How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulderbelt.
2. Grasp the shoulder portion and pull down- ward until the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking
sound. This indicates the seat belt is now
in the Automatic Locking Mode.
How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disen-
gage the Automatic Locking Mode and acti-
vate the vehicle sensitive (emergency) lock-
ing mode.
WARNING!
• The seat belt assembly must be replaced if the switchable Automatic Locking Re-
tractor (ALR) feature or any other seat
belt function is not working properly
when checked according to the proce-
dures in the Service Manual.
WARNING!
• Failure to replace the seat belt assemblycould increase the risk of injury in colli-
sions.
• Do not use the Automatic Locking Mode
to restrain occupants who are wearing
the seat belt or children who are using
booster seats. The locked mode is only
used to install rear-facing or forward-
facing child restraints that have a har-
ness for restraining the child.
Supplemental Restraint Systems
(SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask your autho-
rized dealer.
The air bag system must be ready to protect
you in a collision. The Occupant Restraint
Controller (ORC) monitors the internal cir-
cuits and interconnecting wiring associated with the electrical Air Bag System Compo-
nents. Your vehicle may be equipped with the
following Air Bag System Components:
Air Bag System Components
• 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 — If Equipped
• Front and Side Impact Sensors — If
Equipped
• Seat Belt Pretensioners — If Equipped
Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system when-
ever the ignition switch is in the START or
87
Page 90 of 298
ON/RUN position. If the ignition switch is in
the OFF position or in the ACC position, the
air bag system is not on and the air bags will
not inflate.
The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light
in the instrument panel for approximately
four to eight seconds for a self-check when
the ignition switch is first in the ON/RUN
position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects
a malfunction in any part of the system, it
turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime
will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag
Warning Light if a malfunction is detected
that could affect the air bag system. The
diagnostics also record the nature of the
malfunction. While the air bag system isdesigned to be maintenance free, if any of
the following occurs, have an authorized
dealer service the air bag system immedi-
ately.
• The Air Bag Warning Light does not come
on during the four to eight seconds when
the ignition switch is first in the ON/RUN
position.
• The Air Bag Warning Light remains on after the four to eight-second interval.
• The Air Bag Warning Light comes on inter- mittently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any en-
gine related gauges are not working, the Oc-
cupant Restraint Controller (ORC) may also
be disabled. In this condition the air bags
may not be ready to inflate for your protec-
tion. Have an authorized dealer service the
air bag system immediately.WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t
have the air bag system to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first
turned on, stays on after you start the
vehicle, or if it comes on as you drive, have
an authorized dealer service the air bag
system immediately.
Front Air Bags
This vehicle has front air bags and lap/
shoulder belts for both the driver and front
passenger. The front air bags are a supple-
ment to the seat belt restraint systems. The
driver front air bag is mounted in the center
of the steering wheel. The passenger front air
bag is mounted in the instrument panel,
above the glove compartment. The words
“SRS AIRBAG” or “AIRBAG” are embossed
on the air bag covers.

• Front and Side Impact Sensors — IfEquipped
• Seat Belt Pretensioners — If Equipped
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.
• Flash hazard lights as long as the batteryhas power or until the hazard light button is
pressed. The hazard lights can be deacti-
vated by pressing the hazard light button.
• Turn on the interior lights, which remain on as long as the battery has power.
• Unlock the power door locks.

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 bagsystem 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.
WARNING!
• It is dangerous to try to repair any part ofthe 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,
needs to be serviced in any way (includ-
ing removal or loosening/tightening of
seat attachment bolts), take the vehicle
to your authorized dealer. Only manufac-
turer approved seat accessories may be
used. If it is necessary to modify the air
bag system for persons with disabilities,
contact your authorized dealer.
Event Data Recorder (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in
understanding how a vehicle’s systems per-
formed. The EDR is designed to record data
related to vehicle dynamics and safety sys-
tems for a short period of time, typically
30 seconds or less. The EDR in this vehicle is
designed to record such data as:
• How various systems in your vehicle were
operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur.

