WARNING!
inflate, even if they are in an infant or
child restraint.
• Seat belts (and child restraints where
appropriate) are necessary for your pro-
tection in all collisions. They also help
keep you in position, away from an in-
flating Side Air Bag. To get the best
protection from the Side Air Bags, occu-
pants must wear their seat belts properly
and sit upright with their backs against
the seats. Children must be properly
restrained in a child restraint or booster
seat that is appropriate for the size of the
child.
WARNING!
• Side Air Bags need room to inflate. Do
not lean against the door or window. Sit
upright in the center of the seat.
• Being too close to the Side Air Bags
during deployment could cause you to
be severely injured or killed.
• Relying on the Side Air Bags alone could
lead to more severe injuries in a colli-
WARNING!
sion. The Side Air Bags work with your
seat belt to restrain you properly. In
some collisions, Side Air Bags won’t
deploy at all. Always wear your seat belt
even though you have Side Air Bags.
NOTE:
Air bag covers may not be obvious in the
interior trim, but they will open during air bag
deployment.
Rollover Events (If Equipped With Rollover
Sensing)
Side Air Bags are designed to activate in
certain rollover events. The ORC determines
whether the deployment of the Side Air Bags
in a particular rollover event is appropriate,
based on the severity and type of collision.
Vehicle damage by itself is not a good indica-
tor of whether or not Side Air Bags should
have deployed.
The Side Air Bags will not deploy in all
rollover events. The rollover sensing system
determines if a rollover event may be in
progress and whether deployment is appro-priate. In the event the vehicle experiences a
rollover or near rollover event, and deploy-
ment of the Side Air Bags is appropriate, the
rollover sensing system will also deploy the
seat belt pretensioners on both sides of the
vehicle.
The SABICs may help reduce the risk of
partial or complete ejection of vehicle occu-
pants through side windows in certain roll-
over or side impact events.
Air Bag System Components
NOTE:
The Occupant Restraint Controller (ORC)
monitors the internal circuits and intercon-
necting wiring associated with electrical Air
Bag System Components listed below:
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters

and remove the key from the ignition switch
to avoid draining the battery. Carefully check
the vehicle for fuel leaks in the engine com-
partment and on the ground near the engine
compartment and fuel tank before resetting
the system and starting the engine. If there
are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the system by following the
procedure described below.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Re-
sponse System functions after an event, the
ignition switch must be changed from igni-
tion START or ON/RUN to ignition OFF. Care-
fully check the vehicle for fuel leaks in the
engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine.
Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bag
system could cause it to fail when you
need it. You could be injured if the air
bag system is not there to protect you.
Do not modify the components or wiring,
including adding any kind of badges or
stickers to the steering wheel hub trim
cover or the upper right side of the in-
strument panel. Do not modify the front
bumper, vehicle body structure, or add
aftermarket side steps or running
boards.
• It is dangerous to try to repair any part of
the air bag system yourself. Be sure to
tell anyone who works on your vehicle
that it has an air bag system.
• Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function prop-
erly if modifications are made. Take your
vehicle to an authorized dealer for any
air bag system service. If your seat, in-
cluding your trim cover and cushion,

cured to your vehicle using the floor mat
fasteners by lightly pulling mat.
Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones,
nails, glass, or other objects lodged in the
tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts,cracks, and bulges. Check the wheel nuts for
tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and lock-
ing.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or
if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected
immediately.

This system can also provide you with more
control during passing, city driving, cold slip-
pery conditions, mountain driving, trailer
towing, and many other situations.
Operation
To activate AutoStick mode, move the gear
selector into the MANUAL (M) position (be-
side the DRIVE position), or tap one of the
shift paddles on the steering wheel. Tapping
the (-) shift paddle to enter AutoStick mode
will downshift the transmission to the next
lower gear, while tapping (+) to enter
AutoStick mode will retain the current gear.
The current transmission gear will be dis-
played in the instrument cluster. In AutoStick
mode, you can use the gear selector (in the
MANUAL position), or the shift paddles, to
manually shift the transmission. Tapping thegear selector forward (-) while in the
MANUAL (M) position, or tapping the (-) shift
paddle, will downshift the transmission to the
next lower gear. Tapping the selector rear-
ward (+) (or tapping the (+) shift paddle) will
command an upshift.
NOTE:
The shift paddles may be disabled (or re-
enabled, as desired) using the Uconnect Per-
sonal Settings or, in SRT models, using Drive
Modes.
In AutoStick mode, the transmission will
shift up or down when (+/-) is manually se-
lected by the driver (using the 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 down-
shift as the vehicle slows (to prevent engine
lugging) and will display the current gear.• The transmission will automatically down-
shift 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 or third 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 hold-
ing the gear selector in the (-) position, will
downshift the transmission to the lowest
gear possible at the current speed.
• Transmission shifting will be more notice-
able when AutoStick is enabled.
• The system may revert to automatic shift
mode if a fault or overheat condition is
detected.
Shift Paddles
STARTING AND OPERATING

NOTE:
When Selec-Speed or Hill Descent Control is
enabled, AutoStick is not active.
To disengage AutoStick, return the gear se-
lector to the DRIVE position, or press and
hold the (+) shift paddle (if the gear selector
is already in DRIVE) until "D" is once again
indicated in the instrument cluster. You can
shift in or out of AutoStick at any time with-
out 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 ve-
hicle could skid, causing a collision or
personal injury.
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 modi-
fied shifting for an enhanced driving experi-
ence, as well the greatest amount of steeringfeel. This mode may be activated and deac-
tivated 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) transfer case, which provides conve-
nient full-time four-wheel drive. No driver
interaction is required. The Brake Traction
Control (BTC) System, which combines stan-
dard ABS and Traction Control, provides re-
sistance to any wheel that is slipping to allow
additional torque transfer to wheels with trac-
tion.
NOTE:
The Quadra-Trac I system is not appropriate
for conditions where 4WD LOW range is rec-
ommended. Refer to “Off-Road Driving Tips”
in “Starting And Operating” in the Owner’s
Manual.

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.

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
should always 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

8. After the NEUTRAL (N) button has been
released, the transfer case will shift to the
position indicated by the selector switch.
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
