The Car Pass contains security
related vehicle data and should
therefore be kept in a safe place.
When the vehicle is taken to a
workshop, this vehicle data is needed
in order to perform certain operations.
Radio remote control
Used to operate: ● Central locking system
● Anti-theft locking system
● Anti-theft alarm system
The radio remote control has a range of approx. 6 metres. This range can
be affected 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:
● Range exceeded.
● Battery voltage too low.
● Frequent, repeated operation of the radio remote control while not
in range, which will require
reprogramming. Seek the
assistance of 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.
