Catalytic converter
The catalytic converter is installed in the exhaust sys-
tem. It serves as catalyst to reduce HC, CO and NOx
in exhaust gases, thus providing cleaner exhaust.
To avoid damage to the catalytic converter:
Use only unleaded fuel. Even a small amount of
leaded fuel will damage the catalytic converter. Never start the engine by pushing or pulling the ve-
hicle. Avoid racing the engine.
Never turn off the ignition switch while the vehicle is
moving.
Keep your engine tuned-up. If you feel the engine
running rough (misfiring, backfiring or incomplete
combustion), have your vehicle checked and repaired
by an authorized SUBARU dealer. Do not apply undercoating or rust prevention treat-
ment to the heat shield of catalytic converter and the
exhaust system.
Avoidfirehazards.Donotdriveorparkthe
vehicle anywhere near flammable materials
(e.g. grass, paper, rags or leaves), because the
catalytic converter operates at very high tem-
peratures. Keep everyone and flammable materials
away from the exhaust pipe while the engine is
running. The exhaust gas is very hot.

Driving tips for AWD vehicles
All wheel drive distributes the engine power to all four
wheels. AWD vehicles provide better traction when
driving on slippery, wet or snow-covered roads and
when moving out of mud, dirt and sand. By shifting
power between the front and rear wheels, SUBARU
AWD can also provide added traction during acceler-
ation and added engine braking force during deceler-
ation.
Therefore, your SUBARU AWD vehicle may handle
differently than an ordinary two wheel drive vehicle
and it contains some features unique to AWD. For
safety purposes as well as to avoid damaging the
AWD system, you should keep the following tips inmind:
An AWD vehicle is better able to climb steeper
roads under snowy or slippery conditions than a two
wheel drive vehicle. There is little difference in han-
dling, however, during extremely sharp turns or sud-
den braking. Therefore, when driving down a slope or
turning corners, be sure to reduce your speed and
maintain an ample distance from other vehicles. When replacing a tire, make sure you use only the
same size, construction, brand, and load range as the
original tires listed on the tire placard. Using other siz-
es or construction may result in severe mechanical
damage to the drive train of your vehicle and may af-
fect ride, handling, braking, speedometer/odometer
calibration, and clearance between the body and tires.
It also may be dangerous and lead to loss of vehicle control. Always check the cold tire pressure before starting
to drive. The recommended tire pressure is provided
on the tire placard, which is located under the door
latch on the driver’s side. Tire chains should always be placed on the front
wheels only. There are some precautions that you must observe
when towing your vehicle. For detail information, see

the “Towing” section in chapter 9.
Always maintain a safe driving speed accord-
ing to the road and weather conditions in order
to avoid having an accident on a sharp turn,
during sudden braking or under other similar
conditions. Always use the utmost care in driving – over-
confidence because you are driving an all
wheel drive vehicle could easily lead to a seri-
ous accident.
Off road driving
Because of the AWD feature and higher ground clear-
ance, your Subaru can be driven on ordinary roads or
off-road. But please keep in mind that an AWD
SUBARU is a passenger car and is neither a conven-
tional off-road vehicle nor an all-terrain vehicle. If you
do take your Subaru off-road, certain common sense
precautions such as the following should be taken: Make certain that you and all of your passengers
are wearing seat belts. Carry some emergency equipment, such as a tow-
ing rope or chain, a shovel, wheel blocks, first aid kit
and portable phone or citizens band radio. Drive carefully. Do not take unnecessary 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 ei-
ther 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, especially at higher
speeds.

Driving tips

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. 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 com-
pletely through the stream. The water should be shal-
low enough that it does not reach the vehicle’s
undercarriage. 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; re-
gardless of its depth, it can wash away the ground
from under your tires, resulting in possible loss of trac-
tion and even vehicle rollover. Always check your brakes for effectiveness immedi-
ately after driving in sand, mud or water. Do this by
driving slowly and stepping on the brake pedal. Re-
peat that process several times to dry out the brake
discs and brake pads. Do not drive or park over or near flammable materi-
als 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.
After driving through tall grass, mud, rock, sand, riv-
ers, 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 under-
body. If the vehicle is use d with these materials
trapped or adhering to the underbody, a mechanical
breakdown or fire could occur. Secure all cargo carried inside the vehicle and make
certain that it is not piled higher than the seatbacks.
During sudden 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. If you must rock the vehicle to free it from sand or
mud, depress the accelerator pedal slightly and move
the selector lever back and forth between “D” and “R”
repeatedly. Do not race the engine. For the best pos-
sible 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 AT). Never equip your vehicle with tires larger than those
specified in this manual. Frequent driving of an AWD vehicle under hard-driv-
ing conditions such as rough roads or off roads will ne-

cessitate more frequent replacement of engine oil,
brake fluid and transmission oil than that specified in
the maintenance schedule described in the “Warranty
and Maintenance Booklet”.
Remember that damage done to your Subaru while
operating it off-road and not using common sense pre-
cautions such as those listed above is not eligible for
warranty coverage.
Always maintain a safe driving speed accord-
ing to the road and weather conditions in order
to avoid having an accident on a sharp turn,
during sudden braking or under other similar
conditions. Always use the utmost care in driving – over-
confidence because you are driving an all
wheel drive vehicle could easily lead to a seri-
ous accident.
Winter driving Operation during cold weather
Carry some emergency equipment, such as tire
chains, a window scraper, a bag of sand, flares, a
small shovel, and jumper cables.
Check the battery and cables. Cold temperatures re-
duce battery capacity. The battery must be in good
condition to provide enough power for cold winterstarts.
Use an engine oil of proper grade and viscosity for
cold weather. Heavy summer oil will cause harder

starting.
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 anti-
freeze solution. Do not use engine antifreeze or other
substitutes because they may damage the paint of the
vehicle.
Before driving your vehicle
Before entering the vehicle, remove any snow or ice
from your shoes because that could make the pedals
slippery and 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.
Parkingincoldweather
Do not use the parking brake when parking for long
periods in cold weather since it could freeze in that po-
sition. Instead, observe the following:
1. Place the shift lever in “1” or “R” for manual trans-
mission vehicles, and in “P” for automatic transmission
vehicles.
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 harness.
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.
Refuelingincoldweather
To help prevent moisture from forming in the fuel sys-
tem and the risk of its freezing, use of an antifreeze ad-
ditive 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 extend-
ed period, it is best to have the fuel tank filled to capac-
ity. Drivingonsnowyandicyroads
To prevent skidding and slipping, avoid sudden brak-
ing, 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 sud-
den 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 behavior can
cause the wheels to lock, possibly leading to loss of
vehicle control.
An anti-lock brake system (ABS) enhances your vehi-
cle’s braking performance on snowy and icy roads.
Refer to the “ABS (Anti-lock Brake System)” section in
chapter 7 for information on braking on slippery sur-
faces.
Do not use the cruise control on slippery roads
such as snowy or icy roads. This may cause
loss of vehicle control.
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, use the defroster with the airflow control but-
ton/dial in the “ ” position and the temperature con-
trol dial set for maximum warmth until the wiper blades
are completely thawed out. If your vehicle is equipped
with a wiper deicer, it is helpful to thaw the windshield
wiper blades. To thaw out the rear wiper blade, use the
