Quadra-lift is a vehicle air suspension system equipped in some Jeep Grand Cherokees. It is a technology that allows you to adjust your vehicle’s height by just the push of a button! Normal Ride Height (NRH) is the standard suspension height, for normal driving.

Click the “up” button to raise your Jeep Grand Cherokee for off-road ground clearance. Clicking “up” on your Jeep Grand Cherokee’s Quadra-lift will raise your vehicle to “sand/mud” or “rock.”

By clicking the “down” button, you will lower your vehicle for open-road driving to be more aerodynamic.

Finally, by pressing the “park” button, your vehicle will be lowered for ease of entry, exit, and cargo loading.

2012 Jeep Grand Cherokee: Selec-Terrain

Selec-Terrain is a system that gives you the ability to control and fine-tune your 4WD capabilities to suit the terrain and condition in which you are driving. It combines driver input as well as the vehicle control system capabilities to aid your vehicle in providing the optimal handling and driving performance in all types of terrains.

Selec-Terrain consists of the following positions:

Auto

• Standard driving mode for normal hard-surfaced roads
• Provides limited over/understeer
• Provides improved acceleration and handling compared to 2WD vehicles
• Combines best traction with a seamless steering feel

Sport

• Dry weather, on-road setting
• Provides improved acceleration and handling compared to 2WD vehicles
• Only available in 4WD high range
• Provides performance based fine tuning to provide rear wheel drive feel
• Electronic Stability Control (ESC) will set to provide you with more control of the vehicle while upholding safe handling
• Your vehicle will lower itself (if equipped with air-suspension) by 0.59 inches, or 15 mm

Snow

• Will provide confidence and stability for cold weather and snowy conditions
• Helps prevent spinouts or fishtailing caused by oversterring in slippery or snowy surfaces
• Minimize oversteer with more allowable understeer at lower speeds
• Driver may experience high friction noise or vibration that is required for improved traction

Sand/Mud

• This is an off-road setting for improved traction
• Electronic brake controls are optimized for low traction which prevents throttle management issues that are sometimes experienced in off-roading terrains
• Some harshness may be experienced or felt
• Driveline is optimized for traction

Rock

• Off-road calibration setting that is only available in 4WD low range
• Your vehicle will be raised (if equipped with air suspension) for higher ground clearance
• Used for high traction off-road surfaces
• Improved steer-ability
• Activates the “hill descent control” for steep down hill control
