SELEC-TERRAIN™
Selec-Terrain™ combines the capabilities of the vehicle control systems, along with
driver input, to provide the best performance for all terrains.
Rotate the mode control knob to select the following Selec-Terrain™ 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 suspension, the
level will change to Normal Ride Height (NRH).
Auto – Fully automatic full time four-wheel drive operation can be used on and off
road. Balances traction with seamless steering feel to provide improved handling and
acceleration over two-wheel drive vehicles. If equipped with air suspension, the level
will change to NRH.
Sand – Off road calibration for use on low traction surfaces such as sand or wet grass.
Driveline is maximized 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 level will change to
NRH.
Mud – Off road calibration for use on low traction surfaces such as mud. Driveline is
maximized 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 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. Activate the Hill
Descent Control for steep downhill control. 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.
