Starting and operating
Do not let fuel spill on the exterior surfaces of
the vehicle. Fuels may cause paint damage,
which is not covered under the SUBARU Limit-
ed 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 fuel tank and emis-
sion control system might be damaged.
State emission testing (U.S. only)
At state inspection time, remember to tell your in-
spection or service station in advance not to place
your SUBARU AWD vehicle on a two-wheel dyna-
mometer. Otherwise, serious transmission dam-
age will result.
Some states have started using dynamometers in
their state inspection programs in order to meet their
obligation under federal law to implement stricter vehi-
cle 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 in-
spection test. Normally, a portion of the basic emission
test consists of an emission inspector inserting an an-
alyzer 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 driv-
ing conditions on a dynamometer and permits more
accurate measurement of tailpipe emitted pollution
than the basic emission test.
