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) or kilometers (used in Canada). Your vehicle has a tamper-resistant odometer. 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 cannot be, it will be 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. Dual Trip Odometers In addition to the standard odometer, the cluster can also display two separate trip odometers, designated by the letter A or B in the display window, as well as your vehicle's Engine Oil Life, which is designated by the word OIL in the display window. The display can be toggled between the odometer, the trip odometers, and engine oil life by quickly pressing and releasing the trip/reset button located to the right of the temperature gage. The display toggles once each time the trip/reset button is pressed for less than 1.5 seconds. The display toggles in the following sequence: Odometer - Trip Odometer A - Trip Odometer B - Engine Oil Life. If the engine oil life is left on the display, it will automatically toggle back to the odometer after about 15 seconds. Each of the two trip odometers can be used to keep track of different trip distances, such as the mileage of a long trip and the mileage driven on the current tank of fuel. The trip odometers will continue to keep track of miles (kilometers) driven even if they are not currently displayed. To reset the odometer to zero, press and hold the trip/reset button for at least 1.5 seconds, but less than three seconds. Only the trip odometer that is showing in the display will be reset. 3-36
