WARNING!
and you could be injured because the air
bags may no longer be functional. The
protective covers for the air bag cushions
are designed to open only when the air
bags are inflating.
• Relying on the air bags alone could lead
to more severe injuries in a collision. The
air bags work with your seat belt to
restrain you properly. In some collisions,
air bags won’t deploy at all. Always wear
your seat belts even though you have air
bags.
Front Air Bag Operation
Front Air Bags are designed to provide addi-
tional protection by supplementing the seat
belts. Front air bags are not expected to
reduce the risk of injury in rear, side, or
rollover collisions. The front air bags will not
deploy in all frontal collisions, including
some that may produce substantial vehicle
damage — for example, some pole collisions,
truck underrides, and angle offset collisions.On the other hand, depending on the type
and location of impact, front air bags may
deploy in crashes with little vehicle front-end
damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and
damage by themselves are not good indica-
tors of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in
all collisions, and also are needed to help
keep you in position, away from an inflating
air bag.
When the ORC detects a collision requiring
the front air bags, it signals the inflator units.
A large quantity of non-toxic gas is generated
to inflate the front air bags.
The steering wheel hub trim cover and the
upper passenger side of the instrument panel
separate and fold out of the way as the air
bags inflate to their full size. The front air
bags fully inflate in less time than it takes to
blink your eyes. The front air bags then
quickly deflate while helping to restrain the
driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the
knees of the driver and front passenger, and
position the front occupants for improved
interaction with the front air bags.
WARNING!
• Do not drill, cut, or tamper with the knee
impact bolsters in any way.
• Do not mount any accessories to the
knee impact bolsters such as alarm
lights, stereos, citizen band radios, etc.
Supplemental Driver Knee Air Bag
This vehicle is equipped with a Supplemental
Driver Knee Air Bag mounted in the instru-
ment panel below the steering column. The
Supplemental Driver Knee Air Bag provides
enhanced protection during a frontal impact
by working together with the seat belts, pre-
tensioners, and front air bags.

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
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Supplemental Knee Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.NOTE:
Front and/or side air bags will not deploy in
all collisions. This does not mean something
is wrong with the air bag system.
If you do have a collision which deploys the
air bags, any or all of the following may occur:
• The air bag material may sometimes cause
abrasions and/or skin reddening to the oc-
cupants as the air bags deploy and unfold.
The abrasions are similar to friction rope
burns or those you might get sliding along a
carpet or gymnasium floor. They are not
caused by contact with chemicals. They are
not permanent and normally heal quickly.
However, if you haven’t healed significantly
within a few days, or if you have any blis-
tering, see your doctor immediately.
• As the air bags deflate, you may see some
smoke-like particles. The particles are a
normal by-product of the process that gen-
erates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area
with cool water. For nose or throat irritation,
move to fresh air. If the irritation continues,see your doctor. If these particles settle on
your clothing, follow the garment manufac-
turer’s instructions for cleaning.
Do not drive your vehicle after the air bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
WARNING!
Deployed air bags and seat belt preten-
sioners cannot protect you in another col-
lision. Have the air bags, seat belt preten-
sioners, and the seat belt retractor
assemblies replaced by an authorized
dealer immediately. Also, have the Occu-
pant Restraint Controller System serviced
as well.
NOTE:
• Air bag covers may not be obvious in the
interior trim, but they will open during air
bag deployment.
• After any collision, the vehicle should be
taken to an authorized dealer immediately.

Enhanced Accident Response System
In the event of an impact, if the communica-
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the ORC will determine whether to
have the Enhanced Accident Response Sys-
tem perform the following functions:
• Cut off fuel to the engine (If Equipped)
• Cut off battery power to the electric motor
(If Equipped)
• Flash hazard lights as long as the battery
has power
• Turn on the interior lights, which remain on
as long as the battery has power or for 15
minutes from the intervention of the En-
hanced Accident Response System.
• Unlock the power door locks.
Your vehicle may also be designed to perform
any of these other functions in response to
the Enhanced Accident Response System:
• Turn off the Fuel Filter Heater, Turn off the
HVAC Blower Motor, Close the HVAC Circu-
lation Door• Cut off battery power to the:
– Engine
– Electric Motor (if equipped)
– Electric power steering
– Brake booster
– Electric park brake
– Automatic transmission gear selector
– Horn
– Front wiper
– Headlamp washer pump
NOTE:
After an accident, remember to cycle the
ignition to the STOP (OFF/LOCK) position
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. If you have any
doubt, contact an authorized dealer.
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 passenger side of the
instrument panel. Do not modify the
front bumper, vehicle body structure, or
add aftermarket side steps or running
boards.

WARNING!
• NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These ob-
jects could change the position of the
floor mat and may cause interference
with the accelerator, brake, or clutch
pedals.
• If the vehicle carpet has been removed
and re-installed, always properly attach
carpet to the floor and check the floor
mat fasteners are secure to the vehicle
carpet. Fully depress each pedal to
check for interference with the accelera-
tor, brake, or clutch pedals then re-
install the floor mats.
• It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat
has been properly installed and is se-
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 locking.
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.

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 or SPORT (AutoStick) shift posi-tions. Manual shifts can be made using the
AutoStick shift control. Toggling the gear se-
lector forward (-) or rearward (+) while in the
MANUAL or SPORT (AutoStick) position (be-
side 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. Refer to
"AutoStick" in this section for further infor-
mation.
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.
AutoStick
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving
you more control of the vehicle. AutoStick
allows you to maximize engine braking, elimi-
nate undesirable upshifts and downshifts,and improve overall vehicle performance.
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) or SPORT (S)
position (beside 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 transmis-
sion to the next lower gear, while tapping (+)
to enter AutoStick mode will retain the cur-
rent gear. The current transmission gear will
be displayed in the instrument cluster. In
AutoStick mode, you can use the gear selec-
tor (in the MANUAL or SPORT position), orTransmission Gear Selector
Shift Paddles
157

the shift paddles, to manually shift the trans-
mission. Tapping the gear selector forward (-)
while in the MANUAL (M) or SPORT (S)
position, or tapping the (-) shift paddle, will
downshift the transmission to the next lower
gear. Tapping the selector rearward (+) (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.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.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 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 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.
Sport Mode Button
159

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 deliv-
ered 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.
