AUTOMATIC TRANSMISSION
You must press and hold the brake pedal while
shifting out of PARK.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park
Interlock which requires the transmission to be
in PARK before the ignition can be turned to the
full STOP (OFF/LOCK) (key removal) position.
The key can only be removed from the ignition
when the ignition is in the STOP (OFF/LOCK)
position, and once removed, the transmission is
locked in PARK.
WARNING!
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 accel -
erate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and your
foot is firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with
all vehicles, you should never exit a vehicle
while the engine is running. Before exiting a
vehicle always come to a complete stop,
then apply the parking brake, shift the
transmission into PARK, turn the engine
OFF, and remove the ignition key. Once the
key is removed, the transmission is locked
in PARK, securing the vehicle against
unwanted movement.
When leaving the vehicle, always remove
the ignition key from the vehicle and lock
the vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the transmission gear
selector.
Do not leave the ignition key in or near the
vehicle (or in a location accessible to chil -
dren). A child could operate power
windows, other controls, or move the
vehicle.
WARNING! (Continued)CAUTION!
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.

STARTING AND OPERATING63
Brake/Transmission Shift Interlock (BTSI)
System
This vehicle is equipped with a BTSI that holds
the transmission gear selector in PARK unless
the brakes are applied. To shift the
transmission out of PARK, the ignition must be
in the MAR (ON/RUN) mode (engine running or
not) 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.
Nine-Speed Automatic Transmission
The transmission gear range (PRND) is
displayed both beside the gear selector and in
the instrument cluster display. To select a gear
range, push 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 NEUTRAL, when
the vehicle is stopped or moving at low speeds).
Select the DRIVE range for normal driving. NOTE:
In the event of a mismatch between the gear
selector position and the actual transmission
gear (for example, driver selects REVERSE 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 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 or
kilometers.
The nine-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
9th 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 Electronic
Range Select (ERS) shift positions. Manual
downshifts can be made using the ERS shift
control. Moving the gear selector into the ERS
(-/+) position (beside the DRIVE position)
activates ERS mode, displays the current gear
in the instrument cluster, and prevents
automatic upshifts beyond this gear. In ERS
mode, toggling the gear selector forward (-) or
rearward (+) will change the highest available
gear Ú
page 67.
NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position (when
pushed forward) it is probably in the ERS (+/-)
position (beside the DRIVE position). In ERS
mode, the transmission gear limit (1, 2, 3, etc.)
is displayed in the instrument cluster. Move the

66STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest
upshifts and downshifts, and the best fuel
economy. The transmission automatically
upshifts through all forward gears.
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 Electronic Range Select
(ERS) shift control to select a lower gear range
Úpage 67. Under these conditions, using a
lower gear range will improve performance and
extend transmission life by reducing excessive
shifting and heat buildup.
If the transmission temperature exceeds
normal operating limits, the transmission
controller may modify the transmission shift
schedule, reduce engine torque, and/or expand
the range of torque converter clutch
engagement. This is done to prevent
transmission damage due to overheating.
If the transmission becomes extremely hot, the
“Transmission Temperature Warning Light” may
illuminate and the transmission may operate
differently until the transmission cools down. During cold temperatures, transmission
operation may be modified depending on
engine and transmission temperature as well
as vehicle speed. This feature improves warm
up time of the engine and transmission to
achieve maximum efficiency. Engagement of
the torque converter clutch, and shifts into
8th or 9th gear, are inhibited until the
transmission fluid is warm Ú
page 67. Normal
operation will resume once the transmission
temperature has risen to a suitable level.
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. 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.
3. Turn the ignition OFF.
4. Wait approximately 10 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
recommend that you visit an authorized dealer
at your earliest possible convenience. An autho -
rized dealer has diagnostic equipment to
assess the condition of your transmission. If the
transmission cannot be reset, authorized dealer
service is required.

