Before restarting, consult the table of tyre
pressures on the inside of the fuel filler flap
to ensure that the tyre pressure in all four
tyres is set correctly for the operating con-
ditions concerned.

Also observe the notes in the section on
tyre pressures (

G
Risk of accident
The tyre pressure loss warning system can
only give reliable warnings if you have set
the correct tyre pressure.
If an incorrect tyre pressure is set, these
incorrect values will be monitored.
A tyre with insufficient pressure results in
vehicle instability when driving, thus
increasing the risk of an accident.

Checking the tyre pressure electroni-
cally*
The tyre pressure monitor only functions if
the correct wheel electronics are fitted to all
wheels. These monitor the pressure in all four
tyres, which you have set when restarting the
tyre pressure monitor. The monitor warns you
when the pressure drops in one or more of
the tyres.
G
Risk of accident
The tyre pressure monitor does not warn
you of an incorrectly set tyre pressure. The
table on the inside of the fuel filler flap will
help you decide whether the tyre pressures
should be corrected.
