Forward Collision Warning (FCW) With Mitigation — If
Equipped
The Forward Collision Warning (FCW) with Mitigation
system provides the driver with audible warnings, visual
warnings (within the instrument cluster display), and may
apply a brake jerk to warn the driver when it detects a poten -
tial frontal collision. The warnings and limited braking are
intended to provide the driver with enough time to react,
avoid or mitigate the potential collision. NOTE:
FCW monitors the information from the forward looking
sensors as well as the Electronic Brake Controller (EBC), to
calculate the probability of a forward collision. When the
system determines that a forward collision is probable, the
driver will be provided with audible and visual warnings as
well as a possible brake jerk warning.
If the driver does not take action based upon these progres
-
sive warnings, then the system will provide a limited level of
active braking to help slow the vehicle and mitigate the
potential forward collision. If the driver reacts to the warn -
ings by braking and the system determines that the driver
intends to avoid the collision by braking but has not applied
sufficient brake force, the system will compensate and
provide additional brake force as required.
If a FCW with Mitigation event begins at a speed below
32 mph (52 km/h), the system may provide the maximum braking possible to mitigate the potential forward collision.
If the Forward Collision Warning with Mitigation event
stops the vehicle completely, the system will hold the vehicle
at standstill for two seconds and then release the brakes.

224 SAFETY
Turning FCW On or Off
The FCW button is located in the Uconnect display in the
control settings. Refer to “Uconnect Settings” in “Multi-
media” for further information.
• To turn the FCW system on, press the forward collision button once to turn the system on.
• To turn the FCW system off, press the forward collision button once to turn the system off.
NOTE:
• When the FCW is “on”, this allows the system to warn the driver of a possible collision with the vehicle in front.
• When the FCW is “off”, this prevents the system from warning the driver of a possible collision with the vehicle
in front. If the FCW is set to “off”, “FCW OFF" will be
displayed in the instrument cluster display.
• When FCW status is set to “Only Warning”, this prevents the system 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” for further information.
• Far
• When the sensitivity of FCW is set to the “Far” settingand the system status is “Only Warning “, 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.
2020_DT_1500_OM_US.book Page 224

SAFETY 225
• Medium• When the sensitivity of FCW is set to the “Medium”setting and the system status is “Only Warning”, this
allows the system to warn the driver of a possible colli -
sion 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 “Only Warning”, this allows
the system to warn the driver of a possible closer colli -
sions 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. FCW Limited Warning
If the instrument cluster displays “ACC/FCW Limited Func
-
tionality” or “ACC/FCW Limited Functionality Clean Front
Windshield” momentarily, there may be a condition that
limits FCW functionality. Although the vehicle is still drive -
able under normal conditions, the active braking may not be
fully available. Once the condition that limited the system
performance is no longer present, the system will return to
its full performance state. If the problem persists, see an
authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster displays:
• ACC/FCW Unavailable Service Required
• Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. Although the
vehicle is still drivable under normal conditions, have the
system checked by an authorized dealer.

Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
NOTE:
The 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 pres -
sure values of each tire with the low tire pressure values in a
different color, or the Uconnect radio will display a TPMS
message, when this occurs you must increase the tire pres -
sure to the recommended cold placard pressure in order for
the TPMS Warning Light to turn off.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
after the vehicle has not been driven for at least three hours,
or driven less than 1 mile (1.6 km) after a three hour period.
The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire sidewall.
Refer to “Tires” in “Servicing And Maintenance” for infor -mation on how to properly inflate the vehicle’s tires. The tire
pressure will also increase as the vehicle is driven - this is
normal and there should be no adjustment for this increased
pressure.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low tire pres
-
sure as long as the condition exists, and will not turn off until
the tire pressure is at or above the recommended cold
placard pressure. Once the low TPMS Warning Light illumi -
nates, increase the tire pressure to the recommended cold
placard pressure in order for the TPMS Warning Light to
turn off. The system will automatically update and the TPMS
Warning Light will turn off once the system receives the
updated tire pressures. 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.

SAFETY 229
• The TPMS is not a substitute for proper tire maintenance,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 illumi -
nation of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.
Tire Pressure Monitor Display 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 System Warning Light

Tire Pressure Monitoring Low Pressure WarningsThe “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 automat
-
ically update, the graphic display in the instrument cluster
will return to it’s original color, and the “Tire Pressure Moni -
toring 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 recom -
mended cold placard pressure in order to turn the Tire Pres -
sure Monitoring System Warning Light off.
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.

2020_DT_1500_OM_US.book Page 230

SAFETY 231
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 drivingnext to facilities emitting the same radio frequencies as the
Tire Pressure Monitor (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

A system fault may occur due to an incorrect TPM sensor loca -
tion condition. When a system fault occurs due to an incorrect
TPM 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 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 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 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 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.
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 Fill
Alert 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 a positive increase in tire
pressure is detected by the TPM system while inflating the
tire. The ignition must be in the RUN mode, with the trans -
mission in PARK (P).
NOTE:
It is not required to have the engine running to enter Tire Fill
Alert mode.
