New vehicle break-in driving –
the first 1,000 miles (1,600 km)
The performance and long life of your vehicle are
dependent on how you handle and care for your ve-
hicle while it is new. Follow these instructions duringthe 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 emergen-
cy. Do not drive at one constant engine or vehicle
speed for a long time, either fast or slow. Avoid starting suddenly and rapid acceleration,
except 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 withnew 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. Al-
ways accelerate gently until you reach the desired
speed. Then try to maintain that speed for as longas 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 align-
ment. Avoid carrying unnecessary luggage or cargo.

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 re-
paired by an authorized SUBARU dealer. Do not apply undercoating or rust prevention
treatment to the heat shield of catalytic converter and the exhaust system.
WARNING
Avoid fire hazards. Do not drive or park the
vehicle anywhere near flammable materials
(e.g. grass, paper, rags or leaves), becausethe catalytic converter operates at very hightemperatures. Keep everyone and flammable materials
away from the exhaust pipe while the engine is running. The exhaust gas is very hot. Periodic inspections
To keep your vehicle in the best condition at all
times, always have the recommended maintenance
services listed in the maintenance schedule in the“
Warranty and Maintenance Booklet ” performed at
the specified time or mileage intervals.

Off road driving
WARNING
Always maintain a safe driving speed ac-
cording to the road and weather conditions in order to avoid having an accident on a sharpturn, during sudden braking or under othersimilar conditions. Always use the utmost care in driving –
overconfidence because you are driving an allwheel drive vehicle could easily lead to a seri-ous accident.
All AWD models except OUTBACK SPORT
Your AWD vehicle is neither a conventional off-road
vehicle nor an all terrain vehicle. It is a passenger
car designed primarily for on-road use. The AWD
feature gives it some limited off-road capabilities in
situation in which driving surfaces a relatively level,
obstruction-free and otherwise similar to on-road driving conditions. Operating it under other than those conditions could subject the vehicle to exces-
sive stress which might result in damage not eligible for repair under warranty. If you do take your
SUBARU off road, you should review the common
sense precautions in the next section (applicable to
the OUTBACK SPORT) for general guidance. Butplease keep in mind that your vehicle
’s off-road ca-
pabilities are more limited than those of the OUT-
BACK SPORT.
Never attempt 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. OUTBACK SPORT
Because of the AWD feature and higher ground
clearance, 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
conventional off-road vehicle nor an all-terrain ve-
hicle. 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
towing rope or chain, a shovel, wheel blocks, first

WARNING
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 win-
dow. If the wiper blades are frozen to the windshield
or rear window, use the defroster with the airflow
control dial in the “t ” position and the temperature
control 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 rear window defogger.
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 controldial in “t ” and the temperature control dial set for
maximum warmth. After the windshield gets warmed
enough to melt the frozen snow on it, wash it away
using the windshield washer.
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 car at road side, use the
hazard warning flasher to alert other drivers.
We recommend use of non-freezing type wiper blades (winter blades) during the seasons you
could have snow and sub-zero temperatures.
Blades of this type give superior wiping perfor-
mance in snowy conditions. Be sure to use blades
that are suitable for your vehicle.
Corrosion protection
Refer to the “Corrosion protection ” section (chapter
10). Snow tires
WARNING
When replacing original tires with winter
(snow) tires, make sure you use only the same size, construction and load range as the origi-nal tires listed on the tire placard. Using other
sizes and construction may affect speedome-ter/odometer calibration and clearance be-tween the body and tires. It also may be dan-

eral, state/province and/or other applicable regula- tions.
Trailer lights
Connection of trailer lights to your vehicle ’s electrical
system requires modifications to the vehicle ’s light-
ing circuit to increase its capacity and accommo-
date wiring changes. To ensure the trailer lights are
connected properly, please consult your SUBARU
dealer. Check for proper operation of the turn sig-nals, the brake lights and parking lights each timeyou hitch up.
CAUTION
Direct splicing or other improper connection
of trailer lights may damage your vehicle ’s
electrical system and cause a malfunction ofyour vehicle ’s lighting system.
Tires
Make sure that all the tires on your vehicle are prop-
erly inflated to the pressure specified on the tire
placard located on the left center pillar of your ve-hicle.
Trailer tire condition, size, load rating and proper
inflation pressure should be in accordance with the trailer manufacturer
’s specifications.
In the event your vehicle gets a flat tire when towing
a trailer, ask a commercial road service to repair the
flat tire.
If you carry a regular size spare tire in your vehicle
or trailer as a precaution against getting a flat tire,
be sure that the spare tire is firmly secured.
WARNING
Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not
designed to sustain the towing load. Use ofthe temporary spare tire when towing canresult in failure of the spare tire and/or less
stability of the vehicle.
Trailer towing tips
CAUTION
Never exceed 45 mph (72 km/h) when tow-
ing a trailer in hilly country on hot days. When towing a trailer, steering, stability,
stopping distance and braking performancewill be different from normal operation. For

