Tyre pressure display
Information on tyre pressures is shown in the
display. After a few minutes of driving, the cur-
rent tyre pressure of each tyre is shown in the
Service menu of the display.
For further information on displaying the current
tyre pressures, refer to "Checking the tyre pres-
sure electronically" (
Y
page 371).
Important safety notes
It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operating conditions
(
Y
page 369).
Note that the correct tyre pressure for the cur-
rent operating conditions must first be program-
med into the tyre pressure monitor. If there is a
substantial loss of pressure, the warning thresh-
old for the warning message is aligned to the
reference values programmed in. Restart the
tyre pressure monitor after adjusting the cold
tyre pressure (
Y
page 372). The current pres-
sures are saved as new reference values. This
will ensure that a warning message will only
appear if the tyre pressure drops significantly.
The tyre pressure monitor does not warn you if a
tyre pressure is incorrect. Observe the notes on
the recommended tyre pressure (
Y
page 369).
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. following
penetration by a foreign object. In this event,
bring the vehicle to a halt by braking carefully.
Avoid sudden steering movements.
The
h
warning lamp on the instrument clus-
ter shows a detected loss in pressure or a mal-
function:
R
if the
h
warning lamp is lit continuously,
the tyre pressure on one or more tyres is sig-
nificantly too low. The tyre pressure monitor
is not malfunctioning.
R
if the
h
warning lamp flashes for around a
minute and then remains lit constantly, the
tyre pressure monitor is malfunctioning.
The display also shows a message (
Y
page 280).
If the tyre pressure monitor is malfunctioning, it
may be more than ten minutes before the
h
warning lamp displays the malfunction. When
the error has been rectified, the
h
warning
lamp goes out after a few minutes of driving.
The tyre pressure values indicated by the on-
board computer may differ from those meas-
ured at a filling station with a pressure gauge.
The tyre pressures shown by the on-board com-
puter refer to those measured at sea level. At
high altitudes, the tyre pressure values indica-
ted by a pressure gauge are higher than those
shown by the on-board computer. In this case,
do not reduce the tyre pressures.
If radio transmitting equipment (e.g. cordless
headphones, two-way radios) is operated inside
the vehicle or in the vicinity of the vehicle, this
can interfere with the operation of the tyre pres-
sure monitor.

The current tyre pressure of each wheel is
shown in the display.
If the vehicle has been parked for longer than
20 minutes, the
Tyre pressures will be
displayed after a few minutes of driv‐
ing
message appears in the display.
After a teach-in period, the tyre pressure moni-
tor automatically detects new wheels or new
sensors. As long as clear allocation of the tyre
pressure values to the wheel positions is not
possible, the Tyre pressure monitor active
message is displayed instead of the tyre pres-
sure display. The tyre pressures are already
being monitored.
