Make sure you have your key with you.
Opening the boot
Make a single kicking motion under the rear bumper and move back.
A short sound response indicates that the boot is about to open.
Note
Repeated foot movements cancel or reset the activation.
Closing the boot
When you want to use the hands-free feature for closing the boot, repeat the kicking motion once. A short sound response indicates that it's about to close.
If the function appears to be unresponsive, keep in mind that any obstructions to the sensor, such as mud, may interfere with it responding properly.
