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.

evaporating off the exhaust system. Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and
engine oil consumption may be
higher.
Additionally, the cleaning process of
the exhaust filter may take place more
often.
