Cooling and dehumidifying in high humidity and low tempera- ture weather condition
Und er c ertain weather c ond itions (hig h relative hum id ity, low temp era-
tures, etc .) a small amount of water vap or emission from the air outlets
may b e notic ed . This c ond ition is normal and d oes n ot ind ic ate any
p rob lem with the air c ond itioning system. Air conditioner compressor shut-off when engine is heavily loaded
To imp rove ac c eleration and g as mileag e, the air c o nd itioner c om-
p ressor is d esig ned to temp orarily shut off d uring air c ond itioner op -
eration whenever the ac c elerator is fully d ep ressed suc h as d uring

Refrigerant for your climate control system
Your air c ond itioner uses ozone friend ly refrig eran t HFC134a. There-
fore, the method of ad d ing , c hang ing or c hec king th e refrig erant is
d ifferent from the method for CFC12 (freon). Consul t your SUBARU
d ealer for servic e. Rep airs need ed as a result of u sing the wrong
refrig erant are not c overed und er warranty.
Air filtration system (if equipped)
If your vehic le ’s air c ond itioning system is eq uip p ed with a op tion al air
filtration system, rep lac e the filter element ac c or d ing to the rep lac ement
sc hed ule shown b elow. This sc hed ule should b e follo wed to maintain the

Do not attempt to use a cigarette lighter in the accessory
power socket. Do not place any foreign objects, especially metal ones such
as coins or aluminum foil, into the accessory power socket. Thatcould cause a short circuit. Always put the cap on the accessorypower socket when they are not in use. Use only electrical appliances which are designed for 12V DC
and which consume less than 120W. Overloading the accessorypower socket can cause a short circuit. Do not use double adapt-ers or more than one electrical appliance. If the plug on your electric appliance is either too loose or too
tight for the accessory power socket, this can result in a poorcontact or cause the plug to get stuck. Only use plugs that fit
properly. Use of an electric appliance in the accessory power socket for
a long period of time while the engine is not running can causebattery discharge. Before driving your vehicle, make sure that the plug and the
cord on your electrical appliance will not interfere with your shift-ing gears and operating the accelerator and brake pedals. If theydo, do not use the electrical appliance while driving.

Fuel
CAUTION
Use of a fuel which is low in quality or use of an inappropriate fuel additive may cause engine damage.
Fuel requirements 2.5 Liter models
The 2.5 Liter eng ine is d esig ned to op erate using u nlead ed g asoline
with an oc tane rating of 87 AKI or hig her. 3.0 Liter models
The 3.0 Liter eng ine is d esig ned to op erate using p remium unlead ed
g asoline with an oc tane rating of 91 AKI or hig her. Reg ular unlead ed
g asoline with an oc tane rating of 87 AKI may b e use d if nec essary.
For op timum eng ine p erformanc e and d riveab ility, it is rec ommend ed
that you use p remium g rad e unlead ed g asoline. Fuel octane rating
This oc tane rating is the averag e of the Researc h O c tane and Motor
Oc tane numb ers and is c ommonly referred to as the A nti Knoc k Ind ex
(AKI).
Using a g asoline with a lower oc tane rating c an c au se p ersistent and
heavy knoc king , whic h c an d amag e the eng ine. Do not b e c onc erned
if your vehic le sometimes knoc ks lig htly when you d rive up a hill or
when you ac c elerate. See your d ealer or a q ualified servic e tec hni-
c ian if you use a fuel with the sp ec ified oc tane ra ting and your vehic le
knoc ks heavily or p ersistently. Unleaded gasoline
The nec k of the fuel filler p ip e is d esig ned to ac c ep t only an unlead ed
g asoline filler nozzle. Und er no c irc umstanc es shou ld lead ed g aso-
line b e used b ec ause it will d amag e the emission c o ntrol system and
may imp air d riveab ility and fuel ec onomy.

7-4In ad d ition, some g asoline sup p liers are now p rod uc
ing reformulated
g asolines, whic h are d esig ned to red uc e vehic le emi ssions. SUBARU
ap p roves the use of reformulated g asoline.
If you are not sure what the fuel c ontains, you sho uld ask your servic e
station op erators if their g asolines c ontain d eterg ents and oxyg enates
and if they have b een reformulated to red uc e vehic l e emissions.
As ad d itional g uid anc e, only use fuels suited for y our vehic le as ex-
p lained b elow. Fuel should b e unlead ed and have an oc tane rating n o lower than
that sp ec ified in this manual. Methanol (methyl or wood alc ohol) is sometimes mixe d with un-
lead ed g asoline. Methanol c an b e used in your vehic le ONLY if it
d oes not exc eed 5% of the fuel mixture AND if it is ac c omp anied b y
suffic ient q uantities of the p rop er c osolvents and c orrosion inhib itors
req uired to p revent d amag e to the fuel system. Do n ot use fuel c on-
taining methanol EXCEPT und er these c ond itions.
If und esirab le d riveab ility p rob lems are exp erienc e d and you sus-
p ec t they may b e fuel related , try a d ifferent b ran d of g asoline b efore
seeking servic e at your SUBARU d ealer. Fuel system d amag e or d riveab ility p rob lems whic h r esult from the
use of imp rop er fuel are not c overed und er the SUBA RU Limited War-
ranty.

Manual transmission
WARNING
Do not drive the vehicle with the clutch disengaged (i.e., when the clutch pedal is depressed) or with the shift lever in the neutralposition. Engine braking has no effect in either of these condi-tions and the risk of an accident is consequently increased.
CAUTION
Shift into reverse ONLY when the vehicle has completelystopped. It may cause damage to the transmission to try shiftinginto reverse when the vehicle is moving.
The manual transmission is a fully sync hromeshed 5- forward and 1-re-
verse sp eed transmission.
