2023 SUBARU BRZ window

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 in spection 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
230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
(MT models) or the brake pedal (AT
models) to switch the power to “OFF”. - If the light had illuminated, try to
start the engine again.
- If the light had been off, press the
push-button ignition switch while
depressing the clutch pedal (MT
models) or the brake pedal (AT
models) more forcefully.
 The engine start procedures may
not function depending on the radio
wave conditions around the vehicle. In
such a case, refer to "Starting Engine"
 P326.
 If the vehicle battery is discharged,
the steering cannot be unlocked.
Charge the battery.
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.

Catalytic Converter
291
Driving Tips8
NOTEDue to the expansion and contraction
of the metals used in the manufacture
of the exhaust system, you may hear a
crackling sound coming from the
exhaust system for a short time after
the engine has been shut off. This
sound is normal.
8-4. Catalytic ConverterThe catalytic converter is installed in the
exhaust system. It serves as catalyst to
reduce HC, CO and NOx in exhaust
gases, thus providing cleaner exhaust. To avoid damage to the catalytic

converter:
 Use only unleaded gasoline. Even a
small amount of leaded gasoline will
damage the catalytic converter.
 Never start the engine by pushing or
pulling the vehicle.
 Avoid racing the engine.
 Never turn off the ig nition switch while
the vehicle is moving.
 Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), have
your vehicle checked and repaired by an
authorized SUBARU dealer.
 Do not apply undercoating or rust
prevention treatment to the heat shield of
catalytic converter and the exhaust
system.
 Do not drive with an extremely low fuel
level.
 If at any time you suspect that
exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open. Keep the trunk lid closed while
driving to prevent exhaust gas
from entering the vehicle.
WARNING
Avoid fire hazards. Do not drive
or park the vehicle anywhere near
flammable materi als (e.g. grass,
paper, rags or leaves), because
the catalytic converter operates
at very high temperatures. Keep everyone and flammable
materials away from the exhaust
pipe while the engine is running.
The exhaust gas is very hot.

Winter Driving
293
Driving Tips8
– CONTINUED –
8-8. Winter Driving■Operation during Cold
WeatherCarry some emergency equipment, such
as a window scraper, a bag of sand,
flares, a small shovel and jumper cables.
Check the battery and cables. Cold
temperatures reduce battery capacity.
The battery must be in good condition to
provide enough power for cold winter
starts.
It normally takes longer to start the engine
in very cold weather conditions. Use an
engine oil of a proper grade and viscosity
for cold weather. Using heavy summer oil
will make it harder to start the engine.
Keep the door locks from freezing by
squirting them with deicer or glycerin.
Forcing a frozen door open may damage
or separate the rubber weather strips
around the door. If the door is frozen, use
hot water to melt the ice, and afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that
contains an antifr eeze solution. Do not
use engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.
If you fill the windshield washer tank with
a fluid with a different concentration from
If all four tires are not the same in
items (a) to (h), serious mechani-
cal damage could be caused to
the drivetrain of the car, and
affect the followings.-Ride-Handling- Braking- Speedometer/Odometer cali-
bration- Clearance between the body
and the tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
 In a rollover crash, an unbelted
person is significantly more likely
to die than a person wearing a
seat belt. The driver and all your
passengers should fasten their
seatbelts before st arting to drive
in order to minimize the chance of
serious injury or death. Do not make sharp turns or quick
maneuvers unless absolutely
unavoidable. Such actions are
dangerous as you may lose
control, possibly resulting in a
rollover which could cause death
or serious injury.
 Whenever strong crosswinds are
present, slow do wn sufficiently to
maintain control of your vehicle. Never to drive through pools and
puddles, or roads flooded with
water. Water entering the engine
air intake or the exhaust pipe or
water splashing onto electrical
parts may damage your vehicle
and may cause it to stall. In this
case, contact your SUBARU
dealer immediat ely. Regardless
of its depth, it can wash away the
ground from under your tires,
resulting in possible loss of trac-
tion and even vehicle rollover.
CAUTION
After driving on gravel roads or
rough roads, check the undercar-
riage of the vehicle body for any
damage, deformation, or paint
removal. If you notice any irregulari-
ties, contact a SUBARU dealer for
an inspection as soon as possible.

