0 Don't tow a trailer at all during the first 500 miles (800 km) your new vehicle is driven. Your engine, axle or other parts could be damaged. Then, during the first500 miles (800 km) that you tow a trailer, don't drive over 50 mph (80 km/h) and don'tmake starts at full throttle. This helps your engine and other parts of your vehicle wear in at the heavier loads. If you have an automatic transmission, you should use DRIVE (D) (or, as you need to, alower gear) when towing a trailer. Operating your vehicle in DRIVE (D) when towing a trailer will minimize heat build-up and extend the life of your transmission.

Just drive in FOURTH (4) gear (or, as you need to, alower gear). 0 0 Three important considerations have to do with weight: Weight of the Trailer How heavy cana trailer safely be?
