performing maintenance on your
vehicle. Always be very careful to avoid
injury when working on the
vehicle. Remember that some of
the materials in the vehicle may
be hazardous if improperly used
or handled, for example, battery
acid.
 Your vehicle should only be
serviced by persons fully compe-
tent to do so. Serious personal
injury may result to persons not
experienced in servicing vehi-
cles. Always use the proper tools and
make certain that they are well
maintained. Never get under the vehicle
supported only by a jack. Always
use safety stands to support the
vehicle. Never keep the engine running in
a poorly ventilated area, such as a
garage or other closed areas. Do not smoke or allow open
flames around the fuel or battery.
This will cause a fire. Because the fuel system is under
pressure, replacement of the fuel
filter should be performed only by
your SUBARU dealer. 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.

WARNING
 Before beginning work on or near
any battery, be sure to extinguish
all cigarettes, matches, and
lighters. Never expose a battery
to an open flame or electric
sparks. Batteries give off a gas
which is highly flammable and
explosive. For safety, in case an explosion
does occur, wear eye protection
or shield your eyes when working
near any battery. Never lean over
a battery. Do not let battery fluid contact
eyes, skin, fabrics, or paint
because battery fluid is a corro-
sive acid. If battery fluid gets on
your skin or in your eyes, immedi-
ately flush the area with water
thoroughly. Seek medical help
immediately if acid has entered
the eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water,
and seek medical attention
immediately.

other chemicals known to the
State of California to cause
cancer. Wash hands after
handling.
CAUTION

when charging the battery because
it will shorten battery life.
