Under-inflation alert
This is given by 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 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.
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.
F If it is not possible to make this check
immediately, drive carefully at reduced
speed.
or
F In the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment).
The alert is maintained until the system
is reinitialised.
Reinitialisation
It is necessary to reinitialise the system every
time one or more tyre pressures are adjusted,
and after changing one or more wheels.
Before reinitialising the system, ensure
that the pressures of the four tyres are
correct for the use of the vehicle and in
line with the recommendations on the
tyre pressure label.
The under-inflation alert can only
be relied on if the reinitialisation of
the system has been done with the
pressures in the four tyres correctly
adjusted.
The under-inflation detection system
does not give a warning if a pressure is
incorrect at the time of reinitialisation.
