GS F_OM_OM30G90U_(U)6-1. Maintenance and care
■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.
• 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 your Lexus dealer.
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.
■When cleaning the windshield (vehicles with rain-sensing windshield wipers)
●When the upper part of the windshield where the raindrop sensor is located is
touched by hand
●When a wet rag or similar is held close to the raindrop sensor
●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
Exhaust gases cause the exhaust pipes and rear bumper diffusers to become quite hot.
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)
If the paint of the rear bumper is chipped or scratched, the system may malfunction. If
this occurs, consult your Lexus dealer.
Turn off AUTO mode of the wiper to prevent
the wiper from operating. ( P. 223)
