side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.
. State or local regulations on
volatile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle ’s paint, wiper blades
or washer system.
! Before driving your vehicle
Before entering the vehicle, remove any
snow or ice from your shoes because that
could make the pedals slippery and
driving dangerous.
While warming up the vehicle before
driving, check that the accelerator pedal,
brake pedal, and all other controls operate
smoothly.
Clear away ice and snow that has
accumulated under the fenders to avoid
making steering difficult. During severe winter driving, stop when and where it is
safe to do so and check under the fenders
periodically.
!
Parking in cold weather
Do not use the parking brake when
parking for long periods in cold weather
since it could freeze in that position.
Instead, you should observe the following
tips.
1. Place the shift lever in “1”or “R”for MT
models, or the select lever in “P”for CVT
models.
2. Use tire stops under the tires to
prevent the vehicle from moving.
When the vehicle is parked in snow or
when it snows, raise the wiper blades off
the glass to prevent damage to them.
When the vehicle has been left parked
after use on roads heavily covered with
snow, or has been left parked during a
snowstorm, icing may develop on the
brake system, which could cause poor
braking action. Check for snow or ice
buildup on the suspension, disc brakes
and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it,
being careful not to damage the disc
brakes and brake hoses and ABS har-
ness.WARNING
Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle if you park
the vehicle in snow with the engine
running.
! Refueling in cold weather
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an
antifreeze additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty.
If your SUBARU is not going to be used
for an extended period, it is best to have
the fuel tank filled to capacity.
! Opening rear gate (models with
power rear gate)
CAUTION
Before operating the power rear
gate, check that there is no frost or
snow between the power rear gate
and the vehicle body. If you notice
Driving tips/Winter driving
–CONTINUED –8-9

Driving tips/Winter driving
frost or snow etc. on the power rear
gate, remove it. If you forcibly
operate the power rear gate with
frost or snow, it may cause a mal-
function.
&Driving on snowy and icy
roads
To prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you
to avoid the need for sudden braking.
To supplement the foot brake, use the
engine brake effectively to control the
vehicle speed. (Shift into a lower gear
when necessary.)
Avoid shifting down abruptly. Such beha-
vior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle’ s braking perfor-
mance on snowy and icy roads. For
information on braking on slippery sur-
faces, refer to “ABS (Anti-lock Brake
System) ”F 7-37 and “Vehicle Dynamics
Control system ”F 7-39.
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of
vehicle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine ’sintakesystemandmay
hinder the airflow, which could re-
sult in engine shutdown or even
breakdown.
! Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blades are not frozen to the
windshield or rear window.
If the wiper blades are frozen to the
windshield or rear window, perform the
following procedure.
. To thaw the windshield wiper blades,
use the defroster with the airflow selection
in “
”and the temperature set for
maximum warmth until the wiper blades
are completely thawed. Refer to “Climate
control ”F 4-1.
. If your vehicle is equipped with a wiper deicer, use it. It is helpful to thaw the
windshield wiper blades. Refer to
“Defog-
ger and deicer ”F 3-116.
. To thaw the rear wiper blade, use the
rear window defogger. Refer to “Defogger
and deicer ”F 3-116.
When driving in snow, if frozen snow starts
to stick on the surface of the windshield
despite wiper operation, use the defroster
with the airflow selection in “
”and the
temperature set for maximum warmth.
After the windshield gets warmed enough
to melt the frozen snow on it, wash it away
using the windshield washer. Refer to
“Windshield washer ”F 3-106.
Snow stuck on the wiper arm prevents the
wiper from working effectively. If snow is
stuck on the wiper arm, pull off the road to
a safe place, then remove it. If you stop
the vehicle at road side, use the hazard
warning flasher to alert other drivers.
Refer to “Hazard warning flasher ”F 3-8.
We recommend use of non-freezing type
wiper blades (winter blades) during the
seasons you could have snow and freez-
ing temperatures. Blades of this type give
superior wiping performance in snowy
conditions. Be sure to use blades that
are suitable for your vehicle.

