1. General Description
A: SPECIFICATION
Recommended oil:
Those with an API standard SM “Energy Conserving” logo.
ILSAC standard GF-4 ”Star burst mark” label on the container
CAUTION:
When replenishing oil, it does not matter if the oil to be added is a different brand from that in the en-
gine; however, use oil having the API standard and SAE viscosity No. designated by SUBARU.
NOTE:
If the vehicle is used in areas with very high temperatures or for other heavy duty applications, the following
viscosity oils must be used: API standard: SM or SL
SAE viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50

Basic Diagnostic Procedure
WIRING SYSTEM
•Each connector number shown in the wiring dia-
gram corresponds to that in the wiring harness. The
location of each connector in the actual vehicle is
determined by reading the first character of the
connector (for example, a “F” for F8, “i” for i16, etc. )
and the type of wiring harness. The first character
of each connector number corresponds to the area
or system of the vehicle.

Working Precautions
WIRING SYSTEM
2. Working Precautions
A: PRECAUTIONS WHEN WORKING
WITH THE PARTS MOUNTED ON
THE VEHICLE
1) When working under a vehicle which is jacked-
up, always be sure to use rigid rack.
2) The parking brake must always be applied dur-
ing working. Also, in automatic transmission vehi-
cles, keep the select lever set to the P (Parking)
range.
3) Be sure the workshop is properly ventilated
when running the engine. Further, be careful not to
touch the belt or fan while the engine is operating.
4) Be careful not to touch hot metal parts, especial-
ly the radiator and exhaust system immediately af-
ter the engine has been turned off.
B: PRECAUTIONS IN TROUBLE DI-
AGNOSIS AND REPAIR OF ELEC-
TRIC PARTS
1) The battery cable must be disconnected from
the battery’s (–) terminal, and the ignition switch
must be set to the OFF position, unless otherwise
required by the diagnostics.
2) Securely fasten the wiring harness with clamps
and slips so that the harness does not interfere with
the body end parts or edges and bolts or screws.
3) When installing parts, be careful not to catch
them on the wiring harness.
4) When disconnecting a connector, do not pull the
wires, but pull while holding the connector body.
5) Some connectors are provided with a lock. One
type of such a connector is disconnected by push-
ing the lock, and the other, by moving the lock up.
In either type the lock shape must be identified be-
fore attempting to disconnect the connector.
To connect, insert the connector until it snaps and
confirm that it is connected securely.
6) When checking continuity between connector
terminals, or measuring voltage across the terminal
and ground, always contact tester probe(s) on ter-
minals from the wiring connection side. If the probe
is too thick to gain access to the terminal, use “mini”
test leads.
To check water-proof connectors (which are not
measurable from the wiring side), contact test
probes on the terminal side. Be careful not to bend
or damage the terminals.
7) Sensors, relays, electrical unit, etc., are sensi-
tive to strong impacts.
Handle them with care so that they are not dropped
or mishandled.
