Jump starting
WARNING
.Battery fluid is SULFURIC ACID.
Do not let it come in contact with
the eyes, skin, clothing or the
vehicle.
If battery fluid gets on you, thor-
oughly flush the exposed area
with water immediately. Get med-
ical help if the fluid has entered
your eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water,
and obtain immediate medical
help.
Keep everyone including chil-
dren away from the battery.
.The gas generated by a battery
explodes if a flame or spark is
brought near it. Do not smoke or
light a match while jump starting.
.Never attempt jump starting if the
discharged battery is frozen. It
could cause the battery to burst
or explode.
.Whenever working on or around a
battery, always wear suitable eyeprotectors, and remove metal
objects such as rings, bands or
other metal jewelry.
.Be sure the jumper cables and
clamps on them do not have
loose or missing insulation.
Do not jump start unless cables
in suitable condition are avail-
able.
.A running engine can be danger-
ous. Keep your fingers, hands,
clothing, hair and tools away
from the cooling fan, belts and
any other moving engine parts.
Removing rings, watches and
ties is advisable.
.Jump starting is dangerous if it
done incorrectly. If you are un-
sure about the proper procedure
for jump starting, consult a com-
petent mechanic.
When your vehicle does not start due to a
run down (discharged) battery, the vehicle
may be jump started by connecting your
battery to another battery (called the
booster battery) with jumper cables.
&How to jump start1. Make sure the booster battery is 12
volts and the negative terminal is
grounded.
2. If the booster battery is in another
vehicle, do not let the two vehicles touch.
3. Turn off all unnecessary lights and
accessories.
4. Connect the jumper cables exactly in
the sequence illustrated.

Exterior care&Washing
CAUTION
TYPE RA: Do not use automatic car
washes. Doing so may damage the
rear wing or its finish.
CAUTION
.When washing the vehicle, the
brakes may get wet. As a result,
the brake stopping distance will
be longer. To dry the brakes, drive
the vehicle at a safe speed while
lightly depressing the brake ped-
al to heat up the brakes.
.Do not wash the engine compart-
ment and area adjacent to it. If
water enters the engine air intake
or electrical parts, it will cause
engine trouble or a malfunction
of electrical equipment.
.When washing the inner fenders,
underbody, bumpers and pro-
truding objects such as exhaust
pipes and exhaust finishers, be
careful to prevent injuries from
contacting sharp ends..Do not use any organic solvents
when washing the surface of the
bulb assembly cover. However, if
a detergent with organic solvents
is used to wash the cover sur-
face, completely rinse off the
detergent with water. Otherwise,
the cover surface may be da-
maged.
NOTEWhen having your vehicle washed in an
automatic car wash, make sure before-
hand that the car wash is of suitable
type.
The best way to preserve your vehicle’s
beauty is frequent washing. Wash the
vehicle at least once a month to avoid
contamination by road grime.
Wash dirt off with a wet sponge and plenty
of lukewarm or cold water. Do not wash the
vehicle with hot water and in direct sun-
light.
Salt, chemicals, insects, tar, soot, tree sap,
and bird droppings should be washed off
by using a light detergent, as required. If
you use a light detergent, make certain
that it is a neutral detergent. Do not use
strong soap or chemical detergents. All
cleaning agents should be promptly rinsedoff the surface and not allowed to dry there.
Rinse the vehicle thoroughly with plenty of
lukewarm water. Wipe the remaining water
off with a chamois or soft cloth. Wear
rubber gloves and use a hand brush when
washing down underbody, inner fenders
and suspension to effectively remove mud
and dirt off.
!Washing the underbody
Chemicals, salts and gravel used for
deicing road surfaces are extremely cor-
rosive, accelerating the corrosion of un-
derbody components, such as the exhaust
system, fuel and brake lines, brake cables,
floor pan and fenders, and suspension.
Thoroughly flush the underbody and inside
of the fenders with lukewarm or cold water
at frequent intervals to reduce the harmful
effects of such agents.
Mud and sand adhering to the underbody
components may accelerate their corro-
sion.
After driving off-road or on muddy or sandy
roads, wash the mud and sand off the
underbody. Carefully flush the suspension
and axle parts, as they are particularly
prone to mud and sand buildup. Do not use
a sharp-edged tool to remove caked mud.

