system is an aid to driving which
does not replace the need for the
driver to be vigilant or to drive
responsibly. Puncture
The service warning light
comes on on the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function display locating
the wheel concerned.
Check the tyre pressures as soon as
possible. This check must be carried
out when the tyres are cold. The STOP warning light
comes on on the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction
display locating the wheel
concerned
.
Stop immediately, avoiding any sudden
movement of the steering wheel and
the brakes
.
Change the damaged wheel (punctured

Sensor(s) not detected or faulty
The service warning light
comes on on the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function display locating
the wheel or wheels which are not
detected or indicating a fault in the
system.
Have the faulty sensor(s) checked
by a CITROËN dealer. All repairs and changing of tyres
o n a w h e e l fi t t e d w i t h t h i s s y s t e m
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you
install a wheel which is not detect-
e d b y y o u r v e h i c l e ( e x a m p l e : fi t t i n g
of snow tyres), you must have the
system reinitialised by a CITROËN
dealer.
This system does not eliminate
the need to have the tyre pres-
sure checked regularly (refer to the
" T e c h n i c a l d a t a - § I d e n t i fi c a t i o n
features" section) to ensure that the
optimum dynamic performance of
the vehicle is maintained and pre-
vent premature wear of the tyres,
particularly in arduous driving con-
ditions (heavy load, high speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.

BRAKING ASSISTANCE SYSTEMS
Group of supplementary systems
which help you to obtain optimum
braking in complete safety in emer-
gency situations:
- the anti-lock braking system (ABS),
- the electronic brake force distri- bution (EBFD),
- the emergency braking assis- tance (EBA).
Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the
stability and manoeuvrability of your
vehicle 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
When braking in an emergency,
p r e s s v e r y fi r m l y w i t h o u t r e l e a s i n g
the pressure. If this warning light comes
on, accompanied by an au-
dible signal and a message
on the multi-function display,
it indicates a malfunction of the anti-
lock braking system which could
result in loss of control of the vehicle
when braking.
If this warning light comes on,
together with the STOP and
ABS warning lights, accom-
panied by an audible signal
and a message on the multifunction
display, 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.
In both cases, contact a CITROËN
dealer.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations. Emergency braking assistance
System which, in an emergency,
enables 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
i n c r e a s e i n b r a k i n g e f fi c i e n c y .
When braking in an emergency,

TRAJECTORY CONTROL SYSTEMS
Anti-skid regulation (ASR) and
electronic stability programme
(ESP)
The anti-skid regulation optimises
traction to prevent skidding of the
wheels, by acting on the brakes of the
driving wheels and on the engine.
The electronic stability programme
acts on the brake of one or more
wheels and on the engine to keep
the vehicle on the trajectory required
by the driver.
Activation
These systems are activated auto-
matically each time the vehicle is
started.
They come into operation in the event
of a grip or trajectory problem. T h i s i s i n d i c a t e d b y fl a s h i n g
of this warning light on the
instrument panel. Disarming
I n e x c e p t i o n a l c o n d i t i o n s ( s t a r t i n g a
vehicle which is bogged down, stuck
in snow, on soft ground, ...), it may
be advisable to disarm the ASR and
ESP systems, so that the wheels
can move freely and regain grip.
Press the "ESP OFF" button, lo-
cated in the centre of the fascia. Reactivation
These systems are reactivated au-
tomatically each time the ignition is
switched back on or from 30 mph
(50 km/h).
Press the "ESP OFF" button again
to reactivate them manually.
If this warning light comes
on on the instrument panel
and the indicator light on the
button comes on, this indi-
cates that the ASR and ESP
systems are disarmed. Operating fault
If this warning light comes
on, accompanied by an au-
dible signal and a message
on the multifunction display,
this indicates a malfunction of these
systems.
Have the systems checked by a
CITROËN dealer.

The correct functioning of these
systems depends on observation
of the manufacturer's recommen-
dations regarding the wheels (tyres
and rims), the braking components,
the electronic components and the
CITROËN assembly and operation
procedures.
After an impact, have these systems
checked by a CITROËN dealer.

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 "parking brake ap-
plied" 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 (e.g. starting
the engine), the parking brake can
automatically alter its force. This is
normal operation.

Dynamic emergency braking
In the event of a failure of the ve-
hicle’s main braking system or in
an exceptional situation (e.g. driver
taken ill, under instruction, etc) a
continuous pull on control A will 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
multifunction screen:
- "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"
actions on control A .
The dynamic emergency
braking must only be used in
exceptional circumstances.
