aid kit and portable phone or citizens band radio. Drive carefully. Do not take unnecessary risks by
driving in dangerous areas or over rough terrain. Slow down and employ extra caution at all times.
When driving off-road, you will not have the benefit
of marked traffic lanes, banked curves, traffic signs and the like. Do not drive across steep slopes. Instead, drive
either straight up or straight down the slopes. A ve-
hicle can much more easily tip over sideways than it
can end over end. Avoid driving straight up or down
slopes that are too steep. Avoid sharp turning maneuvers, especially at
higher speeds. Do not grip the inside or spokes of the steering
wheel. A bad bump could jerk the wheel and injureyour hands. Instead drive with your fingers andthumbs on the outside of the rim. If driving through water, such as when crossing
shallow streams, first check the depth of the water
and the bottom of the stream bed for firmness and
ensure that the bed of the stream is flat. Drive slowly
and completely through the stream. The water
should be shallow enough that it does not reach the
vehicle’ s undercarriage. Water entering the engine
air intake or the exhaust pipe or water splashing
onto electrical parts may damage your vehicle and may cause it to stall. Never attempt to drive through
rushing water; regardless of its depth, it can wash
away the ground from under your tires, resulting in
possible loss of traction and even vehicle rollover.
Always check your brakes for effectiveness im-
mediately after driving in sand, mud or water. Do
this by driving slowly and stepping on the brake
pedal. Repeat that process several times to dry outthe brake discs and brake pads. Do not drive or park over or near flammable mate-
rials such as dry grass or fallen leaves, as they may
burn easily. The exhaust system is very hot while the
engine is running and right after the engine stops.
This could create a fire hazard. After driving through tall grass, mud, rock, sand,
rivers, etc., check that there is no grass, bush, pa-
per, rags, stones, sand, etc. adhering to or trapped
on the underbody. Clear off any such matter from
the underbody. If the vehicle is used with these ma-
terials trapped or adhering to the underbody, a
mechanical breakdown or fire could occur. Secure all cargo carried inside the vehicle and
make certain that it is not piled higher than the seat-
backs. During sudden stops or jolts, unsecured car-
go could be thrown around in the vehicle and cause
injury. Do not pile heavy loads on the roof. Thoseloads raise the vehicle ’s center of gravity and make

it more prone to tip over. If you must rock the vehicle to free it from sand or
mud, depress the accelerator pedal slightly and
move the selector lever back and forth between “D”
and “R” repeatedly. Do not race the engine. For the
best possible traction, avoid spinning the wheels
when trying to free the vehicle.
When the road surface is extremely slippery, you
can obtain better traction by starting the vehicle withthe transmission in 2nd than 1st (both for MT and
AT). Never equip your vehicle with tires larger than
those specified in this manual. Frequent driving of an AWD vehicle under hard-
driving conditions such as rough roads or off roads
will necessitate more frequent replacement of engine
oil, brake fluid and transmission oil than that specified
in the maintenance schedule described in the “War -
ranty and Maintenance Booklet ”.
Remember that damage done to your Subaru while
operating it off-road and not using common sense
precautions such as those listed above is not eligi-ble for warranty coverage. Winter driving

Operation during cold weather
Carry some emergency equipment, such as tire
chains, a window scraper, a bag of sand, flares, a small shovel, and jumper cables.
Check the battery and cables. Cold temperatures
reduce battery capacity. The battery must be in
good condition to provide enough power for cold
winter starts.
Use an engine oil of proper grade and viscosity for

