it indicates fuel-efficient driving.
Except U.S.-spec. models:
If the current rate of fuel consumption is
lower than the average rate of fuel
consumption, the indicator needle points
to the “ ” side. If the current rate of fuel
consumption is higher than the average
rate of fuel consumption, the indicator
needle points to the “+ ” side. When the
indicator needle is pointing to the “ ” side,
it indicates fuel-efficient driving.
NOTE . The ECO gauge shows only an
approximate indication. . After resetting the trip meter, the
average rate of fuel consumption is not
shown until driving 0.6 mile (1 km).
Until that time, the ECO gauge does notoperate. Warning and indicator lights
Several of the warning and indicator lights
illuminate momentarily and then go out
when the ignition switch is initially turned
to the
“ON ”position. This permits check-
ing the operation of the bulbs.
Apply the parking brake and turn the
ignition switch to the “ON ”position. The
following lights illuminate:
: Seatbelt warning light (The seatbelt warning light turns off
only when the driver fastens theseatbelt.)

turns off when the engine is warmed up
sufficiently.
If the engine coolant temperature in-
creases over the appropriate range, the
indicator light/warning light blinks in RED.
At this time, decelerate the vehicle. After
the blinking REDlight turns off, you can
drive the vehicle normally. However, if the
indicator light/warning light often blinks inRED , the electrical system may be mal-
functioning. Contact your SUBARU dealer
for an inspection.
If the engine coolant temperature in-
creases further, the indicator light/warning
light illuminates in REDcontinuously. At
this time, the engine may be overheating.
Safely stop the vehicle as soon as
possible, and refer to the emergency
steps for the case of engine overheating.
Refer to “Engine overheating ”F9-12.
After that, have the system checked by
your nearest SUBARU dealer.
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
CAUTION
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.
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 remains
illuminated, contact your nearest
SUBARU dealer immediately.
& Engine low oil level
warning light
The engine low oil level warning light
illuminates when the ignition switch is
turned to the “ON ”position and turns off
after approximately 2 seconds.
This light also illuminates when the engine
oil level decreases to the lower limit. The
illuminating conditions and remaining oil
level are shown in the following items.
2.5 L models:. when the ignition switch is in the “ON ”
position but the engine is not running:
approximately 1.9 US qt (1.8 liters, 1.6
Imp qt) . while the engine is running: approxi-
mately 3.2 US qt (3.0 liters, 2.6 Imp qt)
3.6 L models: . when the ignition switch is in the “ON ”
position but the engine is not running:
approximately 4.0 US qt (3.8 liters, 3.3
Imp qt) . while the engine is running: approxi-
mately 5.6 US qt (5.3 liters, 4.7 Imp qt)
If the engine low oil level warning light
illuminates while driving, park the vehicle

at 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 if necessary.
Refer to“Engine oil ”F 11-12.
If the warning light does not turn off after
refilling with engine oil or the warning light
illuminates even though the engine oil
level is within the normal range, have the
system checked by a SUBARU dealer.
NOTE . The engine low oil level warning
light will not turn off immediately even
if you replace or add engine oil. It will
turn off only when the vehicle is idling
and the engine is warmed up comple-
tely.. When the vehicle is considerably
inclined on an uphill or steep slope, the
warning light may illuminate tempora-
rily due to the movement of engine oil
in the engine. & AT OIL TEMP warning
light (AT and CVT mod-els)
The AT oil temperature warning light “AT
OIL TEMP ”illuminates when the ignition
switch is turned to the “ON ”position and
turns off after approximately 2 seconds. 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, im-
mediately stop the vehicle in a safe place
and let the engine idle until the warning
light turns off. !
Transmission control system warn- ing
If the “AT OIL TEMP ”warning light flashes
after the engine has started, it may
indicate that the transmission control
system is not working properly. Contact
your nearest SUBARU dealer for service
immediately.
& Low tire pressure
warning light (U.S.-spec. models)
When the ignition switch is turned to the “ON ”position, the low tire pressure warn-
ing light will illuminate for approximately 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 thosetires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illuminates
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 TPMS is not a
substitute for proper tire maintenance,
and it is the driver ’s responsibility to
maintain correct tire pressure, even if
under-inflation 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 not operating properly.
The TPMS malfunction indicator is com- Instruments and controls

9-12In case of emergency
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, pull off the road
safely and stop the vehicle in a safe place.
& If steam is coming from the
engine compartment
Turn off the engine and get everyone
away from the vehicle until it cools down. & If no steam is coming from
the engine compartment
For details about how to check the coolant
level or how to add coolant, refer to“ Engine coolant ”F 11-18.
1. Keep the engine running at idlingspeed.
2. Open the hood to ventilate the engine compartment. Refer to
“Engine hood ”
F 11-7.
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 coolant temperature high warning
light illuminates, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reservetank.
If the coolant level is below the “MIN ”
mark, add coolant up to the “MAX ”mark.
Refer to “Engine coolant ”F11 - 1 8 f o r
details.
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. TowingWARNING
Never tow AWD vehicles (including
AT, MT and CVT) with the front
wheels raised off the ground while
the rear wheels are on the ground,
or with the rear wheels raised off the
ground while the front wheels are on
the ground. This will cause the
vehicle to spin away due to the
operation or deterioration of the
center differential.
If towing is necessary, it is best done by
your SUBARU dealer or a commercial
towing service. Observe the following

&Recommended grade and
viscosity under severe driv-
ing conditions
If the vehicle is used in desert areas, in
areas with very high temperatures, or
used for heavy-duty applications such as
towing a trailer, use of oil with the following
grade and viscosities is recommended.
API classification SM or SL: SAE viscosity No.:30, 40, 10W-50, 20W-40, 20W-50 Cooling system
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.
CAUTION
. Vehicles are filled at the factory
with SUBARU Super Coolant that
does not require the first change
for 11 years/137,500 miles (11
years/220,000 km). This coolant
should not be mixed with any
other brand or type of coolant
during this period. Mixing with a
different coolant will reduce the
life of the coolant. Should it be
necessary to top off the coolant
for any reason, use only
SUBARU Super Coolant.
If the SUBARU Super Coolant is
diluted with another brand or
type, the maintenance interval is shortened to that of the mixingcoolant.
. 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 illuminates, the cooling fan
circuit may be defective. Check the fuse
and replace it if necessary. Refer to“ Fuses ”F 11-48 and “Fuses and circuits ”
F 12-6. 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. Maintenance and service

11-18Maintenance and service
&Engine coolant
! Checking the coolant level
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
in the “Warranty and Maintenance Book-
let ”.
