Driving
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 specified for the
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.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
This is signalled by the fixed
illumination of this warning lamp,
accompanied by an audible signal
and, depending on equipment, 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.
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.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not rely on just a visual check.
F Using a compressor, such as the one in the
temporary puncture repair kit, check the
pressures of the four tyres when cold.
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
Reinitialise the system after adjusting one or
more tyre pressures and after changing one or
more wheels.
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.
