6-1. Maintenance and care
WARNING
●If you directly touch the raindrop sen- sor body or if something bumps into the raindrop sensor
■Precautions regarding the exhaust
pipes and rear bumper diffusers
As exhaust gases cause the exhaust
pipes and rear bumper diffusers to become quite hot, do not touch the exhaust pipes and rear bumper diffusers
while the engine is running or immediately after the engine is turned off.
When washing the vehicle, be careful not to touch the exhaust pipes and rear
bumper diffusers until they have cooled sufficiently, as touching hot exhaust pipes and rear bumper diffusers can cause
burns.
■Precaution regarding the rear bumper with Blind Spot Monitor (if equipped)
If the paint of the rear bumper is chipped or scratched, the system may malfunc-
tion. If this occurs, consult any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
NOTICE
■Application of coatings to the vehicle body (vehicles with CFRP parts)
Do not apply any kind of coating to the vehicle body as doing so may damage
the paint or reduce its durability.
■To prevent paint deterioration and corrosion on the body and compo-
nents (aluminum wheels etc.)
●Wash the vehicle immediately in the
following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar, pollen or tree sap is present on the paint surface
• If dead insects, insect droppings or bird droppings are present on the paint surface
• After driving in an area contaminated with soot, oily smoke, mine dust, iron
powder or chemical substances
• If the vehicle becomes heavily soiled
with dust or mud
• If liquids such as benzene and gasoline
are spilled on the paint surface
●If the paint is chipped or scratched, have it repaired immediately.
●To prevent the wheels from corroding, remove any dirt and store in a place
with low humidity when storing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic substances or scrub with a hard brush.
This may damage the surfaces of the lights.
●Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses.
■When using an automatic car wash

neutral detergent diluted to approx-
imately 1%.
Wring out any excess water from
the cloth and thoroughly wipe off
remaining traces of detergent and
water.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or brush to apply the foam. Rub in overlapping cir-
cles. Do not use water. Wipe dirty surfaces and let them dry. Excellent results are obtained by keeping the carpet as dry as
possible.

using a cloth or sponge. Also check the belts periodically for excessive wear, fraying or cuts.
■When cleaning the carpeted portions of
the glove box, console box, etc.
If a strong adhesive tape is used, there is a
possibility that the surface of the carpet could be damaged.
NOTICE
■When using a high-pressure car wash
●When washing the vehicle, do not let
water from the high-pressure washer directly hit the camera, the area around the camera or inside of the out-
side door handles. Due to the shock from high-pressure water, it is possible that the device may not operate nor-
mally.
●Do not bring the nozzle tip close to boots (rubber or resin manufactured cover), connectors or the following
parts. The parts may be damaged if they come into contact with high-pres-sure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts

nents etc. to malfunction or catch fire. LC500h: Do not splash or spill liquid in the vehicle, such as on the floor, on
the rear seats, in the hybrid battery (traction battery) air vents or in the trunk. ( P.68)
Doing so may cause the hybrid battery, electrical components, etc. to mal-function or catch fire.
●Do not get any of the SRS components
or wiring in the vehicle interior wet. ( P.35) An electrical malfunction may cause
the airbags to deploy or not function properly, resulting in death or serious injury.
■Cleaning the interior (especially
instrument panel)

■Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Lexus recommends that maintenance service operations as well as
other inspections and repairs be carried out by authorized Lexus retailer or Lexus authorized repairer, or any reliable repair-
ers. For repairs and services covered by your warranty, please visit an authorized Lexus retailer or repairer, who will use gen-
uine Lexus parts in repairing any difficulties you may encounter. There can also be advantages in utilizing authorized Lexus
retailers or repairers for non-warranty repairs and services, as members of the Lexus network will be able to expertly assist
you with any difficulties you may encounter.
Your Lexus retailer or Lexus authorized
repairer, or any reliable repairer will per- form all of the scheduled maintenance on your vehicle reliably and economically due
to their experience with Lexus vehicles.
Scheduled maintenance should be
performed at specified intervals
according to the maintenance sched-
ule.
For details about maintenance items and
schedules, refer to the “Lexus Service
Booklet” or “Lexus Warranty Booklet”.
What about do-it-yourself mainte-
nance?
Many of the maintenance items are easy to
do yourself if you have a little mechanical
ability and a few basic automotive tools.
Note, however, that some maintenance
tasks require special tools and skills. These
are best performed by qualified techni-
cians. Even if you’re an experienced do-it-
yourself mechanic, we recommend that
repairs and maintenance be conducted by
any authorized Lexus retailer or Lexus
authorized repairer, or any reliable
repairer. Any authorized Lexus retailer or
repairer will keep a record of maintenance,
which could be useful should you ever
require Warranty Service. Should you
choose to select a qualified and equipped
professional other than an authorized
Lexus repairer to service or maintain your
vehicle, we recommend that you request
that a record of maintenance be kept.
■Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs that indicate
service is needed. Some important clues are:
●Engine missing, stumbling or pinging
Maintenance requirements
To ensure safe and economical driv-
ing, day-to-day care and regular
maintenance are essential. Lexus
recommends the following mainte-
nance:
WARNING
■If your vehicle is not properly main-
tained
Improper maintenance could result in
serious damage to the vehicle and possi- ble death or serious injury.
■Handling of the 12-volt battery

Maintenance and care
WARNING
The engine compartment contains many mechanisms and fluids that may move suddenly, become hot, or become elec-
trically energized. To avoid death or seri- ous injury, observe the following precautions.
■When working on the engine com-
partment
●LC500h: Make sure that the “IGNI-
TION ON” on the multi-information display and the “READY” indicator are both off.
●Keep hands, clothing and tools away
from the moving fan and engine drive belt.
●LC500: Be careful not to touch the engine, radiator, exhaust manifold, etc.
right after driving as they may be hot. Oil and other fluids may also be hot.LC500h: Be careful not to touch the
engine, power control unit, radiator, exhaust manifold, etc. right after driv-ing as they may be hot. Oil and other
fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine compartment.
●Do not smoke, cause sparks or expose
an open flame to fuel. Fuel fumes are flammable.
●Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the affected area with clean water imme-
diately. If you still experience discomfort, con-sult a doctor.
■When working near the electric cool-ing fan or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode , the electric cooling fan may automatically
start to run if the air conditioning is on and/or the coolant temperature is high. ( P.323)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from get-
ting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter
removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when the fluid level in the accumulator is
high. If the reservoir needs frequent refilling, it may indicate a serious problem.
