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.

camper, the total cargo load of the truck
consists of the manufacturer ’s camper
weight figure, the weight of installed addi-
tional camper equipment not included in
the manufacturer ’s camper weight figure,
the weight of camper cargo, and the
weight of passengers in the camper.
The total cargo load should not exceed
the truck’s cargo weight rating and the
camper ’s center of gravity should fall with-
in the truck’s recommended center of
gravity zone when installed.
CAUTION
Be careful—overloading can cause
dangerous braking and handling prob-
lems, and can damage your vehicle
and its tires.
