Trailer Tire Pressure Sensor Pairing
In order use this feature, the provided tire pres -
sure sensors must be installed in the desired
trailer tires and the sensors must be paired to
the truck. If the target trailer requires more than
the provided four sensors, additional sensors
can be purchased at an authorized Ram dealer -
ship.
With the sensors installed and the trailer near
or connected to your Ram truck, initiate the
pairing process by entering the settings menu in
the radio and select trailer. Refer to “Uconnect
Settings” in “Multimedia” for further informa -
tion. Select the desired trailer profile to pair to,
open the “Tire Pressure” menu, and hit “Setup
All Tires.” Follow the on screen prompts to select the
number of axles (1 - 3), the number of trailer
tires (2, 4, 6, 8, or 12), and the set trailer tire
pressure. The range is selectable anywhere
between 25-125 PSI (172-862 kPa).
Once PSI (kPa) is programmed, the pairing
screen appears. Tire sensors must be paired in
order shown. Starting with Tire 1, deflate tire by
5 PSI (34 kPa) and wait for a horn chirp. It may
take up to three minutes for the chirp to occur,
indicating that the sensor has paired. Repeat
process on each tire, in order, until complete.
Do not exit the pairing screen until process is
complete. If pairing was unsuccessful, a double
horn chirp will sound, and a prompt on the touchscreen will allow you to retry the proce
-
dure; “Retry” will only appear when setup fails.
Each tire must be successfully paired during a
single pairing process to receive the success
screen.
NOTE:
If the pairing process times out after three
minutes of no communication with a sensor, a
double horn chirp will occur indicating the
pairing has failed and a message will display on
the radio indicating the process was unsuc -
cessful. Under certain circumstances, the
double horn chirp may continue to happen
every three minutes indicating the failed
pairing. If this happens, the horn chirping may
be canceled by cycling the ignition button OFF
and then back to ON/RUN position.
Tire Pres sure Monitoring Lo w Pre ssure
Warnings
When a tire pressure low in one or more of the
active road tires is detected, the instrument
cluster will display a message stating “Trailer
Tire Pressure Low”. The instrument cluster will
then display the TTPMS graphic showing the
pressure values of each tire with the low tire
pressure values in a different color.

138SAFETY
Should this occur, you should stop as soon as
possible and inflate the tires with a low pressure
condition (those in a different color in the instru -
ment cluster graphic) to the customer
programmed target tire pressure value as
shown at the top of the TTPMS instrument
cluster graphic. Once the tire(s) are inflated, the
system will automatically update the graphic
display in the instrument cluster, returning to
it’s original color. The vehicle may need to be
driven for up to 10 minutes above 15 mph
(24 km/h) in order for the TTPMS to receive the
updated information.
Service TTPMS Warning
If a system fault is detected, the instrument
cluster will display a “Trailer Tire Pressure
System Service Required” message for a
minimum of five seconds.
Once the system fault is corrected the "Trailer
Tire Pressure System Service Required"
message will no longer be displayed. The
vehicle may need to be driven for up to
10 minutes above 15 mph (24 km/h) in order
for the TTPMS to receive the trailer tire pressure
information. Trailer Tire Pressure System Not Configured
A “Trailer Tire Pressure System Not Configured”
message will be displayed in the Instrument
Cluster on the TTPM instrument cluster graphic
when a trailer number is selected that has not
had trailer tire pressure sensors paired. To
correct this condition, see “Trailer Tire Pressure
Sensor Pairing” in “Multimedia”.
Trailer Sensors Detected Do Not Match Active
Trailer
The “Trailer Sensors Detected Do Not Match
Active Trailer” message will be displayed in the
Instrument Cluster when the trailer sensors
being received by the TTPM module do not
match the trailer sensors paired to the current
trailer number selected. This message will be
displayed when the sensors being received
completely match the sensors paired to another
trailer number configured in the TTPM module.
To correct this condition, the correct trailer
number must be selected in the radio. Refer to
the “Uconnect Settings” in “Multimedia” for
further information.Tire Fill Alert — If Equipped
This feature notifies the user when the placard
tire pressure is attained while inflating or
deflating the tire.
The customer may choose to disable or enable
the Tire Fill Alert feature through use of the
customer settings in the radio.
NOTE:
Only one tire can be filled at a time when
using the Tire Fill Alert system.
The Tire Fill Alert feature cannot be entered if
an existing TPM system fault is set to “active”
or if the system is in deactivation mode (if
equipped).
The system will be activated when the TPM
receiver module detects a change in tire pres -
sure. The ignition must be in the RUN mode,
with the transmission in PARK (P).

