TIRE” message will remain on and a chime
will sound. In addition, the graphic in the
instrument cluster will still display a pressure
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 TPMS Warning
Light will flash on and off for 75 seconds and
then remain on solid. In addition, 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.
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 instrument cluster
will display a "SERVICE TPM SYSTEM"
message for a minimum of five seconds and
then display dashes (- -) in place of the pres-
sure 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 Ú page 258.
Trailer Tire Pressure Monitoring System
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”

NOTE:
The vehicle may not be driven until the pairing
process is complete.
