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 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 Inflating the Tires
