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.

2-38NOTE In the following cases, contact your SUBARU dealer as soon as pos- sible.
The front part of the vehicle was involved in an accident in
which the SRS airbags did not deploy. The pad section of the steering wheel or front passenger ’s air-
bag cover is scratched, cracked, or otherwise damaged.
Precautions against vehicle modification
WARNING
To avoid accidental activation of the system or rendering the
system inoperative, which may result in serious injury, no modifi-cations should be made to any components or wiring of the SRSairbag system.This includes following modifications: Installation of custom steering wheel
Attachment of additional trim materials to the dashboard
Installation of additional electrical/electronic equipment such
as a mobile two-way radio on or near the SRS airbag system
components and/or wiring is not advisable. This could interferewith proper operation of the SRS airbag system.
CAUTION
Do not perform any of the following modifications. Such modifi-cations can interfere with proper operation of the SRS airbag sys-tem.
Attachment of any equipment (brush bar, winches, snow
plow, skid plate, etc.) other than SUBARU genuine accessoryparts to the front end Modification of the suspension system or front end structure
Installation of a tire of different size and construction from
the original tires listed on the tire placard attached to the doorjamb

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.

Aluminum wheels c an b e sc ratc hed and d amag ed easily
. Hand le them
c arefully to maintain their ap p earanc e, p erformanc e , and safety.
When any of the wheels is removed and rep lac ed for tire rotation or to
c hang e a flat, always c hec k the tig htness of the wh eel nuts after d riving
ap p roximately 600 miles (1,000 km). If any nut is l oose, tig hten it to the
sp ec ified torq ue. Never ap p ly oil to the thread ed p arts, wheel nuts, or tap ered surfac e
of the wheel. Never let the wheel rub ag ainst sharp p rotrusions o r c urb s.
Be sure to fit tire c hains on uniformly and c omp let ely around the tire,
otherwise the c hains may sc ratc h the wheel. When wheel nuts, b alanc e weig hts, or the c enter c ap are rep lac ed ,
b e sure to rep lac e them with g enuine SUBARU p arts d esig ned for alumi-
num wheels. Fuses
