warning light SUBARU BRZ 2022 Manual PDF

Preparing to Drive
228have implemented emission inspection of
the OBDII system.
The inspection of the OBDII system
consists of a visual operational check of
the “ CHECK ENGINE ” warning light/
malfunction indicator light (MIL) and an
examination of the OBDII system with an
electronic scan tool.
 A vehicle passes
the OBDII system
inspection if proper operation of the
“ CHECK ENGINE ” warning light is
observed, there are no stored diagnostic
trouble codes, and the OBDII readiness
monitors are all complete.
 A vehicle fails
the OBDII inspection if
the “ CHECK ENGINE ” warning light is not
properly operating (light is illuminated or is
not working due to a burned out bulb) or
there is one or more diagnostic trouble
codes stored in the vehicle’s computer.
 A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBDII system readiness monitors “ NOT
READY ” is greater than one. If the
vehicle’s battery has been recently
replaced or disconnected, the OBDII
system inspection may indicate that the
vehicle is not ready for the emission test.
Under this condition, the vehicle driver
should be instructed to drive his/her
vehicle for a few days to reset the readi-
ness monitors and return for an emission
re-inspection. 
Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service.
7-3. Preparing to DriveYou should perform the following checks
and adjustments every day before you
start driving.
1. Check that all windows, mirrors, and
lights are clean and unobstructed.
2. Check the appearance and condition
of the tires. Also check tires for proper
inflation.
3. Look under the vehicle for any sign of
leaks.
4. Check that no small animals enter the
engine compartment.
5. Check that the hood and trunk are fully
closed.
6. Check the adjustment of the seat.
7. Check the adjustment of the inside
and outside mirrors.
8. Fasten your seatbelt. Check that your
passengers have fastened their seatbelts.
9. Check the operation of the warning
and indicator lights when the ignition
switch is turned to the “ON” position.
10. Check the gauges, indicator and
warning lights after starting the engine.

Starting and Stopping Engine
230When the warm-up is completed, the
engine speed lowers automatically.
On rare occasions, it may be difficult
to start the engine depending on the
fuel and the usage condition (repeated
driving of a distance in which the
engine has not warmed up suffi-
ciently). In such a case, it is recom-
mended that you change to a different
brand of fuel.
 On rare occasions, transient
knocking may be heard from the
engine when the accelerator is oper-
ated rapidly such as a rapid start-up
and a rapid acceleration. This is not a
malfunction.
 The engine starts more easily when
the headlights, air conditioner and rear
window defogger are turned off.■
Starting Engine NOTE

When pressing the push-button
ignition switch while depressing the
clutch pedal (MT models) or the brake
pedal (AT models): - The engine starter operates for a
maximum of 10 seconds and after
starting the engine, the starter stops
automatically.
- The engine can be started
regardless of the power status.
 If the engine does not start, check
the security indicator light. Then press
the push-button ignition switch
without depressing the clutch pedal
WARNING
 There are some general precau-
tions when starting the engine.
Carefully read the precautions
described in "General Precau-
tions When Starting Engine"

P229.
If the steering lock cannot be
released after the engine has
started, never drive the vehicle.
The steering is still locked, and it
may result in an accident.
CAUTION
If a system malfunction warning
message is displayed on the
combination meter, there may be
a malfunction with the vehicle.
Contact a SUBARU dealer imme-
diately.If a steering lock warning
message is displayed on the
combination me ter after the
engine has started, it means that
the steering is still locked. While
moving the steering wheel right
and left, depress the brake pedal,
and press the push-button igni-
tion switch.
 Do not continue pressing the
push-button ignition switch for
more than 10 seconds. Doing so
could cause a malfunction. If the
engine does not start, stop
pressing the push-button ignition
switch. Instead, press the push-
button ignition switch without
depressing the clutch pedal (MT
models) or the brake pedal (AT
models) to switch the power
status to “OFF”. Wait 10 seconds,
and then press the push-button
ignition switch to start the
engine.

