1. Before placing the crossbar on the roof rails, make
sure that the T-30 torx® head screw is removed from
the top of each crossbar end support.
2. Rotate the lower clamp on the bottom of each end
support downward approximately 90 °.
3. With the front direction arrow label on the top right
side of the crossbar pointing toward the front of the ve-
hicle, carefully place the crossbar across the top of the
vehicle so that the crossbar end supports rest on the
top of the roof rails approximately 3 inches (76 mm)
rearward from the seam (joint) between the front roof
rail support and the roof rail.
4. Rotate (raise) the lower clamp up to the bottom of
the roof rail and loosely tighten the T-30 torx® head
screw with the torx® wrench provided, through the top
of the end support and into the threaded insert in the
lower clamp on each end of the crossbar.NOTE
It may be necessary to squeeze the lower clamp
and the end support together to compress the
pads and gain a better alignment of the pieces
while trying to start the screw. Use care not to
crossthread the screw in the insert.
5. Adjust the alignment of the crossbar on the roof
rails, and if available, use a T-30 torx® bit and torque
wrench and tighten the T-30 torx® head screws to 30
to 35 lbf·in (3.4 to 4.0 N·m, 0.35 to 0.41 kgf·m) of
torque (or tighten securely with the torx® wrench pro-
vided).

Trailer hitch (if equipped)
The trailer hitch is designed to tow a Class 1 rated
load. A maximum of 2,000 lbs (906 kg) gross trailer
weight and a maximum of 200 lbs (90 kg) gross
tongue weight are permissible for the trailer hitch.
When you tow a trailer, follow the instructions in the
section “Trailer towing” in this chapter.
y Never exceed the maximum weight specified
for the trailer hitch. Exceeding the maximum
weight could cause an accident resulting in se-
rious personal injuries. Permissible trailer
weight changes depending on the situation. Re-
fer to the section “Trailer towing” in this chap-
ter for possible recommendations and limita- tions.y Trailer brakes are required when the towing
load exceeds 1,000 lbs (453 kg). Be sure your
trailer has safety chains and that each chain
will hold the trailer’s maximum gross weight.
Towing trailers without safety chains could cre-
ate a traffic safety hazard if the trailer separates
from the hitch due to coupling damage or hitch
ball damage. y
Be sure to check the hitch pin and safety pin
for positive locking placement before towing a
trailer. If the ball mount comes off the hitch re-
ceiver, the trailer could get loose and create a
traffic safety hazard.y Use only the ball mount supplied with this
hitch. Use the hitch only as a weight carrying
hitch. Do not use with any type of weight dis-
tributing hitch.
„ Connecting a trailer
1. Remove the receiver cover from the hitch receiver
tube. Then insert the ball mount into the hitch receiver
tube.

wire connector to the towing trailer’s wire harness
9. Confirm proper function of the hitch wire harness
by individually activating the brake, right turn signal,
left turn signal, stop, and parking lights on the trailer.
NOTE
Always disconnect the trailer wire harness before
launching or retrieving a watercraft. „ When you do not tow a trailer
y Remove the ball mount from the hitch receiver tube and insert the receiver cover onto the hitch receiver tube.y
Place the dust cap over the four-pin connector of the
hitch wire harness to protect against possible damage.y Occasionally lubricate terminals of the four-pin con-
nector using terminal grease.

Trailer towing
Your vehicle is designed and intended to be used pri-
marily as a passenger-carrying vehicle. Towing a trail-
er puts additional loads on your vehicle’s engine, driv-
etrain, brakes, tires and suspension and has an ad-
verse effect 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 ap-
propriate for your vehicle. In addition, be sure to follow
the instructions on correct installation and use provid-
ed by the trailer and other towing equipment manufac-
turers.
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.
yAdequate size trailer brakes are required
when the trailer and its cargo exceed 1,000 lbs
(453 kg) total weight. y Before towing a trailer, check the trailer total
weight, GVW, GAWs and tongue load. Make
sure the load and its distribution in your vehicle

Ensure that the trailer tongue load is from 8 to 11 per-
cent of the total trailer weight and does not exceed the
maximum value of 200 lbs (90 kg). 1) Jack
2) Bathroom scale
The tongue load can be weighed with a bathroom
scale as shown in the following illustration. When
weighing the tongue load, be sure to position the tow-
ing coupler at the height at which it would be during ac-
tual towing, using a jack as shown.

Driving tips
F: Front of vehicle
The tongue load can be adjusted by proper distribution
of the load in the trailer. Never load the trailer with
more weight in the back than in the front; approximate-
ly 60 percent of the trailer load should be in the front
and approximately 40 percent in the rear. Also, distrib-
ute the load as evenly as possible on both the left and
right sides.
Be sure that all cargo is firmly secured to prevent a
change in weight distribution while driving.
If the trailer is loaded with more weight in the back of trailer’s axle than in the front, the load
is taken off the rear axle of the towing vehicle.
This may cause the rear wheels to skid, espe-
cially during braking or when vehicle speed is
reduced during cornering, resulting in over-
steer, spin out and/or jackknifing.
„ Trailer hitches
Choose a proper hitch for your vehicle and trailer.
Never drill the frame or under-body of your ve-
hicle 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 contains carbon mon-
oxide, a colorless and odorless gas which is
dangerous, or even lethal, if inhaled. Also, drill-
ing the frame or under-body of your vehicle
could cause deterioration of strength of your
vehicle and cause corrosion around the drilled
hole.

yDo not modify the vehicle exhaust system,
brake system, or other systems when installing
a hitch or other trailer towing equipment. y Do not use axle-mounted hitches as they can
cause damage to the axle housing, wheel bear-
ings, wheels or tires.
T 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 instructions for
installation and use.
Never use a hitch that mounts only to the rear bumper.
The bumper is not designed to handle that type of
load.
For all types of hitches, regularly check that the hitch
mounting bolts and nuts are tight. T

T Trailer brakes
If your trailer’s total weight (trailer weight plus its cargo
weight) exceeds 1,000 lbs (453 kg), the trailer is re-
quired to be equipped with its own brake system. Elec-
tric brakes or surge brakes are recommended, and
must be installed properly. Check that your 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 trailer’s brake system.
