Antilock Brake System With Electronic Stability Control (ESC)

ELECTRONIC STABILITY CONTROL

Electronic Stability Control (ESC), which includes Hydraulic Brake Assist, Traction Control, Electronic Roll Mitigation, and Brake Lock Differentials is standard on all vehicles. ESC aids the driver in maintaining vehicle directional stability. ESC will do whatever can be done, within the limits of available traction, to keep the car on course.

ESC uses the ABS with Traction Control along with the following components to operate:

- Dynamics (ESC) Sensor
- Steering Angle Sensor (SAS)

The Dynamics Sensor that is mounted under the center console, which is near the center of gravity of the car for effective sensing Description and Operation. The Steering Angle Sensor is located in the steering column Description and Operation.

On this vehicle, ESC has three modes: Full-On, Partial and Full-Off. The ESC default mode is Full-On with every key-on. Pressing the ESC Off switch button in the center stack once activates the Partial mode. In Partial mode, Traction Control is deactivated and ESC operates at a higher threshold, therefore, it will not come on as aggressively as in the Full-On mode. Pressing and holding the ESC Off switch button for five seconds or longer turns the system completely off. This condition is confirmed by a single warning chime and a text message in the odometer display "ESC FULL OFF." The system can be returned to "normal" Full-On mode by briefly pressing and releasing the ESC Off switch.

HYDRAULIC BRAKE ASSIST

Brake Assist is programmed into the ESC system. Brake assist helps the driver overcome the tendency to not apply the brakes hard enough or quick enough to achieve the minimum stopping distance during a panic stop. During this situation, the ESC system instantly applies the maximum available pressure to the brakes and the vehicle stops as quickly as available traction will allow.
