If you picked up your vehicle through the agency counter at departure, you will be able to return your vehicle to the agency's garage. 

If your rental is compatible with self-service access, you can end your rental without having to go back to the counter via the mobile application. 

On the "Vehicle" tab, simply press the "Finish my rental" button and follow the few check steps.  

The application directly confirms that the vehicle is locked, you can leave with complete peace of mind!
