SELEC-TERRAIN — IF EQUIPPED
S -T M S
ELEC ERRAIN ODE ELECTION
Selec-Terrain combines the capabilities of the
vehicle control 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 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).
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.
STARTING AND OPERATING
ROCK – Off-road calibration is only available

in 4WD LOW range. 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 AUTO, the Selec-Terrain system will
return to AUTO.
