2023 RAM 1500 warning

278SAFETY
NOTE:
The TPMS is not intended to replace normal tire care
and maintenance or to provide warning of a tire failure
or condition.
 The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure, unless your vehicle
is equipped with a Tire Fill Alert (TFA) system.
 Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla -
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
 The TPMS is not a substitute for proper tire mainte -
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if underinflation has not reached the level
to trigger illumination of the TPMS Warning Light.
 Seasonal temperature changes will affect tire pres -
sure, and the TPMS will monitor the actual tire pres -
sure in the tire.

Tire Pressure Monitoring System Display

The Tire Pressure Monitoring System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor 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 TPMS consists of the following components:
 Receiver module
 Four Tire Pressure Monitoring System sensors
 Various Tire Pressure Monitoring System messages,
which display in the instrument cluster
 Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System (TPMS)
Warning Light will illuminate in the instrument
cluster and a chime will sound when tire
pressure is low in one or more of the four active
road tires. In addition, the instrument cluster will display a
graphic showing the pressure values of each tire with the
low tire pressure values in a different color. An "Inflate to
XX" message will also be displayed.

Low Tire Pressure Display

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 instrument cluster
graphic) to the vehicle’s recommended cold placard
pressure inflation value as shown in the "Inflate to XX"
message. Once the system receives the updated tire
pressures, the system will automatically update, the
graphic display in the instrument cluster will return to its
original color, and the Tire Pressure Monitoring System
Warning Light will turn off. 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.
NOTE:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring System Warning Light off.

SAFETY279
Service TPMS Warning
If a system fault is detected, the Tire Pressure Monitoring
System (TPMS) Warning 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 "SERVICE TPM SYSTEM" 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 Tire Pressure Monitoring System
Warning Light will no longer flash, and the "SERVICE TPM
SYSTEM" message will no longer display, 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 devices or driving
next to facilities emitting the same radio frequencies
as the Tire Pressure Monitoring System 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 TPMS sensors
A system fault may occur due to an incorrect TPMS sensor
location condition. When a system fault occurs due to an
incorrect TPMS sensor location, the Tire Pressure
Monitoring System (TPMS) Warning 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
System Warning Light” will no longer flash and the tire
pressure 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 compact spare tire
does not have a TPMS 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 Tire Pressure
Monitoring System (TPMS) Warning Light and a
“LOW TIRE” message will remain on and a chime will
sound. In addition, the graphic in the instrument
cluster will still display a pressure value in a different
color and an “Inflate to XX” message.
 After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the Tire Pressure Monitoring
System (TPMS) Warning 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 Tire Pressure Monitoring System (TPMS)
Warning Light will flash on and off for 75 seconds and
then remain on solid, and 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.
 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 Tire Pressure Monitoring
System (TPMS) Warning 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 Fill Alert
This feature notifies the user when the placard tire
pressure is attained while inflating or deflating the tire.
You may choose to disable or enable the Tire Fill Alert
feature through use of the Uconnect 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 TPMS fault is set to “active” or if the system is
in deactivation mode (if equipped).

Trailer Tire Pressure Pairing

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 procedure; “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 chip 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 indi -
cating the failed pairing. If this happens, the horn chirping
may be canceled by cycling the ignition button OFF and
then back to RUN position.
Tire Pressure Monitoring System Low Pressure 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.
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 instrument 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 its 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 TTPMS
instrument cluster graphic when a trailer number is
selected that has not had trailer tire pressure sensors
paired. To correct this condition, see
Úpage 191.
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
TTPMS 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 TTPMS module.
To correct this condition, the correct trailer number must
be selected in the radio

OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your vehicle
are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
 Seat Belt Systems
 Supplemental Restraint Systems (SRS) Air Bags
 Child Restraints
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.
IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in this
section. It tells you how to use your restraint system
properly, to keep you and your passengers as safe as
possible.
Here are some simple steps you can take to minimize the
risk of harm from a deploying air bag:

1. Children 12 years old and under should always ride buckled up in the rear seat of a vehicle with
a rear seat.

2. A child who is not big enough to wear the vehicle seat belt properly must be secured in the appropriate child
restraint or belt-positioning booster seat in a rear
seating position
Úpage 298. 3. If a child from 2 to 12 years old (not in a rear-facing
child restraint) must ride in the front passenger seat,
move the seat as far back as possible and use the
proper child restraint
Úpage 298.
4. Never allow children to slide the shoulder belt behind them or under their arm.
5. You should read the instructions provided with your child restraint to make sure that you are using it
properly.
6. All occupants should always wear their lap and shoulder belts properly.
7. The driver and front passenger seats should be moved back as far as practical to allow the front air
bags room to inflate.
8. Do not lean against the door or window. If your vehicle has side air bags, and deployment occurs, the side air
bags will inflate forcefully into the space between
occupants and the door and occupants could be
injured.
9. If the air bag system in this vehicle needs to be modified to accommodate a disabled person, see
Úpage 398 for customer service contact
information.
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.
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.

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.
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 recommended 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 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
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 in your vehicle are equipped with 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 lead to more
severe injuries in a collision. The air bags work with
your seat belt to restrain you properly. In some colli -
sions, 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 collision, people riding in
these areas are more likely to be seriously injured
or killed.

284SAFETY
(Continued)

Do not allow people to ride in any area of your vehicle
that is not equipped with seats and seat belts.
 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 posi -
tion 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!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 inju -
ries. Always buckle your seat belt into the buckle
nearest you.
 A seat belt that is too loose will not protect you prop -
erly. In a sudden stop, you could move too far
forward, increasing the possibility 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 injuries. 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 imme -
diately. Do not disassemble or modify the seat belt
system. If your vehicle is involved in a collision, or if
you have questions regarding seat belt or retractor
conditions, take your vehicle to an authorized FCA
dealer or authorized FCA Certified Collision Care
Program facility for inspection.

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 position.
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.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 authorized 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!
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 comfort -
able 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.
 Always make all seat belt height adjustments when
the vehicle is stationary.WARNING!
ONLY use a Seat Belt Extender if it is physically
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 occu -
pant’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. Remove and store
the Seat Belt Extender when not needed.

23_DT_OM_EN_USC_t.book Page 286

288SAFETY
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 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. Grab the shoulder portion and pull downward 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.
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 interconnecting wiring
associated with the electrical Air Bag System
Components. Your vehicle may be equipped with the
following Air Bag System Components:
