Radio remote control
Used to operate:
● central locking system
● anti-theft locking system
● anti-theft alarm system
● power windows
The radio remote control has a range of approx. 20 metres. It can be
restricted by external influences. The
hazard warning flashers confirm
operation.
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Fault
If the central locking system cannot
be operated with the radio remote
control, it may be due to the following:
● The range is exceeded.
● The battery voltage is too low.
● Frequent, repeated operation of the radio remote control while not
in range, which will require re-
synchronisation.
● 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.

The engine oil life system lets you
know when to change the engine oil
and filter. Based on driving
conditions, the interval at which an
engine oil and filter change will be
indicated can vary considerably.
Instruments and controls107In the Uplevel-Combi-Display, the
remaining oil life duration is displayed
in the Vehicle Information Menu .
In the Midlevel-Display, the remaining
engine oil life duration is displayed by
control indicator I, therefore the