Seat Belt Systems
Buckle up even though you are an excellent
driver, even on short trips. Someone on the road
may be a poor driver and could cause a collision
that includes you. This can happen far away
from home or on your own street. Research has shown that seat belts save lives,
and they can reduce the seriousness of injuries
in a collision. Some of the worst injuries happen
when people are thrown from the vehicle. Seat
belts reduce the possibility of ejection and the
risk of injury caused by striking the inside of the
vehicle. Everyone in a motor vehicle should be
belted at all times.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver And Passenger BeltAlert — If Equipped
BeltAlert is a feature intended to remind the
driver and outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) to buckle their seat belts. The
BeltAlert feature is active whenever the ignition
switch is in the START or ON/RUN position.
Initial Indication
If the driver is unbuckled when the ignition
switch is first in the START or ON/RUN position,
a chime will signal for a few seconds. If the
driver or outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition switch
is first in the START or ON/RUN position the Seat Belt Reminder Light will turn on and
remain on until both outboard front seat belts
are buckled. The outboard front passenger seat
BeltAlert is not active when an outboard front
passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated
when the vehicle is moving above a specified
vehicle speed range and the driver or outboard
front seat passenger is unbuckled (if equipped
with outboard front passenger seat BeltAlert)
(the outboard front passenger seat BeltAlert is
not active when the outboard front passenger
seat is unoccupied). The BeltAlert warning
sequence starts by blinking the Seat Belt
Reminder Light and sounding an intermittent
chime. Once the BeltAlert warning sequence
has completed, the Seat Belt Reminder Light
will remain on until the seat belts are buckled.
The BeltAlert warning sequence may repeat
based on vehicle speed until the driver and
occupied outboard front seat passenger seat
belts are buckled. The driver should instruct all
occupants to buckle their seat belts.
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
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.
Never install a rear-facing child restraint in
the front seat of a vehicle. Only use a
rear-facing child restraint in the rear seat. If
the vehicle does not have a rear seat, do
not transport a rear-facing child restraint in
that vehicle.

SAFETY143
(Continued)
Change Of Status
If the driver or outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) unbuckles their seat belt while the
vehicle is traveling, the BeltAlert warning
sequence will begin until the seat belts are
buckled again.
The outboard front passenger seat BeltAlert is
not active when the outboard front passenger
seat is unoccupied. BeltAlert may be triggered
when an animal or other items are placed on
the outboard front passenger seat or when the
seat is folded flat (if equipped). It is recom -
mended that pets be restrained in the rear seat
(if equipped) in pet harnesses or pet carriers
that are secured by seat belts, and cargo is
properly stowed.
BeltAlert can be activated or deactivated by an
authorized dealer. FCA US LLC does not recom -
mend 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 Reminder 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 combination 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 condi
-
tions. 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 lead to
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 inte -
rior 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 collision,
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.

144SAFETY
(Continued)
Be sure everyone in your vehicle is in a seat
and using a seat belt properly. Occupants,
including the driver, should always wear
their seat belts whether or not an air bag is
also provided at their seating position to
minimize the risk of severe 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.
WARNING! (Continued)WARNING!
A lap belt worn too high can increase the
risk of injury in a collision. The seat belt
forces won’t be at the strong hip and pelvic
bones, but across your abdomen. Always
wear the lap part of your seat belt as low as
possible and keep it snug.
A twisted seat belt may not protect you
properly. In a collision, it could even cut into
you. Be sure the seat belt is flat against
your body, without twists. If you can’t
straighten a seat belt in your vehicle, take it
to an authorized dealer immediately and
have it fixed.
A seat belt that is buckled into the wrong
buckle will not protect you properly. The lap
portion could ride too high on your body,
possibly causing internal injuries. Always
buckle your seat belt into the buckle
nearest you.
A seat belt that is too loose will not protect
you properly. In a sudden stop, you could
move too far forward, increasing the possi -
bility of injury. Wear your seat belt snugly.
A seat belt that is worn under your arm is
dangerous. Your body could strike the
inside surfaces of the vehicle in a collision,
increasing head and neck injury. A seat belt
worn under the arm can cause internal inju -
ries. Ribs aren’t as strong as shoulder
bones. Wear the seat belt over your
shoulder so that your strongest bones will
take the force in a collision.
A shoulder belt placed behind you will not
protect you from injury during a collision.
You are more likely to hit your head in a
collision if you do not wear your shoulder
belt. The lap and shoulder belt are meant to
be used together.
A frayed or torn seat belt could rip apart in
a collision and leave you with no protection.
Inspect the seat belt system periodically,
checking for cuts, frays, or loose parts.
Damaged parts must be replaced immedi-
ately. Do not disassemble or modify the
seat belt system. Seat belt assemblies
must be replaced after a collision.

Lap/Shoulder Belt Untwisting Procedure
Use the following procedure to untwist a twisted
lap/shoulder belt.

