Traction Select System With Tow/Haul Mode

The Traction Select System allows you to quickly switch between multiple traction configurations, including Off-Road mode and Tow/Haul mode, to optimize powertrain calibrations, traction control settings and stability control system calibrations for a variety of terrain and driving conditions. The system will retain the tow/haul setting configurations for up to 4 hours after the vehicle is turned off, eliminating the need to re-engage the system when returning from a brief stop on a long journey.
