CAUTION
l Engine damage will occur if water is drawn into the air cleaner.
l If the vehicle is driven through water deeper than 9 in (25 cm), water\
may enter the differential and
the transmission. This reduces the oil's lubricating capacity and may sh\
orten the service life of these
components.
l Do not allow the vehicle to stand in water up to the door sills longer t\
han absolutely necessary. This
could result in electrical malfunctions.
l If the engine has been stopped while the car is in water, do not attempt\
to restart the engine. Have the
car towed out of the water.
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 section "Coolant". The use
of "recycled" antifreeze is not approved by Volvo. Different types of an\
tifreeze 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 help protect your vehicle durin\
g cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of c\
ondensation 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 (t\
hinner oil) improves cold-weather
starting as well as decreasing fuel consumption while the engine is warm\
ing up. For winter use, 5W-30
oil, particularly the synthetic type
1, is recommended. Be sure to use good quality oil but do not use cold-
weather oil for hard driving or in warm weather. See
page 239 for more information.
l The load placed on the battery is greater during the winter since the wi\
ndshield 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 there\
fore advisable to check the state
of
1Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at owner request and
at additional charge. Please consult your Volvo retailer.

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 dri\
ving - see the chapter "Wheels
and tires."

General information
Your vehicle is equipped with tires according to the vehicle's tire info\
rmation placard on the B-pillar (the
structural member at the side of the vehicle, at the rear of the driver'\
s door opening), or on the inside of
the fuel filler door on Canadian models.
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 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 there is a ris\
k of altering the car'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.
WARNING
l The wheel and tire sizes for your are specified to meet stringent stabil\
ity and handling requirements.
Unapproved wheel/ tire size combinations can negatively affect your vehi\
cle's stability and handling.
Approved tire sizes are shown in the Tire inflation pressure tables on
pages 156 and 157.
l Any damage caused by installation of unapproved wheel/tire size combinat\
ions will not be covered
by your new vehicle warranty. Volvo assumes no responsibility for death,\
injury, or expenses that may
result from such installations.

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 prev\
ent alteration of the driving
characteristics of the vehicle.

General information
New Tires
Remember that tires are perishable goods. As of 2000, the manufacturing \
week and year (Department of
Transportation (DOT) stamp) will be indicated with 4 digits (e.g. 15\
02 means that the tire illustrated was
manufactured during week 15 of 2002).
Tire age
Tires degrade over time, even when they are not being used. It is recomm\
ended that tires generally be
replaced after 6 years of normal service. Heat caused by hot climates, f\
requent high loading conditions or
Ultra Violet (U.V) exposure can accelerate the aging process.

l Rim: The metal support (wheel) for a tire or a tire and tube assembly upo\
n which the tire beads are
seated.
l Maximum load rating: a figure indicating the maximum load in pounds and kilograms that can \
be
carried by the tire. This rating is established by the tire manufacturer\
.
l Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put
in the tire. This limit is set by the tire manufacturer.
l Recommended tire inflation pressure: inflation pressure, established by Volvo, which is based on the
type of tires that are mounted on a vehicle at the factory. This inflati\
on pressure is affected by the number
of occupants in the car, the amount of cargo, and the speed at which the\
vehicle will be driven for a
prolonged period.
This information can be found on the tire inflation placard(s) located\
on the driver's side B-pillar or on the
inside of the fuel filler door on Canadian models, and in the tire infla\
tion table in this chapter.
l Cold tires: The tires are considered to be cold when they have the same temperatur\
e as the surrounding
(ambient) air. This temperature is normally reached after the car has \
been parked for at least 3 hours.

ms for determining your vehicle's
weight ratings, with or without a trailer, from the vehicle's Federal/Ca\
nadian Motor Vehicle Safety
Standards (FMVSS/ CMVSS) label, and the vehicle's tire information pla\
card:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard\
equipment. It does not include
passengers, cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipm\
ent. When towing, trailer hitch
tongue load is also part of cargo weight.

The traction grade assigned to this tire is based on braking (straight-\
ahead) traction tests and is not a
measure of cornering (turning) traction.
WARNING
The traction grade assigned to this tire is based on braking (straight-\
ahead) traction tests and is not a
measure of cornering (turning) traction.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing\
the tire's resistance to the
generation of heat and its ability to dissipate heat when tested under c\
ontrolled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degener\
ate and reduce tire life, and
excessive temperature can lead to sudden tire failure.
The grade C corresponds to a minimum level of performance that all passe\
nger vehicle tires must meet
under the Federal Motor Safety Standard No. 109. Grades B and A represen\
t higher levels of performance
on the laboratory test wheel than the minimum required by law.
WARNING
The temperature grade for this tire is established for a tire that is pr\
operly inflated and not overloaded.
Excessive speed, under-inflation, or excessive loading, either separatel\
y or in combination, can cause
heat buildup and tire failure.

Snow chains, snow tires, studded 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 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.
l Some strap-on type chains will interfere with brake components and there\
fore CANNOT be used.
Consult your Volvo retailer for additional snow chain information.

There are two different types of wheel nut, depending on whether the whe\
els are steel or aluminum.
Steel rims - low nut
Steel rims are normally secured using the low type of nut, although stee\
l rims may also use the high type.
WARNING
Never use the short type of nut for aluminium wheels. This could cause t\
he wheel to come
loose.
Aluminum wheels - high nut
Only the high type of nut can be used for aluminum wheels. This is consi\
derably different from other
types of nut because it has a rotating conical thrust washer.
NOTE
This nut can also be used on steel
wheels.
Lockable wheel nut
If steel wheels with lockable wheel nuts are used in combination with wh\
eel covers, the lockable wheel
nut must be fitted to the stud nearest the air valve. The wheel cover ca\
nnot otherwise be installed on the
wheel.
