Consumer information and Reporting safety defects
Uniform tire quality grading
standardsThis information indicates the relative
performance of passenger car tires in
the area of treadwear, traction, and
temperature resistance. This is to aid
the consumer in making an informed
choice in the purchase of tires.
Quality grades can be found where
applicable on the tire sidewall be-
tween tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Tem-
perature A
The quality grades apply to new
pneumatic tires for use on passenger
cars. However, they do not apply to
deep tread, winter type snow tires,
space-saver or temporary use spare
tires, tires with nominal rim diameters
of 12 inches or less, or to some limited
production tires.
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.
& TreadwearThe 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 (1-1/2) times
as well on the government course as
a tire graded 100. The relative perfor-
mance of tires depends upon the
actual conditions of their use, how-
ever, and may depart significantly
from the norm due to variations in
driving habits, service practices and
differences in road characteristics and
climate.&Traction AA, A, B, CThe traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tire ’s ability to
stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perfor-
mance.
WARNING
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning, or
peak traction characteristics.
& Temperature A, B, CThe 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 condi-
tions on a specified indoor laboratory
test wheel. Sustained high tempera-
ture 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 car tires must
meet under the Federal Motor Vehicle
Safety Standards No. 109. Grades B
and A represent higher levels of
performance on the laboratory test
wheel than the minimum required by

GAS STATION REFERENCE
&
Fuel:
! 2.5-liter non-turbo models
Use only unleaded gasoline with an octane rating of 87 AKI or
higher.
! 2.5-liter turbo models
Use premium unleaded gasoline with an octane rating of 91 AKI
or higher. For temporary purposes if premium unleaded
gasoline is not available, you may use regular unleaded
gasoline with an octane rating of 87 AKI or higher. For optimum
engine performance and driveability, it is required that you use
premium grade unleaded gasoline.
! 3.0-liter models
Use unleaded gasoline with an octane rating of 91 AKI or
higher. Regular unleaded gasoline with an octane rating of 87
AKI or higher may be used. However for optimum engine
performance and driveability, it is recommended that you use
91 AKI or higher grade unleaded gasoline. You may experience
reduced output, poor accelerator response, and reduced fuel
economy when using gasoline with an octane rating lower than
91 AKI, depending on your driving habits and conditions. If you
experience any of these conditions while using a lower octane
rated fuel, you may want to return to using 91 AKI octane rated
fuel as soon as possible. Additionally, if your vehicle knocks
heavily or persistently, or if you are driving with heavy loads
such as when towing a trailer, the use of 91 AKI or higher grade
unleaded gasoline is required.
&
Fuel octane rating
This octane rating is the average of the Research Octane and
Motor Octane numbers and is commonly referred to as the Anti
Knock Index (AKI). Refer to “Fuel”section in this manual.&
Fuel capacity:
16.9 US gal (64 liters, 14.1 Imp gal)&
Engine oil:
Use only API classification SM with the words “ENERGY
CONSERVING ”and the ILSAC certification mark (starburst
mark) displayed on the container.&
Engine oil capacity:
2.5-liter models: 4.2 US qt (4.0 liters, 3.5 Imp qt)
3.0-liter models: 5.8 US qt (5.5 liters, 4.8 Imp qt)
