webbing and all hardware periodically for cracks, cuts,
gashes, tears, damage, loose bolts or worn areas. Re-
place the seatbelts even if only minor damage is
found.
y
Keep the belts free of polishes, oils, chemi-
cals and particularly battery acid. y Never attempt to make modifications or
changes that will prevent the seatbelt from op-
erating properly.
Seatbelt extender
If the front seatbelts are not long enough to permit the
tongue plate to engage with the seatbelt buckle, an
optional seatbelt extender is available from your
SUBARU dealer. When ordering an extender, only or-
der one particularly designed for your vehicle. Several
different types of extenders are available to match var-
ious varieties of front seatbelt designs. See your
SUBARU dealer for assistance.
The extender adds approximately 8 inches (200 mm)
of length and it can be used for either the driver or front
passenger seating position.
Be sure to observe the following when using
the seatbelt extender.
Failure to follow these instructions and warn-
ings could reduce the effectiveness of the seat-
belt and result in more serious injury in the
event of a collision.y Never use the extender when the belt itself is
long enough to permit it to be buckled properly.
If removal of heavy clothing is all that is needed
to permit the seatbelt to be buckled properly,
remove the heavy clothing and do not use the

tempting to operate the wiper with the blades
frozen to the window glass could cause not
only the wiper blades to be damaged but also
the wiper motor to burn out. If the wiper blade
is frozen to the window glass, be sure to oper-ate the defroster, wiper deicer (if equipped) or
rear window defogger before turning on the
wiper.yIf the wipers stop during operation because
of ice or some other obstruction on the window,
the wiper motor could burn out even if the wiper
switch is turned off. If this occurs, promptly
stop the vehicle in a safe place, turn the ignition
switch to the “LOCK” position and clean the
window glass to allow proper wiper operation. y Use clean water if windshield washer fluid is
unavailable. In areas where water freezes in
winter, use SUBARU Windshield Washer Fluid
or the equivalent. (See “Windshield washer flu-
id” section in chapter 11.)
Also, when driving the vehicle when there are
freezing temperatures, use non-freezing type
wiper blades.y Do not clean the wiper blades with gasoline
or a solvent, such as paint thinner or benzene.
This will cause deterioration of the wiperblades.
NOTE y The wiper operates only when the ignition
switch is in the “ON” or “ACC” position. y Clean your wiper blades and window glass peri-
odically with a washer solution to prevent streak-
ing, and to remove accumulations of road salt or
road film. Keep the washer button depressed at
least for 1 second so that washer solution will be
sprinkled all over the windshield or rear window. y Grease, wax, insects or other material on the
windshield or the wiper blades results in jerky wip-
er operation and streaking on the glass. If you can-
not remove those streaks after operating the
washer or if the wiper operation is jerky, clean the
outer surface of the windshield or rear window
and the wiper blades using a sponge or soft cloth
with a neutral detergent or mild-abrasive cleaner.
After cleaning, rinse the window glass and wiper
blades with clean water. The glass is clean if no
beads form on the glass when you rinse with wa-ter. y If you cannot eliminate the streaking even after
following this procedure, replace the wiper blades
with new ones. Refer to the “Replacement of wiper

and may produce a sulfur exhaust odor or smell.
SUBARU recommends that you try a different brand of
unleaded gasoline having lower sulfur to determine if
the problem is fuel related before returning your vehi-
cle to an authorized dealer for service. The CHECK
ENGINE warning light/Malfunction indicator lamp may
also turn on. If this occurs, return to your authorized
SUBARU dealer for diagnosis. If it is determined that
the condition is caused by the type of fuel used, re-
pairs may not be covered by your warranty. TMMT
Some gasoline contains an octane-enhancing additive
called MMT (Methylcyclopentadienyl Manganese Tri-
carbonyl). If you use such fuels, your emission control
system performance may deteriorate and the CHECK
ENGINE warning light/Malfunction indicator lamp may
turn on. If this happens, return to your authorized
SUBARU Dealer for service. If it is determined that the
condition is caused by the type of fuel used, repairs
may not be covered by your warranty. T Gasoline for cleaner air
Do not let fuel spill on the exterior surfaces of
the vehicle. Fuels containing alcohol may cause paint damage, which is not covered un-
der the SUBARU Limited Warranty.
Your use of gasoline with detergent additives will help
prevent deposits from forming in your engine and fuel
system. This helps keep your engine in tune and your
emission control system working properly, and is a
way of doing your part for cleaner air. If you continu-
ously use a high quality fuel with the proper detergent
and other additives, you should never need to add any
fuel system cleaning agents to your fuel tank.
Many gasolines are now blended with materials called
oxygenates. Use of these fuels can also help keep the
air cleaner. Oxygenated blend fuels, such as MTBE
(Methyl Tertiary Butyl ether) or ethanol (ethyl or grain
alcohol) may be used in your vehicle, but should con-
tain no more than 15% MTBE or 10% ethanol for the
proper operation of your SUBARU.
In addition, some gasoline suppliers are now produc-
ing reformulated gasolines, which are designed to re-
duce vehicle emissions. SUBARU approves the use of reformulated gasoline.
If you are not sure what the fuel contains, you should
ask your service station operators if their gasolines
contain detergents and oxygenates and if they have

2Maintenance and service
1) Rubber gaskets
6. Put the radiator cap back on and tighten firmly. At
this time, make sure that the rubber gasket in the radi-
ator cap is correctly in place.
7. Start and run the engine for more than five minutes
at 2,000 to 3,000 rpm.
8. Stop the engine and wait until the coolant cools
down (122 to 140 °F [50 to 60 °C]). If there is any loss
of coolant, add coolant to the radiator’s filler neck and
to the reserve tank’s “FULL” level.
9. Put the radiator cap and reservoir cap back on and
tighten firmly.
Air cleaner element
Do not operate the engine with the air cleaner
element removed. The air cleaner element not
only filters intake air but also stops flames if the
engine backfires. If the air cleaner element is
not installed when the engine backfires, you
could be burned.
The air cleaner element functions as a filter screen.
When the element is perforated or removed, engine
wear will be excessive and engine life shortened.
The air cleaner element is a viscous type. It is unnec-
essary to clean or wash the element. „ Replacing the air cleaner element
Replace the air cleaner element according to the
maintenance schedule in the “Warranty and Mainte-
nance Booklet”. Under extremely dusty conditions, re-
place it more frequently. It is recommended that you
always use genuine SUBARU parts.

freeze type windshield washer fluid. SUBARU Wind-
shield Washer Fluid contains 58.5% methyl alcohol
and 41.5% surfactant, by volume. Its freezing temper-
ature varies according to how much it is diluted, as in-
dicated below.Replacement of wiper blades
Grease, wax, insects, or other materials on the wind-
shield or the wiper blade results in jerky wiper opera-
tion and streaking on the glass. If you cannot remove
the streaks after operating the windshield washer or if
the wiper operation is jerky, clean the outer surface of
the windshield (or rear window) and the wiper blades
using a sponge or soft cloth with a neutral detergent or
mild-abrasive cleaner. After cleaning, rinse the wind-
shield and wiper blades with clean water. The wind-
shield is clean if beads do not form when you rinse the
windshield with water.
Do not clean the wiper blades with gasoline or
a solvent, such as paint thinner or benzene.
This will cause deterioration of the wiper
blades.
If you cannot eliminate the streaking even after follow-
ing this method, replace the wiper blades using the fol-
lowing procedures:
Washer Fluid Concentration Freezing Temperature

50% –4 °F (–20 °C)
