R
Tyre pressure monitor active : the teach-in
process of the system is not yet complete. The
tyre pressures are already being monitored.
#
Compare the tyre pressure with the recom-
mended tyre pressure for the current operat-
ing condition (
/
page 376). Additionally,
observe the notes on cold tyres
(
/
page 375).
%
The values displayed in the on-board com-
puter may deviate from those of the tyre pres-
sure gauge as they refer to sea level. At high
elevations, the tyre pressure values indicated
by a pressure gauge are higher than those
shown by the on-board computer. In this case,
do not reduce the tyre pressure.

The recommended tyre pressure is correctly
set for the respective operating status on all of
the wheels (

Restart the tyre pressure monitoring system in the
following situations:

The Tyre press. monitor restarted message is
shown in the Instrument Display.
Current warning messages are deleted and
the yellow h warning lamp goes out.
A er you have been driving for a few minutes,
the system checks whether the current tyre
pressures are within the speci ed range. The
current tyre pressures are then accepted as
reference values and monitored.

driver by means of display messages when there
is a severe tyre pressure loss.

The system may be impaired or may not function
particularly in the following situations:
R
incorrect reference values were taught in
R
sudden pressure loss caused by a foreign
object penetrating the tyre, for example
R
an even pressure loss on more than one tyre
occurs
The system has a restricted or delayed function
particularly in the following situations:
R
poor ground conditions, e.g. snow or gravel
R
driving with snow chains
R
when adopting a very sporty driving style with
high cornering speeds or sudden acceleration
R
driving with a very heavy or large trailer
R
driving with a high load
