CAUTION
Do not modify the vehicle exhaust system,
brake system, or other systems when instal- ling a hitch or other trailer towing equipment. Do not use axle-mounted hitches as they
can cause damage to the axle housing, wheelbearings, wheels or tires.
WAGON including OUTBACK SPORT
The use of a genuine SUBARU trailer hitch is recom-
mended. A genuine SUBARU hitch is available from
your SUBARU dealer.
If use of a non-genuine hitch is unavoidable, be sure
the hitch is suited to your vehicle and trailer. Consult
with a professional hitch supplier to assist you in
choosing an appropriate hitch for your vehicle. Be
sure to follow all of the hitch manufacturer ’s instruc-
tions for installation and use.
Never use a hitch that mounts only to the rear bum-
per. The bumper is not designed to handle that typeof load.
For all types of hitches, regularly check that the
hitch mounting bolts and nuts are tight.
SEDAN
SUBARU does not offer accessory trailer hitches. Consult with a professional hitch supplier to assist
you in choosing an appropriate hitch for your ve-
hicle. Be sure to follow all of the hitch manufacturer
’s
instructions for installation and use.
Never use a hitch that mounts only to the rear bum-
per. The bumper is not designed to handle that type of load. Regularly check that the hitch mounting bolts and
nuts are tight.
Connecting a trailer
Trailer brakes
If your trailer ’s total weight (trailer weight plus its
cargo weight) exceeds 1,000 lbs (453 kg), the trailer
is required to be equipped with its own brake sys-
tem. Electric brakes or surge brakes are recom-
mended, and must be installed properly. Check thatyour trailer ’s brakes conform with Federal, state/
province and/or other applicable regulations. Your
SUBARU’ s brake system is not designed to be
tapped into the trailer ’s hydraulic brake system.
Please ask your SUBARU dealer and professional
trailer supplier for more information about the trail-er’ s brake system.

WARNING
Adequate size trailer brakes are required
when the trailer and its cargo exceed 1,000 lbs (453 kg) total weight. Do not directly connect your trailer ’s
hydraulic brake system to the hydraulic brake
system in your vehicle. Direct connectionwould cause the vehicle ’s brake performance
to deteriorate and could lead to an accident.
Trailer safety chains
In case the trailer hitch connector or hitch ball
should break or become disconnected, the trailer
could get loose and create a traffic safety hazard.
For safety, always connect the towing vehicle and
trailer with trailer safety chains. Pass the chains
crossing each other under the trailer tongue to pre-
vent the trailer from dropping onto the ground in
case the trailer tongue should disconnect from the
hitch ball. Allow sufficient slack in the chains taking
tight-turn situations into account; however, be care-
ful not to let them drag on the ground.
For more information about the safety chain connec-
tion, refer to the instructions for your hitch and trailer.
WARNING
Always use safety chains between your ve-
hicle and the trailer. Towing a trailer withoutsafety chains could create a traffic safety haz-ard if the trailer separates from the hitch due to coupling damage or hitch ball damage.
Side mirrors
After hitching a trailer to your vehicle, check that the
standard side mirrors provide a good rearward field of view without significant blind spots. If significant blind spots occur with the vehicle ’s standard side
mirrors, use towing mirrors that conform with Fed-

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.

If your vehicle has an automatic transmission,
avoid using the accelerator pedal to stay stationary on an uphill slope instead of using the parking brakeor foot brake. That may cause the transmission fluid
to overheat. Also, if your vehicle is equipped with an
automatic transmission, avoid driving with the gear selector lever in “D” when towing a heavy trailer to
prevent fluid overheating. A lower gear should be used.
Parking on a grade
Always block the wheels under both vehicle and
trailer when parking. Apply the parking brake firmly.
You should not park on a hill or slope. But if parking on a hill or slope cannot be avoided, you shouldtake the following steps:
1. Apply the brakes and hold the pedal down.
2. Have someone place wheel blocks under boththe vehicle and trailer wheels.
3. When the wheel blocks are in place, release the
regular brakes slowly until the blocks absorb theload.
4. Apply the regular brakes and then apply the
parking brake; slowly release the regular brakes.
5. Shift into 1st or reverse gear (manual transmis- sion) or “P” (automatic transmission) and shut off the
engine.

Appearance care

Exterior care Washing
The best way to preserve your vehicle ’s beauty is
frequent washing. Wash the vehicle at least once a
month to avoid contamination by road grime.
Wash dirt off with a wet sponge and plenty of luke-
warm or cold water. Do not wash the vehicle with hot
water and in direct sunlight.
Salt, chemicals, insects, tar, soot and bird droppings
should be washed off by using a light detergent, as
required. If you use a light detergent, make certain
that it is a neutral detergent. Do not use strong soap or chemical detergents. All cleaning agents should
be promptly flushed from the surface and not al-
lowed to dry there. Rinse the vehicle thoroughly with
plenty of lukewarm water. Wipe the remaining water
off with a chamois or soft cloth. NOTE When having your vehicle washed in an auto- matic car wash, make sure beforehand that thecar wash is of suitable type. If the vehicle is
equipped with a rear/roof spoiler or rear wiper, itmay be damaged by car wash brushes or otherequipment.
CAUTION
When washing the vehicle, the brakes may
get wet. As a result, the brake stopping dis-
tance will be longer. To dry the brakes, drivethe vehicle at a safe speed while lightly press- ing the brake pedal to heat up the brakes. Do not wash the engine compartment and
area adjacent to it. If water enters the engineair intake, electrical parts or the power steer-
ing fluid reservoir, it will cause engine trouble
or faulty power steering respectively.
Washing the underbody
Chemicals, salts and gravel used for deicing road
surfaces are extremely corrosive, accelerating the
corrosion of underbody components, such as theexhaust system, fuel and brake lines, brake cables,floor pan and fenders, and suspension.
Thoroughly flush the underbody and inside of the
fenders with lukewarm or cold water at frequent in-
tervals to reduce the harmful effects of such agents.
Using a warm water washer
Keep a good distance of 12 in (30 cm) or more
between the washer nozzle and the vehicle.

Replacement of brake pad and lining
The front disc brakes and the right rear disc brake have an audible wear indicators on the brake pads. If the brake pads wear close to their service limit,
the wear indicator makes a very audible scrapingnoise when the brake pedal is applied.
If you hear this scraping noise each time you apply the brake pedal, have the brake pads serviced byyour SUBARU dealer as soon as possible.
CAUTION
If you continue to drive despite the scraping noise from the audible brake pad wear indica-
tor, it will result in the need for costly brake rotor repair or replacement.
Breaking-in of new brake pads and linings
When replacing the brake pad or lining, use only
genuine SUBARU parts. After replacement, the new
parts must be broken in as follows:
Brake pad and lining
While maintaining a speed of 30 to 40 mph (50 to 65
km/h), step on the brake pedal lightly. Repeat this
five or more times.
Parking brake lining
1. Drive the vehicle at a speed of about 22 mph (35km/h).
2. With the parking brake release button pushed in,
pull the parking brake lever SLOWLY and GENTLY.
(Pulling with a force of approximately 33 lb [147 N,15 kg].)
3. Drive the vehicle for about 220 yards (200 me- ters) in this condition.
