Tire Pressure Monitoring System Low
Pressure Warnings
The TPMS Warning Light will illuminate 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 instru-
ment cluster will display an “Inflate to XX” message and a
graphic showing the pressure values of each tire with the
low tire pressure values shown in a different color.
Should this occur, you should stop as soon as possible
and inflate the tires with a low pressure condition
(those shown in a different color in the instrument clus-
ter 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 change
color back to the 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.
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.
Service Tire Pressure System Warning
If a system fault is detected, the Tire Pressure Monitor-
ing 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 instru-
ment cluster will display a "Service Tire Pressure Sys-
tem" 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 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:
•
Signal interference due to electronic devices or driv-
ing next to facilities emitting the same radio fre-
quencies as the TPMS sensors
•
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
Vehicles With Compact Spare
1. The compact spare tire or non-matching full size
does not have a Tire Pressure Monitoring System
sensor. Therefore, the TPMS will not monitor the
pressure in the compact or non-matching full size
spare tire.
2.
If you install the compact or non-matching full size
spare tire in place of a road tire that has a pressure
below the low-pressure warning limit, upon the next
ignition key 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.
3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), 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 Tire Pressure System” message for five
seconds and then display dashes (- -) in place of the
pressure value.
4. For each subsequent ignition key cycle, a chime will
sound, the TPMS Warning Light will flash on and off
for 75 seconds and then remain on solid, and the
instrument cluster will display a “Service Tire Pres-
sure System” message for five seconds and then
display dashes (- -) in place of the pressure value.
