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
The engine is designed to operate using
unleaded gasoline with an octane rating
of 87 AKI (90 RON) or higher .
! 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. Contact
your SUBARU dealer 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 light may also
illuminate. 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. !
MMT
Some gasoline contains an octane-en-
hancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl). If
you use such fuels, your emission control
system performance may deteriorate and
the CHECK ENGINE warning light/Mal-
function indicator light may illuminate. If
this happens, return to your authorized
SUBARU dealer for service. If it is
determined that the condition is caused
by the type of fuel used, repairs may not
be covered by your warranty. ! Gasoline for cleaner air
CAUTION
Do not let fuel spill on the exterior
surfaces of the vehicle. Fuels con-
taining alcohol may cause paint
damage, which is not covered under
the SUBARU Limited Warranty.
Your use of gasoline with detergent
additives will help prevent deposits from
forming in your engine and fuel system.
This helps keep your engine in tune and
your emission control system working
properly, and is a way of doing your part
for cleaner air. If you continuously use a
high quality fuel with the proper detergent
and other additives, you should never

could make the pedals slippery and
driving dangerous.
While warming up the vehicle before
driving, check that the accelerator pedal,
brake pedal, and all other controls operate
smoothly.
Clear away ice and snow that has
accumulated under the fenders to avoid
making steering difficult. During severe
winter driving, stop when and where it is
safe to do so and check under the fenders
periodically. !Parking in cold weather
WARNING
Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle if you park
the vehicle in snow with the enginerunning.
Do not use the parking brake when
parking for long periods in cold weather
since it could freeze in that position.
Instead, you should observe the followingtips.
1. Place the select lever in “P ”position.
2. Use tire stops under the tires to
prevent the vehicle from moving. When the vehicle is parked in snow or
when it snows, raise the wiper blades off
the glass to prevent damage to them.
When the vehicle has been left parked
after use on roads heavily covered with
snow, or has been left parked during a
snowstorm, icing may develop on the
brake system, which could cause poor
braking action. Check for snow or ice
buildup on the suspension, disc brakes
and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it,
being careful not to damage the disc
brakes and brake hoses and ABS har-ness. !
Refueling in cold weather
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an
antifreeze additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty.
If your SUBARU is not going to be used
for an extended period, it is best to have
the fuel tank filled to capacity. &
Driving on snowy and icy roads
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of
vehicle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine ’s intake system and may
hinder the airflow, which could re-
sult in engine shutdown or evenbreakdown.
To prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you
to avoid the need for sudden braking.
To supplement the foot brake, use the
engine brake effectively to control the
vehicle speed. (Shift into a lower gear
when necessary.)
Avoid shifting down abruptly. Such beha- Driving tips
