312 SAFETY
After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the 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 TPMS Warning Light will flash on and off for
75 seconds and then remain on solid, and the instru-
ment 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 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.
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
drivers set target tire pressure value, through the 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 drivers
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

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”
Ú page 226.
NOTE:
The vehicle may not be driven until the pairing process is
complete.
