1994 Buick LeSabre Owner's Manual - Page 108

The Instrument Panel:Your Information System 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 U.S.) or kilometers (used in Canada). Your Buick has a "tamper-resistant odometer." If you can see very noticeable bright silver lines between the numbers, probably someone has tried to turn it back. The numbers may not be accurate. You may wonder what happens if a car has to have a new odometer installed. The new one should be set to the same reading as the old one. If this is not possible, then it's set at zero, and a label on the driver's door must show the old reading and when the new one was installed. Your instrument panel is designed to let you know at a glance how your car is running. You'll know howfast you're going, how much fuel you're using, and many other things you'll need to know to drive safely and economically. 106
