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 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 recalibrated.
After the system has learned tire pressures with
properly inated tires, the LOW TIRE PRESSURE
message 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 faster than 70 mph (110 km/h).
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. SeeTires on page 5-60.When the LOW TIRE PRESSURE message comes on,
you should stop as soon as you can and check all
your tires for damage. (If a tire is at, seeIf a Tire Goes
Flat on page 5-77.) Also check the tire pressure in all
four tires as soon as you can. SeeInation - Tire
Pressure on page 5-66.
The LOW TIRE PRESSURE message will also be
displayed (while the ignition is on) until you reset
(calibrate) the system.
Don’t reset the tire pressure monitor system without rst
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 system will not work properly and may not alert you
when a tire is low.
Any time you adjust a tire’s pressure, rotate your tires,
or have one or more tires repaired or replaced, you’ll
need to reset (calibrate) the tire pressure monitor
system. You’ll also need to reset the system whenever
you buy new tires and whenever the vehicle’s battery
has been disconnected.

Underhood Fuse Block
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses. This greatly
reduces the chance of res caused by electrical
problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
