108STARTING AND OPERATING
NOTE:
The transmission electronics are self-cali -
brating; 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 (kilome -
ters).
In the event of a mismatch between the gear
selector position and the actual transmission
gear (for example, driver selects REVERSE (R)
while driving forward), the position indicator will
blink continuously until the selector is returned
to the proper position, or the requested shift can
be completed.
The electronically controlled transmission adapts
its shift schedule based on driver inputs, along
with environmental and road conditions.
The 9-speed transmission has been developed to
meet the needs of current and future FWD/AWD
vehicles. Software and calibration is refined to
optimize the customer’s driving experience and
fuel economy. By design, some vehicle and
driveline combinations utilize NINTH gear only in
very specific driving situations and conditions. 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,
REVERSE, NEUTRAL, DRIVE, and AutoStick (+/-)
shift positions. Manual shifts can be made using
the AutoStick shift control
Úpage 111. Moving the
gear selector into the AutoStick (+/-) position
(beside the DRIVE position) activates AutoStick
mode, providing manual shift control and
displaying the current gear in the instrument
cluster (as 1, 2, 3, etc.). Toggling the gear selector
forward (-) or rearward (+) while in the AutoStick
position will manually select the transmission gear.
NOTE:If the gear selector cannot be moved to the PARK,
REVERSE, or NEUTRAL 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
selector to the right (into the DRIVE [D] position) for
access to PARK, REVERSE, and NEUTRAL.
Gear Selector
Gear Ranges
Do not press the accelerator pedal when shifting
out of PARK or NEUTRAL.
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before acceler
-
ating. This is especially important when the engine
is cold.
PARK (P)
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never attempt to use PARK
while the vehicle is in motion. Apply the parking
brake when exiting the vehicle in this range.

STARTING AND OPERATING111
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 feature can also provide
you with more control during passing, city driving,
cold slippery conditions, mountain driving, trailer
towing, and many other situations.
Operation
When the gear selector is in the AutoStick position
(beside the DRIVE (D) position), it can be moved
forward and rearward. This allows the driver to
manually select the transmission gear being used.
Moving the gear selector forward (-) triggers a
downshift and rearward (+) an upshift. The current
gear is displayed in the instrument cluster.
In AutoStick mode, the transmission will shift up or
down when the driver moves the gear selector
rearward (+) or forward (-), 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.
6-speed transmissions will automatically
upshift when necessary to prevent engine
over-speed.
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 trans -
mission as the vehicle is accelerated.
You can start out, from a stop, in FIRST or
SECOND gear (or THIRD gear, in 6-speed
models, or in 4WD LOW, SNOW mode, or SAND
mode, where available). 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.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift mode
if a fault or overheat condition is detected.
NOTE:When Selec-Speed or Hill Descent Control is
enabled, AutoStick is not active.
To disengage AutoStick, return the gear selector to
the DRIVE position. You can shift in or out of the
AutoStick position at any time without taking your
foot off the accelerator pedal.
TRANSMISSION LIMP HOME MODE
Transmission function is monitored electronically
for abnormal 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 a fixed
gear, or may remain in NEUTRAL (N). The
Malfunction Indicator Light (MIL) may be
illuminated. Limp Home Mode may allow the
vehicle to be driven to an authorized dealer for
service without damaging the transmission.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK (P), if possible. If not, shift the transmission to
NEUTRAL.
3. Push and hold the ignition until the engine turns off.
4. Wait approximately 30 seconds.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.

22_MP_OM_EN_USC_t.book Page 111
112STARTING AND OPERATING
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
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission. If the transmission
cannot be reset, authorized dealer service is
required.
TORQUE CONVERTER CLUTCH
A feature designed to improve fuel economy has
been included in the automatic transmission on
your vehicle. A clutch within the torque converter
engages automatically at calibrated speeds. This
may result in a slightly different feeling or response
during normal operation in the upper gears. When
the vehicle speed drops or during some
accelerations, the clutch automatically
disengages.
NOTE:The torque converter clutch will not engage until
the engine and/or transmission is warm (usually
after 1 to 3 miles [2 to 5 km] of driving). Because
the engine speed is higher when the torque
converter clutch is not engaged, it may seem as if the transmission is not shifting properly when the
vehicle is cold. This is normal. The torque converter
clutch will function normally once the powertrain is
sufficiently warm.
FOUR-WHEEL DRIVE OPERATION —
IF EQUIPPED
JEEP® ACTIVE DRIVE
Your vehicle may be equipped with a Power
Transfer Unit (PTU). This system is automatic
with no driver inputs or additional driving skills
required. Under normal driving conditions, the
front wheels provide most of the traction. If the
front wheels begin to lose traction, power is shifted
automatically to the rear wheels. The greater the
front wheel traction loss, the greater the power
transfer to the rear wheels.
