2023 RAM PROMASTER warning

SAFETY165
Turning FCW On Or Off
The FCW button is located in the Uconnect display
in the control settings Ú page 134.
To turn the FCW system on, press the forward
collision button once.
To turn the FCW system off, press the forward
collision button once.
NOTE:
Changing the FCW status to “Off” deactivates
the system, so no warning or active braking will
be available in case of a possible collision.
Changing the FCW status 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, but maintains the
audible and visual warnings.
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 kept in memory from
one ignition position to the next. If the system is
turned off, it will maintain its status in the next
key cycle.
FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking status are
programmable through the Uconnect system
Úpage 134.
Far
When the sensitivity of FCW is set to the
“Far” setting and the system status is
“Only Warning”, 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.
NOTE:The “Far” setting may result in a greater number of
FCW possible collision warnings experienced.
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 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
“Only Warning”, 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.
NOTE:The “Near” setting may result in a lesser number of
FCW possible collision warnings experienced.
FCW Limited Warning

If the instrument cluster displays “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.

If the front camera is blocked due to external
environmental conditions (i.e. heavy rain, snow,
fog), the system will be deactivated and a warning
message will display in the instrument cluster.6

23_VF_OM_EN_USC_t.book Page 165

166SAFETY
Service FCW Warning
If the system turns off, and the instrument cluster
displays: “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.
The “FCW Temporarily Unavailable” message can
sometimes be displayed while driving in highly
reflective areas (i.e. tunnels with reflective tiles, or
ice and snow). The system will recover after the
vehicle has left these areas. Under rare conditions,
when the camera is not tracking any vehicles or
objects in its path, this warning may temporarily
occur. If weather conditions are not a factor, the
driver should examine the fascia/bumper where
the camera is located. It may require cleaning or
removal of an obstruction from the fascia/bumper
cover.
The FCW Warning Light will appear on the
instrument cluster to indicate the front camera
is obstructed by sun or other visibility reducing
weather.
NOTE:
If the “FCW Temporarily Unavailable” message
occurs frequently (e.g. more than once on every
trip) without any snow, rain, mud, or other
obstruction, have the camera realigned at an
authorized dealer.
Installing a snow plow or front-end protector is
not recommended. Doing so may block the
camera and inhibit FCW operation.
Use only a soft cloth for cleaning. Do not use
solvents or abrasive pastes.
Precautions While Driving With FCW
In certain driving conditions, such as:
Driving in the vicinity of a curve
Small vehicles and/or not aligned to the lane
Lane changing of other vehicles
Passing of vehicles in an oncoming intersection
The intervention of the system could be
unexpected or delayed. The driver must therefore
always pay particular attention, while maintaining
control of the vehicle to drive in complete safety. Driving In The Vicinity Of A Curve
Entering or exiting a large curve, the system could
detect the presence of a vehicle that is in front of
the vehicle, but that does not preside in the same
lane. In cases such as this, the system might
respond.

Driving In The Vicinity Of A Curve

23_VF_OM_EN_USC_t.book Page 166

SAFETY167
Small Vehicles And/Or Not Aligned To The Lane
The system is not able to detect the presence of
vehicles that are in front of the vehicle but placed
outside the field of action of the camera and could
therefore not react in the presence of small
vehicles such as bicycles or motorcycles.

Small Vehicles And/Or Not Aligned To The Lane

Lane Changing Of Other Vehicles
Vehicles that suddenly change lanes, while staying
in the traffic lane of their vehicle and inside the
field of action of the camera, may cause the
intervention of the system.
Lane Changing Of Other Vehicles

Passing Of Vehicles In An Oncoming Intersection
The system could temporarily react to a vehicle
that crossed the range of the camera in an
oncoming intersection.

Passing Of Vehicles In An Oncoming Intersection

Pedestrian Emergency Braking (PEB) —
If Equipped
PEB is a subsystem of the Forward Collision
Warning (FCW) system which provides the driver
with audible warnings and visual warnings, in the
instrument cluster display. It may apply limited
automatic braking when it detects a potential
frontal collision with a pedestrian/cyclist.

PEB Message

If a PEB event begins at a speed below 39 mph
(62 km/h), the system may provide maximum braking
to mitigate the potential collision with a pedestrian/
cyclist. 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/
cyclist in front of you is no longer probable, the warning
message will be deactivated.

6

23_VF_OM_EN_USC_t.book Page 167

168SAFETY
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/cyclist.
PEB is turned on and off using the FCW button in
the Uconnect display in the control settings.
Ú page 134.
TIRE PRESSURE MONITORING
S
YSTEM (TPMS)
The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold placard pressure. 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 249 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.
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 tire pressure warning (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.

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.

23_VF_OM_EN_USC_t.book Page 168

SAFETY169
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.
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.
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 Ú page 280.
Base System
This is the TPMS Warning Light located in
the instrument cluster.
The 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 regularly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module
Four Tire Pressure Monitoring System sensors
Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System Warning Light
will illuminate in the instrument cluster, an audible
chime will be activated, and the “Check tire
pressure” message will display when one or more
of the four active road tire pressures are low.
Should this occur, you should stop as soon as
possible, check the inflation pressure of each
tire on your vehicle, and inflate each tire to the
vehicle’s recommended cold placard pressure
value. The system will automatically update and
the Tire Pressure Monitoring System Warning Light
will extinguish once the updated tire pressures
have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
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.

Check TPMS Warnings
The Tire Pressure Monitoring System Warning Light
will flash on and off for 75 seconds and remain on
solid when a system fault is detected, an audible
chime will be activated and the “Tire Pressure
Monitoring Unavailable” message will display.
If the ignition key is cycled, this sequence will
repeat providing the system fault still exists.
The TPMS Warning Light will turn off when the
fault condition no longer exists. A system fault can
occur with any of the following scenarios:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors
Installing some form of aftermarket window
tinting that affects radio wave signals
Snow or ice around the wheels or wheel
housings
Using tire chains on the vehicle
Using wheels/tires not equipped with TPMS
sensors
NOTE:Your vehicle is equipped with a regular size spare
wheel.

