Maintenance and Care
Claims against the warranty resulting from lack of maintenance, as
opposed to defective materials o r authorized Toyota workmanship , will
not be honored.
Any auto repair shop using parts equivalent to your Toyota’s or iginal

The malfunction diagnosis connec tor is designed exclusively for con-
necting the specially designed de vice to perform on-board diagnosis.
Do not connect any devices other than the specially designed ma l-
function diagnosis devices for s ervicing. If any device other than the
malfunction diagnosis device is c onnected, it may affect the vehicle’s
electrical devices or lead to da mage such as battery depletion.
If you elect to perform maintenance yourself or have your vehic le serviced at
a location other than your Toyota dealer, Toyota requires that all fluids, parts
and materials must meet Toyota standards for durability and per formance as
described in this manual.
