TTongue load
Tongue load
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
SEDAN
SUBARU does not offer accessory trailer hitches.
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 bumper.
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
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.

Driving tips
y
Adequate size trailer brakes are required
when the trailer and its cargo exceed 1,000 lbs
(453 kg) total weight. y Do not directly connect your trailer’s hydrau-
lic brake system to the hydraulic brake system
in your vehicle. Direct connection would cause
the vehicle’s brake performance to deteriorate
and could lead to an accident.
T 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 cross-
ing each other under the trailer tongue to prevent 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 careful 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.
Always use safety chains between your vehicle
and the trailer. Towing a trailer without safety
chains could create a traffic safety hazard if the
trailer separates from the hitch due to coupling
damage or hitch ball damage.
T 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,

Driving tips
when towing a trailer and you should never
speed. You should also keep the following tips
in mind:
T Before starting out on a trip
y Check that the vehicle and vehicle-to-hitch mount-
ing are in good condition. If any problems are appar-
ent, do not tow the trailer. y Check that the vehicle sits horizontally with the trail-
er 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 con-
firm that the load and its distribution are acceptable.y Check that the tire pressures are correct.
y 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 properly
and trailer’s brake lights illuminate when the vehi-
cle’s brake pedal is pressed, and that the trailer’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 position.
– the side mirrors provide a good rearward field of view without a significant blind spot.
y 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. T Driving with a trailer
y You should allow for considerably more stopping
distance when towing a trailer. Avoid sudden braking
because it may result in skidding or jackknifing and
loss of control. y 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 en-
gine revolution. y Avoid uneven steering, sharp turns and rapid lane
changes. y Slow down before turning. Make a longer than nor-
mal 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. y Crosswinds will adversely affect the handling of
your vehicle and trailer, causing sway. Crosswinds
can be due to weather conditions or the passing of
large tracks or buses. If swaying occurs, firmly grip the
steering wheel and slow down immediately but gradu-
ally. y 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
y Backing up with a trailer is difficult and takes prac-
tice. 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. y 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 deal- er. T
Driving on grades
y 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 overheat-
ing of your vehicle’s brakes. Do not make sudden
downshifts.y When driving uphill in hot weather, the air condition-
er may turn off automatically to protect the engine from
overheating.y 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 relatively prone to
overheating under these conditions. If the water tem-
perature gauge pointer approaches the OVERHEAT
zone or the AT OIL TEMP warning light illuminates,
immediately switch off the air conditioner and stop the
vehicle at the nearest safe place. Refer to the “Engine
overheating” section in chapter 9, and “Warning and
indicator lights” section in chapter 3. y If your vehicle has an 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 over-
heat. Also, if your vehicle is equipped with an automat-
ic transmission, avoid driving with the gear selector le-
ver in “D” when towing a heavy trailer to prevent fluid

Maintenance and service
Use only those wheels that are specified for
your vehicle. Wheels not meeting specifica-
tions could interfere with brake caliper opera-
tion and may cause the tires to rub against the
wheel well housing during turns. The resulting
loss of vehicle control could lead to an acci-
dent.
NOTE
When any of the wheels is removed and replaced
for tire rotation or to change a flat tire, alwayscheck the tightness of the wheel nuts after driving
approximately 600 miles (1,000 km). If any nut is
loose, tighten it to the specified torque.
Aluminum wheels
Aluminum wheels can be scratched and damaged
easily. Handle them carefully to maintain their appear-
ance, performance, and safety. y
When any of the wheels is removed and replaced
for tire rotation or to change a flat, always check the
tightness of the wheel nuts after driving approximately
600 miles (1,000 km). If any nut is loose, tighten it to
the specified torque.y Never apply oil to the threaded parts, wheel nuts, or
tapered surface of the wheel.y Never let the wheel rub against sharp protrusions or
curbs. y Be sure to fit tire chains on uniformly and completely
around the tire, otherwise the chains may scratch the
wheel.y When wheel nuts, balance weights, or the center
cap is replaced, be sure to replace them with genuine
SUBARU parts designed for aluminum wheels.
