If the vehicle was parked for longer than
20 minutes, the following message appears:

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

message is shown instead of the tyre pressure
display. The tyre pressures are already being
monitored.
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 dis-
played for the position where the spare wheel is
fitted is not the same as the current tyre pres-
sure 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.

when the opportunity arises.

Observe the instructions and safety notes in the
display messages in the "Tyres" section
(
Y
page 277).
If the wheel positions on the vehicle are inter-
changed, the tyre pressures may be displayed
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-
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.

Use the table on the inside of the fuel filler flap
to ensure that the tyre pressure is set cor-
rectly in all four tyres for the current operating
conditions.
Also observe the notes in the section on tyre
pressures (
