High beam automatic turning on or off conditions

When all of the following conditions are fulfilled, the high beam will be automatically

turned on (after approximately 1 second):
• Vehicle speed is above approximately 21 mph (34 km/h).

• The area ahead of the vehicle is dark.

• There are no vehicles ahead with headlights or tail lights turned on.

• There are few streetlights on the road ahead.

If any of the following conditions are fulfilled, the high beam will be automatically turned

off:
• Vehicle speed drops below approximately 17 mph (27 km/h).

• The area ahead of the vehicle is not dark.

• Vehicles ahead have headlights or tail lights turned on.

• There are many streetlights on the road ahead.

Camera sensor detection information

The high beam may not be automatically turned off in the following situations:
• When oncoming vehicles 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 dividers or

roadside trees

• When vehicles ahead appear from the faraway lane on wide road

• When vehicles ahead have no lights

The high beam may be turned off if a vehicle ahead that is using fog lights without using

the headlights is detected.

House lights, street lights, traffic signals, and illuminated billboards or signs may cause

the high beam to switch to the low beams, or the low beams to remain on.

The following factors may affect the amount of time taken to turn the high beam on or

off:
• 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 operational 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 high beam may be turned on or off when the driver does not expect it.

Bicycles or similar objects may not be detected.

In the situations shown below, the system may not be able to accurately detect sur-

rounding brightness levels. This may cause the low beams to remain on or the high

beams to cause problems for pedestrians, vehicles ahead or other parties. In these

cases, manually switch between the high and low beams.
• In bad weather (rain, snow, fog, sandstorms etc.)

• The windshield is obscured by fog, mist, ice, dirt etc.

• The windshield is cracked or damaged.

• The camera sensor is deformed or dirty.

• The camera sensor temperature is extremely high.

• Surrounding brightness levels are equal to those of headlights, tail lights or fog lights.

• Vehicles ahead have headlights that are either switched off, dirty, are changing color,

or are not aimed properly.

• When driving through an area of intermittently changing brightness and darkness.

• When frequently and repeatedly driving ascending/descending roads, or roads with

rough, bumpy or uneven surfaces (such as stone-paved roads, gravel tracks etc.).

• When frequently and repeatedly taking curves or driving on a winding road.

• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.

• The back of a vehicle ahead is highly reflective, such as a container on a truck.

• The vehicle’s headlights are damaged or dirty.

• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.

• The high beam and low beam are repeatedly being switched between in an abnor-

mal manner.

• The driver believes that the high beam may be causing problems or distress to other

drivers or pedestrians nearby.

Temporarily lowering sensor sensitivity

The sensitivity of the sensor can be temporarily lowered.

Turn the engine switch off while the following conditions are met.
• The headlight switch is in

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.

WARNING

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 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 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

In this case, contact your Lexus dealer. 

Do not try to clear it with a pin or other object. The nozzle will be damaged.

WARNING

When refueling the vehicle

Observe the following precautions while refueling the vehicle. Failure to do so may

result in death or serious injury.

After exiting the vehicle and before opening the fuel door, touch an unpainted metal

surface to discharge any static electricity. It is important to discharge static electricity

before refueling because sparks resulting from static electricity can cause fuel vapors

to ignite while refueling.

Always hold the grips on the fuel tank cap and turn it slowly to remove it. 

A whooshing sound may be heard when the fuel tank cap is loosened. Wait until the

sound cannot be heard before fully removing the cap. In hot weather, pressurized fuel

may spray out of the filler neck and cause injury.

Do not allow anyone that has not discharged static electricity from their body to come

close to an open fuel tank.

Do not inhale vaporized fuel.

Fuel contains substances that are harmful if inhaled.

Do not smoke while refueling the vehicle.

Doing so may cause the fuel to ignite and cause a fire.

Do not return to the vehicle or touch any person or object that is statically charged.

This may cause static electricity to build up, resulting in a possible ignition hazard.

When refueling

Observe the following precautions to prevent fuel overflowing from the fuel tank:

Securely insert the fuel nozzle into the fuel filler neck.

Stop filling the tank after the fuel nozzle automatically clicks off.

Do not top off the fuel tank.

NOTICE

Refueling

Do not spill fuel during refueling.

Doing so may damage the vehicle, such as causing the emission control systems to

operate abnormally or damaging fuel system components or the vehicle’s painted sur-

face.

Situation

Actions

When the area around a camera is

covered with dirt, moisture (fogged

up, covered with condensation, ice,

etc.), or other foreign matter

Using the wiper and A/C function, remove the

dirt and other attached matter. (

P. 408)

When the temperature around the

front camera is outside of the opera-

tional range, such as when the vehi-

cle is in the sun or in an extremely

cold environment

If the front camera is hot, such as after the vehi-

cle had been parked in the sun, use the air con-

ditioning system to decrease the temperature

around the front camera. 

