You can change the date or hour (or both) by opening the page with your booking request and clicking the button "Modify". Use the field "Validate" to finalize the change and the owner will be notified by e-mail of your modification.
Please take into account that the owner can reject your modified request if the new time frame appears inconvenient.
We do recommend to pro-actively communicate with the owner through the CarAmigo chat function to prevent last-minute cancellations.
Important: changing the booking request after payment is possible only by canceling the current booking and making new request. Ongoing changes during the carsharing experience are possible only for extending the booking period.
