Driving tips for AWD vehicles
All-Wheel Drive distributes the engine
power to all four wheels. AWD vehicles provide better traction when driving on
slippery, wet or snow-covered roads and
when moving out of mud, dirt and sand. By
shifting power between the front and rear
wheels, SUBARU AWD can also provide
added traction during acceleration, and
added engine braking force during decel-
eration.
Therefore, your SUBARU AWD vehicle
may handle differently than an ordinary
two wheel drive vehicle and it contains
some features unique to AWD. For safety
purposes as well as to avoid damaging
the AWD system, you should keep the fol-
lowing tips in mind:
y An AWD vehicle is better able to climb
steeper roads under snowy or slippery
conditions than a two wheel drive vehicle.
There is little difference in handling, how-
ever, during extremely sharp turns or sud-
den braking. Therefore, when driving
down a slope or turning corners, be sure
to reduce your speed and maintain an am-
ple distance from other vehicles.
y When replacing a ti re, make sure you
use only the same si ze, circumference,
construction, brand, and load range as the
original tires listed on the tire placard. Us-
ing other sizes, circumferences or con-
struction may result in severe mechanical
damage to the drive train of your vehicle
and may affect ride, handling, braking, speedometer/odometer calibration, and
clearance between the body and tires. It
also may be dangerous and lead to loss of
vehicle control.
y If you use a temporary spare tire to re-
place a flat tire, be sure to use the original
temporary spare tire stored in the vehicle.
Using other sizes may result in severe
mechanical damage to the drive train of
your vehicle.
y Always check the cold tire pressure be-
fore starting to drive. The recommended
tire pressure is provided on the tire plac-
ard, which is located under the door latch
on the driver’s side.
y Tire chains should always be placed on
the front wheels only.
y There are some precautions that you
must observe when towing your vehicle.
For detail information, see “Towing” sec-
tion in chapter 9.y Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden braking
or under other similar conditions.
y Always use the utmost care in
driving – overconfidence because
you are driving an All-Wheel Drive
vehicle could easily lead to a seri-
ous accident.

Off road driving
T All AWD models except OUTBACK
Your AWD vehicle is neither a convention-
al off-road vehicle nor an all terrain vehi-
cle. It is a passenger car designed prima-
rily for on-road use. The AWD feature
gives it some limited off-road capabilities
in situations in which driving surfaces a
relatively level, obstruction-free and other-
wise similar to on-road driving conditions.
Operating it under other than those condi-
tions could subject the vehicle to exces-
sive stress which might result in damage
not eligible for repair under warranty. If
you do take your SUBARU off road, you
should review the common sense precau- tions in the next section (applicable to the
OUTBACK) for general guidance. But
please keep in mind that your vehicle’s
off-road capabilities are more limited than
those of the OUTBACK.
Never attempt to drive through pools and
puddles, or roads flooded with water. Wa-
ter entering the engine air intake or the ex-
haust pipe or water splashing onto electri-
cal parts may damage your vehicle and
may cause it to stall.
T OUTBACK
Because of the AWD feature and higher
ground clearance, your SUBARU can be
driven on ordinary roads or off-road. But
please keep in mind that an AWD
SUBARU is a passenger car and is nei-
ther a conventional off-road vehicle nor an
all-terrain vehicle. If you do take your
SUBARU off-road, ce rtain common sense
precautions such as the following should
be taken:
y Make certain that you and all of your
passengers are wearing seatbelts.
y Carry some emergency equipment,
such as a towing rope or chain, a shovel,
wheel blocks, first aid kit and cell phone or
citizens band radio.
y Drive carefully. Do not take unneces-
sary risks by driving in dangerous areas or
over rough terrain. y 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.
y Do not drive across steep slopes. In-
stead, drive either st raight up or straight
down the slopes. A vehicle can much
more easily tip over sideways than it can
end over end. Avoid driving straight up or
down slopes that are too steep.
y Avoid sharp turning maneuvers, espe-
cially at higher speeds.
y Do not grip the inside or spokes of the
steering wheel. A bad bump could jerk the
wheel and injure your hands. Instead drive
with your fingers and thumbs on the out-
side of the rim.
y 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 undercar-
riage. Water entering the engine air intake
or the exhaust pipe or water splashing
onto electrical parts may damage your ve-
hicle and may cause it to stall. Never at-
tempt to drive through rushing water; re-
gardless of its depth, it can wash away they Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden braking
or under other similar conditions.
y Always use the utmost care in
driving – overconfidence because
you are driving an All-Wheel Drive
vehicle could easily lead to a seri-
ous accident.

