yellowblue Speedometer/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 in kilometers (used in Canada). Your vehicle has a tamper-resistant odometer. If you see silver lines between the numbers, you'll know someone has probably tampered with it and the numbers may not be correct. 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 is what will be done. If it can't, then 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. Trip Odometer Your trip odometer tells how far you have driven since you last reset it. To set it to zero, press the reset button. Tachometer The tachometer displays the engine speed in thousands of revolutions per minute (rpm). NOTICE: Do not operate the engine with the tachometer in the red area, or engine damage may occur. 2-50
