aged. "
Either center pillar and rear wheel house or a
nearby area of the vehicle was involved in an acci-
dent in which the SRS side airbag and SRS curtain
airbag did not deploy. " The fabric or leather of either front seatback is
cut, frayed, or otherwise damaged. ! Precautions against vehicle modifica- tion
"To avoid accidental activation of the system
or rendering the system inoperative, which may
result in serious injury, no modifications
should be made to any components or wiring of
the SRS airbag system.
This includes following modifications: "Installation of custom steering wheels
" Attachment of additional trim materials to
the dashboard " Installation of custom seats
" Replacement of seat fabric or leather
" Installation of additional fabric or leather on the front seat "
Attachment of a hands-free microphone or
any other accessory to a front pillar, a center
pillar, a rear pillar, the windshield, a side win-
dow, an assist grip, or any other cabin sur-
face that would be near a deploying SRS cur-
tain airbag.
" Installation of additional electrical/electronic
equipment such as a mobile two-way radio on
or near the SRS airbag system components
and/or wiring is not advisable. This could inter-
fere with proper operation of the SRS airbag
system.
Do not perform any of the following modifica-
tions. Such modifications can interfere with
proper operation of the SRS airbag system. " Attachment of any equipment (bush bar,
winches, snow plow, skid plate, etc.) other than
genuine SUBARU accessory parts. " Modification of the suspension system or
front end structure. " Installation of a tire of different size and con-
struction from the tires specified on the vehicle

Instruments and controls
ing, you should have your Tire Pressure Moni-
toring System checked at a SUBARU dealer as
soon as possible.
If this light comes on while driving, never brake
suddenly and keep driving straight ahead while
gradually reducing speed. Then slowly pull off
the road to a safe place. Otherwise an accident
involving serious vehicle damage and serious
personal injury could occur.
If this light still comes on while driving after ad-
justing the tire pressure, a tire may have signif-
icant damage and a fast leak that causes the
tire to lose air rapidly. If you have a flat tire, re-
place it with a spare tire as soon as possible.
When a spare tire is mounted or a wheel rim is
replaced without the original pressure sensor/
transmitter being transferred, the Low tire pres-
sure warning light will flash. This indicates the
TPMS is unable to monitor all four road wheels.
Contact your SUBARU dealer as soon as possi-
ble for tire and sensor replacement and/or sys-
tem resetting. If the light flashes, promptly con-
tact a SUBARU dealer to have the system in-
spected.
The tire pressure monitoring system is NOT a
substitute for manually checking tire pressure.
The tire pressure should be checked periodical-
ly (at least monthly) using a tire gauge. After
any change to tire pressure(s), the tire pressure
monitoring system will not re-check tire infla-
tion pressures until the vehicle is first driven
more than 20 mph (32 km/h). Be sure to install
the specified size for the front and rear tires.
! ABS warning light
The ABS warning light comes on when the ignition
switch is turned to the “ON” position and goes out after
about two seconds.
This is an indication that the ABS system is working
properly.
If the warning light behaves as follows, the ABS
system may not work properly.
When the warning light is on, the ABS function
shuts down; however, the conventional brake
system continues to operate normally.

Starting and operating
Rear viscous limited slip differential
(LSD) (if equipped)
"
Never start the engine while a tire on one side
is jacked up, as the vehicle may move. " If one rear tire is spinning in mud, avoid con-
tinued spinning at high speed as this could ad-
versely affect the LSD. " If a different size rear tire is temporarily used
(as in an emergency), it will adversely affect the
LSD. Always replace it with a regular size tire as
soon as possible.
The LSD provides optimum distribution of power ac-
cording to the difference in revolutions between the
right and left rear wheels that may be caused by cer-
tain driving conditions, thereby improving driving sta-
bility on snow-covered, muddy or other slippery roads.
Power steering
Do not hold the steering wheel at the fully
locked position left or right for more than five
seconds. This may damage the power steering
pump.
The power steering system operates only when the
engine is running.
If you lose power steering assist because the engine
stops or the system fails to function, you can steer but
it will take much more effort.
NOTE
Right after the engine has been started and before
it has warmed up, you may hear a noise coming
from areas adjacent to the power steering pump
which is located at the right-front area of the en-
gine compartment. This noise is normal. It does
not indicate power steering system trouble.

