292 SAFETY
Tire Pressure Monitoring Low Pressure Warnings
When a tire pressure low in one or more of the
ac
tive 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
pos
sible 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
th
e TTPMS to receive the updated information.
Service TTPMS Warning
If a system fault is detected, the instrument cluster
wi
ll display a “Trailer Tire Pressure System Service
Required” message for a minimum of five seconds.
Once the system fault is corrected the "Trailer Tire
Pr
essure System Service Required" message will
no longer be displayed. The vehicle may need to be
driven for up to 10
minutes above 15 mph
(2
4 km/h) in order for the TTPMS to receive the
tr
ailer tire pressure information.
Trailer Tire Pressure System Not Configured
A “Trailer Tire Pressure System Not Configured”
m
e
ssage 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. To correct this
condition, see
Ú page 229.
Trailer Sensors Detected Do Not Match Active
T
r
ailer
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
mu
st be selected in the radio Ú page 229.
System Limitations
TTPMS may have difficulty transmitting through
s
t
eel-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 drop outs or difficulty
when pairing.
NOTE:
The vehicle may not be driven until the pairing
pr
ocess is complete.
Tire Fill Alert
This feature notifies the user when the placard tire
pressure is attained while inflating or deflating the
tire.
The customer may choose to disable or enable the
Ti
re Fill Alert feature through use of the customer
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 the system
de
tects an increase of tire pressure, while filling
the fire. The ignition must be in the RUN mode, with
the transmission in PARK (P).
NOTE:
It is not required to have the engine running to
en
ter Tire Fill Alert mode.
The hazard lamps will come on to confirm the
vehicle is in Tire Fill Alert mode.
If the hazard lamps do not come on while inflating
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.
