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.

adversely affect the operation of
implanted pacemakers and
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

NOTEThe operational/non-operational
setting for the keyless access function
can be changed. For the setting proce-
dure, refer to "Disabling Keyless
Access Function" P103.
 For detailed info rmation about the
operation method fo r the push-button
ignition switch while the keyless
access function is switched to the non-
operational mode, refer to "Access Key
Fob – If Access Key Fob Does Not
Operate Properly" P325.
 The keyless access with push-
button start system uses weak radio
waves. The status of the access key
fob and environmental conditions may
interfere with the communication
between the access key fob and the
vehicle under the following conditions,
and it may not be possible to lock or
unlock the doors or start the engine.
CAUTION
 Never leave or store the access
key fob inside the vehicle or
within 6.6 ft (2 m) around the
vehicle (e.g., in the garage). The
access key fob may be locked
inside the vehicle, or the battery
may discharge rapidly. Note that
the push-button ignition switch
may not turn on in some cases
depending on the location of the
access key fob. The access key fob contains elec-
tronic components. Observe the
following precautions to prevent
malfunctions.
- It is recommended to have the
access key fob battery
replaced at an authorized
SUBARU dealer to avoid the
risk of damage.- Do not get the access key fob
wet. If the access key fob gets
wet, wipe it off immediately
and let it dry completely.- Do not apply strong impacts
to the access key fob.
- Never leave the access key
fob in direct sunlight or
anywhere that may become
hot, such as on the dash-
board. It may damage the
battery or cause circuit
malfunctions.- Do not wash the access key
fob in an ultrasonic washer.- Do not leave the access key
fob in humid or dusty loca-
tions. Doing so may cause
malfunctions.- Keep the access key fob away
from magnetic sources.- Do not leave the access key
fob near a personal computer
or home electrical appliance.- Do not leave the access key
fob near a battery charger or
any electrical accessories.- Do not apply metallic window
tint or attach metallic objects
to the windows.- Do not fit non genuine acces- sories or parts.
If the access key fob is dropped,
the integrated emergency key
inside may become loose. Be
careful not to lose the emergency
key.
 When traveling in an airplane, do
not press the button of the access
key fob. If any button of the
access key fob is pressed, radio
