When the CHECK TIRE PRESSURE message appears
on the Driver Information Center or the systems monitor

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.
Any time you adjust a tire’s pressure or have one or
more tires repaired or replaced, you’ll need to reset
(calibrate) the check tire pressure system. You’ll also
need to reset the system whenever you rotate the tires,
buy new tires and install or remove the compact spare.
Don’t reset the check tire pressure 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 check
tire pressure system will not work properly and may not
alert you when a tire is low or high.
