Tire Pressure Monitoring System Warning Light
TIRE PRESSURE MONITORING SYSTEM LOW
PRESSURE WARNINGS
The TPMS Warning Light will illuminate in the
instrument cluster and a chime will sound
when tire pre ssur e is low in one o r more of
the four active road tires. In addition, t he
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 occu r, you should stop as soon as possible
and inflate the ti re s with low pressure (those i n 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 soli d. The system fault will also sound a
chime. In addi tio n, the instrument cluster will di splay a
"SERVICE TIRE PRESSURE SYSTEM" message for a mini-
mum of five seconds and then display dashes (--) in
place of the pressure value to indicate which sensor is
not being received.
If the igniti on is cycled, this sequence will repeat, pro-
viding 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” mes-
sage 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 chai ns on the vehicle
•
Using wheels/tires not equipped with TPMS sensors
Vehicles With A Full-Size Matching Spare
1. If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, it has a Tire Pres-
sure Monitoring System sensor, and can be moni-
tored 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 igni-
tion 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 di splay will still show the low tire pres-
sure 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.
TPMS DEACTIVATION — IF EQUIPPED
The TPMS can be deactivated if replacing all four wheel
and tire as semblie s (road tires) with wheel and tire
assemblies that d o not have TPMS sensors, such as
when installing winter wheel and ti re assemblies on
your vehicle.
To deactivate the TPMS, first replace all four wheel and
tire assemblies (road tires) with t ir es not equipped with
Tire Pressure Monitoring System sensors. Then, drive
the vehicle for 20 minutes above 15 mph (24 km/h).
The TPMS will chime, the TPMS Warning Light will flash
on and off for 75 seconds and then remain on. The
instrument cluster will display the “SERVICE TIRE PRES-
SURE SYSTEM” message and then display dashes (--) in
place of the pressure values.
