GX 460 _O M_ OM6 0F 6 8U _(U )4-3. Operating the lights and wipers
■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically whenev
er the engine is started and the parking
brake is released with the headlight switch off (type B only) or in the “AUTO” position.
(Illuminate brighter than the parking lights. ) Daytime running lights are not designed for
use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to turning on the headlights, the daytime running light system offers greater
durability and consumes less electricity, so it can help improve fuel economy.
■Headlight control sensor
■Automatic light off system
●When only the tail lights are on: All lights turn off if the engine switch is turned to
ACCESSORY mode or turned of f and the driver’s door is opened.
●When the headlights are on: All lights turn off 30 seconds after a door or the glass
hatch is opened and closed.
To turn the lights on again, turn the engine switch to IGNITION ON mode, or turn the
light switch off once and then back to or .
■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of passen-
gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■If the automatic headlight leveling system warning light flashes
It may indicate a malfunction in the system. Contact your Lexus dealer.
■Welcome lighting
If the headlight switch is turned to AUTO an d the surrounding area is dark, unlocking the
doors using the smart access system with push-button start or wireless remote control
will turn the parking lights an d tail lights on automatically.
■Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: →P. 5 9 4 )
The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than ne
cessary when the engine is not running.

GX 460 _O M_ OM6 0F 6 8U _(U )4-3. Operating the lights and wipers
■Effects of vehicle speed on wiper operation
(vehicles with rain-sensing windshield wip-
ers)
With the settings other than “AUTO” also, the time until drip prevention wiper sweep
occurs is changed depending on vehicle speed.
With the low speed wiper operation selected, wiper operation will be switched from low
speed to intermittent wiper operation only when the vehicle is stationary. (However,
when the sensor sensitivity is adjusted to th e highest level, the mode cannot be switched.)
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the windshield
washer fluid reservoir.
CAUTION
■Caution regarding the use of windshield wipers in “AUTO” mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield is subject to vibration in “AUTO” mode. Take care that your fingers etc. anything
else does not become caught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fl uid until the windshield becomes warm. The
fluid may freeze on the windshield and cause lo w visibility. This may lead to an accident,
resulting in death or serious injury.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may overheat.
■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
Do not try to clear it with a pin or other object. The nozzle will be damaged.

Driving
■Conditions in which the function may not operate correctly
In the following conditions, th e camera sensor may be unable to recognize lane markers
causing the lane departure warning function to operate incorrectly. However, this does
not indicate a malfunction.
●When driving through an area with no lane markers, such as a tollbooth, a crossing or
before a ticket checkpoint
●When driving on a sharp curve
●When lane markers are extremely narrow or extremely wide
●When the vehicle leans to one side an unusual amount due to a heavy load or improper
tire inflation pressure
●When the following distance between your vehicle and the vehicle ahead is extremely
short
●When the lane markers are yellow (These ma y be more difficult for the system to rec-
ognize compared to white markers.)
●When the lane markers are broken, “Botts’ dots”, “Raised pavement marker” or stones
●When the lane markers are on a curb etc.
●When lane markers are obscured or partially obscured by sand, dirt, etc.
●When there are shadows on the road running parallel with lane markers, or if a shadow
covers the lane markers
●When driving on a particularly bright road surface, such as concrete
●When driving on a road surface that is bright due to reflected light
●When driving in a location where the light leve l changes rapidly, such as the entrance to
or exit from a tunnel
●When sunlight or the headlight s of oncoming vehicles are shining directly into the cam-
era lens
●When driving on roads that are branching or merging
●When driving on a road surface that is wet du e to rain, previous rainfall, standing water,
etc.
●When the vehicle experiences strong up-and-down motion such as when driving on an
extremely rough road or on a seam in the pavement
●When headlight brightness at nighttime is reduced due to dirt on the lenses, or when
the headlights are misaligned
●When driving on winding roads or roads that are uneven
●When driving on rough or unpaved roads
■When changing the tires
Depending on the tires used, such as snow tire, etc., sufficient performance may not be
maintainable.
■Warning messages and buzzers for LDA system
