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.

Tires and wheels WARNING
When replacing a tire, make sure you use only the same size,
circumference, construction brand, and load range as the original tires listed on the tire placard. Using other sizes, circumferencesor construction may result in severe mechanical damage to the
drive train of your vehicle and may affect ride, handling, braking,
speedometer/odometer calibration, and clearance between thebody and tires. It also may be dangerous and lead to loss of ve-hicle control. Do not use a combination of radial, belted bias or bias tires
since it may cause dangerous handling characteristics and leadto an accident. Do not let air out of warm tires to adjust pressure. Doing so
will result in low tire pressure.
