Starting and operating/State emission testing (U.S. only)

lead to fuel spillage and a fire.
. Immediately put fuel in the tank
whenever the low fuel warning
light illuminates. Engine misfires
as a result of an empty tank
could cause damage to the engine.

State emission testing (U.S.
only)
WARNING
Testing of an All-Wheel Drive model
must NEVER be performed on a
single two-wheel dynamometer. Attempting to do so will result in
uncontrolled vehicle movement and
may cause an accident or injuries to
persons nearby.

CAUTION
. At state inspection time, remember to tell your inspection or
service station in advance not to
place your SUBARU AWD vehicle
on a two-wheel dynamometer.
Otherwise, serious transmission
damage will result.
. Resultant vehicle damage due to
improper testing is not covered
under the SUBARU Limited Warranty and is the responsibility of
the state inspection program or
its contractors or licensees.
California and a number of federal states

7-7

have Inspection/Maintenance programs to
inspect your vehicle’s emission control
system. If your vehicle does not pass this
test, some states may deny renewal of
your vehicle’s registration.
Your vehicle is equipped with a computer
that monitors the performance of the
engine’s emission control system. Certified emission inspectors will inspect the
On-Board Diagnostic (OBDII) system as
part of the state emission inspection
process. The OBDII system is designed
to detect engine and transmission problems that might cause the vehicle emissions to exceed allowable limits. OBDII
inspections apply to all 1996 model year
and newer passenger cars and trucks.
Over 30 states plus the District of Columbia have implemented emission inspection of the OBDII system.
. The inspection of the OBDII system
consists of a visual operational check of
the “CHECK ENGINE” warning light/malfunction indicator light (MIL) and an
examination of the OBDII system with an
electronic scan tool.
. A vehicle passes the OBDII system
inspection if proper operation of the
“CHECK ENGINE” warning light is observed, there are no stored diagnostic
trouble codes, and the OBDII readiness
monitors are all complete.
