2023 SUBARU BRZ ECO mode

Towing
324holes, return the plugs to their original
places.■Using a Flat-Bed Truck
This is the best way to transport your
vehicle. Use the following procedures to
ensure safe transportation.
1. Shift the select lever into the “P” posi-
tion for AT models. Sh ift the shift lever into
the 1st position for MT models.
2. Apply the parking brake firmly.
3. Secure the vehicle onto the carrier
properly with safety chains. Each safety
chain should be equally tightened and
care must be taken not to pull the chains
so tightly that the suspension bottoms out.
■ Towing with All Wheels on
the Ground
WARNING
Use the rear tie-down holes only for
downward anchoring. If they are
used to anchor the vehicle in any
other direction, cables may slip out
of the holes, possibly causing a
dangerous situation.

CAUTION
Transport by flat -bed truck may
cause the headlights to become
misaligned. In such a case, have the
headlight alignment checked by a
SUBARU dealer after transporting
the vehicle by flat-bed truck.
WARNING
 Never turn the ignition switch to
the “OFF” position while the
vehicle is being towed because
the steering wheel and the direc-
tion of the wheels will be locked. Remember that the brake booster
and power steering do not func-
tion when the engine is not
running. Because the engine is
turned off, it w ill take greater
effort to operate the brake pedal
and steering wheel.

Maintenance and Service11
– CONTINUED –
11-1. Maintenance ScheduleU.S. models
The scheduled maintenance items
required to be serviced at regular intervals
are shown in the “Warranty and Mainte-
nance Booklet”. For details, read the
separate “Warranty and Maintenance
Booklet”.
Canada models
The scheduled maintenance items
required to be serviced at regular intervals
are shown in the “Warranty and Service
Booklet”. For details, read the separate
“Warranty and Service Booklet”.
Except for U.S. and Canada models
Some items of your vehicle are required to
be serviced at scheduled intervals. For
details about your maintenance schedule,
read the separate “Warranty and Mainte-
nance Booklet”.
11-2. Maintenance Precau -tionsWhen maintenance and service are
required, it is reco mmended that all work
be done by an authorized SUBARU
dealer.
If you perform maintenance and service
by yourself, you should familiarize your-
self with the information provided in this
section on general maintenance and
service for your SUBARU.
Incorrect or incomplete service could
cause improper or unsafe vehicle opera-
tion. Any problems caused by improper
maintenance and service performed by
you are not eligible for warranty coverage.
WARNING
 Always select a safe area when
performing maintenance on your
vehicle. Always be very careful to avoid
injury when working on the
vehicle. Remember that some of
the materials in the vehicle may
be hazardous if improperly used
or handled, for example, battery
acid.
 Your vehicle should only be
serviced by persons fully compe-
tent to do so. Serious personal
injury may result to persons not
experienced in servicing vehi-
cles. Always use the proper tools and
make certain that they are well
maintained. Never get under the vehicle
supported only by a jack. Always
use safety stands to support the
vehicle. Never keep the engine running in
a poorly ventilated area, such as a
garage or other closed areas. Do not smoke or allow open
flames around the fuel or battery.
This will cause a fire. Because the fuel system is under
pressure, replacement of the fuel
filter should be performed only by
your SUBARU dealer. Wear adequate eye protection to
guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly wash
them out with clean water.

Maintenance Precautions
340NOTESUBARU does not endorse the use of
non-SUBARU approved flushing sys-
tems and strongly advises against per-
forming these services on a SUBARU
vehicle. Non-SUBARU approved flush-
ing systems use chemicals and/or sol-
vents which have not been tested or
approved by SUBARU. SUBARU war-
ranties do not cover any part of the
vehicle which is damaged by adding or
applying chemicals and/or solvents
other than those approved or recom-
mended by SUBARU.
■ Before Checking or
Servicing in the Engine
Compartment
■When Checking or Servicing
in the Engine Compartment
Do not tamper wi th the wiring of
the SRS airbag system or seatbelt
pretensioner system, or attempt
to take its connectors apart, as
that may activate the system or it
can render it inoperative. NEVER
use a circuit tester for these
wiring. If your SRS airbag or
seatbelt pretensioner needs
service, consult your nearest
SUBARU dealer. Check the inside of the engine
compartment to see if there are
any cloths and tools left. If they
are left inside, they may be a
cause of malfunction and fire.
WARNING
 Always stop the engine and apply
the parking brake to prevent the
vehicle from moving. Always let the engine cool down.
Engine parts become very hot
when the engine is running and
remain hot for some time after the
engine is stopped. Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire. When the ignition switch is in the
“ON” position, the cooling fan
may operate suddenly even when
the engine is stopped. If your
body or clothes come into
contact with a rotating fan, that
could result in serious injury. To
avoid risk of injury, always turn
the push-button i gnition switch to
the “OFF” position and confirm
that the operation indicator on
the switch is turn ed off. Then take
the access key fob out from the
vehicle.
 Before performing any servicing
on a vehicle equipped with a
remote engine start system
temporarily place that system in
the service mode to prevent it
from unexpectedly starting the
engine.

Clutch Fluid (MT models)
354Visually check the brake fluid level of the
reservoir monthly on the even surface.1) “MAX” level line
2) “MIN” level lineBe sure to check the brake fluid level from
the outside of the reservoir. If the fluid
level is below “MIN”, top up brake fluid to
“MAX”. Use only brake fluid from a sealed
container.
■ Recommended Brake FluidRefer to "Fluids" P383.
11-15. Clutch Fluid (MT models)■ Checking the Fluid Level
Be careful not to spill brake fluid
when adding it. If brake fluid
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If brake fluid gets on the
exhaust pipe, be sure to wipe it
off.

B02107
CAUTION
Never use different brands of brake
fluid together. Also, avoid mixing
DOT 3 and DOT 4 brake fluids even
if they are the same brand.
WARNING
Never let clutch fluid contact your
eyes because clutch fluid can be
harmful to your eyes. If clutch fluid
gets in your eyes, immediately flush
them thoroughly with clean water.
For safety, when performing this
work, wearing eye protection is
advisable.
CAUTION
 Clutch fluid absorbs moisture
from the air. Any absorbed mois-
ture can cause improper clutch
operation. If the vehicle requires frequent
refilling, there may be a leak. If
you suspect a problem, have the
vehicle checked at your SUBARU
dealer. When you add clutch fluid, be
careful not to allow any dirt into
the tank.

Brake Pedal
35611-17. Brake PedalCheck the brake pedal free play and
reserve distance according to the mainte-
nance schedule in the “Warranty and
Maintenance Booklet”.
11-18. Clutch Pedal (MTmodels)Check the clutch pedal free play
according to the maintenance schedule in
the “Warranty and Maintenance Booklet”.
11-19. Replacement of BrakePad and Lining
CAUTION
 If you continue to drive despite
the scraping noise from the
audible brake pad wear indicator,
it will result in the need for costly
brake rotor repair or replacement. It is recommended that you
disconnect the vehicle battery
before replacing the brake pad.
However, it is dangerous to
disconnect the vehicle battery.
We recommend that you have
your SUBARU dealer replace the
brake pad and lining.

If the approved engine oil is unavailable, use the alternative engine oil described on the next page.
▼ Alternative engine oil
If the SUBARU approved oil is unavailable, the following alternative oil can be used.NOTE Each quantity indicated is only a guideline. The necessary quantity for replacement may differ slightly depending on the
temperature and other factors.
 In choosing an oil, you want the proper quality and viscosity, as well as one that will enhance fuel economy. Oils of lower
viscosity provide better fuel economy. However, in hot weather, oil of higher viscosity is required to properly lubricate the
