Antennas for Comfort Access
Six antennas are installed for the comfort access system. Three antennas are located in
the exterior and three in the interior.
The antennas for the exterior and interior are inductive antennas and have a ferrite core
which contributes to their compact size. This is of particular advantage for accommodat-
ing the antennas in the outer door handles.
The transmit frequency of the antennas is 125 kHz. All messages that are sent via the
antennas are encrypted.
