11-14Maintenance and service
Refer to“Fuses ”F 11-45 and “Fuse panel
located in the engine compartment ”F 12-
13.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
the cooling system and connections be
checked for leaks, damage, or looseness.
& Engine coolant
! Checking the coolant level
1) “FULL ”level mark
2) “LOW ”level mark
Check the coolant level at each fuel stop.
1. Check the coolant level on the outside
of the reservoir while the engine is cool.
2. If the level is close to or lower than the “
LOW ”level mark, add coolant up to the
“ FULL ”level mark. If the reserve tank is
empty, remove the radiator cap and refill
as required.
3. After refilling the reserve tank and the
radiator, reinstall the caps and check that
the rubber gaskets inside the radiator cap
are in the proper position.
CAUTION
. Be 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. If engine coolant gets on
the exhaust pipe, be sure to wipe
it off.
. Do not splash the engine coolant over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
! Changing the coolant
WARNING
Never attempt to remove the radia-
tor 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 boil-
ing hot coolant when the cap isremoved.
Always add genuine SUBARU cooling
system conditioner whenever the coolant
is replaced.
Change the engine coolant and add
genuine SUBARU cooling system condi-
tioner using the following procedures
according to the maintenance schedule.
1. Remove the under cover.

2. Place a proper container under the
drain plug and loosen the drain plug.
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 only)
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 theengine.
4. Install the under cover.Non-turbo models
1) Fill up to this level
Turbo models
1) Fill up to this level
5. 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 condi-
tioner until 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. NOTE
For guidelines on coolant quantity
(including the coolant in resorvoir
tank), refer to
“Engine coolant ”F 12-9.

WARNING
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.
CAUTION
When replacing the air cleaner ele-
ment, use a genuine SUBARU air
cleaner element. If it is not used,
there is the possibility of causing a
negative effect to the engine.
The air cleaner element functions as a
filter screen. When the element is perfo-
rated or removed, engine wear will be
excessive and engine life shortened.
It is not necessary to clean or wash the element.

&Replacing the air cleaner element
Replace the air cleaner element according
to the maintenance schedule in the“ Warranty and Maintenance Booklet ”. Un-
der extremely dusty conditions, replace it
more frequently. It is recommended that
you always use genuine SUBARU parts. ! Non-turbo models

Check the oil level monthly.
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the level gauge, wipe it clean,
and insert it again.
1) Upper level
2) Lower level
3. Pull out the level gauge again and
check the oil level on it. If it is below the
lower level, add oil through the level
gauge hole to bring the level up to the
upper level.
CAUTION
Be careful not to spill manual trans-
mission oil when adding it. If oil
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or a
fire. If oil gets on the exhaust pipe,
be sure to wipe it off.

&Recommended grade and viscosity
Each oil manufacturer has its own base
oils and additives. Never use different
brands together. For details, refer to“ Manual transmission, front differential
and rear differential gear oil ”F 12-8. 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 level gauge.
Though the fluid level can be checked
without warming up the fluid on the“ COLD ”range, it is recommended to
check the fluid level when the fluid is at
operating temperature. ! Checking the fluid level when the
fluid is hot
1. Drive the vehicle several miles to raise
the temperature of the transmission fluid
up to normal operating temperature; 158
to 176 8F (70 to 80 8C) is normal.
2. Park the vehicle on a level surface and
set the parking brake.
3. First shift the select lever in each
position. Then shift it in the “P ” position,
and run the engine at idling speed.

fluid level on the gauge. If it is below the
lower level on the “HOT ”range, add the
recommended automatic transmission
fluid up to the upper level. ! Checking the fluid level when the
fluid is cold
When the fluid level has to be checked
without time to warm up the automatic
transmission, check to see that the fluid
level is between the lower level and upper
level on the “COLD ”range. If it is below
that range, add fluid up to the upper level.
Be careful not to overfill.
CAUTION
Be careful not to spill automatic
transmission fluid when adding it.
If automatic transmission fluid
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or a
fire. If automatic transmission fluid
gets on the exhaust pipe, be sure to
wipe it off. &
Recommended fluid
Refer to “Fluids ”F 12-9.
NOTE
Using any non-specified type of auto-
matic transmission fluid could result in
damage inside the transmission. When
replacing the automatic transmission
fluid, be sure to use the kind specified. Front differential gear oil (AT
