Tyre Under-Inflation Detection - CITROËN C4 Handbook

Driving
Tyre under-inflation detection
System which automatically checks the
pressures of the tyres 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 if a drop in
pressure is detected in one or more tyres.
The tyre under-inflation detection system is an
aid to driving which 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 regularly
(including the spare wheel) and before
a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).
Driving with under-inflated tyres
increases fuel consumption.
The tyre pressures for your vehicle can
be found on the tyre pressure label.
The tyre pressures must be checked
when the tyres cold (vehicle stopped
for 1 hour or after driving for less then
6 miles (10 km) at moderate speed).
Otherwise, add 0.3 bar to the values
indicated on the label.
For more information on identification
markings, including the tyre pressure
label, refer to the corresponding
section.
