end. y Modification of the suspension system or
front end structure. y Installation of a tire of different size and con-
struction from the tires specified on the tire
placard attached to the door jamb.
Child restraint systems
Infants and small children should always be placed in
an infant or child restraint system in the rear seat while
riding in the vehicle. You should use an infant or child
restraint system that meets Federal Motor Vehicle
Safety Standards or Canada Motor Vehicle Safety
Standards, is compatible with your vehicle and is ap-
propriate for the child’s age and size. All child restraint
systems are designed to be secured in vehicle seats
by lap belts or the lap belt portion of a lap/shoulder belt
(except those covered under the section in this manu-al, entitled “Installation of child restraint systems by
use of lower and tether anchorages (LATCH)”).

y
Never start the engine while a tire on one side
is jacked up, as the vehicle may move. y If one rear tire is spinning in mud, avoid con-
tinued spinning at high speed as this could ad-
versely affect the LSD. y 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.

yWhenever suspension components, steering
components, or an axle are removed from a ve-
hicle equipped with VDC, have an authorized
SUBARU dealer perform an inspection of that
system.y The following precautions should be ob-
served in order to ensure that the VDC 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 allfour tires.
– Keep the tire pressure at the proper level as
shown on the placard attached to the vehi-
cle’s door pillar.
– Use only the special temporary spare tire to
replace a flat tire. With a temporary spare tire,
the effectiveness of the VDC system is re-
duced and this should be taken into account
when driving with vehicle.
In the event of wheelspin and/or skidding on a slippery
road surface and/or during cornering and/or an eva-
sive maneuver, the VDC system adjusts the engine’s
output and the wheels’ respective braking forces to
help maintain traction and directional control. y
Traction Control Function
The traction control function is designed to prevent
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 VDC operation indicator light. y 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 VDC operation indicator light.
NOTE y Slight twitching of the brake pedal may be felt
when the VDC-system operates; a small degree of
vehicle or steering wheel shaking may also be no-
ticed in this situation. These are normal character-
istics of VDC operation and are no cause for
alarm. y 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 VDC system and is normal.y 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
VDC operational check and is normal. y
In the circumstances listed below, the vehicle
may be more unstable than it feels to the driver.

fore operate. Such operation does not indicate a
system fault.
yon gravel-covered or rutted roads
y on unfinished roads
y when the vehicle is towing a trailer
y when the vehicle is fitted with snow tires or
winter tires
y Activation of the VDC system will cause opera-
tion of the steering wheel to feel slightly different
compared to that for normal conditions. y Even if the vehicle is equipped with a VDC sys-
tem, it is important that winter 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). y It is always important to reduce speed when ap-
proaching a corner, even if the vehicle is equipped with VDC. y 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 VDC system will be unable to operate cor-
rectly as intended. y
Always turn off the engine before replacing a
tire as failure to do so may render the VDC system
unable to operate correctly. „ VDC system monitor

Driving tips
– CONTINUED –
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: 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 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. y 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. y 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 your
vehicle. y 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. y Tire chains should always be placed on the front
wheels only.

Snow tires
T All models except OUTBACK
yWhen replacing original tires with winter
(snow) tires, make sure you use only the same
size, construction and load range as the origi-
nal tires listed on the tire placard. Using other
sizes and construction may affect speedome-
ter/odometer calibration and clearance be-
tween the body and tires. It also may be danger-
ous and lead to loss of vehicle control. y You must install four winter tires that are of
the same size, circumferences, construction,
brand, and load range. Mixing other sizes, cir-
cumferences or constructions may result in se-
vere mechanical damage to the drive train of
your vehicle and may affect ride, handling,
braking and speedometer/odometer calibra-
tion. It also may be dangerous and lead to loss
of vehicle control. y Do not use a combination of radial, belted
bias or bias tires since it may cause dangerous
handling characteristics and lead to an acci-
dent. Your vehicle is equipped with “all season tires” which
are designed to provide an adequate measure of trac-
tion, handling and braking performance in year-round
driving. In winter, it may be possible to enhance per-
formance through use of tires designed specifically for
winter driving conditions.
If you choose to install winter tires on your vehicle, be
sure to use the correct tire size and type. You must in-
stall four winter tires that are of the same size, con-
struction, brand and load range and you should never
mix radial, belted bias or bias tires since this may re-
sult in dangerous handling characteristics. When you
choose a tire, make sure that there is enough clear-
ance between the tire and vehicle body.
Remember to drive with care at all times regardless of
the type of tires on your vehicle. T

Driving tips
models
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.

cal system and cause a malfunction of your ve-
hicle’s lighting system.
Connection of trailer lights to your vehicle’s electrical
system requires modifications to the vehicle’s lighting
circuit to increase 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
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.
Make sure that all the tires on your vehicle are properly
inflated.
The recommended cold tire pressure under trailer tow-
ing 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 recom-
mended pressure when the tires are cold. Normal
pressure should be maintained in the front tires.
Trailer tire condition, size, load rating and proper infla-
tion 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 tipsyNever exceed 45 mph (72 km/h) when towing
a trailer in hilly country on hot days. y When towing a trailer, steering, stability,
stopping distance and braking performance
will be different from normal operation. For
safety’s sake, you should employ extra caution
when towing a trailer and you should never
