Change automatic transmission fluid
only as necessary.

’03 Tacoma U (L/O 0209)
2952003 MY TACOMA (OM35800U)
Generally, it is necessary to change
automatic transmission fluid only if
your vehicle is driven under one of
the Special Operating Conditions listed
in your “Scheduled Maintenance
Guide” or “Owner ’s Manual Supple-
ment”. When changing the automatic
transmission fluid, use only “Toyota
Genuine ATF Type TIV” (ATF
JWS3309 or NWS6500) to aid in
assuring optimum transaxle perfor-
mance.
Notice: Using automatic transmis-
sion fluid other than “Toyota Genu-
ine ATF Type TIV” may cause dete-
rioration in shift quality, locking up
of your transmission accompanied
by vibration, and ultimately damage
the automatic transmission of your
vehicle.
Please contact your Toyota dealer for fur-
ther details.
