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
 Driving information, etc.
▼ Data usageSUBARU may use the data recorded in
this computer to diagnose malfunctions,
conduct research and development, and
improve quality.
SUBARU will not disclose the recorded
data to a third party except:
 With the consent of the vehicle owner
or with the consent of the lessee if the
vehicle is leased
 In response to an official request by the
police, a court of law or a government
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
service tools. Connecting unau-
thorized devices, such as a
driver-behavior tracking device,
may adversely affect vehicle
systems, including safety
systems, or allow others to
access information stored in your
vehicle. The use of unauthorized
devices may also cause unex-
pected malfunctions, such as a
drained battery, or may damage
vehicle systems. The manufac-
turer’s warranty will not cover
any part that malfunctions, fails,
or is damaged due to the use of
an unauthorized device with the
data link connector.

implanted defibrillators.If you wear electronic medical
equipment other than an implanted
pacemaker or an implanted
defibrillator, before using the key-
less access with push-button start
system, refer to “Radio waves used
for the keyless access with push-
button start system” mentioned
