This coolant temperature low indicator
light/coolant temper ature high warning
light has the following three functions.
 Illumination in BLUE indicates insuffi-
cient warming up of the engine
 Blinking in RED indicates that the
engine is close to overheating
 Illumination in RED indicates over-
heating condition of the engine
For the system check, this indicator light/
warning light illuminates in RED for
approximately 2 seconds when the igni-
tion switch is turned to the “ON” position.
After that, this indicator light/warning light
changes to BLUE and maintains illumina- tion in
BLUE. This BLUE illuminated light
turns off when the engine is warmed up
sufficiently.
If the engine coolant temperature
increases over the specified range, the
indicator light/warning light blinks in RED.
At this time, the engine is close to over-
heating.
If the engine coolant temperature
increases further, the indicator light/
warning light illuminates in RED continu-
ously. At this time, the engine may be
overheating.
When the indicator light/warning light
blinks in RED or illuminates in RED, safely
stop the vehicle as soon as possible, and
refer to the emergency steps for the
engine overheating. Refer to "Engine
Overheating" P319. 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.
NOTEIf 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 LightIf 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 drive 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 immedi-
ately.■ Oil Pressure Warning
LightIf 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
- Blinking or illuminated in
RED: 
Safely stop the vehicle as
soon as possible, and refer to
the emergency steps for the
engine overheating. After that,
have the system checked by
your nearest SUBARU dealer.
Refer to "Engine Overheating"
 P319- Blinking in RED and BLUE
alternately: 
The electrical system may be
malfunctioning. Contact your
SUBARU dealer for an inspec-
tion.
CAUTION
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.

Warning and Indicator Lights
138engine at the first safe opportunity and
contact your nearest SUBARU dealer
immediately.■ AT OIL TEMP Warning
Light (AT Models) If this light illuminates when the engine is
running, it may indicate that the transmis-
sion fluid temperature is too hot.
If the light illuminates while driving, imme-
diately stop the vehicle in a safe place and
let the engine idle until the warning light
turns off.■ Low Tire Pressure
Warning Light (If
Equipped)When the ignition switch is turned to the
“ON” position, the low tire pressure
warning light will illuminate for approxi-
mately 2 seconds to check that the tire
pressure monitoring system (TPMS) is
functioning properly. If there is no problem
and all tires are properly inflated, the light
will go out.
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on the vehicle placard or tire inflation pres-
sure label, you should determine the

proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illumi-
nates a low tire pressure telltale when one
or more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TP MS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain
correct tire pressure, even if under-infla-
tion has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is no t operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure tell-
tale. When the system detects a malfunc-
tion, the telltale will flash for approximately one minute and then remain continuously

illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the
malfunction indicator is illuminated, the
system may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of
replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS
to continue to function properly.
Should the warning light illuminate
steadily after blinking for approximately
one minute, have the system inspected by
your nearest SUBARU dealer as soon as
possible.
WARNING
If this light does not illuminate
briefly after the ig nition switch is
turned on or the light illuminates
steadily after blinking for approxi-
mately one minute, you should have
your Tire Pressure Monitoring Sys-
tem checked at a SUBARU dealer as
soon as possible.

vated.
4-6. Operating Tips for Heater and Air Conditioner■ Cleaning Ventilator Grille1) Front ventilator inlet grille
2) CondenserAlways keep the front ventilator inlet grille
free of snow, leaves, or other obstructions
to ensure efficient heating and defrosting.
Since the condenser is located in front of
the radiator, this area should be kept
clean because cooling performance is
impaired by any accu mulation of insects
and leaves on the condenser.
■ Efficient Cooling after
Parking in Direct SunlightAfter parking in direct sunlight, drive with
the windows open for a few minutes to
allow outside air to circulate into the
heated interior. This results in quicker
cooling by the air conditioner. Keep the
windows closed during the operation of
the air conditioner for maximum cooling
efficiency.■ Lubrication Oil Circulation in
the Refrigerant CircuitOperate the air conditioner compressor at
a low engine speed (at idle or low driving
speeds) a few minutes each month during
the off-season to circulate its oil.■ Checking Air Conditioning
System before Summer
SeasonCheck the air conditioner unit for refrig-
erant leaks, hose conditions, and proper
operation each spring. Have the air condi-
tioning system checked by your SUBARU
dealer.

NOTEEngine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.
7-4. Starting and Stopping Engine■Safety PrecautionsRefer to "Safety Precautions"  P94.■Operating Range for Push-
Button Start SystemRefer to "Operating Range for Push-
Button Start System" P125.■ General Precautions When
Starting Engine
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
difficulty is caused by the electroni-
cally controlled throttle’s self-diag-
nosis function. To overcome it, keep
the ignition switch in the “ON” position
for approximately 10 seconds before
starting the engine.
 Avoid rapid racing and rapid accel-
eration immediately after the engine
has started.
 After the engine starts, the engine
speed will be kept high.
CAUTION
Small animals trapped in the cool-
ing fan and belt 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.
WARNING
Never start the engine from
outside the vehicle. 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
poisoning.
 Do not start the engine near dry
foliage, paper, or other flammable
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 overheat
and burn. When starting the engine, be sure
to sit in the driver’s seat.
