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). The odometer mileage can be checked without the vehicle running. Simply press the trip odometer button. 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 The trip odometer can tell you how far your vehicle has been driven since you last set the trip odometer to zero. To view the trip odometer, press the button near the readout. To reset the trip odometer, hold the button until it clears. Tachometer (If Equipped) The tachometer displays the engine speed in revolutions per minute (rpm). Each tachometer has a different limit depending on the powertrain in your vehicle. The tachometer has three areas: normal operating range, red warning range and red danger range. The normal operating range shows your engine speed during normal driving conditions. For example, when the needle points to 2, it means the engine is running at 2,000 revolutions per minute (rpm). The tachometer needle will vary all the time that the engine is running. The shaded red warning range tells you that your engine speed is reaching its upper limits. Don't drive very long with the tachometer in the red warning range. If you have a manual transmission, shift to a higher gear as soon as possible. If you have an automatic transmission, lift your foot off the accelerator pedal. The solid red danger range tells you that your engine speed is at its upper limits. You should immediately shift to a higher gear, or lift your foot off the accelerator pedal. 2-54
