played for the position where the spare wheel is
fitted is not the same as the current tyre pres-

Warning messages of the tyre pressure
monitor
If the tyre pressure monitor detects a pressure
loss in one or more tyres, a warning message is
shown in the multifunction display. The yellow
tyre pressure warning lamp then lights up:

If the position of the wheels are interchanged on
the vehicle, the tyre pressures may be displayed
in the wrong positions for a short time. After a
few minutes of driving, this is rectified and the
tyre pressures are displayed in the correct posi-
tions.
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 cur-
rently set tyre pressures as the reference values
for monitoring. In most cases, the tyre pressure
monitor will automatically detect the new refer-
ence values after you have changed the tyre
pressure. However, you can also set reference
values manually as described here. The tyre
pressure monitor then monitors the new tyre
pressure values.
