2010 SUBARU LEGACY Owners Manual

&Tire replacement
The wheels and tires are important and
integral parts of your vehicle ’s design;
they cannot be changed arbitrarily. The
tires fitted as standard equipment are
optimally matched to the characteristics
of the vehicle and were selected to give
the best possible combination of running
performance, ride comfort, and service
life. It is essential for every tire to have a
size and construction matching those
shown on the tire placard and to have a
speed symbol and load index matching
those shown on the tire placard.
Using tires of a non-specified size detracts
from controllability, ride comfort, braking
performance, speedometer accuracy and
odometer accuracy. It also creates incor-
rect body-to-tire clearances and inappro-
priately changes the vehicle ’sground
clearance.
All four tires must be the same in terms of
manufacturer, brand (tread pattern), con-
struction, and size. You are advised to
replace the tires with new ones that are
identical to those fitted as standard equip-ment.
For safe vehicle operation, SUBARU
recommends replacing all four tires at
the same time.WARNING
. All four tires must be the same in
terms of manufacturer, brand
(tread pattern), construction, de-
gree of wear, speed symbol, load
index and size. Mixing tires of
different types, sizes or degrees
of wear can result in damage to
the vehicle ’s power train. Use of
different types or sizes of tires
can also dangerously reduce
controllability and braking per-
formance and can lead to anaccident.
. Use only radial tires. Do not use
radial tires together with belted
bias tires and/or bias-ply tires.
Doing so can dangerously re-
duce controllability, resulting in
an accident. &
Wheel replacement
When replacing wheels due, for example,
to damage, make sure the replacement
wheels match the specifications of the
wheels that are fitted as standard equip-
ment. Replacement wheels are available
from SUBARU dealers.
WARNING
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could
interfere with brake caliper opera-
tion and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of
vehicle control could lead to anaccident. Maintenance and service

11-42Maintenance and service
Aluminum wheels
Aluminum wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety. .When any of the wheels is removed
and replaced for tire rotation or to change
a flat, always check the tightness of the
wheel nuts after driving approximately 600
miles (1,000 km). If any nut is loose,
tighten it to the specified torque. . Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the wheel. . Never let the wheel rub against sharp
protrusions or curbs.. When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for aluminum wheels. Windshield washer fluid
CAUTION
Never use engine coolant as washer
fluid because it could cause paintdamage.
If you spray washer fluid on the windshield
but the windshield washer fluid warning
light illuminates or the supply of washer
fluid runs out, add washer fluid in the tank.
Remove the washer tank filler cap, then
add fluid until it reaches the “FULL ”mark
on the tank.
Use windshield washer fluid. If windshield
washer fluid is unavailable use clean
water.

In areas where water freezes in winter,
use an anti-freeze type windshield washer
fluid. SUBARU Windshield Washer Fluid
contains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the followingtable.Washer Fluid
Concentration Freezing
Temperature
30% 10.48F( 12 8C)
50% 48F( 20 8C)
100% 49 8F( 45 8C)
CAUTION
Never use engine coolant as washer
fluid because it could cause paintdamage.
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if the concentration of the fluid remaining in
the piping is too low for the outside
temperature, it may freeze and block thenozzles.
CAUTION
. Adjust the washer fluid concen-
tration appropriately for the out-
side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.
. State or local regulations on
volatile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle ’s paint, wiper blades
or washer system. Replacement of wiper blades
Grease, wax, insects, or other materials
on the windshield or the wiper blade
results in jerky wiper operation and streak-
ing on the glass. If you cannot remove the
streaks after operating the windshield
washer or if the wiper operation is jerky,
clean the outer surface of the windshield
(or rear window) and the wiper blades
using a sponge or soft cloth with a neutral
detergent or mild-abrasive cleaner. After
cleaning, rinse the windshield and wiper
blades with clean water. The windshield is
clean if beads do not form when you rinse
the windshield with water.
CAUTION
. Do not clean the wiper blades
with gasoline or a solvent, such
as paint thinner or benzine. This
will cause deterioration of the
wiper blades.
. When you wish to raise the
passenger-side wiper arm, first
raise the driver-side wiper arm.
Otherwise, the passenger-side
wiper assembly and driver-side
wiper assembly will touch each
other, possibly resulting inscratches. Maintenance and service

11-44Maintenance and service
.Return the passenger-side wiper
arm to its original position before
returning the driver-side wiper
arm to its original position.
Otherwise, the passenger-side
wiper assembly and driver-side
wiper assembly will touch each
other, possibly resulting inscratches.
. When returning the raised wipers
to the original positions, return
the wipers slowly on the wind-
shield by hand. Returning the
wipers from the detached posi-
tions by the spring operation
might change the shape of the
wiper arm or scratch the wind-shield.

Battery
WARNING
. Before beginning work on or near
any battery, be sure to extinguish
all cigarettes, matches, and light-
ers. Never expose a battery to an
open flame or electric sparks.
Batteries give off a gas which is
highly flammable and explosive.
. For safety, in case an explosion
does occur, wear eye protection
or shield your eyes when work-
ing near any battery. Never lean
over a battery.
. Do not let battery fluid contact
eyes, skin, fabrics, or paint be-
cause battery fluid is a corrosive
acid. If battery fluid gets on your
skin or in your eyes, immediately
flush the area with water thor-
oughly. Seek medical help imme-
diately if acid has entered theeyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water,
and seek medical attention im-
mediately.
. To lessen the risk of sparks, Maintenance and service

remove rings, metal watchbands,
and other metal jewelry. Never
allow metal tools to contact the
positive battery terminal and any-
thing connected to it WHILE you
are at the same time in contact
with any other metallic portion of
the vehicle because a short cir-
cuit will result.
. Keep everyone including children
away from the battery.
. Charge the battery in a well-
ventilated area.
. Battery posts, terminals, and re-
lated accessories contain lead
and lead compounds, chemicals
known to the State of California
to cause cancer and reproductive
harm. Batteries also contain
other chemicals known to the
State of California to cause can-
cer. Wash hands after handling.
CAUTION
Never use more than 10 amperes
when charging the battery because
it will shorten battery life.
It is unnecessary to periodically check the
battery fluid level or periodically refill with distilled water.
Fuses
CAUTION
Never replace a fuse with one hav-
ing a higher rating or with material
other than a fuse because serious
damage or a fire could result.
The fuses are designed to melt during an
overload to prevent damage to the wiring
harness and electrical equipment. The
fuses are located in two fuse boxes.
One is located under the instrument panel
behind the fuse box cover on the driver ’s
seat side. To remove the cover, pull it out.
