System monitors
HB4010EC
A d iag nostic system c ontinually monitors the read in ess of the seatb elt
p retensioner while the vehic le is b eing d riven. The seatb elt p reten-
sioners share the c ontrol mod ule with the airb ag sy stem. Therefore, if
any malfunc tion oc c urs in a seatb elt p retensioner, the SRS airb ag sys-
tem warning lig ht will illuminate. The SRS airb ag s ystem warning lig ht
will show normal system op eration b y lig hting for a b out 6 sec ond s
when the ig nition key is turned to the “ON ” p osition.
The following c omp onents are monitored b y the ind ic ator:
Front sub sensor (Rig ht hand sid e)
Front sub sensor (Left hand sid e)
Airb ag c ontrol mod ule (inc lud ing imp ac t sensors)
Seatb elt p retensioner (Driver ’s sid e)
Seatb elt p retensioner (Passeng er ’s sid e)
All related wiring
In the event of a malfunc tion ind ic ated b y any of f ollowing , the vehic le
should b e taken p romp tly to your nearest SUBARU d ea ler to have the
system c hec ked . Unless c hec ked and rep aired , the se atb elt p reten-
sioners and airb ag s will not func tion reliab ly: Flashing or flic kering of the ind ic ator lig ht.
No illumination of the warning lig ht when the ig nit ion switc h is
first turned to the “ON ” p osition.
Continuous illumination of the warning lig ht.
Illumination of the warning lig ht while d riving .

System servicing
WARNING
When discarding a seatbelt retractor assembly or scrapping
the entire car damaged by a collision, consult your SUBARU deal-
er. Tampering with or disconnecting the system ’s wiring could re-
sult in accidental activation of the seatbelt pretensioner and/orairbag or could make the system inoperative, which may result in
serious injury. The wiring harnesses of the seatbelt pretensionerand SRS airbag systems are covered with yellow insulation andthe connectors of the system are yellow for easy identification.Do not use electrical test equipment on any circuit related to theseatbelt pretensioner and airbag systems. For required servicing
of the seatbelt pretensioner, see your nearest SUBARU dealer.
CAUTION
The front sub sensors are located in both front fenders and theairbag control module including the impact sensors is locatedunder the center console. If you need service or repair in those
areas or near the front seatbelt retractors, we recommend thatyou have an authorized SUBARU dealer perform the work.
NOTE If the front part of the vehicle is damaged in an accident to the extent that the seatbelt pretensioner does not operate, contactyour SUBARU dealer as soon as possible. Precautions against vehicle modification CAUTION
Do not perform any of the following modifications. Such modifi- cations can interfere with proper operation of the seatbelt perten-sioners.

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 system connectors are yellowfor 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 Each front seat and nearby area (only for vehicle with SRS
side airbags) Inside each center pillar

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.
NOTE 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 frontal airbags did not deploy. The pad section of the steering wheel or front passenger ’s
frontal airbag cover is scratched, cracked, or otherwise damaged.
In addition, if your vehicle is equipped with SRS side airbags, con-tact your SUBARU dealer as soon as possible in the followingcases. Either center pillar or a nearby area of the vehicle was involved
in an accident in which the SRS side airbag did not deploy. The fabric or leather of either front seatback is cut, frayed, 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 wheels
Attachment of additional trim materials to the dashboard
Installation of custom seats (only for vehicles with SRS side

1-70airbags)
Replacement of seat fabric or leather (only for vehicles with
SRS side airbags) Installation of additional fabric or leather on the front seat
(only for vehicles with SRS side airbags)
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 accessory parts tothe 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 door jamb. Attachment of any equipment (side steps or side sill protec-
tors, etc.) other than SUBARU genuine accessory parts to theside body (only for vehicles with side airbags).
Always c onsult your SUBARU d ealer if you want to in stall any ac c essory
p arts to your vehic le.

WARNING
Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not designed to sustain the towing load.
Use of the temporary spare tire when towing can result in failureof the spare tire and/or less stability of the vehicle.
Make sure that all the tires on your vehic le are p r op erly inflated .

d oor striker on the d river ’s sid e. Ad just the rear tire p ressure to the
rec ommend ed p ressure shown on the tire p lac ard when the tires
are c old . Normal p ressure should b e maintained in t he front tires.
Other models: It is rec ommend ed to inflate the rear tires to 3 p si
(20 kPa, 0.2 kg /c m 2
) ab ove their normal op erating p ressure when
the tires are c old . Normal p ressure should b e maint ained in the
front tires.
Trailer tire c ond ition, size, load rating and p rop e r inflation p ressure
should b e in ac c ord anc e with the trailer manufac tur er’s sp ec ific ations.
In the event your vehic le g ets a flat tire when tow ing a trailer, ask a
c ommerc ial road servic e to rep air the flat tire.
If you c arry a reg ular size sp are tire in your vehi c le or trailer as a p re-
c aution ag ainst g etting a flat tire, b e sure that t he sp are tire is firmly
