1993 Volvo 960
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.
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 retailer for correct installation.
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.
Trailer towing does not normally present any particular problems, but take into consideration:
The rear suspension incorporates "Nivomat", an automatic level regulating system to compensate for
load variations. The system operates when the vehicle is in motion. The rear of the vehicle will however
droop if for instance you are carrying a lot of luggage in the trunk or if the vehicle is hitched to a trailer;
but as soon as you start driving, the "Nivomat" system will raise the rear of the vehicle to the most
suitable level.
●
Recommended hitch tongue load is 110 (50 kgs) for trailer weights below 2,650 lbs (1,200 kgs) and
165 lbs (75 kgs) for trailer weights above 2,650 lbs (1,200 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.
●
Increase tire pressure to recommended full-load pressure. See section "Wheels and tires".
●
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.
●
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.
●
The trailer hitch tongue load (110/165 lbs - 50/75 kg) is part of the vehicle's capacity weight. It may
be necessary to reduce the trunk/cargo area load when towing a trailer to ensure that the max.
permissible axle load or gross vehicle weight are not exceeded.
