2020 Ram 3500 warning

162SAFETY
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” 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”
prevents the system from providing limited
active braking, or additional 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 FCW system state is defaulted to “Full
On” from one ignition cycle to the next. If the
system is turned off, it will reset to “Full On”
when the vehicle is restarted.
FCW Braking Status And Sensitivity
The FCW sensitivity and Active Braking status
are programmable through the Uconnect
System. Refer to “Uconnect Settings” in
“Multimedia” for further information.
Far
When the sensitivity of FCW is set to the
“Far” setting and the system status is
“Warning and Braking”, this allows the
system to warn the driver of a possible
more distant collision with the vehicle in
front using audible/visual warnings.
More cautious drivers that do not mind
frequent warnings 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” setting and the system status is
“Warning and Braking”, this allows the
system to warn the driver of a possible
closer collision 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 Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield”
momentarily, there may be a condition that
limits FCW functionality. Although the vehicle is
still drivable 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.

20_DJD2_OM_EN_USC_t.book Page 162

SAFETY163
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 recommended 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 pres -
sure values in a different color, or the Uconnect
radio will display a TPMS message, when this
occurs you must increase the tire pressure 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
4

20_DJD2_OM_EN_USC_t.book Page 163

164SAFETY
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 information 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 pressure 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
illuminates, you must 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.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off.

For example, your vehicle may have a
recommended cold (parked for more than three
hours) placard pressure of 30 psi (207 kPa). If
the ambient temperature is 68°F (20°C) and the
measured tire pressure is 27 psi (186 kPa), a
temperature drop to 20°F (-7°C) will decrease
the tire pressure to approximately 23 psi
(158 kPa). This tire pressure is sufficiently low
enough to turn on the TPMS Warning Light.
Driving the vehicle may cause the tire pressure to
rise to approximately 27 psi (186 kPa), but the
TPMS Warning Light will still be on. In this
situation, the TPMS Warning Light will turn off
only after the tires are inflated to the vehicle’s
recommended cold placard pressure value.
CAUTION!
The TPMS has been optimized for the orig -
inal equipment tires and wheels. TPMS
pressures and warning have been estab -
lished for the tire size equipped on your
vehicle. Undesirable system operation or
sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. Aftermarket
wheels can cause sensor damage.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. After
using an aftermarket tire sealant it is
recommended that you take your vehicle to
an authorized dealership to have your
sensor function checked.
After inspecting or adjusting the tire pres -
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could
damage the TPMS sensor.

20_DJD2_OM_EN_USC_t.book Page 164

SAFETY165
NOTE:
The TPMS is not intended to replace normal
tire care and maintenance or to provide
warning of a tire failure or condition.
If your vehicle is not equipped with the Tire
Fill Alert feature 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
maintenance, and it is the driver’s responsi -
bility 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 TPMS Warning
Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor the
actual tire pressure in the tire.
Example: Tire Pressure Monitoring Display

The Tire Pressure Monitoring 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
Warnings
The “Tire Pressure Monitoring
Warning Light” will illuminate in the
instrument cluster 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.

Example: Low Tire Pressure Display
4

20_DJD2_OM_EN_USC_t.book Page 165

166SAFETY
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 automatically
update, the graphic display in the instrument
cluster will return to its 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.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the Tire Pressure Moni -
toring Warning Light off.
Service TPMS Warning
If a system fault is detected, the “Tire Pressure
Monitoring 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 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 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 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 system
fault occurs due to an incorrect TPM sensor
location, the “Tire Pressure Monitoring 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
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.

20_DJD2_OM_EN_USC_t.book Page 166

SAFETY167
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 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 TPM Warning
Light will flash on and off for 75 seconds and
then remain on solid. In addition, the instru -
ment 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 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 pres -
sure 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 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.
Trailer Tire Pressure Monitoring System
(TTPMS) — If Equipped
The Trailer Tire Pressure Monitoring System
(TTPMS) is a feature that displays the trailer tire
pressure values and warn the driver of a low tire
pressure event based on the drivers set target
tire pressure value, through TTPMS settings
found in the radio.
The TTPMS monitors the pressure of each tire
and warns the driver through the instrument
cluster, when either a low tire pressure
condition falls below 25% of the drivers set
pressure or if a system malfunction occurs. The
instrument cluster 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 system can support
up to 12 trailer tires per configured trailer on up
to four configurable trailers. Refer to “Uconnect
Settings” in “Multimedia” for further
information.

