Ignition Park Interlock
This vehicle is equipped with an Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF mode. This helps the
driver avoid inadvertently leaving the vehicle without
placing the transmission in PARK. This system also locks
the transmission in PARK whenever the ignition is in the
OFF mode.
NOTE:The transmission is NOT locked in PARK when the
ignition is in the ACC mode (even though the engine will
be off). Ensure that the transmission is in PARK, and the
ignition is OFF(not in ACC mode) before exiting the
vehicle.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift the
transmission out of PARK, the engine must be running and
the brake pedal must be pressed. The brake pedal must
also be pressed to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or moving at low
speeds.
Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve the vehicle’s
overall fuel economy during normal driving conditions.
Push the “eco” button in the center stack of the instrument
panel to activate or disable ECO mode. A light on the
button indicates when ECO mode is disabled.

272 STARTING AND OPERATING
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.
NOTE:On vehicles equipped with the electronically
shifted transfer case, ensure that the transfer case is in
AWD AUTO or LOW RANGE position on the AWD
Control Switch. Ensure that the NEUTRAL position light is
NOT illuminated.
When exiting the vehicle, always:
• Apply the parking brake.
• Shift the transmission into PARK.
• Turn the ignition OFF.
• Remove the key fob from the vehicle.WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle
movement and possible injury or damage.
• Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the
transmission gear selector out of PARK with the
brake pedal released. Make sure the transmission is
in PARK before exiting the vehicle.
• The transmission may not engage PARK if the ve-
hicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and verify
that the transmission gear position indicator solidly
indicates PARK (P) without blinking. Ensure that the
vehicle is completely stopped, and the PARK posi-
tion is properly indicated, before exiting the vehicle.
• It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the

