Maintenance and service/Spark plugs
Spark plugs
It may be difficult to replace the spark
plugs. It is recommended that you have
the spark plugs replaced by your
SUBARU dealer.
The spark plugs should be replaced
according to the maintenance schedule
in the“Warranty and Maintenance Book-
let”.
&Recommended spark plugs
Refer to“Electrical system”F12-9.
Drive belts
It is unnecessary to check the deflection of
the drive belt periodically because your
engine is equipped with an automatic belt
tension adjuster. However, replacement of
the belt should be done according to the
maintenance schedule in the“Warranty
and Maintenance Booklet”. Consult your
SUBARU dealer for replacement.
If the belt is loose, cracked or worn,
contact your SUBARU dealer.
Manual transmission oil
It is unnecessary to check the manual
transmission oil level. However, if neces-
sary, consult your SUBARU dealer for
inspection.
&Recommended grade and
viscosity
Each oil manufacturer has its own base
oils and additives. Never use different
brands together. For details, refer to
“Manual transmission, front differential
and rear differential gear oil”F12-7.

*1: This torque is equivalent to applying approximately 88 to 110 lbf (40 to 50 kgf) at the end of the wheel nut wrench. If you have tightened the wheel
nuts by yourself, have the tightening torque checked at the nearest automotive service facility as soon as possible. For the wheel nut tightening
procedure, refer to“Changing a flat tire”F9-5.
