may occur.
The temporary spare tire is smaller and
lighter than a conventional tire and is
designed for emergency use only. Re-
move the temporary spare tire and re-
install the conventional tire as soon as
possible because the spare tire is de-
signed only for temporary use.
Check the inflation pressure of the tem-
porary spare tire periodically to keep the
tire ready for use. For the correct tire
pressure, refer to“Temporary spare tires”
F12-9.
When using the temporary spare tire, note
the following.
.Drive with caution when temporary
spare tire is fitted. Avoid hard acceleration
and braking, or fast cornering, as control of
the vehicle may be lost.
.Do not exceed 50 mph (80 km/h).
.Do not put a tire chain on the temporary
spare tire. Because of the smaller tire size,
a tire chain will not fit properly.
.Do not use two or more temporary
spare tires at the same time.
.Do not drive over obstacles. This tire
has a smaller diameter, so road clearance
is reduced.
1) Tread wear indicator bar
2) Indicator location mark.When the wear indicator appears on
the tread, replace the tire.
.The temporary spare tire must be used
only on a rear wheel. If a front wheel tire
gets punctured, replace the wheel with a
rear wheel and install the temporary spare
tire in place of the removed rear wheel.
.Always set the driver’s control center
differential to the manual mode and adjust
the initial LSD torque to the minimum.

tighten the wheel nuts to the specified
torque, following the tightening order in the
illustration.
For the wheel nut tightening torque, refer
to“Tires”F12-8. Never use your foot on
the wheel nut wrench or a pipe extension
on the wrench because you may exceed
the specified torque. Have the wheel nut
torque checked at the nearest automotive
service facility.
Except STI15. Store the flat tire in the spare tire
compartment. For except STI models, put
in the spacer and tighten the attaching bolt
firmly.
Also store the jack, jack handle and wheel
nut wrench in their storage locations.
WARNING
.Never place a tire or tire changing
tools in the passenger compart-
ment after changing wheels. In a
sudden stop or collision, loose
equipment could strike occu-
pants and cause injury. Store
the tire and all tools in the proper
place..When you store a flat tire, be sure
to set the rear seatback to the
upright position. If you fold down
the seatback, an accident or
injury may occur when the flat
tire suddenly moves.
&Sealing flat tire (models with
flat tire repair kit)
WARNING
Read these instructions and
warnings carefully before sealing a
flat tire.
Compliance with these instructions
is vital to ensuring vehicle safety.
Noncompliance with these instruc-
tions means risking tire damage,
which can affect vehicle handling
and lead to loss of vehicle control.
This may result in serious injury or
death.
If the tire is punctured, you can seal the flat
tire temporarily by using the flat tire repair
kit. You can seal a flat tire caused, for

WARNING
.When replacing or installing
tire(s), all four tires must be the
same for the following items.
(a) Size
(b) Circumference
(c) Speed symbol
(d) Load index
(e) Construction
(f) Manufacturer
(g) Brand (tread pattern)
(h) Degrees of wear
For items (a) to (d), you must
obey the specification that is
printed on the tire placard. The
tire placard is located on the
driver’s door pillar.
If all four tires are not the same in
items (a) to (h), there is a possi-
bility that it may lead to serious
mechanical damage to the drive
train of your car and affect the
following factors.
—Ride
—Handling
—Braking—Speedometer/Odometer
calibration
—Clearance between the body
and the tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
.Use only radial tires. Do not use
radial tires together with belted
bias tires and/or bias-ply tires.
Doing so can dangerously re-
duce controllability, resulting in
an accident.
&Wheel replacementWhen replacing wheels due, for example,
to damage, make sure the replacement
wheels match the specifications of the
wheels that are fitted as standard equip-
ment. Replacement wheels are available
from SUBARU dealers.
WARNING
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could
interfere with brake caliper opera-
tion and may cause the tires to rub
against the wheel well housing dur-ing turns. The resulting loss of
vehicle control could lead to an
accident.
NOTEWhen any of the wheels are removed
and replaced for tire rotation or to
change a flat tire, always check the
tightness of the wheel nuts after driving
approximately 600 miles (1,000 km). If
any nut is loose, tighten it to the
specified torque.

&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.
