SRS airbag system servicing
WARNING
When discarding an airbag module or scrapping the entire car
damaged by a collision, consult your SUBARU dealer. The SRS airbag has no user-serviceable parts. Do not use
electrical test equipment on any circuit related to the SRS airbag
system. For required servicing of the SRS airbag, see your near-
est SUBARU dealer. Tampering with or disconnecting the sys-
tem’ s wiring could result in accidental inflation of the SRS airbag
or could make the system inoperative, which may result in seri-
ous injury. The wiring harnesses of the SRS airbag system arecovered with yellow insulation and the system connectors areyellow for easy identification.
CAUTION
If you need service or repair in areas listed below, we recommend
that you have an authorized SUBARU dealer perform the work. The
SRS airbag control module, impact sensors and airbag modules
are stored in these areas.
Under the center console
Inside each front fender
Steering wheel and column and nearby areas
Top of the dashboard on front passenger ’s side and nearby
areas
In the event that the SRS airbag is deployed, replacement of the sys-
tem should be performed only by an authorized SUBARU dealer.When the components of the SRS airbag system are replaced, useonly genuine SUBARU parts.
To ensure their long -term reliab ility, the SRS airb ag s must b e insp ec ted
b y a SUBARU d ealer ten years after the d ate of manu fac ture, whic h is
shown on the c ertific ation lab el attac hed to the d r iver’s d oor.

susp ec t they may b e fuel related , try a d ifferent b rand of g asoline
b efore seeking servic e at your SUBARU d ealer. Fuel system d amag e or d riveab ility p rob lems whic h r esult from

State emission testing (U.S. only)
WARNING
Testing of an All Wheel drive vehicle must NEVER
be performed
on a single two-wheel dynamometer. Attempting to do so will result in uncontrolled vehicle movement and may cause an acci-
dent or injuries to persons nearby.
CAUTION
Resultant vehicle damage due to improper testing is not covered
under the SUBARU Limited Warranty and is the responsibility ofthe state inspection program or its contractors or licensees.
At state inspection time, remember to tell your inspection or service
station in advance not to place your SUBARU AWD vehicle on a two-
wheel dynamometer. Otherwise, serious transmission damage willresult.
Some states have started using d ynamometers in thei r state insp ec tion
p rog rams in ord er to meet their ob lig ation und er fe d eral law to imp lement
stric ter vehic le emission stand ard s to red uc e air p ollution from c ars. A
d ynamometer is a tread mill or roller-like testing d evic e that allows your
c ar ’s wheels to turn while the c ar remains in one p lac e . Dep end ing on
the severity of a state ’s air p ollution p rob lems, the states must ad op t
either a “b asic ” or “enhanc ed ” vehic le emission insp ec tion test. Nor-

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.
