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 compo-
nents, steering components, or
an axle are removed from a
vehicle equipped with the Vehicle
Dynamics Control system, have
an inspection of that system
performedbyanauthorized
SUBARU dealer.
. The following precautions should
be observed in order to ensure
that the Vehicle Dynamics Con-
trol system is operating properly: – All four wheels should be
fitted with tires of the same
size, type, and brand. Further-
more, 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.
– Use only the specified tem-
porary spare tire to replace a
flat tire. With a temporary spare tire, the effectiveness of
the Vehicle Dynamics Control
system is reduced and this
should be taken into account
when driving the vehicle in
such a condition.
In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive 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 spinning of the driving wheels on
slippery road surfaces, thereby helping to
maintain traction and directional control.
Activation of this function is shown by
steady illumination of the Vehicle Dy-
namics 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 operations. Acti-
vation of this function is shown by flashing
of the Vehicle Dynamics Control operation
indicator light. NOTE .
Slight twitching of the brake pedal
may be felt when the Vehicle Dynamics
Control system operates; a small de-
gree of vehicle or steering wheel shak-
ing may also be noticed in this situa-
tion. These are normal characteristics
of Vehicle Dynamics Control operation
and are no cause for alarm.. When driving off immediately after
starting the engine, a short-lived opera-
tion noise may be noticed coming from
the engine compartment. This noise is
generated as a result of a check being
performed on the Vehicle Dynamics
Control system and is normal.. Depending on the timing of activa-
tion of the brakes, the brake pedal may
seem to jolt when you drive off after
starting the engine. This is a conse-
quence of the Vehicle Dynamics Con-
trol operational check and is normal.. In the circumstances listed in the
following, the vehicle may be more
unstable than it feels to the driver.
The Vehicle Dynamics Control System
may therefore operate. Such operation
does not indicate a system fault.

7-28Starting and operating
! Vehicle Dynamics Control warning light
The warning light illuminates when the
ignition switch is turned to the “ON ”
position and turns off several seconds
after engine startup. This lighting pattern
indicates that the Vehicle Dynamics Con-
trol system is operating normally.
The following situations could indicate a
malfunction of the Vehicle Dynamics
Control system; if any should occur, have
an authorized SUBARU dealer carry out
an inspection of the system at the first
available opportunity. . The warning light does not turn on
when the ignition switch is turned to the
ON position. . The warning light turns on while the
vehicle is being driven.. When a malfunction has occurred in
the Vehicle Dynamics Control electrical
system, only the warning light will turn on.
In such an event, the ABS will still be
operating normally. . The warning light will also turn on when
a problem occurs with the ABS or Vehicle
Dynamics Control electronic control sys-tems.
Because the Vehicle Dynamics Control
system controls each brake through the ABS, whenever the ABS stops operating
due to a malfunction in that electrical
system, the Vehicle Dynamics Control will
also become unable to control all four
brakes. Thus Vehicle Dynamics Control
system operation halts and the warning
light turns on. Although both the Vehicle
Dynamics Control system and the ABS
will be inoperable in this situation, it will
still be possible to stop the vehicle using
normal braking. The Vehicle Dynamics
Control system and the ABS do not
adversely affect operation of the vehicle
in any way when they are inoperable;
however should such a situation occur,
drive with care and have an authorized
SUBARU dealer carry out an inspection of
those systems at the first available oppor-
tunity. NOTE
When the warning light turns on and off
in the following way, it indicates that
the Vehicle Dynamics Control system
is operating normally. .
Although turning on after the engine
has been started, the warning light
quickly turns off and stays off.. The warning light turns on when the
vehicle is being driven; it then turns off
and stays off. !
Vehicle Dynamics Control OFF in-
dicator light
This light illuminates to indicate that the
Vehicle Dynamics Control system is in
non-operation mode. This does not con-
stitute failure of the Vehicle Dynamics
Control system. NOTE . The indicator light may remain on
for a while after the engine has been
started, especially in cold weather. This
occurs because the engine has not yet
warmed up and is completely normal.
The light will turn off when the engine
has reached a suitable operating tem-perature.. When an engine problem occurs
and the CHECK ENGINE warning light/
malfunction indicator lamp turns on,
the indicator light will also illuminate.
The following two situations could indicate
malfunction of the Vehicle Dynamics
Control system; if either should occur,
have an authorized SUBARU dealer carry
out an inspection of that system at the first
available opportunity. . The indicator light does not turn on
when the ignition switch is turned to the
ON position. . The indicator light fails to turn off after
the engine is started, even when several

