BMW 7 Series: Automatic Opening

The luggage compartment lid is opened or closed automatically when one of the luggage compartment lid buttons is pressed. A basic prerequisite being that there must be no "inhibit condition" present. You will find a description of the inhibit conditions in the "Luggage compartment lid movement inhibit conditions" section of this Product Information.

Automatic Opening Procedure

The following procedure begins with a closed luggage compartment lid.

  • Luggage compartment lid button with luggage compartment lid symbol pressed briefly

NOTE: On the US variant, the luggage compartment lid button on the identification transmitter must be released otherwise the luggage compartment lid will not be opened automatically.

  • Power supply switched to luggage compartment lid lift and request to unlock the luggage compartment lid issued by the Car Access System
  • The junction box electronics unlock the luggage compartment lid. Initially, the luggage compartment lid lock is actuated.
  • The luggage compartment lid contact switch changes from closed to open.
  • The HKL controls the spindle drives to open the luggage compartment lid.

The luggage compartment lid is completely opened. If one of the inhibit conditions becomes active during luggage compartment lid movement, this will stop further movement of the luggage compartment lid.

Luggage Compartment Lid Opening with Comfort Access

Vehicles equipped with the Comfort Access option also have a "keyless opening" luggage compartment lid function.

The junction box electronics wake a sleeping vehicle in response to the outer luggage compartment lid button being pressed. The junction box electronics send the request on the K-CAN2. The Car Access System with Comfort Access receives the request and arranges for the identification transmitter to register with the vehicle.

Once the identification transmitter has been successfully verified by the Car Access System, the latter arranges for the luggage compartment lid to be unlocked. The junction box electronics execute the unlocking procedure.

As soon as the status of the luggage compartment lid contact switch changes, the junction box electronics issue a notification on the K-CAN2. The central gateway module implements the signal on the K-CAN. In response, the HKL then executes the automatic opening procedure.
