BRAKING ASSISTANCE
SYSTEMS
Group of supplementary systems which
help you to obtain optimum braking in
complete safety in emergency situa-
tions:


- anti-lock braking system (ABS),

- electronic brake force distribution
(EBFD),

- emergency braking assistance (EBA).

When braking in an emergency,
press very fi rmly without releas-
ing the pressure.
When replacing wheels (tyres
and rims), ensure that they con-
form to the manufacturer's rec-
ommendations.
When braking in an emergency,
press fi rmly without releasing
the pressure.



Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the sta-
bility and manoeuvrability of your vehi-
cle when braking, in particular on poor
or slippery surfaces.

Activation
The anti-lock braking system comes
into operation automatically when there
is a risk of wheel lock.
Normal operation of the ABS may make
itself felt by slight vibration of the brake
pedal.
Operating fault
If this warning lamp comes on,
accompanied by an audible
signal and a message in the
screen, it indicates a malfunc-
tion of the anti-lock braking system
which could result in loss of control of
the vehicle when braking.
If this warning lamp comes on,
together with the STOP
and
ABS
warning lamps, accompa-
nied by an audible signal and
a message in the screen, it indicates a
malfunction of the electronic brake force
distribution which could result in loss of
control of the vehicle when braking.

You must stop as soon as it is safe
to do so.











Emergency braking assistance

System which, in an emergency, en-
ables you to obtain the optimum braking
pressure more quickly, thus reducing
the stopping distance.

Activation
It is triggered by the speed at which the
brake pedal is pressed.
The effect of this is a reduction in the
resistance of the pedal and an increase
in braking effi ciency.
In either case, contact a CITROËN
dealer or a qualifi ed workshop.

TRAJECTORY CONTROL
SYSTEMS (ESP)

Anti-slip regulation (ASR) and
electronic stability control (ESC)

The anti-slip regulation (also known as
traction control) optimises traction to pre-
vent skidding of the wheels, by acting on
the brakes of the driving wheels and on
the engine.
The electronic stability control acts on
the brake of one or more wheels and
on the engine to keep the vehicle on the
trajectory required by the driver, within
the limits of the laws of physics.

Activation
These systems are activated automati-
cally each time the vehicle is started.
They come into operation in the event
of a grip or trajectory problem.
This is indicated by fl ashing of
this warning lamp in the instru-
ment panel.








Intelligent traction control
system ("Snow motion")
Your vehicle has a system to help driving
on snow: intelligent traction control.
This system detects situations of diffi -
cult surface adhesion that could make it
diffi cult to move off or make progress on
deep fresh snow or compacted snow.
In these situations, the intelligent trac-
tion control
limits the amount of wheel
slip to provide the best traction and tra-
jectory control for your vehicle.
In extremely severe conditions (deep
snow, mud, ...), when it proves impos-
sible to move off, it may be useful to
temporarily deactivate the ESP/ASR
systems to allow the wheels to spin
freely and so allow movement of the
vehicle.

Deactivation
In exceptional conditions (starting a
vehicle which is bogged down, stuck in
snow, on soft ground...), if you are un-
able to make progress, it may be ad-
visable to temporarily deactivate these
systems, so that the wheels can spin
freely and allow the vehicle to move.



Press the "ESP OFF"
button, locat-
ed near the steering wheel.
If the indicator lamp in the button comes
on, this indicates that these systems
are deactivated.
The use of snow tyres is strongly
recommended on surfaces of-
fering low levels of adhesion.

It is recommended that the systems be
reactivated as soon as possible.

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
.
If this warning lamp comes on
in the instrument panel, the au-
tomatic 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 auto-
matic release when you press the ac-
celerator can be deactivated.

It is recommended that you do
not apply the parking brake in
very cold conditions (ice) and
during towing (breakdown, cara-
van...). Deactivate the automatic
functions and release the park-
ing brake manually.



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
confi rmed by:



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


- display of the message
"Parking brake on".

Before leaving the vehicle, en-
sure that parking brake warning
lamp in the instrument panel is
on fi xed, not fl ashing.
When the driver’s door is opened with
the engine running, a message is dis-
played accompanied by an audible sig-
nal if the parking brake has not been
applied. Activation / deactivation is done
using the vehicle confi guration
menu; refer to the section cov-
ering the confi guration 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 sig-
nal and a message is displayed if the
brake is not applied.

Do not place any object (packet
of cigarettes, telephone...) be-
tween the gear lever and the
electric parking brake control
lever.

Manual release

With the ignition on or the engine run-
ning, to release the parking brake,
press
on the brake
pedal
or the accel-
erator, pull then release
control A
.
The full application of the parking brake
is confi rmed by:


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

- display of the message
"Parking brake off".
If you pull control lever A
with-
out 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 maxi-
mum application
of the parking brake.
This is obtained by means of a long
pull
on the control lever A
, until you see
the message "Parking brake on maxi-
mum" 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 manu-
ally,

- 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 maxi-
mum 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 re-
lease time will be longer.



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




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


- display of the message
"Parking brake on".

Before leaving the vehicle, en-
sure that parking brake warning
lamp in the instrument panel is
on fi xed (not fl ashing).
Never leave a child alone inside
the vehicle with the ignition on,
as they could release the park-
ing brake.

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.

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

- display of the message
"Parking brake off".

When stationary, with the engine
running, do not press the ac-
celerator pedal unnecessarily,
as you may release the parking
brake.



Immobilising the vehicle,
engine running
With the engine running and the vehi-
cle stationary, in order to immobilise the
vehicle it is essential to manually
ap-
ply the parking brake by pulling
control
lever A
.



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


- display of the message
"Parking brake on".

Before leaving the vehicle, en-
sure that parking brake warning
lamp in the instrument panel is
on fi xed, not fl ashing.



Particular situations


In certain situations (e.g. starting the
engine), the parking brake can auto-
matically alter its force. This is normal
operation.
To advance your vehicle a few centime-
tres without starting the engine, but with
the ignition on, press on the brake pedal
and release the parking brake by pull-
ing
then releasing
the control lever A
.
The full release of the parking brake is
confi rmed by the warning lamps in the
control lever A
and in the instrument
panel going off and display of the mes-
sage "Parking brake off".
If the parking brake develops a fault
while applied
or if the battery runs fl at,
an emergency release is always pos-
sible.

When the driver’s door is opened, a
message is displayed accompanied by
an audible signal, if the parking brake
has not been applied. The application of the parking brake is

Emergency braking

In the event of failure of the
electronic stability control sys-
tem, signalled by the illumi-
nation 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.
The emergency braking must
only be used in exceptional cir-
cumstances.











Emergency release

In the event of the electric parking brake
malfunctioning or the battery running
fl at, an emergency device can be used
to release the parking brake manually.
Access to tools
The tools are stowed in the storage box
under the boot carpet.
* Available according to equipment: if
these tools are not present, contact a
CITROËN dealer or a qualifi ed work-
shop to obtain them.
