The ESC Activation/Malfunction Indicator Light starts to
flash as soon as the tires lose traction and the ESC system
becomes active. The ESC Activation/Malfunction Indicator
Light also flashes when TCS is active. If the ESC
Activation/Malfunction Indicator Light begins to flash
during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions.
The ESC OFF Indicator Light indicates that the
Electronic Stability Control (ESC) is in a reduced
mode.
NOTE:
The ESC Activation/Malfunction Indicator Light and the
ESC OFF Indicator Light come on momentarily each
time the ignition is placed in the ON/RUN mode.
 Each time the ignition is placed in the ON/RUN mode,
the ESC system will be on even if it was turned off previ -
ously.
 The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
Hill Start Assist (HSA)
HSA is designed to mitigate roll back from a complete stop
while on an incline. If the driver releases the brake while
stopped on an incline, HSA will continue to hold the brake
pressure for a short period. If the driver does not apply the
throttle before this time expires, the system will release
brake pressure and the vehicle will roll down the hill as
normal. The following conditions must be met in order for HSA to
activate:

The feature must be enabled.
 The vehicle must be stopped.
 The parking brake must be off.
 The driver door must be closed.
 The vehicle must be on a sufficient grade.
 The gear selection must match vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE gear).
 HSA will work in REVERSE gear and all forward gears.
The system will not activate if the transmission is in
PARK or NEUTRAL.
Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
If disabling HSA using Uconnect Settings
Úpage 191.
Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.
WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur, such
as on minor hills or with a loaded vehicle, or while
pulling a trailer. HSA is not a substitute for active driving
involvement. It is always the driver’s responsibility to be
attentive to distance to other vehicles, people, and
objects, and most importantly brake operation to
ensure safe operation of the vehicle under all road
conditions. Your complete attention is always required
while driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a collision
or serious personal injury.
WARNING!
If you use a trailer brake controller with your trailer,
the trailer brakes may be activated and deactivated
with the brake switch. If so, there may not be enough
brake pressure to hold both the vehicle and the
trailer on a hill when the brake pedal is released. In
order to avoid rolling down an incline while resuming
acceleration, manually activate the trailer brake or
apply more vehicle brake pressure prior to releasing
the brake pedal.
 HSA is not a parking brake. Always apply the parking
brake fully when exiting your vehicle. Also, be certain
to place the transmission in PARK.
 Failure to follow these warnings can result in a colli -
sion or serious personal injury.

TIRE PRESSURE MONITORING SYSTEM
(TPMS)
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
pressure 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 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 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. The tire pressure will also increase as the
vehicle is driven — this is normal and there should be no
adjustment for this increased pressure.
See
Úpage 370 on how to properly inflate the vehicle’s
tires. 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
Úpage 402.
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, 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 original equip -
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equip -
ment 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 func -
tion checked.
 After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois -
ture and dirt from entering the valve stem, which
could damage the TPMS sensor.

278SAFETY
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, unless your vehicle
is equipped with a Tire Fill Alert (TFA) system.
 Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla -
tion 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 underinflation has not reached the level
to trigger illumination of the TPMS Warning Light.
 Seasonal temperature changes will affect tire pres -
sure, and the TPMS will monitor the actual tire pres -
sure in the tire.

Tire Pressure Monitoring System 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 System sensors
 Various Tire Pressure Monitoring System messages,
which display in the instrument cluster
 Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring System Low
Pressure Warnings
The 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 automatically update, the
graphic display in the instrument cluster will return to its
original color, and the Tire Pressure Monitoring 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
recommended cold placard pressure in order to turn the
Tire Pressure 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.
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 driving
next to facilities emitting the same radio frequencies
as the Tire Pressure Monitoring System 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 TPMS sensors
A system fault may occur due to an incorrect TPMS sensor
location condition. When a system fault occurs due to an
incorrect TPMS 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 TPMS 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
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 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.
You may choose to disable or enable the Tire Fill Alert
feature through use of the Uconnect 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).
6

23_DT_OM_EN_USC_t.book Page 279

280SAFETY
The system will be activated when a positive increase in
tire pressure is detected by the TPMS while inflating the
tire. The ignition must be in the RUN mode, with the
transmission in PARK.
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.
If the hazard lamps do not come on while inflating the tire,
the TPMS sensor may be out of range preventing the TPMS
sensor signal from being received. In this case, the vehicle
may need to be moved either forward or backward slightly
to exit the null spot.
Operation:
The horn will sound once to let the user know when to
stop filling the tire, when it reaches recommended
pressure.
 The horn will sound three times if the tire is overfilled
and will continue to sound every five seconds if the
user continues to inflate the tire.
 The horn will sound once again when enough air is let
out to reach proper inflation level.
 The horn will also sound three times if the tire is then
underinflated and will continue to sound every five
seconds if the user continues to deflate the tire.
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
warns the driver of a low tire pressure event based on the
driver’s 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 driver’s
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 can
support up to 12 trailer tires per configured trailer on up to
four configurable trailers
Úpage 191.

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.
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 selecting
trailer. Select the desired trailer profile to pair to, open the
“Tire Pressure” menu, and hit “Setup All Tires”
Úpage 191.
NOTE:The vehicle may not be driven until the pairing process is
complete.

SAFETY281

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 three 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 indi -
cating 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 System 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.
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 its 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 TTPMS
instrument cluster graphic when a trailer number is
selected that has not had trailer tire pressure sensors
paired. To correct this condition, see
Úpage 191.
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
TTPMS 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 TTPMS module.
To correct this condition, the correct trailer number must
be selected in the radio
