Check the tire pressure periodically (at least
monthly) using an accurate tire gauge. See
Inflating Your Tires in this chapter.
Understanding Your Tire Pressure
Monitoring System
The tire pressure monitoring system
measures pressure in your four road tires
and sends the tire pressure readings to your
vehicle. 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.
When Your Temporary Spare Tire is
Installed
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.
To restore the full function of the tire
pressure monitoring system, have the
damaged road wheel and tire assembly
repaired and remounted on your vehicle.
When You Believe Your System is Not
Operating Properly
The main function of the tire pressure
monitoring system is to warn you when your
tires need air. It can also warn you in the
event the system is no longer capable of
functioning as intended. See the following
chart for information concerning your tire
pressure monitoring system:
