Speedometer and Odometer The speedometer shows the vehicle's speed in both miles per hour (mph) and kilometers per hour (km/h). The odometer shows how far the vehicle has been driven, in either miles (used in the United States) or kilometers (used in Canada). 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. Trip Odometer The trip odometer can show how far the vehicle has been driven since the trip odometer was last set 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 resets it. To display the odometer reading with the ignition off, press the reset button. 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 Tachometer The tachometer displays the engine speed in revolutions per minute (rpm). 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 1-90 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. 3-36
