&Engine coolant
! Checking the coolant level
Check the coolant level at each fuel stop.
1. Check the coolant level on the outside
of the reservoir while the engine is cool.
2. If the level is close to or lower than the “LOW ”level mark, add coolant up to the
“ FULL ”level mark. If the reserve tank is
empty, remove the radiator cap and refill
as required.
3. After refilling the reserve tank and the
radiator, reinstall the caps and check that
the rubber gaskets inside the radiator cap
are in the proper position.
CAUTION
. Be careful not to spill engine
coolant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on
the exhaust pipe, be sure to wipe
it off.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface. !
Changing the coolant
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down
completely. Since the coolant is
under pressure, you may suffer
serious burns from a spray of boil-
ing hot coolant when the cap isremoved.
Always add genuine SUBARU cooling
system conditioner whenever the coolant
is replaced.
Change the engine coolant and add
genuine SUBARU cooling system condi-
tioner using the following procedures
according to the maintenance schedule
in the “Warranty and Maintenance Book-
let ”.

mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting. If the light
illuminates steadily after blinking
for approximately one minute,
promptly contact a SUBARU dealer
to have the system inspected.
& Tire inspection
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.
Contact your SUBARU dealer immedi-
ately if you find any problem. NOTE . When the wheels and tires strike
curbs or are subjected to harsh treat-
ment as when the vehicle is driven on a
rough surface, they can suffer damage
that cannot be seen with the naked eye.
This type of damage does not become
evident until time has passed. Try not
to drive over curbs, potholes or on
other rough surfaces. If doing so is
unavoidable, keep the vehicle ’s speed
down to a walking pace or less, and approach the curbs as squarely as
possible. Also, make sure the tires are
not pressed against the curb when you
park the vehicle..
If you feel unusual vibration while
driving or find it difficult to steer the
vehicle in a straight line, one of the
tires and/or wheels may be damaged.
Drive slowly to the nearest authorized
SUBARU dealer and have the vehicleinspected.
& Tire pressures and wear
Maintaining the correct tire pressures
helps to maximize the tires ’service lives
and is essential for good running perfor-
mance. Check and, if necessary, adjust
the pressure of each tire (including the
spare) at least once a month (for example,
during a fuel stop) 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 values shown on
the tire placard. The tire placard is located
on the door pillar on the driver ’s side.
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 outdoors before driving thevehicle.
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 itspressure. Maintenance and service

11-38Maintenance and service
NOTE .The air pressure in a tire increases
by approximately 4.3 psi (30 kPa, 0.3 kgf/cm
2) when the tire becomes warm.
. The tires are considered cold when
the vehicle has been parked for at least
3 hours or has been driven less than 1
mile (1.6 km).
WARNING
Do not let air out of warm tires to
adjust pressure. Doing so will result
in low tire pressure.
Incorrect tire pressures detract from con-
trollability and ride comfort, and they
cause the tires to wear abnormally. .
Correct tire pressure (tread worn
evenly)
Roadholding is good, and steering is
responsive. Rolling resistance is low, so
fuel consumption is also lower. .
Abnormally low tire pressure (tread
worn at shoulders)Rolling resistance is high, so fuel con-
sumption is also higher.

&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,
power windows, power seats, radio,
and heater, to the extent that these
items are available as factory-in-
stalled equipment (whether in-
stalled or not). . Bead
The part of the tire that is made of
steel wires, wrapped or reinforced
by ply cords and that is shaped to fit
the rim. . Bead separation
A breakdown of the bond between
components in the bead. . Bias ply tire
A pneumatic tire in which the ply
cords that extend to the beads are
laid at alternate angles substantially
less than 90 degrees to the center-
line of the tread. . Carcass
The tire structure, except tread and sidewall rubber which, when in-
flated, bears the load.
. Chunking
The breaking away of pieces of the
tread or sidewall. . Cold tire pressure
The pressure in a tire that has been
driven less than 1 mile or has been
standing for three hours or more. . Cord
The strands forming the plies in the tire. . Cord separation
The parting of cords from adjacent
rubber compounds. . Cracking
Any parting within the tread, side-
wall, or inner liner of the tire
extending to cord material. . Curb weight
The weight of a motor vehicle with
standard equipment including the
maximum capacity of fuel, oil and
coolant, and if so equipped, air
conditioning and additional weight
optional engine. .
Extra load tire
A tire designed to operate at higher
loads and higher inflation pressure
than the corresponding standardtire. . Groove
The space between two adjacent
tread ribs. . Innerliner
The layer(s) forming the inside sur-
face of a tubeless tire that contains
the inflating medium within the tire. . Innerliner separation
The parting of the innerliner from
cord material in the carcass. . Intended outboard sidewall
(1) The sidewall that contains a
whitewall, bears white lettering
or bears manufacturer, brand,
and/or model name molding that
is higher or deeper than the
same molding on the other side-
wall of the tire, or (2) The outward facing sidewall
of an asymmetrical tire that has
a particular side that must al-
ways face outward when mount-
