The « Rent » button is displayed* if there are cars available to rent at the selected station. After tapping this button, you will see the car that has been assigned to you. If there are other cars available to rent at this station, you can select one of them by clicking the « Change » button. Finally, tap on « Confirm » to start your rental.
You still need to tap your badge on the car before and after your trip even if you have remotely started your rental.
*For your first rental, you will need to swipe your card on the charge point. Then enter your PIN code and follow the instructions.
