in the four-wheel drive LOW mode. The front
and rear driveshafts are mechanically locked
together forcing the front and rear wheels to
rotate at the same speed. Low range provides
a greater gear reduction ratio to provide in-
creased torque at the wheels.
Refer to “Four-Wheel Drive Operation — If
Equipped” in “Starting And Operating” for
further information on four-wheel drive op-
eration and proper use.
– 4WD Indicator Light —
If Equipped

— Wait To Start Light — If Equipped
The “Wait To Start” telltale will illuminate for
approximately two seconds when the ignition
is turned to the RUN position. It’s duration
may be longer based on colder operating
conditions. Vehicle will not initiate start until
telltale is no longer displayed. Refer to
“Starting The Engine” in “Starting And Op-
erating” for further information.
NOTE:
The “Wait To Start” telltale may not illumi-
nate if the intake manifold temperature is
warm enough.

• Signal interference due to electronic de-vices or driving next to facilities emitting
the same radio frequencies as the TPM
sensors.
• Installing aftermarket window tinting that contains materials that may block radio
wave signals.
• Accumulation of snow or ice around the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
A system fault may occur due to an incorrect
TPM sensor location condition. When a sys-
tem fault occurs due to an incorrect TPM
sensor location, the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for
75 seconds and then remain on solid. The
system fault will also sound a chime. In
addition, the instrument cluster will display a
“Tire Pressure Temporarily Unavailable”
message in place of the tire pressure display
screen. If the ignition switch is cycled, this
sequence will repeat, providing the system
fault still exists. If the system fault no longer
exists, the “Tire Pressure Monitoring Telltale Light” will no longer flash and the tire pres-
sure display screen will be displayed showing
the tire pressure values the correct locations.
Vehicles With Non Matching Full Size Spare Or
Compact Spare
• The non matching full size spare or com-
pact spare tire does not have a TPM sensor.
Therefore, the TPMS will not monitor the
pressure in the non matching full size spare
or compact spare tire.
• If you install the non matching full size spare or compact spare tire in place of a
road tire that has a pressure below the
low-pressure warning limit, upon the next
ignition switch cycle, the TPM Telltale
Light and a “LOW TIRE” message will re-
main ON and a chime will sound. In addi-
tion, the graphic in the instrument cluster
will still display a pressure value in a differ-
ent color.
• After driving the vehicle for up to 20 min- utes above 15 mph (24 km/h), the TPM
Telltale Light will flash on and off for
75 seconds and then remain on solid. In
addition, the instrument cluster will display a "SERVICE TPM SYSTEM" message for a
minimum of five seconds and then display
dashes (- -) in place of the pressure value.
• For each subsequent ignition switch cycle, a chime will sound, the TPM Telltale Light
will flash on and off for 75 seconds and
then remain on solid, and the instrument
cluster will display a "SERVICE TPM SYS-
TEM" message for a minimum of five sec-
onds and then display dashes (- -) in place
of the pressure value.
• Once you repair or replace the original road tire and reinstall it on the vehicle in place of
the non matching full size spare or compact
spare, the TPMS will update automatically.
In addition, the TPM Telltale Light will turn
OFF and the graphic in the instrument
cluster will display a new pressure value
instead of dashes (- -), as long as no tire
pressure is below the low-pressure warning
limit in any of the four active road tires. The
vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this
information.

