Tire Pressure Monitor System (If Equipped) The tire pressure 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 reset. 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 properly 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 or on gravel roads. The tire pressure 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. 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-Lock Brake System Warning Light" in the Index. 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 - Tire Pressure" in the Index. The light will come on and stay on, when the ignition is ON, until the tire pressure condition is corrected and you RESET the system. The light may come on and then go out when driving on partially cleared pavement or on gravel roads. Under these conditions, you do not need to reset the tire pressure monitor. 6-42

Tire Pressure Monitor System (If Equipped)
The tire pressure 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 reset.
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 properly
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 or on
gravel roads.
The tire pressure 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.
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
-
Lock Brake
System Warning Light” in the Index.
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
-
Tire Pressure” in
the Index.
The light will come on and stay on, when the ignition is
ON, until the tire pressure condition is corrected and
you RESET the system. The light may come on and then
go out when driving on partially cleared pavement or on
gravel roads. Under these conditions, you do not need to
reset the tire pressure monitor.
