This article is a step-by-step breakdown on how to set up vehicles to a loaner vehicle. This will only be available for the system and not on your website. A loan vehicle would mean that the rack rate of a vehicle class is zero.
Step 1
Firstly, navigate to Settings → Car Rental → Settings tab, and here find the option Enable Loan Vehicle Rental and set it to Yes.
Next, click on the blue Save button located at the bottom of the page.
Step 2
Now when you are doing a reservation, on Step 3, there will be a white Loan Vehicle button as shown in the picture below highlighted in red.
When you click on this button, you will see that the rack rate is now zero for the vehicle class that you have selected. An example is shown in the picture below.
To set the reservation back to a regular reservation, navigate back to Step 3, and select the Regular Reservation button as shown in the picture below highlighted in red.
