Radio remote control
synchronisation
To avoid a resynchronisation of the
key, replace the battery as soon as
the range reduces or battery
replacement is indicated by a
message in the Driver Information
Centre.
If the battery is completely
discharged, the key has to be
synchronised after battery
replacement: unlock the door with the
key in the driver's door lock. The radio
remote control will be synchronised
when you switch on the ignition and
then push button c.
Fault
If the central locking system cannot
be operated with the radio remote
control, the cause may be one of the
following:
● Fault in radio remote control
● Range exceeded
● Battery voltage of the key 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
