Towing a trailer
The maximum weights recommended by Volvo for trailers with brakes are shown in the table below.
NOTE:
l Recommended hitch tongue load: not more than 10% of the trailer's weight\
. The trailer load should be positioned
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 permissible weights indicated in the table above.
l When towing trailers without brakes, the maximum permissible trailer weight is 1,700 lbs (750 kg).\
l If necessary, redistribute the weight of any cargo in the trailer to avo\
id excessive weight on the trailer hitch.
l The maximum trailer weight listed in the table for All Wheel Drive model\
s, 5,000 lbs (2250 kg) is only applicable when
there are not more than two occupants in the vehicle, in the front seats\
, with a combined weight of 300 lbs (135 kg), with
no other cargo in the vehicle.
l 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 r\
ow of seats, with a combined weight of 600 lbs (270
kg), with no other cargo in the vehicle.

Towing a trailer
l Please be aware that the load on the trailer hitch is part of the vehicl\
e's total load carrying capacity. The amount of cargo
in the vehicle and the trailer must be limited so that the gross vehicle\
weight and maximum permissible rear axle weight
(see
page 209) are not exceeded.
l Vehicles used for towing a trailer on a regular basis, or for long-dista\
nce highway towing should be equipped with an
automatic transmission oil cooler and Volvo's automatic self-leveling sy\
stem for the rear suspension. Consult your Volvo
retailer.
l Volvo recommends the use of Volvo trailer hitches that are specially des\
igned for the vehicle.
l All Volvo models are equipped with energy-absorbing shock-mounted bumper\
s. Trailer hitch installation should not
interfere with the proper operation of this bumper system.
l Increase tire pressure to recommended full inflation pressure. See chapt\
er "Wheels and tires."
l When your vehicle is new, avoid towing heavy trailers during the first 6\
20 miles (1,000 km).
l Engine and transmission are subject to increased loads. Therefore, engin\
e coolant temperature should be closely

Load carrier cover
The vehicle's ignition key or the stud on the edge of the supplied torqu\
e wrench can be used to undo or tighten the cover.
Turn a quarter turn (90 degrees). See illustration.
pg. 143 Starting and driving
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, t\
he following advice is worth noting:
l Make sure that the engine coolant contains 50 percent antifreeze. Any ot\
her mixture will reduce freeze protection. This
gives protection against freezing down to -31°F (-35°C). See sec\
tion "Coolant". The use of "recycled" antifreeze is not
approved by Volvo. Different types of antifreeze must not be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your vehicle's r\
adiator. Your Volvo retailer stocks plenty of
Volvo engine coolant to protect your vehicle during cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of condensation in the tank. \
In addition, in extremely
cold weather conditions it is worthwhile to add fuel line de-icer before\
refueling.
l The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-weat\
her starting as well
as decreasing fuel consumption while the engine is warming up. For winte\
r use, 5W-30 oil, particularly the synthetic type
1,
is recommended. Be sure to use good quality oil but do not use cold-weat\
her oil for hard driving or in warm weather. See
section "Engine oil" for more information.
l The load placed on the battery is greater during the winter since the windshield wipers, lighting, etc\
. are used more
often. Moreover, the capacity of the battery decreases as the temperatur\
e drops. In very cold weather, a poorly charged
battery can freeze and be damaged. It is therefore advisable to check th\
e state of charge more frequently and spray an
antirust oil on the battery posts.
l Volvo recommends the use of snow tires on all four wheels for winter driving - see section "Wheels and tires."\
l To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see page 188 for the
location of the washer fluid reservoir). This is important since dirt i\
s often splashed on the windshield during winter
driving, requiring the frequent use of the washers and wipers. Volvo Was\
her Solvent should be diluted as follows:
- Down to 14° F (-10° C): 1 part washer solvent and 4 parts water
- Down to 5° F (-15° C): 1 part washer solvent and 3 parts water
- Down to 0° F (-18° C): 1 part washer solvent and 2 parts water
- Down to -18° F (-28° C): 1 part washer solvent and 1 part water
l Use Volvo Teflon Lock Spray in the locks.
NOTE: Avoid the use of de-icing sprays as they can cause damage to the locks.

holding on icy or snow-covered roads, we recommend suitable winter tires\
on all four wheels.
When replacing tires, be sure that the new tires are the same size desig\
nation, type (radial) and
preferably from the same manufacturer, on all four wheels. Otherwise the\
re is a risk of altering the
vehicle's roadholding and handling characteristics.
Storing wheels and tires
When storing complete wheels (tires mounted on rims), they should be s\
uspended off the floor or placed
on their sides on the floor.
Tires not mounted on rims should be stored on their sides or standing up\
right, but should not be
suspended. CAUTION!
Tires should preferably be stored in a cool, dry, dark place, and should\
never be stored in close
proximity to solvents, gasoline, oils, etc.
Tread wear indicator
The tires have wear indicator strips running across or parallel to the t\
read. The letters TWI are printed on
the side of the tire. When approximately 1/16" (1.6 mm) is left on the\
tread, these strips become visible
and indicate that the tire should be replaced. Tires with less than 1/16\
" (1.6 mm) tread offer very poor
traction.
When replacing worn tires, it is recommended that the tire be identical \
in type (radial) and size as the
one being replaced. Using a tire of the same make (manufacturer) will \
prevent alteration of the driving
characteristics of the vehicle.

Engine oil
Oil specifications
Engine oil must meet the minimum ILSAC specification GF-3, API SL, and A\
CEA A1/ B1. Lower
quality oils may not offer the same fuel economy, engine performance, or\
engine protection.
Volvo recommends
.
Depending on your driving habits, premium or synthetic oils may provide \
superior fuel economy and
engine protection. Consult your Volvo retailer for recommendations on pr\
emium or synthetic oils.
Oil additives must not be used.
NOTE: Synthetic oil is not used when the oil is changed at the normal mainten\
ance services. This oil is
only used at customer request, at additional charge. Please consult your\
Volvo retailer.
Oil viscosity (stable ambient temperatures)
Operation in hot climates
When temperatures exceed 86° F (30° C) in your area, Volvo recom\
mends, for the protection of your
engine, that you use a heavier weight oil, such as such as SAE 5W-40 or \
0W-40. See the viscosity chart.
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when t\
emperatures do not exceed 86° F
(30° C), SAE 5W-30 will provide good fuel economy and engine protec\
tion. See the viscosity chart.
Extreme engine operation
Synthetic oils meeting SAE 0W-30 or 0W-40 and complying with oil quality\
requirements are
recommended for driving in areas of sustained temperature extremes (hot\
or cold), when towing a trailer
over long distances, and for prolonged driving in mountainous areas.
