Fuel
CAUTION
Use of a fuel which is low in qualityor use of an inappropriate fueladditive may cause engine damage.
&Fuel requirements
The engine is designed to operate usingunleaded gasolinewith an octane ratingof87 AKI (90 RON) or higher.
!Fuel octane rating
This octane rating is the average of theResearch Octane and Motor Octanenumbers andis commonly referred to asthe Anti Knock Index (AKI).
Using a gasoline with a lower octanerating can causepersistent and heavyknocking, which can damage the engine.Do not be concerned if your vehiclesometimes knocks lightly when you driveup a hill or when you accelerate. Contactyour SUBARU dealer if you use a fuel withthe specified octane rating and yourvehicle knocks heavily or persistently.
!Unleaded gasoline
The neck of the fuel filler pipe is designedto accept only an unleaded gasoline filler
nozzle. Under no circumstances shouldleaded gasoline be used because it willdamage the emission control system andmay impair driveability and fuel economy.
!California fuel
If your vehicle was certified to CaliforniaEmission Standards as indicated on theunderhood tune-up label, it is designed tooptimize engine and emission controlsystem performance with gasoline thatmeets the clean burning low-sulfur Cali-fornia gasoline specifications. If you live inany other state than California, yourvehicle will operate on gasoline meetingFederal specifications. Gasoline sold out-side California is permitted to have highersulfur levels, which may affect the perfor-mance of your vehicle’s catalytic converterand may produce a sulfur exhaust odor orsmell. SUBARU recommends that you trya different brand of unleaded gasolinehaving lower sulfur to determine if theproblem is fuel related before returningyour vehicle to an authorized dealer forservice. The CHECK ENGINE warninglight/Malfunction indicator light may alsoilluminate. If this occurs, return to yourauthorized SUBARU dealer for diagnosis.If it is determined that the condition iscausedby the type of fuel used, repairsmay not be covered by your warranty.
!MMT
Some gasoline contains an octane-en-hancing additive called MMT (Methylcy-clopentadienyl Manganese Tricarbonyl). Ifyou use such fuels, your emission controlsystem performance may deteriorate andthe CHECK ENGINE warning light/Mal-function indicator light may illuminate. Ifthis happens, return to your authorizedSUBARU dealer for service. If it isdetermined that the condition is causedby the type of fuel used, repairs may notbe covered by your warranty.
!Gasoline for cleaner air
CAUTION
Do not let fuel spill on the exteriorsurfaces of the vehicle. Fuels con-taining alcohol may cause paintdamage, which is not covered underthe SUBARU Limited Warranty.

could make the pedals slippery anddriving dangerous.
While warming up the vehicle beforedriving, check that the accelerator pedal,brake pedal, and all other controls operatesmoothly.
Clear away ice and snow that hasaccumulated under the fenders to avoidmaking steering difficult. During severewinter driving, stop when and where it issafe to do so and check under the fendersperiodically.
!Parking in cold weather
WARNING
Snow can trap dangerous exhaustgases under your vehicle. Keepsnow clear of the exhaust pipe andfrom around your vehicle if you parkthe vehicle in snow with the enginerunning.
Do not use the parking brake whenparking for long periods in cold weathersince 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 toprevent the vehicle from moving.
When the vehicle is parked in snow orwhen it snows, raise the wiper blades offthe glass to prevent damage to them.
When the vehicle has been left parkedafter use on roads heavily covered withsnow, or has been left parked during asnowstorm, icing may develop on thebrake system, which could cause poorbraking action.Check for snow or icebuildup on the suspension, disc brakesand brake hoses underneath the vehicle.
If there is caked snow or ice, remove it,being careful not to damage the discbrakes and brake hoses and ABS har-ness.
!Refueling in cold weather
To help prevent moisture from forming inthe fuel system and the risk of its freezing,use of an antifreeze additive in the fueltank is recommended during cold weather.
Use only additives that are specificallydesigned for this purpose. When anantifreeze additive is used, its effect lastslonger if the tank is refilled whenever thefuel level reaches half empty.
If your SUBARU is not going to be usedfor an extended period, it is best to havethe fuel tank filled to capacity.
&Driving on snowy and icy
roads
WARNING
Do not use the cruise control onslippery roads such as snowy or icyroads. This may cause loss ofvehicle control.
CAUTION
Avoid prolonged continuous drivingin snowstorms. Snow will enter theengine’sintakesystemandmayhinder the airflow, which could re-sult in engine shutdown or evenbreakdown.
To prevent skidding and slipping, avoidsudden braking, abrupt acceleration, high-speed driving, and sharp turning whendriving on snowy or icy roads.
Always maintain ample distance betweenyour vehicle and the vehicle ahead of youto avoid the need for sudden braking.
To supplement the foot brake, use theengine brake effectively to control thevehicle speed. (Shift into a lower gearwhen necessary.)
Avoid shifting down abruptly. Such beha-
