Adding Equipment to the Outside of the Vehicle

Things added to the outside of the vehicle can affect the airflow around it. This can cause wind noise and can affect fuel economy and windshield washer performance.

Check with your dealer/retailer before adding equipment to the outside of the vehicle.
