2018 Ram 4500 Chassis Cab warning light

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.
• Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-
inflation 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 under-inflation has not reached the level
to trigger illumination of the TPM Telltale Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.Premium System
The Tire Pressure Monitor 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 sensors
• Various tire pressure monitoring system messages,
which display in the instrument cluster
• Tire pressure monitoring telltale light
178 SAFETY

Tire Pressure Monitoring Low Pressure WarningsThe “Tire Pressure Monitoring Telltale 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. 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 XXmessage. Once the
system receives the updated tire pressures, the system will
automatically update, the graphic display in the instru-
ment cluster will return to it’s original color, and the “Tire
Pressure Monitoring Telltale 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.

Service TPMS Warning
If a system fault is detected, the “Tire Pressure Monitoring
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 aSERVICE
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 Telltale Light”
will no longer flash, and the SERVICE TPM SYSTEMmessage 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 TPM sensors.
• Installing aftermarket window tinting that contains ma-
terials 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 system 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 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 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 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.
• After driving the vehicle for up to 20 minutes 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 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 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.

ger (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 unbuck-
led (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 buck-
led 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 your autho-
rized dealer. FCA US LLC does not recommend deactivat-
ing 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.

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) moni-
tors the internal circuits and interconnecting wiring asso-
ciated 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 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 Warn-
ing 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 diagnos-
tics 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 intermittently 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.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 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 compartment. The words “SRS
AIRBAG” or “AIRBAG” are embossed on the air bag
covers.

front air bags then quickly deflate while helping to restrain
the driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and front passenger, and position the front occu-
pants for improved interaction with the front air bags.
WARNING!
•Do not drill, cut, or tamper with the knee impact
bolsters in any way.
• Do not mount any accessories to the knee impact
