FuelCAUTION
Use of a fuel which is low in quality or use of an inappropriate fuel additive may cause engine damage.
Fuel requirements 2.5 Liter models
The 2.5 Liter engine is designed to operate using unleaded gasoline
with an octane rating of 87 AKI or higher. 3.0 Liter models
The 3.0 Liter engine is designed to operate using premium unleaded
gasoline with an octane rating of 91 AKI or higher. Regular unleaded
gasoline with an octane rating of 87 AKI may be used if necessary.
For optimum engine performance and driveability, it is recommended
that you use premium grade unleaded gasoline. Fuel octane rating
This octane rating is the average of the Research Octane and Motor
Octane numbers and is commonly referred to as the Anti Knock Index(AKI).Using a gasoline with a lower octane rating can cause persistent and
heavy knocking, which can damage the engine. Do not be concerned
if your vehicle sometimes knocks lightly when you drive up a hill or
when you accelerate. See your dealer or a qualified service techni-
cian if you use a fuel with the specified octane rating and your vehicle
knocks heavily or persistently. Unleaded gasoline
The neck of the fuel filler pipe is designed to accept only an unleaded
gasoline filler nozzle. Under no circumstances should leaded gaso-
line be used because it will damage the emission control system and
may impair driveability and fuel economy.

If the fuel filler cap is not tightened until it clicks or if the tether
is caught under the cap, the CHECK ENGINE warning light may come on. Refer to the “Warning and indicator lights ” section lo-
cated in chapter 3.
State emission testing (U.S. only)
WARNING
Testing of an All-Wheel Drive vehicle must NEVER be performed
on a single two-wheel dynamometer. Attempting to do so willresult in uncontrolled vehicle movement and may cause an acci-
dent or injuries to persons nearby.
CAUTION
Resultant vehicle damage due to improper testing is not covered
under the SUBARU Limited Warranty and is the responsibility ofthe state inspection program or its contractors or licensees.
At state inspection time, remember to tell your inspection or service
station in advance not to place your Subaru AWD vehicle on a two-
wheel dynamometer. Otherwise, serious transmission damage willresult.
Some states have started using dynamometers in their state inspection
programs in order to meet their obligation under federal law to implement
stricter vehicle emission standards to reduce air pollution from cars. A
dynamometer is a treadmill or roller-like testing device that allows your
car’ s wheels to turn while the car remains in one place. Depending on
the severity of a state ’s air pollution problems, the states must adopt
either a “basic” or “enhanced” vehicle emission inspection test. Nor-
mally, a portion of the basic emission test consists of an emission
inspector inserting an analyzer probe into the exhaust pipe of an idling
vehicle for a short period of time. States with more severe air pollution
problems are required to adopt an enhanced vehicle emission test. This
test simulates actual driving conditions on a dynamometer and permits

leave ample distance from other vehicles. When you feel the ABS system operating, you should maintain
constant brake pedal pressure. 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 slippery road surfaces. This helps prevent
the loss of steering control and directional stability caused by wheellock-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 ABSoperates. 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 compartment 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 abnormal condition. ABS warning light
HB4010GA
The ABS warning light comes on when the ignition switch is turned to the “ON” position and goes out after about two seconds.

In the event of wheelspin and/or skidding on a slippery road surface
and/or during cornering and/or an evasive maneuver, the VDC systemadjusts 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 bysteady illumination of the VDC 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 dur-
ing steering operations. Activation of this function is shown by flash-ing of the VDC operation indicator light.
NOTE Slight twitching of the brake pedal may be felt when the VDC-sys-
tem operates; a small degree of vehicle or steering wheel shaking may also be noticed in this situation. These are normal characteris-tics of VDC operation and are no cause for alarm. When driving off immediately after starting the engine, a short-
lived operation noise may be noticed coming from the enginecompartment. This noise is generated as a result of a check beingperformed on the VDC system and is normal. Depending on the timing of activation of the brakes, certain situa-
tions may occur just after driving off where the brake pedal seemsto exhibit a jolting motion. This too is a consequence of the VDCoperational check and is normal. Activation of the VDC system will cause operation of the steering
wheel to feel slightly different compared to that for normal condi-tions. Even if the vehicle is equipped with a VDC system, it is important
that winter tires be used when driving on snow-covered or icyroads. (All four wheels should be fitted with tires of the same sizeand brand).

warning light turns on, the VDC OFF indicator light will also turn on. The following two situations could indicate malfunction of the VDC
system; if either should occur, have an authorized SUBARU dealer
carry out an inspection of that system at the first available opportunity.The VDC OFF indicator light does not turn on when the ignition key
is turned to the ON position. 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. n VDC operation indicator light
The VDC operation indicator light turns on when the ignition key is
turned to the ON position; it turns off approximately two seconds later.
This indicator light flashes during activation of the skid suppression
function and is illuminated steadily during activation of the traction
control function. The following two situations could indicate a malfunction of the VDC
system; if either should occur, have an authorized SUBARU dealer
carry out an inspection of that system at the first available opportunity. The VDC operation indicator light does not turn on when the igni-
tion key is turned to the ON position. The VDC operation indicator light does not turn off approximately
two seconds after the ignition key has been turned to the ON position. n VDC warning light
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. The following situations could indicate a malfunction of the VDC sys-
tem; if any should occur, have an authorized SUBARU dealer carry
out an inspection of the system at the first available opportunity. The VDC warning light does not turn on when the ignition key is
turned to the ON position. The VDC warning light does not turn off either when the engine is

