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). The odometer mileage can be checked without the vehicle running. Simply press the trip stem located on the instrument panel cluster. You may wonder what happens if your vehicle needs a new odometer installed. The new one will be set to the correct mileage total of the old odometer. The odometer mileage can be checked without the vehicle running. Simply press the trip stem on the instrument panel cluster. If your vehicle ever needs a new odometer installed, the new one will be set to the correct mileage total of the old odometer. Tachometer The tachometer displays the engine speed in revolutions per minute (rpm). Trip Odometer The trip odometer can tell you how far your vehicle has been driven since you last set the trip odometer to zero. Your vehicle's odometer works together with the Driver Information Center (DIC). You can set a Trip A and Trip B odometer. See "Trip Information" under DIC Operation and Displays on page 3-51. 3-33
