If you park your vehicle in
case of an emergency
The hazard warning flasher should be
used in day or night to warn other drivers
when you have to park your vehicle under
emergency conditions.
Avoid stopping on the road. It is best to
safely pull off the road if a problem occurs.
The hazard warning flasher can be acti-
vated regardless of the ignition switchposition.
Turn on the hazard warning by pushing
the hazard warning flasher switch. Turn it
off by pushing the switch again.NOTE
When the hazard warning flasher is on,
the turn signals do not work.
Temporary spare tire
WARNING
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the tire pressure monitoring system
(TPMS) is unable to monitor all four
road wheels. Contact your SUBARU
dealer as soon as possible for tire
and sensor replacement and/or sys-
tem resetting.
CAUTION
Never use any temporary spare tire
other than the original. Using other
sizes may result in severe mechan-
ical damage to the drive train of yourvehicle.
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. The correct pressure is
60 psi (420 kPa, 4.2 kg/cm
2).
When using the temporary spare tire, note
the following. . 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. Maintenance tools
Your vehicle is equipped with the following
maintenance tools. .

CAUTION
. Be careful not to damage brake
hoses, sensor harnesses, and
other parts when washing sus-
pension components.
. Be careful not to flush the engine
bottom for a long time. It may
cause damage of some electricalparts.
! Using a warm water washer
. Keep a good distance of 12 in (30 cm)
or more between the washer nozzle and
the vehicle. . Do not wash the same area continu-
ously.. If a stain will not come out easily, wash
by hand. Some warm water washers are
of the high temperature, high pressure
type, and they can damage or deform the
resin parts such as moldings, or cause
water to leak into the vehicle.
& Waxing and polishing
Always wash and dry the vehicle before
waxing and polishing.
Use a good quality polish and wax and
apply them according to the manufac-turer ’s instructions. Wax or polish when
the painted surface is cool. Be sure to polish and wax the chrome trim,
as well as the painted surfaces. Loss of
wax on a painted surface leads to loss of
the original luster and also quickens the
deterioration of the surface. It is recom-
mended that a coat of wax be applied at
least once a month, or whenever the
surface no longer repels water.
If the appearance of the paint has dimin-
ished to the point where the luster or tone
cannot be restored, lightly polish the
surface with a fine-grained compound.
Never polish just the affected area, but
include the surrounding area as well.
Always polish in only one direction. A
No. 2000 grain compound is recom-
mended. Never use a coarse-grained
compound. Coarse-grained compounds
have a smaller grain-size number and
could damage the paint. After polishing
with a compound, coat with wax to restore
the original luster. Frequent polishing with
acompoundoranincorrectpolishing
technique will result in removing the paint
layer and exposing the undercoat. When
in doubt, it is always best to contact your
SUBARU dealer or an auto paint specia-list.
CAUTION
Do not use any agents with organic solvents on the surface of the bulb
assembly cover. However, if a polish
or wax with organic solvents is
applied to the cover surface, com-
pletely wipe off the polish or wax.
Otherwise, the cover surface may bedamaged.
NOTE
Be careful not to block the windshield
washer nozzles with wax when waxing
the vehicle. & Cleaning aluminum wheels
. Promptly wipe the aluminum wheels
clean of any kind of grime or agent. If dirt
is left on too long, it may be difficult to
clean off. . Do not use soap containing grit to
clean the wheels. Be sure to use a neutral
cleaning agent, and later rinse thoroughly
with water. Do not clean the wheels with a
stiff brush or expose them to a high-speed
washing device. . Clean the vehicle (including the alumi-
num wheels) with water as soon as
possible when it has been splashed with
sea water, exposed to sea breezes, or
driven on roads treated with salt or otheragents.

