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). Your vehicle has a tamper resistant odometer. The digital odometer will read 999,999 if someone tries to turn it back. 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 you have driven since you last reset it. The trip odometer is accessed and reset through the Driver Information Center (DIC). See DIC Operation and Displays on page 219 for more information. Tachometer The tachometer shows your engine speed in revolutions per minute (rpm). 202
