Tailgate/tailgate lock
The tailgate lock is equipped with the familiar rotary striker and interlock pawl closing elements. The tailgate lock can be unlocked mechanically or electrically and then opened.
If the vehicle is equipped with an Automatic Soft Close system motor for the tailgate, the tailgate only needs to be pressed down lightly into the tailgate lock to close it. This starts the electric motor and the tailgate closes fully.
If the vehicle is equipped with an alarm system (DWA), an alarm is triggered when the tailgate lock is mechanically unlocked using the integrated key (integrated in the infrared remote key or in the ID sensor). Precondition: Vehicle locked and secured via the central locking system.
The tailgate lock can also be electrically unlocked via the operating points (e.g. ID sensor, outside tailgate button) and then opened.
The lock barrel is mechanically connected with the tailgate lock via a Bowden cable. If the integrated key is inserted into the lock barrel and then turned, the tailgate lock is mechanically unlocked and the tailgate opens automatically or electrically by spring force.
The tailgate lock is electrically unlocked via the operating points. The Body Domain Controller (BDC) activates the direct current motor of the release drive in the tailgate lock, thereby triggering the tailgate lock to unlock.
When the tailgate opens, the luggage compartment lights are switched on by the rotary striker switch. The change in status of the rotary striker switch is also evaluated for the alarm system (DWA).
The locking pawl switch indicates to the electronics in the electric motor for the Automatic Soft Close system of the tailgate whether or not the interlock pawl has fallen into the rotary striker (pre-locked or locked).
To lock, the tailgate must be pressed into the tailgate lock. When the locking pawl switch is operated by the boot lid/tailgate being pressed lightly into the boot/tailgate lock (boot/tailgate in the semi-engaged position), this starts the electric motor for the boot/tailgate Automatic Soft Close system.
The electronics of the electric motor for the Automatic Soft Close system of the tailgate evaluate the signal of the locking pawl switch as the start signal. The electric motor moves the rotary striker via the Bowden cable until the rotary striker switch signals a status change. The electric motor is stopped.
