Tire Pressure Monitoring Low Pressure Warning
Should this occur, you should stop as soon as
possible and inflate the tires with low pressure
(those in a different color in the instrument
cluster 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 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 placard
pressure in order to turn the TPMS 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 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 "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.
If the ignition 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 TIRE PRESSURE 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 housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS
sensors.
Vehicles With a Full-Size Matching Spare
1. Your vehicle is equipped with a matching
full-size spare wheel and tire assembly, it
has a Tire Pressure Monitoring sensor, and
can be monitored by the Tire Pressure
Monitoring System (TPMS) when swapped
with a low pressure road tire.
2. In the event that the matching full-size spare
tire is swapped with a low pressure road tire,
the next ignition switch cycle will still show the
TPMS Warning Light to be on, a chime to
sound, an "Inflate to XX" message to appear
in the instrument cluster, and the graphic
display will still show the low tire pressure
value in a different color.
3. Driving the vehicle for up to 20 minutes
above 15 mph (24 km/h) will turn off the
TPMS Warning Light as long as none of road
tires are below the low pressure warning
threshold.
