Mine didn't come with one either. I bought mine from CarMax. They gave me an 800 number to call. It sounded like the number was to Toyota. They sent me a manual for free. I'll try to dig up the number.
I found 2 numbers. Try Toyota first. They didn't charge me. The number is 800-331-4331. I also have a number for Helms Publications 800-782-4356. I didn't have to use this one, so I'm not sure if they can help.
