How to Check

Usea good quality pocket-type gage to check tire
pressure.You cannot tell if your tires are properly inflated
simplyby looking at them. Radial tires may look properly
inflatedeven when they are under-inflated. Check the
tire’sinflation pressure when the tires are cold. Cold
meansyour vehicle has been sitting for at least
threehours or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem. Press
the tire gage firmly onto the valve to get a pressure
measurement. If the cold tire inflation pressure matches
the recommended pressure on the Tire and Loading
Information label, no further adjustment is necessary. If
the inflation pressure is low, add air until you reach
the recommended amount.
If you overfill 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.
Besure to put the valve caps back on the valve stems.
Theyhelp prevent leaks by keeping out dirt and moisture.
Tire Pressure Monitor System
If your vehicle has the tire pressure monitor system, it
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 90minutes
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 PRESSURE
message will come on if the pressure in one tire
becomes 12psi (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 faster than 70mph (110 km/h).
