Tyre pressure monitor warning mes-
sages
If the tyre pressure monitor detects a signifi-
cant pressure loss on one or more tyres, a
warning message is shown in the multifunc-
tion display. A warning tone also sounds and
the tyre pressure warning lamp lights up in
the instrument cluster.
Each tyre that is affected by a significant loss
of pressure is highlighted in colour.
If the following message appears in the mul-
tifunction display: Please correct tyre
pressure:
Check the tyre pressure on all four wheels

and correct it if necessary.

If the wheel positions on the vehicle are
interchanged, the tyre pressures may be
displayed for the wrong positions for a
short time. This is rectified after a few
minutes of driving, and the tyre pressures
are displayed for the correct positions.
Restarting the tyre pressure monitor
When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the speci-
fied values for monitoring.
In most cases, the tyre pressure monitor will
automatically detect the new reference val-
ues, e.g. if you have:
changed the tyre pressure
R
changed the wheels or tyres
R
fitted new wheels or tyres

If you wish to define the new reference values
manually:
Use the table on the inside of the fuel filler

flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operating conditions.
