– Reading in the information from the antenna for

system R47:
The switch for access and start authorisation
passes the data, which the vehicle key sends via
remote control, on to the control unit for access
and start authorisation. The control unit
evaluates the data.
– Reading in the signal from the brake light
switch F (only for vehicles with Advanced Key):
To start the vehicle using the button for access
and start authorisation, the brake pedal must be
actuated.
– Exchanging data with the key using the
integrated read coil:
If a key is inserted into the switch for access and
start authorisation (= S contact on), the
electronics system transmits electric power into
the key via the read coil. The key then sends the
key identification into the switch via the
transponder and the read coil. This sends the
information to the control unit for access and
start authorisation.
