Breaking-in your vehicle

Your vehicle does not need an extensive break-in. Try not to drive continuously at the same speed for the first 1,000 miles (1,600 km) of new vehicle operation. Vary your speed frequently in order to give the moving parts a chance to break in.
Drive your new vehicle at least 1,000 miles (1,600 km) before towing a trailer. For more detailed information about towing a trailer, refer to Trailer towing in the Tires, Wheels and Loading chapter.
Do not add friction modifier compounds or special break-in oils since these additives may prevent piston ring seating. See Engine oil in the Maintenance and Specifications chapter for more information on oil usage.