NOTE Before each use of the roof crossbar,
make sure the four T-30 crossbar
clamp screws have been checked, and
retightened if necessary to 35 lbf·in (4.0
N·m, 0.41 kgf·m), as outlined in Step #5
above.
Trailer hitch (if equipped)
The trailer hitch is designed to tow a Class
1 rated load. The maximum gross trailer
weight and maximum gross tongue weight
are indicated in the following table.
When you tow a trailer, follow the instruc-
tions in the next section “Trailer towing”.y Never exceed the maximum
weight specified for the trailer
hitch. Exceeding the maximum
weight could cause an accident
resulting in serious personal inju-
ries. Permissible trailer weight
changes depending on the situa-
tion. Refer to th e next section
“Trailer towing” for possible rec-
ommendations and limitations.
y 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 maximum
gross weight. Towing trailers
without safety chains could create
a traffic safety haza rd if the trailer
separates from the hitch due to
coupling damage or hitch ball
damage. y Be sure to check the hitch pin and
safety pin for positive locking
placement before towing a trailer.
If the ball moun t comes off the
hitch receiver, the trailer could get
loose and create a traffic safety
hazard.
y Use only the ball mount supplied
with this hitch. Use the hitch only
as a weight carrying hitch. Do not
use with any type of weight dis-
tributing hitch.

four-pin wire connector to the towing trail-
er’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 har-
ness before launching or retrieving a
watercraft. „ When you do not tow a trailer y Remove the ball mount from the hitch
receiver tube and insert the receiver cover
onto the hitch receiver tube.
y Place the dust cap over the four-pin
connector of the hitch wire harness to pro-
tect against possible damage.
y Occasionally lubricate terminals of the
four-pin connector using the 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 safe-
ty and satisfaction depend upon proper
use of correct equipment and cautious op-
eration of your vehicle. Seek the advice of
your SUBARU dealer to assist you in pur-
chasing a hitch and other necessary tow-
ing equipment appropriate for your vehi-
cle. In addition, be sure to follow the in-
structions on correct installation and use
provided by the trailer and other towing
equipment manufacturers.
SUBARU assumes no responsibility for in-
juries or vehicle damage that result from
trailer towing equipment, or from any er-
rors or omissions in the instructions ac-
companying such equipment or for your
failure to follow the proper instructions.
„ Warranties and maintenance SUBARU warranties do not apply to vehi-
cle damage or malfunction caused by trail-
er towing. If you use your vehicle to tow a
trailer, more frequent maintenance will beDo not connect safety chains to part

If the trailer is loaded with more
weight in the back of trailer’s axle
than in the front, th e load is taken off
the rear axle of the towing vehicle.
This may cause the rear wheels to
skid, especially during braking or
when vehicle speed is reduced dur-
ing cornering, resulting in over-
steer, spin out and/or jackknifing. 800214

8-24 Driving tips
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 cou-
pler at the height at which it would be dur-
ing actual towing, using a jack as shown. F: Front
The tongue load can be adjusted by prop-
er 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 approx imately 40 percent in
the rear. Also, distribute the load as even-
ly 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 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 ve-
hicle and cause corrosion around
the drilled hole.
y Do not modify th e 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 bearings,
wheels or tires.

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 ve-
hicle and trailer. Consult with a profes-
sional hitch supplier to assist you in
choosing an appropriate hitch for your ve-
hicle. Be sure to follow all of the hitch man-
ufacturer’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 are
tight.
T All vehicles except OUTBACK wag-
on
SUBARU does not offer accessory trailer
hitches. Consult with a professional hitch
supplier to assist you in choosing an ap-
propriate hitch for your vehicle. Be sure to
follow all of the hitch manufacturer’s in-
structions 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 T 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 ow n brake system. Elec-
tric brakes or surge brakes are recom-
mended, 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 pro- fessional trailer supplier for more informa-
tion about the trailer’s brake system.
T Trailer safety chains
In case the trailer hitch connector or hitch
ball should break or become disconnect-
ed, the trailer could get loose and create a
traffic safety hazard.
For safety, always connect the towing ve-
hicle and trailer with trailer safety chains.
Pass the chains crossing each other un-
der 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 ac-
count; however, be ca reful 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.y Adequate size trailer brakes are
required when the trailer and its
cargo exceed 1,000 lbs (453 kg)
total weight.
y Do not directly connect your trail-
er’s hydraulic brake system to the
hydraulic brake system in your
vehicle. Direct connection would
cause the vehicle’s brake perfor-
mance to deteriorate and could
lead to an accident. Always use safety chains between
your vehicle and the trailer. Towing
trailer without safe ty chains could
create a traffic safety hazard if the
trailer separates fr om the hitch due
to coupling damage or hitch ball
damage.

8-26 Driving tips
T Side mirrors
After hitching a trailer to your vehicle,
check that the standard side mirrors pro-
vide 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 con-
form with Federal, state/province and/or
other applicable regulations.
T Trailer lights Connection of trailer lights to your vehi-
cle’s electrical system requires modifica-
tions to the vehicle’s lighting circuit to in-
crease 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
Make sure that all the tires on your vehicle
are properly inflated.
The recommended cold tire pressure un-
der trailer towing 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 recommended pressure when the tires
are cold. Normal pressure should be maintained in the front tires.
Trailer tire condition, size, load rating and
proper inflation pressure should be in ac-
cordance with the trailer manufacturer’s
specifications.
In the event your v ehicle 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
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. 800018
Never tow a trailer when the tempo-
rary spare tire is used. The tempo-
rary 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. y Never exceed 45 mph (72 km/h)
when towing a trailer in hilly coun-
try on hot days.
y When towing a trailer, steering,
stability, stopping distance and
braking performance will be dif-
ferent from normal operation. For
safety’s sake, you should employ
extra caution when towing a trail-
er and you should never speed.
You should also keep the follow-
ing tips in mind:
