2024-5. Using the driving support systems
RC F Owner's Manual
WARNING
●When driving over roads with potholes
or uneven surfaces
■TRAC may not operate effectively
when
Directional control and power may not
be achievable while driving on slippery
road surfaces, even if the TRAC system is
operating. Drive the vehicle carefully in
conditions where stability and power
may be lost.
■Hill-start assist control does not oper-
ate effectively when
●Do not overly rely on hill-start assist
control. Hill-start assist control may
not operate effectively on steep
inclines and roads covered with ice.
●Unlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended
period of time. Do not attempt to use
hill-start assist control to hold the vehi-
cle on an incline, as doing so may lead
to an accident.
■When the TRAC/VSC is activated
The slip indicator light flashes. Always
drive carefully. Re ckless driving may
cause an accident. Exercise particular
care when the indicator light flashes.
■When the TRAC/VSC systems are
turned off
Be especially careful and drive at a speed
appropriate to the road conditions. As
these are the systems to help ensure
vehicle stability and driving force, do not
turn the TRAC/VSC systems off unless
necessary.
■Expert mode precautions
●Do not use on public roads.
●Use only when the road conditions and
safety of the surrounding area can be
ensured.
●Proper use of expert mode requires a
professional level of driving skill. When
using expert mode, always check the
road conditions and surrounding area
and drive more carefully than usual.
■Replacing tires
Make sure that all ti res are of the speci-
fied size, brand, tread pattern and total
load capacity. In addition, make sure that
the tires are inflated to the recom-
mended tire inflat ion pressure level.
The ABS, TRAC and VSC systems will
not function correctly if different tires are
installed on the vehicle.
Contact your Lexus dealer for further
information when replacing tires or
wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or
modifying the suspensi on will affect the
driving assist systems, and may cause a
system to malfunction.

2456-1. Maintenance and care
RC F Owner's Manual
6
Maintenance and care
It is recommended that regular mainte-
nance should be performed for areas
that are frequently touched to maintain
quality.
■Routine maintenance
This maintenance is most effective if
performed regularly (around once per
month).
1 Soak a cloth in lukewarm water
(approximately 104°F [40°C]),
wring it out thoroughly and then
wipe the entire body.
Wipe carefully so that the pile is not dishev-
eled. Be sure to prepare a clean cloth.
Once you have wiped the part with the
cloth, rinse it until it is completely clean
before using the cloth again.
2 Once it has dried, use a lint brush
or the like to comb the pile.
■When cleaning the artificial
leather (Alcantara®)
 If liquid is spilled onto the surface,
apply tissue paper or the like to
absorb the liquid.
 If any substance such as mud or cof-
fee dries and becomes stuck to the
surface, use a lint brush or the like to
lightly brush the dirty area and
remove the substance. Then, it is
recommended to clean the dried
substance from the surface using a
vacuum cleaner.
 For oil-based substances, use a dry
cloth or tissue paper to wipe off the substance as much as possible,
while being careful not to spread it.
If the substance still cannot be
removed, use the following procedure
to remove it.
1 Liquid substances: Soak a cloth in
lukewarm water (approximately
104°F [40°C]), wring it out thor-
oughly and then wipe the dirty area
from the outside inward.
Wipe carefully so that the pile is not dishev-
eled. Be sure to prepare a clean cloth and
use the clean portion of it to clean the sur-
face.
Oil-based substances: Dab a cloth soaked
in benzene, lukewarm water or pure ethyl
alcohol (for drinking) within the dirty area
from the outside inward, and then dab a
dry cloth on the dirty area to absorb the
substance.
2 If the pile on the surface is dishev-
eled, use a lint brush or the like to
lightly brush the surface, and then
allow the surface to dry completely.
■To remove substances adhered to
the pile
To clean dust or other adhered sub-
stances, use a lint brush or the like to
lightly brush the area and remove the
substance. If the substance still cannot
be removed, use adhesive tape to
remove it.

NOTICE
■When driving
Areas that are frequently touched are
more likely to attract dirt. Ensure that
your hands are clean before touching
anything.

2686-4. Do-it-yourself maintenance
RC F Owner's Manual
If you cannot find a leak, have your Lexus
dealer test the cap and check for leaks in
the cooling system.
Check the radiator and condenser and
clear away any foreign objects.
If either of the above parts is extremely
dirty or you are not sure of their condi-
tion, have your vehicle inspected by
your Lexus dealer.
■Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN” lines
on the tank.
■Adding fluid
Make sure to check the fluid type and
prepare the necessary item.
 Fluid type
SAE J1703 or FMVSS No.116 DOT 3
brake fluid
SAE J1704 or FMVSS No.116 DOT 4
brake fluid
Item
Clean funnel
■Brake fluid can absorb moisture from
the air
Excess moisture in the brake fluid can cause
a dangerous loss of braking efficiency. Use
only newly opened brake fluid.
WARNING
■When the engine is hot
Do not remove the engine coolant reser-
voir cap. ( P.337)
The cooling system may be under pres-
sure and may spray ho t coolant if the cap
is removed, causing serious injuries, such
as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor
straight antifreeze. The correct mixture
of water and antifreeze must be used to
provide proper lubrication, corrosion
protection and cooling. Be sure to read
the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to pre-
vent it from damagi ng parts or paint.

■Front passenger detection sensor, seat
belt reminder and warning buzzer
●If luggage is placed on the front passen-
ger seat, the front passenger detection
sensor may cause the warning light to
flash and the warning buzzer to sound
even if a passenger is not sitting in the
seat.
●If a cushion is placed on the seat, the sen-
sor may not detect a passenger, and the
warning light may not operate properly.

First check the following:
●Is the fuel tank empty?
If it is, fill the fuel tank immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving
trips.
If the light does not go off even after several
trips, contact your Lexus dealer as soon as
possible.
■Electric power steering system warning
light (warning buzzer)
When the battery charge becomes insuffi-
cient or the voltage temporarily drops, the
electric power steeri ng system warning
light may come on and the warning buzzer
may sound.
■When the tire pressure warning light
comes on
Check the tire inflation pressure and adjust
to the appropriate level. Pushing the tire
pressure warning reset switch will not turn
off the tire pressure warning light.
■The tire pressure warning light may
come on due to natural causes
The tire pressure warning light may come
on due to natural causes such as natural air
leaks and tire inflation pressure changes
caused by temperature. In this case, adjust-
ing the tire inflation pressure will turn off the
warning light (after a few minutes).
■When a tire is replaced with a spare tire
The spare tire is not equipped with a tire
pressure warning valve and transmitter. If a
tire goes flat, the tire pressure warning light
will not turn off even th ough the flat tire has
been replaced with the spare tire.
■Conditions that the tire pressure warn-
ing system may not function properly
P.274
■If the tire pressure warning light fre-
quently comes on after blinking for 1

dealer.
WARNING
■If both the ABS and the brake system
warning lights remain on
Stop your vehicle in a safe place immedi-
ately and contact your Lexus dealer. The
vehicle will become extremely unstable
during braking, and the ABS system may
fail, which could cause an accident
resulting in death or serious injury.
■When the electric power steering
system warning light comes on
The steering wheel may become
extremely heavy.
When steering wheel operations are
heavier than usual, grip the steering
wheel firmly and operate it using more
force than usual.

comes on
Be sure to observe the following precau-
tions. Failure to do so could cause a loss
of vehicle control and result in death or
serious injury.
Vehicles with a spare tire
●Stop your vehicle in a safe place as
soon as possible. Adjust the tire infla-
tion pressure immediately.
