1996 Oldsmobile Aurora Owner's Manual - Page 117

Speedometer Odometer and Trip Odometer Your odometer shows how far your vehicle has been driven in either miles (used in the UnitedStates) or kilometers (used in Canada). Your trip odometer tells you howfar you have driven since you last reset it. Press the trip button located next to the trip odometer below the fuel gage. Your Aurora has a tamper resistant odometer. If you see silver lines between the numbers, you'll know someone has probably tampered withit and the numbers may not be true. You may wonder whathappens if your vehicle needs a new odometer installed. If the new one can beset to the mileage total of the old odometer, then it must be. But if it can't, then it's set at zero and label must be put on a the driver's door to show the old mileage reading when the new odometer was installed. Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h).
