2386-1. Maintenance and care
RC F Owner's Manual
6-1.Maintenance and care
Unlike a vehicle with a normal clear
coat, special care is necessary to pro-
tect the appearance of a vehicle with a
matte clear coat. (P.247, 251, 252)
 Working from top to bottom, liber-
ally apply water to the vehicle body,
wheel wells and underside of the
vehicle to remove any dirt and dust.
 Wash the vehicle body using a
sponge or soft cloth, such as a
chamois.
 For hard-to-remove marks, use car
wash soap and rinse thoroughly with
water.
 Wipe away any water.
 Wax the vehicle when the water-
proof coating deteriorates.
If water does not bead on a clean surface,
apply wax when the vehicle body is cool.
■CFRP (Carbon Fiber Reinforced Plas-
tic) part (if equipped)
●As the CFRP parts may change color if
they are exposed to ultraviolet rays for
extended periods of time, Lexus recom-
mends that your vehicle be stored in a
place where it will not be exposed to
direct sunlight.
●Do not use wax that contains abrasives.
■Black stainless steel window moldings
The stainless steel window moldings are
made of black oxide co ated stainless steel.
When cleaning the vehicle, do not scrub the
moldings with an abrasive cleaner as their
finish may be damaged or the color may
change.
■Self-restoring coat*
The vehicle body has a self-restoring coat-
ing that is resistant to small surface
scratches caused in a car wash etc.
●The coating lasts for 5 to 8 years from
when the vehicle is delivered from the
plant.
●The restoration time differs depending on
the depth of the scratch and outside tem-
perature.
The restoration time may become shorter
when the coating is warmed by applying
warm water.
●Deep scratches caused by keys, coins,
etc. cannot be restored.
●Do not use wax that contains abrasives.
*: CFRP parts (if equipped) do not have a self-restoring coat.
■Automatic car washes(vehicles without
CFRP parts)
●Fold the mirrors before washing the vehi-
cle. Start washing from the front of the
vehicle. Make sure to extend the mirrors
before driving.
●Wash the vehicle with the active rear
wing retracted. If the vehicle is washed
with the active rear wing raised, depend-
ing on the type of automatic car wash, the
brushes of the automatic car wash may
become stuck on the ac tive rear wing. In
Cleaning and protecting the
vehicle exterior
Perform cleaning in a manner
appropriate to each component
and its material.

Maintenance and care
this case, the active rear wing may not be
washed very well or may even be
scratched or damaged.
●Brushes used in automatic car washes
may scratch the vehi cle surface, parts
(wheel, etc.) and harm your vehicle’s
paint.
■Automatic car washes(vehicles with
CFRP parts)
Do not use an automatic car wash as they
may scratch the CFRP parts and damage
their finish or damage the fixed rear wing.
■High pressure car washes
As water may enter the cabin, do not bring
the nozzle tip near the gaps around the
doors or perimeter of the windows, or spray
these areas continuously.
■When using a car wash
If the door handle becomes wet while the
electronic key is within the effective range,
the door may lock and unlock repeatedly. In
that case, follow the following correction
procedures to wash the vehicle:
●Place the key in a position 6 ft. (2 m) or
more separate from the vehicle while the
vehicle is being washed. (Take care to
ensure that the key is not stolen.)
●Set the electronic key to battery-saving
mode to disable the smart access system
with push-button start. ( P.98)
■Wheels and wheel ornaments (vehicles
without matte black painted wheels)
●Remove any dirt immediately by using a
neutral detergent.
●Wash detergent off with water immedi-
ately after use.
●To protect the paint from damage, make
sure to observe the following precau-
tions.
• Do not use acidic, al kaline or abrasive
detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after driving or park-
ing in hot weather
■Wheels and wheel ornaments (vehicles
with matte black painted wheels)
As matte black painted wheels require dif-
ferent cleaning method s than conventional
aluminum wheels, be sure to observer the
following. For details, consult your Lexus
dealer.
●Remove dirt using water. If the wheels are
excessively dirty, use a sponge or soft
cloth dampened with a diluted neutral
detergent to remove the dirt.
●When using detergent, make sure to
rinse it off with water immediately. Then
use a soft cloth to wipe off the water.
●To prevent the matte black paint from
being damaged, make sure to observe
the following precautions:
• Do not scrub or polish the wheels using a brush or dry cloth.
• Do not use any wheel coatings or abra-
sive detergents.
• When using an automatic car wash, dis- able/do not select t he wheel brush func-
tion(if such an option is available).
• Do not use a high pressure pressure washer or steam cleaner.
• Do not use detergent on the wheels when they are hot, such as after driving or park-
ing in hot weather.
■Diffuser (Vehicles with titanium muf-
flers)
The cleaning method for the diffuser on
vehicles with titanium mufflers differs from
that for normal diffusers.
●When using detergent, make sure to
rinse it off with water immediately. Then
use a soft cloth to wipe off the water.
●To prevent the diffuser from being dam-
aged, make sure to observe the following
precautions:
• Do not scrub or polish the diffuser using a brush or dry cloth.
• Do not apply any ceramic coatings or use abrasive detergents.

RC F Owner's Manual
■Brake caliper coating
●When using detergent, use neutral deter-
gent. Do not use hard brushes or abra-
sive cleaners, as they will damage the
paint.
●Do not use detergent on the brake cali-
pers when they are hot.
●Wash detergent off immediately after
use.
■Brake pads and calipers
Rust may form if the vehicle is parked with
wet brake pads or disc rotors, causing them
to stick. Before parking the vehicle after it is
washed, drive slowly and apply the brakes
several times to dry the parts.
■Bumpers
Do not scrub with abrasive cleaners.
■Side windows water- repellent coating
●The following precautions can extend the
effectiveness of the water-repellent coat-
ing.
• Remove any dirt, etc. from the side win- dows regularly.
• Do not allow dirt and dust to accumulate
on the windows for a long period.
Clean the windows with a soft, damp cloth
as soon as possible.
• Do not use wax or glass cleaners that contain abrasives when cleaning the win-
dows.
• Do not use any metallic objects to remove condensation build up.
●When the water-repellent performance
has become insufficient, the coating can
be repaired. Contact your Lexus dealer.
■Plated portions
If dirt cannot be removed, clean the parts as
follows:
●Use a soft cloth dampened with an approximately 5% solution of neutral
detergent and water to clean the dirt off.
●Wipe the surface with a dry, soft cloth to
remove any remaining moisture.
●To remove oily deposits, use alcohol wet
wipes or a similar product.
WARNING
■When washing the vehicle
Do not apply water to the inside of the
engine compartment. Doing so may
cause the electrical components, etc. to
catch fire.
■When cleaning the windshield (vehi-
cles with rain-sensing windshield wip-
ers)
Set the wipers to the intermittent wind-
shield wipers. (
P.143)
If AUTO mode is selected, the wipers
may operate unexpectedly in the follow-
ing situations, and may result in hands
being caught or other serious injuries
and cause damage to the wiper blades.
●When the upper part of the windshield
where the raindrop sensor is located is
touched by hand
●When a wet rag or similar is held close
to the raindrop sensor
●If something bumps against the wind-
shield
●If you directly touch the raindrop sen-
sor body or if something bumps into
the raindrop sensor

■Routine tire inflation pressure checks
The tire pressure warning system does not
replace routine tire inflation pressure
checks. Make sure to check tire inflation
pressure as part of your routine of daily
vehicle checks.
■Situations in which the tire pressure
warning system may not operate prop-
