Under-inīation detection
This system automatically monitors the tyre
pressure while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a drop in the pressure of one or more
tyres.
This system does not eliminate 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
handling, extends braking distances and
causes early tyre wear, particularly in
adverse conditions (heavy loads, high
speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The tyre pressure specifications for your
vehicle can be found on the tyre pressure
label.
Tyre pressure 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).
Otherwise, add 0.3
bar (30 kPa) to the
values indicated on the label.
For more information on Identification
markings, including the tyre pressure
label, refer to the corresponding section.
Under-inflation alert
This is indicated by continuous
illumination of this warning lamp,
an audible signal and, depending
on equipment, the display of a
message.
- In the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment).
or
- 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
- if it is not possible to make this check
immediately, drive carefully at reduced
speed.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not rely on a simple visual check.
The alert continues until the tyre or tyres
concerned are reinflated, repaired or
replaced.
The spare wheel (space-saver or a steel
rim type) does not have a sensor.
In the event of a problem with one of the tyres,
depending on equipment, the symbol or the
message appears to identify it.
- Reduce speed immediately, avoid excessive
steering movements and sudden braking.
- Stop as soon as it is safe to do so.
