Car Pass 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
Depending on model, the vehicle may use a 2-button or 3-button remote
control.
The remote control has a range of
approx. five metres. It can be affected
by external influences. The hazard
warning flashers confirm operation.
Handle with care, protect it from
moisture and high temperatures and
avoid unnecessary operation.
Fault
If the central locking system cannot be operated with the remote control,
it may be due to the following:
● The range is exceeded.
● The battery voltage is too low.
● Frequent, repeated operation of the remote control while not in
range, which will require
reprogramming by 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.
