to satisfy the following grade and
viscosity.
Oil grade: API grade SL “Energy −Conserving” or
ILSAC multigrade engine oil Recommended oil viscosity:
SAE 5W −30
Outside temperature
Please contact your Toyota dealer for fur-
ther details.

AUTOMATIC TRANSMISSION
Fluid capacity (drain and refill), L (qt.,
Imp. qt.): Up to 2.0 (2.1, 1.8)
Fluid type: Toyota Genuine ATF Type T −IV
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
“Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”. When
changing the automatic transmission fluid,
use only “Toyota Genuine ATF Type T
−IV”
(ATF JWS3309 or NWS6500) to aid in
assuring optimum transmission perfor-
mance.
Notice: Using automatic transmission
fluid other than “Toyota Genuine ATF
Type TIV” may cause deterioration in
shift quality, locking up of your trans-
mission accompanied by vibration, and
ultimately damage the automatic trans-
mission of your vehicle.
Please contact your Toyota dealer for fur-
ther details.
