CAUTION
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● In the following situations, the engine may be overheating. In this case,
immediately stop the vehicle in a safe place, and check the engine after it
has cooled completely. ( →P. 481)
• Vehicles with a monochrome multi-information display: The engine coolant temperature gauge enters the red zone
• Vehicles with a color multi-inform ation display: The high engine coolant
temperature warning light flashes or illuminates

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.

Maintenance and care
BRZ_U
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. 362)
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. 362)
■ 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 element
Driving with the air cleaner element removed may cause excessive engine
wear due to dirt in the air. Also a backfire could cause a fire in the engine
compartment.

If you think something is wrong
If you notice any of the following symptoms, your vehicle probably
needs adjustment or repair. Contact your SUBARU dealer as soon as
possible.
■Visible symptoms
● Fluid leaks under the vehicle
(Water dripping from the air conditioning after use is normal.)
● Flat-looking tires or uneven tire wear
● Vehicles with a monochrome multi-information display: The
engine coolant temperature gauge needle continually points
higher than normal
● Vehicles with a color multi-information display: The high
engine coolant temperature warning light flashes or illumi-
nates
■ Audible symptoms
● Changes in exhaust sound
● Excessive tire squeal when cornering
● Strange noises related to the suspension system
● Pinging or other noises related to the engine
■ Operational symptoms
● Engine missing, stumbling or running rough
● Appreciable loss of power
● Vehicle pulls heavily to one side when braking
● Vehicle pulls heavily to one side when driving on a level road
● Loss of brake effectiveness, spongy feeling, pedal almost
touches the floor

BRZ_U
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. 481)
As the engine coolant temperature increases, this warning
light will change from flashing to constantly illuminated.

If your vehicle overheats
Correction proceduresStop the vehicle in a safe place and turn off the air condition-
ing system, and then stop the engine.
If you see steam: Carefully lift the hood after the steam subsides.
If you do not see steam: Carefully lift the hood.
After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radia-
tor) for any leaks.
Radiator
Cooling fans
If a large amount of coolant leaks,
immediately contact your
SUBARU dealer.
The following may indicate that your vehicle is overheating.
●Vehicles with a monochrome multi-information display: The
engine coolant temperature gauge ( →P. 199) enters the red
zone or a loss of engine power is experienced (for example, the
vehicle speed does not increase).
Vehicles with a color multi-information display: The high engine
coolant temperature warning light ( →P. 203) flashes or illumi-
nates or a loss of engine power is experienced (for example, the
vehicle speed does not increase).
● Steam comes out from under the hood.

BRZ_UThe coolant level is satisfactory if
it is between the “FULL” and
“LOW” lines on the reservoir.
Reservoir
“FULL”
“LOW”
Radiator cap
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the air conditioning system on to
check that the radiator cooling fans operate and to check for
coolant leaks from the radiator or hoses.
The fans operate when the air conditioning system is turned on
immediately after a cold start. Confirm that the fans are operating by
checking the fan sound and air flow. If it is difficult to check these,
turn the air conditioning system on and off repeatedly.
(The fans may not operate in freezing temperatures.)
If the fans are not operating: Stop the engine immediately and contact your SUBARU
dealer.
If the fans are operating: Have the vehicle inspected at the nearest SUBARU dealer.
