NOTICE
Repairing or replacing snow tires
Request repairs or replacement of snow tires from Lexus dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion 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 cor-
rectly when tire chains are fitted.
When standing the windshield wipers up
Raise the wipers in line with the windshield. (P. 437)
Failure to do so may result in damage to the wipers and/or the hood.

7226-1. Maintenance and care
GS450h_300h_OM_OM30D53E_(EE)
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 (vehicles with rain-sensing windshield wip-
ers)
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 mal-
function. If this occurs, consult any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
Turn off AUTO mode of the wiper to
prevent the wiper from operating. (P.
285)
If AUTO mode is selected, the wipers
may operate unexpectedly in the follow-
ing situations, and may result in hands
being caught or other serious injuries and
