6) Tighten the engine oil drain plug after draining
engine oil.
Tightening torque:
44 N
⋅m (4.5 kgf-m, 32.5 ft-lb)
7) Install the service hole cover.
8) Fill engine oil through the filler pipe up to upper
point on level gauge. Make sure that the vehicle is
placed level when checking oil level. Use the en-
gine oil of proper quality and viscosity, selected in
accordance with the table in figure.
Recommended oil
API classification SL, SJ with the “Energy
Conserving” logo is printed, or SH (if you
cannot obtain the oil with SL, SJ or SH
grades, you may use SG, SF grades “ENER-
GY CONSERVING” oil.)
ACEA specification, A1, A2 or A3
CCMC specification, G4 or G5
New API certification mark (Star burst mark)
label is on the container.
Engine oil capacity:
Upper level
4.02 (4.2 US qt, 3.5 Imp qt)
Lower level
3.02 (3.2 US qt, 2.6 Imp qt)
 Non-turbo model Turbo model
The proper viscosity helps vehicle get good cold
and hot starting by reducing viscous friction and
thus increasing cranking speed.
CAUTION:
When replenishing oil, it does not matter if the
oil to be added is a different brand from that in
the engine; however, use oil having the API
classification and SAE viscosity No. designat-
ed by SUBARU.
NOTE:
If the vehicle is used in areas with very high tempera-
tures or for other heavy duty applications, the follow-
ing viscosity oils may be used: API classification: SL
or SJ or SH
SAE Viscosity No. : 30, 40, 10W-50, 20W-40, 20W-
50.
9) Close the engine oil filler cap.
10) Start the engine and warm it up for a time.
11) After the engine stops, recheck the oil level. If
necessary, add engine oil up to the upper level on
level gauge.

3 CHECK INDICATION OF DTC ON DISPLAY
1) Turn the ignition switch to OFF.
2) Connect the Subaru Select Monitor or the
OBD-II general scan tool to data link connec-
tor.
3) Turn the ignition switch to ON and the Sub-
aru Select Monitor or OBD-II general scan tool
switch to ON.
4) Read the DTC on the Subaru Select Moni-
tor or OBD-II general scan tool.Does the Subaru Select Moni-
tor or OBD-II general scan tool
indicate DTC?Record the DTC.
