Warning Lights: What Do They Mean?

Auto Care Advice

Warning lights are lights on the instrument panel/dashboard of a vehicle that alert the driver when something is wrong. Depending on the light and the severity of the problem, you may or may not notice performance issues. Warning lights can be serious in nature, such as the Check Engine Light, or more benign, such as the parking brake light.

It is normal for the lights to illuminate briefly when the vehicle is started, but if they stay on or begin to flash, you should take the vehicle into a repair shop to get it checked out. You should never ignore a warning light. Some of them indicate serious problems with your vehicle that could render it unsafe to drive.

When the temperature light comes on, it means your engine is overheating. If this light comes on while you are driving, immediately turn off the A/C and any other nonessential systems that are running, including the radio. When safe to do so, pull over. DO NOT open the hood for at least 20 to 30 minutes. While waiting, call a tow truck and have the vehicle towed to a qualified repair shop for a complete cooling system inspection and diagnosis.
