Winter Driving; Cold Weather Precautions - Volvo 740 GL Owner's Manual

1985 Volvo 740 GL, GLE, Turbo
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.
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.
NOTE: 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.
Trailer towing does not normally present any particular problems, but take into consideration:
Recommended hitch tongue load is 110 lbs (50 kgs) for trailer weights below 2,650 lbs (1,200 kgs)
and 143-154 lbs (65-70 kgs) for trailer weights above 2,650 lbs (1,200 kgs).
However, the hitch tongue load should not exceed 200 lbs (90 kgs).
For trailer weights of 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 ("
Avoid overload and other abusive operation.
Hauling a trailer affects handling, durability and economy. A trailer air dam (Volvo accessory) will
often improve mileage.
It is necessary to balance trailer brakes with the towing vehicle brakes to provide a safe stop (check
and observe State/Local regulations).
More frequent vehicle maintenance is required.
Remove the ball and drawbar assembly when the hitch is not being used.
Note: Refer to section entitled "Automatic transmission" for additional trailer hauling tips.

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, 5.0 qts. (4.25 liters)
Volvo type C blue-green glycol additive. This gives protection against freezing down to -31°F(-35°C).
See section "Coolant".
