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 operating
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 acceleration
over two-wheel drive vehicles. If equipped with
air suspension, the level will change to Normal
Ride Height (NRH) unless in the Off-Road 1
(OR1) or Off-Road 2 (OR2) position, the height of
OR1 or OR2 will be maintained.
SAND – Off-road calibration for use on low trac-
tion surfaces such as sand or wet grass. Drive-
line 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 trac-
tion surfaces such as mud. 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 manage-
ment of throttle and wheel spin. If equipped with
air suspension, the level will change to OR1.
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 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
out of 4WD LOW, the Selec-Terrain system will
return to AUTO.

ESSAGES
When the appropriate conditions exist, a message
will appear in the instrument cluster Ú page 73.
POWER STEERING
The electric power steering system will provide
increased vehicle response and ease of
maneuverability. The power steering system
adapts to different driving conditions and adjusts
accordingly.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.
Alternate electric power steering efforts can be
selected through the Uconnect System
Ú page 152.
