Lincoln Aviator: Tire Pressure Monitoring System / Understanding Your Tire Pressure Monitoring System
The tire pressure monitoring system
measures pressure in your road tires and
sends the tire pressure readings to your
vehicle. You can view the tire pressure
readings through the information displa. The low
tire pressure warning light will turn on if the
tire pressure is significantly low. Once the light is illuminated, your tires
are
under-inflated and need to be inflated to the
manufacturer’s recommended tire pressure.
Even if the light turns on and a short time
later turns off, your tire pressure still needs
to be checked.
Note: Each road tire is equipped with a tire
pressure sensor located inside the wheel
and tire assembly cavity. The pressure
sensor is attached to the valve stem...
When one of your road tires needs to be
replaced with the temporary spare, the
system will continue to identify an issue to
remind you that the damaged road wheel
and tire assembly needs to be repaired and
put back on your vehicle...