7-30
started or when the vehicle reaches a speed of approximately 8 mph (12 km/h).The VDC warning light turns on while the vehicle is being driven.
When a malfunction has occurred in the VDC electrical system,
only the VDC warning light will turn on. In such an event, the ABS will
still be operating normally. The VDC warning light will also turn on when a problem occurs
with the ABS or VDC electronic control systems.
Because the VDC system controls each brake through the ABS,
whenever the ABS stops operating due to a malfunction in that electri-
cal system, the VDC will also become unable to control all four
brakes. Thus VDC system operation halts and the VDC warning light
turns on. Although both the VDC system and the ABS will be inoper-able in this situation, it will still be possible to stop the vehicle using
normal braking. The VDC system and the ABS do not adversely affect
operation of the vehicle in any way when they are inoperable; how-
ever should such a situation occur, drive with care and have an autho-
rized SUBARU dealer carry out an inspection of those systems at the
first available opportunity. NOTE
When the VDC warning light turns on and off in the following way,
it indicates that the VDC 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 after the engine is started and does
not turn off until the vehicle reaches a speed of 8 mph (12 km/h). The warning light turns on when the vehicle is being driven; it
then turns off and stays off.

Cruise control lever
1. Push the “CRUISE” main switch. The indicator light on the switch
will come on.
2. Depress the accelerator pedal until the vehicle reaches the de-
sired speed.
3. Push the control lever downward in the “SET, COAST ” direction
and release it. Then release the accelerator pedal.
The vehicle will maintain the desired speed.
Vehicle speed can be temporarily increased while driving with the
cruise control activated. Simply depress the accelerator pedal to ac-
celerate the vehicle. When the accelerator pedal is released, the ve-
hicle will return to and maintain the previous cruising speed. To temporarily cancel the cruise control
There are four ways to cancel the cruise control temporarily:
Depress the brake pedal.
Pull the control lever in the “CANCEL” direction. (if so equipped)
Depress the clutch pedal (manual transmission vehicles only).
Shift the selector lever into the “N” position (automatic transmis-
sion vehicles only).
To resume the cruise control after it has been temporarily canceled
and with vehicle speed of about 20 mph (32 km/h) or more, push the
control lever upward in the “ACCEL, RESUME ” direction to return to
the original cruising speed automatically.

nDriving with a trailer
You should allow for considerably more stopping distance when
towing a trailer. Avoid sudden braking because it may result in skid-
ding or jackknifing and loss of control. Avoid abrupt starts and sudden accelerations. If your vehicle has a
manual transmission, always start out in first gear and release the
clutch at moderate engine revolution. Avoid uneven steering, sharp turns and rapid lane changes.
Slow down before turning. Make a longer than normal turning
radius because the trailer wheels will be closer than the vehicle
wheels to the inside of the turn. In a tight turn, the trailer could hit yourvehicle. Crosswinds will adversely affect the handling of your vehicle and
trailer, causing sway. Crosswinds can be due to weather conditions or
the passing of large trucks or buses. If swaying occurs, firmly grip the
steering wheel and slow down immediately but gradually. When passing other vehicles, considerable distance is required
because of the added weight and length caused by attaching the
trailer to your vehicle. Backing up with a trailer is difficult and takes practice. When back-
ing up with a trailer, never accelerate or steer rapidly. When turning
back, grip the bottom of the steering wheel with one hand and turn it
to the left for a left turn, and turn it to the right for a right turn.

NOTE
[Automatic transmission vehicle not equipped with VDC (Vehicle Dy-
namics Control)] Before driving your vehicle with the temporaryspare tire, put a spare fuse inside the FWD connector located in theengine compartment and confirm that the Front-wheel drive warninglight comes on. The all wheel drive capability of the vehicle has now
been deactivated. After re-installing the conventional tire, removethe spare fuse from the FWD connector in order to reactivate allwheel drive.
Flat tires
WARNING
Do not jack up the vehicle on an incline or a loose road sur-
face. The jack can come out of the jacking point or sink into the ground and this can result in a severe accident. Use only the jack provided with your vehicle. The jack sup-
plied with the vehicle is designed only for changing a tire. Neverget under the vehicle while supporting the vehicle with this jack. Always turn the engine off before raising the flat tire off the
ground using the jack. Never swing or push the vehicle sup-ported with the jack. The jack can come out of the jacking pointdue to a jolt and this can result in a severe accident.

Corrosion protection
Your SUBARU has been designed and built to resist corrosion. Special
materials and protective finishes have been used on most parts of the
vehicle to help maintain fine appearance, strength, and reliable opera-tion. Most common causes of corrosion
The most common causes of corrosion are:
1. The accumulation of moisture retaining dirt and debris in body
panel sections, cavities, and other areas.
2. Damage to paint and other protective coatings caused by graveland stone chips or minor accidents.
Corrosion is accelerated on the vehicle when:
1. It is exposed to road salt or dust control chemicals, or used in
coastal areas where there is more salt in the air, or in areas where
there is considerable industrial pollution.
2. It is driven in areas of high humidity, especially when temperatures
range just above freezing.
3. Dampness in certain parts of the vehicle remains for a long time,
even though other parts of the vehicle may be dry.
4. High temperatures will cause corrosion to parts of the vehicle
which cannot dry quickly due to lack of proper ventilation. To help prevent corrosion
Wash the vehicle frequently. If you drive on salted roads in the winter
or if you live in a coastal area, you should flush the underbody with
fresh water frequently.
After the winter has ended, it is recommended that the underbody be
given a very thorough washing.
