couple of times after the washer squirts.
(After operating severa l times, the wipers 
operate once more time after a short delay 
to prevent dripping. However, the dripping 
prevention does not operate while the 
vehicle is moving.)
■The windshield wiper and washer can be 
operated when
The engine switch 
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 
in IGNITION ON mode 
the wipers will operate 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 wash er 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 
opened, the operation  of the windshield 
wipers will be stopped to prevent anyone 
near the vehicle from being sprayed by 
water from the wipers, provided the vehicle 
is stopped. When the  front door is closed, 
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 
If the windshield wipe rs are operating when 
the engine 
windshield wipers will operate in high speed 
operation. After the vehicle is stopped, 
operation will return to normal when the 
engine switch 
IGNITION ON mode 
operation will stop when  the driver’s door is 
opened.
■Customization
The rain-sensing operation setting can be 
changed.

Driving
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 
wiper insert, change the rest position of 
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 
 position and hold it for approxi-
mately 2 seconds or more.
The wipers will move to the service posi-
tion.
■Lifting the windshield wipers
While holding the hook portion   of 
the wiper arm, lift the windshield wiper 
from the windshield.
WARNING
■Caution regarding the use of wind-
shield wipers in “AUTO” mode
The windshield wipers may operate 
unexpectedly if the sensor is touched or 
the windshield is subject to vibration in 
“AUTO” mode. Take care that your fin-
gers or anything else do not become 
caught in the windshield wipers.
■Caution regarding the use of washer 
fluid
When it is cold, do not use the washer 
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.
NOTICE
■When there is no washer fluid spray 
from the nozzle
Damage to the washer fluid pump may 
be caused if the lever is pulled toward 
you and held continually.
■When a nozzle becomes blocked
In this case, contact your Lexus dealer. 
Do not try to clear it with a pin or other 
object. The nozzle will be damaged.

2504-6. Driving tips
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
Carry out the necessary prepara-
tions and inspections before driving 
the vehicle in winter. Always drive 
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.
