Understanding the Tire Pressure
Monitoring System
The system measures the pressure in the
four road tires and sends the tire pressure
readings to your vehicle. The low tire
pressure warning lamp will illuminate if
any of the tire pressures are significantly
low. If the warning lamp is on you must
inflate one or more of the tires to the
correct pressure.
When the Spare Tire is Installed
If a road wheel and tire needs to be
replaced with the spare wheel, the system
will continue to identify a defect. You must
reset the system to make sure the sensor
in the spare wheel works correctly.
For additional information, see

Pressure Monitoring System Reset
Procedure
in this section.
When You Believe the System is Not
Operating Correctly
The main function of the system is to warn
you when the tire pressures are low. It can
also warn you in the event the system is
no longer capable of operating correctly.
