2005 GMC Sierra 1500 Pickup Owner's Manual - Page 199

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). Tachometer Your tachometer displays the engine speed in revolutions per minute (rpm). See "Grade Braking" under Tow/Haul Mode on page 2-29 for more information. Notice: If you operate your vehicle with the tachometer above 6,000 rpm, your vehicle could be damaged. The repairs would not be covered by your warranty. Do not operate the engine with the tachometer above 6,000 rpm. Engine Hour Meter Display If equipped, the Driver Information Center (DIC) can also display the number of hours the engine has run. To display the hour meter, turn the ignition off, press and hold the reset button for at least four seconds. The hour meter will be displayed for up to 30 seconds, or until the ignition is turned on. See DIC Operation and Displays on page 3-51 for more information. 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. If your vehicle is not equipped with the passenger sensing system, this chime and light will be repeated if the driver remains unbuckled and the vehicle is in motion. Trip Odometer The trip odometer can tell you how far your vehicle has been driven since you last set the trip odometer to zero. Press the reset button, located on the instrument panel cluster next to the trip odometer display, to toggle between the trip odometer and the regular odometer. Holding the reset button for approximately one second while the trip odometer is displayed will reset it. To display the odometer reading with the ignition off, press the reset button. 3-33
