68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE • Check the coolant and oil levels frequently. • Vary throttle position at highway speeds when carrying or towing significant weight. Because of the construction of the Cummins Diesel engine, engine run-in is enhanced by loaded operating conditions which allow the engine parts to achieve final finish and fit during the first 6,000 miles (10 000 km). SAFETY TIPS Transporting Passengers This vehicle is designed to carry passengers in the cab only. For safety reasons, NEVER TRANSPORT PASSENGERS IN THE CARGO AREA. WARNING! It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas are more likely to be seriously injured or killed. Do not allow people to ride in any area of your vehicle that is not equipped with seats and seat belts. Be sure everyone in your vehicle is in a seat and using a seat belt properly. CAUTION! • During the first 500 miles (805 km) your new vehicle is driven, do not tow a trailer. Doing so may damage your vehicle. • Limit your speed to 50 mph (80 km/h) during the first 500 miles (805 km) of towing.
