WARNING
■
Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery.
● Make sure the jumper cable is connected to the correct terminal and that it
is not unintentionally in contact with any part other than the intended termi-
nal.
● Do not allow the jumper cables to come into contact with the “+” and “-” ter-
minals.
● Do not allow open flame or use matches, cigarette lighters or smoke near
the battery.
■ Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery.
● When working with the battery, always wear safety glasses and take care
not to allow any battery fluids (acid) to come into contact with skin, clothing
or the vehicle body.
● Do not lean over the battery.
● In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
● Always wash your hands after handling the battery support, terminals, and
other battery-related parts.
● Do not allow children near the battery.
■ To prevent damage to the vehicle
Do not pull- or push-start the vehicle as the three-way catalytic converter
may overheat and become a fire hazard.

■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 oper ate 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 refo rmulated gasoline that contains oxy-
genates such as ethanol 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.

CAUTION
■Notice on fuel quality
●Do not use improper fuels. If improper fuels are used the engine and/or
fuel system 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.
