SELEC-TERRAIN — IF EQUIPPED
Selec-Terrain Mode Selection
Selec-Terrain combines the capabilities of the vehicle con- trol systems, along with driver input, to provide the best performance for all terrains.
Selec-Terrain Switch
Selec-Terrain consists of the following positions:
Snow – Tuning set for additional stability in inclement weather. Use on and off road on loose traction surfaces such as snow. When in Snow mode (depending on certain operating conditions), the transmission may use second gear (rather than first gear) during launches, to
minimize wheel slippage. If equipped with air suspen- sion, the default ride height for Snow is Normal Ride Height (NRH).
Auto – Fully automatic full time four-wheel drive op- eration can be used on and off road. Balances traction with seamless steering feel to provide improved han- dling and acceleration over two-wheel drive vehicles. If equipped with air suspension, the level will change to Normal Ride Height (NRH).

Sand – Off road calibration for use on low traction
surfaces such as sand or wet grass. Driveline is maxi- mized for traction. Some binding may be felt on less forgiving surfaces. The electronic brake controls are set to limit traction control management of throttle and wheel spin. If equipped with air suspension, the default ride height for Sand is Normal Ride Height (NRH).
Mud – Off road calibration for use on low traction surfaces such as mud. Driveline is maximized for trac- tion. Some binding may be felt on less forgiving sur- faces. The electronic brake controls are set to limit traction control management of throttle and wheel spin. If equipped with air suspension, the level will change to Off Road 1.
Rock – Off road calibration only available in 4WD Low range. The vehicle is raised (if equipped with Air Suspension) for improved ground clearance. Traction based tuning with improved steer-ability for use on high traction off-road surfaces. Use for low speed obstacles such as large rocks, deep ruts, etc. If equipped with air suspension, the vehicle level will change to Off-Road 2. If the Selec-Terrain switch is in ROCK mode, and the transfer case is switched from 4WD Low to 4WD High, the Selec-Terrain system will return to AUTO.
NOTE: Activate the Hill Descent Control or Selec Speed Control for steep downhill control. See “Electronic Brake Control System” in this section for further information.
When the appropriate conditions exist, a message will appear in the instrument cluster. Refer to “Instrument Cluster Display” in “Getting To Know Your Instrument Panel” for further information.
