If you have your hands full, such as when carrying bags, it can be useful to have the boot open automatically.
If the car is locked, using the hands-free boot unlocking will unlock all doors or only the boot. This is enabled via door locking settings in the centre display.
Make sure you have a charged distance-capable key on you.
Note
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 you try using the hands-free feature without a distance-capable key, three beeps will indicate that the boot cannot 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.