!To decrease the speed (by brake pedal)
1. Depress the brake pedal to release
cruise control temporarily.
2. When the speed decreases to the
desired speed, press the “SET/COAST ”
button once. Now the desired speed is set
and the vehicle will keep running at that
speed without depressing the acceleratorpedal. & Cruise control indicator light
The cruise control indicator light illumi-
nates when the ignition switch is turned to
the “ON ”position and turns off after
approximately 3 seconds.
The light illuminates when the “CRUISE ”
main switch is pressed. NOTE .
If you press the “CRUISE ”main
switch button while turning the ignition switch “ON ”, the cruise control func-
tion is deactivated and the cruise
control indicator light flashes. To re-
activate the cruise control function,
turn the ignition switch back to the“ Acc ”or “LOCK ”position, and then
turn it again to the “ON ”position.
. If this indicator light and the CHECK
ENGINE warning light/malfunction in-
dicator lamp flash simultaneously dur-
ing driving, have the vehicle checked
by your nearest SUBARU dealer. &
Cruise control set indicator light
The cruise control set indicator light
illuminates when the ignition switch is
turned to the “ON ”position and turns off
after approximately 3 seconds.

exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open.
. Keep the rear gate closed while
driving to prevent exhaust gas
from entering the vehicle.
NOTE
Due to the expansion and contraction
of the metals used in the manufacture
of the exhaust system, you may hear a
crackling sound coming from the ex-
haust system for a short time after the
engine has been shut off. This sound isnormal. Catalytic converter
Turbo models
Non-turbo models
The catalytic converter is installed in the
exhaust system. It serves as a catalyst to reduce HC, CO and NOx in exhaust
gases, thus providing cleaner exhaust.
To avoid damage to the catalytic conver- ter: .
Use only unleaded fuel. Even a small
amount of leaded fuel will damage the
catalytic converter. . Never start the engine by pushing or
pulling the vehicle.. Avoid racing the engine.
. Never turn off the ignition switch while
the vehicle is moving.. Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), have
your vehicle checked and repaired by an
authorized SUBARU dealer. . Do not apply undercoating or rust
prevention treatment to the heat shield of
catalytic converter and the exhaust sys-tem. . Do not drive with an extremely low fuel
level.
WARNING
. Avoid fire hazards. Do not drive
or park the vehicle anywhere
near flammable materials (e.g.,
grass, paper, rags or leaves),

Driving tips for AWD models
All-Wheel Drive distributes the engine
power to all four wheels. AWD models
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 duringdeceleration.
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 model is better able to climb
steeper roads under snowy or slippery
conditions than a two wheel drive vehicle.
There is little difference in handling,
however, during extremely sharp turns or
sudden 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, construction,
brand, and load range as the original tires
listed on the tire placard. Using other
sizes, circumference or construction may
result in severe mechanical damage to the
drive train of your vehicle and may affect
ride, handling, braking, speedometer/od-
ometer calibration, and clearance be-
tween the body and tires. It also may be
dangerous and lead to loss of vehiclecontrol. . 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. . Always check the cold tire pressure
before starting to drive. The recom-
mended tire pressure is provided on the
tire placard, which is located under the
door latch on the driver ’s side. .
There are some precautions that you
must observe when towing your vehicle.
For detail information, refer to “Towing ”
F 9-12.
WARNING
. 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 brak-
ing or under other similar condi-tions.
. Always use the utmost care in
driving –overconfidence be-
cause you are driving an All-
Wheel Drive model could easily
lead to a serious accident. Driving tips

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
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 effec-
tiveness immediately 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 out the
brake discs and brake pads. . Do not drive or park over or near
flammable materials 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 engine
stops. This could create a fire hazard. . After driving through tall grass, mud,
rocks, sand, rivers, etc., check that there
is no grass, bush, paper, 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 materials 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 seatbacks. During
sudden stops or jolts, unsecured cargo
could be thrown around in the vehicle and
cause injury. Do not pile heavy loads on
the roof. Those loads 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 select 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. . Never equip your vehicle with tires
larger than those specified in this manual.. Wash the vehicle ’s underbody after off-
road driving. Suspension components are
particularly prone to dirt buildup, so they
need to be washed thoroughly. . Frequent driving of an AWD model 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
“Warranty and Mainte-
nance 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 eligible
for warranty coverage. Driving tips

8-8Driving tips
Winter driving
&Operation during cold weather
Carry some emergency equipment, such
as 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 winterstarts.
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 them with deicer or glycerin. Forcing a frozen door open may damage
or separate the rubber weather strips
around the door. If the door is frozen,
use hot water to melt the ice, and after-
wards thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.
SUBARU Windshield Washer Fluid con-
tains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the followingtable.
Washer Fluid Con- centration Freezing Temperature
30% 10.4 8F( 12 8C)
50% 48F( 20 8C)
100%
49 8F( 45 8C)
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from
the piping between the reservoir tank and washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside
temperature, it may freeze and block thenozzles.
CAUTION
. Adjust the washer fluid concen-
tration appropriately for the out-
side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.
. State or local regulations on
volatile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle ’s paint, wiper blades
or washer system.

!Before driving your vehicle
Before entering the vehicle, remove any
snow or ice from your shoes because that
could make the pedals slippery anddangerous.
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
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 the “1 ” or “R ”
position for manual transmission models,
or place the select lever in the “P ”position
for automatic transmission 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.
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.
! 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
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
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle ’s braking perfor-

information on braking on slippery sur-
faces, refer to “ABS (Anti-lock Brake
System) ”F 7-22 and “Vehicle Dynamics
