StabiliTrak Electronic Stability Control System

---

Standard on all Avalanche models, the StabiliTrak Electronic Stability Control System improves vehicle stability, particularly during emergency maneuvers.

Here's how it works:

• The StabiliTrak control module compares your steering input with the truck's actual response and then, if necessary, makes small, individual brake applications to enhance control and keep the vehicle on track.
• StabiliTrak automatically intervenes when it senses loss of lateral traction (sideslip), understeer (plowing) or oversteer (fishtailing).
• In these situations, the system applies brake pressure and, if necessary, adjusts engine torque to help the driver get the vehicle back on track.
• Also included is Proactive Roll Avoidance, which reduces the tendency of the vehicle to roll over in a panic situation.
