 If you have fi tted wheels that
are not equipped with tyre defl a-
tion detection (wheels with snow
tyres, etc.), contact a CITROËN
dealer.
The defl ation detection system is a
driving aid, but which does not ab-
solve the driver from the need to be
vigilant and responsible.
This system does not dispense with
the requirement to check the tyres
on a regular basis (see "Vehicle
identifi cation"), to make sure that
the vehicle is behaving correctly
and to avoid premature tyre wear
arising from driving too fast etc.
Do not forget to check the pressure
in the spare wheel.
Any repair or replacement of a tyre
on a wheel that is equipped with
a sensor must be carried out by a
CITROËN dealer.
The system may suffer from tempo-
rary interference caused by radio
transmissions on neighbouring fre-
quencies.

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 instrument panel
screen, 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 lamp comes
on, together with the STOP
and ABS warning lamps,
accompanied by an audible
signal and a message on the instru-
ment panel screen, 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 (also known
as Traction Control) optimises trac-
tion 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 lamp on the
instrument panel. Deactivation
In exceptional conditions (starting a
vehicle which is bogged down, stuck
in snow, on soft ground...), it may be
advisable to deactivate 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 dash-
board.
If this warning lamp comes
on in the instrument panel
and the indicator lamp on the
button comes on, this indi-
cates that the ASR and ESP
systems are deactivated.
Snow driving assistance
(SNOW MOTION)
Your vehicle has a system to help
driving on snow:
SNOW MOTION.
This automatic system continuously
checks for situations of diffi cult sur-
face adhesion that could make it dif-
fi cult to move off or make progress
on deep fresh snow or compacted
snow.
In these situations, the SNOW
MOTION system takes over from
the ASR system by optimising the
amount of wheel slip to provide the
best traction and trajectory control,
even without snow tyres and with or
without chains. For vehicles with Hydractive III+
suspension, manual adjustment of
ground clearance to the intermediate
position improves further the ability
to make progress in deep snow (see
the relevant paragraph).
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.

SEAT BELTS
Front seat belts
The front seat belts are fi tted with
a pretensioning system and force
limiter.
This system improves safety in the
front seats in the event of a front
impact.
Depending on the seriousness of the
impact, the pretensioning system
instantly tightens the seat belt
against the body of the occupant. Fastening

 Pull the belt down in front of you
in a steady movement, making
sure that it does not become
twisted.

 Press the fastening into its
buckle.

 Check that it is properly secured
and that the automatic locking
mechanism operates correctly
by pulling sharply on the belt
strap.

 The abdominal part of the strap
should be positioned as low
down as possible in the lap and
as tight as possible.

 The chest part should be posi-
tioned if possible in the channel
of the shoulder.
Each belt has a reel that adjusts its
length automatically to the girth of
the seat occupant.
The pretensioning seat belts are
active when the ignition is on.
The force limiter reduces the pres-
sure of the seat belt against the
chest of the occupant, so increasing
his protection.
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 manu-
ally.
Operating fault
If this warning lamp comes
on, accompanied by an au-
dible signal and a message
on the multifunction screen,
this indicates a malfunction of these
systems.
Have the systems checked by a
CITROËN dealer.
The ESP/ASR systems offer exce-
ptional 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.
