Speedometer Odometer/Trip Odometer The Liquid Crystal Display (LCD) odometer is a combination trip odometer and total odometer. The total odometer is normally displayed. To see the trip odometer, press and release the SELECT control on the upper right side of the speedometer. To zero out the trip odometer, press and release the RESET control on the upper left side of the speedometer while the trip odometer is displayed. If the trip odometer is displayed, press and release the SELECT control to return the display to the total odometer value. Tachometer (If equipped) The tachometer will show you the engine's speed measured in revolutions per minute (RPM). The tachometer may move slightly when the key is placed in the ACC or ON position, with the engine off. This is normal and does not affect the performance of the tachometer when the engine is running. 24
