Fault
If the central locking system cannot
be operated with the remote control,
it may be due to the following:
■ Range exceeded
■ Battery voltage too low
■ Frequent, repeated operation of the
remote control while not in range,
which will require reprogramming
by a workshop■ Overload of the central locking system by operating at frequent
intervals, the power supply is
interrupted for a short time
■ Interference from higher-power radio waves from other sources

Relearn function
After changing wheels, the system
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, a warning message is
displayed in the Driver Information
Centre.

Vehicle messages 3 87.
General information The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
Tyre repair kit 3 154.
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 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).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. Ensure that the direction
of rotation of the wheels is the same
as before.
