CHECK ENGINE warning light/Malfunction indicator lamp
CAUTION
If the CHECK ENGINE light comes on while you are driving, have
your vehicle checked/repaired by your SUBARU dealer as soonas possible. Continued vehicle operation without having the
emission control system checked and repaired as necessarycould cause serious damage, which may not be covered by your
vehicle’ s warranty.
If this light comes on steadily or blinks while the engine is running, it may
indicate that there is a problem or potential problem somewhere in the
emission control system. If the light comes on steadily:
If the light comes on steadily while driving or does not go out after the
engine starts, an emission control system malfunction has been de-tected.
You should have your vehicle checked by an authorized SUBARU
dealer immediately. NOTE This light also comes on when the fuel filler cap is not tightened until it clicks.
If you have recently refueled your vehicle, the cause of the CHECK
ENGINE warning light/malfunction indicator lamp coming on could be a
loose or missing fuel filler cap. Remove the cap and retighten it until it
clicks. Make sure nothing is interfering with the sealing of the cap.
Tightening the cap will not make the CHECK ENGINE warning light
turn off immediately. It may take several driving trips. If the light does
not go out, take your vehicle to your authorized SUBARU dealer
immediately. If the light is blinking:
If the light is blinking while driving, an engine misfire condition has
been detected which may damage the emission control system.

7-4In addition, some gasoline suppliers are now producing reformulated
gasolines, which are designed to reduce vehicle emissions. SUBARU
approves the use of reformulated gasoline.
If you are not sure what the fuel contains, you should ask your service station operators if their gasolines contain detergents and oxygenates
and if they have been reformulated to reduce vehicle emissions. As additional guidance, only use fuels suited for your vehicle as ex-
plained below.
Fuel should be unleaded and have an octane rating no lower than
that specified in this manual. Methanol (methyl or wood alcohol) is sometimes mixed with un-
leaded gasoline. Methanol can be used in your vehicle ONLY if it
does not exceed 5% of the fuel mixture AND if it is accompanied by
sufficient quantities of the proper cosolvents and corrosion inhibitors
required to prevent damage to the fuel system. Do not use fuel con-
taining methanol EXCEPT under these conditions.
If undesirable driveability problems are experienced and you sus-
pect they may be fuel related, try a different brand of gasoline before
seeking service at your SUBARU dealer. Fuel system damage or driveability problems which result from the
use of improper fuel are not covered under the SUBARU Limited War-
ranty.
Fuel filler lid and cap Refueling
WARNING
Gasoline vapor is highly flammable. Before refueling, always
first stop the engine and make sure that there are no lighted ciga- rettes, open flames or electrical sparks in the adjacent area. When opening the cap, do not remove the cap quickly. Fuel
may be under pressure and spray out of the fuel filler neck espe-
cially in hot weather, which may cause injury.

CAUTION
Never add any cleaning agents to the fuel tank. The addition of
a cleaning agent may cause damage to the fuel system. Make sure that the cap is tightened until it clicks to prevent
fuel spillage in the event of an accident. Do not let fuel spill on the exterior surfaces of the vehicle.
Fuels may cause paint damage, which is not covered under the
SUBARU Limited Warranty. Always use a genuine SUBARU fuel filler cap. If you use the
wrong cap, it may not fit or have proper venting, and your fueltank and emission control system might be damaged.

2. Remove the fuel filler cap by turning it slowly counterclockwise.
3. Stop filling the tank after the fuel filler pump automatically clicks off.
Do not add any more fuel.
4. Put the cap back on, turn it clockwise until you hear a clicking
noise. Be certain not to catch the tether under the cap while tighten-ing.
5. Close the fuel filler lid completely.
If you spill any fuel on the painted surface, rinse it off immediately.
Otherwise, the painted surface could be damaged. NOTE

You will see the “FUEL DOOR p” sign in the combination
meter. This indicates that the fuel filler door (lid) is located on the right side of the vehicle.

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

8-12When the vehicle has been left parked after use on roads heavily cov-
ered with snow, or has been left parked during a snowstorm, icingmay 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 harness. n
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 recom-
mended 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
WARNING
Do not use the cruise control on slippery roads such as snowy or icy roads. This may cause loss of vehicle control.
To prevent skidding and slipping, avoid sudden braking, abrupt ac-
celeration, high-speed driving, and sharp turning when driving on
snowy or icy roads.Always maintain ample distance between your vehicle and the vehicleahead of you to avoid the need for sudden braking.
To supplement the foot brake, use the engine brake effectively to con-
trol the vehicle speed. (Shift into a lower gear when necessary.)
Avoid shifting down abruptly. Such behavior can cause the wheels to
lock, possibly leading to loss of vehicle control.
An anti-lock brake system (ABS) enhances your vehicle ’s braking per-
formance on snowy and icy roads. Refer to the “ABS (Anti-Lock Brake
System)” and “VDC (Vehicle Dynamics Control) system ” section in
chapter 7 for information on braking on slippery surfaces.
