This vehicle uses the Continental MK25E electronic brake control system. The system includes ABS (Anti-lock Brake System), EVBP (Electronic Variable Brake Proportioning), TCS (Traction Control System), BAS (Brake Assist System) and ESP (Electronic Stability Program). These system work together to enhance vehicle stability and control in various driving conditions and are commonly referred to as ESP. ESP is standard on this vehicle.

This electronic brake control system uses the following components to operate:

1. Integrated Control Unit (ICU) - Hydraulic Control Unit (HCU) (2) and Antilock Brake Module (ABM) (1)
2. Wheel Speed Sensors (WSS) - Four sensors (one sensor at each wheel)
3. Dynamics Sensor - The Dynamics Sensor includes the Yaw Rate Sensor and the lateral Acceleration Sensor.
4. Steering Angle Sensor (SAS) - The steering angle sensor is located in the Steering Column Control Module (SCCM) mounted on the steering column.
5. Brake Pressure Sensor - The brake pressure sensor is located in the HCU and is not serviceable separate from the HCU.