Automatic Transmission
237
Starting and Operating7
– CONTINUED –
■
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. ▼
P (Park)
This position is for parking the vehicle and
starting the engine. In this position, the
transmission is me chanically locked to
prevent the vehicle from rolling freely.
When you park the vehicle, first apply the
parking brake, then shift into the “P” posi-
tion. Do not hold the vehicle with only the
mechanical friction of the transmission.
To shift the select lever from the “P” to any
other position, you should depress the
brake pedal fully then move the select
lever. This prevents the vehicle from
lurching when it is started.
▼R (Reverse)
This position is for backing the vehicle. To
shift from the “N” to “R” position, stop the
vehicle completely then move the lever to
the “R” position.
▼N (Neutral)
This position is for restarting a stalled
engine. In this position, the transmission is
neutral, meaning that the wheels and
transmission are not locked. Therefore,
the vehicle will roll freely, even on the
slightest incline unless the parking brake
or foot brake is applied. ▼
D (Drive)
This position is for normal driving. The
transmission shifts automatically into a
suitable gear according to the vehicle
speed and the acceleration you require.
Also, while driving up and down a hill, the
transmission assists and controls the
driving performance and engine braking
while corresponding to the road grade.
When more acceleration is required in “D”
position, depress the accelerator pedal
fully to the floor and hold that position. The
transmission will automatically downshift.
When you release the pedal, the transmis-
sion will return to the original gear posi-
tion.
To use the manual mode, move the lever
from this position into the manual gate.
If one of the shift paddles behind the
steering wheel is operated while driving in
the “D” position, the transmission will
temporarily switch to the manual mode. In
this mode, you can shift into any gear
702768
WARNING
Do not drive the vehicle with the
select lever in the “N” (neutral)
position. Engine braking has no
effect in this condition and the risk
of an accident is consequently
increased.

Automatic Transmission
240The gear changes once each time the
select lever or a shift paddle is operated.
The selected gear, from “M1” to “M6”, will
be displayed on the combination meter.
When in manual mode, the gear will not
change unless the select lever or a shift
paddle is operated, except in the following
situations.
 When the vehicle speed drops
(downshift only)
 When the engine oil temperature is
high and the engine speed approaches
close to the red zone
If an upshift is attempted while the vehicle
speed is low, the gear will not be changed.NOTE If 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.
 You can perform a skip-shift (for
example, from 4th to 2nd) by operating the shift paddle twice in rapid succes-
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 Tips
NOTE
If 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
CAUTION
Do not place or hang anything on
the shift paddles. Doing so may
result in accidental gear shifting.

Power Steering
243
Starting and Operating7
7-9. Power SteeringPower steering warning lightThe vehicle is equipped with an electric
power steering system. When the ignition
switch is turned to the “ON” position, the
power steering warning light on the combi-
nation meter illuminates to inform the
driver that the warning system is func-
tioning properly. Then, if the engine
started, the warning light turns off to
inform the driver that the steering power
assist is operational.
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.
702778
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.

Braking
2447-10. 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 braking
Remember 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. ▼
Braking when a tire is punctured
Do not depress the brake pedal suddenly
when a tire is punctured. This could cause
a loss of control of the vehicle. Keep
driving straight ahead while gradually
reducing speed. Then slowly pull off the
road to a safe place.
■
Brake System
▼
Two separate circuits
Your vehicle has a dual circuit brake
system. Each circuit works diagonally
across the vehicle. If one circuit of the
brake system should fa il, the other half of
the system still works. If one circuit fails,
the brake pedal will go down much closer
to the floor than usual and you will need to
press it down much harder. And a much
longer distance will be needed to stop the
vehicle.
▼Brake booster
The brake booster uses vacuum pump
system to assist braki ng force. Do not turn
off the engine while driving because that
will turn off the brake booster, resulting in
poor braking power.
The brakes will continue to work even
when the brake booster completely stops
functioning. If this happens, however, you
will have to depress the pedal much harder than normal and the braking
distance will increase.
▼
Supplemental booster function
when vacuum pressure fails
While the ignition switch is turned “ON”
and the engine is running, the supple-
mental booster function operates when
the brake booster performance is
decreased due to insufficient vacuum
boost.
When the brake pedal is depressed while
the supplemental booster function is oper-
ating, an operation sound and brake pedal
vibration may be generated. This is not a
malfunction.
▼Brake assist system
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.
WARNING
Do not be overco nfident about the
brake assist. It is not a system that
brings more braking ability to the
vehicle beyond its braking capabil-
ity. Always use the utmost care
when driving regarding vehicle
speed and safe distance.

