Points to keep in mind when towing a
trailer
•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 excessive
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 occupants in the vehi-
cle, in the front seats, with a combined
weight of 300 lbs (135 kg), with no other
cargo in the vehicle.
•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.
•Vehicles used for towing a trailer on a reg-
ular basis, or for long-distance highway
towing should be equipped with an auto-
matic 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 bump-
ers. 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 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.
•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.
•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).

06 Starting and driving
Before a long distance trip
06
159
It is always worthwhile to have your vehicle
checked by a trained and qualified Volvo serv-
ice technician before driving long distances.
Your retailer or service technician will also be
able to supply you with bulbs, fuses, spark
plugs and wiper blades for your use in the event
that problems occur.
As a minimum, the following items should be
checked before any long trip:
•Check that engine runs smoothly and that
fuel consumption is normal.
•Check for fuel, oil, and fluid leakage.
•Check transmission oil level1.
•Check condition of drive belts.
•Check state of the battery's charge.
•Examine tires carefully (the spare tire as
well), and replace those that are worn.
Check tire pressures.
•The brakes, front wheel alignment, and
steering gear should be checked by a
trained and qualified Volvo service techni-
cian only.
•Check all lights, including high beams.
•Reflective warning triangles are legally
required in some states/provinces.
•Have a word with your Volvo retailer if you
intend to drive in countries where it may be
difficult to obtain the correct fuel.
•Consider your destination. If you will be
driving through an area where snow or ice
are likely to occur, consider snow tires.
1To prevent injury from contact with hot surfaces, do not inspect your vehicle’s transmission fluid yourself. Have your vehicle’s transmission fluid level inspected by a qualified Volvo service technician.

07 Wheels and tires
Snow chains, snow tires, studded tires

Snow chains
Snow chains can be used on your Volvo with
the following restrictions:
•Snow chains should be installed on front
wheels only. Use only Volvo approved
snow chains.
•If accessory, aftermarket or "custom" tires
and wheels are installed and are of a size
different than the original tires and wheels,
chains in some cases CANNOT be used.
Sufficient clearances between chains and
brakes, suspension and body components
must be maintained.
•Some strap-on type chains will interfere
with brake components and therefore
CANNOT be used.
•All Wheel Drive models: Snow chains
should only be installed on the front
wheels.
Consult your Volvo retailer for additional snow
chain information.
CAUTION
•Check local regulations regarding the
use of snow chains before installing.
•Always follow the chain manufacturer's
installation instructions carefully. Install
chains as tightly as possible and
retighten periodically.
•Never exceed the chain manufacturer's
specified maximum speed limit. (Under
no circumstances should you exceed
31 mph (50 km/h)).
•Avoid bumps, holes or sharp turns
when driving with snow chains.
•The handling of the vehicle can be
adversely affected when driving with
chains. Avoid fast or sharp turns as well
as locked wheel braking.
Snow tires, studded tires1
Tires for winter use:
•Owners who live in or regularly commute
through areas with sustained periods of
snow or icy driving conditions are strongly
advised to fit suitable winter tires to help
retain the highest degree of traction.
•It is important to install winter tires on all
four wheels to help retain traction duringcornering, braking, and accelerating. Fail-
ure to do so could reduce traction to an
unsafe level or adversely affect handling.
•Do not mix tires of different design as this
could also negatively affect overall tire road
grip.
•Winter tires wear more quickly on dry roads
in warm weather. They should be removed
when the winter driving season has ended.
•Studded tires should be run-in
300-600 miles (500-1000 km) during which
the vehicle should be driven as smoothly
as possible to give the studs the opportu-
nity to seat properly in the tires. The tires
should have the same rotational direction
throughout their entire lifetime.
NOTE
Please consult state or provincial regula-
tions restricting the use of studded winter
tires before installing such tires.

08 Car care
Washing and cleaning the vehicle
08

195
CAUTION
•Avoid waxing or polishing plastic or rub-
ber components
•Polishing chromed strips can wear
away or damage the surface
•Polishes containing abrasive sub-
stances should not be used
NOTE
When washing the vehicle, remember to
remove dirt from the drain holes in the doors
and sills.
WARNING
•When the vehicle is driven immediately
after being washed, apply the brakes
several times in order to remove any
moisture from the brake linings.
•Engine cleaning agents should not be
used when the engine is warm. This
constitutes a fire risk.
Automatic washing – simple and quick
•We do NOT recommend washing your
vehicle in an automatic wash during thefirst six months (because the paint will not
have hardened sufficiently).
•An automatic wash is a simple and quick
way to clean your vehicle, but it is worth
remembering that it may not be as thor-
ough as when you yourself go over the
vehicle with sponge and water. Keeping
the underbody clean is most important,
especially in the winter. Some automatic
washers do not have facilities for washing
the underbody.
•Before driving into an automatic car wash,
make sure that side view mirrors, auxiliary
lamps, etc, are secure, and that any
antenna(s) are retracted or removed. Oth-
erwise there is risk of the machine dislodg-
ing them.
Exterior lightingCondensation may form temporarily on the
inside of the lenses of exterior lights such as
headlights, fog lights, or tail lights. This is nor-
mal and the lights are designed to withstand
moisture. Normally, condensation will dissi-
pate after the lights have been on for a short
time.
Polishing and waxing
•Normally, polishing is not required during
the first year after delivery, however, wax-
ing may be beneficial.
•Before applying polish or wax the vehicle
must be washed and dried. Tar spots can
be removed with kerosene or tar remover.
Difficult spots may require a fine rubbing
compound.
•After polishing use liquid or paste wax.
•Several commercially available products
contain both polish and wax.
•Waxing alone does not substitute for pol-
ishing a dull surface.
•A wide range of polymer-based car waxes
can be purchased today. These waxes are
easy to use and produce a long-lasting,
high-gloss finish that protects the body-
work against oxidation, road dirt and fad-
ing.
•Do not polish or wax your vehicle in direct
sunlight (the surface of the vehicle should
not be warmer than 113° F (45° C).
