Driving with a Trailer

There are a number of things to consider when towing a trailer, such as the towbar, the trailer and how the load is distributed in the trailer.

The load-carrying capacity is determined by the vehicle's curb weight. The total weight of all passengers and any installed accessories, e.g. towbar, reduces the vehicle's load-carrying capacity by the corresponding amount.

• Towbars fitted to the vehicle must be approved for the intended use.
• Distribute the load on the trailer so that the weight on the towbar complies with the specified maximum towball weight. The tongue weight is calculated as part of the vehicle's payload.
• Increase the tire pressure to the recommended pressure for full load.
• The engine is subjected to a greater load than usual when towing a trailer.
• Towing a trailer affects the vehicle's handling, durability and driving economy.
• Do not tow a heavy trailer when the vehicle is new. Wait until the mileage has reached at least 1000 km (620 miles).
• On long and steep downgrades, the vehicle's brakes are subjected to much more load than usual. When shifting manually, adapt the speed accordingly.
• Follow applicable regulations regarding permitted speed and weight.
• Drive slowly when towing a trailer on long and steep grades.
• The maximum trailer weights given only apply to altitudes up to 1000 meters (3280 feet) above sea level. At higher altitudes, engine power (and thus the vehicle's climbing ability) is decreased due to the reduced air density, and the maximum trailer weight must therefore be reduced. The weight of the vehicle and trailer must be decreased by 10% for each additional 1000 m (3280 feet) or part thereof.
• Avoid driving with a trailer on grades steeper than 12%.
• Avoid overloading and other improper use.
• The trailer's brakes must be balanced with the vehicle's brakes to help ensure safe stops (follow applicable local regulations).

• Bumper-attached trailer hitches must not be used on Volvos, nor should safety chains be attached to the bumper.
• Do not use trailer hitches attached to the rear axle of the vehicle.
• Never connect a trailer's hydraulic brake system directly to the vehicle brake system, nor a trailer's lighting system directly to the vehicle lighting system. Consult your nearest authorized Volvo retailer for correct installation.
• When towing a trailer, the trailer's safety chains or wire must be correctly fastened to the attachment points provided in the trailer hitch on the vehicle. The safety chain or wire must never be fastened to or wound around the towing ball.

NOTE

Extreme weather conditions, towing a trailer, high altitude and lower fuel grade than recommended are factors that can significantly increase the vehicle's fuel consumption.

Trailer weight

Self-leveling suspension*

The vehicle's self-leveling system attempts to keep the vehicle at a constant level, regardless of load (up to the maximum permitted weight). When the vehicle is stationary, the rear end of the vehicle will be slightly lowered, which is normal.

Driving in hilly terrain or hot weather

Under certain conditions there is a risk of overheating when driving with a trailer. If overheating of the engine and drive system is detected, a warning symbol will illuminate in the instrument panel and a message will appear.

The automatic transmission adapts the gear selection to the current load and engine speed.

Steep grades

Do not lock the automatic transmission into a higher gear than what the engine can handle ‒ it is not always preferable to drive in high gears at low rpm.
