Speedometer and Odometer The speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). The 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 by pressing the trip information stem. See "Odometer" under DIC Operation and Displays on page 3-38 for more information. If the cluster is replaced the new one will automatically detect and update the vehicle's accumulated mileage. Trip Odometer Your vehicle has a trip odometer that can tell you how far your vehicle has been driven since you last set the trip odometer to zero. See "Trip Odometer" under DIC Operation and Displays on page 3-38 for more information. Tachometer The tachometer displays the engine speed in revolutions per minute (rpm). Notice: If you operate the engine with the tachometer in the shaded warning area, your vehicle could be damaged, and the damages would not be covered by your warranty. Do not operate the engine with the tachometer in the shaded warning area. 3-25
