Speedometer and Odometer Your speedometer lets you see your speed in either miles per hour (mph) or kilometers per hour (km/h). There is only one scale for mph and km/h. When you press the E/M (English/metric) button on the Driver Information Center (DIC), the cluster will calculate the proper speed and move the needle to the correct position. Either the MPH or the km/h telltale will illuminate, depending on which measurement you choose. To read the odometer with the ignition off, turn on the parking lamps. You may wonder what happens if your vehicle needs a new odometer installed. The mileage total of the new odometer will be set to the original miles (kilometers) of the old odometer. See your dealer if the odometer must be replaced in your vehicle. Tachometer The tachometer displays the engine speed in thousands of revolutions per minute (rpm). Fuel will shut off at about 6200 rpm (6500 rpm for Z06). If you continue to drive your vehicle at the fuel shut off rpm, you could damage your engine. Be sure to operate your vehicle below the fuel shut off rpm or reduce your rpm quickly when the fuel shuts off. Safety Belt Reminder Light When the key is turned to ON or START, a chime will come on for several seconds to remind people to fasten their safety belts, unless the driver's safety belt is already buckled. The safety belt light will also come on and stay on until the driver's belt is buckled. 3-34
