Emission inspection and maintenance (I/M) programs
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system moni-
tors the operation of the emission control system.
■If the malfunction indicator lamp comes on
The OBD system determines that a problem exists somewhere
in the emission control system. Your vehicle may not pass the I/
M test and may need to be repaired. Contact your SUBARU
dealer to service the vehicle.
■Your vehicle may not pass the I/M test:
●When the battery is disconnected or discharged
Readiness codes that are set during ordinary driving are
erased.
Also, depending on your driving habits, the readiness codes
may not be completely set.
●When the fuel tank cap is loose
The malfunction indicator lamp comes on as a temporary mal-
function and your vehicle may not pass the I/M test.
■When the malfunction indicator lamp goes off after several
driving trips
The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.
■If your vehicle does not pass the I/M test
Contact your SUBARU dealer to prepare the vehicle for re-test-
ing.

Maintenance and care
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■When working in the engine compartment
●Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■When working near the electric cooling fans or radiator grille
Vehicles without a keyless access with push button start system: Be sure the
engine switch is off. With the engine switch in the “ON” position, the electric
cooling fans may automatically start to run if the air conditioning is on and/or
the coolant temperature is high. (oP. 342)
Vehicles with a keyless access with push button start system: Be sure the
push-button ignition switch is off. With the push-button ignition switch in
“ON” mode, the electric cooling fans may automatically start to run if the air
conditioning is on and/or the coolant temperature is high. (oP. 342)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
CAUTION
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air. Also a backfire could cause a fire in the engine compart-
ment.

Maintenance and care
WARNING
■Pre-driving check
Check that the engine hood is fully closed and locked.
If the engine hood is not locked properly it may open while the vehicle is in
motion and cause an accident, which may result in death or serious injury.
CAUTION
■When opening the engine hood
●Do not lift up or operate the wipers. Doing so may cause the engine hood
and wipers to contact, scratching the engine hood.
●Use caution when opening the engine hood in windy weather as it may
close suddenly in strong wind.
●Do not attach any accessories other than genuine SUBARU products to
the engine hood. Such additional weight on the engine hood may cause it
to be too heavy to be supported by the supporting rod when opened.
■When closing the engine hood
Do not apply excessive weight or force when closing the engine hood as
doing so may result in damage.

Engine oil
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
■Checking the engine oil
Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than five minutes for the oil to
drain back into the bottom of the engine.
Hold a rag under the end and
pull the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully.
Holding a rag under the end, pull the dipstick out and check
the oil level.
When checking the oil, look at both sides of the dipstick and use the
lower measurement to determine the level of oil.
Wipe the dipstick and reinsert it fully.
