Volvo 1991 240 Model
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.
Trailer hauling 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, it must 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 climate or hilly terrain. Use lower gear and turn off air
conditioner if 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 regulations).
More frequent vehicle maintenance is required.
Remove the ball and drawbar assembly when the hitch is not being used.
Increase tire pressure to recommended full-load pressure. See section "Wheels and Tires."
Note: Refer to section entitled "Automatic transmission" for additional trailer hauling
tips.
Warning: Do not drive with trunk lid or tailgate
open!
Poisonous exhaust gases may enter via the open trunk lid or tailgate. (This is especially true for wagon
models.)
If the trunk lid or tailgate for any reason must be open, proceed as follows:
Close the windows.
Set the heating system controls for floor and defroster to max. and the blower to full speed (4). See
section titled "Heating and Ventilation".
