How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are
properly in ated simply by looking at them. Radial
tires may look properly in ated even when they
are under-in ated. Check the tire’s in ation
pressure when the tires are cold. Cold means your
vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to
get a pressure measurement. If the cold tire
in ation pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
in ation pressure is low, add air until you reach the
recommended amount.
If you over ll the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re-check the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Pressure Monitor System
Your vehicle has a Tire Pressure Monitor System
(TPMS). This feature is designed to alert you
when the system detects a large change in the
pressure of one tire. The system cannot alert you
before you drive that a tire is low or at. You
must begin driving before the system works
properly. The TPMS works with the brake control
system and is designed to detect differences
in the tire rotation speeds that are caused
by changes in tire pressure. The TPMS does not
replace normal tire maintenance, seeTires on
page 322,Tire Inspection and Rotation on
page 333andWhen It Is Time for New Tires on
page 335.

This light, on the
instrument panel cluster,
comes on when the
tire pressure monitoring
system detects a
low-tire condition.
This light also comes on for a few seconds and
then go off when you turn the ignition to ON. This
indicates that the TPMS is functioning properly.
If the low-tire pressure warning light comes
on while driving your vehicle, the system may
have detected a low-tire condition. You need to
stop as soon as possible and check your tires
for damage. If a tire is at, seeIf a Tire Goes Flat
on page 342andChanging a Flat Tire on
page 343. Also check the tire pressure in all four
tires, and set them to the speci ed level shown
on the Tire and Loading Information label.SeeIn ation - Tire Pressure on page 329and
Loading Your Vehicle on page 253for additional
information.
Note:The tire pressure monitoring system on your
vehicle warns you when one of the tires is
signi cantly under-in ated and when some
combinations of the tires are signi cantly
under-in ated. However, there are other
combinations of signi cantly under-in ated tires for
which the tire pressure monitoring system might not
give a warning. These other combinations are
relatively common, accounting for approximately
half the instances in which vehicles have
signi cantly under-in ated tires. For example, the
system might not warn you when both tires on the
same side or on the same axle of your vehicle are
signi cantly under-in ated. It is particularly
important, therefore, to check the tire pressure in all
of the tires regularly and maintain proper pressure.
In order for the tire pressure monitoring system to
work properly you need to reset (initialize) the
tire pressure monitoring system. Any time
you check and/or adjust a tire’s pressure, repair or
replace a tire or wheel, or rotate the tires the
tire pressure monitor system needs to be reset.
