SAFETY 169
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
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.
Tire Pressure Monitoring System
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. 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 Tire Pres-
sure Monitoring System (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 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 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:
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 Compact Spare — If Equipped
1. The compact spare tire does not have a tire
pressure monitoring sensor. Therefore, the
TPMS will not monitor the pressure in the
compact spare tire.
2. If you install the compact spare tire 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 addi-
tion, the graphic in the instrument cluster
will still display a different color pressure
value.
