Speedometer and Odometer Your speedometer lets you see your speed in both miles per hour (mph) and kilometers per hour (km/h). Your vehicle's odometer works together with the driver information center. You can set a Trip A and Trip B odometer. See "Trip Information" under DIC Operation and Displays on page 3-48. The odometer mileage can be checked without the vehicle running. Simply press the odometer/trip switch on the instrument panel cluster. If your vehicle ever needs a new odometer installed, the new one will be set to the correct mileage total of the old odometer. Safety Belt Reminders 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). This chime and light are repeated if the driver remains unbuckled and the vehicle is in motion. If the driver's safety belt is already buckled, neither the chime nor the light comes on. 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. This only occurs if the passenger airbag is enabled. See Passenger Sensing System on page 1-61 for more information. The passenger safety belt light, located on the instrument panel, comes on and stays on for several seconds and then flashes for several more. 3-32
