1-5. Refueling
Opening the fuel tank cap
Perform the following steps to open the fuel tank cap:
■Before refueling the vehicle
● Vehicles without a keyless access with push button start sys-
tem: Turn the engine switch off and ensure that all the doors
and windows are closed.
● Vehicles with a keyless access with push button start system:
Turn the push-button ignition switch off and ensure that all the
doors and windows are closed.
● Confirm the type of fuel. ( →P. 7 9 )
■ Opening the fuel tank cap
Pull up the opener to open the
fuel filler lid.
Turn the fuel tank cap slowly
to open.

Closing the fuel tank cap
After refueling, turn the fuel tank
cap until you hear a click. Once
the cap is released, it will turn
slightly in the opposite direction.
Hang the fuel tank cap on the
back of the fuel filler lid.STEP 3
■Fuel types
Unleaded gasoline (93 AKI [98 RON] or higher)
If unleaded gasoline with an octane rating of 93 AKI (98 RON) is not avail-
able, unleaded gasoline with an octane rating of 91 AKI (95 RON) may be
used with no detriment to engine durability or driveability.

WARNING
■Refueling the vehicle
Observe the following precautions while refueling the vehicle.
Failure to do so may result in death or serious injury.
●Do not handle fuel indoors.
● After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.
● Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap.
In hot weather, pressurized fuel may spray out of the filler neck and cause
injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not allow anyone to approach the area of the vehicle near the fuel filler
pipe while refueling is in progress.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.

WARNING
■
When refueling
Observe the following precautions to prevent fuel overflowing from the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck
● Stop filling the tank after the fuel nozzle automatically clicks off
● Do not top off the fuel tank
● Observe other precautions that are posted at the service station.
● Turn the cap to the right until it clicks to ensure that it is fully tightened. If
the cap is not securely tightened, fuel spillage could occur in the event of
an accident, creating a fire hazard.
■ When replacing the fuel cap
Do not use anything but a genuine fuel tank cap designed for your vehicle.
Doing so may cause a fire or other incident which may result in death or seri-
ous injury.
CAUTION
■Refueling
● Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control
system to operate abnormally or damaging fuel system components or the
vehicle's painted surface.
● Never add any cleaning agents to the fuel tank. The addition of a cleaning
agent may cause damage to the fuel system.
● Immediately put fuel in the tank whenever the low fuel warning light illumi-
nates. Engine misfires as a result of an empty tank could cause damage to
the engine. Continuing to operate your vehicle at an extremely low fuel
level may result in a reduction of engine performance.

2-5. Driving information
Cargo and luggage
Capacity and distributionCargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) - (Total weight of occupants)
Steps for Determining Correct Load Limit 
(1)Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle's
placard.
(2)Determine the combined weight of the driver and passengers that will be riding in your vehicle.
(3)Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
(4)The resulting figure equals the available amount of cargo and lug- gage load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will
be five 150 lb passengers in your vehicle, the amount of available
cargo and luggage load capacity is 650 lbs. (1400 - 750 (5 × 150) =
650 lbs.)
(5)Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the avail-
able cargo and luggage load capacity calculated in Step 4.
Take notice of the following information about storage precau-
tions, cargo capacity and load:
● Stow cargo and luggage in the trunk whenever possible.
● Be sure all items are secured in place.
● To maintain vehicle balance while driving, position luggage
evenly within the luggage compartment.
● For better fuel economy, do not carry unnecessary weight.

4-2. Maintenance
BRZ_U (A4450BE-A)
Emission inspection and maintenance (I/M) programs
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system moni-
tors the operation of th e emission control system.
■If the malfunction indicator lamp comes on
The OBD system determines that a problem exists somewhere
in the emission control system. Your vehicle may not pass the I/
M test and may need to be repaired. Contact your SUBARU
dealer to service the vehicle.
■ Your vehicle may not pass the I/M test:
● When the battery is disconnected or discharged
Readiness codes that are set during ordinary driving are
erased.
Also, depending on your driving habits, the readiness codes
may not be completely set.
● When the fuel tank cap is loose
The malfunction indicator lamp comes on as a temporary mal-
function and your vehicle may not pass the I/M test.
■ When the malfunction indicator lamp goes off after several
driving trips
The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.
■ If your vehicle does not pass the I/M test
Contact your SUBARU dealer to prepare the vehicle for re-test-
ing.

■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent refilling, have it checked by your SUBARU dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its
appearance.
●It is normal for the tire inflation pressure to be higher after driving as
heat is generated in the tire. Do not reduce tire inflation pressure after
driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle
is balanced.

Indicates a malfunction in the cruise control system.
■ If the malfunction indicator lamp comes on while driving
First check the following:
● Is the fuel tank empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The malfunction indicator lamp will go off after several driving trips.
If the malfunction indicator lamp does not go off even after several trips, con-
tact your SUBARU dealer as soon as possible.
■ SRS airbag system warning light
→ P. 129
■ Electric power steering warning light (warning buzzer)
The electric power steering warning light may come on and the warning
buzzer may sound when the voltage is low or the voltage drops.
WARNING
■When the electric power steering warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.
