The recommended tyre pressures can be
found in the table on the fuel filler flap.
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.

General notes
If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you if the
pressure drops in one or more of the tyres.
The tyre pressure monitor only functions if
the corresponding sensors are fitted to all
wheels.
Information on tyre pressures is shown in the
multifunction display. After a few minutes of
driving, the current tyre pressure of each tyre
is shown in the

tion display.

Important safety notes
It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operating situation
(
page 600). Note that the correct tyre pres-
Y
sure for the current operating situation must
first be taught-in to the tyre pressure monitor.
If there is a substantial loss of pressure, the
warning threshold for the warning message is
aligned to the reference values taught-in.
Restart the tyre pressure monitor after
adjusting to the cold tyre pressure
(
page 604). The current pressures are
Y
saved as new reference values. This will
ensure that a warning message will only
appear if the tyre pressure drops significantly.
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. Observe
menu of the multifunc-
page 603).
