The rear compartment lid can be opened by operating the rear compartment lid release switch, located on the instrument panel, or by using the keyless entry transmitter. Battery voltage is supplied to the bed release relay through the bed release fuse. The roof/door module receives the rear compartment lid release request via the rear compartment lid release switch signal circuit. The roof/door module grounds the rear compartment lid release relay control circuit when a release is requested. Grounding the coil causes the bed release relay to energize, providing power to the rear compartment lid release switch, opening the lid.

As an alternate method of operating the rear compartment, an emergency release handle is accessible from within the rear compartment. When the handle is slightly pulled, it will provide a ground for the bed cover release relay which will cause the actuator to operate and open the rear compartment lid. If the handle is pulled further, it will mechanically open the lid, so even if the battery is discharged or there is an electrical concern, the emergency release handle will mechanically open the lid.

The information processing center (IPC) will display the Bed Cover Ajar message in the driver information center if the RDM detects that the rear compartment lid is not completely closed. The IPC receives a serial data message from the roof/door module requesting that the Bed Cover Ajar message be displayed. The RDM receives an input from the rear compartment ajar switch through the rear compartment lid ajar switch signal circuit.
