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 ignition switch)
&Starting engine
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.!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.
.When starting the engine, be sure
to sit in the driver’s seat (except

lights, tail lights and parking lights and
honk the horn three times, indicating that
the system has entered the transmitter
learn mode.
5. Press and release the“
”button on
the transmitter that you want to program.
6. The system will flash the side marker
lights, tail lights and parking lights and
honk the horn one time, indicating that the
system has learned the transmitter. Upon
successful programming, the remote start
confirmation transmitter button will flash
one time.
7. Repeat step 5 for any additional
transmitters (the system will accept up toeight transmitters).
8. The system will exit the transmitter
learn mode if the key is turned to the
“LOCK”position, the door is closed or
after 2 minutes.
&System maintenance
NOTE
For models without“keyless access
with push-button start system”:
In the event that the vehicle’s battery is
replaced, discharged or disconnected,
it will be necessary to start the vehicle
a minimum of one time using the key
prior to activating the remote engine
start system. This is required to allow
the vehicle electronic systems to re-
synchronize.
!Changing the batteries
CAUTION
.Do not let dust, oil or water get on
or in the remote engine start
transmitter when replacing the
battery.
.Be careful not to damage the
printed circuit board in the re-
mote engine start transmitter
when replacing the battery..Be careful not to allow children to
touch the battery and any re-
moved parts; children could
swallow them.
.There is a danger of explosion if
an incorrect replacement battery
is used. Replace only with the
same or equivalent type of bat-
tery.
.Batteries should not be exposed
to excessive heat such as sun-
shine, fire or the like.
For models with“keyless access with
push-button start system:
Perform the procedure described in“Re-
placing battery of access key”F11-50.
For models without“keyless access
with push-button start system”:
The 3-volt lithium battery (model CR-
2032) supplied in your remote engine start
transmitter should last approximately one
year, depending on usage. When the
battery begins to weaken, you will notice
a decrease in range (distance from the
vehicle that your remote control operates).
Follow the instructions below to change
the remote engine start transmitter battery.

While driving with the select lever in the
“D”position, if you change gears by
operating the shift paddle, the gear posi-
tion indicator light illuminates and shows
the current gear condition.
CAUTION
Do not place or hang anything on
the shift paddles. Doing so may
result in accidental gear shifting.
NOTE
Please read the following points care-
fully and bear them in mind when using
the manual mode.
.If you attempt to shift down when
the engine speed is too high, i.e., when
a downshift would push the tachometer
needle beyond the red zone, beeps will
be emitted to warn you that the down-
shift is not possible.
.If you attempt to shift up when the
vehicle speed is too low, the transmis-
sion will not respond.
.You can perform a skip-shift (for
example, from 4th to 2nd) by operating
the shift paddle twice in rapid succes-
sion.
.The transmission automatically se-
lects 1st gear when the vehicle stops
moving.
.If the temperature of the transmis-
sion fluid becomes too high, the“AT
OIL TEMP”warning light will illuminate.
Immediately stop the vehicle in a safe
place and let the engine idle until thewarning light turns off.
&Driving tips
.On a road surface where there is a risk
of wheelspin (for example, a snow- or
gravel-covered road), you can pull away
from a standstill safely and easily by first
selecting the 2nd gear of the manual
mode.
.Always apply the foot or parking brake
when the vehicle is stopped in the“D”or
“R”position.
.Always apply the parking brake when
parking your vehicle. Do not hold the
vehicle with only the transmission.
.Do not keep the vehicle in a stationary
position on an uphill grade by using the
“D”position. Use the brake instead.
.The engine may, on rare occasions,
knock when the vehicle rapidly acceler-
ates or rapidly pulls away from a standstill.
This phenomenon does not indicate a
malfunction.
.A slight reduction in output torque may
occur in the models with a 3.6 L engine
before the engine warms up.

.Hill descent control function:
Using the hill descent control function, you
can keep the vehicle at a consistent speed
driving downhill. If the vehicle speed is
likely to increase, the brake control system
will be activated to adjust the vehicle
speed.
.Driving ability control:
This mode increases the hill-climbing
ability and driving ability as well as
enabling smooth application of torque for
easier control of the steering wheel.

conditions than a two wheel drive vehicle.
There is little difference in handling,
however, during extremely sharp turns or
sudden braking. Therefore, when driving
down a slope or turning corners, be sure
to reduce your speed and maintain an
ample distance from other vehicles.
.Always check the cold tire pressure
before starting to drive. The recom-
mended tire pressure is provided on the
tire placard, which is located on the door
pillar on the driver’s side.
.There are some precautions that you
must observe when towing your vehicle.
For detailed information, refer to“Towing”
F9-13.Off road driving
WARNING
.Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden brak-
ing or under other similar condi-
tions.
.Always use the utmost care in
driving–overconfidence be-
cause you are driving an All-
Wheel Drive vehicle could easily
lead to a serious accident.
&Legacy
Your AWD vehicle is neither a conven-
tional off-road vehicle nor an all terrain
vehicle. It is a passenger car designed
primarily for on-road use. The AWD
feature gives it some limited off-road
capabilities in situations in which the
driving surface is relatively level, obstruc-
tion-free and otherwise similar to on-road
driving conditions. Operating it under other
than those conditions could subject the
vehicle to excessive stress which might
result in damage not eligible for repairunder warranty. If you do take your
SUBARU off road, you should review the
common sense precautions in the next
section (applicable to the Outback) for
general guidance. But please keep in
mind that your vehicle’s off-road capabil-
ities are more limited than those of the
Outback.
Never attempt to drive through pools and
puddles, or roads flooded with water.
Water entering the engine air intake or
the exhaust pipe or water splashing onto
electrical parts may damage your vehicle
and may cause it to stall.
&Outback
CAUTION
Frequent driving of an AWD model
under hard-driving conditions such
as rough roads or off roads will
necessitate more frequent replace-
ment of the following items than that
specified in the maintenance sche-
dule described in the“Warranty and
Maintenance Booklet”.
.Engine oil
.Brake fluid
.Manual transmission oil (MT
models)
8-6

