19
Warning/indicator lampStateCause Action/Observations
Power steering Fixed. The power steering has a fault. Drive carefully at reduced speed.
Have it checked in the dealer network or by a qualified
workshop.
Under-inflation Fixed. The pressure in one or more of the
tyres is too low. Check the pressure of the tyres as soon as possible.
This check should preferably be carried out when the
tyres are cold.
+ Flashing then fixed,
accompanied by the
Service warning lamp.
The tyre pressure monitoring system
has a fault or no sensor is detected
on one of the wheels. Under-inflation detection is not assured.
Have the system checked in the dealer network or by
a


qualified workshop.
Airbags Temporarily on. This warning lamp comes on for a
few seconds when you turn on the
ignition, then goes off. This warning lamp should go off when the engine is
started.
If it does not go off, contact the dealer network or a
qualified workshop.
Fixed. One of the airbag or seat belt
pyrotechnic pretensioner systems has
a fault. Have them checked in the dealer network or by a
qualified workshop.

Tyre under-inflation
d
etection
The tyre under-inflation detection system
is an aid to driving which 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 worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The inflation pressures defined for your
vehicle can be found on the tyre pressure
label.
Tyre pressure 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, add 0.3 bar to the values
indicated on the label.
For more information on Identification
markings , including the tyre pressure
label, refer to the corresponding section.
Under-inflation alert
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres. This warning is indicated by
continuous illumination of the lamp,
an audible signal and, depending on
the equipment installed, a message
displayed on the screen.
In the event of a problem on one of the tyres,
the symbol or the message appears, according
to equipment, to identify it.

educe speed immediately, avoid excessive
steering movements and sudden braking.

top as soon as it is safe to do so.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not rely on just a visual check.

Driving

F If you have a compressor (such as the one in the temporary puncture repair kit) check
the pressures of the four tyres when cold.
If it is not possible to carry out this check
straight away, drive carefully at reduced
speed.
or
F

I
n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment).
The alert is maintained until the tyre or
tyres concerned is reinflated, repaired or
replaced.
The spare wheel (space-saver type or a
steel rim) does not have a sensor.
Operating fault
The flashing and then fixed
illumination of the under-inflation
warning lamp accompanied by the
illumination of the Ser vice warning
lamp indicates a fault with the
system.
In this case, the pressure in the tyres is no
longer monitored. This alert is also displayed when one or
more wheels is not fitted with a sensor
(for example, a space-saver or steel spare
wheel).
Go to a member of the dealer network
or a qualified workshop
to have the
system checked or, following the repair
of a puncture, to have the original wheel,
equipped with a sensor, refitted.
Any tyre repair or replacement on a wheel
fitted with this system must be carried
out by the dealer network or a qualified
workshop.
If after changing a tyre, a wheel is not
detected by your vehicle (fitting snow tyres
for example), you must have the system
reinitialised in the dealer network or by a
qualified workshop.

Temporary puncture
repair kit
This kit comprises a compressor and a sealant
cartridge.
It allows the temporary repair of a tyre.
You are then able to go to the nearest garage.
It is designed to repair most punctures
which could affect the tyre, located on the
tyre tread or shoulder.
Its compressor can be used to check and
adjust the pressure of the tyre.
Tyre under-inflation detection
If the vehicle is fitted with tyre under-
inflation detection, the under-inflation
warning lamp will remain on after the
wheel has been repaired until the system
is reinitialised by a dealer or a qualified
workshop.
The vehicle's electric system allows the
connection of the compressor for long
enough to inflate a tyre after a puncture
repair. Only
the 12 V socket at the front of
the vehicle allows the compressor to be
connected for long enough to repair or
inflate the vehicle tyre.
The other 12 V sockets of the vehicle
are not designed to be used with the
compressor.
Access to the kit Composition of the kit
1.
12 V compressor, with built-in pressure
gauge.
2. Bottle of sealant, with built-in hose.
3. Speed limit sticker.
Repair procedure

traffic and apply the parking brake.

Identification markings
Various visible markings for the identification of
your vehicle.
A. Vehicle identification number (V.I.N.),
under the bonnet.
The number is engraved on the body structure.
B. Vehicle identification number (V.I.N.), on
the dashboard.
The number is on a label, visible through the
windscreen. C. Manufacturer's label.
This tamperproof label is affixed to the driver's
door aperture.
It bears the following information:
-

t
he name of the manufacturer,
-

t
he European Whole Vehicle Type Approval
number,
-

t
he vehicle identification number (V.I.N.),
-

t
he gross vehicle weight (GV W)
-

t
he maximum authorised vehicle + trailer
weight (the Gross Train Weight or GTW),
-

t
he maximum weight on the front axle,
-

t
he maximum weight on the rear axle.
D. Tyres/paint code label.
This label is affixed to the driver's door
aperture.
It bears the following information on the tyres:
-

t
he tyre pressures, unladen and laden,
-

t
he tyre specification, made up of the
dimensions and type as well as the load and
speed indices,
-

t
he spare tyre pressure.
It also indicates the paint colour code. The vehicle may be originally equipped
with tyres with higher load and speed
indices than those indicated on the label,
without affecting inflation pressure.
Checking tyre pressures
The tyre pressures should be checked when
cold at least monthly.
The pressures given on the label are valid for
cold tyres. If you have driven for more than 10
minutes or more than 6 miles (10 kilometres)
at more than around 30 mph (50 km/h), the
tyres will be warm; in this case 0.3 bar (30 kPa)
should be added to the pressures given on the
label. Never reduce the pressure of a warm tyre.
Low tyre pressures increase fuel
consumption.
