Instruments and controls/Warning and indicator lights
&CHECK ENGINE
warning light/Malfunc-
tion indicator light
CAUTION
If the CHECK ENGINE warning light/
malfunction indicator light illumi-
nates while you are driving, have
your vehicle checked/repaired by
your SUBARU dealer as soon as
possible. Continued vehicle opera-
tion without having the emission
control system checked and re-
paired as necessary could cause
serious damage, which may not be
covered by your vehicle’s warranty.
If this light illuminates steadily or blinks
while the engine is running, it may indicate
that there is a problem or potential
problem somewhere in the emission con-
trol system.
! If the light illuminates constantly
If the light illuminates constantly while
driving or does not turn off after the engine
starts, an emission control system mal-
function has been detected.
You should have your vehicle checked by
an authorized SUBARU dealer immedi-
ately.
NOTE
This light also illuminates when the fuel
filler cap is not tightened until it clicks.
If you have recently refueled your vehicle,
the cause of the CHECK ENGINE warning
light/malfunction indicator light coming on
could be a loose or missing fuel filler cap.
Remove the cap and retighten it until it
clicks. Make sure nothing is interfering
with the sealing of the cap. Tightening the
cap will not make the CHECK ENGINE
warning light/malfunction indicator light
turn off immediately. It may take several
driving trips. If the light does not turn off,
take your vehicle to your authorized
SUBARU dealer immediately.
! If the light is blinking
If the light is blinking while driving, an
engine misfire condition has been de-
tected which may damage the emission
control system.
To prevent serious damage to the emis-
sion control system, you should conform
to the following instructions.
. Reduce vehicle speed.
. Avoid hard acceleration.
. Avoid steep uphill grades.
. Reduce the amount of cargo, if possi-
ble.
. Stop towing a trailer as soon as
possible. The CHECK ENGINE warning light/mal-
function indicator light may stop blinking
and illuminate steadily after several driv-
ing trips. You should have your vehicle
checked by an authorized SUBARU deal-
er immediately.
&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
3-16

Climate control/Air filtration system
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 circuit
Operate 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 sea-
son
Check the air conditioner unit for refriger-
ant leaks, hose conditions, and proper
operation each spring. Have the air con-
ditioning system checked by your
SUBARU dealer.
&Cooling and dehumidifying in
high humidity and low tem-
perature weather condition
Under certain weather conditions (high
relative humidity, low temperatures, etc.) a
small amount of water vapor emission
from the air outlets may be noticed. This
condition is normal and does not indicate any problem with the air conditioning
system.
&
Air conditioner compressor
shut-off when engine is
heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is designed
to temporarily shut off during air condi-
tioner operation whenever the accelerator
is fully depressed such as during rapid
acceleration or when driving on a steep
upgrade.
&Refrigerant for your climate
control system
Your air conditioner uses ozone friendly
refrigerant HFO-1234yf. Therefore, the
method of adding, changing or checking
the refrigerant is different from the method
for CFC12 (freon) or HFC134a. Consult
your SUBARU dealer for service. Repairs
needed as a result of using the wrong
refrigerant are not covered under war-
ranty.
Air filtration system (if
equipped)
Your vehicle’ s air conditioning system is
equipped with an air filtration system.
Replace the air filter element according
to the replacement schedule shown in the
following table. This schedule should be
followed to maintain the filter ’sdust
collection ability. Under extremely dusty
conditions, the filter should be replaced
more frequently. Have your filter checked
or replaced by your SUBARU dealer. For
replacement, use only a genuine
SUBARU air filter kit. For the replacement
schedule, refer to the “Warranty and
Maintenance Booklet ”.
CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter.
.Reduction of the airflow through
the vents.
. Windshield gets easily fogged or
misted.
NOTE
The filter can influence the air condi-
tioning, heating and defroster perfor-

Driving tips/Winter driving
select lever back and forth between“1 ”/
“D ”and “R”repeatedly. Do not race the
engine. For the best possible traction,
avoid spinning the wheels when trying to
free the vehicle.
. When the road surface is extremely
slippery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st (both for MT and CVT). For
CVT models, refer to “Selection of manual
mode ”F 7-29.
! After driving
. Always check your brakes for effec-
tiveness immediately after driving in sand,
mud or water. Do this by driving slowly
and stepping on the brake pedal. Repeat
that process several times to dry out the
brake discs and brake pads.
. After driving through tall grass, mud,
rocks, sand, rivers, etc., check that there
is no grass, bush, paper, rags, stones,
sand, etc. adhering to or trapped on the
underbody. Clear off any such matter from
the underbody. If the vehicle is used with
these materials trapped or adhering to the
underbody, a mechanical breakdown or
fire could occur. .
Wash the vehicle’ s underbody after off-
road driving. Suspension components are
particularly prone to dirt buildup, so they
need to be washed thoroughly.Winter driving
& Operation during cold
weather
Carry some emergency equipment, such
as a window scraper, a bag of sand,
flares, a small shovel and jumper cables.
Check the battery and cables. Cold
temperatures reduce battery capacity.
The battery must be in good condition to
provide enough power for cold winter
starts.
It normally takes longer to start the engine
in very cold weather conditions. Use an
engine oil of a proper grade and viscosity
for cold weather. Using heavy summer oil
will make it harder to start the engine.
Keep the door locks from freezing by
squirting them with deicer or glycerin.
Forcing a frozen door open may damage
or separate the rubber weather strips
around the door. If the door is frozen,
use hot water to melt the ice, and after-
wards thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.

