Tyre Under-Inflation Detection - CITROEN GRAND C4 PICASSO 2009-2010 Manual

TYRE UNDER-INFLATION
DETECTION
Sensors fi tted in each valve check
the tyre pressure during driving and
trigger a warning in the event of
malfunction (speed above 12 mph
(20 km/h).
VIII
The tyre under-infl ation detection
system is an aid to driving which
does not replace the vigilance or
responsibility of the driver.
Flat tyre
The service warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-

The STOP warning lamp
comes on in the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction

Stop immediately, avoiding any sudden
movement of the steering wheel and
the brakes.
Change the damaged wheel (punctured
or very defl ated tyre), and have the tyre
pressure checked as soon as possible.
Sensor(s) not detected or faulty
The service
lamp comes on in the

All repairs and changing of tyres
on a wheel fi tted with this system
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you in-
stall a wheel which is not detected
by your vehicle (example: fi tting
of snow tyres), you must have the
system reinitialised by a CITROËN
dealer.
This system does not eliminate
warning
the need to have the tyre pres-
sure checked regularly (refer to the
ac-
"Technical data - § Identifi cation
markings" section) to ensure that
the optimum
ance of the vehicle is maintained
and prevent premature wear of the
tyres, particularly in arduous driv-
ing conditions (heavy load, high
speed).
The tyre
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.
The tyre under-infl ation detection
system may experience temporary
interference due to radio-electric
