Directional headlamps
This lighting function automatically
improves forward vision when cor-
nering. Lane departure warning
system
Above 50 mph, this system is activated
automatically if you inadvertently wander
from your lane.
Parking sensors, front/rear
This system warns you if an obsta-
cle is detected when manoeuvring
the vehicle.
Guide-me-home lighting
The headlamps stay on for a short
period after switching off the ignition.

Vehicle maintenance
When washing your vehicle, hold
the end of the high pressure nozzle
more than 30 centimetres from the
self-adhesive fi lm fi nishers.
Temporary puncture repair kit
This kit is a complete system, consis-
ting of a compressor and an integral
sealant product, for the temporary re-
pair of a tyre.

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)).
Under-infl ated tyre The tyre under-infl ation detection
system is an aid to driving which
does not replace the vigilance or
responsibility of the driver. Puncture
The service warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen 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 lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen 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
lamp comes on in the
instrument panel, ac-
companied by an audible
signal and a message on
the multifunction screen
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
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 avoid the
need to have the tyre pressures
checked regularly (refer to the
"Technical data - § Identifi cation
markings" section) to ensure that
the optimum dynamic performance
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 electro-magnetic
signals 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:
- anti-lock braking system (ABS),
- electronic brake force distribution (EBFD),
- emergency braking assistance (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 lamp comes
on, accompanied by an au-
dible signal and a message
on the multifunction screen,
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 lamp comes
on, together with the STOP
and ABS warning lamps,
accompanied by an audible
signal and a message on the multi-
function screen, it indicates a mal-
function of the electronic brake force
distribution which could result in loss
of control of the vehicle when brak-
ing.

You
must
stop as soon as it is
safe to do so.
In either case, 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.

 Switch on the compressor by
moving the switch B to posi-
tion "I" until the tyre pressure
reaches 2.0 bars. If after around 5 to 7 minutes the
pressure is not attained, this indicates
that the tyre is not repairable; contact
a CITROËN dealer for assistance.

 Remove the kit and rescrew the
cap on the white pipe. Take care
to avoid staining your vehicle
with traces of fl uid. Keep the kit
to hand.


Drive immediately for approximate-
ly three miles (fi ve kilometres), at
reduced speed (between 15 and
35 mph [20 and 60 km/h]), to plug
the puncture.


 Stop to check the repair and the
tyre pressure using the kit. Checking tyre pressures/
Infl ating accessories
You can use the compressor, with-
out injecting the product, for the
routine check and adjustment of
the tyre pressures on your vehicle.
It can also be used to infl ate other
items such as a ball or bicycle tyre.
Turn the selector to the "AIR" posi-
tion, connect the black pipe to the
valve of the wheel or the item to
be infl ated with, if necessary, one
of the connectors supplied with the
kit, then follow the remainder of the
procedure below until the kit is re-
moved.

 Turn the selector A to
the "AIR" position:

 Connect the black pipe D to the
valve of the wheel.

Use the tyre pressures recom-
mended by CITROËN.
Check the tyre pressures when the

tial to use the tyre sizes that are
recommended for your vehicle.
