Speedometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Trip Odometer Tamper-Resistant Odometer Your odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). Your Oldsmobile has a tamper-resistant odometer. If you see silverlines between the numbers, you'll know that someone has probably tried to turn it back, so the numbers may not be true. 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 it must be. But if it can't, then it's set at zero and a label must be put on the driver's door to show the old mileage reading when the new odometer was installed. The trip odometer can tell you how far you have driven since you last reset it. To reset the trip odometerto zero, press the knob to the right of the gage. 2-58
