WARNING
When you carry something inside the ve-
hicle, secure it whenever you can to prevent it from being thrown around inside the vehicleduring sudden stops, sharp turns or in an ac- cident. Do not pile heavy loads on the roof. These
loads raise the vehicle ’s center of gravity and
make it more prone to tip over. Secure lengthy items properly to prevent
them from shooting forward and causing seri- ous injury during a sudden stop. Never exceed the maximum load limit. If you
do, some parts on your vehicle can break, or itcan change the way your vehicle handles.This could result in loss of control and cause
personal injury. Also, overloading can shorten the life of your vehicle. Do not place anything on the rear shelf
behind the rear seatback (for sedan) or the ex-
tended luggage cover (for wagon). Such itemscould tumble forward in the event of a suddenstop or a collision. This could cause serious
injury.
CAUTION
Do not carry spray cans, containers with flam- mable or corrosive liquids or any other dan- gerous items inside the vehicle.
NOTE
For better fuel economy, do not carry unneeded cargo. Vehicle capacity weight

checked, and retightened if necessary to 35 inch
lbs. (4.0 N-m, 0.41 kg-m), as outlined in Step #5above. Trailer hitch (if equipped) The trailer hitch is designed to tow a Class 1 rated
load. A maximum of
2,000 lbs. (906 kg) gross trailer
weight and a maximum of 200 lbs. (90 kg) gross
tongue weight are permissible for the trailer hitch.
When you tow a trailer, follow the instructions in the next section “Trailer towing ”.
WARNING
Never exceed the maximum weight specified
for the trailer hitch. Exceeding the maximum weight could cause an accident resulting inserious personal injuries. Permissible trailerweight changes depending on the situation.Refer to the next section “Trailer towing ” for
possible recommendations and limitations. Trailer brakes are required when the towing
load exceeds 1,000 lbs. (453 kg). Be sure yourtrailer has safety chains and that each chainwill hold the trailer ’s maximum gross weight.
Towing trailers without safety chains could create a traffic safety hazard if the trailer sepa- rates from the hitch due to coupling damageor hitch ball damage. Be sure to check the hitch pin and safety pin

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 safetychains 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.

Trailer towing
Your car is designed and intended to be used pri-
marily as a passenger-carrying vehicle. Towing a
trailer puts additional loads on your car ’s engine, dri-
vetrain, brakes, tires and suspension and has an
adverse effect on fuel economy.
If you do decide to tow a trailer, your safety and sat-
isfaction depend upon proper use of correct equip-
ment and cautious operation of your vehicle. Seekthe advice of your SUBARU dealer to assist you in
purchasing a hitch and other necessary towing
equipment appropriate for your vehicle. In addition,
be sure to follow the instructions on correct installa-
tion and use provided by the trailer and other towing
equipment manufacturers.
SUBARU assumes no responsibility for injuries or
vehicle damage that result from trailer towing equip-
ment, or from any errors or omissions in the instruc- tions accompanying such equipment or for your fail-
ure to follow 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 mainte-
nance will be required due to the additional load. (Refer to
“Maintenance schedule under severe driv-
ing conditions ” in the “Warranty and Maintenance
Booklet”.)
Under no circumstances should a trailer be towedwith a new vehicle or a vehicle with any new power-
train component (engine, 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 ex-
plained below. Exceeding the maximum loadlimits could cause personal injury and/or ve-hicle 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 acceptable.

Driving tips

F) Front of vehicle
The tongue load can be adjusted by proper distribu-
tion 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 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.
Trailer hitches
Choose a proper hitch for your vehicle and trailer.
WARNING
Never drill the frame or under-body of your
vehicle to install a commercial trailer hitch. If you do, dangerous exhaust gas, water or mudmay enter the passenger compartment
through the drilled hole. Exhaust gas containscarbon 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 ofstrength of your vehicle and cause corrosionaround the drilled hole.

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 connectionwould cause the vehicle ’s brake performance
to deteriorate and could lead to an accident.
Trailer safety chains
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
crossing each other under the trailer tongue to pre-
vent 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 care-
ful 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.
WARNING
Always use safety chains between your ve-
hicle and the trailer. Towing a trailer withoutsafety chains could create a traffic safety haz-ard if the trailer separates from the hitch due to coupling damage or hitch ball damage.
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 Fed-

eral, state/province and/or other applicable regula- tions.
Trailer lights
Connection of trailer lights to your vehicle ’s electrical
system requires modifications to the vehicle ’s light-
ing circuit to increase its capacity and accommo-
date wiring changes. To ensure the trailer lights are
connected properly, please consult your SUBARU
dealer. Check for proper operation of the turn sig-nals, the brake lights and parking lights each timeyou hitch up.
CAUTION
Direct splicing or other improper connection
of trailer lights may damage your vehicle ’s
electrical system and cause a malfunction ofyour vehicle ’s lighting system.
Tires
Make sure that all the tires on your vehicle are prop-
erly inflated to the pressure specified on the tire
placard located on the left center pillar of your ve-hicle.
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.
WARNING
Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not
designed to sustain the towing load. Use ofthe temporary spare tire when towing canresult in failure of the spare tire and/or less
stability of the vehicle.
Trailer towing tips
CAUTION
Never exceed 45 mph (72 km/h) when tow-
ing a trailer in hilly country on hot days. When towing a trailer, steering, stability,
stopping distance and braking performancewill be different from normal operation. For

large trucks or buses. If swaying occurs, firmly grip the steering wheel and slow down immediately but
gradually.When passing other vehicles, considerable dis-
tance is required because of the added weight and
length caused by attaching the trailer to your vehicle.
1) Left turn 2) Right turn
Backing up with a trailer is difficult and takes
practice. When backing up with a trailer, never
accelerate or steer rapidly. When turning back, gripthe 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 dealer.
Driving on grades
Before going down a steep hill, slow down and
shift into lower gear (if necessary, use 1st gear) in
order to utilize the engine braking effect and prevent
overheating of your vehicle ’s brakes. Do not make
sudden downshifts. When driving uphill in hot weather, the air condi-
tioner may turn off automatically to protect the
engine from overheating. When driving uphill in hot weather, pay attention to
the water temperature gauge pointer (for all
vehicles) and AT OIL TEMP warning light (for AT
vehicles) since the engine and transmission are rel-
atively prone to overheating under these conditions.
If the water temperature gauge pointer approaches
the OVERHEAT zone or the AT OIL TEMP warning
light illuminates, immediately switch off the air condi-
tioner and stop the vehicle at the nearest safe place.Refer to the “Engine overheat ” section in chapter 9,
and “Warning and indicator lights ” section in chap-
ter 3.
