![]() It will stay on if there's a fault in your ESC system. This dash light will come on when the ESC system kicks on. It monitors your wheel speed and steering inputs and applies your brakes in the way necessary to prevent spinning or sliding off your vehicle. The whole job of stability control is to keep your vehicle heading in your intended direction. If your tires are not below the recommended pressure, you may have a faulty tire pressure sensor that needs to be replaced.Īnother component of your anti-lock braking system is electronic stability control (ESC). This light can alert you when you have a low tire due to a puncture or simply seasonal temperature changes. It's best to stop in a safe location and assess the condition of your tires. Some vehicles may show you exactly which tire is low in pressure, while others may not. This light signals that one of your tires is underinflated. Your tire pressure warning light is a yellow light with an exclamation point surrounded by a tire. A very common reason this light comes on is a faulty wheel speed sensor. An ABS system is intended to help enhance your braking performance on slippery roads by pulsing your brake pedal so that it doesn't lock up. This light will illuminate when there's a problem with your anti-lock braking system. It features a yellow or red-colored circle with the letters "ABS" in the middle. The Anti-lock Brake System (ABS) warning light is one of the most identifiable. Your car can overheat due to a number of issues, including a broken head gasket, stuck thermostat, broken water pump, leaky radiator, or a hole in your coolant hoses. It's best to pull over and turn off your vehicle so that it can cool down. This is a very serious problem that needs to be addressed before you continue to drive your vehicle. When this light comes on, it means that your engine is overheating. You'll notice this indicator light by a red thermometer. On some newer cars, the dashboard display will say "Service Engine Soon" or "Check Engine." You'll notice this light by a red or amber color that features an outline of an engine. This could be something as simple as a loose gas cap or as serious as an engine misfire. However, it's not overly specific about what the problem may be. This light is intended to warn you of engine-related issues. ![]() Probably the most common dash light that you'll have come on is the check engine light. With so many components, it's no surprise that many things can go wrong. In fact, the average car coming off of the production line has over two dozen computer modules that assist in running the vehicle and all of its included features. There's no denying the fact that modern vehicles are very complex machines.

It does, however, most likely mean that you have developed a small coolant leak, and it would be best to figure that out and fix it. Add coolant to the reservoir (as per manual instructions as to mix and type) and that will almost certainly fix the light. When you heat up the car, coolant expands and the overflow goes out the reservoir, and covers the sensor but the car doesn’t update the light until the next time you start it. When the car cools down the coolant contracts and gets sucked back into the radiator/cooling system, and the sensor goes dry and triggers the light. (From below the radiator cap, follow a black rubber hose to a plastic tank that has coolant in it). The sensor for the coolant level is in your overflow reservoir.
