Electronic Stability Control (ESC) System

The ESC system constantly monitors the direction of travel relative to the driver's intended course, except when the vehicle is traveling in reverse, and aids in keeping the vehicle traveling along that course. This is accomplished by the ABS module and the HCU modulating brake fluid pressure to the affected brake caliper(s) and by the PCM modulating engine torque.

When the ESC system activates, any of the following can occur:

• A rumble or grinding sound may be heard, much like ABS
• A small deceleration or a reduction in the acceleration of the vehicle
• The stability/traction control indicator (sliding car icon) flashes
• If the driver's foot is on the brake pedal, a vibration may be felt in the brake pedal, much like ABS
