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
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 instru-
ment panel display.
If you push control A without press-
ing the brake pedal, the parking
brake will not be released and the
message "Foot on brake necessary"
will be displayed 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 "Max application of the
parking brake" 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
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 parking
brake
by pushing 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 instrument panel display.
If the parking brake malfunctions

while applied or if the battery

runs fl at , an emergency release is
always possible.
To guarantee correct operation of
the parking brake and therefore
your safety, the number of succes-
sive 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 ashes.

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
(ESP) provides stability during dy-
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". 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 circum-
stances. Emergency unlocking
In the event of the electronic parking
brake malfunctioning or the battery
running fl at, an emergency man-
ual device can unlock the parking
brake.

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

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

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 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 vehicle with
the engine running, manually apply
the parking brake and ensure that
the parking brake warning lamp (on
the instrument panel) and the warn-
ing lamp P (on the control lever A )
are permanently on.

Automatic operation

 Move the selector to position D .
The gearbox constantly selects the
gear that is best suited to the follow-
ing parameters: - driving style,
- road profi le
- vehicle load.
The gearbox operates without requir-
ing any intervention on your part.
For certain manoeuvres (for exam-
ple overtaking), you can obtain max-
imum acceleration by pressing the
accelerator pedal hard down past
the mechanical force zone (point of
resistance), which then produces an
automatic change down to a lower
gear. When braking, the gearbox may
change down automatically in order
to provide effective engine braking.
If you lift your foot off the accelera-
tor abruptly, the gearbox will not en-
gage a higher gear.
Manual operation
Position of the selector for manual
gear changing.

 Move the selector to position M .

 Push the selector towards the
" + " sign to change up a gear.

 Pull the selector towards the " - "
sign to change down a gear. - If the vehicle stops or reduces
speed (for example when ap-
proaching a stop sign), the gearbox
changes down automatically to fi rst
gear.
- In sequential mode, it is not nec- essary to release the accelerator
during gear changes.
- A request to change gear is ac- cepted only if the engine speed
permits it.
- The SPORT and SNOW modes
do not operate in sequential
mode.

SPEED LIMITER
System which prevents the vehi-
cle from exceeding the speed pro-
grammed by the driver.
When the limit speed is reached, the
accelerator pedal no longer has any
effect.
The speed limiter is switched
on manually: a speed of at least
20 mph (approx. 30 km/h) must be
programmed.
The speed limiter can in no way
replace respect for speed limits or
vigilance and responsibility on the
part of the driver.