Cleaning the Interior
336If your SUBARU is to be parked for a long
time in bright sunlight, it is recommended
that the seats and headrests be covered,
or the windows shaded, to prevent fading
or shrinkage.
You will discover that each leather seat
section will develop so ft folds or wrinkles,
which is characteristic of genuine leather.■ Synthetic Leather UpholsteryThe synthetic leather material used on the
SUBARU may be cleaned using mild soap
or detergent and water, after first vacu-
uming or brushing away loose dirt. Allow
the soap to soak in for a few minutes and
wipe off with a clean, damp cloth.
Commercial foam-type cleaners suitable
for synthetic leather materials may be
used when necessary.
■ Instrument Panel, Console
Panel, Switches, Combina -
tion Meter, and Other Plastic
SurfaceUse a soft, damp cloth to clean the instru-
ment panel, center console, combination
meter panel, and switches.■ Center Information DisplayTo clean the center information display,
wipe it with a silicone cloth or with a soft
cloth. If the monitor is extremely dirty,
clean it with a soft cloth moistened with
neutral detergent then carefully wipe off
any remaining detergent.
CAUTION
Strong cleaning agents such as sol-
vents, paint thinners, window
cleaner or gasoline must never be
used on leather or synthetic interior
materials. Doing so could damage
the surface and cause the color to
deteriorate.
CAUTION
 Do not use organic solvents such
as paint thinners or gasoline, or
strong cleaning agents that
contain those solvents. Doing so
could damage the surface and
cause the color to deteriorate. Do not use chemical solvents that
contain silicone on the vehicle
audio system, electrical compo-
nents of the air-conditioner or
any switches. If silicone adheres
to these parts, it may cause
damage to electrical compo-
nents.
CAUTION
 Do not spray neutral detergent
directly onto the monitor. Doing
so could damage the monitor’s
components. Do not wipe the monitor with a
hard cloth. Doing so could
scratch the monitor. Do not use cleaning fluid that
contains thinner, fuel, or any
other volatile substance. Such
cleaning fluid could erase the
lettering on the switches at the
bottom of the monitor.

Replacement of Wiper Blades
367
Maintenance and Service11
– CONTINUED –
If you fill the windshield washer tank with
a fluid with a different concentration from
the one used previously, purge the old
fluid from the piping between the wind-
shield washer tank and washer nozzles by
operating the washer for a certain period
of time. Otherwise, if the concentration of
the fluid remaining in the piping is too low
for the outside temperature, it may freeze
and block the nozzles.
11-24. Replacement of Wiper BladesGrease, wax, insects, or other material on
the windshield or the wiper blade results in
jerky wiper operation and streaking on the
glass. If you cannot remove the streaks
after operating the windshield washer or if
the wiper operation is jerky, clean the
outer surface of the windshield using a
sponge or soft cloth with a neutral deter-
gent or mild-abrasive cleaner. Do not,
however, use detergent to clean the blade
rubbers. Use only a sponge or soft cloth
(and no neutral deterge nt or mild abrasive
cleaner) when you clean the blade
rubbers. If you wipe the rubber of the
blade strongly, the black coating compo-
nent will peel off, which will cause the
wiper to judder. Also, after wiping it off,
check that the rubber has not come loose.
After cleaning the window glass and wiper
blade rubbers, be sure to rinse them with
clean water. Rinse the window until the
water does not form beads on the glass.
This indicates that the glass is clean.
CAUTION
Never use engine coolant as washer
fluid because it could cause paint
damage.
CAUTION
 Adjust the washer fluid concen-
tration appropriately for the
outside temperature. If the
concentration is inappropriate,
sprayed washer fluid may freeze
on the windshield and obstruct
your view, and the fluid may
freeze in the windshield washer
tank. Be careful foreign matter does
not contaminate the washer fluid
when filling the tank. Contamina-
tion could cause malfunctions,
such as clogging the pump.
 State or local regulations on vola-
tile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle’s paint, wiper blades
or washer system.
CAUTION
 Do not clean the wiper blades
with gasoline or a solvent, such
as paint thinner or benzine. This
will cause deterioration of the
wiper blades.

Tire Information
397
Consumer Information and Reporting Safety Defects13
– CONTINUED –
The vehicle placard shows original
tire size, recommended cold tire
inflation pressure on each tire at
maximum loaded vehicle weight,
seating capacity and loading infor-
mation.▼ Adverse safety consequences
of under-inflation
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to flex severely and to
rapidly become hot. A sharp
increase in temperature could
cause tread separation, and failure
of the tire(s). Possible resulting loss
of vehicle control could lead to an
accident.
▼ Measuring and adjusting air
pressure to achieve proper
inflation
Check and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and
before any long journey. Check the
tire pressures when the tires are
cold. Use a pressure gauge to adjust the tire pressures to the

specific values. Driving even a short
distance warms up the tires and
increases the tire pressures. Also,
the tire pressures are affected by
the outside temperature. It is best to
check tire pressure outdoors before
driving the vehicle. When a tire
becomes warm, t he air inside it
expands, causing the tire pressure
to increase. Be careful not to
mistakenly release air from a warm
tire to reduce its pressure.
■ Glossary of Tire TerminologyAccessory weight
The combined weight (in excess of
those standard items which may be
replaced) of automatic transmis-
sion, power steering, power brakes,
power windows, power seats, radio,
and heater, to the extent that these
items are available as factory-
installed equipment (whether
installed or not).
 Bead
The part of the tire that is made of
steel wires, wrapped or reinforced by ply cords and that is shaped to fit

the rim.
 Bead separation
A breakdown of the bond between
components in the bead.
 Bias ply tire
A pneumatic tire in which the ply
cords that extend to the beads are
laid at alternate an gles substantially
less than 90 degrees to the
centerline of the tread.
 Carcass
The tire structure, except tread and
sidewall rubber which, when
inflated, bears the load.
 Chunking
The breaking away of pieces of the
tread or sidewall.
 Cold tire pressure
The pressure in a tire that has been
driven less than 1 mile or has been
standing for three hours or more.
 Cord
The strands forming the plies in the
tire.
