Cold weather precautions
If you wish to check your car before the approach of cold weather, the f\
ollowing 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 section "Coolant".
The use of "recycled" antifreeze is not approved by Volvo. Different typ\
es of antifreeze must not
be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your car's radia\
tor. Your local Volvo
retailer stocks plenty of Volvo engine coolant to protect your car durin\
g 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 f\
uel line de-icer before refueling.
l The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-
weather starting as well as decreasing fuel consumption while the engine\
is warming up. For winter use,
5W-30 oil, particularly the synthetic type *, is recommended. Be sure to\
use good quality oil but do not
use this cold-weather oil for hard driving or in warm weather. See secti\
on "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 temperature drops. In very
cold weather, a poorly charged battery can freeze and be damaged. It is \
therefore advisable to check the
state of charge more frequently and spray an anti-rust oil on the batter\
y 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 136 for the location of the washer fluid reservoir). This is important sin\
ce dirt is often splashed on
the windshield during winter driving, requiring the frequent use of the \
washers and wipers. The Volvo
Washer 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.
W Winter/Wet driving mode - enhanced vehicle traction
l Mode W will only function if the gear selector is in the (D)rive posit\
ion.
l Press the button at the base of the gear selector to engage/disengage th\
is driving mode.
l An LED in the button will light up to indicate that W is engaged and this will also be displayed in the
instrument panel (see
page 27).
l This mode may be selected for starting/moving off on slippery roads.

General information
Your vehicle is equipped with tires according to the tire information la\
bel on the inside of the fuel
filler door.
The following is an example of a tire designation code: 225/55 R16
225 = tire width in mm.
55 = tire profile. This is the relationship (in percent) between the sect\
ion height and width of the tire.
R = radial tires.
16 = diameter in inches.
The tires have good road holding characteristics and offer good handling\
on dry and wet surfaces. It
should be noted however that the tires have been developed to give these\
features on snow/ice-free
surfaces. Certain models are equipped with "all-season" tires, which provide a som\
ewhat higher
degree of road holding on slippery surfaces than tires without the "all-\
season" rating. However,
for optimum road holding on icy or snow covered roads - we recommend suitable winter tires on all

spare tire other than the one that came with the car. The use of differe\
nt size wheels can seriously
damage your car's transmission or driveline.

pg. 111 Wheels and tires
Snow chains
Snow chains can be used on your Volvo with the following restrictions:
l Snow chains should be installed on front wheels only. Use only Volvo app\
roved snow chains.
l Special snow chains must be mounted on 215/55 R16. Consult your Volvo re\
tailer.
l 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. Sufficie\
nt clearances between chains
and brakes, suspension and body components must be maintained. Snow chai\
ns cannot be used on 17"
wheels*.
l Some strap-on type chains will interfere with brake components and there\
fore CANNOT be used.
l All Wheel Drive models:Snow chains should only be installed on the front wheels. Only chains
adapted for AWD models should be used.
Consult your Volvo retailer for additional snow chain information.
CAUTION:
l Check local regulations regarding the use of snow chains before installi\
ng.
l Always follow the chain manufacturer's installation instructions careful\
ly. Install chains as tightly as
possible and retighten periodically.
l Never exceed the chain manufacturer's specified maximum speed limit. In \
no case should you exceed
31 mph (50 km/h).
l Avoid bumps, holes or sharp turns when driving with snow chains.
l Vehicle handling can be adversely affected when driving with chains. Avo\
id fast maneuvering and
hard braking. Never allow the wheels to lock up during braking.
* V70R - Volvo offers specially designed chains that can be used on 225/\
45/R17 tires.

Tires for winter use:
Owners who live in or regularly travel through areas with sustained peri\
ods of snow or icy driving

conditions are strongly advised to fit suitable winter tires to help ret\
ain the highest degree of
traction. It is important to install winter tires on all four wheels to help retain traction during cornering,
braking, and accelerating. Failure to do so could reduce traction to an \
unsafe level or adversely affect
handling. Volvo does not recommend tire rotation. However, as with any o\
ther radial tires, if rotated, the
tires must be kept on the same side of the car so that they revolve in t\
he same direction as before
rotation.
Volvo recommends the use of winter tires with the following dimensions: \

Non-turbo models: 195/65 R15
Turbo models (not XC70 or V70R): 205/55 R16
XC70: 215/65 R16
V70R: 225/45/R17
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 car shou\
ld be driven as
smoothly as possible to give the studs the opportunity to seat properly \
in the tires. The tires should have
the same rotational direction throughout their entire lifetime. In other\
words, if you wish to rotate the
wheels, make sure that the same wheels are always on the same side of th\
e car.
NOTE: Please consult state or provincial regulations restricting the use of st\
udded winter tires before
installing such tires.
** Where permitted.

WARNING!
l The jack must correctly engage the bar in the jack attachment (A). The\
car's weight must not rest
on the jack attachment (B). See illustration on
page 115.
l Be sure the jack is on a firm, level, non-slippery surface.
l Never allow any part of your body to be extended under a car supported b\
y a jack.
l Use the jack intended for the car when replacing a wheel. For any other \
job, use stands to support
the side of the car being worked on.
l Apply the parking brake and put the gear selector in the (P)ark positi\
on.
l Block the wheels standing on the ground, use rigid wooden blocks or larg\
e stones.
l The jack should be kept well-greased.


pg. 115 Changing wheels


Attaching the jack
NOTE: To avoid excessive wear and the necessity of rebalancing, mark and reins\
tall wheels in the same
location and position as before removal. To lessen the chance of imbalan\
ce, each wheel hub is equipped
with a guide stud to ensure that a removed wheel can be reinstalled in i\
ts original position (as when
changing over to winter tires/wheels).
NOTE: Refer to
page 135 for hoisting the vehicle on a garage lift.
