Understanding the Tire Pressure
Monitoring System
The system measures the pressure in the
four road tires and displays the readings in
the instrument cluster.
The system detects this lower pressure as
being significantly below the correct
inflation pressure and the warning lamp
illuminates. You must inflate the tires to
the correct pressure.
When the Temporary Spare Tire is
Installed
If you need to replace a road wheel and
tire with the temporary spare wheel, the
system will continue to identify a defect.
This is to remind you to repair the damaged
road wheel and tire and refit the repaired
road wheel and tire assembly to your
vehicle. To restore the correct operation
of the system, you must have the repaired
road wheel and tire assembly refitted to
your vehicle.
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.
See the following chart for information
concerning the system:
