wing conditions are 
met, the high beam will be automatically 
turned on (after approximately 1 second):
• Vehicle speed is above approximately 21  mph (34 km/h).
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with head-
lights or tail lights turned on.
• There are few streetlights on the road 
ahead.
●If any of the following conditions are met, 
the high beam will be automatically 
turned off:
• Vehicle speed drops below approxi-
mately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have headlights or tail  lights turned on.
• There are many streetlights on the road  ahead.
■Front camera detection information
●The high beam may not be automatically 
turned off in the following situations:
• When oncoming vehicles suddenly  appear from a curve
• When the vehicle is cut in front of by 
another vehicle
• When vehicles ahead are hidden from  sight due to repeated curves, road divid-
ers or roadside trees
• When vehicles ahead appear from the  faraway lane on wide road
• When vehicles ahead have no lights
●The high beam may be turned off if a 
vehicle ahead that is using fog lights with-
out using the headlig hts is detected.
Automatic High Beam
The Automatic High Beam uses an 
in-vehicle front camera to assess 
the brightness of streetlights, the 
lights of vehicle ahead, etc., and 
automatically turns the high beam 
on or off as necessary.
WARNING
■Limitations of the Automatic High 
Beam

●House lights, street lights, traffic signals, 
and illuminated billboards or signs may 
cause the high beam to switch to the low 
beams, or the low beams to remain on.
●The following factors may affect the 
amount of time taken to turn the high 
beam on or off:
• The brightness of headlights, fog lights, 
and tail lights of vehicles ahead
• The movement and direction of vehicles  ahead
• When a vehicle ahead only has opera- tional lights on one side
• When a vehicle ahead is a two-wheeled 
vehicle
• The condition of the road (gradient,  curve, condition of the road surface etc.)
• The number of passengers and amount of  luggage
●The high beam may be turned on or off 
when the driver does not expect it.
●Bicycles or similar objects may not be 
detected.
●In the situations show n below, the system 
may not be able to accurately detect sur-
rounding brightness levels. This may 
cause the low beams to remain on or the 
high beams to cause problems for pedes-
trians, vehicles ahead or other parties. In 
these cases, manually switch between the 
high and low beams.
• In bad weather (rain, snow, fog, sand-
storms etc.)
• The windshield is obscured by fog, mist,  ice, dirt etc.
• The windshield is  cracked or damaged.
• The front camera is deformed or dirty.
• Surrounding brightness levels are equal  to those of headlights, tail lights or fog 
lights.
• Vehicles ahead have headlights or tail 
lights that are either switched off, dirty, 
changing color, or have improperly 
adjusted aim.
• When driving through an area of inter- mittently changing brightness and dark-
ness.
• When frequently and repeatedly driving 
ascending/descending roads, or roads 
with rough, bumpy or uneven surfaces 
(such as stone-paved roads, gravel tracks 
etc.). • When frequently and repeatedly taking 
curves or driving on a winding road.
• There is a highly re flective object ahead 
of the vehicle, such as a sign or a mirror.
• The vehicle’s headlights are damaged or  dirty.
• The vehicle is listing or titling, due to a flat  tire, a trailer being towed etc.
• The driver believes that the high beam 
may be causing problems or distress to 
other drivers or pedestrians nearby.
■Temporarily lowering  sensor sensitivity
The sensitivity of the sensor can be tempo-
rarily lowered.
1 Turn the engine switch 
off while the following conditions are 
met.
• The headlight swit ch is in   or  .
• The headlight switch  lever is in low beam 
position.
• Automatic High Be am switch is on.
2 Turn the engine switch 
to IGNITION ON mode 
3 Within 60 seconds after  2, repeat pull-
ing the headlight switch lever to the 
original position then pushing it to the 
high beam position quickly 10 times, 
then leave the lever in high beam posi-
tion.
4 If the sensitivity is changed, the Auto-
matic High Beam indicator turns on and 
off 3 times.
Automatic High Beam (headlights) may

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.

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.
