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 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 of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could

WARNING!(Continued)
•Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and
a collision.
• Always fully apply the parking brake when leaving
your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
CAUTION!
If the “Brake” Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.

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.
• 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
turn the ignition OFF. When the ignition is in the
OFF mode, the transmission is locked in PARK,
securing the vehicle against unwanted movement.
• When leaving the vehicle, always make sure the
ignition is in the OFF mode, remove the key fob 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 unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to

light on the switch indicates when ECO mode is disabled
(for regular models) or a blue light when enabled (for SRT
models).
When the Fuel Economy (ECO) Mode is engaged, the
vehicle control systems will change the following:
•The transmission will upshift sooner and downshift
later.
• The overall driving performance will be more conserva-
tive. •
Vehicles with Quadra-Lift air suspension will operate in
Aero mode over a broader speed range. Refer to the
section on Quadra-Lift for further information.
• In SRT models, the transmission will launch (from a
stop) in second gear, and the torque converter clutch
may engage at lower engine speeds and remain on
longer.
• Some ECO mode functions may be temporarily inhib-
ited based on temperature and other factors.
Active Noise Cancellation — Summit And SRT
Models Only
Your vehicle is equipped with an Active Noise Cancellation
System. This system uses four microphones embedded 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
beside the gear selector and in the instrument cluster. To
select a gear range, press the lock button on the gear
selector and move the selector rearward or forward. To

•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 selector
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 “In Case Of Emergency” for
further information.
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. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.

gear selector, or the shift paddles), unless an engine lug-
ging 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, or holding the gear
selector in the (-) position, will downshift the transmis-
sion to the lowest gear possible at the current 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 en-
abled, AutoStick is not active.
To disengage AutoStick, return the gear selector to the
DRIVE position, or press and hold the (+) shift paddle (if
the gear selector is already in DRIVE) until Dis once
again indicated in the instrument cluster. You can shift in or
out of AutoStick at any time without taking your foot off
the accelerator pedal.
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.
282 STARTING AND OPERATING

SPORT MODE — IF EQUIPPED
Your vehicle is equipped with a Sport Mode feature. This
mode is a configuration set up for typical enthusiast
driving. The engine, transmission, and steering systems are
all set to their SPORT settings. Sport Mode will provide
improved throttle response and modified shifting for an
enhanced driving experience, as well the greatest amount
of steering feel. This mode may be activated and deacti-
vated by pushing the Sport button on the instrument panel
switch bank.
FOUR WHEEL DRIVE OPERATION
Quadra-Trac I Operating Instructions/Precautions —
If Equipped
The Quadra-Trac I is a single-speed (HI range only) trans-
fer case, which provides convenient full-time four-wheel
drive. No driver interaction is required. The Brake Traction
Control (BTC) System, which combines standard ABS and
Traction Control, provides resistance to any wheel that is
slipping to allow additional torque transfer to wheels with
traction.NOTE:
The Quadra-Trac I system is not appropriate for
conditions where 4WD LOW range is recommended. Refer
to “Off-Road Driving Tips” in “Starting And Operating”
for further information.
Quadra-Trac II Operating Instructions/Precautions
— If Equipped
The Quadra-Trac II transfer case is fully automatic in the
normal driving 4WD AUTO mode. The Quadra-Trac II
transfer case provides three mode positions:
• 4WD HI
• NEUTRAL
• 4WD LOW
This transfer case is fully automatic in the 4WD HI mode.
When additional traction is required, the 4WD LOW
position can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at the
same speed. The 4WD LOW position is intended for loose,
slippery road surfaces only. Driving in the 4WD LOW
position on dry, hard-surfaced roads may cause increased
tire wear and damage to driveline components.
