Speedometer and Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Your odometer shows how far your vehicle has been driven, in either miles (used in the United States) orkilometers (used in Canada). Tachometer Tamper Resistant Odometer Your Oldsmobile has a tamper resistant odometer. If you see silver lines between the numbers, you'll know that someone has probably tried to turn it back, so the numbers may not be true. -2 You may wonder what happens if your vehicle needs a new odometer installed. If the new one can be set to the mileage total of the old odometer, then that will be done. If it can't, then set at zero and a label must be put on it's the driver's door to show the old mileage reading when the new odometer was installed. The tachometer displays the engine speed in revolutions per minute (rpm). I NOTICE: Do not operate the engine with the tachometer in the red area,or engine damage may occur. 2-74
