Unfortunately, we are not yet able to offer you a refueling or recharging function within the app.
If you urgently need fuel for your car, e.g. to get back to the business area, the fuel costs have to be paid privately. After the trip, send the receipts to firstname.lastname@example.org with the booking number, license plate number and bank account details. After successful verification, the fuel costs will be reimbursed by SIXT share.
Important for you to know: Refueling as well as charging is not incentivized with hvv switch by e.g. free minutes or similar.
You can charge the SIXT share cars with the charging card in the car or the chip on your key ring. How exactly this works, you can find out here.
