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.

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.

Engine Overheating
319
In Case of Emergency9
– CONTINUED –
9-5. Engine Overheating■If Steam Is Coming from the
Engine CompartmentTurn off the engine and get everyone
away from the vehicle until it cools down.
■ If No Steam Is Coming from
the Engine Compartment1. Keep the engine running at idling
speed.
2. Open the hood to ventilate the engine
compartment. Refer to "Engine Hood"
 P343.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the temperature gauge stays in the over-
heated zone, turn off the engine.
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.NOTEFor details about how to check the
coolant level or how to add coolant,
refer to "Eng ine Coolant" P349.
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

counterclockwise 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.
WARNING
Never remove the radiator 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 seri-
ously.
CAUTION
If the engine overheats, the engine
speed or the vehicle speed may be
reduced. Stop the vehicle in a safe
place immediately.

Engine Oil
34611-6. Engine Oil■Engine Oil ConsumptionSome engine oil will be consumed while
driving. The rate of consumption can be
affected by such factors as transmission
type, driving style, terrain and tempera-
ture. Under the followi ng conditions, 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
(repeatedly)
 When the engine is operated at high
engine speeds (for extended periods of
time)
 When the engine is operated under
heavy loads (for extended periods of time)
 When the engine idles for extended
periods of time
 When the vehicle is operated in stop
and go and/or heavy traffic situations
 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. Different drivers in the
same car may experience different
results. If your oil consumption rate is
greater than expected, contact your
authorized SUBARU retailer who may
perform a test under controlled conditions.
■ Checking the Oil Level1. Park the vehicle on a level surface and
stop the engine. If you check the oil level
just after stopping the engine, wait for at least 5 minutes for the oil to drain back into

the oil pan before checking the level.
1) Oil level gauge
2) Oil filler cap
3) Oil filter2. Pull out the level gauge, wipe it clean,
and insert it again.
3. Be sure the level gauge is correctly
inserted until it stops.
CAUTION
 If the level gauge is not pulled out
easily, twist the level gauge right
and left, then pull it out. Other-
wise, you may be injured acciden-
tally straining yourself. Use only engine oil with the
recommended grade and
viscosity. Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.
CAUTION
If the level gauge cannot be pulled
out easily, twist the level gauge
right and left, then gently pull it out.
Otherwise, you may be injured acci-
dentally straining yourself.

1) Full level
2) Low level
3) Approximately 1.1 US qt (1.0 liter, 0.9

Imp qt) from low level to full level
4. Pull out the oil level gauge again.
5. Check the oil levels on both sides of
the level gauge. The engine oil level must
be judged by the lowest of the two levels.
If the oil level is below the low level mark,
add oil so that the full level is reached. To add engine oil, remove the engine oil
filler cap and slowly pour engine oil
through the filler neck. After pouring oil
into the engine, you must use the level
gauge to confirm that the oil level is

correct.
NOTE To prevent overfilling the engine oil,
do not add any additional oil above the
full level when the engine is cold.
■ Changing the Oil and Oil
FilterChange the oil and oil filter according to
the maintenance schedule in the
“Warranty and Maintenance Booklet”.
NOTE Changing the engine oil and oil filter
should be performed by a well-trained
expert. Contact your SUBARU dealer
for changing the engine oil and oil
filter. Fully trained mechanics are on
standby at a SUBARU dealer to utilize
the special tools, spare parts and
recommended oil for this work, and
also, used oils are properly disposed
of.
 If performing oil replacement your-
self, observe the local regulations and
dispose of waste oil properly.■ Recommended Grade and
ViscosityRefer to "Engine Oil" P381.NOTEEngine oil viscosity (thickness) affects
fuel economy. Oils of lower viscosity
provide better fuel economy. How-
ever, in hot weather, oil of higher vis-
cosity is required to properly lubricate
the engine.
CAUTION
 Be careful not to touch the engine
oil filter when removing the oil
filler cap. Doing so may result in a
burn, a pinched finger, or may
cause some other injury.

when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
