External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced tyre
pressure monitoring system sensors
must be dismounted and serviced. For the screwed sensor: replace
valve core and sealing ring. For
clipped sensor: replace complete
valve stem.
Vehicle loading status Adjust tyre pressure to load condition according to tyre information label or
tyre pressure chart 3 234, and select
the relevant setting in the menu Tire
Load in the Driver Information Centre,
Vehicle Information Menu 3 94.
Select:
■ Light for comfort pressure up to
3 people
■ Eco for Eco pressure up to
3 people
■ Max for full loading
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 dependency
Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
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).
