Tyre under-inflation detection
System which automatically checks the pressure of the tyres while driving.
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).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.

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.
be

fore 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.

Operating fault
Snow chains
The system does not have to be
reinitialised after fitting or removing
snow chains.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.
The new pressure settings registered are
considered to be reference values by the
system. The under-inflation alert is only
dependable if the system has been
reinitialised with all four tyres inflated to
the correct pressures.
be

fore doing anything to the system,
the pressures of the four tyres must be
checked and the system reinitialised.

Operating fault
You must stop as soon as it is safe to do so.
In either case, contact a CITRoËn dealer or a
qualified workshop. If this warning lamp comes on,
accompanied by an audible signal
and a message in the 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 in the
screen, it indicates a malfunction of
the electronic brake force distribution
which could result in loss of control of
the vehicle when braking.
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 efficiency.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations. When braking in an emergency, press
firmly without releasing the pressure.

Trajectory control systems
Anti-slip regulation (ASR)
and dynamic stability
control (DSC)
The anti-slip regulation (also known as traction
control) optimises traction to prevent skidding
of the wheels, by acting on the brakes of the
driving wheels and on the engine.
The electronic stability control 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 automatically
each time the vehicle is started.
They come into operation in the event of a grip
or trajectory problem.This is indicated by flashing of this
warning lamp in the instrument panel.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), if you are unable to make progress,
it may be advisable to temporarily deactivate
these systems, so that the wheels can spin
freely and allow the vehicle to move.

P
ress the "ESP OFF" button, located near
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 these systems are deactivated.
It is recommended that the systems be
reactivated as soon as possible.
Reactivation
These systems are reactivated automatically
each time the ignition is switched back on or
from 30 mph (50 km/h).
F

P
ress the "ESP OFF" button again to
reactivate them manually.
Operating fault
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 CITR
oËn


dealer or a qualified workshop.
The trajectory control systems offer
increased 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 is assured provided that
manufacturer's recommendations are
observed on:

dep

ending 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.
From approximately 12 mph (20 km/h)
this warning lamp flashes for two minutes
accompanied by an audible signal of increasing
volume. Once these two minutes have elapsed,
this warning lamp remains on until the driver and/
or the front passenger fastens their seat belt.