ABS (Anti-Lock Brake System)
245
Starting and Operating7
– CONTINUED –
Brake assist is a driver assistance system.
It assists the brake power when the driver
cannot depress the brake pedal strongly
and the brake power is insufficient.
Brake assist generates the brake power
according to the speed at which the driver
depresses the brake pedal.NOTEWhen you depress the brake pedal
strongly or suddenly, the following
phenomena occur. However, even
though these occur, they do not indi-
cate any malfunctions, and the brake
assist system is operating properly.
You might feel that the brake pedal
is applied by lighter force and gener-
ates a greater braking force.
 You might hear the sound of ABS
operating from the engine compart-
ment.
■
Disc Brake Pad Wear
Warning Indicators
The disc brake pad wear warning indica-
tors on the disc brakes give a warning
noise when the brake pads are worn.
If a squeaking or scraping noise is heard
from the disc brakes while braking, imme-
diately have your vehicle inspected by the
nearest SUBARU dealer.
7-11. ABS (Anti-Lock Brake System)
CAUTION
When you need to brake suddenly,
continue depressing the brake
pedal strongly to bring the effect of
the brake assist.
700040
WARNING
Always use the utmost care in driv-
ing – overconfidence because you
are driving with an ABS equipped
vehicle could easily lead to a seri-
ous accident.
CAUTION
 The ABS does not always
decrease stopping distance. You
should always maintain a safe
following distance from other
vehicles.When driving on badly surfaced
roads, gravel roads, icy road, or
over newly fallen snow, stopping
distances may be longer for a
vehicle with the ABS than one
without. When driving under
these conditions, therefore,
reduce your speed and leave
ample distance from other vehi-
cles.

Electronic Brake Force Distribution (EBD) System
246The ABS prevents the lock-up of wheels
which may occur during sudden braking or
braking on slippery road surfaces. This
helps prevent the loss of steering control
and directional stability caused by wheel
lock-up.
When the ABS is operating, you may hear
a chattering noise or feel a slight vibration
in the brake pedal. This is normal when
the ABS operates.■
ABS Self-Check
You may feel a slight shock in the brake
pedal and hear the operating noise of the
ABS from the engine compartment just
after the vehicle is started. This is caused
by an automatic functional test of the ABS
being carried out and does not indicate
any abnormal condition.■
ABS Warning Light
Refer to "ABS Warning Light" P140.
7-12. Electronic Brake Force Distribution (EBD) SystemThe EBD system maximizes the effective-
ness of the brakes by allowing the rear
brakes to supply a greater proportion of
the braking force. It functions by adjusting
the distribution of braking force to the rear
wheels in accordance with the vehicle’s
loading condition and speed.
The EBD system is an integral part of the
ABS and uses some of the ABS compo-
nents to perform its function of optimizing
the distribution of braking force. If any of
the ABS components used by the EBD
function fails, the EBD system also stops
working.
When the EBD system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
and does not indicate a malfunction.
■
EBD System Malfunctions
If a malfunction occurs in the EBD system,
the system stops working and the
following warning lights illuminate simulta-
neously.
 Brake system warning light
 ABS warning light
 Vehicle Stability Control (VSC)
warning light
If the both 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 an SUBARU dealer.
 When you feel the ABS operating,
you should maintain constant
brake pedal pressure. Do not
pump the brake pedal since doing
so may defeat the operation of the
ABS.

