Instruments and controls/Warning and indicator lights
After that, this indicator light/warning light
changes toBLUEand maintains illumina-
tion in BLUE. This BLUEilluminated light
turns off when the engine is warmed up
sufficiently.
If the engine coolant temperature in-
creases over the specified range, the
indicator light/warning light blinks in
RED . At this time, the engine is close to
overheating.
If the engine coolant temperature in-
creases further, the indicator light/warning
light illuminates in REDcontinuously. At
this time, the engine may be overheating.
When the indicator light/warning light
blinks in REDor illuminates in RED, safely
stop the vehicle as soon as possible, and
refer to the emergency steps to take in the
case of engine overheating. Refer to
“Engine overheating ”F 9-13. After that,
have the system checked by your nearest
SUBARU dealer.
Also, if the indicator light/warning light
often blinks in RED, the electrical system
may be malfunctioning. Contact your
SUBARU dealer for an inspection.
NOTE
If the engine is restarted after a certain
driving condition, this indicator light/ warning light may illuminate in RED.
However, this is not a malfunction if the
indicator light/warning light turns off
after a short time.
&Charge warning light
If this light illuminates when the engine is
running, it may indicate that the charging
system is not working properly.
If the light illuminates while driving or does
not turn off after the engine starts, stop the
engine at the first safe opportunity and
check the alternator belt. If the belt is
loose, broken or if the belt is in good
condition but the light remains illuminated,
contact your nearest SUBARU dealer
immediately.
&Oil pressure warning
light
If this light illuminates when the engine is
running, it may indicate that the engine oil
pressure is low and the lubricating system
is not working properly.
If the light illuminates while driving or does
not turn off after the engine starts, stop the
engine at the first safe opportunity and
check the engine oil level. If the oil level is
low, add oil immediately. If the engine oil is
at the proper level but the light remainsilluminated, contact your nearest
SUBARU dealer immediately.
For details about checking the engine oil
level or adding the engine oil, refer to
“Engine oil
”F 11-8.
CAUTION
Do not operate the engine with the
oil pressure warning light illumi-
nated. This may cause serious en-
gine damage.
&Engine low oil level
warning light
This light illuminates when the engine oil
level decreases to the lower limit.
If the engine low oil level warning light
illuminates while driving, park the vehicle
in a safe and level location, and then
check the engine oil level. When the
engine oil level is not within the normal
range, refill with engine oil. Refer to
“Engine oil ”F 11-8.
If the warning light does not turn off after
refilling the engine oil, or the warning light
illuminates even though the engine oil
level is within the normal range, have the
vehicle checked by a SUBARU dealer.

CAUTION
Trapping small animals in the cool-
ing fan and belts of the engine may
result in a malfunction. Check that
no small animal enters the engine
compartment and under the vehicle
before starting the engine.
NOTE
Engine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.
Starting and stopping the
engine (models without
push-button start system)
CAUTION
Do not operate the starter motor
continuously for more than 10 sec-
onds. If the engine fails to start after
operating the starter for 5 to 10
seconds, wait for 10 seconds or
more before trying again.
NOTE
It may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This diffi-
culty is caused by the electronically
controlled throttle’s self-diagnosis
function. To overcome it, keep the
ignition switch in the “ON”position
for approximately 10 seconds before
starting the engine.
& Starting engine
! General precautions when starting
engine
WARNING
.Never start the engine from out-
side the vehicle (except when
using the remote engine start
system). It may result in an
accident.
. Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide poi-
soning.
. Do not start the engine near dry
foliage, paper, or other flam-
mable substances. The exhaust
pipe and exhaust emissions can
create a fire hazard at high
temperatures.
CAUTION
. If the engine is stopped during
driving, the catalyst may over-
heat and burn.
Starting and operating/Starting and stopping the engine (models without push –button start system)

Engine overheating
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has fully cooled down.
When the engine is hot, the coolant
is under pressure. Removing the
cap while the engine is still hot
could release a spray of boiling hot
coolant, which could burn you very
seriously.
If the engine overheats, safely pull off the
road and stop the vehicle in a safe
location.
& If steam is coming from the
engine compartment
. Turn the ignition switch to the “LOCK”/
“OFF ”position and get everyone away
from the vehicle until it cools down.
. Contact an authorized SUBARU deal-
er.
& If no steam is coming from
the engine compartment
1. Keep the engine running at idling
speed. 2. Open the engine hood to ventilate the
engine compartment. Refer to
“Engine
hood ”F 11-5.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact an authorized
SUBARU dealer for repair.
3. After the coolant temperature high
warning light that has blinked or illumi-
nated in REDturns off, turn off the engine.
For details about the warning light, refer to
“Coolant temperature low indicator light/
Coolant temperature high warning light ”
F 3-17.
4. After the engine has fully cooled down,
check the coolant level in the reserve
tank. If the coolant level is below the
“LOW ”mark, add coolant up to the “FULL ”
mark.
NOTE
For details about how to check the
coolant level or how to add coolant,
refer to “Engine coolant ”F 11-11.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank.
Then remove the radiator cap and fill the
radiator with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the
radiator cap, then turn the cap counter- clockwise slowly without pressing down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.

diluted with another brand or
type, the maintenance interval is
shortened to that of the mixing
coolant.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
& Cooling fan, hose and con-
nections
Your vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the coolant temperature high
warning light blinks or illuminates in RED,
the cooling fan circuit may be defective.
Refer to “Coolant temperature low indica-
tor light/Coolant temperature high warning
light ”F 3-17.
Check the fuse and replace it if necessary.
Refer to “Fuses”F 11-35 and “Fuse panel
located in the engine compartment ”F 12-
12.
If the fuse is not blown, have the cooling
system checked by your SUBARU dealer.
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
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 is
removed.
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
coolant up to just below the filler neck as
shown in the following illustration.
Maintenance and service/Cooling system
–CONTINUED –11-11

Maintenance and service/Air cleaner element
1) Fill up to this level
3. After refilling the reserve tank and the
radiator, reinstall the cap 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
It may be difficult to change the coolant.
Have the coolant changed by your
SUBARU dealer if necessary.
The coolant should be changed according
to the maintenance schedule in the
“Warranty and Maintenance Booklet ”.
Air cleaner element
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 air
cleaner element.
