Closing rear lid
WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
The lock of the luggage-compartment lid closes mechanically. If the status 'trunk lid/tailgate locked' is detected by the power module, the Comfort Access control module starts a search for the identifier via the luggage compartment antenna. If an identifier in the luggage compartment replies, the CAS control module transmits the command to open the trunk lid/tailgate to the power module. The boot lid/tailgate lift opens the boot lid/tailgate. If another valid identifier is located in the transmission range of the vehicle aerials, the luggage compartment remains closed. The identifier locked in the luggage compartment is disabled for the next opening of the vehicle.
