I haven't got the owners manual yet, (it wasn't in the glove box?!) I've ahd the oil changed and I can't get the dumb light to go off.. Any other lexus owners have any suggestions? Thanks so much...

Take it to Lexus and have the oil changed? You may need an OBDII error code reader to reset the fault.

disconnect the neg lead of your battery for 5 minutes

Did you get this answered? It is probably similar to my ES350. Turn the engine off. Take your foot off the brake pedal. After pushing and holding down the ODO reset push the engine start switch. Continue to hold the ODO button until it shows all zeros. Then it is reset. Good Luck

Yea Stang you are right.it will surely work for him.