.Continuously variable transmis-
sion fluid (CVT models)
.Front differential gear oil (CVT
models)
Remember that damage done to
your SUBARU while operating it
off-road and not using common
sense precautions such as those
listed above is not eligible for war-
ranty coverage.
Because of the AWD feature and higher
ground clearance, you can drive your
SUBARU on ordinary roads or off-road.
But please keep in mind that an AWD
SUBARU is a passenger car and is
neither a conventional off-road vehicle
nor an all-terrain vehicle. If you do take
your SUBARU off-road, certain common
sense precautions such as those in the
following list should be taken.
!Before driving
.Make certain that you and all of your
passengers are wearing seatbelts.
.Carry some emergency equipment,
such as a towing rope or chain, a shovel,
wheel blocks, first aid kit and cell phone or
citizens band radio.
.Secure all cargo carried inside the
vehicle and make certain that it is not
piled higher than the seatbacks. Duringsudden stops or jolts, unsecured cargo
could be thrown around in the vehicle and
cause injury. Do not pile heavy loads on
the roof. Those loads raise the vehicle’s
center of gravity and make it more prone
to tip over.
.Never equip your vehicle with tires
larger than those specified in this manual.
!During driving
General precautions:
.Drive carefully. Do not take unneces-
sary risks by driving in dangerous areas or
over rough terrain.
.Slow down and employ extra caution at
all times. When driving off-road, you will
not have the benefit of marked traffic
lanes, banked curves, traffic signs and
the like.
.Do not drive across steep slopes.
Instead, drive either straight up or straight
down the slopes. A vehicle can much
more easily tip over sideways than it can
end over end. Avoid driving straight up or
down slopes that are too steep.
.Avoid sharp turning maneuvers, espe-
cially at higher speeds.
.Do not grip the inside or spokes of the
steering wheel. A bad bump could jerk the
wheel and injure your hands. Instead,
drive with your fingers and thumbs on
the outside of the rim..Do not drive or park over or near
flammable materials such as dry grass or
fallen leaves, as they may burn easily. The
exhaust system is very hot while the
engine is running and right after the
engine stops. This could create a fire
hazard.
Precautions when driving under espe-
cially dangerous situations:
.If driving through water, such as when
crossing shallow streams, first check the
depth of the water and the bottom of the
stream bed for firmness and ensure that
the bed of the stream is flat. Drive slowly
and completely through the stream. The
water should be shallow enough that it
does not reach the vehicle’s undercar-
riage. Water entering the engine air intake
or the exhaust pipe or water splashing
onto electrical parts may damage your
vehicle and may cause it to stall. Never
attempt to drive through rushing water;
regardless of its depth, it can wash away
the ground from under your tires, resulting
in possible loss of traction and even
vehicle rollover.
.If you must rock the vehicle to free it
from sand or mud, depress the accelerator
pedal slightly and move the shift lever/
select lever back and forth between“1”/
“D”and“R”repeatedly. Do not race the
engine. For the best possible traction,
Driving tips/Off road driving
–CONTINUED–8-7

Driving tips/Winter driving
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”F7-29.
!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.SUBARU Windshield Washer Fluid con-
tains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the following
table.
Washer Fluid Con-
centrationFreezing Temperature
30% 10.48F(−128C)
50%−48F(−208C)
100%−498F(−458C)
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside
temperature, it may freeze and block the
nozzles.
CAUTION
.Adjust the washer fluid concen-
tration appropriately for the out-

Driving tips/Trailer towing (Outback)
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 theengine 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”F9-13.
–Temperature gauge needle ap-
proaches the OVERHEAT zone. Refer
to“Temperature gauge”F3-11.
–AT OIL TEMP warning light illumi-
nates (CVT models). Refer to“AT OIL
TEMP warning light (CVT models)”
F3-16.
.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.
8-28

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
NOTE
For details about how to check the
coolant level or how to add coolant,
refer to“Engine coolant”F11-14.
1. Keep the engine running at idling
speed.2. Open the hood to ventilate the engine
compartment. Refer to“Engine hood”
F11-7.
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 temperature gauge stays in the
overheated 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.
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.
Towing
WARNING
Never tow AWD vehicles 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, SUBARU recom-
mends it be done by your SUBARU dealer
or a commercial towing service.
