SAFETY 131
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. Underinfla-
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate 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 pres-
sure, and the TPMS will monitor the actual tire pres-
sure in the tire.
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
Ú page 233.
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.
Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System (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 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 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 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 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.