CAUTION
.Be careful not to damage brake
hoses, sensor harnesses, and
other parts when washing sus-
pension components.
.Be careful not to flush the engine
bottom for a long time. It may
cause damage of some electrical
parts.
!Using a warm water washer
.Keep a good distance of 12 in (30 cm)
or more between the washer nozzle and
the vehicle.
.Do not wash the same area continu-
ously.
.If a stain will not come out easily, wash
by hand. Some warm water washers are of
the high temperature, high pressure type,
and they can damage or deform the resin
parts such as moldings, or cause water to
leak into the vehicle.!Precautions for TYPE RA
!Precautions when cleaning the
carbon roof and rear wing
CAUTION
.When cleaning, take care that you
do not apply strong force to a
single point. Depending on the
degree of force and the location,
there is the risk of denting the
carbon roof or rear wing.
.After acid rain falls, it is recom-
mended that the vehicle be
washed before the water on the
paint evaporates.
.Promptly wash off any bird drop-
pings, insects, pollen, tree sap, or
similar substance that adheres to
the paint. If it is not promptly
washed off, it may penetrate the
paint.
.Remove any dirt using a neutral deter-
gent. Do not use hard brushes or abrasive
cleaners. Do not use strong or harsh
chemical cleaners.
.As the CFRP parts may change color if
they are exposed to ultraviolet rays for
extended periods of time, we recommend
that your vehicle be stored in a placewhere it will not be exposed to direct
sunlight.
.Do not use wax that contains abrasives.
NOTEDue to the characteristics of the carbon
roof, white cloudy areas may occur in
spots on the roof, however these do not
affect performance in any way.
!Precautions when cleaning
around the rear bumper cherry
red stripeRear bumper cherry red stripePrecautions when using a high-pres-
sure washer:
.Keep a distance of 12 in (30 cm) or
more between the washer nozzle and the
stripe.

.Do not continually wash the same
location.
.If using a high-temperature, high-pres-
sure washer, avoid cleaning the stripe.
Doing so may cause the stripe to peel off.
Precautions when using a solvent to
wash the car:
.Some solvents may adversely affect
seal adhesion performance. Be sure to
check the precautions listed on the solvent
before using it.
.If dirt is difficult to remove, a neutral
detergent diluted with water should be
used to carefully wipe off the dirt.&Waxing and polishingAlways wash and dry the vehicle before
waxing and polishing.
Use a good quality polish and wax and
apply them according to the manufac-
turer’s instructions. Wax or polish when
the painted surface is cool.
Be sure to polish and wax the chrome trim,
as well as the painted surfaces. Loss of
wax on a painted surface leads to loss of
the original luster and also quickens the
deterioration of the surface. It is recom-
mended that a coat of wax be applied at
least once a month, or whenever the
surface no longer repels water.If the appearance of the paint has dimin-
ished to the point where the luster or tone
cannot be restored, lightly polish the sur-
face with a fine-grained compound. Never
polish just the affected area, but include
the surrounding area as well. Always
polish in only one direction. A No. 2000
grain compound is recommended. Never
use a coarse-grained compound. Coarse-
grained compounds have a smaller grain-
size number and could damage the paint.
After polishing with a compound, coat with
wax to restore the original luster. Frequent
polishing with a compound or an incorrect
polishing technique will result in removing
the paint layer and exposing the under-
coat. When in doubt, it is always best to
contact your SUBARU dealer or an auto
paint specialist.
CAUTION
Do not use any agents with organic
solvents on the surface of the bulb
assembly cover. However, if a polish
or wax with organic solvents is
applied to the cover surface, com-
pletely wipe off the polish or wax.
Otherwise, the cover surface may be
damaged.
NOTEBe careful not to block the windshield
washer nozzles with wax when waxing
the vehicle.&Cleaning alloy wheels.Promptly wipe the alloy wheels clean of
any kind of grime or agent. If dirt is left on
too long, it may be difficult to clean off.
.Do not use soap containing grit to clean
the wheels. Be sure to use a neutral
cleaning agent, and later rinse thoroughly
with water. Do not clean the wheels with a
stiff brush or expose them to a high-speed
washing device.
.Clean the vehicle (including the alloy
wheels) with water as soon as possible
when it has been splashed with sea water,
exposed to sea breezes, or driven on
roads treated with salt or other agents.

