Maintenance and service
the materials in the vehicle may be hazardous if
improperly used or handled, for example, bat-tery acid. y
Your vehicle should only be serviced by per-
sons fully competent to do so. Serious person-
al injury may result to persons not experienced
in servicing vehicles. y Always use the proper tools and make certain
that they are well maintained. y Never get under the vehicle supported only
by a jack. Always use a safety stands to sup-
port the vehicle. y Never keep the engine running in a poorly
ventilated area, such as a garage or other
closed areas. y Do not smoke or allow open flames around
the fuel or battery. This will cause a fire. y Because the fuel system is under pressure,
replacement of the fuel filter should be per-
formed only by your SUBARU dealer.y Wear adequate eye protection to guard
against getting oil or fluids in your eyes. If
something does get in your eyes, thoroughly
wash them out with clean water. y Do not tamper with the wiring of the SRS air-
bag system or seatbelt pretensioner system, or
attempt to take its connectors apart, as that may activate the system or it can render it inop-
erative. The wiring and connectors of these
systems are yellow for easy identification. NEV-
ER use a circuit tester for these wiring.
If your SRS airbag or seatbelt pretensioner
needs service, consult your nearest SUBARU
dealer.
„ Before checking or servicing in the en-
gine compartment
yAlways stop the engine and set the parking
brake firmly to prevent the vehicle from mov-
ing. y Always let the engine cool down. Engine
parts become very hot when the engine is run-
ning and remain hot for some time after the en-
gine is stopped.y Do not spill engine oil, engine coolant, brake
fluid or any other fluid on hot engine compo-
nents. This may cause a fire.y Always remove the key from the ignition
switch. When the ignition switch is in the “ON”
position, the cooling fan may operate suddenly

Battery
yBefore beginning work on or near any bat-
tery, be sure to extinguish all cigarettes, match-
es, and lighters. Never expose a battery to an
open flame or electric sparks. Batteries give off
a gas which is highly flammable and explosive.y For safety, in case an explosion does occur,
wear eye protection or shield your eyes when
working near any battery. Never lean over a bat-tery. y Do not let battery fluid contact eyes, skin,
fabrics, or paint because battery fluid is a cor-
rosive acid. If battery fluid gets on your skin or
in your eyes, immediately flush the area with
water thoroughly. Seek medical help immedi-
ately if acid has entered the eyes.
If battery fluid is accidentally swallowed, imme-
diately drink a large amount of milk or water,
and seek medical attention immediately. y To lessen the risk of sparks, remove rings,
metal watchbands, and other metal jewelry.
Never allow metal tools to contact the positive
battery terminal and anything connected to it
WHILE you are at the same time in contact with any other metallic portion of the vehicle be-
cause a short circuit will result.y
Keep everyone including children away from
the battery.y Charge the battery in a well-ventilated area.
y Battery posts, terminals and related accesso-
ries contain lead and lead compounds, chemi-
cals known to the State of California to cause
cancer and reproductive harm. Batteries also
contain other chemicals known to the State of
California to cause cancer. Wash hands after
handling.

Maintenance and service
1) Cap
2) Upper level
3) Lower level
It is unnecessary to periodically check the battery fluid
level or periodically refill with distilled water.
However, if the battery fluid level is below the lower
level, remove the cap. Fill to the upper level with dis-
tilled water.
Never use more than 10 amperes when charg-
ing the battery because it will shorten battery
life.
