New vehicle break-in driving – the
first 1,000 miles (1,600 km)
The performance and long life of your vehicle are de-
pendent on how you handle and care for your vehicle
while it is new. Follow these instructions during the
first 1,000 miles (1,600 km):
Do not race the engine. And do not allow engine
speed to exceed 4,000 rpm except in an emergency. Do not drive at one constant engine or vehicle
speed for a long time, either fast or slow. Avoid starting suddenly and rapid acceleration, ex-
cept in an emergency. Avoid hard braking, except in an emergency.
The same break-in procedures should be applied to
an overhauled engine, newly mounted engine or when
brake pads or brake linings are replaced with new
ones.
Fuel economy hints
The following suggestions will help to save your fuel. Select the proper gear position for the speed and
road conditions. Avoid sudden acceleration or deceleration. Always
accelerate gently until you reach the desired speed.
Then try to maintain that speed for as long as possible. Do not pump the accelerator and avoid racing the
engine. Avoid unnecessary engine idling.
Keep the engine properly tuned.
Keep the tires inflated to the correct pressure shown
on the tire placard, which is located under the door
latch on the driver’s side. Low pressure will increase
tire wear and fuel consumption. Use the air conditioner only when necessary.
Keep the front and rear wheels in proper alignment.
Avoid carrying unnecessary cargo.

Engine exhaust gas (Carbon monox-
ide)
Never inhale engine exhaust gas. Engine ex-
haust gas contains carbon monoxide, a color-
less and odorless gas which is dangerous, or
even lethal, if inhaled. Always properly maintain the engine exhaust
system to prevent engine exhaust gas from en-
tering the vehicle. Never run the engine in a closed space, such
as a garage, except for the brief time needed to
drive the vehicle in or out of it. Avoid remaining in a parked vehicle for a
lengthy time while the engine is running. If that
is unavoidable, then use the ventilation fan to
force fresh air into the vehicle. Always keep the front ventilator inlet grille
free from snow, leaves or other obstructions to
ensure that the ventilation system always
works properly. If at any time you suspect that exhaust fumes
are entering the vehicle, have the problem
checked and corrected as soon as possible. If
you must drive under these conditions, drive only with all windows fully open.
Keep the rear gate closed while driving to
prevent exhaust gas from entering the vehicle.
NOTE
Due to the expansion and contraction of the met-
als used in the manufacture of the exhaust sys-
tem, you may hear a crackling sound coming from
the exhaust system for a short time after the en-
gine has been shut off. This sound is normal.

Driving tips
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
HS8003BA

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

equate measure of traction, handling and braking
performance in year-round driving. In winter, it may be
possible to enhance performance through use of tires
designed specifically for winter driving conditions.
When you choose to install winter tires on your vehi-
cle, be sure to use the correct tire size and type. You
must install four winter tires that are of the same size,
construction, brand and load range and you should
never mix radial, belted bias or bias tires since this
may result in dangerous handling characteristics.
When you choose a tire, make sure that there is
enough clearance between the tire and vehicle body.
Remember to drive with care at all times regardless of
the type of tires on your vehicle. Tire chains
Driving on snowy grades or icy roads may require the
use of tire chains, in which case put the chains on the
front wheels only. Use only SAE class S type chains
that are of the correct size for your tires so as not to
damage the vehicle body or suspension.
When driving with tire chains, drive at speeds below
19 mph (30 km/h).
Always use the utmost care when driving with tire
chains — overconfidence because you are driving
with tire chains could easily lead to a serious accident.
Rocking the vehicle
If you must rock the vehicle to free it from snow, 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 possible 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).
Refer to the “Automatic transmission” section in chap-
ter 7 for information on holding the transmission in 2nd
position.

Trailer towing
Your car is designed and intended to be used primarily
as a passenger-carrying vehicle. Towing a trailer puts
additional loads on your car’s engine, drivetrain,
brakes, tires and suspension and has an adverse ef-
fect on fuel economy.
If you do decide to tow a trailer, your safety and satis-
faction depend upon proper use of correct equipment
and cautious operation of your vehicle. Seek the ad-
vice of your SUBARU dealer to assist you in purchas-
ing a hitch and other necessary towing equipment
appropriate for your vehicle. In addition, be sure to fol-
low the instructions on correct installation and use pro-
vided by the trailer and other towing equipment manufacturers.
SUBARU assumes no responsibility for injuries or ve-
hicle damage that result from trailer towing equipment,
or from any errors or omissions in the instructions ac-
companying such equipment or for your failure to fol-
low the proper instructions. Warranties and maintenance
SUBARU warranties do not apply to vehicle damage
or malfunction caused by trailer towing. If you use your
vehicle to tow a trailer, more frequent maintenance will
be required due to the additional load. (Refer to “Main- tenance schedule under severe driving conditions” in
the “Warranty and Maintenance Booklet”.)
Under no circumstances should a trailer be towed with
a new vehicle or a vehicle with any new powertrain
component (engine, transmission, differential, wheel
bearings, etc.) for the first 1,000 miles (1,600 km) of
driving.
Maximum load limits
Never exceed the maximum load limits ex-
plained below. Exceeding the maximum load
limits could cause personal injury and/or vehi-
cle damage.
Adequate size trailer brakes are required
when the trailer and its cargo exceed 1,000 lbs
(453 kg) total weight. Before towing a trailer, check the trailer total
weight, GVW, GAWs and tongue load. Make
sure the load and its distribution in your vehicle
