Trailer Sway Control (TSC)
The vehicle has a Trailer Sway Control (TSC) feature as part of the StabiliTrak system.
If TSC detects that the trailer is swaying, the vehicle's brakes are automatically applied.

When TSC is applying the brakes, the TCS/StabiliTrak indicator light flashes to notify the driver to reduce speed. If the trailer continues to sway, StabiliTrak will reduce engine torque to help slow the vehicle.
TSC will not function if StabiliTrak is turned off. See StabiliTrak® System for more information.
