120 SAFETY
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 sensors.
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster.
Tire Pressure Monitoring Light.
Tire Pressure Monitoring Low Pressure Warn-
ings
The “Tire Pressure Monitoring 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 instrument
cluster will display a "Tire Low" message for a
minimum of five seconds and a graphic showing
the pressure values of each tire with the low tire
pressure values in a different color.
Tire Pressure Monitoring Low Pressure Warning
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 “Tire
Pressure Monitoring 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 Tire Pressure Moni-
toring 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 “Tire
Pressure Monitoring 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 key is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the “Tire
Pressure Monitoring 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
