Tyre Under-Inflation Detection - CITROËN C5 Handbook

Driving
Maintenance
Before doing any work under the
bonnet, deactivate the Stop & Start
system to avoid the risk of injury related
to an automatic change to START
mode.
This system requires the use of a 12 V battery
of specific technology and characteristics
(reference numbers available from a CITROËN
dealer or a qualified workshop).
Fitting a battery not listed by CITROËN would
introduces the risk of faults with the system.
The Stop & Start system makes use of
an advanced technology. All work on
this type of battery must only be carried
out by a CITROËN dealer or a qualified
workshop.

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 (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.