Tire Pressure Information System (TPIS)
Chassis Cab — If Equipped
Your vehicle may be equipped with a Tire
Pressure Information System (TPIS).
The Tire Pressure Information System (TPIS)
uses wireless technology with wheel rim
mounted electronic sensors to transmit tire
pressure levels. Sensors mounted to each
wheel as part of the valve stem transmit tire
pressure readings to the receiver module.
NOTE:
It is particularly important for you to check
the tire pressure in all of the tires on your
vehicle monthly and to maintain the proper
pressure.
The TPIS consists of the following compo-
nents:
• Receiver module
• Four TPM sensors (Single Rear Wheel[SRW] applications)
• Six TPM sensors (Dual Rear Wheel [DRW] applications)
• Pressure display in the instrument cluster display. The TPIS system will display all four (Single
Rear Wheel [SRW] applications) or six (Dual
Rear Wheel [DRW] applications) tire pressure
values in the instrument cluster display.
If a system fault is detected, the instrument
cluster will display a "SERVICE TPM SYS-
TEM" message for a minimum of five seconds
and then display dashes (- -) in place of the
pressure value to indicate which sensor is not
being received.
If the ignition switch is cycled, this sequence
will repeat, providing the system fault still
exists. If the system fault no longer exists, the
"SERVICE TPM SYSTEM" message will no
longer be displayed, and a pressure value will
display in place of the dashes. A system fault
can occur due to any of the following:
• Signal interference due to electronic de-
vices or driving next to facilities emitting
the same radio frequencies as the TPM
sensors.
• Installing aftermarket window tinting that contains materials that may block radio
wave signals.
• Accumulation of snow or ice around the wheels or wheel housings. • Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM
sensors.

OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
SAFETY
76

BeltAlert can be activated or deactivated by
your authorized dealer. FCA US LLC does not
recommend deactivating BeltAlert.
NOTE:
If BeltAlert has been deactivated and the
driver or outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) is unbuckled the Seat Belt Re-
minder Light will turn on and remain on until
the driver and outboard front seat passenger
seat belts are buckled.
Lap/Shoulder Belts
All seating positions except the Crew Cab
front center seating position have combina-
tion lap/shoulder belts.
The seat belt webbing retractor will lock only
during very sudden stops or collisions. This
feature allows the shoulder part of the seat
belt to move freely with you under normal
conditions. However, in a collision the seat
belt will lock and reduce your risk of striking
the inside of the vehicle or being thrown out
of the vehicle.
WARNING!
• Relying on the air bags alone could leadto more severe injuries in a collision. The
air bags work with your seat belt to
restrain you properly. In some collisions,
the air bags won’t deploy at all. Always
wear your seat belt even though you have
air bags.
• In a collision, you and your passengers
can suffer much greater injuries if you
are not properly buckled up. You can
strike the interior of your vehicle or other
passengers, or you can be thrown out of
the vehicle. Always be sure you and
others in your vehicle are buckled up
properly.
• It is dangerous to ride in a cargo area,
inside or outside of a vehicle. In a colli-
sion, people riding in these areas are
more likely to be seriously injured or
killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts.
WARNING!
• Be sure everyone in your vehicle is in aseat and using a seat belt properly. Oc-
cupants, including the driver, should al-
ways wear their seat belts whether or not
an air bag is also provided at their seat-
ing position to minimize the risk of se-
vere injury or death in the event of a
crash.
• Wearing your seat belt incorrectly could
make your injuries in a collision much
worse. You might suffer internal injuries,
or you could even slide out of the seat
belt. Follow these instructions to wear
your seat belt safely and to keep your
passengers safe, too.
• Two people should never be belted into a
single seat belt. People belted together
can crash into one another in a collision,
hurting one another badly. Never use a
lap/shoulder belt or a lap belt for more
than one person, no matter what their
size.

As a guide, if you are shorter than average,
you will prefer the shoulder belt anchorage in
a lower position, and if you are taller than
average, you will prefer the shoulder belt
anchorage in a higher position. After you
release the anchorage button, try to move it
up or down to make sure that it is locked in
position.NOTE:
The adjustable upper shoulder belt anchor-
age is equipped with an Easy Up feature. This
feature allows the shoulder belt anchorage to
be adjusted in the upward position without
pushing or squeezing the release button. To
verify the shoulder belt anchorage is latched,
pull downward on the shoulder belt anchor-
age until it is locked into position.
WARNING!
• Wearing your seat belt incorrectly could
make your injuries in a collision much
worse. You might suffer internal injuries,
or you could even slide out of the seat
belt. Follow these instructions to wear
your seat belt safely and to keep your
passengers safe, too.
• Position the shoulder belt across the
shoulder and chest with minimal, if any
slack so that it is comfortable and not
resting on your neck. The retractor will
withdraw any slack in the shoulder belt.
• Misadjustment of the seat belt could
reduce the effectiveness of the safety
belt in a crash.
First Row Center Seat Belt Operating
Instructions (Regular Cab Only)
The first row center seat belt (Regular Cab
only) features a seat belt with a mini-latch
plate and buckle, which allows the seat belt
to detach from the lower anchor when the
seat is folded. The latch plate and regular
latch plate can then be stored out of the way
in the seat for added convenience to open up
utilization of the storage areas behind the
front seats when the seat is not occupied.
Adjustable Anchorage
SAFETY