STARTING AND OPERATING 275
When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the AutoStick shift control
(refer to AutoStick in this section for further information) to
select a lower gear. Under these conditions, using a lower
gear will improve performance and extend transmission
life by reducing excessive shifting and heat buildup.
During cold temperatures, transmission operation may be
modified depending on engine and transmission tempera-
ture as well as vehicle speed. This feature improves warm
up time of the engine and transmission to achieve maxi-
mum efficiency. Engagement of the torque converter clutch
is inhibited until the transmission fluid is warm. Normal
operation will resume once the transmission temperature
has risen to a suitable level.
Manual (M)
The MANUAL (M, +/-) position (beside the DRIVE posi-
tion) enables full manual control of transmission shifting
(also known as AutoStick mode; refer to “AutoStick” in this
section for further information). Toggling the gear selector
forward (-) or rearward (+) while in the MANUAL(AutoStick) position will manually select the transmission
gear, and will display the current gear in the instrument
cluster as 1, 2, 3, etc.
Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the engine
may stall. In some situations, the transmission may not
re-engage if the engine is turned off and restarted. The
Malfunction Indicator Light (MIL) may be illuminated. A
message in the instrument cluster will inform the driver of
the more serious conditions, and indicate what actions may
be necessary.
In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
NOTE:
In cases where the instrument cluster message
indicates the transmission may not re-engage after engine
shutdown, perform this procedure only in a desired loca-
tion (preferably, at an authorized dealer).
278 STARTING AND OPERATING
This electronically shifted transfer case is designed to be
driven in the AWD AUTO position for normal street and
highway conditions on dry hard surfaced roads.
For variable driving conditions, the AWD AUTO mode can
be used. In this mode, the front axle is engaged, but the
vehicle’s power is sent to the rear wheels. All-wheel drive
will be automatically engaged when the vehicle senses a
loss of traction.
When additional traction is required, the transfer case
LOW RANGE position can be used to lock the front and
rear driveshafts together forcing the front and rear wheels
to rotate at the same speed. This is accomplished by
rotating the AWD Control Switch to the desired position.
Refer to “Shifting Procedure” for specific shifting instruc-
tions. The LOW RANGE position is designed for loose,
slippery road surfaces only. Driving in the LOW RANGE
position on dry hard surfaced roads may cause increased
tire wear and damage to the driveline components.
Transfer Case Position Indicator Messages
The Transfer Case Position Indicator messages (AWD
AUTO and LOW RANGE) are located in the instrument
cluster and indicate the current and desired transfer caseselection. Refer to “Instrument Cluster Display” in “Get-
ting To Know Your Instrument Panel” for further informa-
tion. When you select a different transfer case position, the
position indicator lights will do the following:
If All Shift Conditions Are Met:
1. The current position indicator light will turn OFF.
2. The selected position indicator light will flash until the
transfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and remain ON.
If One Or More Shift Conditions Are Not Met:
1. The indicator light for the current position will remain ON.
2. The newly selected position indicator light will continue to flash.
3. The transfer case will notshift.
282 STARTING AND OPERATING
NOTE:Before retrying a selection, make certain that all the
necessary requirements for selecting a new transfer case
position have been met. To retry the selection, turn the
control knob back to the current position, wait five sec-
onds, and retry selection. To find the shift requirements,
refer to the Shifting Procedure for your transfer case,
located in this section.
The “SERV AWD” Warning Light monitors the electronic
shift all-wheel drive system. If this light remains on after
engine start up or illuminates during driving, it means that
the all-wheel drive system is not functioning properly and
that service is required.
WARNING!
Always engage the parking brake when powering
down the vehicle if the “SERV AWD Warning Light” is
illuminated. Not engaging the parking brake may
allow the vehicle to roll which may cause personal
injury.
NOTE: Do not attempt to make a shift while only the front
or rear wheels are spinning. This could cause damage to
driveline components. When operating your vehicle in LOW RANGE, the engine
speed is approximately three times that of the AWD AUTO
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
Proper operation of all-wheel drive vehicles depends on
tires of equal size, type and circumference on each wheel.
Any difference in tire size can cause damage to the transfer
case.
Because all-wheel drive provides improved traction, there
is a tendency to exceed safe turning and stopping speeds.
Do not go faster than road conditions permit.
For additional information on the appropriate use of each
transfer case mode position, see the information below:
AWD Auto
All-Wheel Drive Auto Range – This range sends power to
the rear wheels. The all-wheel drive system will be auto-
matically engaged when the vehicle senses a loss of trac-
tion. Additional traction for varying road conditions.
6
STARTING AND OPERATING 283
LOW Range
All-Wheel Drive Low Range – This range provides low
speed all-wheel drive. Locks the front and rear driveshafts
together forcing the front and rear wheels to rotate at the
same speed. Additional traction and maximum pulling
power for loose, slippery road surfaces only. Do not exceed
25 mph (40 km/h).
NEUTRAL (N)
NEUTRAL – This range disengages both the front and rear
driveshafts from the powertrain. 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 transfer case in the NEU-
TRAL position without first fully engaging the park-
ing brake. The transfer case NEUTRAL position disen-
gages both the front and rear drive shafts 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.
Shifting Procedure
NOTE:
•If any of the requirements to select a new transfer case
position have not been met, the transfer case will not
shift. The position indicator light for the previous posi-
tion will remain ON and the newly selected position
indicator light will continue to flash until all the require-
ments for the selected position have been met. To retry a
shift: return the control switch back to the original
position, make certain all shift requirements have been
met, wait five seconds and try the shift again.
• If all the requirements to select a new transfer case
position have been met, the current position indicator
light will turn OFF, the selected position indicator light
will flash until the transfer case completes the shift.
When the shift is complete, the position indicator light
for the selected position will stop flashing and remain
ON.
AWD Auto To Low Range
NOTE: When shifting into or out of LOW RANGE some
gear noise may be heard. This noise is normal and is not
detrimental to the vehicle or occupants.
284 STARTING AND OPERATING
Shifting can be performed with the vehicle rolling 2 to
3 mph (3 to 5 km/h) or completely stopped. Use either of
the following procedures:
Preferred Procedure
1. With the engine running, slow the vehicle to 2 to 3 mph(3 to 5 km/h).
2. Shift the transmission into NEUTRAL.
3. While still rolling, rotate the AWD control switch to the desired position.
4. After the desired position indicator light is ON (not flashing), shift the transmission back into gear.
Alternate Procedure
1. Bring the vehicle to complete stop.
2. With the ignition switch in ON/ RUN position and engine running, shift the transmission to NEUTRAL.
3. Rotate the AWD control switch to the desired position.
4. After the desired position indicator light is ON (not flashing), shift the transmission back into gear. NOTE:
•
If steps 1 or 2 of either the Preferred or Alternate
Procedure are not satisfied prior to attempting the shift
or if they no longer are being met while the shift attempt
is in process, the desired position indicator light will
flash continuously while the original position indicator
light is ON, until all requirements have been met.
• The ignition switch must be in the RUN position for a
shift to take place and for the position indicator lights to
be operable. If the ignition switch is not in the RUN
position, then the shift will not take place and no
position indicator lights will be on or flashing.
NEUTRAL Shift Procedure
For information regarding the transfer case NEUTRAL (N)
shift procedure, refer to “Shifting Into NEUTRAL (N)” in
“Recreational Towing”.
FUEL SAVER TECHNOLOGY 5.7L ONLY — IF

STARTING AND OPERATING 285
NOTE:This system may take some time to return to full
functionality after a battery disconnect.
POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the
electric steering system experiences a fault that prevents it
from providing assist, you will still have the ability to steer
the vehicle manually.
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. Refer to ”Customer Pro-
grammable Features” within “Uconnect Settings” in “Mul-
timedia” for further information. If the Electric Power Steering warning icon is
displayed and the “SERVICE POWER STEER-
ING” or the “POWER STEERING ASSIST OFF – SERVICE SYSTEM” message is displayed within the in-
strument cluster display, this indicates the vehicle needs to
be taken to the dealer for service. Refer to “Warning Lights
And Messages” in “Getting To Know Your Instrument
Panel” for further information.
NOTE:
•
Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
• If the condition persists, see your authorized dealer for
service.
If the Steering icon is displayed and the “POWER STEER-
ING SYSTEM OVER TEMP” message is displayed on the
instrument cluster screen, they indicate that extreme steer-
ing maneuvers may have occurred which caused an over
temperature condition in the power steering system. Once
driving conditions are safe, pull over and let the vehicle
idle for a few moments until the icon and message turn off.
