Trailer towing does not normally present any particular problems, but take into consideration:
Increase tire pressure to recommended load pressure. See section "Wheels and tires".
WARNING! 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 dealer for correct installation.
WARNING! Bumper-attached trailer hitches must not be used on Volvos, nor should safety chains be
attached to the bumper. Trailer hitches attaching to the vehicle rear axle must also not be used.
Recommended hitch tongue load is 140-150 (64-68 kgs) for trailer weights above 2,650 lbs (1,200
kgs) and 110 lbs (50 kgs) for trailer weights below 2,650 lbs (1,200 kgs). However, the hitch tongue
load should not exceed 200 lbs (90 kgs).
For trailer weights between 2,650-3,300 lbs (1,200-1,500 kgs) a top speed of 50 mph (80 km/h)
should never be exceeded.
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 lower gear and turn off air
conditioner if temperature gauge pointer enters the red range.
Disengage the overdrive on models with automatic transmission
Avoid overload and other abusive operation.
Hauling a trailer affects handling, durability, and economy.
It is necessary to balance trailer brakes with the towing vehicle brakes to provide a safe stop. Check
and observe State/Local regulations.
Do not connect the trailer's brake system directly to the vehicle's brake system.
More frequent vehicle maintenance is required.
Remove the ball and drawbar assembly when the hitch is not being used.
NOTE: Refer to section "Automatic transmission" for additional trailer hauling
tips.
