What Is It?
Chevrolet’s Stability Control System — StabiliTrak — helps you stay on course by detecting the difference between the steering wheel angle and the direction the vehicle is actually turning. StabiliTrak “reads” the steering wheel position, the amount of sideways force in play, the speed of the vehicle and the vehicle’s response to steering wheel input. It then uses the brakes and, if necessary, adjusts engine torque to help you keep your vehicle on track. Antilock Brakes and Traction Control are integral to the GM StabiliTrak system.

Customer Benefit:
In low-traction conditions like ice, snow, gravel, wet pavement and uneven road surfaces, electronic stability control systems like StabiliTrak are proven to help reduce single-vehicle crashes.

What Is It?
Traction Control helps reduce wheel spin during acceleration if surfaces you’re driving on are slippery. Certain Traction Control systems combine the ABS speed sensors with the braking system and a Powertrain Control Module to help your vehicle regain traction.

Customer Benefit:
By selectively applying brake pressure to individual wheels, Traction Control helps reduce wheel spin on loose or slippery surfaces.

What Is It?
The Antilock Braking System (ABS) is designed to keep the vehicle’s wheels rotating as the brakes are applied to assist the driver in achieving a controlled stop. Sensors monitor how fast the wheels rotate and feed the data continuously to the ABS computer. The vehicle’s brakes slow each wheel as the brake pedal is applied. However, when ABS is activated due to road conditions, the system repeatedly releases and applies pressure to the brakes. The wheels can keep rolling, thus retaining steering ability and enhanced stability while providing a higher braking force on most surfaces than a locked wheel provides.

Customer Benefit:
ABS helps you maintain steering control by reducing wheel lockup during hard braking on most slippery surfaces.

What Is It?
Electronic Brake Force Distribution monitors the condition of the road, the weight of the car and the number of passengers, and then regulates the amount of brake force needed for each of the four wheels. This system ensures optimum braking force is applied simultaneously at both axles, for maximum stability under heavy braking.

Customer Benefit:
Electronic Brake Force Distribution ensures effective braking with short stopping distances.

What Is It?
Brake Assist provides full braking power when it senses emergency braking. In a panic braking situation, the vehicle operator typically applies force to the brake pedal at a very rapid rate, but not necessarily with a great enough force to decelerate the vehicle fast enough based on the force alone. A braking control system can apply an appropriate level of braking during such a panic braking event. When panic braking is detected, the Brake Assist system automatically develops maximum brake boost in order to mitigate a driver’s tendency to brake without enough force.

Customer Benefit:
Brake Assist senses the severity of a braking situation and applies additional braking pressure when needed.
