StabiliTrak® Electronic Stability Control System with Traction Control, electronic trailer sway control and hill start assist helps keep you on the road and in control. The StabiliTrak control module compares your steering input with the vehicle's response and, if necessary, makes small, individual brake applications to keep you on track. The system automatically intervenes when it senses understeer (plowing), oversteer (fishtailing) or loss of lateral traction. In these situations, the system applies brake pressure and, if necessary, adjusts engine torque to help you get the vehicle back on track.
