cation and a tightening sequence
specification for the wheel nuts can
be found “Flat tires ”section in chapter
9. & Vehicle load limit –how to
determine
The load capacity of your vehicle is
determined by weight, not by avail-
able cargo space. The load limit of
your vehicle is shown on the vehicle
placard attached to the driver ’s side
B-pillar. Locate the statement “The
combined weight of occupants and
cargo should never exceed XXX kg or
XXX lbs ”on your vehicle ’s placard.
The vehicle placard also shows seat-
ing capacity of your vehicle.
The total load capacity includes the
total weight of driver and all passen-
gers and their belongings, any cargo,
any optional equipment such as a
trailer hitch, roof rack or bike carrier,
etc., and the tongue load of a trailer.
Therefore cargo capacity can be
calculated by the following method.
Cargo capacity = Load limit (total
weight of occupants + total weight of optional equipment + tongue load of a
trailer (if applicable))
For towing capacity information and
weight limits, refer to
“Trailer towing ”
section in chapter 8. ! Calculating total and load ca-
pacities varying seating con-
figurations
Calculate the available load capacity
as shown in the following examples:
Example 1A
Vehicle capacity weight of the vehicle
is 900 lbs (408 kg), which is indicated
on the vehicle placard with the state-ment “The combined weight of occu-
pants and cargo should never exceed 900 lbs or 408 kg
”.
For example, if the vehicle has one
occupant weighing 154 lbs (70 kg)
plus cargo weighing 662 lbs (300 kg).
1. Calculate the total weight.
2. Calculate the available load capa-
city by subtracting the total weight
from the vehicle capacity weight of
900 lbs (408 kg).
3. The result of step 2 shows that a
further 84 lbs (38 kg) of cargo can be
carried.

13-12Consumer information and Reporting safety defects
Uniform tire quality grading standards
This 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. &
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 (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, C
The 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, C
The temperature grades are A (the
highest), B, and C, representing thetire ’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. ! WRX
Use premium unleaded gasoline with an octane rating of 91 AKI
or higher. If premium unleaded gasoline with an octane rating of
91 AKI is not available, regular unleaded gasoline with octane
rating of 87 AKI or higher may be temporarily used. For
optimum engine performance and driveability, it is required that
you use premium grade unleaded gasoline with an octane
rating of 91 AKI or higher. ! WRX-STI
Use super-premium unleaded gasoline with an octane rating of
93 AKI or higher. If super-premium unleaded gasoline with an
octane rating of 93 AKI is not available, premium unleaded
gasoline with octane rating of 91 AKI or higher may be
temporarily used. For optimum engine performance and driveability, it is required that you use super-premium grade
unleaded gasoline with an octane rating of 93 AKI or higher.
