Under-inflation detection
The system monitors the pressures in 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 need for vigilance
on the part 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 pressures of the tyres while driving.

n the event of a puncture, use the

The alert is maintained until the system
is reinitialised.
Reinitialisation
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.
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.
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.

Electronic Stability Control (ESC) incorporating
the following systems:
-
a
nti-lock braking system (ABS) and the
electronic brake force distribution (EBFD),

-

d
ynamic stability control (DSC).
Electronic stability control (ESC)
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
These systems improve the stability and
manoeuvrability of your vehicle when braking
and contribute towards better control in
corners, in particular on poor or slippery road
surfaces.
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.
Traction control (TRC)
This system 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, this system 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.

Illumination of this warning lamp,
accompanied by an audible signal,
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
Illumination of this warning lamp,
accompanied by an audible signal,
indicates that there is a fault with
the ABS system, 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 vibration of the brake
pedal.
In emergency braking, press
very firmly without releasing
the

pressure.
Yo u must stop as soon as it is safe to do so.
Contact a CITROËN dealer or a qualified
workshop as soon as possible.
Dynamic stability control (DSC)
and traction control (TRC)
Activation
These systems are activated automatically
each time the vehicle is started.
As soon as they detect a problem of grip or
trajectory, these systems act on the operation if
the engine and brakes.
Activation of the DSC system is
signalled by the flashing of this
indicator lamp in the instrument panel,
accompanied by an audible signal.
Activation of the TRC system is
signalled by the flashing of this
indicator lamp in the instrument panel.
Drive carefully at reduced speed, and contact a
CITROËN dealer or a qualified workshop.
Safety

107
The TRC and DSC systems offer
increased safety in normal driving, but
should not encourage the driver to take
extra risks or drive at high speed.
The correct operation of these
systems depends on observation of
the manufacturer's recommendations
regarding the wheels (tyres and rims),
the braking components, the electronic
components and the assembly and
repair procedures used by CITROËN
dealers.
After an impact, have the system
checked by a CITROËN dealer or a
qualified workshop.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), it may be advisable to deactivate the
DSC and TRC systems, so that the wheels can
spin freely and regain grip.
Operating fault
However, it is recommended that theses
systems be reactivated as soon as possible.F

P

Safety

111
Unwanted triggering of the system
It is possible for the system to detect a risk of
imminent collision and start working, in the
following conditions in particular:
-
d
etection of an object located close to the
outer edge of a bend (safety barrier, lamp
post or road sign),
-

d
etection of an object located at the top or
bottom of a steep slope,
-

d
etection of reflective objects (central
reservation...) in the road,
-

d
etection of the upper bar of a bridge or a
traffic light gantry,
-

d
etection of a vehicle on a bend travelling
in the other direction,
-

d
etection of a vehicle traveling in the other
direction, at a crossroads, when your
vehicle is turning left or right,
-

i
f the vehicle ahead of you sends up water
or snow,
-

i
f your vehicle stops very close to a wall or
other vehicles,
-

w
hen your vehicle closes rapidly on the
vehicle ahead,
-

i
f the vehicle is raised or lowered,
-
i

f the vehicle passes through a plastic curtain,
-

i
f driving through mist or smoke,
-

i
f the sensor is misaligned (following
replacement after a collision).
Never leave accumulations of snow or
any object projecting above the bonnet
or in front of the roof: this might fall into
the field of vision of the sensor and
generate a detection.
Operating limits
The system only detects
vehicles (cars, lorries)
that are stationary or moving in the same
direction as your vehicle. In difficult weather conditions (very
heavy rain, snow, fog, hail...), braking
distances increase, which can reduce
the ability of the system to avoid a
collision.
The driver must therefore remain
particularly vigilant.
The system is not triggered or is interrupted if
the driver:
-

a
ccelerates strongly (even if the speed
limiter is on),
-

o
r turns the steering wheel suddenly
(avoiding manoeuvre).
Detection capability is less effective if:
-

y
ou are driving on roads with pronounced
bends and/or on roads in poor condition,
-

y
our vehicle is excessively loaded, as
this changes the horizontal attitude of the
vehicle. It does not detect small vehicles
(bicycles, motorcycles), pedestrians or
animals, nor non-reflective stationary
objects.
