SAFETY 227
NOTE:
The TPMS is not intended to replace normal tire
care and maintenance, or to provide warning of
a tire failure or condition.
The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi-
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu-
rate tire pressure gauge, even if underinflation
has not reached the level to trigger illumination
of the TPMS Warning Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
Premium System
The Tire Pressure Monitoring System (TPMS) uses
wireless technology with wheel rim mounted
electronic sensors to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the
receiver module.
NOTE:
It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module
Four Tire Pressure Monitoring System sensors
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster
Tire Pressure Monitoring System Warning Light
SERVICE TPMS WARNING
When a system fault is detected, the Tire Pressure
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 System 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 addition,
the graphic in the instrument cluster will still
display a different color pressure value.
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 TPM SYSTEM”
message for five seconds and then display
dashes
(- -)
in place of the pressure value.
