What does this warning light mean?

What it means: A misfire bad enough to send unburned fuel into the exhaust, which can overheat and destroy the catalytic converter.

What to do: Ease off the gas and get off the road when it’s safe. Don’t keep driving it normally until the misfire is diagnosed.

What it means: The engine computer stored a trouble code. It can be anything from a loose gas cap to a failing sensor.

What to do: If the car drives normally, it’s usually OK short-term. Get the code read soon. Stop if it also runs rough, overheats or shows low oil pressure.

What it means: Oil pressure may be low while the engine is running. It is not a low-oil-level gauge.

What to do: Pull over safely, stop the engine and call a dealer or repair shop; running the engine with this light on can seriously damage it. Check the oil level on the dipstick, since the light itself doesn’t measure it.

What it means: The engine is running too hot, most often from low coolant, a stuck thermostat, a cooling fan that isn’t running or a bad belt or water pump.

What to do: Pull over, turn off the A/C, and shut the engine off if you see steam or the gauge is in the red. Never open the radiator cap hot.

What it means: The charging system isn’t keeping up: often the alternator, a loose or broken belt, or bad battery cables.

What to do: Turn off everything you don’t need and drive straight to a shop, or pull over safely. The car can stall with little warning.

What it means: Usually the parking brake isn’t fully released or the brake fluid is low.

What to do: Release the parking brake fully. If it stays on, treat it as a brake problem: check the fluid and have the brakes inspected before driving on.

What it means: The anti-lock system is switched off. Regular brakes usually still work, but wheels can lock in a hard stop.

What to do: Drive carefully to a shop, leaving extra stopping distance. If the red brake light is on too, stop driving.

What it means: The airbag or seat-belt pretensioner system found a fault. It should go out a few seconds after you start the car.

What to do: The car still drives, but the airbags may not work properly in a crash. Have the system checked right away if the light stays on, flashes, or never lights at startup.

What it means: Solid: one or more tires is well below the recommended pressure. Flashing for a minute then solid: the monitoring system has a fault.

What to do: Check all four tires with a gauge and fill to the pressure on the driver’s door-jamb sticker.

What it means: The emissions system found a fuel-vapor leak, most likely a loose or worn gas cap.

What to do: Tighten the cap until it clicks, or replace it if the seal is cracked. The light can take a few days of driving to go off.
