Fuel
CAUTION
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

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. In the circumstances listed below, the vehicle may be more un-
stable than it feels to the driver. The Vehicle Dynamics Control Sys-
tem may therefore operate. Such operation does not indicate a sys-tem fault. on gravel-covered or rutted roads

NOTE
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 nor-
mal. The light will turn off when the engine has reached a suitableoperating temperature. When an engine problem occurs and the CHECK ENGINE
warning light turns on, the VDC OFF indicator light will also turnon. 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.

7-40The 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
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.
