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.
●
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 Tire
Pressure Monitoring System (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.
Tire Fill Alert
This feature notifies the user when the placard tire
pressure is attained while inflating or deflating the tire.
You may choose to disable or enable the Tire Fill Alert
feature through use of the Uconnect Settings in the
radio.
NOTE:
●
Only one tire can be filled at a time when using the
Tire Fill Alert system.
●
The Tire Fill Alert feature cannot be entered if an
existing TPMS fault is set to “active” or if the system
is in deactivation mode (if equipped).
The system will be activated when a positive increase
in tire pressure is detected by the TPMS while inflating
the tire. The ignition must be in the RUN mode, with the
transmission in PARK.
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.
When Tire Fill Alert mode is entered, the tire pressure
display screen will be displayed in the instrument
cluster.
If the hazard lamps do not come on while inflating the
tire, the TPMS sensor may be out of range 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.
Operation:
●
The horn will sound once to let the user know when
to stop filling the tire, when it reaches recommended
pressure.
●
The horn will sound three times if the tire is overfilled
and will continue to sound every five seconds if the
user continues to inflate the tire.
●
The horn will sound once again when enough air is
let out to reach proper inflation level.
●
The horn will also sound three times if the tire is
then underinflated and will continue to sound every
five seconds if the user continues to deflate the tire.
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 driver’s set target tire pressure value, through
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 driver’s 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 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.
