2005 Volvo S80
●
Maximum speed when towing a trailer: 50 mph (80 km/h).
●
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 a lower gear and turn off the air
conditioner if the temperature gauge pointer enters the red range.
●
If the automatic transmission begins to overheat, a message will be displayed in the text window.
●
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.
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.
●
When towing a trailer, the trailer's safety wire must be correctly fastened to the hole or hook
provided in the trailer hitch on the car. The safety wire should never be fastened to or wound around
the drawbar ball.
NOTE:
●
When parking the car with a trailer on a hill, apply the parking brake before putting the gear selector
in (P)ark. When starting on a hill, put the gear selector in (D)rive before releasing the parking brake.
●
If you use the manual (Geartronic) shift positions while towing a trailer, make sure the gear you select
does not put too much strain on the engine (using too high a gear).
●
The drawbar assembly/trailer hitch may be rated for trailers heavier than the car is designed to tow.
Please adhere to Volvo's recommended trailer weights.
* When driving for prolonged periods at temperatures above 86° F (30° C), the maximum recommended
weight is 2000 lbs (900 kg).
