After a tire rotation is completed, as shown
below, the system can auto learn the loca -
tions of each sensor ID. Auto learning/local -
ization occurs when the vehicle ignition
status is changed from Off to On and speeds
of greater than 5 mph (8 km/h) are obtained and remain over 5 mph (8 km/h) for at about
a 15 minute period. You may need to drive
for 20 minutes to account slower speeds and
stops.
If the tires are rotated incorrectly, the Auto
localization of the TPIS sensors will fail to
locate correctly resulting in incorrect loca -
tions for the pressure values displayed in the
Instrument Cluster.
DEPARTMENT OF TRANSPORTATION
UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by the
tire's manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform
to Federal safety requirements in addi -
tion to these grades.
Treadwear
The Treadwear grade is a comparative
rating, based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one and one-half times as well on
the government course as a tire graded
100. The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to varia -
tions in driving habits, service practices,
and differences in road characteristics
and climate.
Traction Grades
The Traction grades, from highest to
lowest, are AA, A, B, and C. These grades
represent the tire's ability to stop on wet
pavement, as measured under
controlled conditions on specified
government test surfaces of asphalt and
concrete. A tire marked C may have poor
traction performance.
CAUTION!
4500/5500 Dual Rear Tires may only have
one approved direction of rotation. This is
to accommodate the asymmetrical design
(tread pattern) of the On/Off road tire.
When replacing a flat, the spare tire may
have to be remounted on the rim or
installed at a different location to maintain
the correct placement of the tire on the
wheel relative to the tire/wheel position on
the vehicle. For example, if the spare is
used to replace an outer rear tire it will have
to be remounted on the rim so that the
wheel is dished inward. That way the tread
design of asymmetrical tires will maintain
proper position.
CAUTION! (Continued)

Temperature Grades
The Temperature grades are A (the
highest), B, and C, representing the tire's
resistance to the generation of heat and
its ability to dissipate heat, when tested
under controlled conditions on a speci -
fied indoor laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance, which all
passenger vehicle tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A repre -sent higher levels of performance on the
laboratory test wheel, than the minimum
required by law.
STORING THE VEHICLE
If you are storing your vehicle for more than 21
days, we recommend that you take the following
steps to minimize the drain on your vehicle's
battery:
Disconnect the negative cable from battery.
Any time you store your vehicle or keep it out
of service (i.e., vacation) for two weeks or
more, run the air conditioning system at idle
for about five minutes in the fresh air and
high blower setting. This will ensure
adequate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
BODYWORK
Protection From Atmospheric Agents
Vehicle body care requirements vary according
to geographic locations and usage. Chemicals
that make roads passable in snow and ice and
those that are sprayed on trees and road
surfaces during other seasons are highly corro
-
sive to the metal in your vehicle. Outside
parking, which exposes your vehicle to airborne
contaminants, road surfaces on which the
vehicle is operated, extreme hot or cold weather
and other extreme conditions will have an
adverse effect on paint, metal trim, and under -
body protection.
The following maintenance recommendations
will enable you to obtain maximum benefit from
the corrosion resistance built into your vehicle.
WARNING!
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
WARNING!
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
under-inflation, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.

398TECHNICAL SPECIFICATIONS
Torque Specifications
**Use only authorized dealer recommended
lug nuts/bolts and clean or remove any dirt or
oil before tightening.
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
NOTE:
Dual wheels are flat mounted, center piloted.
The lug nuts are a two-piece assembly. When
the tires are being rotated or replaced, clean
these lug nuts and add two drops of oil at the interface between the hex and the washer.
Ensure that the socket is fully engaged on the
lug nut/bolt (do not insert it half way).

Oil Interface Location

Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.

Wheel Mounting Surface
Retighten the wheel nuts in the same sequence
to the torques listed in the table. Go through the
sequence a second time to verify that specific
torque has been achieved. Retighten to specifi
-
cations after 25 miles (40 km) and check the
lug nut/bolt torque to be sure that all the lug
nuts/bolts are properly seated against the
wheel.

8/10 Lug Nuts/Bolts Torque Patterns

It is recommended that wheel stud nuts be kept
torqued to specifications at all times. Torque
wheel stud nuts to specifications at each lubri -
cation interval.
