If the temperature warning light goes on, what should you do?

Stop as soon as you can at a safe place and shut the engine off
Open the radiator cap to check the water level
Keep driving to the nearest mechanic
Keep driving because it is a warning and not an indicator of a real problem

Stop as soon as you can at a safe place and shut the engine off. It is important to address the issue causing the temperature warning light to come on before it leads to serious damage to your engine. You should check the coolant level, radiator, and other possible causes of overheating before continuing to drive the vehicle.
