1. Park the vehic le on a level surfac e and stop the eng ine.
2. Pull out the d ip stic k, wip e it c lean, and insert it ag ain.
3. Be sure the d ip stic k is c orrec tly inserted until it stop s with the
g rap hic symb ol
on its top ap p earing as shown in the illustra-

4. Pull out the d ip stic k ag ain and c hec k the oil lev el on it. If it is b elow
the lower level, ad d oil to b ring the level up to t he up p er level.
CAUTION
Use only engine oil with the recommended grade and viscosity.
If you c hec k the oil level just after stop p ing the eng ine, wait a few min-
utes for the oil to d rain b ac k into the oil p an b ef ore c hec king the level.
Just after d riving or while the eng ine is warm, the eng ine oil level
read ing may b e in a rang e b etween the up p er level a nd the notc h
mark. This is c aused b y thermal exp ansion of the en g ine oil.
To p revent overfilling the eng ine oil, d o not ad d a ny ad d itional oil
ab ove the up p er level when the eng ine is c old .

In c hoosing an oil, you want the p rop er q uality and
visc osity, as well
as one that will ad d to fuel ec onomy. The following tab le lists the rec -
ommend ed visc osities and ap p lic ab le temp eratures.
When ad d ing oil, d ifferent b rand s may b e used tog et her as long as
they are the same API c lassific ation and SAE visc os ity as those rec -
ommend ed b y SUBARU.
Eng ine oil visc osity (thic kness) affec ts fuel ec ono my. Oils of lower vis-
c osity p rovid e b etter fuel ec onomy. However, in hot weather, oil of
hig her visc osity is req uired to p rop erly lub ric ate the eng ine.

SAE viscosity numbr and applicable temperature
Recommended grade and viscosity under severe driving conditions
If the vehic le is used in d esert areas, in areas wi th very hig h temp era-
tures, or used for heavy-d uty ap p lic ations suc h as a towing a trailer,
use of oil with the following g rad e and visc osities is rec ommend ed .

eng ine is c ool.
2. If the level is c lose to or lower than the “LOW ” level mark, ad d
c oolant up to the “FULL ” level mark. If the reserve tank is emp ty, re-
move the rad iator c ap and refill as req uired .
