Fluid TOYOTA SUPRA 2023 Owners Manual

61-1. NOTES
Advanced technology, e.g. the
use of modern materials and
high-performance electronics,
requires suitable maintenance
and repair work.
If work is performed improperly,
for instance maintenance and
repair, there is a risk of subse-
quent damage and related
safety risks.
Improperly performed work on
the vehicle paint can lead to a
failure or malfunction of compo-
nents, e.g., the radar sensors,
and thereby result in a safety
risk.
Toyota recommends the use of
parts and accessory products
approved by Toyota.
Approved parts and accesso-
ries, and advice on their use and
installation are available from
Toyota.
Toyota parts and accessories
have been tested by Toyota for
their safety and suitability in Toy-
ota vehicles.
Toyota warrants genuine Toyota
parts and accessories.
Toyota does not evaluate
whether each Customize prod-
uct from another manufacturer
can be used with Toyota vehi-cles without presenting a safety
hazard, even if a country-spe-
cific official approval was issued.
Toyota does not evaluate
whether these products are suit-
able for Toyota vehicles under
all usage conditions.
California law requires vehicle
manufacturers provide the fol-
lowing warning:

The use of undiluted windshield
washer concentrate or alco-
hol-based antifreeze can lead to
incorrect readings at tempera-
tures below +5°F/-15°C.This chapter describes all stan-
dard, country-specific and
optional features offered with
the series. It also describes fea-
tures and functions that are not
necessarily available in your
vehicle, e.g., due to the selected
options or country versions. This
also applies to safety-related
functions and systems. When
using these functions and sys-
tems, the applicable laws and
regulations must be observed.
The maintenance system pro-
vides service notifications and
thereby provides support in
maintaining road safety and the
operational reliability of the vehi-
cle.
In some cases, scopes and
intervals of the maintenance
system may vary according to
the country version. Replace-
ment work, spare parts, fuels
and lubricants, and wear materi-
als are calculated separately.
Further information is available
from a Toyota dealer.
NOTICE
Silicon-containing additives in the
washer fluid for the water-repel-
ling effect on the windows can
lead to damage to the washing
system. There is a risk of damage
to property. Do not add sili-
con-containing additives to the
washer fluid.
NOTICE
Mixing different windshield
washer concentrates or antifreeze
can damage the washing system.
There is a risk of damage to prop-
erty. Do not mix

recommendation using sensors
and special algorithms that take
into account the driving condi-
tions of the vehicle.
The system makes it possible to
adapt the amount of mainte-
nance corresponding to your

Information on service notifica-
tions, refer to page 147, can be
displayed on the Control Dis-
play.
Storage periods during which
the vehicle battery was discon-
nected are not taken into
account.
If this occurs, have a Toyota
dealer update the time-depen-
dent maintenance procedures,
such as checking brake fluid
and, if necessary, changing the
engine oil and the microfil-
ter/activated-charcoal filter.Please consult “Owner's War-
ranty Information Booklet” or
“Owner's Manual Supplement”
for additional information on ser-
vice and maintenance work.
The manufacturer of your vehi-
cle recommends that mainte-
nance and repair be performed
by a Toyota dealer. Records of
regular maintenance and repair
work should be retained.
Scheduled maintenance should
be performed at specified inter-
vals according to the mainte-
nance schedule.

Remove dust from the leather
regularly, using a cloth or vac-
uum cleaner.
Otherwise, particles of dust and
road grime chafe in pores and
folds, and lead to increased
wear and premature degrada-
tion of the leather surface.
To guard against discoloration,
such as from clothing, clean
leather and provide leather care
roughly every two months.
Clean light-colored leather more
frequently because soiling on
such surfaces is substantially
more visible.
Use leather care products; oth-
erwise, dirt and grease will grad-
ually break down the protective layer of the leather surface.
Clean synthetic leather regularly
with a damp microfiber cloth or
vacuum cleaner.
Otherwise, dust and road grime
particles will rub into pores and
folds, causing significant abra-
sion and premature degrada-
tion of the surface.
In case of major soiling, use a
moist soft sponge or microfiber
cloth with suitable interior clean-
ers.
Immediately remove aggressive
substances such as sunscreen
to prevent the synthetic leather
from being altered or discolored.
Vacuum the upholstery regularly
with a vacuum cleaner.
If upholstery is very dirty, for
instance with beverage stains,
use a soft sponge or microfiber
cloth with a suitable interior
cleaner.
Clean the upholstery down to
the seams using large sweeping
motions. Avoid rubbing the
material vigorously.
NOTICE
●To prevent the wheels from cor-
roding, remove any dirt and
store in a place with low humid-
ity when storing the wheels.
For the matte finish, pay attention
to the following as well:
●If anything is spilled on a
painted surface, wipe it off as
soon as possible. If spilled
washer fluid or alkaline fluids
are left as is, the paint in the
affected area may deteriorate,
causing blemishing.
●Do not wax or apply coating to
the vehicle. Doing so may
cause a change in the body sur-
face's texture or irregularities in
the paint.
