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

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

44Inspect the seatbelts and attachments
including the webbing and all hardware
periodically for cracks, cuts, gashes,
tears, damage, loose bolts or worn areas.
Replace the seatbelts even if only minor
damage is found.
1-5. Seatbelt PretensionersThe following seatbelts have a seatbelt
pretensioner.
 Driver’s seatbelt
 Front passenger’s seatbelt
The seatbelt preten sioners are designed
to be activated in the event of an accident
involving a moderate to severe frontal and
side collision and rollover accident.
NOTE Seatbelt pretensioners are not
designed to activate in minor impacts
or in rear impacts.
 Pretensioners are designed to func-
tion on a one-time-o nly basis. In the
event that a pretensioner is activated,
both the driver’s and front passenger’s
seatbelt retractor assemblies should
be replaced only by an authorized
SUBARU dealer. When replacing
seatbelt retractor assemblies, use only
genuine SUBARU parts.
 If a seatbelt that has a seatbelt
pretensioner does not retract or cannot
be pulled out due to a malfunction or
activation of the pretensioner, contact
your SUBARU dealer as soon as
possible.
 If the seatbelt retractor assembly or
surrounding area has been damaged,
contact your SUBARU dealer as soon
as possible.
CAUTION
 Keep the belts free of polishes,
oils, chemicals and particularly

the occupants should sit in an
upright position with their
seatbelts properly fastened.
Refer to "Seatbelts" P39. Do not modify, remove or strike
the seatbelt retractor assemblies
equipped with seatbelt
pretensioners or surrounding
area. This could result in acci-
dental activation of the seatbelt
pretensioners or could make the
system inoperative, possibly
resulting in serious injury. Seat-
belt pretensioners have no user-
serviceable parts. For required
servicing of seatbelt retractors
equipped with seatbelt
pretensioners, consult your
SUBARU dealer.
 When discarding seatbelt
retractor assemblies equipped

■Cooling and Dehumidifying
in High Humidity and Low
Te mperature Weather Condi -
tionUnder certain weather conditions (high
relative humidity, lo w temperatures, etc.)
a small amount of water vapor emission
from the air outlets may be noticed. This
condition is normal and does not indicate
any problem with the air conditioning
system.■ Air Conditioner Compressor
Shut-Off Whe n Engine Is
Heavily LoadedTo improve acceleration and gas mileage,
the air conditio ner compressor is
designed to temporarily shut off during air
conditioner operation whenever the accel-
erator is fully depressed such as during
rapid acceleration or when driving on a
steep upgrade.
■ Refrigerant for Your Climate
Control Syste m1) Air conditioner labelYour air conditioner uses ozone friendly
refrigerant R-1234yf (HFO-1234yf).
Before adding, changing or checking the
refrigerant, check the air conditioner label
in the location shown in the illustration to
confirm the type of refrigerant is used in
your vehicle.
Consult your SUBARU dealer for service.
Repairs needed as a result of using the
wrong refrigerant are not covered under

tain the filter’s dust collection ability.
Under extremely dusty conditions, the
filter should be replaced more frequently.
Have your filter checked or replaced by
your SUBARU dealer. For replacement,
use only a genuine SUBARU air filter kit.NOTEThe filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained.
