Removing:

• The alignment and exact position of the antennas are crucial for their function. Before removing antennas in interior, mark their exact location and alignment and secure them in this exact position and alignment during installation. The thickness of the adhesive pad layer on antennas is an integral part of their function. If an antenna's bond loosens, re-adhere it with commercially-available adhesive. In this case, a new antenna must be installed with a new adhesive pad. If this is not done, the KESSY system will malfunction.

- Switch ignition and all electrical consumers off and disengage the key or ignition switch in position 0 (ignition off).

- Remove rear seats.

- Remove rear entry trim strips far enough so that vehicle carpet can be folded forward enough to gain access to Interior Access/Start Authorization Antenna 2.
