Jeep Grand Cherokee 2014 Operating Manual page 224

Selec-Terrain™ consists of the following posi-
tions:
• 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 operat-
ing 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) if the
transfer case is in high range. The level will
change to Off-Road 1 if the transfer case is in
Low range.
• 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 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 sur-
faces. 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.
• 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™ sys-
tem will return to AUTO.
