1) Hitch ball installation point
2) Hooks for safety chains
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 part
of the vehicle other than the safety
chain hooks.

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

! 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
GAWscanbeadjustedbyrelocating
passengers and luggage inside the vehi-
cle. The front and rear GAWR are also
shown on the 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
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 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; 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 rightsides.
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 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 towingequipment.
. Do not use axle-mounted hitches
as they can cause damage to the
axle housing, wheel bearings,
wheels or tires.
Choose a proper hitch for your vehicle and
trailer.
The use of a genuine SUBARU trailer
hitch is recommended. A genuine
SUBARU hitch is available from your
SUBARU dealer.
If use of a non-genuine hitch is unavoid-
able, be sure the hitch is suited to your
vehicle and trailer. Consult with a profes-
sional hitch supplier to assist you in
choosing an appropriate hitch for your
vehicle. Be sure to follow all of the hitchmanufacturer ’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 aretight. Driving tips

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 brake lights and turn
signal lights each time you hitch up. ! 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.
The recommended cold tire pressure
under trailer towing conditions is shownin “Tires ”F 12-10 and in “GAS STATION
REFERENCE ”at the end of this manual.
Adjust the rear tire pressure to the
recommended pressure when the tires
are cold. Normal pressure should be
maintained in the front tires. Trailer tire condition, size, load rating and
proper inflation 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.

hitch mounting 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 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 con-
nected properly and trailer ’sbrake
lights illuminate when the vehicle ’s
brake pedal is pressed, and that the trailer ’s turn signal lights flash when
the vehicle ’s turn signal lever is oper-
ated. – the safety chains are connected