large trucks or buses. If swaying occurs, firmly grip the steering wheel and slow down immediately but
gradually.When passing other vehicles, considerable dis-
tance is required because of the added weight and
length caused by attaching the trailer to your vehicle.
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, gripthe 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 the nearest
SUBARU dealer.
Driving on grades
Before going down a steep hill, slow down and
shift into lower gear (if necessary, use 1st gear) in
order to utilize the engine braking effect and prevent
overheating of your vehicle ’s brakes. Do not make
sudden downshifts. When driving uphill in hot weather, the air condi-
tioner may turn off automatically to protect the
engine from overheating. When driving uphill in hot weather, pay attention to
the water temperature gauge pointer (for all
vehicles) and AT OIL TEMP warning light (for AT
vehicles) since the engine and transmission are rel-
atively prone to overheating under these conditions.
If the water temperature gauge pointer approaches
the OVERHEAT zone or the AT OIL TEMP warning
light illuminates, immediately switch off the air condi-
tioner and stop the vehicle at the nearest safe place.Refer to the “Engine overheat ” section in chapter 9,
and “Warning and indicator lights ” section in chap-
ter 3.

Be sure the jumper cables and clamps on
them do not have loose or missing insulation.
Do not jump start unless cables in suitablecondition are available. A running engine can be dangerous. Keep
your fingers, hands, clothing, hair and tools away from the cooling fan, belts and any other
moving engine parts. Removing rings,watches and ties is advisable.
When your vehicle does not start due to a run down
(discharged) battery, the vehicle may be jump
started by connecting your battery to another bat-
tery (called the booster battery) with jumper cables.
Jump starting is dangerous if it done incorrectly. If
you are unsure about the proper procedure for jump
starting, consult a competent mechanic.
How to jump start
1. Make sure the booster battery is 12 volts and the
negative terminal is grounded.
2. If the booster battery is in another vehicle, do notlet the two vehicles touch.
3. Turn off all unnecessary lights and accessories.
4. Connect the jumper cables exactly in the se-
quence illustrated.

Appearance care

Corrosion protection
Your SUBARU has been designed and built to resist
corrosion. Special materials and protective finishes
have been used on most parts of the vehicle to help
maintain fine appearance, strength, and reliable op- eration. Most common causes of corrosion
The most common causes of corrosion are:
1. The accumulation of moisture retaining dirt and
debris in body panel sections, cavities, and other
areas.
2. Damage to paint and other protective coatings caused by gravel and stone chips or minor acci- dents.
Corrosion is accelerated on the vehicle when:
1. It is exposed to road salt or dust control chemi-
cals, or used in coastal areas where there is more
salt in the air, or in areas where there is considerable industrial pollution.
2. It is driven in areas of high humidity, especially
when temperatures range just above freezing.
3. Dampness in certain parts of the vehicle remains
for a long time, even though other parts of the ve-
hicle may be dry. 4. High temperatures will cause corrosion to parts
of the vehicle which cannot dry quickly due to lack
of proper ventilation.
To help prevent corrosion
Wash the vehicle frequently. If you drive on salted
roads in the winter or if you live in a coastal area,
you should flush the underbody with fresh water fre-
quently.
After the winter has ended, it is recommended that
the underbody be given a very thorough washing.
Before the beginning of winter, check the condition of underbody components, such as the exhaust sys- tem, fuel and brake lines, brake cables, suspension, steering system, floor pan, and fenders. If any of
them are found to be rusted, they should be given
an appropriate rust prevention treatment or should
be replaced. Contact your SUBARU dealer to per-
form this kind of maintenance and treatment if you need assistance. Repair chips and scratches in the paint as soon as you find them.
Check the interior of the vehicle for water and dirt
accumulation under the floor mats because that
could cause corrosion. Occasionally check under
