or stopped.
●Sounds from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the transmis-sion when the gasoline engine starts or stops, when driving at low speeds, or
during idling.
●Engine sounds may be heard when
accelerating sharply.
●Sounds may be heard due to regenera-
tive braking when the brake pedal is depressed or as the accelerator pedal is released.

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.

Maintenance and care
■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
Do not apply water to the inside of the
engine compartment. Doing so may cause the electrical components etc. to catch fire.

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.
