TYRE PRESSURE LOSS WARNING (2/9)
1
SYSTEM A
Operating principle
This system detects a loss of pressure
in one of the tyres by measuring the
wheel speed while driving.
Warning light
 1 comes on to
alert the driver in the event of insuffi-
cient pressure (deflated wheel, punctu-
red tyre, etc.).
Operating conditions
The system should be reset with an
inflation pressure equal to that given
on the tyre inflation pressure label.
Otherwise it risks not giving a reliable
warning in the event of a significant loss
of pressure. Please refer to the informa-
tion on “Tyre pressures” in Section 4.
In the following situations, the system
risk coming into action late or not func-
tioning correctly:
– system not reset after reinflation or any operation on the wheels;
– system badly reset: different inflation pressures from the recommended
pressures;
– significant change in load or distribu- tion of load on one side of the vehi-
cle;
– sporty driving with strong accelera- tion;
– driving on snowy or slippery surface; – driving with snow chains;
– fitting a single new tyre;
– use of tyres not approved by the net-
work.
– ...
This function is an addi-
tional driving aid.
However, the function does
not take the place of the
driver. It cannot, therefore, under
any circumstances replace the vig-
ilance or the responsibility of the
driver.
Check the tyre pressures, including
the emergency spare wheel, once a
month.

TYRE PRESSURE (2/2)
Tyre safety and use of snow chains:
Refer to the information on “Tyres” in
Section 5 for the servicing conditions
and, depending on the version, the use
of chains.
For your safety, please re-
spect the speed limit.
When they need to be re-
placed, only tyres of the
same make, size, type and profile
should be used on a single axle.
They must: either have a load ca-
pacity and speed rating at least
equal to those of the original
tyres, or conform to those recom-
mended by an authorised dealer.
Failure to heed these instructions
could endanger your safety and
affect your vehicle’s roadworthi-
ness.
Risk of loss of control of the ve-
hicle.

Tyre pressuresAdhere to the tyre pressures. The tyre
pressures should be checked at least
once a month and additionally before
any long journey (refer to the label af-
fixed to the edge of the driver’s door).
The pressures should be checked cold:
ignore higher pressures which may be
reached in hot weather or following a
high speed journey.Vehicle fitted with a tyre pressure
loss warning system
If under-inflated (puncture, low pres-
sure, etc.), the warning light

on the instrument panel comes on.
See “Tyre pressure loss warning” in
Section 2.
Fitting new tyres
For safety reasons, this op-
eration must be carried out
by a specialist. Fitting differ-
ent tyres may change your
vehicle as follows:
– it may mean that your vehicle no longer conforms to current regu-
lations;
– it may change the way it handles when cornering;
– it may cause the steering to be heavy;
– it may affect the use of snow chains.
If the pressures cannot be checked
when the tyres are cold, increase the
pressures from 0.2 to 0.3 bar (or 3 PSI).
Never deflate a hot tyre.
Changing wheels around
TYRES (2/3)
Please be aware that a
poorly tightened or miss-
ing valve cap can make the
tyres less airtight and lead
to pressure loss.
Always use valve caps identical to
those fitted originally and tighten
them fully.
Incorrect tyre pressures
lead to abnormal tyre wear
and unusually hot running.
These are factors which
may seriously affect safety and lead
to:
– poor road holding,
– risk of bursting or tread separa- tion.
The pressure depends on the load
and the speed of use. Adjust the
pressure according to the condi-
tions of use (refer to the label affixed
to the edge of the driver’s door).
The front and rear wheels
have different dimensions.
For safety reasons, it is not
permitted to switch the front
wheels (tyres and/or rims) with the
rear wheels.

TYRES (3/3)
Studded tyres
This type of equipment may only be
used for a limited period and as laid
down by local legislation. It is neces-
sary to observe the speed specified by
current legislation.
These tyres must, at a minimum, be
fitted to the two front wheels.
Chains may only be fitted
to tyres of the same size
as those originally fitted to
your vehicle.
In all cases, we would recommend
that you contact an approved dealer
who will be able to advise you on
the choice of equipment which is
most suitable for your vehicle.
Snow or winter tyres
We would recommend that these be
fitted to all four wheels to ensure that
your vehicle retains maximum adhe-
sion.
Warning: These tyres sometimes have
a specific direction of rotation and a
maximum speed index which may be
lower than the maximum speed of your
vehicle.
16” wheels cannot be
fitted with chains.
If you wish to fit snow
chains, you must use spe-
cial equipment .
Consult an approved Dealer.
Use in winter
Chains
For safety reasons, only fit chains
on the rear axle.
Chains cannot be fitted to tyres which
are larger than those originally fitted to
the vehicle.
17” wheels cannot be
fitted with chains.
To obtain equivalent special
equipment, consult an ap-
proved dealer.
