2010 Chevrolet Cobalt Owner's Manual - Page 166

Speedometer and Odometer The speedometer shows the speed in both kilometers per hour (km/h) and miles per hour (mph). The vehicle's odometer works together with the Driver Information Center (DIC). Trip A and Trip B can be set on the odometer. See "Trip Information" under DIC Operation and Displays on page 4‑38. The vehicle does not have to be running to check the odometer mileage. Simply open the driver's door and the mileage briefly displays. If the vehicle ever needs a new odometer installed, the new one will be set to the correct total mileage of the old odometer. Safety Belt Reminders Driver Safety Belt Reminder Light When the engine is started, a chime sounds for several seconds to remind a driver to fasten the safety belt, unless the driver safety belt is already buckled. The safety belt light comes on and stays on for several seconds, then flashes for several more. Tachometer The tachometer displays the engine speed in revolutions per minute (rpm). Notice: If the engine is operated with the tachometer in the shaded warning area, the vehicle could be damaged, and the damages would not be covered by the vehicle warranty. Do not operate the engine with the tachometer in the shaded warning area. This chime and light are repeated if the driver remains unbuckled and the vehicle is in motion. If the driver safety belt is already buckled, neither the chime nor the light comes on. Passenger Safety Belt Reminder Light For vehicles equipped with the passenger safety belt reminder light, several seconds after the engine is started, a chime sounds for several seconds to remind the front passenger to buckle their safety belt. The passenger safety belt light, located on the instrument panel, comes on and stays on for several seconds and then flashes for several more. 4-20
