The U.S. Environmental Protec tion Ag enc y (EPA) and states using two-
wheel d ynamometers in their emission testing p rog ra ms have
EXEMPTED SUBARU AWD vehic les from the p ortion of the testin g p ro-

There are some states that use four-wheel d ynamomet ers in their testing
p rog rams. When p rop erly used , that eq uip ment will n ot d amag e an AWD

Engine exhaust gas (Carbon monoxide)
WARNING
Never inhale engine exhaust gas. Engine exhaust gas contains
carbon monoxide, a colorless and odorless gas which is danger- ous, or even lethal, if inhaled. Always properly maintain the engine exhaust system to pre-
vent engine exhaust gas from entering the vehicle. Never run the engine in a closed space, such as a garage, ex-
cept for the brief time needed to drive the vehicle in or out of it. Avoid remaining in a parked vehicle for a lengthy time while
the engine is running. If that is unavoidable, then use the ventila-tion fan to force fresh air into the vehicle. Always keep the front ventilator inlet grille free from snow,
leaves or other obstructions to ensure that the ventilation system
always works properly.

7-8
If at any time you suspect that exhaust fumes are entering the
vehicle, have the problem checked and corrected as soon as pos-
sible. If you must drive under these conditions, drive only with allwindows fully open. Keep the trunk lid or rear gate closed while driving to prevent
exhaust gas from entering the vehicle.
NOTE Due to the expansion and contraction of the metals used in the
manufacture of the exhaust system, you may hear a crackling soundcoming from the exhaust system for a short time after the enginehas been shut off. This sound is normal.
Catalytic converter
WARNING
Avoid fire hazards. Do not drive or park the vehicle anywhere
near flammable materials (e.g. grass, paper, rags or leaves), be-
cause the catalytic converter operates at very high temperatures. Keep everyone and flammable materials away from the ex-
haust pipe while the engine is running. The exhaust gas is veryhot.
