check the operation of the warning and indicator lights.
Refer to the “Warning and indicator lights” section
(chapter 3).
5. Turn the ignition switch to the “START” position
without depressing the accelerator pedal. Release
the key immediately after the engine has started.
If the engine does not start within ten seconds, wait a
while and then turn the ignition switch to the “START”
position again while depressing the accelerator pedal
half way down.
6. Confirm that all warning and indicator lights have
gone out after the engine has started. The fuel injec-
tion system automatically lowers the idle speed as the
engine warms up.
While the engine is warming up, make sure that the
selector lever is at the “P” or “N” position and that the
parking brake is applied. „ Starting the engine during cold weath- er below –4 °F (–20 °C)
If the engine is difficult to start using the normal meth-
od (without depressing the accelerator pedal), turn the
ignition switch to the “START” position while slightly
depressing the accelerator pedal. „
Starting a flooded engine
If the engine does not start, it may be flooded (exces-
sive fuel in the engine).
In case of a flooded engine, turn the starter motor for
five seconds with the accelerator pedal fully de-
pressed. Repeat this two or three times until the en-
gine starts. Release the ignition switch and accelera-
tor pedal as soon as the engine starts.

ABS (Anti-lock Brake System)
Always use the utmost care in driving – over-
confidence because you are driving with an
ABS equipped vehicle could easily lead to a se-
rious accident.
y
The ABS system does not always decrease
stopping distance. You should always maintain
a safe following distance from other vehicles. y When driving on badly surfaced roads, gravel
roads, icy road, or over deep newly fallen snow,
stopping distances may be longer for a vehicle
with the ABS system than one without. When
driving under these conditions, therefore, re-
duce your speed and leave ample distance from
other vehicles. y When you feel the ABS system operating,
you should maintain constant brake pedal pres-
sure. Do not pump the brake pedal since doing
so may defeat the operation of the ABS system. The ABS system prevents the lock-up of wheels which
may occur during sudden braking or braking on slip-
pery road surfaces. This helps prevent the loss of
steering control and directional stability caused by
wheel lock-up.
When the ABS system is operating, you may hear a
chattering noise or feel a slight vibration in the brake
pedal. This is normal when the ABS operates.
The ABS system will not operate when the vehicle
speed is below approximately 6 mph (10 km/h). „
ABS system self-check
You may feel a slight shock in the brake pedal and hear the operating sound of ABS from the engine com-
partment just after the vehicle is started. This is
caused by an automatic functional test of the ABS sys-
tem being carried out and does not indicate any abnor-
mal condition.

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

Starting and operating
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.
The Vehicle Dynamics Control System may there-
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

yThis light turns on to indicate that the VDC system
is in non-operation mode. This does not constitute fail- ure of the VDC system.
NOTE y The VDC OFF indicator light may stay 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 temperature. y When an engine problem occurs and the CHECK
ENGINE warning light turns on, the VDC OFF indi-
cator light will also turn on.
The following two situations could indicate malfunction
of the VDC system; if either should occur, have an au-
thorized SUBARU dealer carry out an inspection of
that system at the first available opportunity. y The VDC OFF indicator light does not turn on when
the ignition key is turned to the ON position. y The VDC OFF indicator light fails to turn off after the
engine is started, even when several minutes have
passed to allow the engine to heat up sufficiently. T VDC operation indicator light
The VDC operation indicator light turns on when the
ignition key is turned to the ON position; it turns off ap- proximately two seconds later. This indicator light
flashes during activation of the skid suppression func-
tion and is illuminated steadily during activation of the
traction control function.
The following two situations could indicate a malfunc-
tion of the VDC system; if either should occur, have an
authorized SUBARU dealer carry out an inspection of

The VDC warning light turns on when the ignition key
is turned to the ON position and off when the engine is
started. This lighting pattern indicates that the VDC
system is operating normally.

Driving tips
y
Always check your brakes for effectiveness immedi-
ately after driving in sand, mud or water. Do this by
driving slowly and stepping on the brake pedal. Re-
peat that process several times to dry out the brake
discs and brake pads.y Do not drive or park over or near flammable materi-
als 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. y 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 under-
body. If the vehicle is used with these materials
trapped or adhering to the underbody, a mechanical
breakdown or fire could occur.y 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 totip over. y If you must rock the vehicle to free it from 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 pos-
sible traction, avoid spinning the wheels when trying to
free the vehicle. y
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). y Never equip your vehicle with tires larger than those
specified in this manual. y Wash the vehicle’s underbody after off-road driving.
Suspension components are particularly prone to dirt
buildup, so they need to be washed thoroughly.y Frequent driving of an AWD vehicle under hard-driv-
ing conditions such as rough roads or off roads will ne-
cessitate more frequent replacement of engine oil,
brake fluid and transmission oil than that specified in
the maintenance schedule described in the “Warranty
and Maintenance Booklet”.
Remember that damage done to your SUBARU while
operating it off-road and not using common sense pre-
cautions such as those listed above is not eligible for
warranty coverage.

Appearance care
„
Cleaning aluminum wheels
y Promptly wipe the aluminum wheels clean of any
kind of grime or agent. If dirt is left on too long, it may
be difficult to clean off.y Do not use soap containing grit to clean the wheels.
Be sure to use a neutral cleaning agent, and later rinse
thoroughly with water. Do not clean the wheels with a
stiff brush or expose them to a high-speed washing
device. y Clean the vehicle (including the aluminum wheels)
with water as soon as possible when it has been
splashed with sea water, exposed to sea breezes, or
driven on roads treated with salt or other agents. „

7. Slide the cover toward the vehicle front to remove it.
8. Remove the oil filter with an oil filter wrench.
9. Before installing a new oil filter, apply a thin coat of
engine oil to the seal.
10.Clean the rubber seal seating area of the bottom of
engine and install the oil filter by hand turning. Be
careful not to twist or damage the seal.
11.Tighten it approximately two-thirds of a turn after
the seal makes contact with the bottom of engine.
Never over tighten the oil filter because that can
result in an oil leak.
12.Reinstall the cover under the oil filter.
13.Pour engine oil through the filler neck.
Oil capacity (Guideline): 2.5 liter models: 4.2 US qt (4.0 liters, 3.5 Imp qt)
3.0 liter models: 5.6 US qt (5.3 liters, 4.6 Imp qt)
The oil quantity indicated above is only a guideline.
The necessary quantity of oil depends on the quantity
of oil that has been drained. The quantity of drained oil
differs slightly depending on the temperature of the oil
and the time the oil is left flowing out. After refilling the
engine with oil, therefore, you must use the dipstick to
confirm that the level is correct.
14.Start the engine and make sure that no oil leaks ap-
pear around the filter’s rubber seal and drain plug.
15.Run the engine until it reaches the normal operat-
ing temperature. Then stop the engine and wait a few
minutes to allow the oil drain back. Check the oil level
again and if necessary, add more engine oil.
