What do you do when the ESP malfunction light is on?

When the ESP (Electronic Stability Program) malfunction light is on, the first step is to check your vehicle's manual for specific guidance. It's advisable to safely pull over and inspect the vehicle for any obvious issues, such as low brake fluid or sensor damage. If no immediate problems are found, it’s best to take the car to a qualified mechanic for diagnostic testing, as driving with this light on can affect vehicle stability and safety. Ignoring the light could lead to more serious issues down the line.
