Standard Autotrac

Drive confidently in almost all weather conditions with Autotrac.

  • When Autotrac is activated, a computer chip begins to monitor wheel slippage.
  • When slippage is detected, Autotrac automatically transfers torque from the rear wheels to the front wheels for enhanced traction.
  • As traction is improved and wheel slippage is no longer detected, the system returns to 2WD.

Available Locking Rear Differential

Automatic locking rear differential is designed to evenly distribute power to both rear wheels in less-than-ideal traction conditions. At lower speeds, the differential automatically senses wheel spin, locks the rear axle and transfers torque to the rear wheel with more traction, greatly helping your ability to handle slippery road conditions.

Standard StabiliTrak

StabiliTrak® helps your vehicle respond to your steering commands. During difficult driving conditions, sensors feed data to an onboard computer that adjusts engine speed, and brake pressure to any individual wheel to help keep you on track as seen in the animation above.

Standard Tow / Haul Mode

An innovative Tow/Haul mode gives automatic transmissions on selected models a dual-mode shift program that can hold gears longer to transfer more torque when it's needed. It helps put an end to hunting between gears when climbing hills.