1. The spare tire does not have a TPMS sensor.
Therefore, the TPMS will not monitor the
pressure in the spare tire.
2. If a spare tire not equipped with the Tire
Pressure Monitoring System sensor is used,
the TPMS Warning Light will turn on, flashing
for 75 seconds and then remaining solid for
each subsequent ignition key cycle.
3. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the
spare tire, the TPMS will update automatically
and the Tire Pressure Monitoring System
Warning Light will extinguish once the updated
tire pressures have been received. The vehicle
may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this
information.
NOTE:For correct Tire Pressure Monitoring System
behavior, please wait for about 20 minutes in
key-off during each tire substitution.
OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your
vehicle are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air Bags
Child Restraints Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others.
If you are not sure, ask an authorized dealer.
IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your passengers
as safe as possible.
Here are some simple steps you can take to
minimize the risk of harm from a deploying air bag:

1. Children 12 years old and under should
always ride buckled up in the rear seat of a
vehicle with a rear seat.

2. A child who is not big enough to wear the vehicle seat belt properly must be secured in the
appropriate child restraint or belt-positioning
booster seat in a rear seating position

Ú
page 185.

3. If a child from 2 to 12 years old (not in a rear-facing child restraint) must ride in the
front passenger seat, move the seat as far
back as possible and use the proper child
restraint Ú page 185.
4. Never allow children to slide the shoulder belt behind them or under their arm.

23_VF_OM_EN_USC_t.book Page 170

SAFETY171
(Continued)
5. You should read the instructions provided with
your child restraint to make sure that you are
using it properly.
6. All occupants should always wear their lap and shoulder belts properly.
7. The driver and front passenger seats should be moved back as far as practical to allow the
front air bags room to inflate.
8. Do not lean against the door or window. If your vehicle has side air bags, and deployment
occurs, the side air bags will inflate forcefully
into the space between occupants and the
door and occupants could be injured.
9. If the air bag system in this vehicle needs to be modified to accommodate a disabled person,
see Úpage 275 for customer service contact
information.
SEAT BELT SYSTEMS
Buckle up even though you are an excellent driver,
even on short trips. Someone on the road may be
a poor driver and could cause a collision that
includes you. This can happen far away from home
or on your own street.
Research has shown that seat belts save lives, and
they can reduce the seriousness of injuries in a
collision. Some of the worst injuries happen when
people are thrown from the vehicle. Seat belts
reduce the possibility of ejection and the risk of
injury caused by striking the inside of the vehicle.
Everyone in a motor vehicle should be belted at
all times.
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 BeltAlert feature is active
whenever the ignition switch is in the AVV (START)
or MAR (ACC/ON/RUN) position.
Initial Indication
If the driver is unbuckled when the ignition switch
is first in the AVV (START) or MAR (ACC/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 AVV (START) or MAR (ACC/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.
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious injury
to a child 12 years or younger, including a
child in a rear-facing child restraint.
Never install a rear-facing child restraint in the
front seat of a vehicle. Only use a rear-facing
child restraint in the rear seat. If the vehicle
does not have a rear seat, do not transport a
rear-facing child restraint in that vehicle.
WARNING!

(Continued)
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.

Change Of Status
If the driver or outboard front seat passenger
(if equipped with outboard front passenger seat
BeltAlert) unbuckles their seat belt while the
vehicle is traveling, the BeltAlert warning sequence
will begin until the seat belts are buckled again.
The outboard front passenger seat BeltAlert is not
active when the outboard front passenger seat is
unoccupied. BeltAlert may be triggered when an
animal or other items are placed on the outboard
front passenger seat or when the seat is folded flat
(if equipped). It is recommended that pets be
restrained in the rear seat (if equipped) in pet
harnesses or pet carriers that are secured by seat
belts, and cargo is properly stowed.
BeltAlert can be activated or deactivated by
an authorized dealer. FCA US LLC does not
recommend deactivating BeltAlert.
NOTE:If BeltAlert has been deactivated and the driver
or outboard front seat passenger (if equipped
with outboard front passenger seat BeltAlert) is
unbuckled the Seat Belt Reminder Light will turn
on and remain on until the driver and outboard
front seat passenger seat belts are buckled.
Lap/Shoulder Belts
All seating positions in your vehicle are equipped
with lap/shoulder belts.
The seat belt webbing retractor will lock only during
very sudden stops or collisions. This feature allows
the shoulder part of the seat belt to move freely
with you under normal conditions. However, in a
collision the seat belt will lock and reduce your risk
of striking the inside of the vehicle or being thrown
out of the vehicle.
WARNING!
Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain you
properly. In some collisions, the air bags won’t
deploy at all. Always wear your seat belt even
though you have air bags.
In a collision, you and your passengers can
suffer much greater injuries if you are not
properly buckled up. You can strike the inte
-
rior of your vehicle or other passengers, or you
can be thrown out of the vehicle. Always be
sure you and others in your vehicle are
buckled up properly.
It is dangerous to ride in a cargo area, inside
or outside of a vehicle. In a collision, people
riding in these areas are more likely to be
seriously injured or killed.
Do not allow people to ride in any area of your
vehicle that is not equipped with seats and
seat belts.

Be sure everyone in your vehicle is in a seat and
using a seat belt properly. Occupants, including
the driver, should always wear their seat belts
whether or not an air bag is also provided at their
seating position to minimize the risk of severe
injury or death in the event of a crash.
