Speedometer and Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Your odometer is located in your message center, and shows how far your vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). When information messages need to be shown in the message center, they will be shown in place of the odometer. To display the odometer after a message(s) is shown, clear each message by pressing the trip/reset button located to the right of the speedometer. See Message Center on page 3-39 for more information. 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 can't, 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. If the mileage is unknown, the label should then indicate "previous mileage unknown". Trip Odometer Your trip odometer shows how far your vehicle has been driven since the trip odometer was last reset. To reset the trip odometer to zero, press and hold the trip/reset button for about two seconds. Tachometer The tachometer is located on the instrument panel and displays the engine speed in revolutions per minute (rpm). 3-27
