218 SAFETY
• When FCW status is set to “Only Warning” prevents thesystem from providing limited active braking, or addi -
tional brake support if the driver is not braking adequately
in the event of a potential frontal collision.
• When FCW status is set to “Warning and Braking” this allows the system to warn the driver of a possible collision
with the vehicle in front using audible/visual warnings
and it applies autonomous braking.
• The system will retain the last setting selected by the driver after ignition shutdown.
FCW Braking Status And Sensitivity
The FCW sensitivity and Active Braking status are program -
mable through the Uconnect System. Refer to “Uconnect
Settings” in “Multimedia” in the Owner's Manual for further
information.
• Far
•When the sensitivity of FCW is set to the “Far” settingand the system status is “Warning and Braking”, this
allows the system to warn the driver of a possible more
distant collisions with the vehicle in front using
audible/visual warnings. • More cautious drivers that do not mind frequent warn
-
ings may prefer this setting.
• Medium •When the sensitivity of FCW is set to the “Medium”setting and the system status is “Warning and
Braking”, this allows the system to warn the driver of a
possible collision with the vehicle in front using
audible/visual warnings.
• Near •When the sensitivity of FCW is set to the “Near” settingand the system status is “Warning and Braking”, this
allows the system to warn the driver of a possible closer
collisions with the vehicle in front using audible/visual
warnings.
•This setting provides less reaction time than the “Far” and “Medium” settings, which allows for a more
dynamic driving experience.
•More dynamic or aggressive drivers that want to avoid frequent warnings may prefer this setting.
SAFETY 223
Example: 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 automat -
ically update, the graphic display in the instrument cluster
will return to it’s original color, and the “Tire Pressure Moni -
toring 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. NOTE:
When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the recom
-
mended cold placard pressure in order to turn the Tire Pres -
sure Monitoring Telltale Light off.
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 a "SERVICE
TPM SYSTEM" message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value to indi -
cate 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 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
TPM sensors.
4
224 SAFETY
• 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.
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 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 a “Tire Pressure
Temporarily Unavailable” message in place of the tire pres -
sure 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 Moni -
toring 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 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 addi -
tion, 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 TPM Telltale Light will flash on
and off for 75 seconds and then remain on solid. In addi -
tion, 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.
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.

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.

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 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.
