I just did this a week ago and as you I don't have a manual. Ok on the passanger side of the driver open the door. Their is a fuse box on the side of the dash. Open that up and their is a red reset button. Now turn on your vehicle and press the reset button until the low tire indicator go off.
That should do it. I haven't had a problem since then.
