Tire Pressure Monitor Warning Display
As soon as a wheel sensor senses a significant loss of air pressure in one or more tires, the sensor(s) sends signals (values) to the tire pressure monitoring antenna which then transfers the values to the tire pressure control module. The control module transfers the values to the driver information system in the instrument cluster which displays a flat tire symbol and text message which reads "CHECK TIRE PRESSURE". After a few seconds, the message is replaced by the regular display (press CHECK button to show message again).
The low pressure warning light in the instrument cluster illuminates when:
- Tire pressure is 7 psi (48 kPa) lower than it should be.
- One or more wheels are installed without a tire pressure sensor.
- Winter tires are installed.
- Incorrect pressure sensors are installed.
When a tire pressure monitoring system malfunction occurs, it will be indicated when the ignition is turned ON and the yellow malfunction lamp in the instrument cluster will flash for one minute and then stay ON, and a yellow TPMS is shown in the display (on newer models, more explicit messages may be displayed).
