2022 RAM 1500 warning light

SAFETY321
The BSM system monitors the detection zone from
three different entry points (side, rear, front) while
driving to see if an alert is necessary. The BSM
system will issue an alert during these types of
zone entries.
Entering From The Side
Vehicles that move into your adjacent lanes from
either side of the vehicle.

Side Monitoring
Entering From The Rear
Vehicles that come up from behind your vehicle on
either side and enter the rear detection zone with
a relative speed of less than 30 mph (48 km/h).

Rear Monitoring

Overtaking Traffic
If you pass another vehicle slowly with a relative
speed less than 15 mph (24 km/h) and the vehicle
remains in the blind spot for approximately 1.5
seconds, the warning light will be illuminated. If the
difference in speed between the two vehicles is
greater than 15 mph (24 km/h), the warning light
will not illuminate.
Overtaking/Approaching
Overtaking/Passing

The BSM system is designed not to issue an alert
on stationary objects such as guardrails, posts,
walls, foliage, berms, snow banks, car washes, etc.
However, occasionally the system may alert on
such objects. This is normal operation and your
vehicle does not require service.

Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode, the BSM
system will provide a visual alert in the appropriate
side view mirror based on a detected object.
However, when the system is operating in Rear
Cross Path (RCP) mode, the system will respond
with both visual and audible alerts when a
detected object is present. Whenever an audible
alert is requested, the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/Chime
mode, the BSM system will provide a visual alert in
the appropriate side view mirror based on a
detected object. If the turn signal is then activated,
and it corresponds to an alert present on that side
of the vehicle, an audible chime will also be
sounded. Whenever a turn signal and detected
object are present on the same side at the same
time, both the visual and audible alerts will be
issued. In addition to the audible alert the radio (if
on) will also be muted.
NOTE:Whenever an audible alert is requested by the
BSM system, the radio is also muted. When the system is in RCP, the system shall
respond with both visual and audible alerts when a
detected object is present. Whenever an audible
alert is requested, the radio is also muted.
Turn/hazard signal status is ignored; the RCP state
always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off there will be no
visual or audible alerts from either the BSM, RCP,
or Trailer Merge Assist systems.
NOTE:The BSM system will store the current operating
mode when the vehicle is shut off. Each time the
vehicle is started the previously stored mode will
be recalled and used.
Trailer Merge Assist — If Equipped
Trailer Merge Assist is a function of the Blind Spot
Monitoring (BSM) system that extends the blind
spot zone to work while pulling a trailer.
NOTE:When Trailer Merge Assist is activated, Rear Cross
Path is disabled.
Trailer Merge Assist consists of three sub
functions:
Automatic Trailer Detection
Trailer Length Detection
Trailer Merge Warning

SAFETY325
Trailer length will be identified and placed into one
of the following categories:
Trailer length up to 10 ft (3 m) — Blind spot zone
will be adjusted to 10 ft (3 m) .
Trailer length between 10 ft to 20 ft (3 m to 6 m) — Blind spot zone will be adjusted to 20 ft
(6 m) .
Trailer length between 20 ft to 30 ft (6 m to 9 m) — Blind spot zone will be adjusted to 30 ft
(9 m) .
Trailer length between 30 ft and 39.5 ft (9 m to
12 m) — Blind spot zone will be adjusted to Max
distance .
NOTE:Trailer length is determined within +/- 3 ft (1 m) of
actual length. Trailers that are the same size as the
category limit, 10/20/30 ft (3/6/9 m), could be
subject to being placed in the category above or
below the correct one.
Trailer Merge Warning
Trailer Merge Warning is the extension of the blind
spot function to cover the length of the trailer, plus
a safety margin, to warn the driver when there is a
vehicle in the adjacent lane. The driver is alerted by
the illumination of the BSM warning light located in the outside mirror on the side the other vehicle is
detected on. In addition, an audible (chime) alert
will be heard and radio volume will be reduced
Ú
page 322.
NOTE:
The Trailer Merge Alert system DOES NOT alert
the driver about rapidly approaching vehicles
that are outside the detection zones.
The Blind Spot Monitoring (BSM) system may
experience drop outs (blinking on and off) of the
side mirror warning indicator lamps when a
motorcycle or any small object remains at the
side of the vehicle for extended periods of time
(more than a couple of seconds).
Crowded areas such as parking lots, neighbor -
hoods, etc. may lead to an increased amount of
false alerts. This is normal operation.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION — IF EQUIPPED
FCW with Mitigation 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 potential
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
progressive 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 warnings 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.
WARNING!
The Blind Spot Monitoring system is only an aid
to help detect objects in the blind spot zones.
The BSM system is not designed to detect
pedestrians, bicyclists, or animals. Even if your
vehicle is equipped with the BSM system, always
check your vehicle’s mirrors, glance over your
shoulder, and use your turn signal before
changing lanes. Failure to do so can result in
serious injury or death.

328SAFETY
If a PEB event begins at a speed below 37 mph
(60 km/h), the system may provide braking to
mitigate the potential collision with a pedestrian. If
the PEB event stops the vehicle completely, the
system will hold the vehicle at a standstill for two
seconds and then release the brakes. When the
system determines a collision with the pedestrian
in front of you is no longer probable, the warning
message will be deactivated.
The minimum speed for PEB activation is 3 mph
(5 km/h). Turning PEB On Or Off
NOTE:The default status of PEB is “On.” This allows the
system to warn you of a possible frontal collision
with the pedestrian.
The PEB button is located in the Uconnect display
in the controls settings Ú
page 234.
To turn the PEB system off, push the Pedestrian
Emergency Braking button once.
To turn the PEB system back on, push the
Pedestrian Emergency Braking button again.
Changing the PEB status to “Off” deactivates the
system, so no warning or active braking will be
available in case of a possible frontal collision with
the pedestrian.
NOTE:The PEB system will retain the last setting selected
by the driver after ignition shut down.
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 Ú page 444 on how to properly inflate the
vehicle’s tires.
WARNING!
Pedestrian Emergency Braking (PEB) is not
intended to avoid a collision on its own, nor can
PEB detect every type of potential collision with
a pedestrian. The driver has the responsibility to
avoid a collision by controlling the vehicle via
braking and steering. Failure to follow this
warning could lead to serious injury or death.

22_DT_OM_EN_USC_t.book Page 328

SAFETY329
(Continued)
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 Ú
page 480.
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.
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. Underinflation also reduces fuel effi
-
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
CAUTION!
The TPMS has been optimized for the original
equipment 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 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 pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the TPMS
sensor.
CAUTION!
6

22_DT_OM_EN_USC_t.book Page 329

330SAFETY
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu -
rate 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
pressure, and the TPMS will monitor the actual
tire pressure 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. There
-
fore, 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 pres -
sure 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).
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 over
-
filled 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.
