1-5. Refueling
1
Before driving
WARNING
■When refueling
Observe the following precautions to prevent fuel overflowing from the fuel
tank:
●Securely insert the fuel nozzle into the fuel filler neck
●Stop filling the tank after the fuel nozzle automatically clicks off
●Do not top off the fuel tank
●Observe other precautions that are posted at the service station.
●Turn the cap to the right until it clicks to ensure that it is fully tightened. If
the cap is not securely tightened, fuel spillage could occur in the event of
an accident, creating a fire hazard.
■When replacing the fuel cap
Do not use anything but a genuine fuel tank cap designed for your vehicle.
Doing so may cause a fire or other incident which may result in death or seri-
ous injury.
CAUTION
■Refueling
●Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control
system to operate abnormally or damaging fuel system components or the
vehicle's painted surface.
●Never add any cleaning agents to the fuel tank. The addition of a cleaning
agent may cause damage to the fuel system.
●Immediately put fuel in the tank whenever the low fuel warning light illumi-
nates. Engine misfires as a result of an empty tank could cause damage tothe engine.

4-2. Maintenance
Emission inspection and maintenance (I/M) programs
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system moni-
tors the operation of the emission control system.
■If the malfunction indicator lamp comes on
The OBD system determines that a problem exists somewhere
in the emission control system. Your vehicle may not pass the I/
M test and may need to be repaired. Contact your SUBARU
dealer to service the vehicle.
■Your vehicle may not pass the I/M test: ● When the battery is disconnected or discharged
Readiness codes that are set during ordinary driving are
erased.
Also, depending on your driving habits, the readiness codes
may not be completely set.
● When the fuel tank cap is loose
The malfunction indicator lamp comes on as a temporary mal-
function and your vehicle may not pass the I/M test.
■When the malfunction indicator lamp goes off after several
driving trips
The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.
■If your vehicle does not pass the I/M test
Contact your SUBARU dealer to prepare the vehicle for re-test-
ing.

Vehicle specifications
■Gasoline for California-certified LEV
If your vehicle was certified to California’s low emission vehicle (LEV) stan-
dards as indicated on the underhood tune-up label, it is designed to optimize
engine and emission performance with gasoline that meets the clean burn-
ing low-sulfur California gasoline specifications. If you live in any other state
than California, your vehicle will operate on gasoline meeting Federal speci-
fications. Gasoline sold outside California is permitted to have higher sulfur
levels, which may affect the performance of your vehicle’s catalytic converter
and may produce a sulfur exhaust odor or smell. SUBARU recommends that
you try a different brand of unleaded gasoline having lower sulfur to deter-
mine if the problem is fuel related before returning your vehicle to an autho-
rized dealer for service.
■SUBARU recommends the use of gasoline containing detergent addi-
tives
●SUBARU recommends the use of gasoline that contains detergent addi-
tives to avoid build-up of engine deposits.
●All gasoline sold in the US contains detergent additives to clean and/or
keep clean intake systems.
■SUBARU recommends the use of cleaner burning gasoline
Cleaner burning gasoline, including reformulated gasoline that contains oxy-
genates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in
many areas.
SUBARU recommends the use of cleaner burning gasoline and appropri-
ately blended reformulated gasoline. These types of gasoline provide excel-
lent vehicle performance, reduce vehicle emissions and improve air quality.

6-1. Specifications
■SUBARU does not recommend blended gasoline
●If you use gasohol in your SUBARU, be sure that it has an octane rating
no lower than 93 AKI.
●SUBARU DOES NOT recommend the use of gasoline containing metha-
nol.
■SUBARU does not recommend gasoline containing MMT
Some gasoline contains octane enhancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
SUBARU DOES NOT recommend the use of gasoline that contains MMT. If
fuel containing MMT is used, your emission control system may be
adversely affected.
The malfunction indicator lamp on the instrument cluster may come on. If
this happens, contact your SUBARU dealer for service.
●Use only gasoline containing a maxi-
mum of 10% ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 10% etha-
nol, including from any pump labeled
E15, E30, E50, E85 (which are only
some examples of fuel containing more
than 10% ethanol).DO NOT use gasoline
containing more than 10%
ethanol.(15% ethanol)
(50% ethanol)
(85% ethanol)

CAUTION
■Notice on fuel quality
●Do not use improper fuels. If improper fuels are used the engine will be
damaged.
●Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic
converters causing the emission control system to malfunction.
●Do not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance
problems.
●Using unleaded gasoline with an octane number or rating lower than the
level previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■Fuel-related poor driveability
If after using a different type of fuel, poor driveability is encountered (poor
hot starting, vaporization, engine knocking, etc.), discontinue the use of that
type of fuel.
■When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle's paint.
