Locking separately
The trunk lid can be locked separately with the switch in the front passenger glove compartment.

▷ Trunk lid secured, arrow 1.
▷ Trunk lid not secured, arrow 2.
Slide the switch into the arrow 1 position. This secures the trunk lid and disconnects it from the central locking system.
When the front passenger glove compartment is locked, the tailgate cannot be accessed.
This is beneficial when the vehicle is parked using valet service. The infrared remote control can be handed out without the key.
