Flat tires
WARNING
Do not jack up the vehicle on an incline or a loose road sur-
face. The jack can come out of the jacking point or sink into theground and this can result in a severe accident. Use only the jack provided with your vehicle. The jack sup-
plied with the vehicle is designed only for changing a tire. Neverget under the vehicle while supporting the vehicle with this jack. Always turn the engine off before raising the flat tire off the
ground using the jack. Never swing or push the vehicle sup-ported with the jack. The jack can come out of the jacking pointdue to a jolt and this can result in a severe accident. Do not use oil or grease on the wheel studs or nuts when the
spare tire is installed. This could cause the nuts to become looseand lead to an accident. Never place a tire or tire changing tools in the passenger
compartment after changing wheels. In a sudden stop or colli-
sions, loose equipment could strike occupants and cause injury.Store the tire and all tools in the proper place.
If you have a flat tire while d riving , never b rake sud d enly; keep d riving
straig ht ahead while g rad ually red uc ing sp eed . Then slowly p ull off the
road to a safe p lac e.
1. Park on a hard , level surfac e, whenever p ossib le, then stop the en-
g ine.
2. Set the p arking b rake sec urely and shift a manual transmission ve-
hic le in reverse or an automatic transmission vehic le in the “P ” (Park)
p osition.

vehicle is being towed because the steering wheel and the direc- tion of the wheels will be locked. Remember that the brake booster and power steering do not
function when the engine is not running. Because the engine isturned off, it will take greater effort to operate the brake pedal andsteering wheel.

When washing the vehicle, the brakes may get wet. As a result,
the brake stopping distance will be longer. To dry the brakes, drive the vehicle at a safe speed while lightly pressing the brakepedal to heat up the brakes. Do not wash the engine compartment and areas adjacent to it.
If water enters electrical parts or the power steering fluid reser-
voir, it will cause engine trouble or faulty power steering respec-
tively.
The b est way to p reserve your vehic le ’s b eauty is freq uent washing .

WARNING
Testing of a Full-Time All-Wheel Drive vehicle must NEVER be
performed on a single two-wheel dynamometer or similar appara-
tus nor should you install FWD fuse in the engine compartment.Attempting to do so will result in transmission damage and inuncontrolled vehicle movement and may cause an accident or
injuries to persons nearby. Always select a safe area when performing maintenance on
your vehicle. Always be very careful to avoid injury when working on the ve-
hicle. Remember that some of the materials in the vehicle may behazardous if improperly used or handled, for example, batteryacid. 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 vehicles.

10-4
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.
