SAFETY 223
NOTE:
When filling warm tires, the tire pressure may need to be
incr
eased up to an additional 4 psi (28 kPa) above the recom-
mended cold placard pressure in order to turn the TPMS
W
arn
ing Light off.
The vehicle may need to be driven for up to 20 minutes
a
b
ov
e 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
emit
ting the same radio frequencies as the TPMS sensors.
• Installing some form of aftermarket window tinting that
aff
ects radio wave signals.
• Lots of snow or ice around the wheels or wheel housings.
• Usi
ng tire chains on the vehicle.
• Usi
ng wheels/tires not equipped with TPMS sensors.
Veh
icles With Compact Spare or Non-Matching Full Size
Spar
e
1. The compact spare tire or non-matching full size does not
hav
e a tire pressure monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the compact spare tire.
2. If you install the compact or non-matching full size spare
tir
e in place of a road tire that has a pressure below the
low-pressure warning limit, upon the next ignition cycle,
the TPMS Warning Light will remain on and a chime will
sound. In addition, the graphic in the instrument cluster
will still display a different color pressure value and an
"Inflate to XX" message.
