180 Vehicle care
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 must be reduced,
switch off ignition before reducing.
Auto learn function
After changing wheels, the vehicle
must 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
$
can be
displayed or pressure values can
swap in the Driver Information Centre.
If problems occur during the relearn
process a warning message is
displayed in the Driver Information
Centre.
Temperature compensation
Cold tyres decrease the tyre
pressure, warm tyres increase the
tyre pressure. The tyre pressure
monitoring system considers this
effect for the warning messages.
The tyre pressure value displayed in
the Driver Information Centre shows
the actual tyre pressure. Therefore it
is important to check tyre pressure
with cold tyres.
Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than
2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and
rear wheels periodically. Ensure that
the direction of rotation of the wheels
is the same as before.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
