154 Vehicle care
Turn the adjuster wheel to select the
tyre pressure monitoring system.
System status and small pressure
differences are displayed by
a warning message with the
according tyre flashing or by
a warning code in the Driver
Information Center.
Furthermore considerable pressure
differences between the tyres of one
axle or a considerable increased tyre
pressure are displayed by a warning
message or by a warning code in the
Driver Information Center.
Major pressure differences are
indicated additionally by the control
indicator w.
Control indicator w 3 76.
Vehicle messages 3 80.
If the tyre pressure shall be reduced
or increased, switch off ignition.
If a complete set of wheels without
sensors is mounted (e.g. four winter
tyres), a message or a code is
displayed in the Driver Information
Center. The tyre pressure monitoring
system is not operational. Retrofitting
of sensors is possible.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these wheels. Control indicator w
illuminates. For the further three
wheels the system remains
operational.
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory
approved systems can be used.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
The tyre pressure monitoring system
valve cores and sealing rings must be
replaced each time the tyres are
changed.
Adaptive threshold function
The tyre pressure monitoring system
automatically detects if the vehicle is
driven with a tyre pressure
appropriate for a load of up to
3 persons or for a full load.
If the tyre pressure shall be reduced,
switch off ignition before reducing.
Auto learn function
After changing wheels the vehicle has
to be stationary for approx. 20
minutes, before the system gets into
modus of repositioning. The following
relearn process takes up to 10
minutes of driving with a speed of
minimum 20 km/h (12 mph). In this
case $ can be displayed or pressure
values can swap in the Driver
Information Center.
