crease in temperature could cause
tread separation, and failure of the
tire(s). Possible resulting loss of
vehicle control could lead to an
accident.! Measuring and adjusting air
pressure to achieve proper in-
flationCheck and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and
before any long journey. Check the
tire pressures when the tires are
cold. Use a pressure gauge to
adjust the tire pressures to the
specific values. Driving even a
short distance warms up the tires
and increases the tire pressures.
Also, the tire pressures are affected
by the outside temperature. It is
best to check tire pressure out-
doors before driving the vehicle.
When a tire becomes warm, the air
inside it expands, causing the tire
pressure to increase. Be careful not
to mistakenly release air from a
warm tire to reduce its pressure.
&Glossary of tire terminology.
Accessory weight
The combined weight (in excess of
those standard items which may be
replaced) of automatic transmis-
sion, power steering, power brakes,

& 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 ’streadwear
indicator 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
vehiclecontrolcanleadtoan
accident.
.
To maximize the life of each tire
and ensure that the tires wear
uniformly, it is best to rotate the
tires every 7,500 miles (12,000 km).
For information about the tire rota-
tion order, refer to “Tire rotation ”
F 11-29
.Replace any damaged or
unevenly worn tires at the time of rotation. After tire rotation, adjust
the tire pressures and make sure
the wheel nuts are correctly tigh-
tened. For information about the
tightening torque and tightening
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.
Thevehicleplacardalsoshows
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 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 information about vehicle load-
ing, refer to “Loading your vehicle ”
F 8-10
.
NOTEYour vehicle is neither designed
nor intended to be used for
trailer towing. Therefore, never
tow a trailer with your vehicle.

Example 2BFor example, if a person weighing
143 lbs (65 kg) and a child weighing
40 lbs (18 kg) now enter the same
vehicle (bringing the number of
occupants to three), and a child
restraint system weighing 11 lbs (5
kg) is installed in the vehicle for the
child to use, the calculations are as
follows.1.
Calculate the total weight.
2.
Calculate the available load ca-
pacity.
3.
The total weight now exceeds
the capacity weight by 32 lbs (15
kg), so the cargo weight must be
reduced by 32 lbs (15 kg) or more.
NOTEYour vehicle is neither designed
nor intended to be used for
trailer towing. Therefore, never
tow a trailer with your vehicle.& Determining compatibility of
tire and vehicle load capaci-
tiesThe sum of four tires ’maximum
load ratings must exceed the max-
imum loaded vehicle weight
( “GVWR ”). In addition, sum of the
maximum load ratings of two front
tires and of two rear tires must
exceed each axle ’smaximum
loaded capacity ( “GAWR ”). Original
equipment tires are designed to
fulfill those conditions.
The maximum loaded vehicle
weight is referred to Gross Vehicle
Weight Rating (GVWR). And each
axle ’s maximum loaded capacity is
referred to Gross Axle Weight Rat-
ing (GAWR). The GVWR and each
axle ’s GAWR are shown on the
vehicle certification label affixed to
the driver ’s door.

Consumer information and Reporting safety defects
The GVWR and front and rear
GAWRs are determined by not only
the maximum load rating of tires but
also loaded capacities of the vehi-
cle ’s suspension, axles and other
parts of the body.
Therefore, this means that the
vehicle cannot necessarily be
loaded up to the tire ’s maximum
load rating on the tire sidewall.& Adverse safety conse-
quences of overloading on
handling and stopping and
on tiresOverloading could affect vehicle
handling, stopping distance, and
vehicle and tire performance in the
following ways. This could lead to
an accident and possibly result in
severe personal injury..
Vehicle stability will deteriorate.
.
Heavy and/or high-mounted
loads could increase the risk of
rollover.
.
Stopping distance will increase.
.
Brakes could overheat and fail.
.
Suspension, bearings, axles and
other body parts could break or
experience accelerated wear that
will shorten vehicle life.
.
Tires could fail.
.
Tread separation could occur.
.
Tire could separate from its rim.
& Steps for Determining Cor-
rect Load Limit1.
Locate the statement “The com-
bined weight of occupants and
cargo should never exceed XXX
kg or XXX lbs. ”on your vehicle ’s
placard.
2.
Determine the combined weight
of the driver and passengers that
will be riding in your vehicle.
3.
Subtract the combined weight of
the driver and passengers from
XXX kg or XXX lbs.
4.
The resulting figure equals the
available amount of cargo and
luggage load capacity. For exam-
ple, if the “XXX ”amount equals
1,400 lbs (635 kg) and there will be
five- 150 lbs (68 kg) passengers in your vehicle, the amount of avail-
able cargo and luggage load capa-
city is 650 lbs. (1,400
750 (5 6
150) = 650 lbs)
5.
Determine the combined weight
of luggage and cargo being loaded
on the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calcu-
lated in Step 4.
6.
If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and
luggage load capacity of your ve-
hicle.
NOTEYour vehicle is neither designed
nor intended to be used for
trailer towing. Therefore, 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 maxi-
mum 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 accel-
eration, cornering, hydroplan-
ing, or peak traction charac-
teristics.&
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

Consumer information and Reporting safety defects
grade C corresponds to a level of
performance which all passenger
car tires must meet under the
Federal Motor Vehicle Safety Stan-
dards 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 ex-
cessive loading, either sepa-
rately or in combination, can
cause heat buildup and possi-
ble 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 in-
form the National Highway Traffic
Safety Administration (NHTSA) in
addition to notifying Subaru of
America, Inc.

plaints, it may open an investiga-
tion, and if it finds that a safety
defect exists in a group of vehi-
cles, it may order a recall and
remedy campaign. However,
NHTSA cannot become involved
in individual problems between
you, your dealer, or Subaru of
America, Inc. To contact NHTSA,
you may call the Vehicle Safety
Hotline toll-free at 1-888-327-4236
