You will hear three chimes, then the LOW TIRE
PRESSURE message will go off and the DIC will return
to TIRE PRESSURE NORMAL. If the LOW TIRE
PRESSURE message comes back on, the check tire
pressure system has not reset. Repeat the procedure.
The system completes the calibration process during
driving. The system learns the pressure at each tire
throughout the operating speed range of your vehicle.
The system normally takes between 30 and 60 minutes of
driving to learn the tire pressures. The system normally
takes 10 to 20 minutes of driving in each speed range to
learn tire pressures. The speed ranges are 20 to 40 mph
(32 to 64 km/h), 40 to 60 mph (64 to 96 km/h), and above
60 mph (96 km/h). This time may be longer depending on
your individual driving habits. The learning process does
not need to be completed during a single trip. Once
learned, the system will remember the tire pressure until
the system is reset.Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. SeeWhen It Is Time
for New Tires on page 5-69andWheel Replacement
on page 5-72for more information.
Make sure the spare tire is stored securely. Push, pull,
and then try to rotate or turn the tire, If it moves,
use the folding wrench to tighten the cable. See “Storing
a Flat or Spare Tire and Tools” inChanging a Flat
Tire on page 5-77.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The rst rotation
is the most important. SeeScheduled Maintenance
on page 6-4, for scheduled rotation intervals.

Storing a Flat or Spare Tire and Tools
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision,
loose equipment could strike someone. Store
all these in the proper place.
{CAUTION:
The underbody-mounted spare tire needs to be
stored with the valve stem pointing down. If
the spare tire is stored with the valve stem
pointing upwards, its secondary latch won’t
work properly and the spare tire could loosen
and suddenly fall from your vehicle. If this
happened when your vehicle was being driven,
the tire might contact a person or another
vehicle, causing injury and, of course, damage
to itself as well. Be sure the
underbody-mounted spare tire is stored with
its valve stem pointing down.
