&Tire care–maintenance and
safety practices.
Check on a daily basis that the
tires are free from serious damage,
nails, and stones. At the same time,
check the tires for abnormal wear.
.
Inspect the tire tread regularly
and replace the tires before their
tread wear indicators become visi-
ble. When a tire’s tread wear in-
dicator becomes visible, the tire is
worn beyond the acceptable limit
and must be replaced immediately.
With a tire in this condition, driving
at even low speeds in wet weather
can cause the vehicle to hydro-
plane. Possible resulting loss of
vehicle control can lead to an
accident.
.
Replace any damaged or un-
evenly worn tires at the time of
rotation. For information about the
tire rotation order, refer to“
Tire
rotation”F11-36.
After tire rotation,
adjust the tire pressures and make
sure the wheel nuts are correctly
tightened. For information aboutthe tightening torque and tighten-
ing sequence for the wheel nuts,
refer to“
Flat tires”F9-5.
&Vehicle load limit–how to
determineThe 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
seating capacity of your vehicle.
The total load capacity includes the
total weight of driver and all pas-
sengers and their belongings, any
cargo, any optional equipment such
as a roof rack or bike carrier, etc.
Therefore cargo capacity can be
calculated by the following method.
Cargo capacity = Load limit(totalweight of occupants + total weight
of optional equipment)
For information about vehicle load-
ing, refer to“
Loading your vehicle”
F8-11.CAUTION
Your vehicle is neither de-
signed nor intended to be
used for trailer towing. There-
fore, never tow a trailer with
your vehicle.

Uniform tire quality grading
standardsThis information indicates the rela-
tive performance of passenger car
tires in the area of treadwear,
traction, and temperature resis-
tance. 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 AThe quality grades apply to new
pneumatic tires for use on passen-
ger cars. However, they do not
apply to deep tread, winter type
snow tires, space-saver or tempor-
ary use spare tires, tires with
nominal rim diameters of 12 inches
or less, or to some limited produc-
tion tires.
All passenger car tires must con-form to Federal Safety Require-
ments in addition to these grades.
&TreadwearThe treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under con-
trolled 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 govern-
ment 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 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 spe-cified 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 characteris-
tics.&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 con-
ditions on a specified indoor labora-
tory 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

(588,1)

grade C corresponds to a level of
performance which all passenger
car tires must meet under the
Federal Motor Vehicle Safety Stan-
dard No. 109. Grades B and A
represent higher levels of perfor-
mance on the laboratory test wheel
than the minimum required by law.
WARNING
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or
in combination, can cause
heat buildup and possible tire
failure.
Reporting safety defects
(U.S.A.)If you believe that your vehicle has
a defect which could cause a crash
or could cause injury or death, you
should immediately inform the Na-
tional Highway Traffic Safety Ad-
ministration (NHTSA) in addition to
notifying Subaru of America, Inc.
If NHTSA receives similar com-
plaints, it may open an investiga-
tion, and if it finds that a safety
defect exists in a group of vehicles,
it may order a recall and remedy
campaign. However, NHTSA can-
not become involved in individual
problems between you, your deal-
er, or Subaru of America, Inc. To
contact NHTSA, you may call the
Vehicle Safety Hotline toll-free at
1-888-327-4236 (TTY: 1-800-424-
9153); go to http://www.safercar.
gov; or write to: Administrator,
NHTSA, 1200 New Jersey Ave-
nue, SE, West Building, Washing-ton, DC 20590. You can also
