parking brake releases
automatically and progressively
when you press the accelerator:
with a manual gearbox ( fi r s t
gear or reverse gear engaged),
press down fully on the clutch
pedal then press on the acce-le-
rator pedal and move off.
with an automatic gearbox , ac-
celerate with the selector in posi-
tion D , M or R .
Full release of the parking brake is
c o n fi r m e d b y : - the warning lamp P on
control A and on the in-
strument panel going out,
- the display of a message "hand- brake off" on the instrument pan-
el screen.
When stationary, with the engine
running, do not press the accelera-
tor pedal unnecessarily (particularly
when starting the engine, including
in neutral), as you may release the
parking brake. Activation/Deactivation of
the automatic functions *
Automatic application when switch-
ing off the engine and automatic
release when moving off can be de-
activated. The activation/deactiva-
tion is done in the instrument panel
s c r e e n c o n fi g u r a t i o n m e n u . S e l e c t
"Vehicle parameters/Comfort/Auto
handbrake".
Deactivation of these func-
tions is signalled by this
warning lamp in the instru-
ment panel.
With the automatic functions deac-
tivated, the parking brake must be
applied and released manually.
Deactivation of the automatic
functions is recommended
in very cold weather (freezing)
and when towing (recovery, cara-
van...). 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
i s c o n fi r m e d b y : - the lighting of the warning lamp on control A and of

Release
With the ignition on or the engine
running, to release the parking
brake, press on the brake pedal,
push then release control A .
The full application of the parking
b r a k e i s c o n fi r m e d b y :
- the warning lamp on con- trol A and the warning lamp
P on the instrument panel
going off,
- the display of a message "park- ing brake released" on the instru-
ment panel screen.
If you push control A without pressing
the brake pedal, the parking brake
will not be released and the message
"Apply foot on brake" will be dis-
played on the instrument panel.
When stationary, with the en-
gine running, do not press the
accelerator pedal unneces-
sarily, 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 "Max application of the
handbrake" 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 (starting the en-
gine...), the parking brake can auto-
matically alter its level of application.
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 parking
brake
by pushing then releasing
control A .
The full release of the parking brake
i s c o n fi r m e d b y t h e w a r n i n g l a m p P
(red) on the instrument panel going
off and the display of a message
"handbrake off" on the instrument
panel screen.
If the parking brake malfunctions
while applied o r i f t h e b a t t e r y i s fl a t ,
an emergency release is still pos-
sible.
To ensure correct operation of the
parking brake and therefore your
safety, the number of successive
application/release operations is
limited to eight.
If this number is exceeded, you are
warned by the message "Parking
brake faulty" and a warning lamp
fl a s h e s .

Dynamic emergency braking
In the event of a failure of the vehi-
cle’s main braking system or in an
exceptional situation (e.g. driver tak-
en ill, under instruction, etc) pull and
hold control A to stop the vehicle.
The electronic stability programme
( E S P ) p r o v i d e s s t a b i l i t y d u r i n g d y -
namic emergency braking.
If the dynamic emergency braking
malfunctions, one of the following
messages will be displayed on the
instrument panel display:
- "Parking brake faulty".
- "Parking brake control faulty". I f a f a i l u r e o f t h e E S P s y s -
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. Emergency parking brake
release
In the event of the electric parking
brake failing to release, an emer-
gency device can be used to release
the parking brake manually, provid-
ed that it is possible to immobilise
the vehicle while the procedure is
carried out.
If you can start the vehicle: with
the engine running, immobilise
the vehicle by applying the foot
brake while the operation is be-
ing carried out.
If you are unable to start the ve-
h i c l e ( fl a t b a t t e r y f o r e x a m p l e ) : d o
not use this device and contact
a CITROËN dealer. However, if
y o u a r e o b l i g e d t o p r o c e e d , fi r s t

HILL START ASSIST
S y s t e m w h i c h k e e p s y o u r v e h i c l e
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 certain conditions on a gradi- ent,
- with the driver’s door closed.
The hill start assist function cannot
be deactivated. Operation
On an ascending
gradient
, with
the vehicle stationary, the vehicle
is held for a brief moment when
you release the brake pedal:
- p r o v i d e d y o u a r e i n fi r s t g e a r o r neutral on a manual gearbox,
- provided you are in D or M on an
automatic gearbox.
On a descending
gradient
, 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 vehicle with
the engine running, manually apply
the parking brake and ensure that
the parking brake warning lamp
(on the instrument panel) and the
warning lamp P (on the control le-
ver A ) are permanently on.
