NOTE
For models except STI, it is unneces-
sary to check the deflection of the drive
belt periodically because this engine is
equipped with an automatic belt ten-
sion adjuster. However, have the belt
replaced according to the maintenance
schedule in the "Warranty and Main-
tenance Booklet". Consult your
SUBARU dealer for replacement.
If the drive belt is loose, cracked or
worn, contact your SUBARU dealer.
