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.
!MMT
Some gasoline contains an octane-enhan-
cing additive called MMT (Methylcyclo-
pentadienyl 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 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.
!Gasoline for cleaner air
Your use of gasoline with detergent ad-
ditives 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
need to add any fuel system cleaningagents 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 ethanol
(ethyl or grain alcohol) may be used in your
vehicle, but should contain no more than
10% ethanol for the proper operation of
your SUBARU.
Do not use any gasoline that contains
more than 10% ethanol, including from any
pump labeled E15, E30, E50 or E85 (which
are only some examples of fuel containing
more than 10% ethanol).
In addition, some gasoline suppliers are
now producing reformulated gasolines,
which are designed to reduce vehicle
emissions. SUBARU approves the use of
reformulated gasoline.
If you are not sure what the fuel contains,
you should ask your service station op-
erators if their gasolines contain deter-
gents and oxygenates and if they have
been reformulated to reduce vehicle emis-
sions.
As additional guidance, only use fuels
suited for your vehicle as explained in the
following description.
.Fuel should be unleaded and have anoctane rating no lower than that specified
in this manual.
.Methanol (methyl or wood alcohol) is
sometimes mixed with unleaded gasoline.
Methanol can be used in your vehicle
ONLYif it does not exceed 5% of the fuel
mixtureANDif it is accompanied by
sufficient quantities of the proper cosol-
vents and corrosion inhibitors required to
prevent damage to the fuel system. Do not
use fuel containing methanolEXCEPT
under these conditions.
.If undesirable driveability problems are
experienced and you suspect they may be
fuel related, try a different brand of gaso-
line before seeking service at your
SUBARU dealer.
.Fuel system damage or driveability
problems which result from the use of
improper fuel are not covered under the
SUBARU Limited Warranty.
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.

–When the vehicle has been left
parked during a snowstorm
Check for snow or ice buildup on
the suspension, disc brakes and
brake hoses underneath the ve-
hicle. If there is caked snow or
ice, remove it, being careful not
to damage the disc brakes and
brake hoses and ABS harness.
When parking for long periods in cold
weather, you should observe the following
tips.
1. For MT models, place the shift lever in
the“1”or“R”position. For CVT models,
place the select lever in the“P”position.
2. Use tire stops under the tires to prevent
the vehicle from moving.
!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 anti-
freeze 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 thefuel tank filled to capacity.
&Driving on snowy and icy
roadsTo 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-
vior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle’s braking perfor-
mance on snowy and icy roads. For
information on braking on slippery sur-
faces, refer to“ABS (Anti-lock Brake
System)”F7-35 and“Vehicle Dynamics
Control system”F7-37.
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of vehi-
cle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine’sintakesystemandmay
hinder the airflow, which could re-
sult in engine shutdown or even
breakdown.
!Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blade rubbers are not frozen to
the windshield.
If the wiper blade rubbers are frozen to the
windshield, use the defroster and the
temperature set for maximum warmth until
the wiper blade rubbers are completely
thawed. Refer to“Climate control”F4-1.
If your vehicle is equipped with a wiper
deicer, use it. It is helpful to thaw the
windshield wiper blade rubbers. Refer to
“Defogger and deicer”F3-84.
