1997 Volvo 850
Trailer towing does not normally present any particular problems, but take into consideration:
●
Increase tire pressure to recommended full. See section "Wheels and tires".
●
Recommended hitch tongue load is 110 (50 kg) for trailer weights below 2,650 lbs (1,200 kg) and 165
lbs (75 kg) for trailer weights above 2,650 lbs (1,200 kg). For trailer weights between 2,650 - 3,300 lbs
(1,200 - 1,500 kg) 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 the temperature gauge pointer enters the red range.
●
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,
●
Volvo recommends the use of synthetic engine oil when towing a trailer over long distances or in
mountainous areas.
NOTE: Refer to section "Automatic transmission" for additional trailer hauling tips.
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 not be used.
●
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.

Cold weather precautions
If you wish to check your car before the approach of cold weather, the following advice is worth noting:
●
Make sure that the engine coolant contains at least 50 percent antifreeze: that is, 3.7 qts. (3.5 liters)
Volvo Genuine Coolant/Antifreeze. This gives protection against freezing down to -31°F (-35°C). See
