Changing the oil and oil filter
Chang e the oil and oil filter ac c ord ing to the main tenanc e sc hed ule in
the “Warranty and Maintenanc e Booklet ”.
The eng ine oil and oil filter must b e c hang ed more freq uently than
listed in the maintenanc e sc hed ule when d riving on d usty road s,
when short trip s are freq uently mad e, or when d rivi ng in extremely
c old whether.
1. Warm up the eng ine b y letting the eng ine id le for ab out 10 minutes
to ease d raining the eng ine oil.
2. Park the vehic le on a level surfac e and stop the eng ine.
3. Remove the oil filler c ap .

4. Drain out the eng ine oil b y removing the d rain p l ug while the en-
g ine is still warm. The used oil should b e d rained into an ap p rop riate
c ontainer and d isp osed of p rop erly.
WARNING
Be careful not to burn yourself with hot engine oil.
5. Wip e the seating surfac e of the d rain p lug with a c lean c loth and
tig hten it sec urely with a new sealing washer after the oil has c om-
p letely d rained out.

12. Reinstall the c over und er the oil filter.
13. Pour the sp ec ified amount of eng ine oil throug h
the filler nec k.
Oil c ap ac ity: 4.2 US q t (4.0 liters, 3.5 Imp q t)
14. Start the eng ine and make sure that no oil leak s ap p ear around
the filter ’s rub b er seal.
15. Run the eng ine until it reac hes the normal op er ating temp erature.
Then stop the eng ine and wait a few minutes to allo w the oil d rain
b ac k. Chec k the oil level ag ain and if nec essary, a d d more eng ine oil.
Recommended grade and viscosity CAUTION
Use only engine oil with the recommended grade and viscosity.
Oil grade: API classification SJ or SH with the words “ENERGY
CONSERVING II ” (if you cannot obtain the oil with SJ
or SH grade, you may use SG grade oil.) or the new API certification mark (Starburst mark) dis-
played on the container.

Cooling system
WARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
CAUTION
The cooling system has been filled at the factory with a high
quality, corrosion-inhibiting, year-around coolant which providesprotection against freezing down to –33F ( –36 C). For adding,
use genuine SUBARU coolant or an equivalent: a mixture of 50%
soft water and 50% ethylene-glycol basis coolant. Use of improp-er coolants may result in corrosion in the cooling system. It is im-portant to maintain protection against freezing and corrosion,
even if freezing temperatures are not expected. Never mix differ-ent kinds of coolant. Do not splash the engine coolant over painted parts. The alco-
hol contained in the engine coolant may damage the paint sur-face.
Hose and connections
Your vehic le emp loys an elec tric c ooling fan whic h is thermostatic ally
c ontrolled to op erate when the eng ine c oolant reac h es a sp ec ific tem-
p erature.
If the rad iator c ooling fan d oes not op erate even w hen the eng ine
c oolant temp erature g aug e exc eed s the normal op erat ing rang e, the
c ooling fan c irc uit may b e d efec tive. Chec k the fus e and rep lac e it if
nec essary. If the fuse is not b lown, have the c ooli ng system c hec ked
b y your SUBARU d ealer.
If freq uent ad d ition of c oolant is nec essary, there may b e a leak in the
eng ine c ooling system. It is rec ommend ed that the c ooling system
and c onnec tions b e c hec ked for leaks, d amag e, or lo oseness.

Air cleaner element
WARNING
Do not operate the engine with the air cleaner element removed. The air cleaner element not only filters intake air but also stops
flames if the engine backfires. If the air cleaner element is not
installed when the engine backfires, you could be burned.
The air c leaner element func tions as a filter sc ree n. When the element is
p erforated or removed , eng ine wear will b e exc essiv e and eng ine life
shortened .
The air c leaner element is a visc ous typ e. It is un nec essary to c lean or
wash the element.
Replacing the air cleaner element
Rep lac e the air c leaner element ac c ord ing to the ma intenanc e sc hed -
ule in the “Warranty and Maintenanc e Booklet ”. Und er extremely
d usty c ond itions, rep lac e it more freq uently. It is rec ommend ed that
you always use g enuine SUBARU p arts.

Automatic transmission fluid
Checking the fluid level
The automatic transmission fluid exp and s larg ely as its temp erature
rises; the fluid level d iffers ac c ord ing to fluid t emp erature. Therefore,
there are two d ifferent sc ales for c hec king the lev el of hot fluid and
c old fluid on the d ip stic k.
Thoug h the fluid level c an b e c hec ked without warmi ng up the fluid
on the “COLD ” rang e, we rec ommend c hec king the fluid level when
the fluid is at op erating temp erature. n Checking the fluid level when the fluid is hot
Chec k the fluid level monthly.
1. Drive the vehic le several miles to raise the temp erature of the
transmission fluid up to normal op erating temp eratu re; 140 to 176F
(60 to 80 C) is normal.
2. Park the vehic le on a level surfac e and set the p arking b rake.
3. First shift the selec tor lever in eac h p osition. Then shift it in the “P ”
p osition, and run the eng ine at id ling sp eed .
