232 SAFETY
• Tire Pressure Monitoring Telltale Light
A tire pressure monitoring sensor is located in the spare
wheel, if the vehicle is equipped with a matching full-size
spare wheel and tire assembly. The matching full-size spare
tire can be used in place of any of the four road tires.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale 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 instru-
ment cluster will display a "LOW TIRE" message for a
minimum of five seconds. A graphic display of the pressure
value(s) with the low tire(s) highlighted or in a different
color will also be displayed. Refer to "Instrument Cluster
Display" in "Getting To Know Your Instrument Panel" for
further information.
NOTE: Your system can be set to display pressure units in
PSI, kPa, or BAR.
Tire Pressure Monitor 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 highlighted or shown in a different
color on the graphic display to the vehicle's recommended
cold tire pressure inflation value. The system will auto-
matically update, the graphic display of the pressure
value(s) will no longer be highlighted or shown in a
different color and the Tire Pressure Monitoring Telltale
Light will extinguish once the updated tire pressure(s)
have been received.
