body is cool.
276
4-1. Maintenance and care
■ Automatic car washes
● Fold the mirrors before washing the vehicle. Start washing from the front
of the vehicle. Make sure to and extend the mirrors before driving.
● When having your vehicle washed in an automatic car wash, make sure
beforehand that the car wash is of suitable type to avoid scratches to the
vehicle surface and harm to your vehicle’s paint.
● Vehicles with a rear spoiler: In certain automatic car washes, the rear
spoiler may interfere with machine operation. This may prevent the vehicle from being cleaned properly or result in damage to the rear spoiler.
■ High pressure car washes
● Do not allow the nozzles of the car wash to come within close proximity
of the windows and door frames as water may enter the cabin.
● Before car wash, check that the fuel filler lid on your vehicle is closed
properly.
■ Aluminum wheels (if equipped)
● Remove any dirt immediately by using a neutral detergent. Do not use
hard brushes or abrasive cleaners. Do not use strong or harsh chemical
cleaners. Use the same mild detergent and wax as used on the paint.
● Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
● Wash detergent from the wheels immediately after use.
■ Parts containing resin such as the bumper
Do not scrub with abrasive cleaners.

4-1. Maintenance and care
WARNING
■ When washing the vehicle
● Do not wash the engine compartment and area adjacent to it. If water
enters the engine air intake or electrical parts it will cause engine trouble or
a malfunction of the power steering.
● 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 pedal to heat up the brakes.
■ Precautions regarding the exhaust pipes
Exhaust gasses cause the exhaust pipes and rear bumper diffusers to
become quite hot.
When washing the vehicle, be careful not to touch the pipes and diffusers
until they have cooled sufficiently, as touching hot exhaust pipes and rear
bumper diffusers can cause burns.
CAUTION
■ To prevent paint deterioration and corrosion on the body and compo-
nents (aluminum wheels etc.)
● Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If you see coal tar or tree sap on the paint surface
• If you see dead insects, insect droppings or bird droppings on the paint
• After driving in an area contaminated with soot, oily smoke, mine dust,
iron powder or chemical substances
• If the vehicle becomes heavily soiled in dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
● If the paint is chipped or scratched, have it repaired immediately.
● To prevent the wheels from corroding, remove any dirt and store in a place
with low humidity when storing the wheels.
■ Protective film for side sill plates
Make sure to remove the protective film. Failure to do so may cause rust,
depending on conditions.

280
4-1. Maintenance and care
■ Caring for leather areas
SUBARU recommends cleaning the interior of the vehicle at least twice a
year to maintain the quality of the vehicle’s interior.
■ Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a
sponge or brush to apply the foam. Rub in overlapping circles. Do not apply
water. Excellent results are obtained by keeping the carpet as dry as possible.
■ Seatbelts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
WARNING
■ Water in the vehicle
● Do not splash or spill liquid in the vehicle.
Doing so may cause electrical components etc. to malfunction or catch
fire.
● Do not get any of the SRS components or wiring in the vehicle interior wet.
(→P. 93)
Electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or severe injury.
■ Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off
the windshield, obstructing the driver's view and leading to an accident,
resulting in death or serious injury.

4-1. Maintenance and care
CAUTION
■ Cleaning detergents
● Do not use organic substances such as benzene or gasoline, acidic or
alkaline solutions, dye, bleach or other detergent. Doing so may discolor
the vehicle interior or cause streaks or damage to painted surfaces.
● Do not use polish wax or polish cleaner. The instrument panel's or other
interior part’s painted surface may be damaged.
● Do not use a chemical agent containing silicone (highly-polymerized sili-
con compound) when cleaning any of the electrical appliances such as the
air conditioning, all switches and their surrounding areas.
If silicon (highly-polymerized silicon compound) contacts these components, it may cause the electrical appliances to malfunction.
■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces.
● Remove any dust, dirt, sand, oil spots etc. on leather surfaces immedi-
ately.
● Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl, plastic, or that contain wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
■ Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components under the floor of the vehicle, and
may also cause the body to rust.

Maintenance requirements
To ensure safe and economical driving, day-to-day care and regular
maintenance is essential. It is the owner’s responsibility to perform
regular checks. SUBARU recommends the following maintenance.
■ General maintenance
Should be performed on a daily basis. This can be done by yourself or by a SUBARU dealer.
■ Scheduled maintenance
Should be performed at specified intervals according to the
maintenance schedule.
For details about maintenance items and schedules, refer to the “Warranty and Maintenance Booklet”.
■ Do-it-yourself maintenance
You can perform some maintenance procedures yourself.
Please be aware that do-it-yourself maintenance may affect warranty coverage.

WARNING
■ If your vehicle is not properly maintained
It could result in serious damage to the vehicle and possible serious injury or
death.
■ Warning in handling of battery
● Before beginning work on or near any battery, be sure to extinguish all cig-
arettes, matches, and lighters. 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 working near any battery. Never lean over a battery.
● Do not let battery fluid contact eyes, skin, fabrics, or paint because battery
fluid is a corrosive acid. If battery fluid gets on your skin or in your eyes,
immediately flush the area with water thoroughly. Seek medical help
immediately if acid has entered the eyes.
If battery fluid is accidentally swallowed, immediately drink a large amount
of milk or water, and seek medical attention immediately.
● To lessen the risk of sparks, remove rings, metal watchbands, and other
metal jewelry. Never allow metal tools to contact the positive battery terminal and anything connected to it WHILE you are at the same time in contact with any other metallic portion of the vehicle because a short circuit
will result.
● Keep everyone including children away from the battery.
● Charge the battery in a wellventilated area.
● Battery posts, terminals and related 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 cancer. Wash hands after handling.
