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, a lkaline 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 methods 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 th e 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.

Illustrations in this manual are simpli-
fied for explanation and may not repre-
sent the actual vehicle.
Glossiness of a surface is seen by the
human eyes by a difference in the
amount of light that reflects off the sur-
face.
A surface painted with normal clear
coat is flat and smooth. As the amount
of light that reflects off the surface is
large, the vehicle body will appear
glossy.
A surface painted with a matte clear
coat is slightly uneven due to the added
matting agent. As the light shining on
an uneven surface is diffused signifi-
cantly, the amount of light reflected is
small, making the vehicle body look not
glossy, with a unique texture.