Additionally, on dry pavement under heavy throttle
input (where one may have no wheel spin), torque
will be sent to the rear in a preemptive effort to
improve vehicle launch and performance
characteristics.
Four-Wheel Drive (4x4)
The four-wheel drive (4WD) is fully automatic in
normal driving mode.
NOTE:It is not possible to carry out the change of mode
when the vehicle exceeds the speed of 75 mph
(120 km/h).
4WD Buttons
Enabling Four-Wheel Drive (4x4)
The buttons for the activation of four-wheel drive
are located on the center console and allow you to
select the following:
4WD LOCK
4WD LOW — (Trailhawk models only)
CAUTION!
All wheels must have the same size and type
tires. Unequal tire sizes must not be used.
Unequal tire size may cause failure of the Power
Transfer Unit.
1 — 4WD LOW (Trailhawk models only)
2 — 4WD LOCK
22_MP_OM_EN_USC_t.book Page 112
STARTING AND OPERATING113
Active Drive Control — If Equipped
The Power Transfer Unit (PTU) is locked to ensure
immediate availability of torque to the rear drive
axles. This feature is selectable in AUTO mode and
automatic in the other driving mode. 4WD LOCK
can be enabled by the following ways:
When the 4WD LOCK button is pushed.
When the Selec-Terrain switch is moved from
AUTO to any other off-road modes.
Active Drive With Low Control — (Trailhawk models
only)
The 4WD LOW mode helps to improve the off-road
performance in all modes. To enable 4WD LOW,
please follow the steps below:
Enabling 4WD LOW
With the vehicle stationary, the ignition in the ON/
RUN position or with the engine running, shift the
transmission into NEUTRAL and push the 4WD
LOW button once. The instrument cluster will
display the message “4WD LOW” once the shift is
complete.
NOTE:
Both LOCK and LOW LED lights will blink and
then become active on the buttons until the
shift is complete.
The instrument cluster display will illuminate the
4WD LOW icon. Disabling 4WD LOW
To disable the 4WD LOW mode, the vehicle must
be stationary and the transmission shifted into
NEUTRAL. Push the 4WD LOW button once.
SELEC-TERRAIN — IF EQUIPPED
Selec-Terrain combines the capabilities of the
vehicle control systems, along with driver input, to
provide the best performance for all terrains.
MODE SELECTION GUIDE
Selec-Terrain Switch
AUTO
: This four-wheel drive operation is a
continuous operation, is fully automatic and can
be used on and off road. This mode balances
traction to ensure maneuverability and acceler -
ation improvement compared to a vehicle with
two wheel drive. This mode also reduces fuel consumption, since it allows the disconnect of
the drive shaft where conditions permit.
SNOW
: This mode allows you to have greater
stability under conditions of bad weather. For
use on and off road on surfaces with poor trac-
tion, such as roads covered with 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.
SAND/MUD : For off-road driving or use on
surfaces with poor traction, such as dry sand
and roads covered by mud or wet grass. The
transmission is set to provide maximum trac -
tion.
ROCK : (Trailhawk only): This mode is only avail -
able in 4WD LOW range. The device sets the
vehicle to maximize traction and allow the
highest steering capacity for off-road surfaces.
This mode gives you the maximum performance
off-road. Use for low speed obstacles such as
large rocks, deep ruts, etc.
SPORT : This mode is only available in 4WD
AUTO, and alters the transmission's automatic
shift schedule for sportier driving. Upshift
speeds are increased to make full use of avail -
able engine power. Suspension settings are
optimized and steering assist is modified to
provide better handling performance.

122STARTING AND OPERATING
To Resume
If there is a set speed in memory, push the RES
(resume) button and remove your foot from the
accelerator pedal. The instrument cluster display
will show the last set speed.
Resume can be used at any speed above 20 mph
(32 km/h) when only Fixed Speed Cruise Control is
being used.
Resume can be used at any speed above 0 mph
(0 km/h) when ACC is active.
NOTE:
If your vehicle is at standstill longer than two
seconds, the driver will either have to push the
RES (resume) button, or apply the accelerator
pedal to reengage the Adaptive Cruise Control
(ACC) to the existing set speed
ACC cannot be resumed if there is a stationary
vehicle in front of your vehicle in close proximity.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set
speed by pushing the SET (+) button, or decrease
speed by pushing the SET (-) button.
U.S. Speed (mph)
Pushing the SET (+) , or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust in 5 mph incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust in 10 km/h incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
NOTE:When you override and push the SET (+) button or
SET (-) button, the new set speed will be the current
speed of the vehicle.
When ACC Is Active
When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the
vehicle.
