Electric parking brake


The electric parking brake combines
2 operational modes:


- Automatic Application/Release

Application is automatic when the engine
stops, release is automatic on use of the
accelerator (activated by default),

- Manual Application/Release

The parking brake can be applied/released
manually by pulling control lever A
.
Do not place any object (packet of
cigarettes, telephone...) between the
gear lever and the electric parking
brake control lever.
It is recommended that you do not
apply the parking brake in very cold
conditions (ice) and during towing
(breakdown, caravan...). Deactivate the
automatic functions and release the
parking brake manually.

If this warning lamp comes on in
the instrument panel, the automatic
mode is deactivated.

Programming the mode

Depending on the country of sale of the vehicle,
the automatic application when the engine is
switched off and the automatic release when
you press the accelerator can be deactivated.
Activation/deactivation is done
using the vehicle configuration
menu; refer to the section covering
the configuration of your vehicle's
systems.
The parking brake is then applied and released
manually. When the driver's door is opened,
there is an audible signal and a message is
displayed if the brake is not applied.

193Driving
With the ignition on or the engine running, to
release the parking brake, press
on the brake

pedal
or the accelerator, pull then release

control A
.


Manual release


Before leaving the vehicle, ensure
that parking brake warning lamp in
the instrument panel is on fixed, not
flashing.



Manual application

With the vehicle stationary, to apply the parking
brake whether the engine is running or off, pull

control lever A
.
The application of the parking brake is
confirmed by:


- illumination of the braking warning
lamp and of the P
warning lamp in
the control lever A
,

- display of the message
"Handbrake on".
When the driver’s door is opened with the
engine running, a message is displayed
accompanied by an audible signal if the parking
brake has not been applied, except in the case
of an automatic gearbox with the gear lever in
position P
. The full application of the parking brake is
confirmed by:


- the braking warning lamp and
the P
warning lamp in the control
lever A
going off,

- display of the message
"Handbrake off".

If you pull control lever A
without pressing
the brake pedal, the parking brake will
not be released and a warning lamp will
come on in the instrument panel.


Maximum application

If necessary, you can make a maximum
application
of the parking brake. This is
obtained by means of a long pull
on the control
lever A
, until you see the message "Handbrake
on maximum" and a beep is heard.

Maximum application is essential:



- in the case of a vehicle towing a caravan
or a trailer, if the automatic functions are
activated but you are applying the parking
brake manually,

- when the gradient you are parked on may
vary (e.g. on a ferry, on a lorry, during
towing),

In the case of towing, a loaded vehicle
or parking on a gradient, make a
maximum application of the parking
brake then turn the front wheels
towards the pavement and engage a
gear when you park.
After a maximum application, the
release time will be longer.

With the vehicle stationary, the parking brake
is automatically applied when the engine is
switched off.



Automatic application,
engine off

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.

Before leaving the vehicle, ensure
that parking brake warning lamp in
the instrument panel is on fixed (not
flashing).
Never leave a child alone inside the
vehicle with the ignition on, as they
could release the parking brake.


- illumination of the braking warning
lamp and of the P

stationary, in order to immobilise the vehicle
it is essential to manually
apply the parking
brake by pulling
control lever A
.


Immobilising the vehicle,
engine running

The emergency braking must only be
used in exceptional circumstances.

Before leaving the vehicle, ensure
that parking brake warning lamp in
the instrument panel is on fixed, not
flashing.
The application of the parking brake is
confirmed by:


- illumination of the braking
warning lamp and the P
warning
lamp in the control lever A
,

- display of the message
"Handbrake on".
When the driver’s door is opened, a message is
displayed accompanied by an audible signal, if
the parking brake has not been applied, except

.


Particular situations


In cer tain situations (e.g. star ting the engine),
the parking brake can automatically alter its
force. This is normal operation.
To advance your vehicle a few centimetres
without star ting the engine, but with the ignition
on, press on the brake pedal and release the
parking brake by pulling
then releasing
the
control lever A
. The full release of the parking
brake is confirmed by the warning lamps
in the control lever A
and in the instrument
panel going off and display of the message
"Handbrake off".
If the parking brake develops a fault while
applied
or if the battery runs flat, an
emergency release is always possible.



Emergency braking



In the event of failure of the electronic
stability control system, signalled
by the illumination of this warning
lamp, braking stability is then not
guaranteed.
In this event, stability must be assured by the
driver by repeating alternate "pull-release"
actions on the control lever A
. In the event of a failure of the main ser vice
brake or in an exceptional situation (e.g. driver
taken ill, under instruction, etc) a continuous
pull on the control lever A
will stop the vehicle.
The electronic stability control provides stability
during emergency braking.
If the emergency braking malfunctions,
the message "Parking brake faulty" will be
displayed.

In the event of the electric parking brake
malfunctioning or the battery running flat, an
emergency manual device can release the
parking brake.


)
Immobilise the vehicle (or keep it
stationary, if the brake pedal is pressed),
with the engine running, by engaging
first gear (manual gearbox), position P

(automatic gearbox) or position M
or R

(6 -speed electronic gearbox system).









Emergency release


)
Switch off the engine but leave the ignition
on. If it is not possible to immobilise the
vehicle, do not operate the control and
contact a CITROËN dealer or a qualified
workshop without delay.

with the blocks in the toolbox under the
boot carpet.
For safety reasons, after this operation
it is essential to contact a CITROËN
dealer or a qualified workshop without
delay to replace the protective cover.
Following an emergency unlocking,
immobilisation of the vehicle is no
longer assured once the manual
emergency release has been deployed
and the manual control does not allow
the re-application of your parking
brake.
Take no action, either on the control
lever A
, or stopping star ting the engine
while the release device is engaged.
Take care not to allow moisture or dust
in the proximity of the protective cover.


- The operation of the parking brake
reinitialises when the ignition is switched
off then on again. If the reinitialisation
of the parking brake proves impossible,
contact a CITROËN dealer or a qualified
workshop.

- The subsequent time required for
application may be longer than during
normal operation.
