Driving safely
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).
TYRE UNDER-INFLATION DETECTION
Under-inflation alert
This is given by fixed
illumination of this warning lamp,
accompanied the display of a
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 every
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.
message,depending on equipment.
F Reduce speed immediately, avoid
excessive steering movements and
sudden braking
F Stop the vehicle 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 satisfy yourself with just a visual
check.
Driving with under-inflated tyres increases
fuel consumption.
F In the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment),
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).
or
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,
or
F if it is not possible to make this check
immediately, drive carefully at reduced
speed.
Otherwise (when hot), add 0.3 bar to the
pressures shown on the label.
the alert is maintained until the system
is reinitialised.
