Tire Pressure Monitoring Low Pressure
Warnings
The “Tire Pressure Monitoring Telltale
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 graphic
showing the pressure values of each tire with
the low tire pressure values in a different color.
An "Inflate to XX" message will also be
displayed.
Example: Low Tire Pressure Display
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 vehicle’s
recommended cold placard pressure inflation
value as shown in the "Inflate to XX" message.
Once the system receives the updated tire
pressures, the system will automatically
update, the graphic display in the instrument
cluster will return to it’s original color, and the
“Tire Pressure Monitoring Telltale Light” will
turn 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.
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 Moni

Service TPMS Warning
If a system fault is detected, the “Tire Pressure
Monitoring Telltale 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 switch is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the “Tire
Pressure Monitoring Telltale 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:
Signal interference due to electronic devices
or driving next to facilities emitting the same
radio frequencies as the TPM sensors.
Installing aftermarket window tinting that
contains materials that may block radio wave
signals.
Accumulation of snow or ice around the
wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPM
sensors.
A system fault may occur due to an incorrect
TPM sensor location condition. When a system
fault occurs due to an incorrect TPM sensor
location, the “Tire Pressure Monitoring Telltale
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
