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 or kilometers. Your vehicle has a tamper resistant odometer. 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 cannot, then it is 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. Safety Belt Reminder Light When the key is turned to RUN or START, a chime will be provided for several seconds to remind people to buckle their safety belts. The driver safety belt light will also be provided and stay on for several seconds, then it will flash for several more. You should buckle your seat belt. This chime and light will be repeated if the driver remains unbuckled and the vehicle is in motion. Trip Odometer A trip odometer can tell you how far you have driven since you last set it to zero. See Driver Information Center (DIC) on page 3-50 for information on resetting the trip odometer. If the driver's belt is buckled, neither the chime nor the light will be provided. Tachometer The tachometer tells you how fast the engine is running. It displays engine speed in thousands of revolutions per minute (rpm). 3-35
