How to modify a car rental

To modify an existing car rental, please cancel your current reservation and create a new one. 

1. Navigate to the Trips tab in your Engine account.
2. Select the reservation you want to cancel.
3. Click on the Manage trip button on the right-hand side of your screen, then click Cancel car rental.
4. Depending on the policy and the number of days before pick-up, you might be charged a cancellation fee, or a refund might not be available. From there, you can either confirm the cancellation or exit the cancellation window.
