Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System Warning
Light will illuminate in the instrument cluster
and a chime will sound when tire pressure is
low in one or more of the four active road tires.
In addition, the instrument cluster will display a "Tire Low"
message, an "Inflate to XX" message, and a graphic
showing the pressure values of each tire with the low tire
pressure values highlighted or in a different color.
Tire Pressure Monitoring System Low Pressure Warning
Should this occur, you should stop as soon as possible and
inflate the tires with low pressure (those highlighted or in a
different color in the instrument cluster display graphic) to
the vehicle's recommended cold placard pressure value, as
shown in the "Inflate to XX" message. Once the system
receives the updated tire pressures, the system will
automatically update, the pressure values in the graphic
display in the instrument cluster will stop being highlighted
or return to their original color, and the Tire Pressure
Monitoring System Warning Light will turn off.
NOTE:
When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring System Warning Light off.
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.
Service TPMS Warning
When a system fault is detected, the Tire Pressure
Monitoring System Warning Light will flash on and off for
75 seconds and then remain on solid. The system fault will
also sound a chime. 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 to indicate which sensor is not being
received.
If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the Tire Pressure Monitoring System
Warning Light will no longer flash, and the "SERVICE TPM
SYSTEM" message will no longer display, and a pressure
value will display in place of the dashes. A system fault can
occur due to any of the following:
 Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors
 Installing some form of aftermarket window tinting that
affects radio wave signals
 Lots of snow or ice around the wheels or wheel hous-
ings
 Using tire chains on the vehicle
 Using wheels/tires not equipped with TPMS sensors
Vehicles With Compact Spare Or Non-Matching Full Size
Spare
1. The compact spare tire or non-matching full size
does not have a Tire Pressure Monitoring System
sensor. Therefore, the TPMS will not monitor the
pressure in the compact or non-matching full size
spare tire.
2. If you install the compact or non-matching full size
spare tire in place of a road tire that has a pressure
below the low-pressure warning limit, upon the next
ignition key cycle, the Tire Pressure Monitoring
System Warning Light will remain on and a chime will
sound. In addition, the graphic in the instrument
cluster will still display a different color or highlighted
pressure value and the "Inflate to XX" message.
3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the Tire Pressure Monitoring
System 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 five seconds and then display
dashes (--) in place of the pressure value.
4. For each subsequent ignition key cycle, a chime will
sound, the Tire Pressure Monitoring System 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 five
seconds and then display dashes (--) in place of the
pressure value.