The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the com-
plete exhaust system and adjacent body ar-
eas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In
addition, inspect the exhaust system each
time the vehicle is raised for lubrication or oil
change. Replace as required.
Safety Checks You Should Make
Inside The Vehicle
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced immedi-
ately. Do not disassemble or modify the sys-
tem.Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies
must be replaced after a collision if they have
been damaged (i.e., bent retractor, torn web-
bing, etc.). If there is any question regarding
seat belt or retractor condition, replace the
seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for
four to eight seconds as a bulb check when
the ignition switch is first turned to ON/RUN.
If the light is either not on during starting,
stays on, or turns on while driving, have the
system inspected at your authorized dealer as
soon as possible. After the bulb check, this
light will illuminate with a single chime when
a fault with the Air Bag System has been
detected. It will stay on until the fault is
cleared. If the light comes on intermittently
or remains on while driving, have your autho-
rized dealer service the vehicle immediately.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
Defroster
Check operation by selecting the defrost
mode and place the blower control on high
speed. You should be able to feel the air
directed against the windshield. See your
authorized dealer for service if your defroster
is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your
vehicle. Only use a floor mat that does not
interfere with the operation of the accelera-
tor, brake or clutch pedals. Only use a floor
mat that is securely attached using the floor
mat fasteners so it cannot slip out of position
and interfere with the accelerator, brake or
clutch pedals or impair safe operation of your
vehicle in other ways.
WARNING!
An improperly attached, damaged, folded,
or stacked floor mat, or damaged floor mat
fasteners may cause your floor mat to
interfere with the accelerator, brake, or
clutch pedals and cause a loss of vehicle

3. While the "Wait to Start" telltale is on, theinstrument cluster will additionally dis-
play a gauge or bar whose initial length
represents the full "Wait to Start" time
period. Its length will decrease until it
disappears when the "Wait to Start" time
has elapsed.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START engine before
you drain the water from the fuel filters to
avoid engine damage. Refer to “Draining
Fuel/Water Separator Filter” in “Dealer
Service” under “Servicing And Mainte-
nance” for further information.
4.
After the engine “Wait To Start” telltale goes
off, the engine will automatically crank.
CAUTION!
Do not crank engine for more than 15 seconds
at a time or starter motor damage may result.
Turn the ignition switch to the OFF position
and wait at least two minutes for the starter to
cool before repeating start procedure.
5. After engine start-up, check to see that there is oil pressure.
6. Allow the engine to idle about three min- utes until the manifold heaters have com-
pleted the post-heat cycle.
7. Release the parking brake and drive.
NOTE:
• Engine idle speed will automatically in- crease to 1,000 RPM and engage the Vari-
able Geometry Turbocharger at low coolant
temperatures to improve engine warm-up.
• The engine may not automatically crank after the engine "Wait To Start" telltale goes
off if a door or the hood is ajar.
• If the engine stalls, or if the ignition switch is left ON for more than two minutes after
the “Wait To Start Light” goes out, reset the
grid heaters by turning the ignition switch
to the OFF position for at least five seconds
and then back ON. Repeat steps 1 through
7 of “Keyless Enter-N-Go Starting Proce-
dure – Engine Manifold Air Temperature
Below 66° F (19° C).”Extreme Cold Weather
The Cummins diesel engine is equipped with
several features designed to assist cold
weather starting and operation:
• The engine block heater is a resistance
heater installed in the water jacket of the
engine just above and behind the oil filter.
It requires a 110–115 Volt AC electrical
outlet with a grounded, three-wire exten-
sion cord.
NOTE:
The engine block heater cord is a factory
installed option. If your vehicle is not
equipped, heater cords are available from
your authorized Mopar dealer.
• A 12 Volt heater built into the fuel filter housings aid in preventing fuel gelling. It is
controlled by a built-in thermostat.
• A heated intake air system both improves engine starting and reduces the amount of
white smoke generated by a warming
engine.

