(5.6°C) between the temperature in the
garage and the temperature outside. By
way of example, the following table shows
the required tire pressures that corre-
spond to various outside temperatures
when the temperature in the garage is
60°F (15.6°C).
Example:
Tire size: 215/40R18 85Y
Standard tire pressures:
Front: 35 psi (240 kPa, 2.4 kgf/cm
2)
Rear: 35 psi (240 kPa, 2.4 kgf/cm2)
Garage temperature: 60°F (15.6°C)
Example:
Tire size: 215/45R17 87W
Standard tire pressures:
Front: 35 psi (240 kPa, 2.4 kgf/cm2)
Rear: 35 psi (240 kPa, 2.4 kgf/cm2)
Garage temperature: 60°F (15.6°C) If the low tire pressure warning light illumi-
nates when you drive the vehicle in cold

outside air after adjusting the tire pres-
sures in a warm garage, re-adjust the tire
pressures using the method described
above. Then, increase the vehicle speed
to at least 25mph (40km/h) and check to
see that the low tire pressure warning light
goes off a few minutes later. If the low tire
pressure warning light does not go off, the
tire pressure monito ring system may not
be functioning normally. In this event, go
to a SUBARU dealer to have the system
inspected as soon as possible.
While the vehicle is driven, friction
between tires and the road surface
causes the tires to warm up. After illumi-
nation of the low tire pressure warning
light, any increase in the tire pressures
caused by an increase in the outside air
temperature or by an increase in the
temperature in the tires can cause the low
tire pressure warning light to go off. System resetting is
necessary when the
wheels are changed (for example, a
switch to snow tires) and new TPMS
valves are installed on the newly fitted
wheels. Have this work performed by a
SUBARU dealer following wheel replace-
ment.
It may not be possible to install TPMS
valves on certain wheels that are on the
market. Therefore, if you change the
wheels (for example, a switch to snow
tires), use wheels that have the same part
number as the standard-equipment
wheels. Without four operational TPMS
valve/sensors on the wheels, the TPMS
will not fully function and the warning light
in the instrument panel will illuminate
steadily after blinking for approximately
one minute.
When a tire is replaced, adjustments are
necessary to ensure continued normal
operation of the tire pressure monitoring
system. As with wheel replacement,
therefore, you s hould have the work
performed by a SUBARU dealer.

After driving approximately 600
miles (1,000 km), check the wheel
nuts again and retighten any nut
that has become loose.■ Tire ReplacementThe 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 opti-
mally matched to the characteristics of the
vehicle and were sele cted to give the best
possible combination of running perfor-
mance, ride comfort, and service life. It is
essential for every tire to have a size and
construction matching those shown on the
tire inflation pressure label and to have a
speed symbol and load index matching
those shown on the tire inflation pressure
label.
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’s ground
clearance.
All four tires must be the same in terms of
manufacturer, brand (tread pattern),
construction, and size. You are advised to
replace the tires with new ones that are identical to those fitted as standard equip-
ment.
For safe vehicle operation, SUBARU

recommends replacing all four tires at the
same time.
■ 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
 When replacing or installing
tire(s), all four tires must be the
same for the following items.
(a) Size(b) Speed symbol(c) Load index(d) Circumference(e) Construction(f) Manufacturer(g) Brand (tread pattern)(h) Degrees of wearFor items (a) to (c), you must
obey the specification that is
printed on the tire inflation pres-
sure label. The tire inflation pres-
sure label is located on the
driver’s center pillar.
If all four tires are not the same in
items (a) to (h), serious mechani-
cal damage could be caused to
the drivetrain of the car, and
affect the followings.-Ride-Handling-Braking- Speedometer/Odometer cali- bration- 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 reduce
controllability, resulting in an
accident.

Alloy Wheels
366NOTEWhen 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 loos e, tighten it to the
specified torque.
11-22. Alloy WheelsAlloy wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety.
 When any of the wheels is removed
and replaced for tire rotation or to change
a flat, 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.
 Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.
 Never let the wheel rub against sharp
protrusions or curbs.
 When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for alloy wheels.
11-23. Windshield Washer Fluid1) “LOW” positionThe washer fluid level can be checked by
observing the position of the level on the
liquid-covered holes in the gauge. 
If the level falls below the second hole
from the bottom (the “LOW” position), add
washer fluid.
Use windshield washer fluid. If windshield
washer fluid is unavailable use clean
water.
In areas where water freezes in winter,
use an anti-freeze type windshield washer
fluid.
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
during turns. The resulting loss of
vehicle control could lead to an
accident.
