CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
•
Do not shift between PARK, REVERSE, NEUTRAL,
or DRIVE when the engine is above idle speed.
• Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
Ignition Park Interlock
This vehicle is equipped with a Ignition Park Interlock
which requires the transmission to be in PARK before the
engine can be turned off. This helps the driver avoid inadvertently leaving the vehicle without placing the
transmission in PARK.
This system also locks the transmission in PARK when-
ever the ignition switch is in the OFF position.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the gear selector in
PARK unless the brakes are applied. To shift the trans-
mission 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.

STARTING AND OPERATING 467

Active Noise Cancellation — Summit And SRT
Models Only
Your vehicle is equipped with an Active Noise Cancella-
tion System. This system uses four microphones embed-
ded in the headliner to detect undesirable exhaust noise,
which sometimes occurs when operating in ECO mode.
An onboard frequency generator creates counteracting
sound waves through the audio system to help keep the
vehicle quiet.
Eight–Speed Automatic Transmission
The transmission gear range (PRNDM) is displayed both
on the gear selector bezel and in the Driver Information
Display (DID). To select a gear range, press the lock
button on the gear selector and move the lever rearward
or forward. You must also press the brake pedal to shift
the transmission out of PARK, or to shift from NEUTRAL
into DRIVE or REVERSE when the vehicle is stopped ormoving at low speeds (refer to “Brake/Transmission
Shift Interlock System” in this section). Select the DRIVE
range for normal driving.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when
shifting between these gears.
The transmission gear selector provides PARK, RE-
VERSE, NEUTRAL, DRIVE and MANUAL (AutoStick)
shift positions. Manual shifts can be made using the
AutoStick shift control (refer to “AutoStick” in this
5
STARTING AND OPERATING 469

CAUTION!
•DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as this
can damage the drivetrain.
• Before moving the gear selector out of PARK, you
must start the engine, and also press the brake
pedal. Otherwise, damage to the gear selector could
result.
The following indicators should be used to ensure that you
have engaged the transmission into the PARK position:
• When shifting into PARK, press the lock button on the
gear selector and push the lever all the way forward
until it stops and is fully seated.
• Look at the transmission gear position display and
verify that it indicates the PARK position (P). •
With brake pedal released, verify that the gear selector
will not move out of PARK.
NOTE: If the gear selector cannot be moved to the PARK
position (when pushed forward), it is probably in the
AutoStick (+/-) position (beside the DRIVE position). In
AutoStick mode, the transmission gear (1, 2, 3, etc.) is
displayed in the instrument cluster. Move the gear selec-
tor to the right (into the DRIVE [D] position) for access to
PARK, REVERSE, and NEUTRAL.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking

1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not,shift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine turns OFF.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to normal
operation.
NOTE:
Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your earliest
possible convenience. Your authorized dealer has diagnos-
tic equipment to determine if the problem could recur.
If the transmission cannot be reset, authorized dealer
service is required.
AutoStick
AutoStick is a driver-interactive transmission feature
providing manual shift control, giving you more control
of the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This system
can also provide you with more control during passing,
city driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
Operation
To activate AutoStick mode, move the gear selector into
the MANUAL (M) position (beside the DRIVE position),
or tap one of the shift paddles on the steering wheel.
Tapping the (-) shift paddle to enter AutoStick mode will
downshift the transmission to the next lower gear, while
tapping (+) to enter AutoStick mode will retain the
current gear. The current transmission gear will be dis-
played in the instrument cluster. In AutoStick mode, you
476 STARTING AND OPERATING

can use the gear selector (in the MANUAL position), or
the shift paddles, to manually shift the transmission.
Tapping the gear selector forward (-) while in the
MANUAL (M) position, or tapping the (-) shift paddle on
the steering wheel, will downshift the transmission to the
next lower gear. Tapping the lever rearward (+) (or
tapping the (+) shift paddle) will command an upshift.
NOTE:The shift paddles may be disabled (or re-enabled,
as desired) using the Uconnect Personal Settings.
In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver
(using the gear selector, or the shift paddles), unless an
engine lugging or overspeed condition would result. It
will remain in the selected gear until another upshift or
downshift is chosen, except as described below.
• The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear. •
The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
• You can start out, from a stop, in first or second gear
(or third gear, in 4LO range, Snow mode, or Sand
mode). Tapping (+) (at a stop) will allow starting in
second gear. Starting out in second gear can be helpful
in snowy or icy conditions.
• If a requested downshift would cause the engine to
over-speed, that shift will not occur.
• The system will ignore attempts to upshift at too low
of a vehicle speed.
• Holding the (-) paddle depressed will downshift the
transmission to the lowest gear possible at the current
speed.
5
STARTING AND OPERATING 477

When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
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 four-wheel drive vehicles depends
on tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the

WARNING!(Continued)
parking brake. The transfer case NEUTRAL position
disengages 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.
Shift Positions
For additional information on the appropriate use of each
4WD system mode position, see the information below:
4WD AUTO
This range is used on surfaces such as ice, snow, gravel,
sand, and dry hard pavement.
NOTE:Refer to “Selec-Terrain – If Equipped” in “Start-
ing And Operating” for further information on the vari-
ous positions and their intended usages.
480 STARTING AND OPERATING

NOTE:
•If shift conditions/interlocks are not met, or a transfer
case motor temperature protection condition exists, a
“For 4x4 High Slow Below 3 mph (5 km/h) Put Trans
in N push 4 Low” message will flash from the Driver
Information Display (DID). Refer to “Driver Informa-
tion Display (DID)” in “Understanding Your Instru-
ment 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 prop-
erly 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 transfer case will not allow
the shift.Shifting Into NEUTRAL (N)
WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the
NEUTRAL (N) position without first fully engaging
the parking brake. The NEUTRAL (N) position dis-
engages 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.
1. Bring the vehicle to a complete stop, with the engine running.
2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL.

STARTING AND OPERATING 485

Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4WD LOW if necessary.
Refer to “Four-Wheel Drive Operation” in “Starting and
Operating” for further information. Do not shift to a
lower gear than necessary to maintain forward motion.
Over-revving the engine can spin the wheels and traction
will be lost.
Avoid abrupt downshifts on icy or slippery roads, be-
cause engine braking may cause skidding and loss of
control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side. Before climbing a steep hill,
shift the transmission to a
lower gear and shift the transfer case to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
If you stall or begin to lose forward motion while
climbing a steep hill, allow your vehicle to come to a stop
and immediately apply the brakes. Restart the engine,
and shift into REVERSE. Back slowly down the hill,
allowing the compression braking of the engine to help
regulate your speed. If the brakes are required to control
vehicle speed, apply them lightly and avoid locking or
skidding the tires.
WARNING!
If the engine stalls, you lose forward motion, or
cannot make it to the top of a steep hill or grade,
never attempt to turn around. To do so may result in
