•Battery charge is low.
•The vehicle is on a steep grade.
•Cabin heating or cooling is in process and an accept-
able cabin temperature has not been achieved.
•HVAC is set to full defrost mode at a high blower
speed.
•HVAC set to MAX A/C.
•Engine has not reached normal operating temperature.
•The transmission is not in a forward gear.

To Start The Engine While In Autostop Mode
While in a forward gear, the engine will start when the
brake pedal is released or the throttle pedal is depressed.
The transmission will automatically re-engage upon en-
gine restart.

STARTING AND OPERATING 477

Conditions That Will Cause The Engine To Start Auto-
matically While In Autostop Mode:
•The transmission selector is moved out of DRIVE.
•To maintain cabin temperature comfort.
•HVAC is set to full defrost mode.
•HVAC system temperature or fan speed is manually
adjusted.
•Battery voltage drops too low.
•Low brake vacuum (e.g. after several brake pedal
applications).
•STOP/START OFF switch is pressed.
•A STOP/START system error occurs.
•4WD system is put into 4LO mode.
Conditions That Force An Application Of The Electric
Park Brake While In Autostop Mode:
•The drivers door is open and brake pedal released.
•The drivers door is open and the drivers seat belt is
unbuckled.
•The engine hood has been opened.
•A STOP/START system error occurs.
If the Electric Park Brake is applied with the engine off,
the engine may require a manual restart and the electric
park brake may require a manual release (depress brake
pedal and press Electric Park Brake switch). Refer to
“Electronic Vehicle Information Center (EVIC)” or
“Driver Information Display (DID)” in “Understanding
Your Instrument Panel” for further information.
478 STARTING AND OPERATING

NOTE:
•The engine block heater cord is a factory installed
option. If your vehicle is not equipped, heater cords
are available from your authorized MOPAR® dealer.
•The engine block heater will require 110 Volts AC and
6.5 Amps to activate the heater element.
•The engine block heater must be plugged in at least
one hour to have an adequate warming effect on the
engine.
WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt
electrical cord could cause electrocution.
AUTOMATIC TRANSMISSION
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 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 engine is idling normally and your foot is
firmly pressing the brake pedal.

STARTING AND OPERATING 481

WARNING!(Continued)
•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 apply the
parking brake, shift the transmission into PARK,
turn the engine OFF, and remove the key fob. When
the ignition is in the LOCK/OFF (key removal)
position, the transmission is locked in PARK, se-
curing the vehicle against unwanted movement.
•When leaving the vehicle, always make sure the
ignition is in the OFF position, remove the key fob
from the vehicle, and lock the vehicle.
(Continued)
WARNING!(Continued)
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended 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 key fob in or near the vehicle (or
in a location accessible to children), and do not
leave the ignition (in a vehicle equipped with
Keyless Enter-N-Go™) in the ACC or ON/RUN
position. A child could operate power windows,
other controls, or move the vehicle.
482 STARTING AND OPERATING

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, NEU-
TRAL, 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.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the ignition switch can be turned to the LOCK/
OFF (key removal) position. The key fob can only be
removed from the ignition when the ignition is in the
LOCK/OFF position, and the transmission is locked in
PARK whenever the ignition switch is in the LOCK/OFF
position.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the shift lever in PARK
unless the brakes are applied. To shift the transmission
out of PARK, the ignition switch must be turned to the
ON/RUN position (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.

Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve the vehi-
cle’s overall fuel economy during normal driving condi-
tions. To activate ECO mode press the “Controls” button
on the touchscreen and then press the “ECO” button on
the touchscreen. When ECO mode is engaged a green
light in the center stack of the instrument panel will be
illuminated and a green ECO light will also illuminate in
the Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID). In 4WD models, ECO
mode is only active in ’4WD Auto’ driving mode. If you
switch to another driving mode the ECO button will turn
grey and the ECO light in the instrument panel will
disappear indicating it is no longer in ECO mode. It will
automatically re-enable ECO mode when you switch
back into 4WD Auto.
Nine-Speed Automatic Transmission
The transmission gear range (PRND) is displayed both
beside the shift lever and in the Electronic Vehicle Infor-
mation Center (EVIC)/Driver Information Display
(DID). To select a gear range, press the lock button on the
shift lever 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 or moving at low
speeds (refer to#Brake/Transmission Shift Interlock Sys-
tem#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).
484 STARTING AND OPERATING

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 shift lever has PARK, REVERSE, NEU-
TRAL, DRIVE, and Electronic Range Select (ERS) shift
positions. Manual downshifts can be made using the ERS
shift control (refer to#Electronic Range Select (ERS)
Operation#in this section for further information). Mov-
ing the shift lever into the ERS (-/+) position (beside the
DRIVE position) activates ERS mode, displays the cur-
rent gear in the instrument cluster, and prevents auto-
matic upshifts beyond this gear. In ERS mode, toggling
the shift lever forward (-) or rearward (+) will change the
highest available gear.
NOTE:If the shift lever cannot be moved to the PARK,
REVERSE, or NEUTRAL position (when pushed for-
ward) 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 shift lever to the right (into the DRIVE [D]
position) for access to PARK, REVERSE, and NEUTRAL.

STARTING AND OPERATING 485

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
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 leaving the
vehicle in this range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.Shift Lever
