SAFETY 165
Example: Tire Pressure Monitoring Display
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 sensors
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster
Tire Pressure Monitoring System Warning
Light
Tire Pressure Monitoring Low Pressure
Warnings
The “Tire Pressure Monitoring
Warning Light” will illuminate in the
instrument cluster when tire pressure
is low in one or more of the four active
road tires. In addition, the instrument cluster
will display a graphic showing the pressure
values of each tire with the low tire pressure
values in a different color. An "Inflate to XX"
message will also be displayed.
Example: Low Tire Pressure Display
Should this occur, you should stop as soon as
possible and inflate the tires with a low pressure
condition (those in a different color in the
instrument cluster 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 return to its original color, and the
“Tire Pressure Monitoring Telltale 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 Tire Pressure Moni-
toring Warning Light off.
Service TPMS Warning
If a system fault is detected, the “Tire Pressure
Monitoring 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 a
minimum of five seconds and then display
