If the vehicle was parked for longer than
20 minutes, the Tyre pressures will be Tyre pressures will be
displayed after displayed after a a few
ing ing message is shown.
After a teach-in period, the tyre pressure moni-
tor automatically detects new wheels or new
sensors. As long as a clear allocation of the tyre
pressure values to the individual wheels is not
possible, the Tyre Tyre pressure pressure monitor
message is shown instead of the tyre pressure
display. The tyre pressures are already being
monitored.
After an emergency spare wheel has been fitted,
the system may still display the tyre pressure of
the removed wheel for a few minutes. 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 Please correct tyre pressure Please correct tyre pressure
R
message appears in the multifunction display,
the tyre pressure in at least one tyre is too
low. The tyre pressure must be corrected
when the opportunity arises.
If the Tyre Tyre pressure pressure Check
R
sage appears in the multifunction display, the
tyre pressure in one or more tyres has drop-
ped significantly. The tyres must be checked.
If the Tyre pressure Caution Tyre mal‐ Tyre pressure Caution Tyre mal‐
R
function function message appears in the multifunc-
tion display, the tyre pressure in one or more
tyres has dropped suddenly. The tyres must
be checked.
Observe the instructions and safety notes in the
display messages in the "Tyres" section
( page 256).

If the position of the wheels on the vehicle is
changed, 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 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
X
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 ( page 337).
