This all-new system allows the driver to choose from preset drive modes that have been tailored for different terrain or weather conditions. It adjusts Sierra’s transmission shift points, throttle mapping and StabiliTrak to optimize performance for the situation. The system also reacts with the Adaptive Ride Control in Sierra Denali to further enhance the driving experience and refine the ride. The available modes in the Traction Select system are:
  • Tour
  • Sport
  • Off-Road (available on 4WD models)
  • Snow (2WD models only)
  • Tow/Haul
