WARNING
■Pre-driving check
Check that the engine hood is fully closed and locked.
If the engine hood is not locked properly it may open while the vehicle is in
motion and cause an accident, which may result in death or serious injury.
CAUTION
■When opening the engine hood
●Do not lift up or operate the wipers. Doing so may cause the engine hood
and wipers to contact, scratching the engine hood.
●Use caution when opening the engine hood in windy weather as it may
close suddenly in strong wind.
●Do not attach any accessories other than genuine SUBARU products to
the engine hood. Such additional weight on the engine hood may cause it
to be too heavy to be supported by the supporting rod when opened.
■When closing the engine hood
Do not apply excessive weight or force when closing the engine hood as
doing so may result in damage.

Under these or similar conditions, you should check your oil at least every
2nd fuel fill-up and change your engine oil more frequently. If your oil con-
sumption rate is greater than 1 quart ev ery 1,200 miles or 1 liter every 2,000
kilometers, contact your SUBARU dealer who may perform a test under con-
trolled conditions.
WARNING
■Used engine oil
●Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation or skin cancer, so care should
be taken to avoid prolonged and repeated contact. To remove used engine
oil from your skin, wash thoroughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner. Do

Maintenance and care
■Coolant selection
Only use SUBARU Super Coolant or similar high-quality ethylene glycol-
based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-
life hybrid organic acid technology.
SUBARU Super Coolant is a mixture of 50% coolant and 50% deionized
water. (Enabled: -31°F [-35 °C])
For more details about engine cool ant, contact your SUBARU dealer.
WARNING
■When the engine is hot
Do not remove the radiator cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
CAUTION
■When adding engine coolant
Coolant is neither plain water nor stra ight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to prevent it damaging parts or paint.

Maintenance and care
■Adding fluid
Make sure to check the fluid type and prepare the necessary items.
Fluid typeFMVSS No.116 fresh DOT 3 or DOT 4 brake fluid
ItemsClean funnel
■Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
WARNING
■When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets in your eyes, flush your eyes with clean water immediately.
If you still experience discomfort, see a doctor.
CAUTION
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

WARNING
■Chemicals in the battery
A battery contains poisonous and corrosive sulfuric acid and may produce
hydrogen gas which is flammable and explosive. To reduce the risk of death
or serious injury, take the following precautions while working on or near the
battery:
●Do not cause sparks by touching the battery terminals with tools.
●Do not smoke or light a match near the battery.
●Avoid contact with eyes, skin and clothes.
●Never inhale or swallow electrolyte.
●Wear protective safety glasses when working near the battery.
●Keep children away from the battery.
■Where to safely charge the battery
Always charge the battery in an open area. Do not charge the battery in a
garage or closed room where there is not sufficient ventilation.
■Emergency measures regarding electrolyte
●If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immedi-
ate medical attention. If possible, continue to apply water with a sponge or
cloth while traveling to the nearest medical facility.

Tires
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.
■Checking tiresNew tread
Treadwear indicator
Worn tread
The location of treadwear
indicators is shown by the
“TWI” or “ ” marks, etc.,
molded on the sidewall of
each tire.
Check spare tire condition
and pressure if not rotated.
■Tire rotationRotate the tires in the order
shown.
To equalize tire wear and
extend tire life, SUBARU rec-
ommends that tire rotation is
carried out at the same inter-
val as tire inspection.
■The tire pressure monitoring system (if equipped)
Your SUBARU is equipped with a tire pressure monitoring sys-
tem that uses tire pressure warning valves and transmitters to
detect low tire inflation pressure before serious problems arise. (→ P. 373)

Maintenance and care
Installing tire pressure warning valves and transmitters (vehicles
with a tire pressure monitoring system)When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new tire pressure warning valve and transmitter ID codes
must be registered in the tire pressure warning computer and tire
pressure monitoring system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by your SUBARU
dealer. ( →P. 314)

4-3. Do-it-yourself maintenance
Registering ID codes (vehicles with a tire pressure monitoring
system)
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your SUBARU dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consult with your SUBARU dealer.
■Replacing tires and wheels (vehicles with a tire pressure monitor-
ing system)
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pressure monitoring system will not work properly.
After driving for about 20 minutes, the tire pressure warning light comes
on after blinking for 1 minute to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if they have seldom or never been used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Low profile tires (vehicles with 17-inch tires)
Generally, low profile tires will wear more rapidly and tire grip perfor-
mance will be reduced on snowy and/or icy roads when compared to
standard tires. Be sure to use snow tires or tire chains on snowy and/or
icy roads and drive carefully at a speed appropriate for road and weather
conditions.
