2023 SUBARU BRZ brake fluid

Warning and Indicator Lights
140■ABS Warning LightThe ABS warning light illuminates
together with the brake system warning
light if the EBD system malfunctions. For
further details of the EBD system malfunc- tion warning, refe
r to "Brake System
Warning Light" P140.
NOTEIf the warning light behavior is as
described in the following conditions,
the ABS may be considered normal.
 The warning light illuminates right
after the engine is started but turns off
immediately, remaining off.
 The warning light remains illumi-
nated after the engine has been
started, but it turns off while driving.
 The warning light illuminates during
driving, but it turns off immediately and
remains off.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warn ing light may illumi-
nate. This is due to the low battery voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will turn off.
■ Brake System
Warning LightThis light has the following functions.
▼ Parking brake warning
The light illuminates with the parking
brake applied while the ignition switch is in
the “ACC” or “ON” position. It turns off
when the parking brake is fully released.
▼ Brake fluid level warningThis light illuminates when the brake fluid
level has dropped to near the “MIN” level
of the brake fluid reservoir with the ignition
switch in the “ON” position and with the
parking brake fully released.
CAUTION
 If any of the following conditions
occur, we recommend that you
have the ABS (Anti-Lock Brake
System) repaired at the first avail-
able opportunity by your
SUBARU dealer.
- The warning light does not
illuminate when the ignition
switch is turned to the “ON”
position.- The warning light illuminates
when the ignition switch is
turned to the “ON” position,
but it does no t turn off even
after starting the vehicle.- The warning light illuminates
during driving.
 When the warning light is on (and
brake system warning light is off),
the ABS function shuts down;
however, the conventional brake
system continues to operate
normally.
WARNING
 Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains illuminated,
have the brakes inspected by a
SUBARU dealer immediately. If at all in doubt about whether the
brakes are operating properly, do
not drive the vehicle. Have your
vehicle towed to the nearest
SUBARU dealer for repair.

Warning and Indicator Lights
141
Instruments and Controls3
– CONTINUED –
If the brake system warning light should
illuminate while driving (with the parking
brake fully released and with the ignition
switch positioned in “ON”), it could be an
indication of leaking of brake fluid or worn
brake pads. If this occurs, immediately
stop the vehicle at the nearest safe place
and check the brake fluid level. If the fluid
level is below the “MIN” mark in the reser-
voir, do not drive the vehicle. Have the
vehicle towed to the nearest SUBARU
dealer for repair.▼ Electronic Brake Force Distribution
(EBD) system warning
If the warning light remains on even
though the parking brake is released, the
brake fluid level may be low or there could
be a problem with the EBD system. Park
the vehicle in a safe place immediately
and contact a SUBARU dealer.
▼ Vacuum pressure system warning
The brake system warning light will illumi-
nate when the vacuum pressure sensor is
malfunctioning or brake booster pressure
is decreasing. If the light continues to illu-
minate for several minutes after starting
the engine, there may be a malfunction in
the vacuum system. In this case, drive the
vehicle carefully and have the system
inspected by a SUBARU dealer.
■ Low Fuel Warning LightThe low fuel warning light illuminates
when the tank is nearly empty approxi-
mately 1.8 US gal (7.0 liters, or 1.5 Imp
gal). It only operates when the ignition
switch is in the “ON” position.■ Door Open IndicatorWhen any of the doors or the trunk lid is
not fully closed, the door open indicator
appears. This function is effective even if
the ignition switch is in the “OFF” or “ACC”
position.
The open door is indicated by the corre-
sponding part of the door open indicator.
Always make sure this indicator does not
appear before you start to drive.■ Power Steering
Warning LightWhile the engine is running, a warning
light illuminates and a buzzer sounds if a malfunction is detected in the electric

power steering system.
NOTEIf the steering wheel is operated in the
following ways, the power steering
control system may temporarily limit
the power assist in order to prevent
the system components, such as the
control computer and drive motor,
from overheating.
 The steering wheel is operated
frequently and turned sharply while the
vehicle is maneuvered at extremely low
speeds, such as while frequently
turning the steering wheel during
parallel parking.
 The steering wheel remains in the
fully turned position for a long period
of time.
At this time, there will be more resis-
tance when steering. However this is
not a malfunction. Normal steering
CAUTION
Promptly put fuel in the tank when-
ever the low fuel warning light illu-
minates. Engine misfires as a result
of an empty tank could cause dam-
age to the engine.
CAUTION
When the power steering warning
light is illuminated, there may be
more resistance when the steering
wheel is operated. Drive carefully to
the nearest SUBARU dealer and
have the vehicle inspected immedi-
ately.

NOTEEngine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.
7-4. Starting and Stopping Engine■Safety PrecautionsRefer to "Safety Precautions"  P94.■Operating Range for Push-
Button Start SystemRefer to "Operating Range for Push-
Button Start System" P125.■ General Precautions When
Starting Engine
NOTEIt may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This
difficulty is caused by the electroni-
cally controlled throttle’s self-diag-
nosis function. To overcome it, keep
the ignition switch in the “ON” position
for approximately 10 seconds before
starting the engine.
 Avoid rapid racing and rapid accel-
eration immediately after the engine
has started.
 After the engine starts, the engine
speed will be kept high.
CAUTION
Small animals trapped in the cool-
ing fan and belt of the engine may
result in a malfunction. Check that
no small animal enters the engine
compartment and under the vehicle
before starting the engine.
WARNING
Never start the engine from
outside the vehicle. It may result
in an accident. Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide
poisoning.
 Do not start the engine near dry
foliage, paper, or other flammable
substances. The exhaust pipe
and exhaust emissions can
create a fire hazard at high
temperatures.
CAUTION
 If the engine is stopped during
driving, the catalyst may overheat
and burn. When starting the engine, be sure
to sit in the driver’s seat.

