Occupant Restraint Systems; Occupant Restraint Systems Features - RAM 2500 2023 Owner's Manual

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 Warning Flashers will come on to confirm the
vehicle is in Tire Fill Alert mode.
If the Hazard Warning Flashers do not come on while
inflating or deflating the tire, the TPMS sensor may be in
an inoperative position, preventing the TPMS sensor
signal from being received. In this case, the vehicle may
need to be moved slightly forward or backward.
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 when the selected pressure 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 overinflated
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 Series Trucks
Your vehicle may be equipped with a TPIS.
The 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:
O R S
CCUPANT ESTRAINT YSTEMS
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.
