etc., molded into the s idewall of each tire. 
Replace the tires if the treadwear indicators are showing on a  tire.
Rotate  the  tires  in  the  order

To  equalize  tire  wear  and  extend
tire  life,  Toyota  recommends  that
tire  rotation  is  carried  out  at  the
same interval as tire inspection.
Do  not  fail  to  initialize  the  tire
pressure  warning  system  after
tire rotation.