Automatic Transmission
236NOTEWhen the engine coolant tempera-
ture is still low, the transmission will
shift at higher engine speeds than
when the coolant temperature is suffi-
ciently high in order to shorten the
warm-up time and improve driveability.
The gearshift timing will automatically shift to the normal
timing after the
engine has warmed up.
 Immediately after transmission fluid
is replaced, you may feel that the trans-
mission operation is somewhat
unusual. This results from invalidation
of data which the on-board computer
has collected and stored in memory to
allow the transmission to shift at the
most appropriate times for the current
condition of your vehicle. Optimized
shifting will be restored as the vehicle
continues to be driven for a while.
 Place the shift boot to the original
position after it is lifted. If the shift lever
is operated with the shift boot in the
rolled up position, the shift boot may
have tension and it may disturb the
shift lever operation.
 When the vehicle is idling at high
rpm in order to warm up, and the
vehicle is on a slippery road, the trans-
mission may automatically shift to 2nd
gear for stopping and starting off.
■ Select Lever
: Shift with the brake pedal depressed
and push-button ignition switch in the “ON”
position. When shifting between “P” and “D”,
depress the brake pedal and securely stop
the vehicle before shifting.
The select lever has four positions, “P”,
“R”, “N”, “D” and also has a manual gate
for using the manual mode.NOTETo protect the engine while the select
lever is in the “P” or “N” position, the
engine is controlled so that the engine
speed may not become too high even
if the accelerator pedal is depressed
hard.
 Do not race the engine for more
than 5 seconds in any position
except the “N” or “P” position
when the brake is applied or when
chocks are used in the wheels.
This may cause the transmission
fluid to overheat. Never move the vehicle rearward
by inertia with the select lever set
in a forward driving position or
move the vehicle forward by
inertia with the select lever set in
the “R” position. Doing so may
result in an unexpected accident
or malfunction. When parking the vehicle, first
securely apply the parking brake
and then place the select lever in
the “P” position. Do not park for a
long time with the select lever in
any other position as doing so
could result in a dead battery.

sion.
If the temperature of the transmis-
sion fluid becomes too high, the “AT
OIL TEMP” warning light will illumi-
nate. Immediately stop the vehicle in a
safe place and let the engine idle until
the warning light turns off.▼ Temporary manual mode driving
While driving with the select lever in “D”, if
a shift paddle is operated, the gear can
temporarily be selected. In this case, “M”
and the selected gear number will be
displayed on the combination meter. (If
the engine speed approaches close to the
red zone, an upshift will automatically be
performed.)1) Upshift
2) Downshift
The selected gear, from “M1” to “M6”, will
be displayed on the combination meter.NOTE In the following situations, tempo-
rary manual mode will be cancelled. - When the vehicle speed is low
- When the accelerator pedal is
depressed continuously for a
certain amount of time or more
- When the accelerator pedal is
depressed heavily
- When the select lever is shifted
to a position other than “D”
- When the “+” shift paddle switch
is held down for a period of time
When a downshift is attempted at a
vehicle speed where a downshift is not
possible (when the engine speed
would enter the red zone if a downshift
is performed), the downshift warning
buzzer will sound to inform the driver
that a downshift cannot be performed.■ Driving TipsNOTEIf the accelerator and brake pedals are
depressed at the same time, driving
torque may be restrained. This is not a
malfunction.
 On a road surface where there is a risk
of wheelspin (for example, a snow- or gravel covered road), you can start off

from a standstill safely and easily by first
selecting Snow mode.
 Always apply the foot or parking brake
when the vehicle is stopped in the “D” or
“R” position.
 Make sure to apply the parking brake
when parking your vehicle. Do not hold
the vehicle with only the transmission.
 Do not keep the vehicle in a stationary
position on an uphill grade by using the
“D” position. Use the brake instead.
 The engine may, on rare occasions,
knock when the vehicle rapidly acceler-
ates or rapidly pulls away from a standstill.
This phenomenon does not indicate a
malfunction.

Starting and Operating7
– CONTINUED –
NOTEIf the steering wheel is operated in the
following ways, the power steering
control system may temporarily limit
the power assist in order to prevent
the system components, such as the
control computer and drive motor,
from overheating.
 The steering wheel is operated
frequently and turned sharply while the
vehicle is maneuvered at extremely low
speeds, such as while frequently
turning the steering wheel during
parallel parking.
 The steering wheel remains in the
fully turned position for a long period
of time.
At this time, there will be more resis-
tance when steering. However this is
not a malfunction. Normal steering
force will be restored after the steering
wheel is not operated for a while and the power steering control system has

an opportunity to cool down. However,
if the power steering is operated in a
non-standard way which causes
power assist limitation to occur too
frequently, this may result in a mal-
function of the power steering control
system.
7-10. Braking■ Braking Tips▼ When the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a
result, brake stopping distance will be
longer. To dry the brakes, drive the
vehicle at a safe speed while lightly
depressing the brake pedal to heat up the
brakes.
▼ Use of engine brakingRemember to make use of engine braking
in addition to foot braking. When
descending a grade, if only the foot brake
is used, the brakes may start working
improperly because of brake fluid over-
heating, caused by overheated brake
pads. To help prevent this, shift into a
lower gear to get stronger engine braking.
CAUTION
While the power steering warning
light is illuminated, there may be
more resistance when the steering
wheel is operated. Drive carefully to
the nearest SUBARU dealer and
have the vehicle inspected immedi-
ately.
WARNING
Never rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads.