Vehicle Dynamics Control system (if
equipped)
Always use the utmost care in driving – over-
confidence because you are driving with a Ve-
hicle Dynamics Control system equipped vehi-
cle could easily lead to a serious accident.
"Even if your vehicle is equipped with Vehicle
Dynamics Control, winter tires or snow chains
should be used when driving on snow-covered
or icy roads; in addition, vehicle speed should
be reduced considerably. Simply having a Vehi-
cle Dynamics Control system does not guaran-
tee that the vehicle will be able to avoid acci-
dents in any situation." Activation of the Vehicle Dynamics Control
system is an indication that the road being trav-
elled on has a slippery surface; since having
Vehicle Dynamics Control is no guarantee that
full vehicle control will be maintained at all
times and under all conditions, its activation should be seen as a sign that the speed of the
vehicle should be reduced considerably."
Whenever suspension components, steering
components, or an axle are removed from a ve-
hicle equipped with Vehicle Dynamics Control,
have an authorized SUBARU dealer perform an
inspection of that system. " The following precautions should be ob-
served in order to ensure that the Vehicle Dy-
namics Control system is operating properly: – All four wheels should be fitted with tires of
the same size, type, and brand. Furthermore,
the amount of wear should be the same for all four tires.
– Keep the tire pressure at the proper level as
shown on the vehicle placard attached to the
driver’s side door pillar.
In the event of wheelspin and/or skidding on a slippery
road surface and/or during cornering and/or an eva-
sive maneuver, the Vehicle Dynamics Control system
adjusts the engine’s output and the wheels’ respective
braking forces to help maintain traction and directional control. " Traction Control Function
The traction control function is designed to prevent

7-44
Starting and operating
spinning of the driving wheels on slippery road surfac-
es, thereby helping to maintain traction and directional
control. Activation of this function is shown by steady
illumination of the Vehicle Dynamics Control operation
indicator light. "
Skid Suppression Function
The skid suppression function is designed to help
maintain directional stability by suppressing the
wheels’ tendency to slide sideways during steering op-
erations. Activation of this function is shown by flash-
ing of the Vehicle Dynamics Control operation indica-
tor light.
NOTE " Slight twitching of the brake pedal may be felt
when the Vehicle Dynamics Control system oper-
ates; a small degree of vehicle or steering wheel
shaking may also be noticed in this situation.
These are normal characteristics of Vehicle Dy-
namics Control operation and are no cause for
alarm. " When driving off immediately after starting the
engine, a short-lived operation noise may be no-
ticed coming from the engine compartment. This
noise is generated as a result of a check being per-
formed on the Vehicle Dynamics Control system
and is normal. "
Depending on the timing of activation of the
brakes, certain situations may occur just after
driving off where the brake pedal seems to exhibit
a jolting motion. This too is a consequence of the
Vehicle Dynamics Control operational check and
is normal. " In the circumstances listed below, the vehicle
may be more unstable than it feels to the driver.
The Vehicle Dynamics Control System may there-
fore operate. Such operation does not indicate a
system fault. "on gravel-covered or rutted roads
" on unfinished roads
" when the vehicle is towing a trailer
" when the vehicle is fitted with snow tires or
winter tires
" Activation of the Vehicle Dynamics Control sys-
tem will cause operation of the steering wheel to
feel slightly different compared to that for normal
conditions." Even if the vehicle is equipped with a Vehicle
Dynamics Control system, it is important that win-
ter tires be used when driving on snow-covered or
icy roads. (All four wheels should be fitted with
tires of the same size and brand). Furthermore, if
snow chains are to be used, they should be fitted
on the front wheels. When a vehicle is fitted with

7-45

snow chains, however, the effectiveness of the Ve-
hicle Dynamics Control system is reduced and
this should be taken into account when driving the
vehicle in such a condition. "It is always important to reduce speed when ap-
proaching a corner, even if the vehicle is equipped
with Vehicle Dynamics Control. " All four wheels should be fitted with tires of the
same size, type, and brand; furthermore, the
amount of wear should be the same for all four
tires. If these precautions are not observed and
non-matching tires are used, it is quite possible
that the Vehicle Dynamics Control system will be
unable to operate correctly as intended." Always turn off the engine before replacing a
tire as failure to do so may render the Vehicle Dy-
namics Control system unable to operate correct-ly. !

