Tyre under-inflation detection
The system monitors the pressures on the four
tyres, once the vehicle is moving.
It compares the information given by the four
wheel speed sensors with reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres. The under-inflation detection system
does not replace the vigilance or the
responsibility of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres impairs
road holding, extends braking distances
and causes premature tyre wear,
particularly under arduous condition
(high loading, high speed, long journey).
System which automatically checks the pressure of the tyres while driving.
The inflation pressures defined for
your vehicle can be found on the tyre
pressure label.
See the "Identification markings"
section.
Tyre pressures should be checked
when the tyres are "cold" (vehicle
stopped for 1 hour or after a journey of
less than 6 miles (10 km) at moderate
speeds).
Other wise (when hot), add 0.3 bar to
the pressures shown on the label.
Driving with under-inflated tyres
increases fuel consumption.

Under-inflation alertReinitialisation
Before reinitialising the system, ensure
that the pressures of the four tyres are
correct for the use of the vehicle and in
line with the recommendations on the
tyre pressure label.
The under-inflation detection system
does not give a warning if a pressure is
incorrect at the time of reinitialisation.
This is given by fixed illumination of
this warning lamp, accompanied by
an audible signal and the display of a
message.
It is necessary to reinitialise the system every
time one or more tyre pressure is adjusted, and
after changing one or more wheels.
A label attached to the middle pillar, driver's
side, gives a reminder of this.

n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment),
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not satisfy yourself with just a visual
check. The alert is maintained until the system
is reinitialised.

The new pressure settings registered are
considered to be reference values by the
system.
Operating fault
The flashing and then fixed illumination of the
under-inflation warning lamp accompanied
by illumination of the "service" warning lamp
indicates a fault with the system.
In this case, under-inflation monitoring of the
tyres is no longer assured.
Have the system checked by a CITROËN
dealer or a qualified workshop.
Before doing anything to the system,
the pressures of the four tyres must be
checked and the system reinitialised.
The under-inflation alert can only be
considered reliable if reinitialisation of
the system is done with the the four tyre
pressures correctly set.
Snow chains
The system does not have to be
reinitialised after fitting or removing
snow chains.

Electronic stability control (ESC)
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking
and provides improved control in corners, in
particular on poor or slippery road sur faces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
manages the braking pressure wheel by wheel.
Emergency braking assistance
In an emergency, this system enables you to
reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance.
It is triggered according to the speed at which
the brake pedal is pressed. This is felt by a
reduction in the resistance of the pedal and an
increase in the effectiveness of the braking.
Anti-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.

When this warning lamp comes on,
coupled with the STOP warning lamp,
accompanied by an audible signal and a
message, it indicates that there is a fault
with the electronic brake force distribution
(EBFD), which could cause loss of control
of the vehicle when braking.
Operation
When this warning lamp comes on,
accompanied by an audible signal
and a message, it indicates that there
is a fault with the ABS, which could
cause loss of control of the vehicle
when braking.
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)When changing wheels (tyres and rims),
make sure that these are approved for
your vehicle.
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
In emergency braking, press
very firmly without releasing the
pressure.
You must stop as soon as it is safe to do so.
In both cases, contact a CITROËN dealer or a
qualified workshop.

Seat belts
Front seat belts
The front seat belts are fitted with a
pretensioning and force limiting system.
This system improves safety in the front
seats in the event of a front or side impact.
Depending on the severity of the impact, the
pretensioning system instantly 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 occupant, so
improving their protection.Fastening
