RX350/RX350L_U
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 gasses cause the exhaust pipes and rear bumper diffusers to become quite
hot.
When washing the vehicle, be careful not to touch the pipes and diffusers until they
have cooled sufficiently, as touching hot exhaust pipes and rear bumper diffusers can
cause burns.
■Precautions 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.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wipers may
operate unexpectedly in the following situa-
tions, and may result in hands being caught or
other serious injuries and cause damage to the
wiper blades.
