If a complete set of wheels without
sensors is mounted (e.g. four winter
tyres), a message 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

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 repair kits 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 people 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
recalculates. The following relearn
process takes up to 10 minutes of
driving with a minimum speed of
12 mph. In this case
