Tire rotationYour vehicle has no recommended tire rota-
tion. The following information is intended to
help you understand why.Tread setAs a tire ages and the rubber cures, front and
rear tires set at different angles. Therefore, if
tires are rotated, the tread will eventually set at
an angle that is a compromise. Even if ride,
handling, and road noise may still seem
acceptable, they may not be optimal. Further,
tires that are rotated, but not on a regular basis,
may actually cause more tire noise, faster tire
wear, and unpleasant changes in steering feel
and vehicle handling.
A tire that can fully adapt to its position will
provide better steering feel, lower tire noise,
and better fuel economy.Braking stability performanceYour vehicle is driven mainly by the front tires,
which will wear faster. This can be beneficial.
Having more tread on the rear tires will help
reduce oversteer. Oversteer is when a vehicle
wants to keep turning because of momentum
and dynamic forces on its suspension.Suspension wear diagnosticsEvery suspension needs periodic inspection
and maintenance. A tire's wear pattern can be
an aid in detecting a suspension problem. Each
tire, if left in place, tells a story about the sus-pension. Tire rotation, on the other hand, could
make suspension wear harder to detect. Early
detection is very important, because suspen-
sion problems can make tire wear worse.
If you do rotate your tires…Please follow the tire manufacturer's recom-
mendations, as outlined in the tire manufactur-
ers tire warranty pamphlet.
Your Volvo retailer can also provide guidance
based on your particular driving circumstan-
ces.Changing a wheel
G017464
Location of jack and toolsSpare wheelThe spare wheel (Temporary spare) is only
intended for temporary use. Replace the sparewheel with a normal wheel as soon as possible.
The car's handling may be altered by the use
of the spare wheel. The correct tire pressure for
the spare wheel is stated in the tire pressure
tables on pages 248 and 249.
WARNING
Current legislation prohibits the use of the
“Temporary Spare” tire other than as a tem-
porary replacement for a punctured tire. It
must be replaced as soon as possible by a
standard tire. Road holding and handling
may be affected with the “Temporary
Spare” in use.
CAUTION
The vehicle must never be driven with more
than one temporary spare wheel.The spare wheel is located in the spare wheel
well with the rim side down. There are two foam
blocks, one under the spare wheel and one
over/inside. The upper one contains all tools.
The same bolt runs through to secure the spare
wheel and the foam blocks.Taking out the spare wheel1. Fold the rear edge of the floor mat forward.
2. Open the floor hatch.

fully. Solvents or stain removers should not be
used.
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
Automatic car wash•
We do NOT recommend washing your car
in an automatic wash during the first six
months (because the paint will not have
hardened sufficiently).
•
An automatic wash is a simple and quick
way to clean your car, but it is worth
remembering that it may not be as thor-
ough as when you yourself go over the car
with sponge and water. Keeping the under-
body clean is most important, especially in
the winter. Some automatic washers do
not have facilities for washing the under-
body.
CAUTION
•
Before driving into an automatic car
wash, turn off the optional rain sensor
to avoid damaging the windshield wip-
ers.
•
Make sure that side view mirrors, auxil-
iary lamps, etc, are secure, and that any
antenna(s) are retracted or removed.
Otherwise there is risk of the machine
dislodging them.
•
Chromed wheels: Clean chrome-
plated wheels using the same deter-
gents used for the body of the vehicle.
Aggressive wheel-cleaning agents can
permanently stain chrome-plated
wheels.WARNING
•
When the vehicle is driven immediately
after being washed, apply the brakes,
including the parking brake, 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.
Exterior lightingCondensation may form temporarily on the
inside of the lenses of exterior lights such asheadlights, fog lights, or taillights. 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 waxes can
be purchased today. These waxes are easy
to use and produce a long-lasting, high-
gloss finish that protects the bodywork
against oxidation, road dirt and fading.
•
Do not polish or wax your vehicle in direct
sunlight (the surface of the vehicle should
not be warmer than 113 °F (45 °C).
