sor may detect suffi cient light.
Therefore, the lighting will not
come on automatically.
Do not cover the sunshine sen-
sor, coupled with the rain sensor
and located in the centre of the
windscreen behind the rear view
mirror; the associated functions
would no longer be controlled.

TYRE UNDER-INFLATION DETECTION
System which automatically and continu-
ously checks the pressure of the tyres
while driving.
Sensors fi tted in each valve trigger a
warning in the event of problem (speed
above 12 mph (20 km/h)).
This warning lamp is displayed
on the instrument panel and/or a
message appears in the screen,
accompanied by an audible signal,
to identify the wheel concerned.

Under-infl ated tyre
The STOP
warning lamp
comes on and/or this warn-
ing lamp is displayed on the
instrument panel, accompa-
nied by an audible signal and
a message in the screen iden-
tifying the wheel concerned.


)
Stop as soon as it is safe to do so,
avoiding any sudden movement of
the steering wheel and the brakes.

)
Repair or change the damaged
wheel (punctured or very defl ated
tyre), and have the tyre pressure
checked as soon as possible.

Puncture

Sensor(s) not detected or faulty
A message appears in the screen, ac-
companied by an audible signal, to
identify the wheel or wheels which are
not detected or to indicate a malfunc-
tion in the system.
Contact a CITROËN dealer or a quali-
fi ed workshop to replace the faulty
sensor(s).
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.
If your vehicle is equipped with
a spare wheel, this is not fi tted
with a sensor. All repairs and changing of tyres
on a wheel fi tted with this sys-
tem must be carried out by a
CITROËN dealer or a qualifi ed
workshop.
If, when changing a tyre, you
install a wheel which is not de-
tected by your vehicle (example:
fi tting of snow tyres), you must
have the system reinitialised by
a CITROËN dealer or a qualifi ed
workshop.
The tyre under-infl ation detec-
tion system is an aid to driving
which does not replace the need
for the driver to be vigilant or to
drive responsibly. This system does not avoid the
need to have the tyre pressures
checked regularly (refer to the
"Identifi cation markings" sec-
tion) to ensure that the optimum
dynamic performance of the ve-
hicle is maintained and prevent
premature wear of the tyres, par-
ticularly in arduous driving condi-
tions (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 detec-
tion system may experience
temporary interference due to
electro-magnetic emissions on a
frequency close to that used by
the system.


)
Check the tyre pressures as soon
as possible.
This check must be carried out when
the tyres are cold.

TRAJECTORY CONTROL SYSTEMS

Anti-slip regulation (ASR) and electronic stability programme(ESP)


The anti-slip regulation (also known as
Traction Control) optimises traction to
prevent skidding of the wheels, by act-
ing 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, 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)

Your vehicle has a system to help driving
on snow: Intelligent Traction Control.
This automatic system continuously
checks for 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, Intelligent Traction
Control
takes over from the ASR
sys-
tem, limiting the amount of wheel slip to
provide the best traction and trajectory
control, even without snow tyres and
with or without chains.
In extremely severe conditions (snow
on top of ice, sand, deep mud…), it can
be useful to deactivate the ESP/ASR

systems to allow a degree of wheel spin
and so recover grip.

Deactivation
In exceptional conditions (starting a ve-
hicle which is bogged down, stuck in
snow, on soft ground...), it may be ad-
visable to deactivate the ASR and ESP
systems, so that the wheels can move
freely and regain grip.


)
Press the "ESP OFF"
button, located
on the left below the steering wheel.

If this warning lamp comes on
in the instrument panel and
the indicator lamp in the button
comes on, this indicates that
the ASR and ESP systems are
deactivated.

8
SAFETY
130
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 is assured provided
that manufacturer's recommen-
dations are observed on:


- wheels (tyres and rims),

- braking components,

- electronic components,

- assembly and repair proce-
dures.
After an impact, have these sys-
tems checked by a CITROËN
dealer or a qualifi ed workshop.

Reactivation
These systems are reactivated automat-
ically 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 lamp comes on,
accompanied by an audible
signal and a message in the
screen, this indicates a fault
with these systems.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
Operating fault EMERGENCY OR ASSISTANCE CALL

This system allows you to make an
emergency or assistance call to the
emergency services or to the dedicated
CITROËN service.

SEAT BELTS

Front seat belts


The front seat belts are fi tted with a pre-
tensioning and force limiting system.
This system improves safety in the front
seats in the event of a front or side im-
pact. Depending on the severity of the
impact, the pretensioning system in-
stantly tightens the seat belts against
the body of the occupants.
The pretensioning seat belts are active
when the ignition is on.
The force limiter reduces the pressure
of the seat belt on the chest of the oc-
cupant, so improving their protection.











Fastening


)
Pull the strap, then insert the tongue
in the buckle.

)
Check that the seat belt is fastened
correctly by pulling the strap.


Unfastening


)
Press the red button on the buckle.

)
Guide the seat belt as it reels in.
The corresponding warning lamp 1
or 2

comes on in red on the seat belt and pas-
senger's front airbag warning lamps dis-
play, accompanied by an audible signal
and a message in the screen, if the seat
belt is not fastened or is unfastened.

From approximately 12 mph (20 km/h)
this warning lamp fl ashes for two min-
utes accompanied by an audible signal
of increasing volume. Once these two
minutes have elapsed, this warning
lamp remains on until the driver and/or
the front passenger fastens their seat
belt.
