Driving tips/Trailer hitch (dealer option)
!Installing carrying attachments on
the crossbars
When installing any carrying attachment
such as a bike carrier, ski carrier, kayak
carrier, cargo basket, etc. on the cross-
bars, follow the manufacturer ’s instruc-
tions and make sure that the attachment is
securely fixed to the crossbars. Use only
attachments designed specifically for the
crossbars. A set of the crossbars is
designed to carry loads (cargo and attach-
ment) of not more than 165 lbs (75 kg).
Before operating the vehicle, make sure
that the cargo is properly secured on the
attachment.
NOTE
Remember that the vehicle ’s center of
gravity is altered with the weight of the
load on the roof, thus affecting the
driving characteristics.
Drive carefully. Avoid rapid starts, hard
cornering and abrupt stops. Crosswind
effects will be increased. !
Removal and installation of the
crossbars
Each of the two roof moldings has two
mounting points for crossbars. Each
mounting point is fitted with a cover. Use
a screwdriver to remove the covers. When
installing the crossbars on the roof mold-
ing, follow the manufacturer ’s instructions.
Trailer hitch (dealer option)
WARNING
. Never exceed the maximum
weight specified for the trailer
hitch. Exceeding the maximum
weight could cause an accident
resulting in serious personal in-
juries. Permissible trailer weight
changes depending on the situa-
tion. For possible recommenda-
tions and limitations, refer to
“ Trailer towing” F8-19.
. 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 max-
imum gross weight. Towing trai-
lers without safety chains could
create a traffic safety hazard if
the trailer separates from the
hitch due to coupling damage or
hitch ball damage.
. Be sure to check the hitch pin
and safety pin for positive lock-
ing placement before towing a
trailer. If the ball mount comes off
the hitch receiver, the trailer
could get loose and create a
8-16

traffic safety hazard.
. Although towing regulations for
trailer or caravan vehicles vary
by state/region, all regulations
agree that specifications such
as the maximum gross trailer
weight must not exceed the les-
ser of the following:
– Maximum gross trailer weight
– Maximum gross tongue
weight
– GVWR
– GAWR
. Failure to comply with the proce-
dures set forth will not only
compromise your safety, but will
also negate your insurance cov-
erage and/or may violate the
state road and traffic acts and
regulations.
. 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
distributing hitch.
. The standard bumper beam must
be installed after you remove the
trailer hitch. Consult a SUBARU
dealer for purchase of a standard
bumper beam if you do not have the original.
. Safety performance is decreased
and there is increased risk of
injury to passengers in the case
of an accident if the trailer hitch
or a standard bumper beam is
not installed. One of them must
always be installed on the vehi-
cle.
. If a trailer hitch is installed, it is
not possible to install the rear
towing hook.
When towing a trailer, refer to “Trailer
towing ”F 8-19.& Connecting a trailer

5. Use only a hitch ball that is appropriate
for the ball mount and your trailer. The
hitch ball must be securely installed on the
ball mount.
6. Connect your trailer to the hitch ball.
7. Connect the trailer and the hitch with
safety chains that will hold the trailer’s maximum gross weight. The chains
should cross under the trailer tongue to
prevent the tongue from dropping onto the
ground in case it 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.
WARNING
Do not connect safety chains to any
part of the vehicle other than the
safety chain hooks.

8. Connect the hitch electrical wire har-
ness
’s black four-pin electrical wire con-
nector to the towing trailer ’s wire harness. 9. Confirm proper function of the hitch
electrical wire harness by individually
activating the brake, stop and turn signal
lights on the trailer.
NOTE
Always disconnect the trailer electrical
wire harness before launching or re-
trieving a watercraft.
&
If not towing a trailer
. Remove the ball mount from the hitch
receiver tube.

