Installing the wheel
1. Clean the contact surfaces between the
wheel and hub.
2. Lift the wheel and place it on the hub.
3. Install the wheel nuts and hand-tighten
them. Using the lug wrench, tighten cross-
wise until all nuts are snug.
4. Lower the vehicle to the ground and alter-
nately tighten the bolts crosswise to
81 ft. lbs. (110 Nm) or 96 ft. lbs. (130 Nm),
depending on the type of wheel/wheel nuts
used on your vehicle. See also 191 for
additional information.
5. Install the wheel cover (where applicable).
See page 192 for information on returning the
jack and tools to their proper storage positions.
On vehicles equipped with the tire sealing sys-
tem, the jack should be cranked down as far as
possible and returned to its storage position in
the foam block.
WARNING
The jack and any tools should always be
returned to their proper storage compart-
ments after use to help keep them securely
in place in the event of sudden braking, etc.

08 Car care
Washing and cleaning the car
08

207
Keeping the underbody clean is most impor-
tant, especially in the winter. Some automatic
washers do not have facilities for washing the
underbody.
CAUTION
•Before driving into an automatic car
wash, turn off the optional rain sensor to
avoid damaging the windshield wipers.
•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 car 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.
Exterior lightingCondensation may form temporarily on the
inside of the lenses of exterior lights such as
headlights, 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).
CAUTION
Volvo does not recommend the use of long-
life or durable paint protection coatings,
some of which may claim to prevent pitting,
fading, oxidation, etc. These coatings have
not been tested by Volvo for compatibility
with your vehicle's clear coat. Some of them
may cause the clear coat to soften, crack,
or cloud. Damage caused by application of
paint protection coatings may not be cov-
ered under your vehicle's paint warranty.
Upholstery care
FabricClean with soapy water or a detergent. For
more difficult spots caused by oil, ice cream,
shoe polish, grease, etc., use a clothing/fabric
stain remover. Consult your Volvo retailer.
Interior plastic componentsCleaning interior plastic components should
be done with a cleaning agent specially
designed for this purpose. Consult your Volvo
retailer.
Alcantera™ suede-like materialSuede-like upholstery can be cleaned with a
soft cloth and mild soap solution.

223 Replacing windshield wiper blades
G020330
1. Fold out the wiper arm.
2. Press the button on the wiper blade attach-
ment and pull straight out (1), parallel with
the wiper arm.

on the passenger's side.
G020329
Keeping the windshield wiper blades clean
helps improve visibility and prolongs the serv-
ice life of the wiper blades. See page 206 for
washing instructions.

09 Maintenance and servicing
Battery 09
224
Battery maintenance
Driving habits and conditions, climate, the
number of starts, etc., all affect the service life
and function of the battery. In order for your
battery to perform satisfactorily, keep the fol-
lowing in mind:
Check the fluid level in each cell in the battery
every 24 months or every 15,000
1 miles
(24,000 km), whichever is sooner.
•Use a screw driver to open the caps or
cover and a flashlight to inspect the level.
•If necessary, add distilled water. The level
should never be above the indicator.
•The fluid level should be checked if the
battery has been recharged.
•After inspection, be sure the cap over each
battery cell or the cover is securely in
place.
•Check that the battery cables are correctly
connected and properly tightened.
•Never disconnect the battery when the
engine is running, or when the key is in the
ignition. This could damage the vehicle's
electrical system.
•The battery should be disconnected from
the vehicle when a battery charger is used
directly on the battery.
•To help keep the battery in good condition,
the vehicle should be driven for at least 15
minutes a week or connected to a charger
with an automatic charging function.
•If the battery is fully discharged a number
of times, this may shorten its service life.
Keeping the battery fully charged helps
prolong its service life.
•The service life of a battery is affected by
factors such as driving conditions and cli-
mate. Extreme cold may also further
decrease the battery’s starting capacity.
•Because the battery’s starting capacity
decreases with time, it may be necessary
to recharge it if the vehicle is not driven for
an extended period of time or if the vehicle
is usually only driven short distances.