Tires and wheels &Types of tires
You should be familiar with type of tires
present on your vehicle. ! All season tires
All season tires are designed to provide
an adequate measure of traction, handling
and braking performance in year-round
driving including snowy and icy road
conditions. However all season tires do
not offer as much traction performance as
winter (snow) tires in heavy or loose snow
or on icy roads.
All season tires are identified by “ALL
SEASON ”and/or “M+S ”(Mud & Snow) on
the tire sidewall. ! Summer tires
Summer tires are high-speed capability
tires best suited for highway driving under
dry conditions.
Summer tires are inadequate for driving
on slippery roads such as on snow-
covered or icy roads.
If you drive your vehicle on snow-covered
or icy roads, we strongly recommend the
use of winter (snow) tires.
When installing winter tires, be sure to
replace all four tires. !
Winter (snow) tires
Winter tires are best suited for driving on
snow-covered and icy roads. However
winter tires do not perform as well as
summer tires and all season tires on roads
other than snow-covered and icy roads.
& Tire pressure monitoring
system (TPMS) (if equipped)
The tire pressure monitoring system pro-
vides the driver with a warning message
by sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low. The tire pressure monitor-
ing system will activate only when the
vehicle is driven. Also, this system may
not react immediately to a sudden drop in
tire pressure (for example, a blow-out
caused by running over a sharp object).
If you adjust the tire pressures in a warm
garage and will then drive the vehicle in
cold outside air, the resulting drop in tire
pressures may cause the low tire pressure
warning light to illuminate. To avoid this
problem when adjusting the tire pressures
in a warm garage, inflate the tires to
pressures higher than those shown on the
tire placard. Specifically, inflate them by an
extra 1 psi (6.9 kPa, 0.07 kgf/cm
2) for
every difference of 10 8F (5.6 8C) between
the temperature in the garage and the temperature outside. By way of example,
the following table shows the required tire
pressures that correspond to various out-
side temperatures when the temperature
in the garage is 60
8F (15.6 8C).
Example:
Tire size: P205/55R16 89V and
P205/50R17 88V
Standard tire pressures:
Front: 33 psi (230 kPa, 2.3 kgf/cm
2)
Rear: 32 psi (220 kPa, 2.2 kgf/cm2)
Garage temperature: 60 8F (15.6 8C)
Outside

(255, 2.55)
10 8F( 23 8C) 40 (280, 2.8) 39 (270, 2.7)
If the low tire pressure warning light
illuminates when you drive the vehicle in
cold outside air after adjusting the tire
pressures in a warm garage, re-adjust the
tire pressures using the method described
above. Then, increase the vehicle speed
to at least 20 mph (32 km/h) and check to
see that the low tire pressure warning light
turns off a few minutes later. If the low tire
pressure warning light does not turn off,

&Tire rotation direction mark
Example of tire rotation direction mark
1) Front
If the tire has the rotation direction
specification, the tire rotation direction
mark is placed on its sidewall.
When you install a tire that has the tire
rotation direction mark, install the tire with
the direction mark facing forward. &
Tire rotationVehicles equipped with 4 non-unidirec-
tional tires
1) Front
Vehicles equipped with unidirectional tires
1) Front Tire wear varies from wheel to wheel. 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). Move the tires to the positions shown
intheillustrationeachtimetheyarerotated.
Replace any damaged or unevenly worn
tires at the time of rotation. After tire
rotation, adjust the tires pressures and
make sure the wheel nuts are correctlytightened.
After driving approximately 600 miles
(1,000 km), check the wheel nuts again
and retighten any nut that has becomeloose. &
Tire replacement
The wheels and tires are important and
integral parts of your vehicle ’s design;
they cannot be changed arbitrarily. The
tires fitted as standard equipment are
optimally matched to the characteristics
of the vehicle and were selected to give
the best possible combination of running
performance, ride comfort, and service
life. It is essential for every tire to have a
size and construction matching those
shown on the tire placard and to have a
speed symbol and load index matching
those shown on the tire placard.

11-30Maintenance and service/Tires and wheels
Using tires of a non-specified size detracts
from controllability, ride comfort, braking
performance, speedometer accuracy and
odometer accuracy. It also creates incor-
rect body-to-tire clearances and inappro-
priately changes the vehicle’sground
clearance.
All four tires must be the same in terms of
size, circumference, speed symbol, load
index, construction, manufacturer, brand
(tread pattern), and degrees of wear. You
are advised to replace the tires with new
ones that are identical to those fitted as
standard equipment.
For safe vehicle operation, SUBARU
recommends replacing all four tires at
the same time.
WARNING
. When you replacing or installing
tire(s), all four tires must be the
same for 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 the items (a) to (d), you must
obey the specification that is
printed on the tire placard. The
tire placard is located on the
bottom of driver
’s door pillar.
If all of four tires are not the same
for items (a) to (h), there is a
possibility that serious mechan-
ical damage could occur to the
drive train of your car, and affect
the following. — Ride
— Handling
— Braking
— Speedometer/Odometer
calibration— Clearance between the body
and 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 replacement
When 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 anaccident.
NOTE
When 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 driv-
ing approximately 600 miles (1,000 km).
If any nut is loose, tighten it to the
specified torque.
