NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attachment of snow tires affects the operation of
the tire pressure warning valves and transmitters.
■Fitting tire chains (vehicles with front and rear tires of the same size except for
the vehicles with LDH and 19 inch tires)
The tire pressure warning valves and transmitters may not function correctly when
tire chains are fitted.
■When standing the windshield wipers up
Raise the wipers in line with the windshield. (→P. 3 2 1 )
Failure to do so may result in damage to the wipers and/or the hood.

6-1. Maintenance and care
CAUTION
■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
●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
Exhaust gases cause the exhaust pipes to become quite hot.
When washing the vehicle, be careful not to touch the 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 malfunc-
tion. If this occurs, consult your Lexus dealer.
Turn off AUTO mode of the wiper to prevent
the wiper from operating. ( →P. 223)
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.
