Low Tire Pressure Light (If Equipped)
After the system has "learned" tire pressures with
properly inflated tires, the LOW TIRE PRESSURE light
will come on if the pressure in one tire becomes 12 psi
(83 kPa) lower than the other three tires. The tire
pressure monitor system won't alert you if the pressure
in more than one tire is low, if the system is not yet
calibrated, or if the vehicle is moving at less than
15 mph (25 km/h), faster than 75 mph (120 km/h), on
rough roads or during turns. The light may also come on
if you are driving on partially cleared pavement.
The tire pressure
monitor system can
alert you to a large
change in the
pressure in one tire.
When the LOW TIRE PRESSURE 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
the Index.
The light will stay on (while the ignition is on) until you
reset (calibrate) the system. See "Tire Pressure Monitor
System" in the Index.
The LOW TIRE PRESSURE light also comes on briefly
when you turn the ignition key to ON. If the light
doesn't come on then, have it fixed so it will be there to
tell you if the pressure in a tire is low or high.

If the anti lock brake system warning light comes on,
the tire pressure monitor system may not be working.
See your dealer for service. Also, see "Anti
System Warning Light" in the Index.
