1987 Volvo 760
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 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 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 ("
" light goes on) on models with automatic transmission.
●
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".
●
Try to keep the fuel tank well filled-this prevents the formation of condensation in the tank.
In addition in extremely cold weather conditions it is worthwhile to add fuel line deicer before refueling.
●
Use the correct grade of engine oil to avoid difficulties when starting. See section "Engine oil".
●
The load placed on the battery is greater during the winter since the heater, windshield wipers,
lighting etc. are used more often. Moreover, the capacity of the battery decreases as the temperature
drops. In very cold weather, a poorly charged battery can freeze and be damaged. It is therefore
advisable to check the state of charge more frequently and spray an anti-rust oil on the battery posts.
●
To prevent the washer reservoir from freezing, add washer solvents containing antifreeze. This is
important since dirt is often splashed on the windshield during winter driving, thus requiring frequent
use of the washers and wipers.
The Volvo washer solvent should be diluted as follows:
