Safety Precautions When Driving■ Seatbelt and SRS Airbag
For instructions and precautions, carefully
read the following sections.
 For the seatbelt syst em, refer to "Seat-
belts" P39.
 For the SRS airbag system, refer to
"SRS Airbag (Supplemental Restraint
System Airbag)" P60.

WARNING
CAUTION
Read these instructions care-
fully
Wear eye protection
Battery fluid contains sulfuric
acid
Keep children away
Keep flames away
Prevent explosions
WARNING
 All persons in the vehicle must
fasten their seatbelts BEFORE
the vehicle starts to move. Other-
wise, the possibility of serious
injury becomes greater in the
event of a sudden stop or acci-
dent. To obtain maximum protection in
the event of an accident, the
driver and all passengers must
always wear seatbelts when in
the vehicle. The SRS (Supple-
mental Restraint System) airbag
does not do away with the need to
fasten seatbelts. In combination
with the seatbelts, it offers the
best combined protection in case
of a serious accident.
Not wearing a seatbelt increases
the chance of severe injury or
death in a crash even when the
vehicle has the SRS airbag.
 The SRS airbags deploy with
considerable speed and force.
Occupants who are out of the
proper position when the SRS
airbag deploys could suffer very
serious injuries. Because the
SRS airbag needs enough space
for deployment, the driver should
always sit upright and well back
in the seat as far from the steering
wheel as practical while still
maintaining full vehicle control
and the front passenger should
move the seat as far back as
possible and sit upright and well
back in the seat.

General Information■California Perchlorate Advi -
soryCertain vehicle co mponents such as
airbag modules, seatbelt pretensioners
and keyless entry transmitter batteries
may contain perchlorate material. Special
handling may apply for service or vehicle
end of life disposal. See www.dtsc.ca.gov/
hazardouswaste /perchlorate.■Noise from under the Vehicle
NOTEYou may hear a noise from under the
vehicle approximately 5 to 10 hours
after the ignition sw itch is turned to
the “OFF” position. However, this
does not indicate a malfunction. This
noise is caused by the operation of the
fuel evaporation leakage checking
system and the operation is normal.
The noise will stop after approximately
15 minutes.
■ Vehicle Data RecordingThe vehicle is equipped with sophisticated
computers that will record certain data,
such as:
 Vehicle speed
 Engine speed
 Engine control information
 Shift state information

agency
 For use by SUBARU in a lawsuit
 For research purposes where the data
is not tied to a specific vehicle or vehicle
owner
 Do not connect any unauthorized
accessories or devices to the
data link connector (OBDII port).
This connector should be used
only with compatible diagnostic
devices for inspection and main-
tenance by an authorized service
technician using authorized
