The labels, new/hot/sold/best price are being turned on by default. You may choose if you want to show them in your website or not. By default; new vehicles are having a label for 5 days. And hot is turned on when there is no vehicle listed as new and more than 5 views by default.
How to turn off the labels?
Go to your RD-Autos Configuration page, and check the right column. Then set "Show labels" to "No"
Changing the labels.
You may choose the count of days to show the new label. As said by default it is 5 days. As you can see in the above image you may set it your self. Also hot vehicles may be changed as 5 is pretty low. Depends on the avarage of the hits.
It will not be shown when you set the Hot vehicle value to 0 (null)
