Under-Inflation Detection - PEUGEOT 5008 Handbook

Driving

Under-inflation detection

System which automatically checks the
pressures of the tyres while driving.
The system monitors the pressures in the four
tyres, once the vehicle is moving.
It compares the information given by the 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.
The under-inflation detection system does
not replace the need for vigilance on the
part 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 worsens
road-holding, lengthens braking distances,
causes premature wear of the tyres,
particularly in adverse conditions (heavy
loads, high speeds, long journeys).
174
Driving with under-inflated 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.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
This warning is indicated by
continuous illumination of this lamp,
an audible signal and, depending on
the equipment installed, a message
displayed on the screen.
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 case 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.
