Seat heater (if equipped)
HG1004BA
The seat heater operates when the ignition switch is
either in the “ACC” or “ON” position.
To turn on the seat heater, push the “LO” or “HI”
position on the switch, as desired, depending on the
temperature.
HG1007BB
1) HI – Rapid heating
2) LO – Normal heating
The indicator located on the switch comes on when the seat heater is in operation. When the vehicle ’s in-
terior is warmed enough or before you leave the ve-
hicle, be sure to turn the switch off.
CAUTION
There is a possibility that people with deli-
cate skin may suffer slight burns even at low
temperatures if he/she uses the seat heaterfor a long period of time. When using the
heater, always be sure to warn the personsconcerned.

When securing a child restraint system on the rear seats by the use of the seatbelt, the seatbelt mustbe changed over to the Automatic Locking Retractor(ALR) mode.
When the child restraint system is removed, make
sure that the seatbelt retracts fully and the retractor
returned to the Emergency Locking Retractor (ELR) mode.
For instructions on how to convert the retractor to
the ALR mode and restore it to the ELR mode, seethe “Child restraint systems ” section in this chapter.
Seatbelt warning light and chime
Your vehicle is equipped with a seatbelt warningdevice at the driver ’s seat, as required by current
safety standards.
This device causes the seatbelt warning light on the
instrument panel to light up for about six seconds
when the ignition switch is turned to “ON” to remind
the driver to wear the seatbelt. If the driver ’s seatbelt
is not fastened, a warning chime sounds at thesame time.
Fastening the seatbelt
WARNING
Never use a belt that is twisted or reversed.
In an accident, this can increase the risk or
severity of injury. Keep the lap belt as low as possible on your
hips. In a collision, this spreads the force of the lap belt over stronger hip bones instead ofacross the weaker abdomen. Seatbelts provide maximum restraint when
the occupant sits well back and upright in the
seat. To reduce the risk of sliding under the
seatbelt in a collision, the front seatbacksshould be always used in the upright position
while the vehicle is running. If the front seat-
backs are not used in the upright position in a
collision, the risk of sliding under the lap belt
and of the lap belt sliding up over the abdo- men will increase, and both can result in seri-ous internal injury or death. Do not put cushions or any other materials
between occupants and seatbacks or seat
cushions. If you do so, the risk of sliding under the lap belt and of the lap belt sliding up over the abdomen will increase, and both

SUBARU dealer as soon as possible. When you sell your vehicle, we urge you to
explain to the buyer that it has seatbelt preten-sioners by alerting him to the contents of thissection.
WARNING
To obtain maximum protection, the occu-
pants should sit in an upright position with their seatbelts properly fastened. Refer to the
“Seatbelts” section in this chapter.
Do not modify, remove or strike the front
seatbelt retractor assemblies or surrounding
area. This could result in accidental activationof the seatbelt pretensioners or could makethe system inoperative, possibly resulting in
serious injury. Seatbelt pretensioners have no
user-serviceable parts. For required servicingof front seatbelt retractors equipped with seat-
belt pretensioners, see your nearest SUBARU
dealer. When discarding front seatbelt retractor
assemblies or scrapping the entire car due to
collision damage or for other reasons, consult
your SUBARU dealer.
System monitors
HG1016BA
A diagnostic system continually monitors the readi-
ness of the seatbelt pretensioner while the vehicle is
being driven. The seatbelt pretensioners share the
control module with the SRS airbag system. There-
fore, if any malfunction occurs in a seatbelt preten-
sioner, the SRS airbag system warning light will illu-
minate. The SRS airbag system warning light will
show normal system operation by lighting for about
6 seconds when the ignition key is turned to the
“ON” position.
The following components are monitored by the indi- cator: Front sub sensor (Right hand side)

Operation
The SRS airbag can function only when the ignition switch is in the “ON” position.
If the front sub sensors inside the both front fenders
and the impact sensors in the airbag control module
detect a certain predetermined amount of force dur-
ing a frontal collision, the control module sends sig-
nals to the frontal airbag modules instructing them to
inflate the SRS frontal airbags. Then both airbag
modules produce gas, which instantly inflates driv-er’ s and passenger ’s SRS frontal airbags. After the
deployment, the SRS airbags immediately start to
deflate so that the driver ’s vision is not obstructed.
The time required from detecting impact to the de-
flating SRS airbag after deployment is shorter thanthe blink of an eye. The front passenger
’s SRS frontal airbag deploys to-
gether with driver ’s SRS frontal airbag even when no
one occupies the front passenger ’s seat.
Although it is highly unlikely that the SRS airbagwould activate in a non-accident situation, should it
occur, the SRS airbag will deflate quickly, not ob-
scuring vision and will not interfere with the driver ’s
ability to maintain control of the vehicle.

deploys between the occupant and the door panel
and supplements the seatbelt by reducing the im-pact on the occupant’s chest.
Operation
The SRS side airbag can function only when the
ignition switch is in the “ON” position.
The driver ’s and front passenger ’s SRS side airbags
deploy independently of each other since each has
its own impact sensor. Also, the SRS side airbag de-
ploys independently of the frontal airbags in the steering wheel and instrument panel.
An impact sensor is incorporated into each of the
vehicle’ s center pillars. If either sensor detects a
certain predetermined amount of force during a side
impact collision, the control module sends a signal to the side airbag module on the impacted side of the vehicle, instructing it to inflate the SRS side air-
bag. Then the side airbag module produces gas,which instantly inflates the SRS side airbag. After
the deployment, the SRS side airbag immediately
starts to deflate. The time required from detecting
impact to deflating of the SRS side airbag after de-
ployment is shorter than the blink of an eye.

All related wiring
In the event of a malfunction indicated by any of fol-
lowing, the vehicle should be taken promptly to your
nearest SUBARU dealer to have the system
checked. Unless checked and repaired, the SRS
airbags will not function reliably: Flashing or flickering of the indicator light.

tion switch is first turned to the “ON” position.
