Tire Pressure Monitor System — If Equipped
The Tire Pressure Monitor (TPM) system uses wireless
technology to monitor tire pressure levels. Sensors,
mounted to each wheel as part of the valve stem transmit
tire pressure readings to a receiver located in the over-
head console.
The tire pressure is shown in the Electronic Vehicle
Information Center (EVIC) display. The TPM system
remains active even if it is not displayed in the EVIC.
CAUTION!
The TPM system is designed to monitor your tire
pressure and will not function as a tire pressure
gauge while adjusting the pressure in your tires.
There will be a delay between the instant you adjust
the air pressure in a tire and when the system
updates the display.
NOTE: The TPM system can inform you about a low or
high tire pressure condition, but it does not replace
normal tire maintenance.
The TPM system is not intended to provide you with
notification of rapid pressure loss.
