following:
■ Fault in radio remote control.
■ 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.
Manual unlocking 3 23.Electronic key system
Enables a keyless operation of the
following functions:
■ central locking system 3 23

started, the cause may be one of the
following:
■ Fault in electronic key.
■ Electronic key is out of reception range.
■ The battery voltage is too low.
■ 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.
To rectify the cause of the fault,
