Battery life problem, error message, red terminal LED *You discover that the battery life is insufficient before taking the vehicle* Call technical support to cancel the reservation and then book at another location. *On iOS I can't find the start button anymore* This is because you clicked "lock" twice by mistake. You must log in to https://clem.mobi, go to your reservations/current reservation/details. Then press "Start". *Error message "We are unable to communicate with the vehicle"* Check that the green LED is on on the small driver's door window (if it's red it's a reflection), if it's not on, press once and release, wait 60 seconds (even if it's green after a few seconds) then try to open the vehicle using the app. *The same error message continues to appear, there is no 4G network* Turn off the mobile data (4G) on your smartphone, flash the QR code next to the green fingerprint (to connect directly to the vehicle) and enter your reservation code (see your SMS) on the screen that appears on your smartphone. This operation will also allow you to close the vehicle. *The LED is on and the application does not lock/unlock the vehicle after 60 seconds* Check that the vehicle is off, the gearbox in P and close all the doors firmly and try again. You pressed the green fingerprint but the LED does not light up green, the vehicle has broken down, call assistance to cancel your reservation. *On return, the vehicle does not charge* If the LEDs on the vehicle dashboard flash, it is ok (charging will start later). Otherwise, check the connection on the terminal and vehicle side, if the dashboard LED still does not flash, call technical support to block the station).
