The 2020 Terrain Denali premium suspension now adds an additional valve internal to the struts and shocks to deliver a more refined ride. This is in addition to the existing upgraded urethane spring isolators that reduce road noise over coarse roads.

Traction Select System

As driving conditions change, the standard Traction Select System allows you to make real-time adjustments for optimal performance. Available All-Wheel-Drive models feature the following modes:

  • FWD: Improves fuel economy1 in normal/everyday driving conditions by mechanically disconnecting the rear axle and eliminating the drag it causes
  • AWD: Actively sends power to the front and rear wheels to optimize traction on dry, wet or snow-/ice-covered roads
  • Off-Road: Adjusts AWD system, traction control and stability control to improve traction and driving dynamics on dirt, gravel or sand
  • Available Tow/Haul: Enhances trailering performance by providing Trailer Sway Control and automatically engages AWD to improve traction on boat ramps or gravel roads

Front-Wheel-Drive (FWD) models feature a Normal/Tour mode, Snow mode and available Tow/Haul mode, which lessens the chance of wheel slippage in low-traction driving conditions.
