2. Place a proper container under the drain plug and
loosen the drain plug.
Never attempt to remove the radiator cap until
the engine has been shut off and has cooled
down completely. Since the coolant is under
pressure, you may suffer serious burns from a
spray of boiling hot coolant when the cap is re-
moved. 3. Loosen the radiator cap to drain the coolant from
the radiator. Then drain the coolant from the reserve
tank. Tighten the drain plug securely.
NOTE (Turbo models)
The cap (without tabs) on top of the radiator does
not need to be removed. To add coolant, remove
the cap (with tabs) on the coolant tank on top of
the engine.

1) Filler neck
2) Fill up to here
4. Slowly pour the coolant and fill up to just below the
filler neck, allowing enough room to add genuine
SUBARU cooling system conditioner in the radiator.
Add genuine SUBARU cooling system conditioner un-
til the coolant level reaches the filler neck. Do not pour
the coolant too quickly, as this may lead to insufficient
air bleeding and trapped air in the system.
Coolant capacity (Guideline): Non-turbo models: MT. 7.2 US qt (6.8 liters, 6.0 Imp qt)
AT. 7.1 US qt (6.7 liters, 5.9 Imp qt)
Turbo models: MT. 8.1 US qt (7.7 liters, 6.8 Imp qt)
AT. 8.0 US qt (7.6 liters, 6.7 Imp qt)
yBe careful not to spill engine coolant when
adding it. If coolant touches the exhaust pipe, it
may cause a bad smell, smoke, and/or a fire. y Do not splash the engine coolant over paint-
ed parts. The alcohol contained in the engine
coolant may damage the paint surface.

5. Pour the coolant and fill to the reservoir tank’s
“FULL” level mark. 1) Rubber gaskets
6. Put the radiator cap back on and tighten firmly. At
this time, make sure that the rubber gasket in the radi-
ator cap is correctly in place.
7. Start and run the engine for more than five minutes
at 2,000 to 3,000 rpm.
8. Stop the engine and wait until the coolant cools
down (122 to 140 °F [50 to 60 °C]). If there is any loss
of coolant, add coolant to the radiator’s filler neck and
to the reserve tank’s “FULL” level.
9. Put the radiator cap and reservoir cap back on and
tighten firmly.

Air cleaner element
Do not operate the engine with the air cleaner
element removed. The air cleaner element not
only filters intake air but also stops flames if the
engine backfires. If the air cleaner element is
not installed when the engine backfires, you
could be burned.
The air cleaner element functions as a filter screen.
When the element is perforated or removed, engine
wear will be excessive and engine life shortened.
The air cleaner element is a viscous type. It is unnec-
essary to clean or wash the element. „ Replacing the air cleaner element
T Non-turbo models
Replace the air cleaner element according to the
maintenance schedule in the “Warranty and Mainte-
nance Booklet”. Under extremely dusty conditions, re-
place it more frequently. It is recommended that you
always use genuine SUBARU parts.

Automatic transmission fluid „Checking the fluid level
The automatic transmission fluid expands largely as
its temperature rises; the fluid level differs according to
fluid temperature. Therefore, there are two different
scales for checking the level of hot fluid and cold fluid
on the dipstick.
Though the fluid level can be checked without warm-
ing up the fluid on the “COLD” range, we recommend
checking the fluid level when the fluid is at operating
temperature. T Checking the fluid level when the fluid is hot
Check the fluid level monthly.
1. Drive the vehicle several miles to raise the temper-
ature of the transmission fluid up to normal operating
temperature; 158 to 176 °F (70 to 80 °C) is normal.
2. Park the vehicle on a level surface and set the park-
ing brake.
3. First shift the selector lever in each position. Then
shift it in the “P” position, and run the engine at idling
speed.-30 -20 -10 0 10 20 30 40

Brake booster
If the brake booster does not operate as described be-
low, have it checked by your SUBARU dealer.
1. With the engine off, depress the brake pedal sever-
al 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 about one minute
then turn it off. Depress the brake pedal several times
to check the brake booster. Brake booster operates
properly if the pedal stroke decreases with each de-pression.Brake pedal
Check the brake pedal free play and reserve distance
according to the maintenance schedule in the “War-
ranty and Maintenance Booklet”. „Checking the brake pedal free play
1) 0.04 – 0.12 in (1.0 – 3.0 mm)
Stop the engine and firmly depress the brake pedal
several times. Lightly press the brake pedal down with
one finger to check the free play with a force of less
than 2 lbs (10 N, 1 kg).
If the free play is not within proper specification, con-

Checking the brake pedal reserve dis-
tance
1) More than 2.56 in (65 mm)
Depress the pedal with a force of approximately 66 lbs
(294 N, 30 kg) and measure the distance between the
upper surface of the pedal pad and the floor.
When the measurement is smaller than the specifica-
tion, or when the pedal does not operate smoothly,
contact with your SUBARU dealer. Clutch pedal (Manual transmission
vehicles)
Check the clutch pedal free play and reserve distance
according to the maintenance schedule in the “War-
ranty and Maintenance Booklet”. „
Checking the clutch function
Check the clutch engagement and disengagement.
1. With the engine idling, check that there are no ab-
normal noises when the clutch pedal is depressed,
and that shifting into 1st or reverse feels smooth.
2. Start the vehicle by releasing the pedal slowly to
check that the engine and transmission smoothly cou-
ple without any sign of slippage.

Aluminum wheels
Aluminum wheels can be scratched and damaged
easily. Handle them carefully to maintain their appear-
ance, performance, and safety. y
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.y Never apply oil to the threaded parts, wheel nuts, or
tapered surface of the wheel.y Never let the wheel rub against sharp protrusions or
curbs. y Be sure to fit tire chains on uniformly and completely
around the tire, otherwise the chains may scratch the
wheel.y 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
Never use engine coolant as washer fluid be-
cause it could cause paint damage.
Check the level of the washer fluid at each fuel stop. If
the level is low, fill the fluid up to the neck of the reser- voir.
Use windshield washer fluid. If windshield washer fluid
is unavailable use clean water.
In areas where water freezes in winter, use an anti-
