STARTING AND OPERATING 139
Selec-Terrain consists of the following
positions:
ROCK – Off-road calibration is only available
in 4WD LOW. The vehicle is raised (if
equipped with air suspension) for improved
ground clearance. Traction-based tuning with
improved steerability for use on high traction
off-road surfaces. Use for low speed obsta-
cles 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 HI, the Selec-Terrain system will
return to AUTO.
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 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 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 OR1.
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 oper-
ating conditions), the transmission may use
SECOND gear (rather than FIRST gear) during
launches, to minimize wheel slippage. If
equipped with air suspension, the default
ride height for SNOW is 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 accelera-
tion over two-wheel drive vehicles. If
equipped with air suspension, the level will
change to Normal Ride Height (NRH).
SPORT – This mode is only available in 4WD
HI, and alters the transmission's automatic
shift schedule for sportier driving. Upshift
speeds are increased to make full use of
available engine power. Suspension settings
are optimized and steering assist is modified
to provide better handling performance.

QUADRA-LIFT — IF EQUIPPED
DESCRIPTION
The Quadra-Lift air suspension system provides
full time load leveling capability along with the
benefit of vehicle height adjustment by a toggle
switch. The vehicle will automatically raise and
lower the ride height to adapt to the appropriate
driving conditions. At higher speeds, the vehicle
will lower to an aerodynamic ride height and
when operating in off-road modes, the vehicle
will raise the ride height accordingly. The
buttons near the terrain switch in the center
console area can be used to set preferred ride
height to match the appropriate conditions.