1) Left turn
2) Right turn
.Backing up with a trailer is difficult and
takes practice. When backing up with a
trailer, never accelerate or steer rapidly.
When turning back, grip the bottom of the
steering wheel with one hand and turn it to
the left for a left turn, and turn it to the right
for a right turn.
. If the ABS warning light illuminates
while the vehicle is in motion, stop towing
the trailer and have repairs performed
immediately by your nearest SUBARU
dealer.
! Driving on grades
. Before going down a steep hill, slow
down and shift into lower gear (if neces-
sary, use 1st gear) in order to utilize the engine braking effect and prevent over-
heating of your vehicle’
s brakes. Do not
make sudden downshifts.
. When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating.
. When driving uphill in hot weather,
because the engine and transmission are
relatively prone to overheating, pay atten-
tion to the following items.
–Temperature gauge
– AT OIL TEMP warning light (CVT
models)
. If any of the following conditions occur,
immediately turn off the air conditioner and
stop the vehicle in the nearest safe
location. Refer to “If you park your vehicle
in an emergency ”F9-2 and “Engine
overheating ”F 9-13.
– Temperature gauge needle ap-
proaches the OVERHEAT zone. Refer
to “Temperature gauge ”F 3-12.
– AT OIL TEMP warning light illumi-
nates (CVT models). Refer to “AT OIL
TEMP warning light (CVT models) ”
F 3-17.
. For CVT models, do not use the
accelerator pedal to stay stationary on
an uphill slope instead of using the
parking brake or foot brake. That may
cause the transmission fluid to overheat. !
Parking on a grade
Always block the wheels under both
vehicle and trailer when parking. Apply
the parking brake. You should not park on
a hill or slope. If parking on a hill or slope
cannot be avoided, you should take the
following steps:
1. Apply the brakes and hold the pedal
down.
2. Have someone place wheel blocks
under both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then
apply the parking brake; slowly release
the regular brakes.
5. Shift into 1st or reverse gear (MT
models) or “P”(CVT models) and shut
off the engine.

Engine oil
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 acci-
dentally straining yourself.
. Use only engine oil with the
recommended grade and vis-
cosity.
. 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.
& Engine oil consumption
Some 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 following 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 brakin g 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 towing a trailer (Outback)
. 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 level
1. Park the vehicle on a level surface and
stop the engine. If you check the oil level
just after stopping the engine, wait a few
minutes for the oil to drain back into the oil
pan before checking the level.

CAUTION
.For 2.5 L models, 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.
. Use only engine oil with the
recommended grade and vis-
cosity.
. 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.
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 filter
Change the oil and oil filter according to
the maintenance schedule in the “War-
ranty 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 recom-
mended 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
viscosity
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
Refer to “Engine oil ”F 12-4.
NOTE
Engine oil viscosity (thickness) affects
fuel economy. Oils of lower viscosity provide better fuel economy. However,
in hot weather, oil of higher viscosity is
required to properly lubricate the en-
gine.
&
Synthetic oil
You should use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using
synthetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner ’s Manual. Refer to “Engine
oil ”F 12-4. Also, you must follow the oil
and filter changing intervals shown in the
Warranty and Maintenance booklet.
NOTE
Synthetic oil of the grade and viscosity
noted in chapter 12 is the recom-
mended engine oil for optimum engine
performance. Conventional oil may be
used if synthetic oil is unavailable.
Maintenance and service/Engine oil11-13

Manual transmission oil
It is unnecessary to check the manual
transmission oil level. However, if neces-
sary, consult your SUBARU dealer for
inspection.
&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 12-7.
Continuously variable trans-
mission fluid
There is no fluid level gauge. It is
unnecessary to check the continuously
variable transmission fluid level. However,
if necessary, consult your SUBARU dealer
for inspection.
Front differential gear oil
(CVT models) and rear differ-
ential gear oil
It is not necessary to check the gear oil
level. Check that there are no cracks,
damage or leakage. However, the oil
inspection should be performed according
to the maintenance schedule in the
“Warranty and Maintenance Booklet ”.
Consult your SUBARU dealer for details.
& 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 12-7.
CAUTION
Using a differential gear oil other
than the specified oil may cause a
decline in vehicle performance.
