1) Filler hole
2) Drain hole
3) Oil level
Remove the plug from the filler hole and check the oil
level. The oil level should be kept even with the bottom
of the filler hole. If the oil level is below the bottom
edge of the hole, add oil through the filler hole to raise the level.
If the vehicle requires frequent refilling, there
may be an oil leak. If you suspect a problem,
have the vehicle checked at your SUBARU deal-
er.

1) Specified range
2. Check the fluid level of the reservoir tank.
When the fluid is hot after the vehicle has been run:
Check that the oil level is between “HOT MIN” and
“HOT MAX” on the surface of the reservoir tank.
When the fluid is cool before the vehicle is run: Check
that the oil level is between “COLD MIN” and “COLD
MAX” on the surface of the reservoir tank.
3. If the fluid level is lower than the applicable “MIN”
line, add the recommended fluid as necessary to bring
the level between the “MIN” and “MAX” line.
If the fluid level is extreme low, it may indicate possible
leakage. Consult your SUBARU dealer for an inspec- tion.
Be careful not to burn yourself because the flu-id may be hot.
y
When power steering fluid is being added,
use only clean fluid, and be careful not to allow
any dirt into the tank. And never use different
brands together.
y Avoid spilling fluid when adding it in the tank.

Maintenance and service
Use only those wheels that are specified for
your vehicle. Wheels not meeting specifica-
tions 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 acci-
dent.
NOTE
When any of the wheels is removed and replaced
for tire rotation or to change a flat tire, alwayscheck 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.
Aluminum wheels
Aluminum wheels can be scratched and damaged
easily. Handle them carefully to maintain their appear-
ance, performance, and safety. y
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.y Never apply oil to the threaded parts, wheel nuts, or
tapered surface of the wheel.y Never let the wheel rub against sharp protrusions or
curbs. y Be sure to fit tire chains on uniformly and completely
around the tire, otherwise the chains may scratch the
wheel.y When wheel nuts, balance weights, or the center
cap is replaced, be sure to replace them with genuine
SUBARU parts designed for aluminum wheels.

Headlights (U.S.-spec. WRX-STi)
High-intensity-discharge (HID) bulbs are used
for the low beams of the headlights on the U.S.-
spec. WRX-STi. These HID bulbs use an ex-
tremely high voltage. To avoid the risk of an
electric shock and resulting serious injury, you
should not attempt to replace them. Neither
should you attempt to replace the high-beam
bulbs, remove/refit the headlight assemblies,
or remove any headlight-assembly compo-
nents. For replacement of the headlight bulbs
(low-beam and high-beam), removal and instal-
lation of the headlight assemblies, and removal
of headlight-assembly components, contact
your SUBARU dealer.

Consumer information and Reporting safety defects
– CONTINUED –
hicle control could lead to an accident. TMeasuring and adjusting air pressure to
achieve proper inflation
Check 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 pres-
sures. Also, the tire pressures are affected by the
outside temperature. It is best to check tire pres-
sure outdoors 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
y 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. y Maximum inflation pressure The maximum cold inflation pressure to which a
tire may be inflated. y
Recommended inflation pressure
The cold inflation pressure recommended by a
vehicle manufacturer. y 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
sidewall of the tire, or
2)The outward facing sidewall of an asymmet-
rical tire that has a particular side that must al-
ways face outward when mounting on a vehi- cle.
y Accessory weight
The combined weight (in excess of those stan-
dard items which may be replaced) of floor mats,
leather seats and cross bars to the extent that
these items are available as factory-installed
equipment (whether installed or not). y Curb weight
The weight of a motor vehicle with standard
equipment including the maximum capacity of fu-
el, oil, and coolant and air conditioning.
