Driving with a trailer
When towing a trailer, always observe the legal
requirements of the state/province.
•
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 par-
ticular problems, but take into consideration:
•
Increase tire pressure to recommended full
pressure.
•
When your vehicle is new, avoid towing heavy
trailers during the first 620 miles (1,000 km).
•
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 needle enters the red
range.
•
If the automatic transmission begins to over-
heat, 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 regula-
tions).
•
Do not connect the trailer's brake system
directly to the vehicle's brake system.
•
More frequent vehicle maintenance is
required.
•
Remove the ball holder when the hitch is not
being used.
