Sit in the driver's seat. Put your seat belt on. With the key in the off position, press and hold in the odometer reset button. Turn the key one click (keep holding the odometer reset button in). Very shortly afterwards you will get a "RESET" (or similar) display. Release the odometer reset button. The display "RESET" will blink. While blinking press the odometer reset button again. That should do it.

normally these engines are ok. check the air filter, is it wet, if so replace it, keep airbox open and allow engine to dry out completey, reassembly vehicele with dry airfilter, and start engine, if engine runs, rev it up very high to blow out any water in engine. engine might be good still even though it runs very poorly, the vehicle will have to driven hard for at least 10 miles and the check engine light will have to be reset. if engine does not clear up and run smooth after 20 miles of hard driving it is probably bad. good luck.
