After a teach-in period, the tyre pressure moni-

sensors. As long as a clear allocation of the tyre
pressure values to the individual wheels is not
possible, the

If an emergency spare wheel is fitted, for a
few minutes the system may continue to
show the tyre pressure of the wheel that has
been removed. If this occurs, note that the
value displayed for the position where the
spare wheel is fitted is not the same as the
current tyre pressure of the emergency spare
wheel.
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 wheel positions on the vehicle are inter-

for the wrong positions for a short time. After a
few minutes of driving, this is rectified 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 cur-
rently set tyre pressures as the reference values
for monitoring. In most cases, the tyre pressure
monitor will automatically detect the new refer-
driv‐
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.
