SAFETY 225

• For each subsequent ignition switch cycle, a chime willsound, 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 rein -
stall it on the vehicle in place of the non matching full size
spare or compact spare, the TPMS will update automati -
cally. 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.
Trailer Tire Pressure Monitoring System (TTPMS)
The Trailer Tire Pressure Monitoring System (TTPMS) is a
feature that will display the trailer tire pressure values and
warn the driver of a low trailer tire pressure, based on the
drivers set target tire pressure value, through the Instrument
Cluster (IC). The TTPMS monitors the pressure of each tire and warns the
driver, through the IC, when either a low tire pressure condi
-
tion or a TPM sensor or system malfunction condition exists.
The IC will display the actual tire pressure or dashes for each
of the trailer tires in the correct trailer position, based on
trailer configuration.
The TTPMS consist of the following components:
• Trailer Receiver Module
• Trailer Interface Module
• Two to twelve tire pressure monitoring sensors depending on trailer configuration
The TTPMS is configured though the trailer settings menu in
the Uconnect system by selecting the desired trailer number
(up to four trailers can be configured), the number of axles (1
- 3), the number of trailer tires (2, 4, 6, 8, or 12), and the set
trailer tire pressure. Refer to “Uconnect Settings” in “Multi -
media” for further information.

226 SAFETY
Tire Pressure Monitoring Low Pressure Warnings
When a tire pressure low in one or more of the active road
tires is detected a chime will sound. In addition, the instru-
ment 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 XXX” message will also be
displayed.
NOTE:
"XXX" = TPM trailer tire target pressure value programmed
by the customer
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 in
the “Inflate to XXX” message. Once the system receives the
updated tire pressures, the system will automatically update
the graphic display in the instrument cluster will return 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 system fault will sound a
chime and the instrument cluster will display a “Trailer Tire
Pressure System Service Required” 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.
Once the system fault is corrected the "Trailer Tire Pressure
System Service Required" message will no longer be
displayed and the dashes will be replaced by pressure
values. 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.
Trailer Tire Pressure System Not Configured
A “Trailer Tire Pressure System Not Configured” message
will be displayed in the Instrument Cluster when a trailer
number is selected that does not have configuration values
entered for the (Number of Tires, Number of Axles, SET
Target Tire Pressure, trailer TPM sensor ID's).
To correct this condition the (Number of Tires, Number of
Axles, and SET Target Tire Pressure) values must be entered
in the radio for the trailer number selected. The trailer
sensors must also be paired to the trailer. Refer to the “Ucon -
nect Settings” in “Multimedia” for further information.

SAFETY 227
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
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
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 FillAlert 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 pressure. The ignition must be in the
RUN mode, with the transmission in PARK (P).
NOTE:
It is not required to have the engine running to enter Tire Fill
Alert mode.
The hazard lamps will come on to confirm the vehicle is in
Tire Fill Alert mode.
When Tire Fill Alert Mode is entered, the tire pressure
display screen will be displayed in the instrument cluster.
Operation:
• The horn will chirp to let the user know when to stop filling the tire, when it reaches recommended pressure.
• The horn will chirp three times if the tire is over filled and will continue to chirp every five seconds if the user
continues to inflate the tire.
4

228 SAFETY
• The horn will chirp once again when enough air is let outto reach proper inflation level.
• The horn will also chirp three times if the tire is then under-inflated and will continue to chirp every five
seconds if the user continues to deflate the tire.
Selectable Tire Fill Alert (STFA)
The Selectable Tire Fill Alert (STFA) system is an optional
feature that is included as part of the normal Tire Fill Alert
system. The system is designed to allow the customer to
select a pressure to inflate or deflate the vehicle's front and
rear axle tires to and to provide feedback to the customer
while inflating or deflating the vehicle's tires.
In the Selectable Tire Fill Alert customer settings menu in the
radio, the customer will be able to select a pressure setting
for both the front and rear axle tire pressures by scrolling
through a pressure range from XX to 15 psi in 1 psi incre -
ments for each axle setting. XX = the vehicle’s cold placard
pressure values for the front and rear axles as shown on the
vehicle placard pressure label.
The customer may also store the pressure values chosen for
each axle in the radio as a preset pressure. The customer will
be allowed to store up to two sets of preset values in the radio
for the front and rear axle pressure values. Once the customer selects the tire pressures for the front and
rear axles that they want to inflate or deflate to, they can
begin inflating or deflating one tire at a time.
NOTE:
The STFA system will only support inflating or deflating one
tire at a time.
The system will be activated when the TPM receiver module
detects a change in tire pressure. The ignition must be in the
RUN mode, with the transmission in PARK (P).
The hazard lamps will come on to confirm the vehicle is in
Tire Fill Alert mode.
When Tire Fill Alert Mode is entered, the tire pressure
display screen will be displayed in the instrument cluster.
Operation:
• The horn will chirp once when the selected pressure is
reached to let the user know when to stop inflating or
deflating the tire.
• The horn will chirp three times if the tire is over inflated or over deflated and will continue to chirp every five seconds
if the user continues to inflate or deflate the tire.
• The horn will chirp once again when enough air is added or removed to reach proper selected pressure level.

SAFETY 229
Tire Pressure Information System (TPIS) 3500 Series
Trucks
Your vehicle may be equipped with a Tire Pressure Informa-
tion 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 components:
• Receiver module
• Four TPM sensors (Single Rear Wheel (SRW) applications)
• Six TPM sensors (Dual Rear Wheel (DRW) applications)
• Pressure display in the instrument cluster
The TPIS system will display all four (Single Rear Wheel
(SRW) applications) or six (Dual Rear Wheel (DRW) applica -
tions) tire pressure values in the instrument cluster display. If a system fault is detected, 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 "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 devices or driving
next to facilities emitting the same radio frequencies as the
TPM sensors.
• Installing aftermarket window tinting that contains mate -
rials 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.

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 colli-
sion. 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 Compo -
nents:
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 • Front and Side Impact Sensors — If Equipped
• Seat Belt Pretensioners
• Seat Track Position Sensors
Air Bag Warning Light
The ORC monitors the readiness of the elec -
tronic 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 instru-
ment 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.
4

246 SAFETY
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 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 thefour 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 Bag/Knee Bolster Locations Driver And Passenger Front Air Bag Features
2500 Series Truck
The Advanced Front Air Bag system has multistage driver
and front passenger air bags. This system provides output
appropriate to the severity and type of collision as deter
-
mined by the Occupant Restraint Controller (ORC), which
may receive information from the front impact sensors (if
equipped) or other system components.
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.
