G11311447

The IAU (ImmobiIizer Antenna Unit) is used if the KVM is unable to authorize the smart key. If the KVM is unable to identify the smart key, for example if the smart key battery voltage is low or there is local RF interference, the transponder within the smart key can be read in the conventional manner. The driver will be alerted to this by a chime and a message in the IC (Instrument Cluster) message center 'SMART KEY NOT RECOGNISED, REPOSITION OR PLACE AS SHOWN AND PRESS START BUTTON'.
