To use the keyless function, you just need to carry your key with you. As long as the key is within your car's detection range and it has a sufficient battery level, you can lock and unlock the car by interacting with the different touch-sensitive areas on the door handles.
Important
Keyless locking
When carrying your key, you can lock the car by touching the small indentation on the outer part of the door handle.
To lock the boot hatch without using a key, you can use the locking button on the lower edge of the hatch. If you press this button, the car will lock once the boot is closed.
It's also possible to lock the doors while the boot hatch is still open. Once you've locked the rest of the car using the door handle, the boot hatch will lock too once it's closed.
Note
Tip
Closing the windows with keyless locking
You can close all of the side windows and the panoramic roof at the same time by holding a finger against the indentation on the outside of the door handle.
Keyless unlocking
With keyless unlocking, your car unlocks automatically when you pull the door handle while carrying your key.
There is also a rubberised button under the boot hatch's handle which you can press to unlock the car.
