AUTOMATIC ADJUSTMENT OF THE DIRECTIONAL HEADLAMPS
In order to avoid causing a nuisance
to other road users, this system cor-
rects the height of the xenon head-
lamps beam automatically and when
stationary, in relation to the load in
the vehicle. If a malfunction oc-
curs, this warning light
is displayed on the
instrument panel, ac-
companied by an au-
dible signal and a message on the
multifunction display.
The system then places your head-
lamps in the lowest position.
Do not touch the xenon headlamps.
Consult a CITROËN dealer.
DIRECTIONAL LIGHTING
When the dipped or main beam
headlamps are on, this function
enables the light beam to follow the
direction of the road.
The use of this function, coupled
with the xenon headlamps only,
considerably improves the quality of
your lighting when cornering.

TYRE UNDER-INFLATION DETECTION
Sensors ﬁ tted in each valve check
the tyre pressure during driving and
trigger a warning in the event of
malfunction (speed above 12 mph
(20 km/h)).
Flat tyre The tyre under-inﬂ ation detection
system is an aid to driving which
does not replace the need for the
driver to be vigilant or to drive re-
sponsibly. 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 instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function display locating
the wheel concerned.
Stop immediately, avoiding any sud-
den movement of the steering wheel
and the brakes.
Change the damaged wheel (punctured
or very deﬂ ated tyre), and have the tyre
pressure checked as soon as possible.
Sensor(s) not detected or faulty
The service warning light
comes on on the instru-
ment panel, accompa-
nied by an audible signal
and a message on the
multifunction display lo-
cating 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
on a wheel ﬁ tted with this system
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you in-
stall a wheel which is not detected
by your vehicle (example: ﬁ tting
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
"Technical data - § Identiﬁ cation
features" section) to ensure that
the optimum dynamic perform-
ance of the vehicle is maintained
and prevent premature wear of the
tyres, particularly in arduous driv-
ing conditions (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.
The tyre under-inﬂ ation detection
system may experience temporary
interference due to radioelectric
emissions on a frequency close to
that used by the system.
This message is also displayed
when one of the wheels is away
from the vehicle (being repaired) or
when one or more wheels without a
sensor are ﬁ tted.
The spare wheel is not ﬁ tted with a
sensor.

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 assist- ance (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,
press very ﬁ rmly without releasing
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 re-
sult 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 recommenda-
tions. 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
increase in braking efﬁ ciency.
When braking in an emergency,
press ﬁ rmly without releasing the
pressure.

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. This is indicated by ﬂ ashing
of this warning light on the
instrument panel. Disarming
In exceptional conditions (starting 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 ESP/ASR systems offer ex-
ceptional safety in normal driving,
but this should not encourage the
driver to take extra risks or drive at
high speed.
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.
