Tyre Under-Inflation Detection; Under-Inflation Alert; Checking Tyre Pressures - PEUGEOT 301 Handbook

Safety

Tyre 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 four
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).

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.

Under-inflation alert

This warning is indicated by
continuous illumination of the light,
an audible signal and a message
displayed on the screen.
F Reduce speed immediately, avoid
excessive steering movements and sudden
braking.
F Stop 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 a simple 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. 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 warning remains active until the
system is reinitialised.
