time running lights are not designed for use

at night.

Headlight control sensor

The sensor may not function properly if an

object is placed on the sensor, or anything

that blocks the sensor is affixed to the wind-

shield.

Doing so interferes with the sensor detect-

ing the level of ambient light and may cause

the automatic headlight system to malfunc-

tion.

Automatic headlight leveling system

The level of the headlights is automatically

adjusted according to the number of pas-

sengers and the loading condition of the

vehicle to ensure that the headlights do not

interfere with other road users.

12-volt battery-saving function

In order to prevent 12-volt the battery of the

vehicle from discharging, if the light switch

When any of the following conditions is
met, while the headlights (low beam)
are on, the cornering lights will addi-
tionally turn on and light up the direc-
tion of movement for the vehicle. This is
to ensure excellent visibility when
either driving at intersections or park-
ing at night.

Cornering light control

The lights illuminate when the vehicle

speed is approximately 30 km/h (19

mph) or less. However, the lights turn off

when the vehicle speed increases to

AHS (Adaptive High-beam
System)

The Adaptive High-beam System
uses a front camera located behind
the upper portion of the windshield
to assess the brightness of the lights
of vehicles ahead, streetlights, etc.,
and automatically controls the
headlight light distribution as nec-
essary.

WARNING

Limitations of the Adaptive High-

beam System

Do not overly rely on the Adaptive High-

beam System. Always drive safely, taking

care to observe your surroundings and

turning the high beams on or off manu-

ally if necessary.

To prevent incorrect operation of the

Adaptive High-beam System

Do not overload the vehicle.

Operating conditions of the Adaptive

High-beam System

When all of the following conditions are

met, the high beams will be turned on

automatically and the system will oper-

ate:

• The vehicle speed is approximately 60

km/h (38 mph) or more.

• The area ahead of the vehicle is dark.

: When the vehicle speed is approximately

60 km/h (38 mph) or more, the area in
the direction that the vehicle is turning
will be illuminated more brightly than
other areas while driving on a curve.

When all of the following conditions are

met, the shaded high beams will turn on

and the distance that the low beams are

projected will be adjusted automatically,

depending on the location of vehicles

ahead:

• The vehicle speed is approximately 60

km/h (38 mph) or more.

• The area ahead of the vehicle is dark.

• There are vehicles ahead with headlights

or tail lights turned on.

If any of the following conditions are met,

the high beams or shaded high beams will

be changed to the low beams automati-

cally:

• The vehicle speed is below approxi-

mately 60 km/h (38 mph).

Front camera detection information

The high beams may not be automatically

changed to the shaded high beams in the

following situations:

• When vehicles ahead 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 beams may be changed to the

shaded high beams if a vehicle ahead that

is using fog lights without its headlights

turned on is detected.

House lights, street lights, traffic signals,

and illuminated billboards or signs and

other reflective objects may cause the

high beams to change to the shaded high

beams, cause the high beams not to

change to the shaded high beams, or

change the area that is not illuminated.

The following factors may affect the

amount of time taken to turn the high

beam on or off, or the speed by which the

areas not illuminated change:

• 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 light distribution control of the head-

lights may change unexpectedly.

Bicycles or similar objects may not be

detected.

In the following situations the system may

not be able to correctly detect the sur-

rounding brightness level. This may cause

the low beams to remain on or the high

beams to flash or dazzle pedestrians or

vehicles ahead. In such a case, it is neces-

sary to manually switch between the high

and low beams.

• When driving in inclement weather

(heavy rain, snow, fog, sandstorms, etc.)

• When the windshield is obscured by fog,

mist, ice, dirt, etc.

• When the windshield is cracked or dam-

aged

• When the front camera is deformed or

dirty

• When the temperature of the front cam-

era is extremely high

• When the surrounding brightness level is

equal to that of headlights, tail lights or

fog lights

• When headlights or tail lights of vehicles

ahead are turned off, dirty, changing

color, or not aimed properly

• When the vehicle is hit by water, snow,

dust, etc. from a preceding vehicle

• 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

roads, etc.)

• When frequently and repeatedly taking

curves or driving on a winding road

• When there is a highly reflective object

ahead of the vehicle, such as a sign or

mirror

• When the back of a preceding vehicle is

highly reflective, such as a container on a

truck

• When the vehicle’s headlights are dam-

aged or dirty, or are not aimed properly

• When the vehicle is listing or tilting due to

a flat tire, a trailer being towed, etc.

• When the headlights are changed

between the high beams and low beams

repeatedly in an abnormal manner

• When the driver believes that the high

beams may be flashing or dazzling

pedestrians or other drivers

• When the vehicle is used in an area in

which vehicles travel on the opposite side

of the road of the country for which the

• There are many streetlights on the road

ahead.

: The vehicle speed at which the high

beams are automatically turned on/off
may vary depending on the country for
which the vehicle is approved.

Front camera detection information

The high beams may not be automatically

turned off in the following situations:

• When a vehicle suddenly appears from

AHB (Automatic High
Beam)

The Automatic High Beam uses a

Raindrop sensor (vehicles with rain-

sensing windshield wipers)

The raindrop sensor judges the amount

of raindrops.

An optical sensor is adopted. It may not

strikes the windshield, or if bugs, etc. are

present on the windshield.

If the wiper switch is turned to the

“AUTO” position while the power switch

is in ON, the wipers will operate once to

show that AUTO mode is activated.

If the temperature of the raindrop sensor

is 90°C (194°F) or higher, or -15°C

(5°F) or lower, automatic operation may

not occur. In this case, operate the wipers

in any mode other than AUTO mode.

position using the wiper lever.

Raising the wipers to the service
position

Within approximately 45 seconds of
turning the power switch off, move the
wiper lever to the

position and

hold it for approximately 2 seconds or
more.

The wipers will move to the service posi-

Lifting the windshield wipers

While holding the hook portion

the wiper arm, lift the windshield wiper
from the windshield.

WARNING

Caution regarding the use of wind-

shield wipers in AUTO mode (vehi-

cles with rain-sensing windshield

wipers)

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, etc. 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 the washer fluid tank is empty

Do not operate the switch continually as

the washer fluid pump may overheat.

When a nozzle becomes blocked

In this case, contact any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer.

Do not try to clear it with a pin or other

object. The nozzle will be damaged.
