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. T MMT
Some gasoline contains an octane-enhancing additive
called MMT (Methylcyclopentadienyl Manganese Tri-
carbonyl). If you use such fuels, your emission control
system performance may de teriorate 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 yo ur engine in tune and your
emission control system work ing 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 ap
proves the use of re-
formulated gasoline.
If you are not sure what the fuel contains, you should
ask your service station oper ators if their gasoline con-
tains detergents and oxy genates and if they have
been reformulated to reduce vehicle emissions.
As additional guidance, only use fuels suited for your
vehicle as explained in the following. 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 accomp anied by sufficient
quantities of the proper cosolvent and corrosion inhib-

Driving tips

severe winter driving, stop when and where it is safe
to do so and check under the fenders periodically. TParking in cold weather
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 engine running.
Do not use the parking brake when parking for long
periods in cold weather since it could freeze in that po-
sition. Instead, observe the following.
1. Place the shift lever in “1” or “R” for manual trans-
mission vehicles, and in “P” for automatic transmission vehicles.
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 harness. T
Refueling in cold weather
To help prevent moisture from forming in the fuel sys-
tem and the risk of its freez ing, 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.
