Always use the proper tools and make certain that they are
well maintained. Never get under the vehicle supported only by jack. Always
use a 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. Wear adequate eye protection to guard against getting oil or
other fluids in your eyes. If something does get in your eyes,
thoroughly wash it out with clean water. Because the fuel system is under pressure, replacement of the
fuel filter should be performed only by your SUBARU dealer. The SRS airbag has no user-serviceable parts. Tampering with
or disconnecting the system ’s wiring could result in accidental
inflation of the airbag or could make the system inoperative,
which may result in serious injury. The wiring harnesses of theSRS airbag system are covered with yellow insulation and the
connectors of the system are yellow, for easy identification. Donot use electrical test equipment on any circuit related to the SRSairbag system. For required servicing of the SRS airbag, see your
nearest SUBARU dealer. Before checking or servicing in the engine compart- ment
Always stop the engine and set the parking brake firmly to pre-
vent the vehicle from moving. Always let the engine cool down. Engine parts become very
hot when the engine is running and remain hot for some time af-ter the engine is stopped. Do not spill engine oil, engine coolant, brake fluid or any other
fluid on hot engine components. This may cause a fire. Always remove the key from the ignition switch. When the
ignition switch is in the “ON” position, the cooling fan may oper-
ate suddenly even when the engine is stopped.

Checking the fluid level
WARNING
Never let brake fluid contact your eyes because brake fluid can
be harmful to your eyes. If brake fluid gets in your eyes, immedi-
ately flush them thoroughly with clean water. For safety, whenperforming this work, wearing eye protection is advisable. Brake fluid absorbs moisture from the air. Any absorbed mois-
ture can cause a dangerous loss of braking performance. If the vehicle requires frequent refilling, there may be a leak. If
you suspect a problem, have the vehicle checked at your
SUBARU dealer.

WARNING
Before beginning work on or near any battery, be sure to extin-
guish all cigarettes, matches, and lighters. Never expose a bat- tery to an open flame or electric sparks. Batteries give off a gaswhich is highly flammable and explosive. For safety, in case an explosion does occur, wear eye protec-
tion 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 be-
cause battery fluid is a corrosive acid. If battery fluid gets on yourskin or in your eyes, immediately flush the area with water thor-
oughly. Seek medical help immediately if acid has entered the
