Gages can indicate when theremay be or is aproblem with one of your vehicle's functions. Often gages and warning lights work together to let you know when there's a problem with yourvehicle. When one of the warning lights comes on and stays on when you are driving, or when one of the gages shows there may be a problem, check the section that tells you what to do about it. Pleasefollow this manual's advice. Waiting to do repairs can be costly -- and even dangerous. So please get to know your warninglights and gages. They're abig help. Warning Lights, Gages and Indicators This part 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 come 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 whenyou start the engine just to let youknow they're working. If you are familiar with this section, you should not be alarmed when this happens. Safety Belt Reminder Light When the key is turned to RUN or START, a tone will come on for about eight seconds to remind people to fasten their safety belts, unless the driver's safety belt is already buckled. The safety belt light will also come on and stay on for about 20 seconds, then it will flash for about 55 seconds. If the driver's belt is alreadybuckled, neither the tone nor the light will come on.
