WA R N I N G
■When washing the vehicle
Do not apply water to the inside of the en gine 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 body or if something bumps into the raindrop
sensor
■Precautions regarding the exhaust pipes
As exhaust gases cause the exhaust pipes to become quite hot, do not touch the
exhaust pipes while the engine is running or immediately after the engine is turned off.
When washing the vehicle, be careful not to touch the exhaust pipes until they have
cooled sufficiently, as touching hot exhaust pipes 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.
Set the wipers to the intermittent windshield
wipers. ( P. 220)
If AUTO mode is selected, 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.
