2010 SUBARU OUTBACK catalytic converter

7-2Starting and operating
Fuel
CAUTION
Use of a fuel which is low in quality
or use of an inappropriate fuel
additive may cause engine damage.
& Fuel requirements
! Non-turbo models
The non-turbo engine is designed to
operate using unleadedgasoline with an
octane rating of 87 AKI or higher .
! Turbo models
The engine is designed to operate at
maximum performance using unleaded
gasoline with an octane rating of 93 AKI
or higher . If 93 AKI fuel is not readily
available in your area, unleaded gasoline
with an octane rating of 91 AKI may be
used with no detriment to engine durability
or driveability. However, you may notice a
slight decrease in maximum engine per-
formance while using 91 AKI fuel. Use of
91 AKI fuel will not affect your warranty
coverage. If premium unleaded gasoline is
not available, regular unleaded gasoline
with an octane rating of 87 AKI or higher
may be temporarily used. For optimum engine performance and driveability, it is
required that you use premium grade
unleaded gasoline.
NOTE
Be sure to use premium unleaded
gasoline of 91 AKI or higher for a turbo
engine model. If other gasoline (lower
than 91 AKI) is used, knocking, re-
duced output and poor accelerator
response will result. ! Fuel octane rating
This octane rating is the average of the
Research Octane and Motor Octane
numbers and is commonly referred to as
the Anti Knock Index (AKI).
Using a gasoline with a lower octane
rating can cause persistent and heavy
knocking, which can damage the engine.
Do not be concerned if your vehicle
sometimes knocks lightly when you drive
up a hill or when you accelerate. See your
dealer or a qualified service technician if
you use a fuel with the specified octane
rating and your vehicle knocks heavily or
persistently. ! Unleaded gasoline
The neck of the fuel filler pipe is designed
to accept only an unleaded gasoline filler
nozzle. Under no circumstances should
leaded gasoline be used because it will damage the emission control system and
may impair driveability and fuel economy. !
California fuel
If your vehicle was certified to California
Emission Standards as indicated on the
underhood tune-up label, it is designed to
optimize engine and emission control
system performance with gasoline that
meets the clean burning low-sulfur Cali-
fornia gasoline specifications. If you live in
any other state than California, your
vehicle will operate on gasoline meeting
Federal specifications. Gasoline sold out-
side California is permitted to have higher
sulfur levels, which may affect the perfor-
mance of your vehicle ’s catalytic converter
and may produce a sulfur exhaust odor or
smell. SUBARU recommends that you try
a different brand of unleaded gasoline
having lower sulfur to determine if the
problem is fuel related before returning
your vehicle to an authorized dealer for
service. The CHECK ENGINE warning
light/malfunction indicator lamp may also
turn on. If this occurs, return to your
authorized SUBARU dealer for diagnosis.
If it is determined that the condition is
caused by the type of fuel used, repairs
may not be covered by your warranty.

exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open.
. Keep the trunk lid (Legacy) or
rear gate (Outback) 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 sound coming from the ex-
haust system for a short time after the
engine has been shut off. This sound isnormal. Catalytic converter
WARNING
. Avoid fire hazards. Do not drive
or park the vehicle anywhere
near flammable materials (e.g.
grass, paper, rags or leaves),
because the catalytic converter
operates at very high tempera-tures.
. Keep everyone and flammable
materials away from the exhaust
pipe while the engine is running.
The exhaust gas is very hot.

The catalytic converter is installed in the
exhaust system. It serves as catalyst to
reduce HC, CO and NOx in exhaust
gases, thus providing cleaner exhaust. Driving tips

8-4Driving tips
To avoid damage to the catalytic conver- ter: .Use only unleaded gasoline. Even a
small amount of leaded gasoline will
damage the catalytic converter. . Never start the engine by pushing or
pulling the vehicle.. Avoid racing the engine.
. Never turn off the ignition switch while
the vehicle is moving.. Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), have
your vehicle checked and repaired by an
authorized SUBARU dealer. . Do not apply undercoating or rust
prevention treatment to the heat shield of
catalytic converter and the exhaust sys-tem. . Do not drive with an extremely low fuel
level. Periodic inspections
To keep your vehicle in the best condition
at all times, always have the recom-
mended maintenance services listed in
the maintenance schedule in the
“War-
ranty and Maintenance Booklet ”per-
formed at the specified time or mileageintervals. Driving in foreign countries
When planning to use your vehicle in
another country: .
Confirm the availability of the correct
fuel. Refer to “Fuel requirements ”F 7-2.
. Comply with all regulations and re-
quirements of each country.
