Removing

• The alignment and exact position of the antennas are crucial for their function. Before removing antennas in the passenger compartment, mark the exact position and alignment of antennas and secure them in exactly these positions and alignments when installing. The thickness of the adhesive pad layer on antennas is an integral part of their function. If the bond of one antenna loosens, do not reapply standard adhesive on it. 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 off the ignition and all electrical consumers and move the ignition key or start button into the 0 position (preliminary engaged position).

- Remove the center console.