1. Position the latch plate as close as
possible to the anchor point.

2. At about 6 to 12 inches (15 to 30 cm) above the latch plate, grasp and twist the seat belt
webbing 180 degrees to create a fold that
begins immediately above the latch plate.
3. Slide the latch plate upward over the folded webbing. The folded webbing must enter
the slot at the top of the latch plate.
4. Continue to slide the latch plate up until it clears the folded webbing and the seat belt
is no longer twisted.
Adjustable Upper Shoulder Belt Anchorage
In the driver and outboard front passenger
seats, the top of the shoulder belt can be
adjusted upward or downward to position the
seat belt away from your neck. Push or squeeze
the anchorage button to release the anchorage,
and move it up or down to the position that
serves you best.
Adjustable Anchorage

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 posi -
tion.
NOTE:
The adjustable upper shoulder belt anchorage
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 anchorage
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 with -
draw any slack in the shoulder belt.
Misadjustment of the seat belt could
reduce the effectiveness of the safety belt
in a crash.
Always make all seat belt height adjust -
ments when the vehicle is stationary.

mini-latch plate and regular latch plate into
its stowed position.

Detaching Mini-Buckle With Seat Belt Tongue

First Row Center Lap Belt Operating
Instructions — If Equipped
The center seating position for the Crew Cab
front seat has a lap belt only. To buckle the lap
belt, slide the latch plate into the buckle until
you hear a "click." To lengthen the lap belt, tilt
the latch plate and pull.
To remove slack, pull the loose end of the
webbing. Wear the lap belt snug against the
hips. Sit back and upright in the seat, then
adjust the seat belt as tightly as is comfortable.
Seat Belt Extender
If a seat belt is not long enough to fit properly,
even when the webbing is fully extended and
the adjustable upper shoulder belt anchorage
(if equipped) is in its lowest position, an autho -
rized dealer can provide you with a Seat Belt
Extender. The Seat Belt Extender should be
used only if the existing seat belt is not long
enough. When the Seat Belt Extender is not
required for a different occupant, it must be
removed.
WARNING!
If the mini-latch plate and mini-buckle are
not properly connected when the seat belt
is used by an occupant, the seat belt will
not be able to provide proper restraint and
will increase the risk of injury in a collision.
When reattaching the mini-latch plate and
mini-buckle, ensure the seat belt webbing
is not twisted. If the webbing is twisted,
follow the preceding procedure to detach
the mini-latch plate and mini-buckle,
untwist the webbing, and reattach the
mini-latch plate and mini-buckle.
WARNING! (Continued)
WARNING!
ONLY use a Seat Belt Extender if it is physi -
cally required in order to properly fit the
original seat belt system. DO NOT USE the
Seat Belt Extender if, when worn, the
distance between the front edge of the
Seat Belt Extender buckle 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 recom -
mended seating positions. Remove and
store the Seat Belt Extender when not
needed.

Crew Cab Automatic Locking Retractor ( ALR)
Locations

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 occupant’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 care -
fully pull out only the amount of webbing neces -
sary 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 prop
-
erly restrained in the rear seat of a vehicle with
a rear seat.
How To Engage The Automatic Locking Mode

1. Buckle the combination lap and shoulder belt.

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 disengage
the Automatic Locking Mode and activate the
vehicle sensitive (emergency) locking mode.
ALR — Switchable Automatic Locking Retractor

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 an authorized
dealer.
The air bag system must be ready to protect you
in a collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and inter -
connecting wiring associated with the electrical
Air Bag System Components. 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 whenever the ignition switch
is in the START or 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 discon -
nected 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 illu-
minate 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 is designed to be maintenance
free, if any of the following occurs, have an
authorized dealer service the air bag system
immediately.
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 intermit
-
tently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant
Restraint Controller (ORC) may also be
disabled. In this condition the air bags may not
be ready to inflate for your protection. 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 supplement 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 compart-
ment. The words “SRS AIRBAG” or “AIRBAG” are
embossed on the air bag covers.
Front Air Bag/Knee Bolster Locations

Driver And Passenger Front Air Bag Features
The Advanced Front Air Bag system has multi
-
stage driver and front passenger air bags. This
system provides output appropriate to the
severity and type of collision as determined by
the Occupant Restraint Controller (ORC), which
may receive information from the front impact
sensors (if equipped) or other system compo -
nents.
The first stage inflator is triggered immediately
during an impact that requires air bag deploy -
ment. A low energy output is used in less severe
collisions. A higher energy output is used for
more severe collisions.
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.
1 — Driver And Passenger Front Air Bags
2 — Driver And Passenger Knee Impact Bolsters
WARNING!
Being too close to the steering wheel or
instrument panel during front air bag
deployment could cause serious injury,
including death. Air bags need room to
inflate. Sit back, comfortably extending
your arms to reach the steering wheel or
instrument panel.
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
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.
Never install a rear-facing child restraint in
the front seat of a vehicle. Only use a
rear-facing child restraint in the rear seat. If
the vehicle does not have a rear seat, do
not transport a rear-facing child restraint in
that vehicle.
