SAFETY 311
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 its original color, and the
Tire Pressure Monitoring System Warning 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 Monitoring System Warning Light off.
Service TPMS Warning
If a system fault is detected, the TPMS 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 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 TPMS 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:

Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies
as the TPMS 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 TPMS sensors.
A system fault may occur due to an incorrect TPMS sensor
location condition. When a system fault occurs due to an
incorrect TPMS sensor location, the TPMS 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 “Tire Pressure
Temporarily Unavailable” message in place of the tire
pressure display screen. If the ignition switch is cycled,
this sequence will repeat, providing the system fault still
exists. If the system fault no longer exists, the TPMS
Warning Light will no longer flash and the tire pressure
display screen will be displayed showing the tire pressure
values in the correct locations.
Vehicles With Non-Matching Full Size Spare Or Compact
Spare

The non-matching full size spare or compact spare tire
does not have a TPMS sensor. Therefore, the TPMS will
not monitor the pressure in the non-matching full size
spare or compact spare tire.
 If you install the non-matching full size spare or
compact spare tire in place of a road tire that has a
pressure below the low-pressure warning limit, upon
the next ignition switch cycle, the TPMS Warning Light
and a “LOW TIRE” message will remain on and a chime
will sound. In addition, the graphic in the instrument
cluster will still display a pressure value in a different
color and an “Inflate to XX” message.
