2014-up model years

In addition to the Quadra-Lift air suspension, the Grand Cherokee's class-leading Selec-Terrain traction control system allows customers to choose the on- and off-road setting for optimum performance. This feature electronically coordinates up to 12 different powertrain, braking and suspension systems, including throttle control, transmission shift, transfer case, Hill-descent Control and Selec-Speed Control.

Modes:

The Selec-Terrain system has been refined for 2014 and offers five different driving conditions to achieve the best driving experience on all terrains:

• Auto: Automatically adapts to any on- or off-road situation

• Snow: Vehicle traction adjust for ultimate performance over snow-covered roads

• Sport - Available in 4HI, performance based tuning for RWD feel, reduces traction control

• Sand: Traction control and Quadra-Lift operate with sensitive response to wheel spin, and torque tuned for optimal performance in sand

• Mud: Traction control and Quadra-Lift operate with sensitive response to wheel spin, and torque tuned for optimal performance in mud

• Rock: Quadra-Lift air suspension system raises to maximum height of 11.3 inches, while the transfer case, differentials, and throttle coordinate to provide low-speed control

Sport Mode, previously found on the Selec-Terrain controller, is now engaged with the shift lever. Sport Mode provides enhanced on-road "fun-to-drive" capability.

Selec-Terrain, coupled with the Quadra-Lift air suspension, offers drivers an adjustable suspension span that delivers Trail Rated performance.