Trailer Tire Pressure Monitoring System

Trailer Tire Pressure Sensor Pairing
In order use this feature, the provided tire
pressure sensors must be installed in the
desired trailer tires and the sensors must be
paired to the truck. If the target trailer requires
more than the provided four sensors, additional
sensors can be purchased at an authorized
Ram dealership.

20_DJD2_OM_EN_USC_t.book Page 167

168SAFETY
With the sensors installed and the trailer near
or connected to your Ram truck, initiate the
pairing process by entering the settings menu in
the radio and select trailer. Refer to “Uconnect
Settings” in “Multimedia” for further
information. Select the desired trailer profile to
pair to, open the “Tire Pressure” menu, and hit
“Setup All Tires.”
NOTE:
The vehicle may not be driven until the pairing
process is complete.

Trailer Tire Pressure Settings Trailer Tire Pressure Pairing

Follow the on screen prompts to select the
number of axles (1 - 3), the number of trailer
tires (2, 4, 6, 8, or 12), and the set trailer tire
pressure. The range is selectable anywhere
between 25-125 PSI (172-862 kPa).
Once PSI (kPa) is programmed, the pairing
screen appears. Tire sensors must be paired in
order shown. Starting with Tire 1, deflate tire by
5 PSI (34 kPa) and wait for a horn chirp. It may
take up to 3 minutes for the chirp to occur,
indicating that the sensor has paired. Repeat
process on each tire, in order, until complete.
Do not exit the pairing screen until process is
complete. If pairing was unsuccessful, a double
horn chirp will sound, and a prompt on the touchscreen will allow you to retry the
procedure; “Retry” will only appear when setup
fails. Each tire must be successfully paired
during a single pairing process to receive the
success screen.
NOTE:
If the pairing process times out after three
minutes of no communication with a sensor, a
double horn chip will occur indicating the
pairing has failed and a message will display on
the radio indicating the process was unsuc
-
cessful. Under certain circumstances, the
double horn chirp may continue to happen
every three minutes indicating the failed
pairing. If this happens, the horn chirping may
be canceled by cycling the ignition button off
and then back to run position.
Tire Pressure Monitoring Low Pressure
Warnings
When a tire pressure low in one or more of the
active road tires is detected, the instrument
cluster will display a message stating “Trailer
Tire Pressure Low”. The instrument cluster will
then display the TTPMS graphic showing the
pressure values of each tire with the low tire
pressure values in a different color.

20_DJD2_OM_EN_USC_t.book Page 168

SAFETY169
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 at the top of the TTPMS instrument
cluster graphic. Once the tire(s) are inflated, the
system will automatically update the graphic
display in the instrument cluster, returning 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 instrument
cluster will display a “Trailer Tire Pressure
System Service Required” message for a
minimum of five seconds.
Once the system fault is corrected the "Trailer
Tire Pressure System Service Required"
message will no longer be displayed. 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 trailer tire pressure
information. Trailer Tire Pressure System Not Configured
A “Trailer Tire Pressure System Not Configured”
message will be displayed in the Instrument
Cluster on the TTPM instrument cluster graphic
when a trailer number is selected that has not
had trailer tire pressure sensors paired. To
correct this condition, see “Trailer Tire Pressure
Sensor Pairing” in “Multimedia”.
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 not
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 Fill Alert system.
The Tire Fill Alert feature cannot be entered if
an existing TPMS fault is set to “active” or if
the system is in deactivation mode (if
equipped).
The system will be activated when the system
detects a increase of tire pressure, while filling
the fire. 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.
