Tyres and wheels
tyres is set correctly for the operating con-
ditions concerned.
Also observe the notes in the section on

tyre pressures ( page 184).

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.
Make sure that the key is in position 2 in
X
the ignition lock.
The standard display appears in the multi-
function display ( page 110).

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.
The tyre pressure monitor is not able to
warn you of a sudden loss of pressure, e.g.
if the tyre is penetrated by a foreign object.
In the event of a sudden loss of pressure,
bring the vehicle to a halt by braking care-
fully. Do not make any sudden steering
movements when doing so.
i
The operation of the tyre pressure moni-
tor can be affected by interference from
radio transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.
