Maintenance and care
Engine oil
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
■Checking the engine oil
Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than five minutes for the oil to
drain back into the bottom of the engine.
Hold a rag under the end and
pull the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully.
Holding a rag under the end, pull the dipstick out and check
the oil level.
When checking the oil, look at both sides of the dipstick and use the
lower measurement to determine the level of oil.
Wipe the dipstick and reinsert it fully.

■Adding engine oil
If the oil level is below or near
the low level mark, add engine
oil of the same type as already in
the engine.
Make sure to check the oil type and prepare the items needed before
adding oil.
Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise.

■Engine oil consumption
Some engine oil will be consumed while driving. Under the following condi-
tions, oil consumption can be increased and thus require refilling between
maintenance intervals:
●When the engine is new and within the break-in period
●When the engine oil is of lower quality
●When the incorrect oil viscosity is used
●When engine braking is employed

Maintenance and care
●When the engine is operated at high engine speeds
●When the engine is operated under heavy loads
●When towing a trailer
●When the engine idles for long periods of time
●When the vehicle is operated in stop and go and/or heavy traffic situa-
tions
●When the vehicle is used under severe thermal conditions
●When the vehicle accelerates and decelerates frequently
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 every 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
not dispose of used oil and filters in household trash, in sewers or onto the
ground.
Call your SUBARU dealer, service station or auto parts store for informa-
tion concerning recycling or disposal.
●Do not leave used engine oil within the reach of children.

Engine coolant
The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the engine is cold.
Reservoir cap
“FULL”
“LOW”
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line.
CAUTION
■To prevent serious engine damage
Check the oil level on a regular basis.
■When replacing the engine oil
●Be careful not to spill engine oil on the vehicle components.
●Avoid overfilling, or the engine could be damaged.
●Check the oil level on the dipstick every time you fill the oil.
●Be sure the engine oil filler cap is properly tightened.
■If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, engine coolant filler cap, radiator cap,
drain cock and water pump.
If you cannot find a leak, have your SUBARU dealer pressure test the cap
and check for leaks in the cooling system.

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: -31qF [-35qC])
For more details about engine coolant, 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 straight 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.

304 4-3. Do-it-yourself maintenance
Radiator and condenser
Check the radiator and condenser and clear any foreign objects.
If either of the above parts are extremely dirty or you are not sure of
their condition, have your vehicle checked by your SUBARU dealer.
Brake fluid
■Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.
“MAX”
“MIN”
WARNING
■When the engine is hot
Do not touch the radiator or condenser as they may be hot and cause seri-
ous injuries, such as burns.

Maintenance and care
■Adding fluid
Make sure to check the fluid type and prepare the necessary items.
Fluid type
FMVSS No.116 fresh DOT 3 or DOT 4 brake fluid
Items
Clean 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.

Battery
Check the battery as follows.
■Battery exterior
Make sure that the battery terminals are not corroded and that
there are no loose connections, cracks, or loose clamps.
Hold-down clamp
Te r m i n a l s
■Checking battery fluid
Check that the level is between
“UPPER LEVEL” and “LOWER
LEVEL”.
“UPPER LEVEL”
“LOWER LEVEL”
If the fluid level is at or below
“LOWER LEVEL”, add distilled
water.

Maintenance and care
■Adding distilled water
Remove the vent plug.
Add distilled water.
If the “UPPER LEVEL” line cannot be seen, check the fluid level by
looking directly at the cell.
Put the vent plug back on and close securely.
