WARNING!
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build up may cause serious injury
or death.
• When leaving the vehicle, always make
sure the keyless ignition node 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 un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the gear selector.
STARTING AND OPERATING
152

300 to 500 miles (483 to 805 km):
• Exercise the full engine rpm range, shift-ing manually (paddles or gear shift) at
higher rpms when possible.
• Do not perform sustained operation with the accelerator pedal at wide open
throttle.
• Maintain vehicle speed below 85 mph (136 km/h) and observe local speed
limits.
For the first 1500 miles (2414 km):
• Do not participate in track events, sport driving schools, or similar activities during
the first 1500 mi (2414 km).
NOTE:
Check engine oil with every refueling and add
if necessary. Oil and fuel consumption may
be higher through the first oil change interval.
Running the engine with an oil level below
the add mark can cause severe engine dam-
age.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
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 run-
ning. Before exiting a vehicle, always
apply the parking brake, shift the trans-
mission 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 un-
wanted movement.
WARNING!
• When leaving the vehicle, always makesure 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 un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously 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 the ACC or ON/RUN mode. A child
could operate power windows, other con-
trols, or move the vehicle.
157

CAUTION!
Damage to the transmission may occur if
the following precautions are not ob-
served:
• Shift into or out of PARK or REVERSEonly 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 ignition can be turned
to the OFF mode. This helps the driver avoid
inadvertently leaving the vehicle without placing the transmission in PARK. This sys-
tem also locks the transmission in PARK
whenever the ignition is in the OFF mode.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Trans-
mission Shift Interlock system (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission 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.
Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve
the vehicle's overall fuel economy during nor-
mal driving conditions. Push the “ECO”
switch in the center stack of the instrument
panel to activate or disable ECO mode. An
amber 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 en-
gaged, the vehicle control systems will
change the following:
• The transmission will upshift sooner and
downshift later.
• The overall driving performance will be more conservative.
• 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.
ECO SwitchSTARTING AND OPERATING
158

• In SRT models, the transmission willlaunch (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 tempo- rarily inhibited 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 cre-
ates counteracting sound waves through the
audio system to help keep the vehicle quiet.
Eight–Speed Automatic Transmission
Your vehicle is equipped with a fuel efficient
8 speed transmission. The gear selector is
located in the center console. The transmission gear selector provides
PARK, REVERSE, NEUTRAL, DRIVE and
MANUAL (AutoStick) shift positions. Manual
shifts can be made using the AutoStick shiftcontrol (refer to “AutoStick” in this section
for further information). Toggling the gear
selector forward (-) or rearward (+) while in
the MANUAL (AutoStick) position (beside
the DRIVE position), or tapping the shift
paddles (+/-), will manually select the trans-
mission gear, and will display the current gear
in the instrument cluster.
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 transmis-
sion 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.

Quadra-Trac II Operating Instructions/
Precautions — If Equipped
The Quadra-Trac II transfer case is fully au-
tomatic in the normal driving 4WD AUTO
mode. The Quadra-Trac II transfer case pro-
vides 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 in-
tended 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.When operating your vehicle in 4WD LOW,
the engine speed is approximately three
times that of the 4WD HI position at a given
road speed. Take care not to overspeed the
engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference
will adversely affect shifting and cause dam-
age to the transfer case.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go faster
than road conditions permit.
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
transfer case in the NEUTRAL position
without first fully engaging the parking
brake. The transfer case NEUTRAL posi-
tion disengages both the front and rear
drive shafts from the powertrain and will
allow the vehicle to roll, even if the trans-
mission is in PARK. The parking brake
WARNING!
should always be applied when the driver
is not in the vehicle.
Shift Positions
For additional information on the appropriate
use of each 4WD system mode position, see
the information below:
4WD AUTO
This range is used on surfaces such as ice,
snow, gravel, sand, and dry hard pavement.
NOTE:
Refer to “Selec-Terrain – If Equipped” fur-
ther on in this section for further information
on the various positions and their intended
usages.
NEUTRAL
This range disengages the driveline from the
powertrain. It is to be used for flat towing
behind another vehicle. Refer to “Recre-
ational Towing” in “Starting And Operating”
for further information.
STARTING AND OPERATING
162

WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
power transfer unit in the NEUTRAL (N)
position without first fully engaging the
parking brake. The NEUTRAL (N) position
disengages both the front and rear drive-
shafts from the powertrain and will allow
the vehicle to roll, even if the transmission
is in PARK. The parking brake should al-
ways be applied when the driver is not in
the vehicle.
4WD LOW
This range is for low speed four-wheel drive. It
provides an additional gear reduction which
allows for increased torque to be delivered to
both the front and rear wheels while providing
maximum pulling power for loose, slippery
road surfaces only. Do not exceed 25 mph
(40 km/h).
NOTE:
Refer to “Selec-Terrain – If Equipped” for
further information on the various positions
and their intended usages.
Shifting Procedures
4WD HI To 4WD LOW

5 km/h), the ignition switch in the ON posi-
tion or the engine running, shift the transmis-
sion into “N”, and push the “4WD LOW”
button once on the transfer case switch. The
“4WD LOW” indicator light in the instrument
cluster will begin to flash and remain on solid
when the shift is complete.NOTE:
If shift conditions/interlocks are not met, or a
transfer case motor temperature protection
condition exists, a “For 4x4 Low Slow Below
3 mph (5 km/h) Put Trans in “N” Press
4 Low” message will flash from the instru-
ment cluster display. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.

push 4 Low” message will flash from the
instrument cluster display. Refer to “In-
strument Cluster Display” in “Getting To
Know Your Instrument Panel” for further
information.
• Shifting into or out of 4WD LOW is pos- sible with the vehicle completely stopped;
however, difficulty may occur due to the
mating clutch teeth not being properly
aligned. Several attempts may be required
for clutch teeth alignment and shift
completion to occur. The preferred
method is with the vehicle rolling 0 to
3 mph (0 to 5 km/h). If the vehicle is
moving faster than 3 mph (5 km/h), the
transfer case will not allow the shift.Shifting Into NEUTRAL (N)
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position
without first fully engaging the parking
brake. The NEUTRAL (N) position disen-
gages both the front and rear drive shafts
from the powertrain and will allow the
vehicle to roll, even if the transmission is
in PARK. The parking brake should always
be applied when the driver is not in the
vehicle.
1. Bring the vehicle to a complete stop, with the engine running.
2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL.

Quadra-Drive II System — If Equipped
The optional Quadra-Drive II System features
two torque transfer couplings. The couplings
include an Electronic Limited-Slip Differen-
tial (ELSD) rear axle and the Quadra-Trac II
transfer case. The optional ELSD axle is fully
automatic and requires no driver input to
operate. Under normal driving conditions,
the unit functions as a standard axle, balanc-
ing torque evenly between left and right
wheels. With a traction difference between
left and right wheels, the coupling will sense
a speed difference. As one wheel begins to
spin faster than the other, torque will auto-
matically transfer from the wheel that has
less traction, to the wheel that has traction.
While the transfer case and axle coupling
differ in design, their operation is similar.
Follow the Quadra-Trac II transfer case shift-
ing information, preceding this section, for
shifting this system.

flashing yellow. At this time torque is ap-
plied to the steering wheel in the opposite
direction of the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right.
NOTE:
The LaneSense system operates with the
similar behavior for a right lane departure.
Changing LaneSense Status
The LaneSense system has settings to adjust
the intensity of the torque warning and the
warning zone sensitivity (early/late) that you
can configure through the Uconnect system
screen. Refer to “Uconnect Settings” in
“Multimedia” for further information.
NOTE:
• When enabled the system operates above 37 mph (60 km/h) and below 112 mph
(180 km/h).
• Use of the turn signal suppresses the warnings. • The system will not apply torque to the
steering wheel whenever a safety system
engages. (anti-lock brakes, traction con-
trol system, electronic stability control,
forward collision warning, etc.).
PARKVIEW REAR BACK-UP
