What is a car skidding light on dashboard of citroen xantia?

The car skidding light on the dashboard of a Citroen Xantia is the Electronic Stability Program (ESP) warning light. It indicates that the ESP system has been activated because the car is losing traction and is at risk of skidding. The ESP system uses sensors to detect when the car is skidding and applies the brakes to individual wheels to help the driver regain control. If the ESP warning light is illuminated, it is important to slow down and drive cautiously until the light turns off.
