Front seatbelt pretensioners
WARNING
To obtain maximum protection, occupants should sit in an up-
right position with their seatbelts properly fastened. Refer to
“Seatbelts” section in this chapter.
Do not modify, remove or strike the front seatbelt retractor as-
semblies or surrounding area. This could result in accidental ac-tivation of the seatbelt pretensioners or could make the system
inoperative, possibly resulting in serious injury. Seatbelt preten-sioners have no user-serviceable parts. For required servicing of
front seatbelt retractors equipped with seatbelt pretensioners,
see your nearest SUBARU dealer. When discarding front seatbelt retractor assemblies or scrap-
ping the entire car due to collision damage or for other reasons,
consult your SUBARU dealer.

Seatbelt retractor assembly (Pretensioner)
The d river
’s and front p asseng er ’s seatb elts have a seatb elt p reten-
sioner. The seatb elt p retensioners are d esig ned to b e ac tivated in the
event of an ac c id ent involving a mod erate to severe frontal c ollision.
The p retensioner sensor also serves as a SRS fronta l airb ag sensor. If
the sensor d etec ts a c ertain p red etermined amount o f forc e d uring a
frontal c ollision, the front seatb elt is q uic kly d r awn b ac k in b y the re-
trac tor to take up the slac k so that the b elt more effec tively restrains

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.

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.

If the front sub sensors insid e the b oth front fend ers and the imp ac t
sensors in the airb ag c ontrol mod ule d etec t a c erta in p red etermined
amount of forc e d uring a frontal c ollision, the c on trol mod ule send s
sig nals to the frontal airb ag mod ules instruc ting t hem to inflate the
SRS frontal airb ag s. Then b oth airb ag mod ules p rod u c e g as, whic h
instantly inflates d river ’s and p asseng er ’s SRS frontal airb ag s. After
the d ep loyment, the SRS airb ag s immed iately start t o d eflate so that
the d river ’s vision is not ob struc ted . The time req uired from d etec ting
imp ac t to the d eflating SRS airb ag after d ep loyment is shorter than
the b link of eye.
The front p asseng er ’s SRS frontal airb ag d ep loys tog ether with d riv-
er ’s SRS frontal airb ag even when no one oc c up ies the front p assen-
g er ’s seat.
When the SRS frontal airb ag s d ep loy, the d river ’s and front p assen-
g er ’s seatb elt p retensioners op erate at the same time.
Althoug h it is hig hly unlikely that the SRS airb ag would ac tivate in a
non-ac c id ent situation, should it oc c ur, the SRS ai rb ag will d eflate
q uic kly, not ob sc uring vision and will not interfer e with the d river’s
ab ility to maintain c ontrol of the vehic le.
