Low nut.
High nut.
There are two different types of wheel nut,
depending on whether the wheels are steel or
aluminum.
Steel rims – low nutSteel rims are normally secured using the low
type of nut, although steel rims may also use
the high type.
WARNING
Never use the short type of nut for alumi-
nium wheels. This could cause the wheel to
come loose.
Aluminum wheels – high nutOnly the high type of nut can be used for alu-
minum wheels. This is considerably different
from other types of nut because it has a rotat-
ing conical thrust washer.
NOTE
This nut can also be used on steel wheels.
Lockable wheel nutIf steel wheels with lockable wheel nuts are
used in combination with wheel covers, the
lockable wheel nut must be fitted to the stud
nearest the air valve. The wheel cover cannot
otherwise be installed on the wheel.

WARNING
•The jack must correctly engage the jack
attachment.
•Be sure the jack is on a firm, level, non-
slippery surface.
•Never allow any part of your body to be
extended under a car supported by a
jack.
•Use the jack intended for the car when
changing a tire. For any other job, use
stands to support the car.
•Apply the parking brake and put the
gear selector in the Park (P) position or
reverse on models with a manual trans-
mission.
•Block the wheels standing on the
ground, use rigid wooden blocks or
large stones.
•The jack should be kept well-greased
and clean, and should not be damaged.
•No objects should be placed between
the base of jack and the ground, or
between the jack and the attachment
bar on the vehicle.
Installing the wheel
1. Clean the contact surfaces on the wheel
and hub.
2. Lift the wheel and place it on the hub.
3. Install the wheel nuts and tighten hand-
tight. 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).
5. Install the wheel cover (where applicable).
Returning the jack to its storage space
The jack (certain models) and tools should be
returned to their correct storage places after
use.
•On vehicles equipped with a jack and
spare wheel, the jack should be cranked
down and returned to its storage position
after use.
•On vehicles equipped with the tire sealing
system, the jack should be cranked down
as far as possible and returned to its stor-
age 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.

4. Put on the gloves included in the tire seal-
ing system.
WARNING
Contact with the sealing compound may
cause skin irritation. If contact occurs, wash
the affected area immediately with soap and
water.
5. Unscrew the orange cover over the bottle
holder and unscrew the cap on the bottle
of sealing compound.
NOTE
Do not break the seal on the bottle. This
occurs automatically when the bottle is
screwed into the holder.
6. Screw the bottle into the bottle holder.
WARNING
The bottle is equipped with a catch to keep
it securely in place and help prevent sealing
compound leakage. Once in place, the bot-
tle cannot be unscrewed. This must be done
by a trained and qualified Volvo service
technician.
7. Remove the valve cap from the tire’s infla-
tion valve and screw the tire sealing sys-
tem’s hose connector onto the valve as
tightly as possible by hand.
8. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
9. Start the vehicle’s engine.
10. Start the tire sealing system’s compressor
by pressing the on/off switch to position I.
WARNING
•Never stand next to the tire being inflated
when the compressor is in operation.
•If cracks, bubbles, etc. form on the tire,
switch off the compressor immediately.
•If there is visible damage to the sidewall
or the rim, the tire cannot be repaired.
The vehicle should not be driven if this
occurs. Contact a towing service or
Volvo On Call Roadside Assistance if
applicable.
NOTE
The air pressure gauge will temporarily
show an increase in pressure to approxi-
mately 88 psi (6 bar) while the sealing com-
pound is being pumped into the tire. The
pressure should return to a normal level
after approximately 30 seconds.
11. Within seven minutes, inflate the tire to
between 22—44 psi (1.8—3.0 bar). Switch
off the compressor briefly to get a clear
reading from the pressure gauge. The
compressor should not be used for more
than 10 minutes at a time to avoid over-
heating.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
If the pressure remains below 22 psi
(1.8 bar) after approximately seven minutes,
turn off the compressor. In this case, the
hole is too large to be sealed and the vehicle
should not be driven.

08 Car care
Washing and cleaning the car
08

205
Automatic washing – simple and quickWe do NOT recommend washing your car in an
automatic wash during the first six months
(because the paint will not have hardened suf-
ficiently).
An automatic wash is a simple and quick way
to clean your car, but it is worth remembering
that it may not be as thorough as when you
yourself go over the car with sponge and water.
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.

09 Maintenance and servicing
Battery09

223 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.
