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:
• Sport – Dry weather, on-road calibration. Only available in 4WD High
range. Performance-based tuning that provides a rear wheel drive feel
but with improved handling and acceleration over a two-wheel drive
vehicle. The Electronic Stability Control will set to allow more driver
control of the vehicle while maintaining safe handling controls. The
vehicle will lower (if equipped with Air Suspension) by 0.59 inches
(15 mm) in the SPORT mode.
• Snow – The Electronic Stability Control is set for additional stability in
inclement weather. Use on and off road on loose traction surfaces such
as snow.
• Auto – Fully automatic full-time four-wheel drive operation can be used
on and off road. Balances traction with steering feel to provide improved
handling and acceleration over two-wheel drive vehicles.
• Sand/Mud – Off-road calibration for use on low traction surfaces such as
mud, 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.
• 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. Activates the Hill Descent Control for
steep downhill control. Use for low speed obstacles such as large rocks,
deep ruts, etc.
Quadra-Lift™
• The Quadra-Lift™ air suspension
system provides full time load
leveling capability along with the
benefit of being able to adjust
vehicle height by the push of a
button. Quadra-Lift™ is available
with both Quadra-Trac II® and
Quadra-Drive II™.
• The system requires that the
engine be running for all changes.
When lowering the vehicle all of
the doors, including the liftgate,
must be closed.
