SAFETY285
Follow the on screen prompts to select the number
of axles (1-3), the number of trailer tires (2, 4, 6, 8,
or 12), and the set trailer tire pressure. The range
is selectable anywhere between 25-125 psi
(172-862 kPa).
Once psi (kPa) is programmed, the pairing screen
appears. Tire sensors must be paired in order
shown. Starting with Tire 1, deflate tire by 5 psi
(34 kPa) and wait for a horn chirp. It may take up
to three minutes for the chirp to occur, indicating
that the sensor has paired. Repeat process on
each tire, in order, until complete. Do not exit the
pairing screen until process is complete. If pairing
was unsuccessful, a double horn chirp will sound,
and a prompt on the touchscreen will allow you to
retry the procedure; “Retry” will only appear when
setup fails. Each tire must be successfully paired
during a single pairing process to receive the
success screen.
NOTE:If the pairing process times out after three minutes
of no communication with a sensor, a double horn
chirp will occur indicating the pairing has failed and
a message will display on the radio indicating the
process was unsuccessful. Under certain circum -
stances, the double horn chirp may continue to
happen every three minutes indicating the failed
pairing. If this happens, the horn chirping may be
canceled by cycling the ignition button OFF and
then back to ON/RUN position. Trailer Tire Pressure Monitoring System Low
Pressure Warnings
When a low tire pressure in one or more of the
active road tires is detected, the instrument cluster
will display a message stating “Trailer Tire
Pressure Low”. The instrument cluster will then
display the TTPMS graphic showing the pressure
values of each tire with the low tire pressure values
in a different color.

Should this occur, you should stop as soon as possible
and inflate the tires with a low pressure condition
(those in a different color in the instrument cluster
graphic) to the customer programmed target tire
pressure value as shown at the top of the TTPMS
instrument cluster graphic. Once the tire(s) are inflated,
the system will automatically update the graphic
display in the instrument cluster, returning to its
original color. The vehicle may need to be driven for up
to 10 minutes above 15 mph (24 km/h) in order for the
TTPMS to receive the updated information.

Service TTPMS Warning
If a system fault is detected, the instrument cluster
will display a “Trailer Tire Pressure System Service
Required” message for a minimum of five seconds.
Once the system fault is corrected the "Trailer Tire
Pressure System Service Required" message will
no longer be displayed. The vehicle may need to be
driven for up to 10 minutes above 15 mph
(24 km/h) in order for the TTPMS to receive the
trailer tire pressure information. Trailer Tire Pressure System Not Configured
A “Trailer Tire Pressure System Not Configured”
message will be displayed in the instrument
cluster on the TTPMS instrument cluster graphic
when a trailer number is selected that has not had
trailer tire pressure sensors paired Ú
page 199.
Trailer Sensors Detected Do Not Match Active
Trailer
The “Trailer Sensors Detected Do Not Match Active
Trailer” message will be displayed in the
instrument cluster when the trailer sensors being
received by the TTPMS module do not match the
trailer sensors paired to the current trailer number
selected. This message will be displayed when the
sensors being received completely match the
sensors paired to another trailer number
configured in the TTPMS module.
To correct this condition, the correct trailer number
must be selected in the radio Ú page 199.
System Limitations
The TTPMS may have difficulty transmitting
through steel-walled tires or on trailers longer than
30 ft. It is recommended to use standard tires and
trailers less than 30 ft long to avoid dropouts or
difficulty when pairing.
NOTE:The vehicle may not be driven until the pairing
process is complete.
