!Gross Vehicle Weight (GVW) and Gross Vehicle
Weight Rating (GVWR)
Gross Vehicle Weight
The Gross Vehicle Weight (GVW) must never exceed
the Gross Vehicle Weight Rating (GVWR).
Gross Vehicle Weight (GVW) is the combined total of
the weight of the vehicle, driver, passengers, luggage,
trailer hitch, trailer tongue load and any other optional
equipment installed on your vehicle. Therefore, the
GVW changes depending on the situation. Determine
the GVW each time before going on a trip by putting
your vehicle and trailer on a vehicle scale.
GVWR is shown on the certification label located on

Certification label
To check both GVWR and GAWR and to confirm that
the total weight and weight distribution are within safe
driving limits, you should have your vehicle and trailer
weighed at a commercial weighing station.
Be sure that all cargo is firmly secured to prevent a
change in weight distribution while driving. !
Tongue load
Tongue load
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.

Driving tips
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).
A) Jack
B) Bathroom scale
The tongue load can be weighed with a bathroom
scale as shown in the illustration below. When weigh-
ing the tongue load, be sure to position the towing cou-
pler at the height at which it would be during actual
towing, using a jack as shown. F: Front
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.

!Trailer hitches
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.
"Do not modify the vehicle exhaust system,
brake system, or other systems when installing
a hitch or other trailer towing equipment. " Do not use axle-mounted hitches as they can
cause damage to the axle housing, wheel bear-
ings, wheels or tires.
Choose a proper hitch for your vehicle and trailer. !
OUTBACK wagon
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. ! All vehicles except OUTBACK wagon
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 nutsare tight.

Connecting a trailer
! Trailer brakes
"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 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.
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 infor-
mation about the trailer’s brake system. !
Trailer safety chains
Always use safety chains between your vehicle
and the trailer. Towing 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.
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.

!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 Federal, state/
province and/or other applicable regulations. ! Trailer lights
Direct splicing or other improper connection of
trailer lights may damage your vehicle’s electri- cal system and cause a malfunction of your ve-
hicle’s lighting system.
Connection of trailer lights to your vehicle’s electrical
system requires modifications to the vehicle’s lighting
circuit to increase its capacity and accommodate wir-
ing changes. To ensure the trailer lights are connected
properly, please consult your SUBARU dealer. Check
for proper operation of the turn signals, the brake
lights and parking lights each time you hitch up. ! Tires
Never tow a trailer when the temporary spare
tire is used. The temporary spare tire is not de-
signed to sustain the towing load. Use of the
temporary spare tire when towing can result in
failure of the spare tire and/or less stability of
the vehicle.
Make sure that all the tires on your vehicle are properly
inflated.
The recommended cold tire pressure under trailer tow-
ing conditions is shown in chapter 12, “Specifications”
UB8501BA

Driving tips
and in “GAS STATION REFERENCE” at the end of
this manual. Adjust the rear tire pressure to the recom-
mended pressure when the tires are cold. Normal
pressure should be maintained in the front tires.
Trailer tire condition, size, load rating and proper infla-
tion 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. !
Trailer towing tips
"Never exceed 45 mph (72 km/h) when towing
a trailer in hilly country on hot days. " When towing a trailer, steering, stability,
stopping distance and braking performance
will be different from normal operation. For
safety’s sake, you should employ extra caution
when towing a trailer and you should never speed. You should also keep the following 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 appar-
ent, do not tow the trailer." 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. " 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 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.

"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 with a trailer
" 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." 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. " Avoid uneven steering, sharp turns and rapid lane
changes. " 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. " 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 trucks or buses. If swaying occurs, firmly grip the
steering wheel and slow down immediately but gradu-
ally. " When passing other vehicles, considerable dis-
tance is required because of the added weight and length caused by attaching the trailer to your vehicle.
A) Left turn
B) Right turn
" 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. " 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.

Temporary spare tire
"Never tow a trailer when the temporary spare
tire is used. The temporary spare tire is not de-
signed to sustain the towing load. Use of the
temporary spare tire when towing can result in
failure of the spare tire and/or less stability of
the vehicle and may lead to an accident. " When a spare tire is mounted or a wheel rim
is replaced without the original pressure sen-
sor/transmitter being transferred, the low tire
pressure warning light will flash. This indicates
the tire pressure monitoring system (TPMS) is
unable to monitor all four road wheels. Contact
your SUBARU dealer as soon as possible for
tire and sensor replacement and/or system re-
setting.
Never use any temporary spare tire other than
the original. Using other sizes may result in se-
vere mechanical damage to the drive train of
your vehicle.
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 because 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 cor-
rect pressure is 60 psi (420 kPa, 4.2 kgf/cm 2
).
When using the temporary spare tire, note the follow-
ing: " 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.