Driving tips/Trailer towing
refer to“BSD/RCTA OFF switch ”
F 7-64.
. For models equipped with RAB
(Reverse Automatic Braking)
system, consult your SUBARU
dealer for additional information
about towing a trailer.
. Never exceed 45 mph (72 km/h)
when towing a trailer in hilly
country on hot days.
. When towing a trailer, steering,
stability, stopping distance and
braking performance will be dif-
ferent when compared to normal
operation. You should never
drive at excessive speeds but
always employ extra caution
when towing a trailer. You should
also keep the following tips in
mind.
! Before starting out on a trip
. Check that the vehicle and vehicle-to-
hitch mounting are in good condition. If
any problems are apparent, do not tow the
trailer.
. Check that the vehicle rests horizon-
tally with the trailer attached. If the vehicle
is tipped sharply up at the front and down
at the rear, check the total trailer weight,
GVW, GAWs and tongue load again, then confirm that the load and its distribution
are acceptable.
.
Check that the tire rating and pressures
are correct.
. Check that the vehicle and trailer are
connected properly. Confirm that:
–the trailer tongue is connected
properly to the hitch ball.
– the trailer lights connector is con-
nected properly and trailer ’sbrake
lights illuminate when the vehicle ’s
brake pedal is pressed, and that the
trailer ’s turn signal lights flash when
the vehicle’ s turn signal lever is oper-
ated.
– the safety chains are connected
properly.
– all cargo in the trailer is secured
safety in position.
– the side mirrors provide a good
rearward field of view without a sig-
nificant blind spot.
. Sufficient time should be taken to learn
the “feel ”of the vehicle/trailer combination
before starting out on a trip. In an area free
of traffic, practice turning, stopping and
backing up.
! Driving with a trailer
. You should allow for considerably more
stopping distance when towing a trailer.
Avoid sudden braking because it may result in skidding or jackknifing and loss of
control.
.
Avoid abrupt starts and sudden accel-
erations. If your vehicle has a manual
transmission, always start out in first gear
and release the clutch at moderate engine
revolution.
. Avoid uneven steering, sharp turns and
rapid lane changes.
. Slow down before turning. Make a
longer than normal turning radius because
the trailer wheels will be closer than the
vehicle wheels to the inside of the turn. In
a tight turn, the trailer could hit your
vehicle.
. Crosswinds will adversely affect the
handling of your vehicle and trailer, caus-
ing sway. Crosswinds can be due to
weather conditions or the passing of large
trucks or buses. If swaying occurs, firmly
grip the steering wheel and promptly begin
decelerating your vehicle at a gradual
pace.
. When passing other vehicles, consid-
erable distance is required because of the
added weight and length caused by
attaching the trailer to your vehicle.

Maintenance and service/Engine oil
Engine oil
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.
1) Oil level gauge
2) Oil filler cap
3) Oil filter
CAUTION
If the level gauge cannot be pulled
out easily, twist the level gauge right
and left, then pull it out. Otherwise,
you may be injured by accidentally
straining yourself.
2. Pull out the level gauge, wipe it clean,

Maintenance and service/Cooling system
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.
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 is
removed.
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 up 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 mixing
coolant.
. 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 blinks or illuminates in RED,
the cooling fan circuit may be defective.
Refer to “Coolant temperature low indica-
tor light/Coolant temperature high warning
light ”F 3-17.
Check the fuse and replace it if necessary.
Refer to “Fuses”F 11-37 and “Fuses and
circuits ”F 12-12.
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

Maintenance and service/Aluminum wheels
&Wheel replacement
When replacing wheels due, for example,
to damage, make sure the replacement
wheels match the specifications of the
wheels that are fitted as standard equip-
ment. Replacement wheels are available
from SUBARU dealers.
WARNING
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could
interfere with brake caliper opera-
tion and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of
vehicle control could lead to an
accident.
NOTE
When any of the wheels are removed
and replaced for tire rotation or to
change a flat tire, always check the
tightness of the wheel nuts after driv-
ing approximately 600 miles (1,000 km).
If any nut is loose, tighten it to the
specified torque.
Aluminum wheels
Aluminum wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety.
. When any of the wheels are removed
and replaced for tire rotation or to change
a flat tire, always check the tightness of
the wheel nuts after driving approximately
600 miles (1,000 km). If any nut is loose,
tighten it to the specified torque.
. Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.
. Never let the wheel rub against sharp
protrusions or curbs.
. When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for aluminum wheels.
