The engine switch is in IGNITION ON mode .
■Raindrop sensor
●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.
●If the wiper is turned to “AUTO” position
while the engine switch is
in IGNITION ON mode ,
the wipers will operat e once to show that
“AUTO” mode is activated.
●If the temperature of the raindrop sensor
is 185°F (85°C) or higher, or -22°F (-
30°C) or lower, automatic operation
may not occur. In this case, operate the
wipers in any mode other than “AUTO”.
■If no windshield washer fluid sprays
Check that the washer nozzles are not
blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
■Front door opening linked windshield
wiper stop function
When “AUTO” is selected and the wind-
shield wipers are operating, if a front door is

wiper operation will resume.
■To protect the windshield wipers
If movement of the windshield wipers is
largely restricted by a foreign object such as
snow, the operation of the windshield wip-
ers may be stopped automatically to pro-
tect the windshield wipe rs. In this case, turn
the windshield wiper switch off and remove
the foreign object, and then use the wind-
shield wipers.
■When stopping the engine tem> in an emergency while driving
If the windshield wipers are operating when
the engine is stopped, the
windshield wipers will operate in high speed
operation. After the vehicle is stopped,
operation will return to normal when the
engine switch is turned to
IGNITION ON mode , or
operation will stop when the driver’s door is
opened.
■Customization
The rain-sensing oper ation setting can be
changed.
(Customizable features:  P.391)
When the windshield wipers are not
being used, they retract to below the
hood. To enable the windshield wipers
to be lifted when parking in cold condi-
tions or when replacing a windshield

the windshield wipers to the service
position using the wiper lever.
■Raising the wipers to the service
position
Within approximately 45 seconds of
turning the engine switch switch> off, move the wiper lever to the
position and hold it for approxi-
mately 2 seconds or more.

tion.

gers or anything else do not become
caught in the windshield wipers.

fluid until the windshield becomes warm.
The fluid may freeze on the windshield
and cause low visibility. This may lead to
an accident, resulting in death or serious
injury.

be caused if the lever is pulled toward

Driving
 Use fluids that are appropriate to
the prevailing outside temperatures.
•Engine oil
• Engine coolant
• Power control unit coolant (LC500h)
•Washer fluid
Have a service technician inspect
the condition of the 12-volt battery.
 Have the vehicle fitted with four
snow tires.
Ensure that all tires are the specified size
and the same brand.
Perform the following according to the
driving conditions:
Do not try to forcibly open a window
or move a wiper that is frozen. Pour
warm water over the frozen area to
melt the ice. Wipe away the water
immediately to prevent it from
freezing.
 When the outside door handle is
frozen, unlock the doors using the
wireless remote control. If the out-
side door handles remain retracted
and do not move even if the doors
are unlocked using the wireless
remote control, pour warm water
over the frozen area to melt the ice
and wipe away the water immedi-
ately to prevent it from freezing. The
outside door handle may not retract
due to ice, however, the outside
door handle will return to the nor-
mal position after the ice melts.
 To ensure proper operation of the
climate control system fan, remove
Winter driving tips

the vehicle in a manner appropriate
to the prevailing weather condi-
tions.
Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air
pressure.
●Do not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
●Use snow tires on all, not just some
wheels.
NOTICE
■Driving with tire chains
Do not fit tire chains. Tire chains may
damage the vehicle body and suspen-
sion, and adversely affect driving perfor-
mance.
■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 attach-
ment of snow tires affects the operation
of the tire pressure warning valves and
transmitters.