STARTING AND OPERATING67
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 transmission fluid 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
cold. This is normal. The torque converter clutch
will function normally once the transmission is
sufficiently warm.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows the driver to limit the highest available
gear. For example, if you set the transmission
gear limit to fifth gear, the transmission will not
shift above fifth gear, but will shift through the
lower gears normally. You can switch between DRIVE and ERS mode
at any vehicle speed. When the gear selector is
in the DRIVE position, the transmission will
operate automatically, shifting between all
available gears.
Moving the gear selector to the ERS position
(beside DRIVE) will activate ERS mode, display
the current gear in the instrument cluster, and
set that gear as the top available gear. Once in
ERS mode, moving the gear selector forward (-)
or rearward (+) will change the top available
gear, which will be displayed in the instrument
cluster.
To exit ERS mode, simply return the gear
selector to the DRIVE position.
NOTE:
To select the proper gear position for maximum
deceleration (engine braking), move the gear
selector into the ERS position, then simply press
and hold it forward (-). The transmission will
shift to the range from which the vehicle can
best be slowed down.
POWER STEERING
The standard power steering system will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will provide mechanical steering capability if
power assist is lost.
If for some reason the power assist is
interrupted, it will still be possible to steer your
vehicle. Under these conditions, you will
observe a substantial increase in steering
effort, especially at very low vehicle speeds and
during parking maneuvers.
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.

70STARTING AND OPERATING
To Resume Speed
To resume a previously set speed, push the
RES (+) button and release. Resume can be used
at any speed above 20 mph (32 km/h) up to the maximum speed of 100 mph (160 km/h).
To Deactivate
A tap on the brake pedal, pushing the CAN
button, or normal brake pressure will deactivate
the Cruise Control system without erasing the
set speed from memory.
Pushing the on/off button or turning the ignition
switch off erases the set speed from memory.
PARKSENSE REAR PARK ASSIST — IF
EQUIPPED
The ParkSense system provides an audible
indication of the distance between the rear
fascia/bumper and a detected obstacle when
backing up (e.g. during a parking maneuver)
Ú page 72.
The ParkSense system is automatically
activated when the transmission is placed into
REVERSE. As the distance from an obstacle
behind the vehicle decreases, the audible alert
becomes more frequent. Interaction With Trailer Towing
The ParkSense system is automatically
deactivated when a trailer equipped by Mopar is
hitched to the vehicle. The system will be
automatically activated as soon as the trailer is
removed. If it does not happen, turning the key
ignition switch to OFF and then to ON again
would be needed. If a non-Mopar trailer hitch is
mounted, the sensor deactivation cannot be
guaranteed.
ParkSense Rear Park Assist Sensors
The four ParkSense sensors, located in the rear
fascia/bumper, monitor the area behind the
vehicle that is within the sensors’ field of view.
The sensors can detect obstacles, in the
horizontal direction, from approximately
12 inches (30 cm) up to 55 inches (140 cm)
from the center of the rear fascia/bumper and
up to 24 inches (60 cm) from the corners of the
rear fascia/bumper, depending on the location,
type and orientation of the obstacle.
ParkSense Rear Park Assist Sensors Locations

If several obstacles are detected, the
ParkSense system indicates the nearest
obstacle.
The minimum height of a detectable obstacle
corresponds to the maximum height of an
obstacle that would clear the underside of the
vehicle during the parking maneuver.

Towing Tips
Before towing, practice turning, stopping, and
backing up the trailer in an area located away
from heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing.
The transmission controls include a drive
strategy to avoid frequent shifting when towing.
However, if frequent shifting does occur while in
DRIVE, use the Electronic Range Select (ERS)
shift control to select a lower gear range.
NOTE:
Using a lower gear range while operating the
vehicle under heavy loading conditions will
improve performance and extend transmission
life by reducing excessive shifting and heat
build up. This action will also provide better
engine braking.
Electronic Range Select (ERS)
When using the ERS shift control, select the
highest gear that allows for adequate perfor -
mance and avoids frequent downshifts. For
example, choose “5” if the desired speed can
be maintained. Choose “4” or “3” if needed
to maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce
vehicle speed as necessary to avoid
extended driving at high RPM. Return to a
higher gear range or vehicle speed when
grade and road conditions allow.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Cruise Control, if you experi -
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use Cruise Control in flat terrain and with
light loads to maximize fuel efficiency.
