Driving tips/Winter driving
need to be washed thoroughly.
.Frequent driving of an AWD model
under hard-driving conditions such as
rough roads or off roads will necessitate
more frequent replacement of the follow-
ing items than that specified in the
maintenance schedule described in the
“Warranty and Maintenance Booklet ”.
– Engine oil
– Brake fluid
– Rear differential gear oil
– Manual transmission oil (MT mod-
els)
– Continuously variable transmission
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 warranty coverage.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-
centration Freezing Temperature
30% 10.4 8F( −12 8C)
50% −48F( −20 8C)
100% −
49 8F( −45 8C)
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-

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, pay
attention to the following indicators be-
cause the engine and transmission are
relatively prone to overheating.: Coolant temperature high warning light
: AT OIL TEMP warning light (CVT models)
If the coolant temperature high warning
light and/or the AT OIL TEMP warning light
illuminates, immediately turn off the air
conditioner and stop the vehicle in the
nearest safe location. For further instruc-
tions and additional information, refer to
the following sections. –“If you park your vehicle in case of
an emergency ”F 9-2
–“ Engine overheating ”F 9-12
–“ Coolant temperature low indicator
light/Coolant temperature high warn-
ing light ”F 3-17 –“
AT OIL TEMP warning light (CVT
models) ”F 3-19
. For CVT models, avoid using 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 firmly. 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 ” position (CVT models)
and shut off the engine.
Driving tips/Trailer towing8-25

In case of emergency/Engine overheating
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, safely pull off the
road and stop the vehicle in a safe
location.
& If steam is coming from the
engine compartment
. Turn off the engine and get everyone
away from the vehicle until it cools down.
. Contact an authorized SUBARU deal-
er.
& If no steam is coming from
the engine compartment
1. Keep the engine running at idling
speed.
2. Open the engine 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 an authorized
SUBARU dealer for repair.
3. After the coolant temperature high
warning light that has blinked or illumi-
nated in REDturns off, turn off the engine.
For details about the warning light, refer to
“Coolant temperature low indicator light/
Coolant temperature high warning light ”
F 3-17.
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.
NOTE
For details about how to check the
coolant level or how to add coolant,
refer to “Engine coolant ”F 11-13.
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.

In case of emergency/Towing
position for CVT models. Shift the shift
lever into the“1st ”position for MT models.
2. Apply the parking brake firmly.
3. Secure the vehicle onto the carrier
properly with safety chains. Each safety
chain should be equally tightened and
care must be taken not to pull the chains
so tightly that the suspension bottoms out.
CAUTION
If your vehicle has a front under-
spoiler and rear underspoiler (both
optional), be careful not to scrape
them when placing the vehicle on
the carrier and when removing the
vehicle from the carrier.
& Towing with all wheels on the
ground
1. Release the parking brake and put the
transmission in the “N”/neutral position.
2. The ignition switch should be in the
“ON ”position while the vehicle is being
towed.
3. Take up slack in the towline slowly to
prevent damage to the vehicle.
WARNING
. Never turn the ignition switch to
the “LOCK ”/“OFF ”position while
the vehicle is being towed be-
cause the steering wheel and the
direction of the wheels will be
locked. .
Remember that the brake booster
and power steering do not func-
tion when the engine is not
running. Because the engine is
turned off, it will take greater
effort to operate the brake pedal
and steering wheel.
CAUTION
. If transmission failure occurs,
transport your vehicle on a flat-
bed truck.
. For CVT models, the traveling
speed must be limited to less
than 20 mph (30 km/h) and the
traveling distance to less than 31
miles (50 km). For greater speeds
and distances, transport your
vehicle on a flat-bed truck.

Maintenance precautions
When maintenance and service are re-
quired, it is recommended that all work be
done by an authorized SUBARU dealer.
If you perform maintenance and service
by yourself, you should familiarize yourself
with the information provided in this
section on general maintenance and
service for your SUBARU.
Incorrect or incomplete service could
cause improper or unsafe vehicle opera-
tion. Any problems caused by improper
maintenance and service performed by
you are not eligible for warranty coverage.
WARNING
. Always select a safe area when
performing maintenance on your
vehicle.
. Always be very careful to avoid
injury when working on the vehi-
cle. Remember that some of the
materials in the vehicle may be
hazardous if improperly used or
handled, for example, battery
acid.
. Your vehicle should only be ser-
viced by persons fully competent
to do so. Serious personal injury may result to persons not experi-
enced in servicing vehicles.
. Always use the proper tools and
make certain that they are well
maintained.
. Never get under the vehicle sup-
ported only by a jack. Always use
safety stands to support the
vehicle.
. Never keep the engine running in
a poorly ventilated area, such as
a garage or other closed areas.
. Do not smoke or allow open
flames around the fuel or battery.
This will cause a fire.
. Because the fuel system is under
pressure, replacement of the fuel
filter should be performed only
by your SUBARU dealer.
. Wear adequate eye protection to
guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly
wash them out with clean water.
. Do not tamper with the wiring of
the SRS airbag system or seat-
belt pretensioner system, or at-
tempt to take its connectors
apart, as that may activate the
system or it can render it inop-

erative. NEVER use a circuit
tester for this wiring. If your
SRS airbag or seatbelt preten-
sioner needs service, consult
your nearest SUBARU dealer.
NOTE
SUBARU does not endorse the use of
non-SUBARU approved flushing sys-
tems and strongly advises against
performing these services on a
SUBARU vehicle. Non-SUBARU ap-
proved flushing systems use chemi-
cals and/or solvents which have not
been tested or approved by SUBARU.
SUBARU warranties do not cover any
part of the vehicle which is damaged by
adding or applying chemicals and/or
solvents other than those approved or
recommended by SUBARU.
&Before checking or servicing
in the engine compartment
WARNING
. Always stop the engine and set
the parking brake firmly to pre-
vent the vehicle from moving.
. Always let the engine cool down.
Engine parts become very hot when the engine is running and
remain hot for some time after
the engine has stopped.
. Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
. Always remove the key from the
ignition switch. When the ignition
switch is in the “ON ”position,
thecoolingfanmayoperate
suddenly even when the engine
is stopped. If your body or
clothes come into contact with a
rotating fan, that could result in
serious injury.
. Before performing any servicing
on a vehicle equipped with a
remote engine start system (a
dealer option), temporarily place
the remote engine start system in
service mode to prevent it from
unexpectedly starting the engine.
CAUTION
. Do not contact the drive belt
cover while checking the compo-
nents in the engine compart-
ment. Doing so may cause your
hand to slip off the cover and
result in an unexpected injury.
. Do not touch the oil filter until the
engine has cooled down comple-
tely. Doing so may result in a
burn or other injury. Note that the
oil filter becomes very hot when
the engine is running and re-
mains hot for some time after
the engine has stopped.

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 accidentally 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
. 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.
