Driving
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.
Under-inflation detection does not replace
the need for vigilance on the part of the
driver.
This system does not avoid the need
to regularly check the tyre pressures
(including the spare wheel) as well as
before a long journey.
Driving with under-inflated tyres,
particularly in adverse conditions (heavy
load, high speed, long journey):
- worsens road-holding,
- lengthens braking distances,
- causes premature wear of the tyres,
- increases fuel consumption.
The inflation pressures defined for your
vehicle can be found on the tyre pressure
label.
For more information on the
Identification markings, refer to the
corresponding section.
Checking tyre pressures
This check should be done when the tyres
are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10 km)
at moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.
Under-inflation alert
This is signalled by continuous
illumination of this warning lamp,
an audible signal and the display of
a message.
F Reduce speed immediately, avoid excessive
steering movements and avoid 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 rely on just a visual check.
F If it is not possible to make this check
immediately, drive carefully at reduced
speed.
F In the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment).
The alert is kept active until the system is
reinitialised.
Reinitialisation
The system must be reinitialised after any
adjustment to the pressure of one or more
tyres, and after changing one or more wheels.
F Using a compressor, such as the one in the
temporary puncture repair kit, check the
pressures of the four tyres when cold.
Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written
on the tyre pressure label.
Check the pressures of the four tyres
before performing the reinitialisation.
The system does not advise if a pressure
is incorrect at the time of reinitialisation.
