AFS (vehicles with discharge headlights)AFS (Adaptive Front lighting System) improves visibility at intersections
and on curves by automatically adjusting the direction of light axis of the
headlights according to vehicle speed and the degree of the tire angle
that are controlled by steering input.
Operates at speeds of 6 mph (10 km/h) or higher.
■ Deactivating AFS
Turn the switch OFF to deactivate
AFS.
OFF
ON
■Daytime running light system
To make your vehicle more visible to other drivers, the headlights turn on automati-
cally (at a reduced intensity) whenever the engine is started and the parking brake
is released. Daytime 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 detecting
the level of ambient light and may cause the
automatic headlight control system to mal-
function.

■Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30 seconds
after all doors are closed with the “ENGINE START STOP” switch switched to
ACCESSORY mode or turned OFF. (The light turns off immediately if
the button on the key is pressed after all doors are locked.)
●When only the tail lights come on: The tail lights turn off automatically if the
“ENGINE START STOP” switch is switched to ACCESSORY mode or turned
OFF and driver’s door is opened.
To turn the lights on again, switch to IGNITION ON mode, or turn the light switch
OFF once and then back to the
or position.
■Automatic headlight leveling system (vehicles with discharge headlights)
The level of the headlights is automatically adjusted according to the number of
passengers and the loading condition of the vehicle to ensure that the headlights do
not interfere with other road users.
■If the indicator flashes... (vehicles with discharge headlights)
It may indicate a malfunction in the system. Contact your Lexus dealer.
■Customization that can be configured at Lexus dealer
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features oP. 5 1 1 )
NOTICE
■To prevent battery discharge

■The windshield wiper and washer can be operated when
The “ENGINE START STOP” switch is in IGNITION ON mode.
■Rain drop sensor
●If the temperature of the raindrop sensor is 194qF (90 qC) or higher, or 5 qF
( -1 5 qC) or lower, automatic operation may not occur. In this case, operate
the wipers in any mode other than “AUTO”,
■AUTO mode
If the wiper switch is turned to AUTO position while the “ENGINE START STOP”
switch is in IGNITION ON mode, the wiper will operate once to show that AUTO
mode is activated.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
Wash/wipe operation
Wipers operate automatically.
(With “AUTO” selected, after
operating several times, the wip-
ers operate one more time after
a short delay to prevent drip-
ping.)
●The sensor judges the amount of raindrops.

2-4. Using other driving systems
ES350_UExample of acceleration (when there are no longer vehicles driving
slower than the set speed in the lane ahead): When the speed is set to
62 mph (100 km/h) and the vehicle ahead driving at 50 mph (80 km/
h) is out of the lane
When the vehicle ahead of you executes a lane change, the system slowly
accelerates until the set vehicle speed is reached. The system then returns to
fixed speed cruising.
■Fine adjustment of the set speed
Adjustment of the set speed by the following speed can be made by lightly pressing
the lever up or down and releasing it.
In the constant speed control mode: Approximately 1.0 mph (1.6 km/h)

Canada: Approximately 3 mph (5 km/h)
■Dynamic radar cruise control warning lights, messages and buzzers
Warning lights, messages and buzzers are used to indicate a system malfunction or
to alert you to the need for caution while driving. ( oP. 4 4 9 )
■Dynamic radar cruise control can be set when
●The shift lever is in D or the 4, 5 or 6 range of S.
●Vehicle speed is above approximately 30 mph (50 km/h).
■Accelerating
The vehicle can accelerate normally. After acceleration, the set speed resumes.
However, during vehicle-to-vehicle distance control mode, the vehicle speed may
decrease below the set speed in order to maintain the distance to the vehicle
ahead.
■Automatically canceling vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the follow-
ing situations.
●Vehicle speed falls below 25 mph (40 km/h)
●VSC is activated
●The sensor cannot operate correctly because it is covered in some way.*

CAUTION
●Motorcycles traveling in the same lane
■Conditions under which the vehicle-to-vehicle distance control may not function
correctly
Apply the brakes as necessary in the following conditions as the radar sensor may
not be able to correctly detect vehicles ahead, and an accident may result.
●When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the trunk, etc.)
●When the road curves or when the lanes are narrow
●When steering wheel operation or your position in the lane is unstable
●When the vehicle ahead of you decelerates suddenly
■Handling the radar sensor
Observe the following to ensure the cruise control system can function effectively:
●Keep the sensor and front grille clean at all times.
Clean the sensor and front grille with a soft cloth so you do not mark or damage
them.

sensor or surrounding area is subject to a strong impact, always have the area
inspected and adjusted by a Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille or surrounding area.
●Do not modify or paint the sensor and grille.
■To ensure the radar sensor functions correctly
Do not do the following to the sensor or grille cover as doing so may cause the sen-
sor not to function correctly and could result in an accident.
●Stick or attach anything to them
●Leave them dirty
●Disassemble, subject them to strong shocks
●Modify or paint them
