Trailer hitches
Choose a proper hitch for your vehicle and trailer.
WARNING
Never drill the frame or under-body of your
vehicle to install a commercial trailer hitch. If you do, dangerous exhaust gas, water or mud may enter the passenger compartment
through the drilled hole. Exhaust gas containscarbon monoxide, a colorless and odorless
gas which is dangerous, or even lethal, if
inhaled. Also, drilling the frame or under-body of your vehicle could cause deterioration of strength of your vehicle and cause corrosionaround the drilled hole.
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.

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 trailer without safety chains could create a traffic safety haz-ard if the trailer separates from the hitch dueto coupling damage or hitch ball damage.

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 can result 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
safety’ s sake, you should employ extra cau-
tion when towing a trailer and you should
never speed. You should also keep the follow-ing tips in mind:
Before starting out on a trip
Check that the vehicle and vehicle-to-hitch mount-
ing are in good condition. If any problems are apparent, do not tow the trailer.
Check that the vehicle sits horizontally with the
trailer attached. If the vehicle is tipped sharply up at
the front and down at the rear, check the total trailer
weight, GVW, GAWs and tongue load again, then
confirm that the load and its distribution are accept- able. Check that the tire pressures are correct.
Check that the vehicle and trailer are connected
properly. Confirm that. –the trailer tongue is connected properly to the
hitch ball. – the trailer lights connector is connected prop-
erly and trailer ’s brake lights illuminate when the
vehicle’ s brake pedal is pressed, and that the trail-
er’ s turn signal lights flash when the vehicle ’s turn
signal lever is operated. – the safety chains are connected properly.
– all cargo in the trailer is secured safety in posi-
tion.– the side mirrors provide a good rearward field of
view without a significant blind spot.
Sufficient time should be taken to learn the “feel”
of the vehicle/trailer combination before starting out
on a trip. In an area free of traffic, practice turning, stopping and backing up.

Driving tips
8-36
Driving with a trailer
You should allow for considerably more stopping
distance when towing a trailer. Avoid sudden brak-
ing because it may result in skidding or jackknifing
and loss of control. Avoid abrupt starts and sudden accelerations. If
your vehicle has a manual transmission, always start
out in first gear and release the clutch at moderate
engine revolution. Avoid uneven steering, sharp turns and rapid lane
changes. Slow down before turning. Make a longer than
normal turning radius because the trailer wheels will
be closer than the vehicle wheels to the inside of the
turn. In a tight turn, the trailer could hit your vehicle. Crosswinds will adversely affect the handling of
your vehicle and trailer, causing sway. Crosswindscan be due to weather conditions or the passing of
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 yourvehicle. Backing up with a trailer is difficult and takes
practice. When backing up with a trailer, never accelerate or steer rapidly. When turning back, grip the 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.
OM-H2791
1) Left turn 2) 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 a automatic transmission, avoid
using the accelerator pedal to stay stationary on an
uphill slope instead of using the parking brake or
foot brake. That may cause the transmission fluid to
overheat. Also, if your vehicle is equipped with an
automatic transmission, avoid driving with the gearselector lever in “D” when towing a heavy trailer to
prevent fluid overheating.
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 parkingon 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.

Temporary spare tire (if equipped)
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 and may lead to an accident.
The temporary spare tire is smaller and lighter than
a conventional tire and is designed for emergency
use only. Remove the temporary spare tire and re-
install the conventional tire as soon as possible be-
cause the spare tire is designed only for temporary use.
Check the inflation pressure of the temporary spare
tire periodically to keep the tire ready for use. The
correct pressure is 60 psi (4.2 kg/cm2
, 420 kPa) .
When using the temporary spare tire, note the fol-lowing:
Do not exceed 50 mph (80 km/h).
Do not put a tire chain on the temporary spare tire.
Because of the smaller tire size, a tire chain will not
fit properly. Do not use two or more temporary spare tires at
the same time. Do not drive over obstacles. This tire has a smaller
diameter, so road clearance is reduced.
HG0106
1) Tread wear indicator bar
2) Indicator location mark
When the wear indicator appears on the tread, re-
place the tire.

In case of emergency

1) Spare fuse
2) FWD connector
NOTE
(If your vehicle is AWD with automatic transmis-
sion, except Turbo models) Before driving your
vehicle with the temporary spare tire, put a sparefuse inside the FWD connector in the main fusebox located in the engine compartment and con-firm that the Front-wheel drive warning light
“FWD” in the combination meter comes on. The
all wheel drive capability of the vehicle has now
deactivated. After re-installing the conventionaltire, remove the spare fuse from the FWD con-nector in order to reactivate all wheel drive.
CAUTION
Never use any temporary spare tire other than the original. Using other sizes may result in
severe mechanical damage to the drive train of your vehicle.
