I expect it's in the owner's manual. Do you have that? If you don't, it would probably be worth buying one, or else you'll be back here for other things that aren't obvious.
hi AccordCodger
thanks for your reply
in my owner's manual is written how to change this only for "without multi-information display"
i have "with multi-information display" :/
still don't know how to solve this problem...
Try calling Toyota corporate at 1-800-331-4331 and follow the prompts to speak to someone in customer service. They should be able to tell you how to do it. If they don't know off hand, they will find out and call you back.
