Introduction
Volvo recommends the use of Volvo trailer
hitches that are specially designed for the vehi-
cle.
NOTE
See page 295 for the maximum trailer and
tongue weights recommended by Volvo.
•Observe the legal requirements of the
state/province in which the vehicles are
•All Volvo models are equipped with
energy-absorbing shock-mounted bump-
ers. 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 considera-
tion:
•Increase tire pressure to recommended full
pressure. See the tire inflation tables
beginning on page 231.
•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 watchedwhen driving in hot climates or hilly terrain.
Use a lower gear and turn off the air con-
ditioner if the temperature gauge needle
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 opera-
tion.
•Hauling a trailer affects handling, durabil-
ity, 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 author-
ized Volvo retailer for correct installa-
tion.
•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 vehicle. The safety wire should
never be fastened to or wound around
the drawbar ball.
