266 SAFETY
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.
Tire Pressure Monitoring System Display
NOTE:
It is particularly important for you to regularly check
the tire pressure in all of your tires and to maintain
the proper pressure.
The Tire Pressure Monitoring System (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, and a graphic displaying tire pressures
TPMS Warning Light
Tire Pressure Monitoring System Low
Pressure Warnings
The TPMS Warning Light will illuminate in
the instrument cluster, and an audible
chime will be activated, when one or
more of the four active road tire
pressures are low. In addition, the instrument
cluster will display an "Inflate to XX" message and
a graphic display of the pressure value(s) with the
low tire(s) in a different color Ú page 99.
NOTE:
Your system can be set to display pressure units in
PSI, BAR, or kPa.
Low Tire Pressure Monitoring System Display
Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as
possible, and inflate the low tire(s) that is in a
different color on the graphic display to the
vehicle’s recommended cold tire pressure
displayed in the “Inflate to XX” message.
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.
The system will automatically update, the graphic
display of the pressure value(s) will return to its
original color and the TPMS Warning Light will
extinguish once the updated tire pressure(s) have
been received. The system will automatically
update the graphic display of the pressure value(s)
and will return to its original color. The TPMS
Warning Light will extinguish once the updated tire
pressure(s) have been received in the case when
the ignition is ON. In the case when the ignition is
OFF, the ignition on the vehicle has to be turned ON
and may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this
information for the pressure value(s) to be
updated.
