The trailer load should be positioned so that it does not shift and the tongue load should be 10% of the trailer's weight. However, the tongue load should not exceed the maximum permissible weights indicated in the table above. When towing trailers without brakes, the maximum permissible trailer weight is 1,700 lbs (750 kg). If necessary, redistribute the weight of any cargo in the trailer to avoid excessive weight on the trailer hitch. The maximum trailer weight listed in the table for All Wheel Drive models, 5,000 lbs (2250 kg) is only applicable when there are not more than two occupants in the vehicle, in the front seats, with a combined weight of 300 lbs (135 kg), with no other cargo in the vehicle. The maximum weight listed for Front Wheel Drive models, 4,000 lbs (1800 kg) is only applicable when there are not more than four occupants in the vehicle, in the front seats and second row of seats, with a combined weight of • Vehicles used for towing a trailer on a regular basis, or for long-distance highway towing should be equipped with an automatic transmission oil cooler and Volvo's automatic self-leveling system for the rear suspension. Consult your Volvo retailer. Volvo recommends the use of Volvo trailer hitches that are specially designed for the vehicle. All Volvo models are equipped with energy-absorbing shock-mounted bumpers. Trailer hitch installation should not interfere with the proper operation of this bumper system. Increase tire pressure to recommended full inflation pressure. See chapter "Wheels and tires." When your vehicle is new, avoid towing heavy trailers during the first 620 miles (1,000 km). Engine and transmission are subject to increased loads. Therefore, engine coolant temperature should be closely watched when driving in hot climates or hilly terrain. Use a lower gear and turn off the air conditioner if the temperature gauge needle enters the red range. • • • • • 06 • • • • 152