The ACC system decelerates the vehicle to a full
stop when following the vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
after two seconds the driver will either have to
push the RES (resume) button, or apply the
accelerator pedal to reengage the ACC to the
existing set speed.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while climbing
uphill or descending downhill. This is normal
operation and necessary to maintain set speed.
When driving uphill and downhill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate too
sharply for safe operation. Failure to follow these
warnings can result in a collision and death or
serious personal injury.
22_MP_OM_EN_USC_t.book Page 122
STARTING AND OPERATING127
STATIONARY OBJECTS AND VEHICLES
ACC does not react to stationary objects or
vehicles. For example, ACC will not react in
situations where the vehicle you are following exits
your lane and the vehicle ahead is stopped in your
lane. It will consider this stopped vehicle a
stationary object as it did not previously detect
movement from it. Always be attentive and ready
to apply the brakes if necessary.
Stationary Object And Stationary Vehicle Example
TRAFFIC SIGN ASSIST SYSTEM —
IF EQUIPPED
The Traffic Sign Assist (TSA) system uses a camera
mounted on the windshield, as well as map data
when the vehicle is equipped with Navigation, to
detect recognizable road signs such as:
Speed limits
School zones
No passing zones
NOTE:
The TSA system will automatically display the
road sign detected in the unit of measurement
(mph or km/h) selected within Uconnect
Settings or within the instrument cluster display.
If no speed limit signs are detected, the system
will revert to the speed limit signs that are
stored in the Navigation system.
The system always checks the traffic signs indi -
cating the current speed limit signs. The system
is able to recognize and display up to two
different road signs in the instrument cluster
display.
ACTIVATION/DEACTIVATION
The TSA System can be enabled/disabled within
the Uconnect system through the Safety/Driver
Assistance menu. System ON is signaled by road
signs shown on the instrument cluster display.
NOTE:Even if the system is OFF, the speed limit sign will
be displayed when the driver selects it in the HOME
screen.
TRAFFIC SIGN ASSIST MODES
TSA has three selectable modes of operation that
are available through the Uconnect system.
Visual
When Visual is selected, the system will alert the
driver when the current speed of the vehicle
exceeds the detected speed limit by showing a
graphic in the instrument cluster display.
Visual + Chime
When Visual + Chime is selected, the system will
alert the driver when the current speed of the
vehicle exceeds the detected speed limit by
showing a graphic in the instrument cluster
display, and by sounding an audible alert. The
audible alert will last for 10 seconds, and the
visual alert will remain on as long as the vehicle is
exceeding the speed limit.

STARTING AND OPERATING129
(Continued)
HIGHWAY ASSIST SYSTEM — IF EQUIPPED
OPERATION
The Highway Assist system (HAS) is combined with
the Adaptive Cruise Control (ACC) system, and
centers the vehicle in the driving lane while
traveling on controlled access highways at speeds
up to 90 mph (145 km/h).
For ACC system operating instructions and system
limitations, see Ú page 118.
NOTE:
The driver should always obey traffic laws and
speed limits. Never drive above applicable
speed limit restrictions.
The driver can override HAS at any time by
braking, accelerating, or steering the vehicle.
Just like ACC, HAS will maintain a set speed as long
as the set distance between your vehicle and the
vehicle in front is maintained. HAS will also keep
your vehicle centered between the lane lines, and
monitor for other vehicles in adjacent lanes by
utilizing the Blind Spot Monitoring sensors. HAS uses sensors within the steering wheel to
measure driver attentiveness. HAS requires the
driver’s hands on the steering wheel at all times.
The system will generally aim to keep the vehicle
centered in the lane, but when the driver turns the
steering wheel (e.g. to move further away from a
large vehicle in the next lane) the system will
reduce its control and enter "co-steering" mode.
While in co-steering mode, the system will provide
reduced assistance and allow the driver to control
the path of the vehicle. Once the driver stops
providing input to the steering wheel, the system
will require a few seconds to fully resume lane
centering assistance, especially during curves.
WARNING!
The Highway Assist system is a convenience
system. It is not a substitute for active driver
involvement. It is always the driver’s
responsibility to be attentive of road traffic,
weather conditions, vehicle speed, distance to
the vehicle ahead, position in the lane compared
to other vehicles, and brake operation to ensure
safe operation of the vehicle under all road
conditions. Your complete attention is always
required while driving to maintain safe control of
your vehicle. Failure to follow these warnings can
result in a collision and death or serious
personal injury.
You should turn off the Highway Assist system:
When driving in complex driving situations
(e.g. urban environments, construction zones,
etc.), adverse weather (e.g. rain, snow, fog,
sleet, dust), or adverse road conditions
(e.g. heavy traffic, worn or missing lane
markings, etc.).
When entering a highway off ramp, when
driving on roads that are, icy, snow covered, or
slippery.
When circumstances do not allow safe driving
at a constant speed.
WARNING!
