If the “SERVICE STOP/START SYSTEM” message ap-
pears in the DID, have the system checked by your
authorized dealer.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
The engine block heater cord is located:
•3.6L Engine — Coiled and strapped to the engine oil
dipstick tube.
• 5.7L Engine — Bundled and fastened to the injector
harness.
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.

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,
and make sure the keyless ignition node is in the
OFF mode. Remove the Key Fob from the vehicle,
and lock the vehicle. When the keyless ignition is
in the OFF mode, the transmission is locked in
PARK, securing the vehicle against unwanted
movement.
• 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.
• When leaving the vehicle, always make sure the
keyless ignition node is in the “OFF” mode, re-
move the key fob from the vehicle and lock the
vehicle.
• 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 the ACC or ON/RUN mode. A
child could operate power windows, other controls,
or move the vehicle.
466 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, 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

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.
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 four-wheel drive vehicles be sure that the
transfer case is in a drive position.WARNING!
• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment 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 leaving 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

seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the 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 the ACC or ON/RUN mode. A
child could operate power windows, other controls,
or move the vehicle.
472 STARTING AND OPERATING

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

brake and shift the transmission into PARK if you must
leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteris-
tics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing a heavy trailer), use the AutoStick shift
control (refer to
AutoStickin this section for further
information) to select a lower gear. Under these condi-
tions, using a lower gear will improve performance and
extend transmission life by reducing excessive shifting
and heat buildup.
