could make the pedals slippery and
driving dangerous.
While warming up the vehicle before
driving, check that the accelerator pedal,
brake pedal, and all other controls operate
smoothly.
Clear away ice and snow that has
accumulated under 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
periodically. !Parking in cold weather
WARNING
Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle if you park
the vehicle in snow with the enginerunning.
Do not use the parking brake when
parking for long periods in cold weather
since it could freeze in that position.
Instead, you should observe the followingtips.
1. Place the shift lever in “1 ” or “R ”for MT
models, or the select lever in “P ” for AT
models and CVT models. 2. Use tire stops under the tires to
prevent the vehicle from moving.
When the vehicle is parked in snow or
when it snows, raise the wiper blades off
the glass to prevent 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 on the
brake system, which could cause poor
braking action. Check for snow or ice
buildup on the suspension, disc brakes
and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it,
being careful not to damage the disc
brakes and brake hoses and ABS har-ness. !
Refueling in cold weather
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during 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 extended period, it is best to have
the fuel tank filled to capacity. &
Driving on snowy and icy roads
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of
vehicle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine ’s intake system and may
hinder the air flow, which could
result in engine shutdown or evenbreakdown.
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 vehicle and the vehicle ahead of you
to avoid the need for 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 beha-
vior can cause the wheels to lock, possibly Driving tips

leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle ’s braking perfor-
mance on snowy and icy roads. For
information about braking on slippery
surfaces, refer to “ABS (Anti-lock Brake
System) ”F 7-25 and “Vehicle Dynamics
Control system ”F 7-28.
! Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blades are not frozen to the
windshield or rear window.
If the wiper blades are frozen to the
windshield or rear window, perform the
following procedure. . To thaw the windshield wiper blades,
use the defroster with the airflow selection in “
”and the temperature set for
maximum warmth until the wiper blades
are completely thawed. Refer to “Climate
control ”F 4-1.
. If your vehicle is equipped with a wiper
deicer, use it. It is helpful to thaw the
windshield wiper blades. Refer to “Defog-
ger and deicer ”F 3-34.
. To thaw the rear wiper blade, use the
rear window defogger. Refer to “Defogger
and deicer ”F 3-34.
When driving in snow, if frozen snow starts
to stick on the surface of the windshield despite wiper operation, use the defroster
with the airflow selection in
“
”and the
temperature set for maximum warmth.
After the windshield gets warmed enough
to melt the frozen snow on it, wash it away
using the windshield washer. Refer to“ Windshield washer ”F 3-33
Snow stuck on the wiper arm prevents the
wiper from working effectively. If snow is
stuck on the wiper arm, pull off the road to
a safe place, then remove it. If you stop
the vehicle at road side, use the hazard
warning flasher to alert other drivers.
Refer to “Hazard warning flasher ”F 3-5.
We recommend use of non-freezing type
wiper blades (winter blades) during the
seasons you could have snow and freez-
ing temperatures. Blades of this type give
superior wiping performance in snowy
conditions. Be sure to use blades that
are suitable for your vehicle.
CAUTION
During high-speed driving, non-
freezing type wiper blades may not
perform as well as standard wiper
blades. If this happens, reduce the
vehicle speed. NOTE
When the season requiring non-freez-
ing type wiper blades is over, replace
them with standard wiper blades. &
Corrosion protection
Refer to “Corrosion protection ”F 10-4.
& Snow tires
WARNING
. When replacing original tires with
winter (snow) tires, make sure
you use only the same size,
construction and load range as
the original tires listed on the tire
placard. Using other sizes and
construction may affect speed-
ometer/odometer calibration and
clearance between the body and
tires. It also may be dangerous
and lead to loss of vehicle con-trol.
. You must install four winter tires
that are of the same size, circum-
ferences, construction, brand,
andloadrange.Mixingother
sizes, circumferences or con-
structions may result in severe
mechanical damage to the drive

weight could cause an accident
resulting in serious personal in-
juries. Permissible trailer weight
changes depending on the situa-
tion. For possible recommenda-
tions and limitations, refer to“ Trailer towing ”F 8-19.
. 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 ’s max-
imum gross weight. Towing trai-
lers without safety chains could
create a traffic safety hazard if
the trailer separates from the
hitch due to coupling damage or
hitch ball damage.
. Be sure to check the hitch pin
and safety pin for positive lock-
ing placement before towing a
trailer. If the ball mount comes off
the hitch receiver, the trailer

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 awatercraft. &
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.

