*1:Vehicles without a keyless access with push button start system
These lights turn on when the engine switch is turned to the “ON”
position to indicate that a system check is being performed. They
will turn off after the engine is started, or after a few seconds. There
may be a malfunction in a system if a light does not come on, or if
the lights do not turn off. Have the vehicle inspected by your
SUBARU dealer.
Vehicles with a keyless access with push button start system
These lights turn on when the push-button ignition switch is turned
to “ON” mode to indicate that a system check is being performed.
They will turn off after the engine is started, or after a few seconds.
There may be a malfunction in a system if a light does not come on,
or if the lights do not turn off. Have the vehicle inspected by your
SUBARU dealer.
*2: This indicator turns on when the engine coolant temperature is low.
*3: The light flashes to indicate that the system is operating.
*4: When the outside temperature is approximately 37°F (3°C) or lower,
the indicator will illuminate.

Drive information (page 3)
Engine coolant temperature
gauge
Displays the engine coolant tem-
perature.
If the engine coolant temperature
gauge needle/indicator enters the
red zone, a buzzer will sound and
a warning message will be dis-
played.
Engine oil temperature gauge
Displays the engine oil tempera-
ture.
Vo l t m e t e r
Displays the charging voltage.
As voltage displayed may
be different from the actual
battery voltage, use the volt-
meter as a guideline.
●Pressing and holding will turn the range value display on the

Maintenance and care
BRZ_U (A4450BE-A)
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■
When working in the engine compartment
● Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
● Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
● Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric cooling fans or radiator grille
Vehicles without a keyless access with push button start system: Be sure the
engine switch is off. With the engine switch in the “ON” position, the electric
cooling fans may automatically start to run if the air conditioning is on and/or
the coolant temperature is high. ( →P. 366)
Vehicles with a keyless access with push button start system: Be sure the
push-button ignition switch is off. With the push-button ignition switch in
“ON” mode, the electric cooling fans may automatically start to run if the air
conditioning is on and/or the coolant temperature is high. ( →P. 366)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
CAUTION
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air. Also a backfire could cause a fire in the engine compart-
ment.

BRZ_U (A4450BE-A)
Stop the vehicle immediately.
The following warning indicates the possibility of damage to the vehi-
cle that may lead to an accident. Immediately stop the vehicle in a
safe place and contact your SUBARU dealer.
Warning lightWarning light/Details
Charging system warning light Indicates a malfunction in the vehicle’s charging system.
Low engine oil pressure warning light Indicates that the engine oil pressure is too low.
(Flashes or illu- minates in red) High engine coolant temperature warning light (if
equipped)
Indicates that the engine is almost overheating. ( →P. 485)
As the engine coolant temperature increases, this warning
light will change from flashing to constantly illuminated.