WARNING!
• 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 chil-
dren), and do not leave the ignition (in a
vehicle equipped with Keyless Enter-N-
Go) in the ACC or ON/RUN mode. A child
could operate power windows, other con-
trols, or move the vehicle.
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
• Shift into or out of PARK or REVERSE
only after the vehicle has come to a
complete stop.
CAUTION!
• 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.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition
Park Interlock which requires the transmis-
sion to be in PARK before the ignition can be
turned to the LOCK/OFF (key removal) posi-
tion. The key fob can only be removed from
the ignition when the ignition is in the LOCK/
OFF position, and the transmission is locked
in PARK whenever the ignition is in the
LOCK/OFF position. NOTE:
If a malfunction occurs, the system will trap
the key fob in the ignition to warn you that
this safety feature is inoperable. The engine
can be started and stopped but the key fob
cannot be removed until you obtain service.
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 ignition must
be in the ON/RUN mode (engine running or
not) and the brake pedal must be pressed.
Six–Speed Automatic
Transmission — If Equipped
Chassis Cab models (with automatic trans-
mission) may use either the AS66RC or
AS69RC transmission (which are equipped
with a Power Take-Off (PTO) access cover on
the side of the transmission case), or the
66RFE transmission (which has no PTO ac-
cess cover).
129
Page 132 of 298
The transmission gear position display (lo-
cated in the instrument cluster) indicates the
transmission gear range. The gear selector is
mounted on the right side of the steering
column. You must press the brake pedal to
move the gear selector out of PARK (refer to
“Brake/Transmission Shift Interlock System”
in this section). To drive, move the gear
selector from PARK or NEUTRAL to the
DRIVE position. Pull the gear selector toward
you when shifting into REVERSE or PARK, or
when shifting out of PARK.
The electronically-controlled transmission
provides a precise shift schedule. The trans-
mission 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 be-
tween these gears.The transmission gear selector has only
PARK, REVERSE, NEUTRAL, and DRIVE
shift positions. Manual downshifts can be
made using the Electronic Range Select
(ERS) shift control. Pushing the ERS (-/+)
switches (on the gear selector) while in the
DRIVE position will select the highest avail-
able transmission gear, and will display that
gear limit in the instrument cluster as 1, 2, 3,
etc. Refer to "Electronic Range Select (ERS)
Operation" in this section for further informa-
tion. Some models will display both the se-
lected gear limit, and the actual current gear,
while in ERS mode.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition is
detected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission remains
in fourth gear (for 66RFE transmission) or third
gear (for AS66RC/AS69RC transmission) re-
gardless of which forward gear is selected. If an
AS66RC/AS69RC equipped truck enters Limp
Home Mode at highway speeds, it will initially
engage fifth gear, until the vehicle slows to a speed where third gear can be engaged. PARK,
REVERSE, and NEUTRAL will continue to op-
erate. The Malfunction Indicator Light (MIL)
may be illuminated. Limp Home Mode allows
the vehicle to be driven to an authorized dealer
for service without damaging the transmission.
In the event of a momentary problem, the
transmission can be reset to regain all for-
ward gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the trans-
mission will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible convenience.
Your authorized dealer has diagnostic equip-
ment to assess the condition of your trans-
mission.
STARTING AND OPERATING
130
Page 133 of 298
If the transmission cannot be reset, autho-
rized dealer service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift con-
trol allows the driver to limit the highest
available gear when the transmission is in
DRIVE. For example, if you set the transmis-
sion gear limit to 4 (fourth gear), the trans-
mission will not shift above fourth gear, but
will shift through the lower gears normally.
You can switch between DRIVE and ERS
mode at any vehicle speed. When the gear
selector is in the DRIVE position, the trans-
mission will operate automatically, shifting
between all available gears. Tapping the ERS
(-) switch will activate ERS mode, display the
current gear in the instrument cluster, and
set that gear as the top available gear. Once
in ERS mode, tapping (-) or (+) will change
the top available gear.To exit ERS mode, simply push and hold the
ERS (+) switch until the gear limit display
disappears from the instrument cluster.
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.
NOTE:
To select the proper gear position for maxi-
mum deceleration (engine braking), simply
push and hold the ERS (-) switch. The trans-
mission will shift to the range from which the
vehicle can best be slowed down.
CAUTION!
When using ERS for engine braking while
descending steep grades, be careful not to
overspeed the engine. Apply the brakes as
needed to prevent engine overspeed.
FOUR-WHEEL DRIVE OPERATION —
IF EQUIPPED
• Four-wheel drive trucks are equipped with either a manually shifted transfer case or an
electronically shifted transfer case. Refer to
the operating instructions for electronic
transfer case, located in this section for
further information.
• For further information on the manually shifted transfer case, refer to “Four Wheel
Drive Operation” in “Starting And Operat-
ing” in your Owner’s Manual located at

DEF Fill Procedure
NOTE:
Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for the correct fluid type.
1. Remove cap from DEF tank (located ondrivers side of the vehicle or in fuel door). 2. Insert DEF fill adapter/nozzle into DEF
tank filler neck.
NOTE: • The DEF gauge may take up to five seconds to update after adding a gallon
or more of Diesel Exhaust Fluid (DEF)
to the DEF tank. If you have a fault
related to the DEF system, the gauge
may not update to the new level. See
your authorized dealer for service.
• The DEF gauge may also not immedi- ately update after a refill if the tempera-
ture of the DEF fluid is below 12F
(-11C). The DEF line heater will possi-
bly warm up the DEF fluid and allow the
gauge to update after a period of run
time. Under very cold conditions, it is
possible that the gauge may not reflect
the new fill level for several drives.
CAUTION!
•To avoid DEF spillage, and possible dam-
age to the DEF tank from overfilling, do
not “top off” the DEF tank after filling.
• DO NOT OVERFILL. DEF will freeze be- low 12ºF (-11ºC). The DEF system is
designed to work in temperatures below
the DEF freezing point, however, if the
tank is overfilled and freezes, the system
could be damaged.
• When DEF is spilled, clean the area immediately with water and use an ab-
sorbent material to soak up the spills on
the ground.
• Do not attempt to start your engine if DEF is accidentally added to the diesel
fuel tank as it can result in severe dam-
age to your engine, including but not
limited to failure of the fuel pump and
injectors.
