Cleaning and protecting the vehicle exterior
● Working from top to bottom, liberally 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.

● Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is cool.
■Self-restoring coat
The vehicle body has a self-restoring coating 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 contain abrasives.

■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to maintain
the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or brush to
apply the foam. Rub in overlapping circles. Do not use water. Wipe dirty surfaces and let
them dry. Excellent results are obtained by keeping the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water 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.
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehicle, such as on the floor, in the hybrid battery
(traction battery) air vents, and in the trunk.
Doing so may cause the hybrid battery, electrical components, etc. to malfunction or
catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet. ( P. 44)
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)
Do not use polish wax or polish cleaner. The instrument panel may reflect off the wind-
shield, obstructing the driver’s view and leading to an accident, resulting in death or
serious injury.
