■Front side windows water-repellent coating (if equipped)
●The following precautions can extend the effectiveness of the water-repellent coating.
• 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 co ntain abrasives when cleaning the windows.

●If something bumps against the windshield
●If you directly touch the raindrop sensor bo dy or if something bumps into the raindrop
sensor
■Precautions regarding the exhaust pipes and rear bumper diffusers

When washing the vehicle, be careful not to touch the pipes and rear bumper diffusers
until they have cooled sufficiently, as touc hing hot exhaust pipes and rear bumper dif-
fusers can cause burns.
■Precaution regarding the rear bumper with Blind Spot Monitor (if equipped)

this occurs, consult your Lexus dealer.
Turn off AUTO mode of the wiper to prevent
the wiper from operating. ( P. 223)
