State emission testing (U.S. only)
Testing of an All-Wheel Drive vehicle must
NEVER be performed on a single two-wheel dy-
namometer. Attempting to do so will result in
uncontrolled vehicle movement and may cause
an accident or injuries to persons nearby.
Resultant vehicle damage due to improper test-
ing is not covered under the SUBARU Limited
Warranty and is the responsibility of the state
inspection program or its contractors or licens-
ees.
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 ve-
hicles. A dynamometer is a treadmill or roller-like test-
ing device that allows your vehicle’s wheels to turn
while the vehicle remains in one place. Depending on
the severity of a state’s air pollution problems, the
states must adopt either a “basic” or “enhanced” vehi-
cle emission inspection test. Normally, 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 more accurate measurement of tailpipe
emitted pollution than the basic emission test.
The U.S. Environmental Protection Agency (EPA) and
states using two-wheel dynamometers in their emis-
sion testing programs have EXEMPTED SUBARU
AWD vehicles from the portion of the testing program
that involves a two-wheel dynamometer.
There are some states that use four-wheel dynamom-
eters in their testing programs. When properly used,
that equipment will not damage an AWD SUBARU ve-
hicle.
Under no circumstances should the rear wheels be
