Opening the trunk hands-free
If your hands are full and you have your distance-capable key with you, you can open or close the trunk by passing your foot under the rear bumper.
If your vehicle is locked, using the hands-free feature will unlock and open the trunk. You can choose whether only the trunk or all of the doors unlock via the locking settings in the center display.

Make sure you have a charged distance-capable key on you.
- Make a single kicking motion under the rear bumper and move back.A short audible response indicates that it's about to open.Repeated foot movements cancel or reset the activation.
Note
Closing the trunk hands-free
You can also use the kicking motion to close the trunk hands-free. When the hatch is about to close, you will hear a beeping sound. The hatch will start moving shortly after.
If the function appears to be unresponsive, keep in mind that obstructions to the sensor such as mud can interfere with a proper response.
