*Change automatic transmission fluid only as
necessary. 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 ªOwner's Manual Supplement / Maintenance
Scheduleº. When changing the automatic transmission
fluid, use only Toyota Genuine ATF Type T±IV (AT F
JWS3309 or NWS6500) to aid in assuring optimum
transmission performance.NOTICE
Using automatic transmission fluid other than
Toyota Genuine ATF Type T±IV may cause
deterioration in shift quality, locking up of your
transmission accompanied by vibration, and
ultimately damage the automatic transmission of
your vehicle.
