Low Tire Inflation Monitor System 
(If Equipped)

The low tire inflation monitor system can alert you to a
large change in the pressure of one tire. The system
“learns” the pressure at each tire throughout the
operating speed range of your vehicle. The system
normally takes between 45 and 90 minutes of driving to
learn the tire pressures. This time may be longer
depending on your individual driving habits. Learning
need not be accumulated during a single trip. Once
learned, the system will remember the tire pressures
until the system is recalibrated.

After the system has learned tire pressures with properly
inflated tires, the LOW TIRE light will come on if the
pressure in one tire becomes 12 psi (83 kPa) lower than
the other three tires. The low tire inflation monitor
system won’t alert you if the pressure in more than one
tire is low, if the system is not properly calibrated, or if
the vehicle is moving faster than 60 mph (95 km/h).

The low tire inflation monitor system detects differences
in tire rotation speeds that are caused by changes in 
tire pressure. The system can alert you about a low 
tire 

--

 but it doesn’t replace normal tire maintenance.

See “Tires” in the Index.

When the LOW TIRE light comes on, you should stop
as soon as you can and check all your tires for damage.
(If a tire is flat, see “If a Tire Goes Flat” in the Index.)
Also check the tire pressure in all four tires as soon as
you can. See “Inflation 

-

 Tire Pressure” in the Index.

The light will come on and stay on until you turn off the
ignition or press the RESET button.

Don’t reset the low tire inflation monitor system without
first correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect, the
system will not work properly and may not alert you
when a tire is low.

Any time you adjust a tire’s pressure, rotate your tires,
or have one or more tires repaired or replaced, you’ll
need to reset (calibrate) the low tire inflation monitor
system. You’ll also need to reset the system whenever
you buy new tires and whenever the vehicle’s battery
has been disconnected.
