If there is a substantial pressure loss or if the
tire temperature is excessive, you will be warned
with display messages (
/
page 524) or the
h warning lamp in the instrument cluster
(
/
page 546).
The tire pressure monitoring system is only an
aid. It is the driver's responsibility to set the tire
pressure to the recommended cold tire pressure
suitable for the operating situation.
In most cases, the tire pressure monitoring sys‐
tem will automatically update the new reference
values after you have changed the tire pressure.
You can, however, also update the reference val‐
ues by restarting the tire pressure monitoring
system manually (
/
page 364).
System limits
The system may be impaired or may not function
particularly in the following situations:

One of the following displays appears:
R
Current tire pressure of each wheel:
R
Tire pressure displayed after driving for a
few minutes.
R
Tire Pressure Monitor Active : the teach-in
process of the system is not yet complete.
The tire pressures are already being moni‐
tored.
#
Compare the tire pressure with the recom‐
mended tire pressure for the current operat‐
ing condition (
/
page 361). Observe the
notes on tire temperature (
/
page 360).
% The values displayed in the driver display
may deviate from those of the tire pressure
gauge as they refer to sea level. At high ele‐
vations, the tire pressure values indicated by
a pressure gauge are higher than those
shown by the driver display. In this case, do
not reduce the tire pressure.
