The numbers may not be true. you have the If optional digital odometer, it will say ERROR if someone has tampered with it. You may wonder what happens if a carhas to have a new odometer installed. If possible, the new one has to be setto thesame reading the old one had. If it can't be, then it's set at zero, but a label on the driver's door must show the old reading and when the new one was installed. W M I N G LIGHTS This section describes the warning lights that are on your vehicle. The pictures will help you locate them.