Trailer towing
Your vehicle is designed and intended to
be used primarily as a passenger-carrying
vehicle. Towing a trailer puts additional
loads on your vehicle’s engine, drivetrain,
brakes, tires and suspension and has an
adverse effect on fuel economy.
If you do decide to tow a trailer, your safety
and satisfaction depend upon proper use
of correct equipment and cautious opera-
tion of your vehicle. Seek the 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 installation 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 equipment, or from any
errors or omissions in the instructions
accompanying such equipment or for your
failure 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 maintenance
will be required due to the additional load. (Refer to
“Maintenance 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 (en-
gine, 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 explained in the following.
Exceeding the maximum load limits
could cause personal injury and/or
vehicle 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 accepta- ble.

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.
GVWR is shown on the certification label
located on the driver ’s door of your
vehicle.

NOTE
For vehicles with trailer brakes, the
trailer tongue load exceeds 200 lbs (90
kg) when calculated at 8% of the
maximum total trailer weight.
Even in this case, the maximum value
is 200 lbs (90 kg).
1) Jack
2) Bathroom scale
The tongue load can be weighed with a
bathroom scale as shown in the following
illustration. 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 asshown.
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; 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. &
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. !Outback
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. ! Legacy
SUBARU does not offer accessory trailer
hitches. 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
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. Regularly check that the hitch mounting
bolts and nuts are tight.
& Connecting a trailer
! Trailer brakes
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 connection
would cause the vehicle ’s brake
performance to deteriorate and
could lead to an accident.
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 system.
Electric 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. YourSUBARU ’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 trailer
’s brake
system. ! Trailer safety chains
WARNING
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 balldamage.
In case the trailer hitch connector or hitch
ball should break or become discon-
nected, 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 prevent
the trailer from dropping onto the ground
in case the trailer tongue should discon-
nect from the hitch ball. Allow sufficient
slack in the chains taking tight-turn situa-
tions into account; however, be careful not
to let them drag on the ground.
For more information about the safety
chain connection, refer to the instructions
for your hitch and trailer. Driving tips

!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 stan-
dard side mirrors, use towing mirrors that
conform with Federal, state/province and/
or other applicable regulations. ! Trailer lights
CAUTION
Direct splicing or other improper
connection of trailer lights may
damage your vehicle ’s electrical
system and cause a malfunction of
your vehicle ’s lighting system. 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 turn signals and the brake
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. Refer to “Tires ”F 12-
5 and in “GAS STATION REFERENCE ”at
the end of this manual.
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.
& Trailer towing tips
CAUTION
. Never exceed 45 mph (72 km/h)
when towing a trailer in hilly
country on hot days.
. When towing a trailer, steering,
stability, stopping distance and
braking performance will be dif-
ferent from normal operation. Forsafety ’s sake, you should employ
extra caution when towing a
trailer and you should never
speed. You should also keep the
following tips in mind:
! Before starting out on a trip
. Check that the vehicle and vehicle-to-
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 ’s brake
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
properly.– all cargo in the trailer is secured
safety in position.– the side mirrors provide a good
rearward field of view without a sig-
nificant blind spot.
. Sufficient time should be taken to learn
the “feel ”of the vehicle/trailer combination
before starting out on a trip. In an area free
of traffic, practice turning, stopping and
backing up. !
Driving with a trailer
. You should allow for considerably more
stopping distance when towing a trailer.
Avoid sudden braking because it may
result in skidding or jackknifing and loss ofcontrol. . Avoid abrupt starts and sudden accel-
erations. If your vehicle has a manual
transmission, always start out in first gear
and release the clutch at moderate enginerevolution. . Avoid uneven steering, sharp turns and
rapid lane changes.. Slow down before turning. Make a
longer than normal turning radius because
the trailer wheels will be closer than the
vehicle wheels to the inside of the turn. In
a tight turn, the trailer could hit yourvehicle. . Crosswinds will adversely affect the
handling of your vehicle and trailer, caus-
ing sway. Crosswinds can be due to
weather conditions or the passing of large
trucks or buses. If swaying occurs, firmly
grip the steering wheel and slow down
immediately but gradually. . When passing other vehicles, consid-
erable distance 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, grip the 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 neces-
sary, use 1st gear) in order to utilize the Driving tips