Driving tips
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 acceler-
ation, and added engine braking force during deceler-
ation.
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 following tips in mind:
"
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 han-
dling, however, 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 ample distance from other vehicles. " When replacing a tire, make sure you use only the
same size, circumference, construction, brand, and
load range as the original tires listed on the tire plac-
ard. Using other sizes, circumferences or construction
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. " If you use a temporary spare tire to replace 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 yourvehicle. " Always check the cold tire pressure before starting
to drive. The recommended tire pressure is provided
on the tire placard, which is located under the door
latch on the driver’s side. " Tire chains should always be placed on the front
wheels only.

!Tire chains
Tire chains cannot be used on tires listed below
because of lack of clearance between the tires
and vehicle body. "2.5-liter non-turbo models (except OUT-
BACK): P205/55R16 tires " 2.5-liter turbo models (except OUTBACK):
215/45ZR17 tires " 2.5-liter non-turbo models (OUTBACK): P225/
60R16 tires" 2.5-liter turbo and 3.0-liter models (OUT-
BACK): P225/55R17 tires " 2.5-liter non-turbo and 3.0-liter models (OUT-
BACK): P225/60R16 winter (snow) tires " 2.5-liter non-turbo and 3.0-liter models (OUT-
BACK): P215/60R16 winter (snow) tires " 2.5-liter turbo and 3.0-liter models (OUT-
BACK): P215/55R17 winter (snow) tires
Driving on snowy grades or icy roads may require the
use of tire chains, in which case put the chains on the
front wheels only. Use only SAE class S type chains
that are of the correct size for your tires so as not to
damage the vehicle body or suspension. When driving with tire chains, drive at speeds below
19 mph (30 km/h). When a temporary spare tire is on
a front wheel, replace the temporary spare tire with the
rear tire on the same side of the vehicle, and then fit
chains on the front tires.
Always use the utmost care when driving with tire
chains – overconfidence because you are driving with
tire chains could easily lead to a serious accident. !
Rocking the vehicle
If you must rock the vehicle to free it from snow, 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 with the
transmission in 2nd than 1st (both for MT and AT).
Refer to the “Automatic transmission” section in chap-
ter 7 for information on holding the transmission in 2nd
position.

Trailer towing
Your vehicle is designed and intended to be used pri-
marily as a passenger-carrying vehicle. Towing a trail-
er puts additional loads on your vehicle’s engine, driv-
etrain, brakes, tires and suspension and has an ad-
verse effect 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.
"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

Temporary spare tire
"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 and may lead to an accident. " When a spare tire is mounted or a wheel rim
is replaced without the original pressure sen-
sor/transmitter being transferred, the low tire
pressure warning light will flash. This indicates
the tire pressure monitoring system (TPMS) is
unable to monitor all four road wheels. Contact
your SUBARU dealer as soon as possible for
tire and sensor replacement and/or system re-
setting.
Never use any temporary spare tire other than
the original. Using other sizes may result in se-
vere mechanical damage to the drive train of
your vehicle.
The temporary spare tire is smaller and lighter than a
conventional tire and is designed for emergency use
only. Remove the temporary spare tire and re-install
the conventional tire as soon as possible because the
spare tire is designed only for temporary use.
Check the inflation pressure of the temporary spare
tire periodically to keep the tire ready for use. The cor-
rect pressure is 60 psi (420 kPa, 4.2 kgf/cm 2
).
When using the temporary spare tire, note the follow-
ing: " Do not exceed 50 mph (80 km/h).
" Do not put a tire chain on the temporary spare tire.
Because of the smaller tire size, a tire chain will not fit
properly. " Do not use two or more temporary spare tires at the
same time. " Do not drive over obstacles. This tire has a smaller
diameter, so road clearance is reduced.
