      No. The carsharing system relies on users returning their cars on time. You can extend your booking (using the app or by calling the Flex-Servicecenter on (+352) 2883 3882), but only if your car hasn’t been booked by another user. Fair play charges will apply if you return the car late.

    • I pressed the start/stop button to switch off the engine while on the road (e.g. in heavy traffic or at a level crossing). The engine won’t start again.

      Don’t worry, this is completely normal. For security reasons, the immobiliser is activated once the engine has been off for five minutes. Simply scan your Flex card against the reader to switch the engine back on again. You don’t even have to get out of the vehicle. The reader will recognise your card if you scan it from inside.
