GX460_OM_OM60Q09U_(U)4-3. Operating the lights and wipers
■Daytime running light system
●The daytime running lights illuminate using th
e same lights as the parking lights and illu-
minate brighter than the parking lights.
●To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically when a ll of the following conditions are met. (The
daytime running lights are not designed for use at night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the (type B only), or “AUTO”* position
*: When the surroundings are bright
The daytime running lights rema in on after they illuminate even if the parking brake is
set again.
●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 off and the driver’s door is opened.
●When the headlights are on: A ll 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 once and then back to or . 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.

■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 levelin g system warning light flashes
It may indicate a malfun ction in the system. Contact your Lexus dealer.
■Welcome lighting
If the headlight switch is turned to AUTO and the surrounding area is dark, unlocking the
doors using the smart access system with pu sh-button start or wireless remote control
will turn the parking lights and tail lights on automatically.

■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 the 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 wipe rs 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” mo de. 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 cau sed 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.

●Multi-terrain mode is selected other than OFF.
●The center differential lock/unlock is not completed within 5 seconds while the
dynamic radar cruise control system is on.
If vehicle-to-vehicle distance control drivin g is automatically canceled for any other rea-
son, there may be a malfunction in th e system. Contact your Lexus dealer.
■Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following situations:
