Maintenance requirements
■Repair and replacement
It is recommended that genuine Toyota parts be used for repairs to ensure
performance of each system. If non-Toyota parts are used in replacement or
if a repair shop other than a Toyota dealer performs repairs, confirm the war-
ranty coverage.
To e n s u r e s a f e a n d e c o n o m i c a l d r i ving, day-to-day care and regular
maintenance are essential. It is the owner’s responsibility to perform
regular checks. Toyota recommends the following maintenance:
■General maintenance
General maintenance should be performed on a daily basis.
This can be done by yourself or by a Toyota dealer.
■Scheduled maintenance
Scheduled maintenance should be performed at specified inter-
vals according to the maintenance schedule.
For details about maintenance items and schedules, refer to the
“Scheduled Maintenance Guide” or “Owner’s Manual Supplement”.
■Do-it-yourself maintenance
Yo u c a n p e r f o r m s o m e m a i n t e n a n c e p r o c e d u r e s b y y o u r s e l f .
Please be aware that do-it-yourself maintenance may affect war-
ranty coverage.
The use of Toyota repair manuals is recommended.
