Various tire pressure monitoring system
messages, which display in the instrument
cluster
Tire pressure monitoring telltale light
Tire Pressure Monitoring Low Pressure
Warnings
The TPMS Warning Light will illumi-
nate 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 for a minimum
of five seconds, an "Inflate to XX" message
and a 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 low pres-
sure (those in a different color in the instru-
ment cluster graphic) to the vehicle’s recom-
mended cold placard pressure value as
shown in the "Inflate to XX" message. Once
the system receives the updated tire pres-
sures, the system will automatically update,
the pressure values in the graphic display in
the instrument cluster will return to their
original color, and the TPMS 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 plac-
ard pressure in order to turn the TPMS Warn-
ing 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 TPMS
Warning Light will flash on and off for 75 sec-
onds and then remain on solid. The system
fault will also sound a chime. In addition, the
instrument cluster will display a "SERVICE
TIRE PRESSURE 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.
