The trip odometer can tell you how far your vehicle has been driven since you last set the trip odometer to zero. Make sure the button is completely depressed to reset the trip odometer. To set the trip odometer on the standard cluster to zero, fully depress the button near the readout. The trip odometer on the digital cluster will appear in place of your regular odometer when you press down on the Trip button. To reset the trip odometer on the digital cluster, press down on the Reset button. To change back to the regular odometer, press down on the Trip button again. Tachometer The tachometer displays the engine speed in revolutions per minute (rpm). It is available only with the digital speedometer. NOTICE: Do not operate the engine with the tachometer in the red area, or engine damage may occur. Warning Lights, Gages and Indicators This section describes the warning lights and gages that may be on your vehicle. The pictures will help you locate them. Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to your warning lights and gages could also save you or others from injury. Warning lights go on when there may be or is a problem with one of your vehicle's functions. As you will see in the details on the next few pages, some warning lights come on briefly when you turn the ignition key just to let you know they're working. If you are familiar with this section, you should not be alarmed when this happens. 7-67
