Under-Inflation Detection - CITROËN C-ZERO Handbook

Safety

Under-inflation detection

System which continuously and automatically
checks the pressures of the four tyres after
switching on the ignition.
A pressure sensor is located in the valve of
each tyre.
The system triggers an alert if a drop in
pressure is detected in one or more tyres,
compared to the reference pressure registered
in the system. This reference pressure must be
reinitialised every time the tyre pressures are
adjusted or a wheel changed.
The system operates on condition that sensor
identifiers have first been memorised in the
system by a CITROËN dealer or a qualified
workshop.
You can memorise two sets of tyres
(for example: wheels with "standard" tyres and
wheels with "winter" 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 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 (see
the "Identification markings" section).
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.
