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.

SAFETY
134
The ESP/ASR systems offer
exceptional safety in normal
driving, but this should not en-
courage 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.

Emergency braking
If a failure of the ESP system is
signalled by the illumination 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 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 programme
(ESP) provides stability during emer-
gency 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 manual device can
release the parking brake.

LANE DEPARTURE WARNING SYSTEM
The lane departure warning sys-
tem cannot, in any circumstances,
replace the need for vigilance and
responsibility on the part of the
driver.
Activation
)
Press this button, the indicator lamp
comes on.
Deactivation
)
Press this button again, the indicator
lamp goes off.
The status of the system remains in the
memory when the ignition is switched
off.
Detection
You are warned by the vibration of the
driver's seat cushion:
- on the right-hand side, if the mark-
ing on the ground has been crossed
on the right,
- on the left-hand side, if the marking
on the ground has been crossed on
the left.
No warning is transmitted while the
direction indicator is active and for
approximately 20 seconds after the di-
rection indicator is switched off.
A warning may be transmitted if a direc-
tion marking (e.g. arrow) or non-standard
marking (e.g. graffi ti) is crossed.
Operating fault
The detection may be impeded:
- if the sensors are dirty (mud,
snow...),
- if the markings on the ground
are worn,
- if there is little contrast be-
tween the markings on the
ground and the road surface.
System which detects the involuntary
crossing of longitudinal traffi c lane mark-
ings on the ground (solid or broken
line).
Sensors, fi tted below the front bumper,
trigger a warning if the vehicle drifts
over a lane marking (speed higher than
50 mph (80 km/h)).
This system is particularly useful on
motorways and main roads. In the event of a malfunc-
tion, the service warning
lamp comes on, accompa-
nied by an audible signal
and a message in the screen.
Contact a CITROËN dealer or a qualifi ed
workshop.

BLIND SPOT SENSORS
This driving assistance system warns
the driver of the presence of another
vehicle in the blind spot angle of their
vehicle (areas masked from the driver's
fi eld of vision), as soon as this presents
a potential danger.
Operation
)
On switching on the ignition, or en-
gine running, press this button to
activate the function; the warning
lamp comes on.
This system is designed to im-
prove safety when driving and is
in no circumstances a substitute
for the use of the interior rear
view mirror and door mirrors. It
is the driver's responsibility to
constantly check the traffi c, to
asses the distances and relative
speeds of other vehicles and
to predict their movements be-
fore deciding whether to change
lane.
The blind spot sensor system
can never replace the vigilance
and responsibility of the driver.
Sensors fi tted in the front and rear bum-
pers monitor the blind spots. A warning lamp appears in the door
mirror on the side in question:
- immediately, when being overtaken,
- after a delay of about one second,
when overtaking a vehicle slowly.
