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

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
warranty.
4-7. Air Filtration SystemYour vehicle’s air conditioning system is
equipped with an air filtration system.
Replace the cabin air filter according to
the replacement schedule found in the
“Warranty and Maintenance Booklet”.
This schedule should be followed to main-
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.

Fuel
223
Starting and Operating7
– CONTINUED –
7-1. Fuel■Fuel RequirementsThe engine is designed to operate using
unleaded gasoline with an octane rating
of 93 AKI (98 RON) or higher .
If unleaded gasoline with an octane
rating of 93 AKI (98 RON) is not available,
unleaded gasoline with an octane rating of
91 AKI (95 RON) may be used with no
detriment to engine durability or
driveability.
However, you may notice a slight
decrease in maximum engine perfor-
mance and you may hear some knocking
(pinging) from the engine while using 91
AKI (95 RON) fuel. Use of 91 AKI (95 RON)
fuel will not affect your warranty
coverage.
▼ Fuel octane rating
Using a gasoline with a lower octane
rating can cause persistent and heavy
knocking, which can damage the engine.
Do not be concerned if your vehicle some-
times knocks lightly when you drive up a
hill or when you accelerate. See your
dealer or a qualified service technician if
you use a fuel with the specified octane
rating and your vehi cle knocks heavily or
persistently.
▽RON
This octane rating is the Research Octane
Number.
▽AKI
This octane rating is the average of the
Research Octane and Motor Octane
numbers and is commonly referred to as
the Anti Knock Index (AKI).
▼ Unleaded gasoline
The neck of the fuel filler pipe is designed
to accept only an unleaded gasoline filler
nozzle. Under no circumstances should
leaded gasoline be used because it will
damage the emission control system and
may impair driveability and fuel economy. ▼
Reformulated gasoline
SUBARU supports the use of reformu-
lated gasoline when available. Reformu-
lated gasoline has been blended to burn
more cleanly and reduce vehicle emis-
sions.
▼ MMT
Some gasoline contains an octane-
enhancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl). If
you use such fuels, your emission control
system performance may deteriorate and
the CHECK ENGINE warning light/
malfunction indicator light may turn on. If
this happens, return to your authorized
SUBARU Dealer for service. If it is deter-
mined that the condition is caused by the
type of fuel used, repairs may not be
covered by your warranty.
▼ Gasoline for cleaner air
Your use of gasoline with detergent addi-
tives will help prevent deposits from
forming in your engi ne and fuel system.
This helps keep your engine in tune and
your emission cont rol system working
properly, and is a way of doing your part
for cleaner air. If you continuously use a
high quality fuel with the proper detergent
and other additives, you should never
CAUTION
Use of a fuel which is low in
quality or use of an inappropriate
fuel additive may cause damage
to the engine and/or fuel system. Some gas stations, particularly
those in high altitude areas, offer
fuels posted as regular octane
gasoline with an octane rating
below 93 AKI (98 RON). Use of
those fuels are not recom-
mended.
BRZ_U.book 223 ページ ２０２２年３月２９日　火曜日　午後３時５９分

Fuel
224need to add any fuel system cleaning
agents to your fuel tank.
Many gasolines are now blended with
materials called oxygenates. Use of these
fuels can also help keep the air cleaner.
Oxygenated blend fuels, such as ethanol
(ethyl or grain alcohol) may be used in
your vehicle, but should contain no more
than 15% ethanol for the proper operation
of your SUBARU.
Do not use any gasoline that contains
more than 15% ethanol, including from
any pump labeled E30, E50 or E85 (which
are only some examples of fuel containing
more than 15% ethanol).
In addition, some gasoline suppliers are
now producing reformulated gasolines,
which are designed to reduce vehicle
emissions. SUBARU approves the use of
reformulated gasoline.
If you are not sure what the fuel contains,
you should ask your service station oper-
ators if their gasolines contain detergents
and oxygenates and if they have been
reformulated to reduce vehicle emissions.
As additional guidance, only use fuels
suited for your vehicle as explained in the
following description.
 Fuel should be unleaded and have an
octane rating no lower than that specified
in this manual. 
Methanol (methyl or wood alcohol) is
sometimes mixed with unleaded gasoline.
Methanol can be used in your vehicle
ONLY if it does not exceed 5% of the fuel
mixture AND if it is accompanied by suffi-
cient quantities of the proper cosolvent
and corrosion inhibitors required to
prevent damage to the fuel system. Do not
use fuel containing methanol EXCEPT
under these conditions.
 If undesirable driveability problems are
experienced and you suspect they may be
fuel related, try a different brand of gaso-
line before seeking service at your
SUBARU dealer.
 Fuel system damage or driveability
problems which result from the use of
improper fuel are not covered under the
SUBARU Limited Warranty.
■ Fuel Filler Lid and Cap▼ Locations of the fuel filler lid▼RefuelingOnly one person should be involved in
refueling. Do not allow others to approach
the area of the vehicl e near the fuel filler
pipe while refueling is in progress.
Be sure to observe any other precautions
that are posted at the service station.
1. Stop the vehicle, turn the ignition
switch to the “OFF” position and turn off all
the other electrical components.
2. Push the rear side of the fuel filler lid.
If the fuel filler lid is locked, perform one of
the operations below.
