TPMS RAM CHASSIS CAB 2022 User Guide

274SAFETY
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.
If the hazard lamps do not come on while inflating
the tire, the TPMS sensor may be in a null spot
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.
When Tire Fill Alert mode is entered, the tire
pressure display screen will be displayed in the
instrument cluster.
Operation:
The horn will chirp once to let the user know
when to stop filling the tire, when it reaches
recommended pressure.
The horn will chirp three times if the tire is over -
filled and will continue to chirp every five
seconds if the user continues to inflate the tire.
The horn will chirp once again when enough air
is let out to reach proper inflation level.
The horn will also chirp three times if the tire is
then underinflated and will continue to chirp
every five seconds if the user continues to
deflate the tire.
SELECTABLE TIRE FILL ALERT (STFA) —
IF EQUIPPED
The Selectable Tire Fill Alert (STFA) system is an
optional feature that is included as part of the
normal Tire Fill Alert system. The system is
designed to allow the customer to select a
pressure to inflate or deflate the vehicle's front and
rear axle tires to and to provide feedback to the
customer while inflating or deflating the vehicle's
tires.
In the Selectable Tire Fill Alert application, which is
located in the apps menu of the Uconnect system,
the customer will be able to select a pressure
setting for both the front and rear axle tire
pressures by scrolling through a pressure range
from XX to 15 psi in 1 psi increments for each axle
setting. XX = the vehicle’s cold placard pressure
values for the front and rear axles as shown on the
vehicle placard pressure label.
NOTE:The Tire Fill Alert feature disables every time the
ignition is placed in the OFF position. The feature
must be re-enabled through the radio each time
the ignition is placed back in the ON/RUN position
Ú page 191.
The customer may also store the pressure values
chosen for each axle in the radio as a preset
pressure. The customer will be allowed to store up
to two sets of preset values in the radio for the
front and rear axle pressure values. Once the customer selects the tire pressures for
the front and rear axles that they want to inflate or
deflate to, they can begin inflating or deflating one
tire at a time.
NOTE:The STFA system will only support inflating or
deflating one tire at a time.
The customer may choose to disable or enable the
STFA feature through use of the TFA settings in the
radio. If STFA appears grayed out it must be turned
on prior to selecting.
In order to use STFA, the Tire Fill Alert feature must
be enabled through the radio Ú
page 191.
The system will be activated when the TPMS
receiver module detects a change in tire pressure.
The ignition must be in the RUN mode, with the
transmission in PARK (P).
The hazard lamps will come on to confirm the
vehicle is in Tire Fill Alert mode.
If the hazard lamps do not come on while inflating
or deflating the tire, the TPMS sensor may be in a
null spot 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.
When Tire Fill Alert mode is entered, the tire
pressure display screen will be displayed in the
instrument cluster.

SAFETY275
Operation:
The horn will chirp once when the selected pres -
sure is reached to let the user know when to
stop inflating or deflating the tire.
The horn will chirp three times if the tire is over -
inflated or over deflated and will continue to
chirp every five seconds if the user continues to
inflate or deflate the tire.
The horn will chirp once again when enough air
is added or removed to reach proper selected
pressure level.
Tire Pressure Information System (TPIS)
3500/4500/5500 Series Trucks
Your vehicle may be equipped with a Tire Pressure
Information System (TPIS).
The Tire Pressure Information System (TPIS) uses
wireless technology with wheel rim mounted
electronic sensors to transmit 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 TPIS consists of the following components:
Receiver module
Four TPMS sensors (Single Rear Wheel (SRW)
applications)
Six TPMS sensors (Dual Rear Wheel (DRW)
applications)
Pressure display in the instrument cluster
The TPIS will display all four (Single Rear Wheel
(SRW) applications) or six (Dual Rear Wheel (DRW)
applications) tire pressure values in the instrument
cluster display.
If a system fault is detected, 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 "SERVICE TPM
SYSTEM" message will no longer be displayed, 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 TPMS 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.
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.

SERVICING AND MAINTENANCE385
condition, please replace the TPMS sensor as it is
not designed to be reused when driven under Run
Flat mode 14 psi (96 kPa) condition.
NOTE:TPMS Sensor must be replaced after driving the
vehicle on a flat tire condition.
It is not recommended driving a vehicle loaded at
full capacity or to tow a trailer while a tire is in the
Run Flat mode.
See the Tire Pressure Monitoring System section
for more information.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions,
do not spin your vehicle's wheels above 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping.
Tread Wear Indicators
Tread wear indicators are in the original equipment
tires to help you in determining when your tires
should be replaced.

Tire Tread

These indicators are molded into the bottom of the
tread grooves. They will appear as bands when the
tread depth becomes a 1/16 of an inch (1.6 mm).
When the tread is worn to the tread wear
indicators, the tire should be replaced.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
Driving style.
Tire pressure - Improper cold tire inflation pres -
sures can cause uneven wear patterns to
develop across the tire tread. These abnormal
wear patterns will reduce tread life, resulting in
the need for earlier tire replacement.
Distance driven.
Performance tires, tires with a speed rating of V
or higher, and Summer tires typically have a
reduced tread life. Rotation of these tires per
the vehicle scheduled maintenance is highly
recommended.
NOTE:Wheel valve stem must be replaced as well when
installing new tires due to wear and tear in existing
tires.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause tire damage or failure. A tire could
explode and injure someone. Do not spin your
vehicle's wheels faster than 30 mph (48 km/h)
for more than 30 seconds continuously when
you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.
1 — Worn Tire
2 — New TireWARNING!
Tires and the spare tire should be replaced after
six years, regardless of the remaining tread.
Failure to follow this warning can result in
sudden tire failure. You could lose control and
have a collision resulting in serious injury or
death.