cold weather. Heavy summer oil will cause harder
starting.
Keep the door locks from freezing by squirting themwith deicer or glycerin.
Forcing a frozen door open may damage or sepa-
rate the rubber weather strips around the door. If the
door is frozen, use hot water to melt the ice, and af-
terwards thoroughly wipe the water away. Use a windshield washer fluid that contains an anti-
freeze solution. Do not use engine antifreeze or oth-
er substitutes because they may damage the paint of the vehicle.
Before driving your vehicle
Before entering the vehicle, remove any snow or ice
from your shoes because that could make the ped-
als slippery and dangerous.
While warming up the vehicle before driving, check that the accelerator pedal, brake pedal, and all oth-
er controls operate smoothly. Clear away ice and snow that has accumulated un-
der the fenders to avoid making steering difficult.
During severe winter driving, stop when and where it is safe to do so and check under the fenders peri-
odically.
Parking in cold weather
Do not use the parking brake when parking for long
periods in cold weather since it could freeze in that
position. Instead, observe the following:
1. Place the shift lever in “1” or “R” for manual trans-
mission vehicles, and in “P” for automatic transmis-
sion vehicles.
2. Use tire stops under the tires to prevent the ve-
hicle from moving.
When the vehicle is parked in snow or when it
snows, raise the wiper blades off the glass to pre-vent damage to them.
When the vehicle has been left parked after use on
roads heavily covered with snow, or has been left
parked during a snowstorm, icing may develop onthe brake system, which could cause poor braking
action. Check for snow or ice buildup on the sus-
pension, disc brakes and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it, being care-ful not to damage the disc brakes and brake hoses
and ABS harness.

WARNING
Snow can trap dangerous exhaust gases under your vehicle. Keep snow clear of the
exhaust pipe and from around your vehicle ifyou park the vehicle in snow with the engine running.
Refueling in cold weather
To help prevent moisture from forming in the fuel
system and the risk of its freezing, use of an anti-
freeze additive in the fuel tank is recommended dur-
ing cold weather.
Use only additives that are specifically designed for
this purpose. When an antifreeze additive is used,
its effect lasts longer if the tank is refilled whenever
the fuel level reaches half empty. If your SUBARU is not going to be used for an ex-
tended period, it is best to have the fuel tank filled to
capacity. Driving on snowy and icy roads
To prevent skidding and slipping, avoid sudden braking, abrupt acceleration, high-speed driving,
and sharp turning when driving on snowy or icy roads.
Always maintain ample distance between your ve-
hicle and the vehicle ahead of you to avoid the needfor sudden braking.
To supplement the foot brake, use the engine brake
effectively to control the vehicle speed. (Shift into a
lower gear when necessary.)
Avoid shifting down abruptly. Such behavior cancause the wheels to lock, possibly leading to loss of
vehicle control.
An anti-lock brake system (ABS) e
nhances your
vehicle’ s braking performance on snowy and icy
roads. Refer to the “ABS (Anti-Lock Brake System) ”
section in chapter 7 for information on braking on
slippery surfaces. NOTE The optional 17-inch tires for the WRX are sum- mer tires. Compared with winter and all-season tires, summer tires give significantly less grip on
snowy and icy road surfaces. Avoid driving onsnowy and icy road surface with summer tires.

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

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.

CAUTION
Do not modify the vehicle exhaust system,
brake system, or other systems when instal- ling a hitch or other trailer towing equipment. Do not use axle-mounted hitches as they
can cause damage to the axle housing, wheelbearings, wheels or tires.
WAGON including OUTBACK SPORT
The use of a genuine SUBARU trailer hitch is recom-
mended. A genuine SUBARU hitch is available from
your SUBARU dealer.
If use of a non-genuine hitch is unavoidable, be sure
the hitch is suited to your vehicle and trailer. Consult
with a professional hitch supplier to assist you in
choosing an appropriate hitch for your vehicle. Be
sure to follow all of the hitch manufacturer ’s instruc-
tions for installation and use.
Never use a hitch that mounts only to the rear bum-
per. The bumper is not designed to handle that typeof load.
For all types of hitches, regularly check that the
hitch mounting bolts and nuts are tight.
SEDAN
SUBARU does not offer accessory trailer hitches. Consult with a professional hitch supplier to assist
you in choosing an appropriate hitch for your ve-
hicle. Be sure to follow all of the hitch manufacturer
’s
instructions for installation and use.
Never use a hitch that mounts only to the rear bum-
per. The bumper is not designed to handle that type of load. Regularly check that the hitch mounting bolts and
nuts are tight.
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 required to be equipped with its own brake sys-
tem. Electric brakes or surge brakes are recom-
mended, and must be installed properly. Check thatyour 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 trail-er’ s brake system.

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-
