8-8. Winter Driving■Operation during Cold
WeatherCarry 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 afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that
contains an antifr eeze solution. Do not
use engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.
If you fill the windshield washer tank with
a fluid with a different concentration from
If all four tires are not the same in
items (a) to (h), serious mechani-
cal damage could be caused to
the drivetrain of the car, and
affect the followings.-Ride-Handling- Braking- Speedometer/Odometer cali-
bration- Clearance between the body
and the tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
 In a rollover crash, an unbelted
person is significantly more likely
to die than a person wearing a
seat belt. The driver and all your
passengers should fasten their
seatbelts before st arting to drive
in order to minimize the chance of
serious injury or death. Do not make sharp turns or quick
maneuvers unless absolutely
unavoidable. Such actions are
dangerous as you may lose
control, possibly resulting in a
rollover which could cause death
or serious injury.
 Whenever strong crosswinds are
present, slow do wn sufficiently to
maintain control of your vehicle. Never 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. In this
case, contact your SUBARU
dealer immediat ely. Regardless
of its depth, it can wash away the
ground from under your tires,
resulting in possible loss of trac-
tion and even vehicle rollover.
CAUTION
After driving on gravel roads or
rough roads, check the undercar-
riage of the vehicle body for any
damage, deformation, or paint
removal. If you notice any irregulari-
ties, contact a SUBARU dealer for
an inspection as soon as possible.

Engine Overheating
319
In Case of Emergency9
– CONTINUED –
9-5. Engine Overheating■If Steam Is Coming from the
Engine CompartmentTurn off the engine and get everyone
away from the vehicle until it cools down.
■ If No Steam Is Coming from
the Engine Compartment1. Keep the engine running at idling
speed.
2. Open the hood to ventilate the engine
compartment. Refer to "Engine Hood"
 P343.
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 over-
heated 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.NOTEFor details about how to check the
coolant level or how to add coolant,
refer to "Eng ine Coolant" P349.
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

counterclockwise 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.
WARNING
Never remove the radiator 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 seri-
ously.
CAUTION
If the engine overheats, the engine
speed or the vehicle speed may be
reduced. Stop the vehicle in a safe
place immediately.

Cleaning the Interior
335
Appearance Care10
– CONTINUED –
Check the interior of the vehicle for water
and dirt accumulation under the floor mats
because that could cause corrosion.
Occasionally check under the mats to
make sure the area is dry.
Keep your garage dry. Do not park your
vehicle in a damp, poorly ventilated
garage. In such a garage, corrosion can
be caused by dampness. If you wash the
vehicle in the garage or put the vehicle
into the garage when wet or covered with
snow, that can cause dampness.
If your vehicle is operated in cold weather
and/or in areas where road salts and other
corrosive materials are used, the door
hinges and locks, trun k lid lock, and hood
latch should be inspected and lubricated
periodically.
10-3. Cleaning the InteriorUse a soft, damp cloth to clean the climate
control panel, audio equipment, instru-
ment panel, center console, combination
meter panel, and switches. (Do not use
organic solvents.)■ Seat Fabric MaterialRemove loose dirt, dust or debris with a
vacuum cleaner. If the dirt is caked on the
fabric or hard to remove with a vacuum
cleaner, use a soft brush then vacuum it.
Wipe the fabric surface with a tightly
wrung cloth and dry the seat fabric thor-
oughly. If the fabric is still dirty, wipe using
a solution of mild soap and lukewarm
water then dry thoroughly.
If the stain does not come out, try a
commercially available fabric cleaner. Use
the cleaner on a hidden place and make
sure it does not affect the fabric adversely.
Use the cleaner according to its instruc-
tions.
NOTEAs the color of the meter visor may
transfer, do not place anything on top
of it.■ Leather Seat MaterialsThe leather used by SUBARU is a high
quality natural product which will retain its
distinctive appearance and feel for many
years with proper care.
Allowing dust or road dirt to build up on the
surface can cause leather to become
brittle and wear prematurely. To maintain
its resiliency, leather should be cleaned
monthly or whenever it becomes soiled.
Before cleaning leather upholstery,
vacuum it to remove dust. Use a soft and
lint-free cloth dampened with lukewarm
water and mild soap, taking care not to
soak the leather or allow water to pene-
trate the stitched seams. Use a gentle
circular motion while cleaning the leather -
do not rub or apply extreme pressure.
Wipe the leather again with another clean,
slightly damp cloth to remove soap
residue and dry with a soft cloth.
Minor surface blemishes or difficult dirt
spots may be treated with a commercial
leather spray. Never use alcohol, cleaning
solvents, leather oils, varnishes or
polishes on your leather as it will dry out
the leather finish.
CAUTION
When cleaning the seat, do not use
benzine, paint thinner, or any simi-
lar materials. Doing so could dam-
age the surface and cause the color
to deteriorate.

Maintenance Precautions
340NOTESUBARU does not endorse the use of
non-SUBARU approved flushing sys-
tems and strongly advises against per-
forming these services on a SUBARU
vehicle. Non-SUBARU approved flush-
ing systems use chemicals and/or sol-
vents which have not been tested or
approved by SUBARU. SUBARU war-
ranties do not cover any part of the
vehicle which is damaged by adding or
applying chemicals and/or solvents
other than those approved or recom-
mended by SUBARU.
■ Before Checking or
Servicing in the Engine
Compartment
■When Checking or Servicing
in the Engine Compartment
Do not tamper wi th the wiring of
the SRS airbag system or seatbelt
pretensioner system, or attempt
to take its connectors apart, as
that may activate the system or it
can render it inoperative. NEVER
use a circuit tester for these
wiring. If your SRS airbag or
seatbelt pretensioner needs
service, consult your nearest
SUBARU dealer. Check the inside of the engine
compartment to see if there are
any cloths and tools left. If they
are left inside, they may be a
cause of malfunction and fire.
WARNING
 Always stop the engine and apply
the parking brake to prevent 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 is stopped. Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire. When the ignition switch is in the
“ON” position, the cooling fan
may operate 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. To
avoid risk of injury, always turn
the push-button i gnition switch to
the “OFF” position and confirm
that the operation indicator on
the switch is turn ed off. Then take
the access key fob out from the
vehicle.
 Before performing any servicing
on a vehicle equipped with a
remote engine start system
temporarily place that system in
the service mode to prevent it
from unexpectedly starting the
engine.

Engine Oil
34611-6. Engine Oil■Engine Oil ConsumptionSome 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 followi ng 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 braking 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 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 Level1. Park the vehicle on a level surface and
stop the engine. If you check the oil level
just after stopping the engine, wait for at least 5 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 filter2. Pull out the level gauge, wipe it clean,
and insert it again.
3. Be sure the level gauge is correctly
inserted until it stops.
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 acciden-
tally straining yourself. Use only engine oil with the
recommended grade and
viscosity. 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.
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 acci-
dentally straining yourself.