Trailer towing
Your vehicle is designed and intended to
be used primarily as a passenger-carrying
vehicle. Towing a trailer puts additional
loads on your vehicle’s engine, drivetrain,
brakes, tires and suspension and has an
adverse effect on fuel economy.
If you do decide to tow a trailer, your safety
and satisfaction depend upon proper use
of correct equipment and cautious opera-
tion of your vehicle. Seek the advice of
your SUBARU dealer to assist you in
purchasing a hitch and other necessary
towing equipment appropriate for your
vehicle. Do not use towing equipment
other than genuine SUBARU towing
equipment. In addition, be sure to follow
the instructions on correct installation and
use provided by SUBARU.
SUBARU assumes no responsibility for
injuries or vehicle damage that result from
trailer towing equipment, or from any
errors or omissions in the instructions
accompanying such equipment or for your
failure to follow the proper instructions.
Regularly check that the hitch mounting
bolts and nuts are tightened securely.
& 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 “Maintenance 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 (en-
gine, transmission, differential, wheel
bearings, etc.) for the first 1,000 miles
(1,600 km) of driving.
& Maximum load limits
WARNING
Never exceed the maximum load
limits explained in the following.
Exceeding the maximum load limits
could cause personal injury and/or
vehicle damage.
CAUTION
. Adequate size trailer brakes are
required when the trailer and its
cargo exceed 1,000 lbs (453 kg) total weight.
. Before towing a trailer, check the
trailer total weight, GVW, GAWs
and tongue load. Make sure the
load and its distribution in your
vehicle and trailer are accepta-
ble.
! Total trailer weight
Total trailer weight
The total trailer weight (trailer weight plus
its cargo load) must never exceed the
maximum weight in the following table.

Driving tips/Trailer towing
!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.
Certification label
GVWR is shown on the certification label
located at the bottom of the driver ’s side
door pillar of your vehicle. !
Gross Axle Weight (GAW) and
Gross Axle Weight Rating (GAWR)Gross Axle Weight
The total weight applied to each axle
(GAW) must never exceed the Gross Axle
Weight Rating (GAWR). The front and rear
GAWs can be adjusted by relocating
passengers and luggage inside the vehi-
cle. The front and rear GAWR are also
shown on the certification label located at
the bottom of driver ’s side door pillar.
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
8-20

while driving.
!Tongue load
Tongue load
Ensure that the trailer tongue load is from
8 to 11 percent 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 illustration
above. When weighing the tongue load,
be sure to position the towing coupler 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; approximately
60 percent of the trailer load should be in
the front and approximately 40 percent in
the rear. Also, distribute 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.
WARNING
If the trailer is loaded with more
weight in the back of trailer ’s axle
than in the front, the load is taken off

Driving tips/Trailer towing
the rear axle of the towing vehicle.
This may cause the rear wheels to
skid, especially during braking or
when vehicle speed is reduced dur-
ing cornering, resulting in over-
steer, spin out and/or jackknifing.
&Trailer hitches
WARNING
Never drill the frame or under-body
of your vehicle to install a commer-
cial trailer hitch. If you do, danger-
ous exhaust gas, water or mud may
enter the passenger compartment
through the drilled hole. Exhaust
gas contains carbon 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 corrosion around
the drilled hole.
CAUTION
. Do not modify the vehicle ex-
haust 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 bearings,
wheels or tires.
Do not use a trailer hitch other than a
genuine SUBARU trailer hitch. A genuine
SUBARU hitch is available from your
SUBARU dealer.
& Connecting a trailer
! Trailer brakes
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 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 required to be
equipped with its own brake system.
Electric 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.
! Trailer safety chains
WARNING
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 discon-
nected, the trailer could get loose and
create a traffic safety hazard.
For safety, always connect the towing
vehicle and trailer with trailer safety
chains. Two chains should be used in
8-22

total, one to the right side and the other to
the left side trailer tongue. Pass the chains
crossing 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.
!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 stan-
dard side mirrors, use towing mirrors that
conform with Federal, state/province and/
or other applicable regulations. !
Trailer lights
CAUTION
Direct splicing or other improper
connection of trailer lights may
damage your vehicle’ s electrical
system and cause a malfunction of
your vehicle ’s lighting system.
Connection of trailer lights to your vehi-
cle ’s electrical system requires modifica-
tions to the vehicle ’s lighting circuit to
increase its capacity and accommodate
wiring changes. To ensure the trailer lights
are connected properly, please consult
your SUBARU dealer. Check for proper
operation of the turn signals and the brake
lights each time you connect a trailer to
your vehicle.
! Tires
WARNING
Never tow a trailer when the tem-
porary spare tire is used. The tem-
porary spare tire is not designed 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. Refer to
“Tires”F 12-
10.
Trailer tire condition, size, load rating and
proper inflation pressure should be in
accordance with the trailer manufacturer ’s
specifications. Also check federal, state,
province and/or other applicable regula-
tions.
In the event your vehicle gets a flat tire
when towing a trailer, ask a commercial
road service representative or profes-
sional 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.