Vehicle Stability Control (VSC)/TRAC System
247
Starting and Operating7
– CONTINUED –
7-13. Vehicle Stability Control (VSC)/TRAC System■
Vehicle Stability Control
(VSC) System
In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Stability Control (VSC) system
adjusts the engine’s output and the
wheels’ respective braking forces to help
maintain traction and directional control.
The skid suppression function is designed
to help maintain directional stability by
suppressing the wheels’ tendency to slide
sideways during steering operations. Acti-
vation of this function is indicated by
flashing of the Vehicle Stability Control
(VSC) operation indicator light.NOTE In the following circumstances, the
vehicle may be less stable than it feels
to the driver. The Vehicle Stability
Control (VSC) system may therefore
operate. Such operation does not indi-
cate a system malfunction. - On gravel-covered or rutted
roads
- On unfinished roads
- When the vehicle is towing a
trailer - When the vehicl
e is fitted with
snow tires or winter tires
 Activation of the Vehicle Stability
Control (VSC) system will cause opera-
tion of the steering wheel to feel
slightly different compared to that for
normal conditions.
 It is always important to reduce
speed when approaching a corner,
even if the vehicle is equipped with
Vehicle Stability Control (VSC) system.
 Always turn off th e engine before
replacing a tire as failure to do so may
render the Vehicle Stability Control
(VSC) system unable to operate
correctly.
■
TRAC System
The TRAC system is designed to prevent
spinning of the driving wheels on slippery
road surfaces, thereby helping to maintain
traction and directional control. Activation
of this function is indicated by flashing of
the Vehicle Stability Control (VSC) opera-
tion indicator light. The TRAC system is
also equipped with the brake LSD func-
tion.
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 on, 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.

Vehicle Stability Control (VSC)/TRAC System
248
NOTEThe Vehicle Stability Control (VSC)
system and TRAC system may be con-
sidered normal when the following
conditions occur.
Slight twitching of the brake pedal is
felt.
WARNING
 Directional control and power
may not be achievable while
driving on slippery road surfaces,
even if the TRAC system is oper-
ating. Do not drive the vehicle in
conditions where stability and
power may be lost.Always use the utmost care in
driving – overconfidence
because you are driving with a
Vehicle Stability Control (VSC)
system and TRAC system
equipped vehicle could easily
lead to a serious accident.
CAUTION
Even if your vehicle is equipped
with Vehicle Stability Control
(VSC) system and TRAC system,
winter tires should be used when
driving on snow-covered or icy
roads; in addition, vehicle speed
should be reduced considerably.
Simply having a Vehicle Stability
Control (VSC) system and TRAC
system does not guarantee that
the vehicle will be able to avoid
accidents in any situation.
Activation of the Vehicle Stability
Control (VSC) system and TRAC
system is an indication that the
road being travelled on has a slip-
pery surface; since having
Vehicle Stability Control (VSC)
and TRAC is no guarantee that
full vehicle control will be main-
tained at all times and under all
conditions, its activation should
be seen as a sign that the speed
of the vehicle should be reduced
considerably. Whenever suspension compo-
nents, steering components, or
an axle are removed from a
vehicle equipped with the Vehicle
Stability Control (VSC) system
and TRAC system, have an
inspection of that system
performed by an authorized
SUBARU dealer. The following precautions should
be observed in order to ensure
that the Vehicle Stability Control
(VSC) system and TRAC system
is operating properly.
- All four wheels should be
fitted with tires of the same
size, type, and brand. Further-
more, the amount of wear
should be the same for all four
tires.- Keep the tire pressure at theproper level as shown on the
label attached to the driver’s
side center pillar.- When replacing a flat tire, useonly the specified temporary
spare tire. However, even with
the specified temporary spare
tire, the effectiveness of the
Vehicle Stability Control (VSC)
system and TRAC system will
be reduced.
If non-matching tires are used,
the Vehicle Stability Control
(VSC) system and TRAC system
may not operate correctly.
