NOTE
•
Recommended hitch tongue load:
not more than 10% of the trailer's
weight. The trailer load should be posi-
tioned so that it does not shift and the
tongue load should be 10% of the trail-
er's weight. However, the tongue load
should not exceed the maximum per-
missible weights indicated in the table
above.
•
When towing trailers without brakes,
the maximum permissible trailer weight
is 1,700 lbs (750 kg).
•
If necessary, redistribute the weight of
any cargo in the trailer to avoid exces-
sive weight on the trailer hitch.
•
The maximum trailer weight listed in the
table for All Wheel Drive models,
5,000 lbs (2250 kg) is only applicable
when there are not more than two occu-
pants in the vehicle, in the front seats,
with a combined weight of 300 lbs
(135 kg), with no other cargo in the vehi-
cle.
•
The maximum weight listed for Front
Wheel Drive models, 4,000 lbs (1800 kg)
is only applicable when there are not
more than four occupants in the vehicle,
in the front seats and second row of
seats, with a combined weight of
600 lbs (270 kg), with no other cargo in
the vehicle.
NOTE
•
Vehicles used for towing a trailer on a
regular basis, or for long-distance high-
way towing should be equipped with an
automatic transmission oil cooler and
Volvo's automatic self-leveling system
for the rear suspension. Consult your
Volvo retailer.
•
Volvo recommends the use of Volvo
trailer hitches that are specially
designed for the vehicle.
•
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.
•
Increase tire pressure to recommended
full inflation pressure. See chapter
"Wheels and tires."
•
When your vehicle is new, avoid towing
heavy trailers during the first 620 miles
(1,000 km).
•
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.

NOTE
•
If the automatic transmission begins to
overheat, a message will be displayed
in the text window.
•
Hauling a trailer affects handling, dura-
bility, and economy.
•
It is necessary to balance trailer brakes
with the towing vehicle brakes to pro-
vide a safe stop (check and observe
state/local regulations).
•
Do not connect the trailer's brake sys-
tem directly to the vehicle's brake sys-
tem.
•
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.
NOTE
•
When parking the vehicle with a trailer
on a hill, apply the parking brake before
putting the gear selector in P. When
starting on a hill, put the gear selector in
D before releasing the parking brake.
Always follow the trailer manufacturer's
recommendations for wheel chocking.
•
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).
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 a trained and qualified
Volvo service technician 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 vehicle. The safety wire should
never be fastened to or wound around
the drawbar ball.
Smoother starts with a trailerModels equipped with the V8-engine and the
6-speed automatic transmission have a built-
in function that reduces acceleration slightly in
first gear when the vehicle is towing a trailer.
This is done to help avoid wheel spin and to
make starting off smoother.•
This function is activated when the trailer's
electrical connector is plugged into the
