You don't really need to use a trip odometer, the mileage display in the center console display resets itself to 0 every time you fill up.

What you DO need to do, is hit the reset button to reset the average mileage to 0. so that you get an accurate mileage reading for THAT tank full of gas. The "miles driven" resets to 0 when you fill up. but the average MPG reading holds over from fill-up to fill-up until you reset it manually. Lets you get average mileage reading for longer trips with multiple tanks of gas.