Cleaning the interiorUse a soft, damp cloth to clean the climate
control panel, audio equipment, instru-
ment panel, center console, combination
meter panel, and switches. (Do not use
organic solvents.)&Seat fabricRemove loose dirt, dust or debris with a
vacuum cleaner. If the dirt is caked on the
fabric or hard to remove with a vacuum
cleaner, use a soft brush then vacuum it.
Wipe the fabric surface with a tightly wrung
cloth and dry the seat fabric thoroughly. If
the fabric is still dirty, wipe using a solution
of mild soap and lukewarm water then dry
thoroughly.
If the stain does not come out, try a
commercially-available fabric cleaner.
Use the cleaner on a hidden place and
make sure it does not affect the fabric
adversely. Use the cleaner according to its
instructions.
CAUTION
When cleaning the seat, do not use
benzine, paint thinner, or any similar
materials. Doing so could damage
the surface and cause the color todeteriorate.
&Leather seat materialsThe leather used by SUBARU is a high
quality natural product which will retain its
distinctive appearance and feel for many
years with proper care.
Allowing dust or road dirt to build up on the
surface can cause the material to become
brittle and to wear prematurely. Regular
cleaning with a soft, moist, natural fiber
cloth should be performed monthly, taking
care not to soak the leather or allow water
to penetrate the stitched seams.
A mild detergent suitable for cleaning
woolen fabrics may be used to remove
difficult dirt spots, rubbing with a soft, dry
cloth afterwards to restore the luster. If
your SUBARU is to be parked for a long
time in bright sunlight, it is recommended
that the seats and head restraints be
covered, or the windows shaded, to pre-
vent fading or shrinkage. Make sure to
remove any seat covers and head restraint
covers when operating the vehicle.
Minor surface blemishes or bald patches
may be treated with a commercial leather
spray lacquer. You will discover that each
leather seat section will develop soft folds
or wrinkles, which is characteristic of
genuine leather.
&Synthetic leather upholsteryThe synthetic leather material used on the
SUBARU may be cleaned using mild soap
or detergent and water, after first vacuum-
ing or brushing away loose dirt. Allow the
soap to soak in for a few minutes and wipe
off with a clean, damp cloth. Commercial
foam-type cleaners suitable for synthetic
leather materials may be used when
necessary.
CAUTION
Strong cleaning agents such as
solvents, paint thinners, window
cleaner or fuel must never be used
on leather or synthetic interior ma-
terials. Doing so could damage the
surface and cause the color to
deteriorate.

Check the fluid level on the outside of the
reservoir. Because this reservoir is used
for both the brake and clutch systems and
has chambers for each system, be sure to
check the fluid level for the clutch system
at theinboard side of the reservoir
(shaded area in the illustration). If the fluid
level is below“MIN”, add the recom-
mended clutch fluid to“MAX”.
Use only clutch fluid from a sealed contain-
er.&Recommended clutch fluidRefer to“Fluids”F12-7.
CAUTION
Never use different brands of clutch
fluid together. Also, avoid mixing
DOT 3 and DOT 4 brake fluids even if
they are the same brand.
Brake boosterIf the brake booster does not operate as
described in the following, have it checked
by your SUBARU dealer.
1. With the engine off, depress the brake
pedal several times, applying the same
pedal force each time. The distance the
pedal travels should not vary.
2. With the brake pedal depressed, start
the engine. The pedal should move slightly
down to the floor.
3. With the brake pedal depressed, stop
the engine and keep the pedal depressed
for 30 seconds. The pedal height should
not change.
4. Start the engine again and run for
approximately one minute then turn it off.
Depress the brake pedal several times to
check the brake booster. The brake
booster operates properly if the pedal
stroke decreases with each depression.NOTEWhen you depress the brake pedal
strongly or suddenly, you might feel
that lighter depression of the brake
pedal generates a greater braking
force. However, even though these
occur, they do not indicate any mal-
functions, and the brake assist systemis operating properly.
Brake assist is not a system that brings
more braking ability to the vehicle
beyond its breaking capability.