WARNING!
and the center of the occupant’s body is
LESS than 6 inches.
• Using a Seat Belt Extender when not
needed can increase the risk of serious
injury or death in a collision. Only use
the Seat Belt Extender when the lap belt
is not long enough and only use in the
recommended seating positions. Re-
move and store the Seat Belt Extender
when not needed.
Seat Belts And Pregnant Women
Seat belts must be worn by all occupants
including pregnant women: the risk of injury
in the event of an accident is reduced for the
mother and the unborn child if they are wear-
ing a seat belt.
Position the lap belt snug and low below the
abdomen and across the strong bones of the
hips. Place the shoulder belt across the chest
and away from the neck. Never place the
shoulder belt behind the back or under the
arm.
Seat Belt Pretensioner — If Equipped
The front seat belt system may be equipped
with pretensioning devices that are designed
to remove slack from the seat belt in the
event of a collision. These devices may im-
prove the performance of the seat belt by
removing slack from the seat belt early in a
collision. Pretensioners work for all size oc-
cupants, including those in child restraints.
NOTE:
These devices are not a substitute for proper
seat belt placement by the occupant. The
seat belt still must be worn snugly and posi-
tioned properly. The pretensioners are triggered by the Occu-
pant Restraint Controller (ORC). Like the air
bags, the pretensioners are single use items.
A deployed pretensioner or a deployed air bag
must be replaced immediately.
Energy Management Feature — If Equipped
The front seat belt system may be equipped
with an Energy Management feature that may
help further reduce the risk of injury in the
event of a collision. The seat belt system has
a retractor assembly that is designed to re-
lease webbing in a controlled manner.
Switchable Automatic Locking Retractors
(ALR)
The seat belts in the passenger seating posi-
tions are equipped with a Switchable Auto-
matic Locking Retractor (ALR) which is used
to secure a child restraint system. For addi-
tional information, refer to “Installing Child
Restraints Using The Vehicle Seat Belt” un-
der the “Child Restraints” section of this
manual. The figure below illustrates the lock-
ing feature for each seating position.
Pregnant Women And Seat Belts

If the passenger seating position is equipped
with an ALR and is being used for normal
usage, only pull the seat belt webbing out far
enough to comfortably wrap around the occu-
pant’s mid-section so as to not activate the
ALR. If the ALR is activated, you will hear a
clicking sound as the seat belt retracts. Allow
the webbing to retract completely in this case
and then carefully pull out only the amount ofwebbing necessary to comfortably wrap
around the occupant’s mid-section. Slide the
latch plate into the buckle until you hear a
"click."
In Automatic Locking Mode, the shoulder
belt is automatically pre-locked. The seat
belt will still retract to remove any slack in
the shoulder belt. Use the Automatic Locking
Mode anytime a child restraint is installed in
a seating position that has a seat belt with
this feature. Children 12 years old and under
should always be properly restrained in a
vehicle with a rear seat.
WARNING!
• Never place a rear-facing child restraint
in front of an air bag. A deploying pas-
senger front air bag can cause death or
serious injury to a child 12 years or
younger, including a child in a rear-
facing child restraint.
• Only use a rear-facing child restraint in a
vehicle with a rear seat.

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:
