Speedometer and Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers perhour (km/h). Your odometer shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). Your vehicle hasa tamper resistant odometer. If you see silver linesbetween 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 tothe 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. Trip Odometer The trip odometer can tell you how far you have driven sinceyou last reset it. To reset the trip odometer to zero, press the knob below it. 2-49
