yellowblue 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). Press the E/M (English/Metric) button on the left side of the instrument cluster to switch the display between miles and kilometers. Pressing this button will also cycle all other displays through English and metric units. 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 it must be. But if it can't, then it's 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, in either miles or kilometers, since you last reset it. Press the E/M (English/Metric) button on the left side of the instrument cluster to switch the display between miles and kilometers. The trip odometer is displayed by pressing the TRIP button. To reset it to zero, press TRIP to display the trip odometer, then hold the button for about three seconds until the display resets. Tachometer The tachometer displays the engine speed in revolutions per minute (rpm). NOTICE: Do not operate the engine with the tachometer in the red area. Engine damage may occur. Warning Lights, Gages and Indicators This part describes the warning lights and gages that may be on your vehicle. The pictures will help you locate them. Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to your warning lights and gages could also save you or others from injury. 2-57
