warning Ram 4500 Chassis Cab 2018 Owner's Guide

• 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.

Occupant Restraint Systems
Features
• Seat Belt Systems
• Supplemental Restraint Systems (SRS) AirBags
• 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 your autho-
rized 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 a vehicle with a
rear seat. 2. 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 (refer to “Child Restraints”
in this section for further information).
3. Children that are not big enough to wear the vehicle seat belt properly (refer to
“Child Restraints” in this section for fur-
ther information) should be secured in a
vehicle with a rear seat in child restraints
or belt-positioning booster seats. Older
children who do not use child restraints or
belt-positioning booster seats should ride
properly buckled up in a vehicle with a
rear seat.
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 deploy-
ment occurs, the side air bags will inflate
forcefully into the space between occu-
pants and the door and occupants could
be injured.
9. If the air bag system in this vehicle needs to be modified to accommodate a dis-
abled person, refer to the “Customer As-
sistance” section for customer service
contact information.
WARNING!
• Never place a rear-facing child restraintin 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.

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
Belt Alert feature is active whenever the igni-
tion switch is in the START or ON/RUN posi-
tion. Initial Indication
If the driver is unbuckled when the ignition
switch is first in the START or ON/RUN posi-
tion, 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 posi-
tion the Seat Belt Reminder Light will turn on
and remain on until both outboard front seat
belts are buckled. The outboard front passen-
ger seat BeltAlert is not active when an out-
board 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 out-
board 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 passen-
ger 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.
SAFETY
78

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.
79

WARNING!
• A lap belt worn too high can increase therisk 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 ve-
hicle, take it to your 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, increas-
ing the possibility of injury. Wear your
seat belt snugly.
WARNING!
• A seat belt that is worn under your arm isdangerous. Your body could strike the
inside surfaces of the vehicle in a colli-
sion, 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 re-
placed immediately. Do not disassemble
or modify the seat belt system. Seat belt
assemblies must be replaced after a
collision.
Lap/Shoulder Belt Operating Instructions
1. Enter the vehicle and close the door. Sit
back and adjust the seat.
2. The seat belt latch plate is above the back of the front seat, and next to your arm in
the rear seat (for vehicles equipped with a
rear seat). Grasp the latch plate and pull
out the seat belt. Slide the latch plate up
the webbing as far as necessary to allow
the seat belt to go around your lap.
Pulling Out The Latch Plate
SAFETY
80

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
82

10. To disengage the mini-latch plate fromthe mini-buckle for storage, insert the
regular latch plate into the center red
slot on the mini-buckle. The seat belt
will automatically retract to its stowed
position. If necessary, slide the latch
plate down the webbing to allow the seat
belt to retract fully. Insert the mini-latch
plate and regular latch plate into its
stowed position.WARNING!
• If the mini-latch plate and mini-buckleare 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 reat-
tach the mini-latch plate and mini-
buckle.
First Row Center Lap Belt Operating Instruc-
tions — 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 comfort-
able.
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, your
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!
• 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

SAFETY
84

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.
