6-1. Maintenance and care
6-1.Maintenance and care
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.
●Do not use automatic car washes as they may scratch the CFRP parts and damage
the paint.
■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.
■Cleaning the areas with metal accents
Do not use baking soda (sodium bicarbon-
ate) and wax that contains abrasives.
■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 active rear wing. In
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 vehicle body and dam-
age the paint.
■High pressure car washes
●Do not allow the nozzles of the car wash
to come within close proximity of the win- dows.
●Before using the car wash, check that the fuel filler door on your vehicle is closed properly.
Cleaning and pr otecting the
vehicle exterior
Perform cleaning in a manner
appropriate to each component
and its material.

■Notes for a smart entry & start system
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 2 m (6 ft.) 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 entry & start
system. ( P.124)
■Aluminum 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, alkaline 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
■Brake caliper coating
●When using detergent, use neutral deter-gent. Do not use hard brushes or abra-
sive cleaners, as they will damage the coating.
●Do not use detergent on the brake cali-pers when they are hot.
●Wash detergent off immediately after use.
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-repellent coating
●The following precautions can extend the effectiveness of the water-repellent coat-ing.
• Remove any dirt, etc. from the front side windows 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 any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer.
WARNING
■When washing the vehicle

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
Set the wiper switch to the off position.
If the wiper switch is in AUTO, the wipers may operate and the wiper blades may be damaged.

6-3. Do-it-yourself maintenance
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose the fabric,
and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be
properly repaired due to the size or loca- tion of a cut or other damage
If you are not sure, consult any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if it has sel-
dom or never been used or damage is not obvious.
■Low profile tires (21-inch tires)
Generally, low profile tires will wear more rapidly and tire grip performance will be reduced on snowy and/or icy roads when
compared to standard tires. Be sure to use snow tires on snowy and/or icy roads and drive carefully at a speed appropriate for
road and weather conditions.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
Rotate the tires in the order shown.
WARNING
■When inspecting or replacing tires
Observe the following precautions to
prevent accidents. Failure to do so may cause damage to parts of the drivetrain as well as danger-
ous handling characteristics, which may lead to an accident resulting in death or serious injury.
●Do not mix tires of different makes,
models or tread patterns. Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Lexus.
●Do not mix differently constructed
tires (radial, bias-belted or bias-ply tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used
on another vehicle. Do not use tires if you do not know how they were used previously.
NOTICE
■Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the cushion-ing ability of the tires. In addition, driving
on rough roads may cause damage to the tires themselves, as well as the vehi-cle’s wheels and body.
■Low profile tires (21-inch tires)
Low profile tires may cause greater dam- age than usual to the tire wheel when
sustaining impact from the road surface. Therefore, pay attention to the following:
●Be sure to use proper tire inflation pressure. If tires are under-inflated,
they may be damaged more severely.
●Avoid potholes, uneven pavement, curbs and other road hazards. Failure to do so may lead to severe tire and
wheel damage.
■If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
