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 ap-
propriate for your vehicle. In addition, be sure to follow
the instructions on correct installation and use provid-
ed by the trailer and other towing equipment manufac- turers.
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.
yAdequate size trailer brakes are required
when the trailer and its cargo exceed 1,000 lbs
(453 kg) total weight. y 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 acceptable.

TTongue 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. 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 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.

Driving tips
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.
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.
Choose a proper hitch for your vehicle and trailer.

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. 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,
use towing mirrors that conform with Federal, state/
province and/or other applicable regulations. T 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. T 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” 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 tipsyNever exceed 45 mph (72 km/h) when towing
a trailer in hilly country on hot days. y 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
