Shift Positions
For additional information on the appropriate use of each
4WD system mode position, see the information below:
NEUTRAL
This range disengages the driveline from the powertrain. It
is to be used for flat towing behind another vehicle. Refer
to “Recreational Towing” in “Starting And Operating” for
further information.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the power transfer unit in the
NEUTRAL (N) position without first fully engaging
the parking brake. The NEUTRAL (N) position disen-
gages both the front and rear driveshafts from the
powertrain and will allow the vehicle to roll, even if
the transmission is in PARK. The parking brake
should always be applied when the driver is not in the
vehicle.
4WD LOW
This range is for low speed four-wheel drive. It provides an
additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose, slip-
pery road surfaces only. Do not exceed 25 mph (40 km/h).
NOTE:Refer to “Selec-Terrain – If Equipped” for further
information on the various positions and their intended
usages.
Shifting Procedures
Shifting Into 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition in the ON mode and the engine running, shift the
transmission into NEUTRAL, and push the “4WD LOW”
button once. The “4WD LOW” indicator light in the
instrument cluster will begin to flash and remain on solid
when the shift is complete.
280 STARTING AND OPERATING

NOTE:If shift conditions/interlocks are not met a mes-
sage will flash from the instrument cluster display with
instructions on how to complete the requested shift. Refer
to “Instrument Cluster Display” in “Getting To know Your
Instrument Panel” for further information.
Shifting Out Of 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition in the ON mode and the engine running, shift the
transmission into NEUTRAL, and push the “4WD LOW”
button once. The “4WD LOW” indicator light in the
instrument cluster will flash and go out when the shift is
complete.
NOTE:
• If shift conditions/interlocks are not met, a message will
flash from the instrument cluster display with instruc-
tions on how to complete the requested shift. Refer to
“Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
• Shifting into or out of 4WD LOW is possible with the
vehicle completely stopped; however, difficulty may
occur due to the mating clutch teeth not being properly
aligned. Several attempts may be required for clutch
teeth alignment and shift completion to occur. The
preferred method is with the vehicle rolling 0 to 3 mph
(0 to 5 km/h). If the vehicle is moving faster than 3 mph
(5 km/h), the 4WD system will not allow the shift.

STARTING AND OPERATING 283

Selec-Terrain offers the following modes:
•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 han-
dling and acceleration over two-wheel drive vehicles.
• 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.
• Sport — This mode alters the transmission’s automatic
shift schedule for sportier driving. Upshift speeds are
increased to make full use of available engine power.
NOTE: SPORT mode is not available when 4WD LOW is
selected. •
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. Traction based tuning with improved steer-
ability for use on high traction off-road surfaces. Use for
low speed obstacles such as large rocks, deep ruts, etc.
NOTE:
• Rock mode is only available on the vehicles equipped
with the Off-Road package.
• Activate the Hill Descent Control or Selec Speed Control
for steep downhill control. See “Electronic Brake Control
System” in “Safety” for further information.
Instrument Cluster Display Messages
When the appropriate conditions exist, a message will ap-
pear in the instrument cluster. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instrument Panel” for
further information.

STARTING AND OPERATING 285

STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function was developed to reduce fuel
consumption. The system will stop the engine automati-
cally during a vehicle stop if the required conditions are
met. Releasing the brake pedal or pressing the accelerator
pedal will automatically restart the engine.
Automatic Mode
The Stop/Start feature is enabled after every normal cus-
tomer engine start. At that time, the system will go into
STOP/START READY and if all other conditions are met,
can go into a STOP/START AUTOSTOP ACTIVE “Au-
tostop” mode.
To Activate The Autostop Mode, The Following Must
Occur:
•The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in the
instrument cluster display within the Stop/Start section.
Refer to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
• The vehicle must be completely stopped.
• The gear selector must be in a forward gear and the
brake pedal depressed. The engine will shut down, the tachometer will move to
the zero position and the Stop/Start telltale will illuminate
indicating you are in Autostop. Customer settings will be
maintained upon return to an engine running condition.
Possible Reasons The Engine Does Not Autostop
Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
Detailed information about the operation of the Stop/Start
system may be viewed in the instrument cluster display
Stop/Start Screen. In the following situations the engine
will not stop:
•
Driver ’s seat belt is not buckled.
• Driver ’s door is not closed.
• Battery temperature is too warm or cold.
• Battery charge is low.
• The vehicle is on a steep grade.
• Cabin heating or cooling is in process and an acceptable
