Then, during the first 500 miles (800 km) that you tow a trailer, don't drive over50 mph (80 km/h) and don't make starts at full throttle. This helps your engine and other parts of your vehicle wear in at the heavier loads. You should use DRIVE (D) (or, as you need to, a lower gear) when towing a trailer.
