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.Relearn function
After changing the wheels, TPMS
needs to recalculate.
With the vehicle stationary, select the tyre pressure menu in the Driver
Information Centre by pressing button
on end of wiper lever. Press and hold button for approx. 3 seconds to
initialise recalculation. A
corresponding message appears in
the Driver Information Centre.
Several minutes of driving may be
required to complete the relearn
process.
If problems occur during the relearn
process, control indicator w remains
illuminated and a warning message is displayed in the Driver Information
Centre.

General information
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved tyre repair kits can be used.
Tyre repair kit 3 161.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced,
TPMS sensors must be dismounted
and serviced by a workshop.
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).
