When driving
■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 recommended dur-
ing 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 when-
ever the fuel level reaches half empty.
WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
●Use tires of the specified size, and that are the same size, same maker,
same brand and tread pattern.
●Maintain the recommended level of air pressure.
●Use snow tires on all, not just some wheels.

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.
