1. Understanding the ESP System in Your Mercedes-Benz

Electronic Stability Program (ESP), also known as Electronic Stability Control (ESC) in some regions, is a crucial safety system in your Mercedes-Benz. It is designed to prevent skidding and loss of control, particularly in challenging driving conditions. According to the National Highway Traffic Safety Administration (NHTSA), ESP systems reduce single-vehicle crashes by as much as 35%.

The ESP system works by constantly monitoring several factors, including:

Steering angle
Wheel speed
Yaw rate (the car’s rotation)
Lateral acceleration

Based on this data, the ESP system determines the intended direction of the vehicle. If it detects a discrepancy between the driver’s intended direction and the actual movement of the car, it intervenes by selectively applying brakes to individual wheels and adjusting engine power to help the driver regain control.
