In practice there is no "locked" position for the lock on the tailgate/trunk lid. The difference between locked and unlocked is whether the central electronic module (CEM) will activate the lock motor or not when the switch on the tailgate/trunk lid is pressed.

The tailgate is "locked" and "unlocked" at the same time as the other doors if an unlock command is received from the remote key. The tailgate can also be unlocked separately with a special button on the remote key or via switch on Light switch module (LSM). There is also a function for activating the lock motor via the remote key or switch on Light switch module (LSM).

The switch on the tailgate/trunk lid and the lock motor (6/8) are directly connected to Central electronic module (CEM) and Power Operated Tailgate Module (POT) (optional equipment).
