Tyre pressure monitoring system
▌ Function of the tyre pressure monitoring system
The system checks the tyre pressure and the tyre
temperature of the tyres fitted to the vehicle by
means of a tyre pressure sensor.
New tyre pressure sensors, e.g. in winter tyres, are
automatically taught-in during the first journey they
are used.
It is the driver's responsibility to set the tyre pres-
sure to the recommended cold tyre pressure suita-
ble for the operating situation ( / page 236).
Note that the correct tyre pressure for the current
operating situation must first be taught-in to the
tyre pressure monitoring system. If a substantial
loss of pressure occurs, the warning threshold for
the warning message is aligned to the taught-in
reference values. Restart the tyre pressure monitor
after adjusting to the cold tyre pressure
( / page 239). The current pressures are saved as
new reference values. This will ensure that a warn-
ing message will only appear if the tyre pressure
drops significantly.
The
h
warning lamp in the instrument cluster
displays a detected pressure loss or a malfunction
as follows:
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.
R
a message also appears in the instrument clus-
ter.
System limits
The system may be impaired or may not function in
the following situations:
R
the tyre pressure has been set incorrectly.
R
there is a sudden pressure loss caused, for
example, by a foreign object penetrating the
tyre.
R
there is a malfunction caused by another radio
signal source.
If the tyre pressure monitor is malfunctioning, it
may take more than ten minutes for the
h
tyre
pressure warning lamp to inform you of the mal-
function. When the fault has been rectified, the
h
warning lamp goes out after you have driven
for a few minutes.
The tyre pressure values indicated by the on-board
computer may differ from those measured at a fill-
ing station using 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 indicated by a
pressure gauge are higher than those shown by the
on-board computer. In this case, do not reduce the
tyre pressures.
▌ Checking the tyre pressure electronically
Requirements:
R
The vehicle is switched on.
