„ System servicing
If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt pre-
tensioners and/or SRS airbag sys-
tem. Immediately take your vehicle
to your nearest SUBARU dealer to
have the system checked. Unless
checked and properly repaired, the
seatbelt pretensioners and/or SRS
airbags will operate improperly (e.g.
SRS airbags may inflate in a very mi-
nor collision or not inflate in a se-
vere collision), which may increase
the risk of injury.
yFlashing or flickering of the warn-
ing light
yNo illumination of the warning
light when the ig nition switch is
first turned to the “ON” position
y Continuous illumination of the
warning light
yIllumination of the warning light
while driving
yWhen discarding a seatbelt retrac-
tor assembly or scrapping the en-
tire vehicle damaged by a colli-
sion, consult yo ur SUBARU deal-
er.

NOTE
If the front part of the vehicle is dam-
aged in an accident to the extent that
the seatbelt pretensioner does not op-
erate, contact your SUBARU dealer as
soon as possible. „ Precautions against vehicle
modification
Always consult your SUBARU dealer if
you want to install any accessory parts to
your vehicle.y Tampering with or disconnecting
the system’s wiring could result in
accidental activation of the seat-
belt pretensioner and/or airbag or
could make the system inopera-
tive, which may result in serious
injury. The wiring harnesses of
the seatbelt pretensioner and SRS
airbag systems are covered with
yellow insulation and the connec-
tors of the system are yellow for
easy identification. Do not use
electrical test equipment on any
circuit related to the seatbelt pre-
tensioner and airbag systems. For
required servicing of the seatbelt
pretensioner, see your nearest
SUBARU dealer.
The front sub sensors are located in
both front fenders and the airbag
control module including the impact
sensors is located under the center
console. If you need service or re-
pair in those areas or near the front
seatbelt retractors, have an autho-
rized SUBARU dealer perform the
work.
Do not perform any of the following
modifications. Such modifications
can interfere with proper operation
of the seatbelt pertensioners. y Attachment of any equipment
(bush bar, winches, snow plow,
skid plate, etc.) other than genu-
ine SUBARU accessory parts to
the front end.
y Modification of the suspension
system or front end structure.
yInstallation of a tire of different
size and construction from the
tires specified on the vehicle plac-
ard attached to the door pillar or
specified for individual vehicle
models in this Owner’s Manual.

yThe SRS airbag has no user-ser-
viceable parts. Do not use electri-
cal test equipment on any circuit
related to the SRS airbag system.
For required servicing of the SRS
airbag, see your nearest SUBARU
dealer. Tampering with or discon-
necting the system’s wiring could
result in accidental inflation of the
SRS airbag or could make the sys-
tem inoperative, which may result
in serious injury. The wiring har-
nesses of the SRS airbag system
are covered with yellow insulation
and system connectors are yellow
for easy identification.

In the event that the SRS airbag is de-
ployed, replacement of the system
should be performed only by an autho-
rized SUBARU dealer. When the com-
ponents of the SRS airbag system are
replaced, use only genuine SUBARU parts.
NOTE
In the following cases, contact your
SUBARU dealer as soon as possible. y
The front part of the vehicle was in-
volved in an accident in which the only
the driver’s SRS frontal airbag or both
driver’s and front passenger’s SRS
frontal airbags did not deploy.y The pad of the steering wheel, the
cover over the front passenger’s SRS
frontal airbag, or either roof side (from
the front pillar to a point over the rear
seat) is scratched, cracked, or other-
wise damaged.y Either center pillar and rear wheel
house or a nearby area of the vehicle
was involved in an accident in which
the SRS side airbag and SRS curtain
airbag did not deploy. y The fabric or leather of either front
seatback is cut, frayed, or otherwise
damaged. „
Precautions against vehicle
modificationIf you need service or repair in areas
listed in the following, have an au-
thorized SUBARU dealer perform
the work. The SRS airbag control
module, impact sensors and airbag
modules are stored in these areas. yUnder the center console
y Inside each front fender
y Steering wheel and column and
nearby areas
y Top of the dashboard on front
passenger’s side and nearby ar-
eas
y Each front seat and nearby area
y Inside each center pillar
y In each roof side (from the front
pillar to a point over the rear seat)
y Between the rear seat cushion
and rear wheel house on eachside
yTo avoid accidental activation of
the system or rendering the sys-
tem inoperative, which may result
in serious injury, no modifications
should be made to any compo-
nents or wiring of the SRS airbag
system.
This includes following modifica- tions:
yInstallation of custom steering
wheels
yAttachment of additional trim
materials to the dashboard
yInstallation of custom seats
yReplacement of seat fabric or
leather
yInstallation of additional fabric
or leather on the front seat

1-62 Seat, seatbelt and SRS airbags
Always consult your SUBARU dealer if
you want to install any accessory parts on
your vehicle.
yAttachment of a hands-free mi-
crophone or any other accesso- ry to a front pillar , a center pillar,
a rear pillar, the windshield, a
side window, an assist grip, or
any other cabin surface that
would be near a deploying SRS
curtain airbag.
y Installation of additional electri-
cal/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 inter-
fere with proper operation of the
SRS airbag system.
Do not perform any of the following
modifications. Such modifications
can interfere with proper operation
of the SRS airbag system. y Attachment of any equipment
(bush bar, winches, snow plow,
skid plate, etc.) other than genu-
ine SUBARU accessory parts.
y Modification of the suspension
system or front end structure.
yInstallation of a tire of different
size and construction from the
tires specified on the vehicle plac-
ard attached to the driver’s door
pillar or specified for individual
vehicle models in this Owner’s
Manual.
y Attachment of any equipment
(side steps or side sill protectors,
etc.) other than genuine SUBARU
accessory parts to the side body.

11 - 4 Maintenance and service
„Before checking or servicing
in the engine compartment
„When you do checking or ser-
vicing in the engine compart-
ment while the engine is run-ning
Engine hood
To open the hood:
1. If the wiper blades are lifted off the
windshield, return them to their original
positions.
2. Pull the hood release knob under the
instrument panel.yWear adequate eye protection to
guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly wash
them out with clean water.
yDo not tamper wi th the wiring of
the SRS airbag system or seatbelt
pretensioner system, or attempt
to take its connectors apart, as
that may activate the system or it
can render it inoperative. The wir-
ing and connectors of these sys-
tems are yellow for easy identifi-
cation. NEVER use a circuit tester
for these wiring.
If your SRS airbag or seatbelt pre-
tensioner needs service, consult
your nearest SUBARU dealer.
y Always stop the engine and set
the parking brake firmly to pre-
vent the vehicle from moving.
yAlways let the engine cool down.
Engine parts b ecome very hot
when the engine is running and
remain hot for some time after the
engine is stopped.
y Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
yAlways remove the key from the
ignition switch. When the ignition
switch is in the “ON” position, the
cooling fan may operate suddenly
even when the engine is stopped.
A running engine can be dangerous.
Keep your fingers, hands, clothing,
hair and tools away from the cooling
fan, belts and any other moving en-
gine parts. Removing rings, watch-
es and ties is advisable.
