2-3. Operating the lights and windshield wipers
Turning on the high beam headlightsWith the headlights on, push the
lever forward to turn on the high
beams.
Pull the lever back to the center
position to turn the high beams off.
Pull the lever toward you to turn
on the high beams.
Release to turn them off. You can
flash the high beams with the head-
lights on or off.
■Daytime running light system
●Vehicles with halogen headlights: to make your vehicle more visible to other
drivers, the headlights turn on automatically (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.
Vehicles with discharge headlights: to make your vehicle more visible to other
drivers, the parking lights turn on automatically (at a increased intensity) when-
ever the engine is started and the park ing brake is released. Daytime running
lights are not designed for use at night.
●Compared to turning on th e headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel
economy.
■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 system to malfunction.

immediately if on the key is pressed after both side 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 or
.
■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.
■Customization that can be configured at Lexus dealer
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features  P. 5 8 6 )

■Raindrop sensor (vehicles with the rain-sensing windshield wipers)
●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 the temperature of the raindrop sensor is 194 F (90 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”.
■Outside rear view mirror defogger activa tion linked to windshield wiper opera-
tion
The outside rear view mirror defogger au tomatically turns on when you operate the
windshield wipers.
■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.
■Customization that can be configured at Lexus dealer

(Customizable features  P. 5 8 6 )
CAUTION
■Caution regarding the use of windshield wipers in “AUTO” mode (vehicles with
the rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or the
windshield is subject to vibration in “AUT O” mode. Take care that your fingers or
anything else do not become caught in the windshield wipers.

2-4. Using other driving systems
Driving assist systems
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be aware,
however, that these systems are supplementary and should not be relied
upon too heavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
■Brake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces.
■ TRAC (Traction Control)
Maintains drive power and prevents the rear wheels from spinning when
starting the vehicle or accelerating on slippery roads.
■Hill-start assist control
 P. 220
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

When driving
■ Conditions that may trigger the system even if there is no possibility of collision
●When there is an object by the roadside at the entrance to a curve
●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When driving on an uneven road surface
●When passing an oncoming vehicle on a left-turn
●When your vehicle rapidly closes on the vehicle in front
●When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle’s line of travel.
●When an overhead billboard or other me tallic structure appears to be in the
vehicle’s direct line of travel due to driving on a hill.
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
●When passing through certain toll gates
●When driving on a bridge.
When the system is activated in the situations described above there is also a possi-
bility that the seat belts will retract quickly and the brakes will be applied with a force
greater than normal. When the seat belt is locked in the retracted position, stop the
vehicle in a safe place, release the seat belt and refasten.
■Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in the
sensors being unable to detect obstacles, the pre-collision system will be automati-
cally disabled. In this case, the system will not activate even if there is a collision pos-
sibility.
■When there is a malfunction in the system
Warning lights and/or warning mess ages will turn on or flash. (P. 491, 500)

2-5. Driving information
2
When driving
As shown in the above example, if the number of occupants increases,
the cargo and luggage load equaling the combined weight of the occu-
pants who got on later, by an amount. In other words, if an increase in the
number of occupants causes an excess of the total load capacity (com-
bined weight of occupants plus cargo and luggage load), you must
reduce the cargo and luggage on your vehicle.
CAUTION
■Things that must not be carried in the trunk
The following things may cause a fire if loaded in the trunk.
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failing to do so may result in death or serious injury.
●Do not place cargo or luggage in or on the following locations as the item may
get under the brake or accelerator pedal and prevent the pedals from being
depressed properly, block the driver’s vision, or hit the driver or passengers,
causing an accident.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the package tray
• On the instrument panel
•On the dashboard
●Secure all items in the occupant compartment, as they may shift and injure some-
one during sudden braking, sudd en swerving or an accident.
■Capacity and distribution
●Do not exceed the maximum axle weight ra ting or the total vehicle weight rating.
●Even if the total load of occupant's weight and the cargo load is less than the total
load capacity, do not apply the load unevenly. Improper loading may cause dete-
rioration of steering or braking control which may cause death or serious injury.
