1. Make sure your mileage display is set on the odometer.
2. Turn off the car.

"When a legislature undertakes to proscribe the exercise of a citizen's constitutional rights it acts lawlessly and the citizen can take matters into his own hands and proceed on the basis that such a law is no law at all."

- Justice William O. Douglas

I would find another dealer. A decent one would have told you to check the manual for instructions rather than try to rip you off $25.
