California is permitted to have higher sulfur levels,
which may affect the performance 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 sul-
fur to determine if the problem is fuel related before re-
turning your vehicle to an authorized dealer for ser-
vice. TMMT
Some gasoline contains an octane-enhancing additive
called MMT (Methylcyclopentadienyl Manganese Tri-
carbonyl). If you use such fuels, your emission control
system performance may deteriorate and the CHECK
ENGINE warning light/Malfunction indicator lamp may
turn on. 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. T Gasoline for cleaner air
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 continu-
ously use a high quality fuel with the proper detergent
and other additives, you should never need to add any fuel system cleaning agents to your fuel tank.
Many gasolines are now blended with materials called
oxygenates. Use of these fuels can also help keep the
air cleaner. Oxygenated blend fuels, such as MTBE
(Methyl Tertiary Butyl ether) or ethanol (ethyl or grain
alcohol) may be used in your vehicle, but should con-
tain no more than 15% MTBE or 10% ethanol for the
proper operation of your SUBARU.
In addition, some gasoline suppliers are now produc-
ing reformulated gasoline, which is designed to reduce
vehicle emissions. SUBARU approves the use of re-
formulated gasoline.
If you are not sure what the fuel contains, you should
ask your service station operators if their gasoline con-
tains detergents and oxygenates and if they have
been reformulated to reduce vehicle emissions.
As additional guidance, only use fuels suited for your
vehicle as explained below. y
Fuel should be unleaded and have an octane rating
no lower than that specified in this manual. y Methanol (methyl or wood alcohol) is sometimes
mixed with unleaded gasoline. Methanol can be used
in your vehicle ONLY if it does not exceed 5% of the
fuel mixture AND if it is accompanied by sufficient
quantities of the proper cosolvent and corrosion inhib-

Driving tips
– CONTINUED –
If there is caked snow or ice, remove it, being careful
not to damage the disc brakes and brake hoses andABS harness. TRefueling in cold weather
To help prevent moisture from forming in the fuel sys-
tem and the risk of its freezing, use of an antifreeze ad-
ditive 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 extend-
ed period, it is best to have the fuel tank filled to capac-
ity. „ Driving on snowy and icy roads
Do not use the cruise control on slippery roads
such as snowy or icy roads. This may cause
loss of vehicle control.
To prevent skidding and slipping, avoid sudden brak- ing, 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 sud-
den 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 behavior can
cause the wheels to lock, possibly leading to loss of
vehicle control.
An anti-lock brake system (ABS) enhances your vehi-
cle’s braking performance on snowy and icy roads.
Refer to the “ABS (Anti-lock Brake System)” section in
chapter 7 for information on braking on slippery sur- faces. T
Wiper operation when snowing
Before driving in cold weather, make sure the wiper
blades are not frozen to the windshield or rear window.
If the wiper blades are frozen to the windshield or rear
window, use the defroster with the airflow control dial
in the “ ” position and the temperature control dial
set for maximum warmth until the wiper blades are
completely thawed out. If your vehicle is equipped with
a wiper deicer, it is helpful to thaw the windshield wiper
blades.
