Trailer hitch (if equipped)
The trailer hitch is designed to tow a Class 1 rated
load.
When you tow a trailer, follow the instructions in the
next section “Trailer towing”.

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 next section “Trailer towing” for pos-
sible recommendations and limitations. 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

er tube so that the pin passes through the ball mount.
3. Insert the safety pin securely into the hitch pin.
4. Pull the ball mount to make sure it does not come
off the hitch receiver. 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 ac-
count; however, be careful not to let them drag on the

Do not connect safety chains to part of the ve-
hicle other than the safety chain hooks.
Hitch harness connector
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, 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
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 fou-pin connector of the
hitch wire harness to protect against possible damage. Occasionally lubricate terminals of the four-pin con-
nector using terminal grease.

Trailer towing
Your car is designed and intended to be used primarily
as a passenger-carrying vehicle. Towing a trailer puts
additional loads on your car’s engine, drivetrain,
brakes, tires and suspension and has an adverse ef-
fect 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
appropriate for your vehicle. In addition, be sure to fol-
low the instructions on correct installation and use pro-
vided by the trailer and other towing equipment manufacturers.
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.
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

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 plate located on
the driver’s side door jamb.

Gross Axle Weight (GAW) and Gross Axle
Weight Rating (GAWR)
GrossAxleWeight
The total weight applied to each axle (GAW) must nev-
er exceed the Gross Axle Weight Rating (GAWR). The
front and rear GAWs can be adjusted by relocating
passengers and luggage inside the vehicle. The front
and rear GAWR are also shown on the certification
plate.
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 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 illustration above. 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 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.

Connecting a trailer
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 infor-
mation about the trailer’s brake system.
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
