StabiliTrak® helps improve vehicle stability, particularly during emergency maneuvers. The StabiliTrak® control module compares your steering input with the vehicle’s actual response and, if necessary, makes small, individual brake and engine torque applications to enhance control and help you keep on track. StabiliTrak® automatically intervenes when it senses loss of lateral traction.



Key benefits include:

  • Helps the driver maintain control of the vehicle during certain low-traction driving conditions on loose, snowy, icy, wet or uneven road.
  • Helps the driver maintain control of the vehicle in emergency lane changes or avoidance maneuvers.
  • Helps the driver avoid collisions.
  • Helps automatically – If the system determines your vehicle is not responding properly, it will pulse the brakes or reduce engine power to help you stay on the path being steered.


Trailer Sway Control.

Working in conjunction with the StabiliTrak® electronic stability control system and Integrated Trailer Brake Controller (if equipped), the Trailer Sway Control feature on select GM vehicles senses trailer sway and automatically applies the vehicle and trailer brakes and reduces engine power, if necessary, to help you get back on track.


Integrated Trailer Brake Controller.
Completely integrated within the electrical system, antilock braking system and StabiliTrak® electronic stability control system, the Integrated Trailer Brake Controller (if equipped) allows your trailer’s brakes to operate simultaneously with the vehicle’s brakes. This is an option on select GM vehicles.

Service StabiliTrak®

Stop, turn off the engine for at least 15 seconds, then start the engine again. If this message still comes on, see your dealer for required service. The vehicle is safe to drive. If the message is on, you do not have the benefit of StabiliTrak®, so drive accordingly.