If a sunshade was used when the vehicle was

parked, depending on its type, the sunlight

reflected from the surface of the sunshade

may cause the temperature of the front cam-

era to become excessively high.

If the front camera is cold, such after the vehicle

is parked in an extremely cold environment, use

the air conditioning system to increase the tem-

perature around the front camera. 

The area in front of the front camera

is obstructed, such as when the

hood is open or a sticker is attached

to the part of the windshield in front

of the front camera.

Close the hood, remove the sticker, etc. to

clear the obstruction.

When “Pre-Collision System

Unavailable” is displayed.

PCS (Pre-Collision System)

Pre-collision warning

When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a warn-
ing message will be displayed on the
multi-information display to urge the
driver to take evasive action.

Pre-collision brake assist

When the system determines that the possibility of a frontal collision is high,
the system applies greater braking force in relation to how strongly the brake
pedal is depressed.

The pre-collision system uses a radar sensor and front camera to detect vehi-
cles and pedestrians in front of your vehicle. When the system determines
that the possibility of a frontal collision with a vehicle or pedestrian is high, a
warning operates to urge the driver to take evasive action and the potential
brake pressure is increased to help the driver avoid the collision. If the system
determines that the possibility of a frontal collision with a vehicle or pedes-
trian is extremely high, the brakes are automatically applied to help avoid the
collision or help reduce the impact of the collision.

The pre-collision system can be disabled/enabled and the warning timing can
be changed. (

When the system determines that the possibility of a frontal collision is high,
the system warns the driver. If the system determines that the possibility of a
frontal collision is extremely high, the brakes are automatically applied to help
avoid the collision or reduce the collision speed.

Suspension control (if equipped)

When the system determines that the possibility of a frontal collision is high,
the Adaptive Variable Suspension System (

P. 356) will control the damping

force of the shock absorbers to help maintain an appropriate vehicle posture.

WARNING

Limitations of the pre-collision system

The driver is solely responsible for safe driving. Always drive safely, taking care to

observe your surroundings. 

Do not use the pre-collision system instead of normal braking operations under any

circumstances. This system will not prevent collisions or lessen collision damage or

injury in every situation. Do not overly rely on this system. Failure to do so may lead to

an accident, resulting in death or serious injury.

Although this system is designed to help avoid a collision or help reduce the impact of

the collision, its effectiveness may change according to various conditions, therefore

the system may not always be able to achieve the same level of performance. 

Read the following conditions carefully. Do not overly rely on this system and always

drive carefully.
• Conditions under which the system may operate even if there is no possibility of a

collision: 

P. 242

• Conditions under which the system may not operate properly: 

P. 244

Do not attempt to test the operation of the pre-collision system yourself. 

Depending on the objects used for testing (dummies, cardboard objects imitating

detectable objects, etc.), the system may not operate properly, possibly leading to an

accident.

WARNING

Pre-collision braking

When the pre-collision braking function is operating, a large amount of braking force

will be applied.

If the vehicle is stopped by the operation of the pre-collision braking function, the

pre-collision braking function operation will be canceled after approximately 2 sec-

onds. Depress the brake pedal as necessary.

The pre-collision braking function may not operate if certain operations are per-

formed by the driver. If the accelerator pedal is being depressed strongly or the steer-

ing wheel is being turned, the system may determine that the driver is taking evasive

action and possibly prevent the pre-collision braking function from operating.

In some situations, while the pre-collision braking function is operating, operation of

the function may be canceled if the accelerator pedal is depressed strongly or the

steering wheel is turned and the system determines that the driver is taking evasive

action.

If the brake pedal is being depressed, the system may determine that the driver is tak-

ing evasive action and possibly delay the operation timing of the pre-collision braking

function.

When to disable the pre-collision system

In the following situations, disable the system, as it may not operate properly, possibly

leading to an accident resulting in death or serious injury:

When the vehicle is being towed

When your vehicle is towing another vehicle

When transporting the vehicle via truck, boat, train or similar means of transportation

When the vehicle is raised on a lift with the engine running and the tires are allowed to

rotate freely

When inspecting the vehicle using a drum tester such as a chassis dynamometer or

speedometer tester, or when using an on vehicle wheel balancer

When a strong impact is applied to the front bumper or front grille, due to an accident

or other reasons

If the vehicle cannot be driven in a stable manner, such as when the vehicle has been

in an accident or is malfunctioning

When the vehicle is driven in a sporty manner or off-road

When the tires are not properly inflated

When the tires are very worn

When tires of a size other than specified are installed

When tire chains are installed

When a compact spare tire or an emergency tire puncture repair kit is used

If equipment (snow plow, etc.) that may obstruct the radar sensor or front camera is

temporarily installed to the vehicle

Operational conditions

The pre-collision system is enabled and the system determines that the possibility of a

frontal collision with a vehicle or pedestrian is high.
Each function is operational at the following speeds:

Pre-collision warning:
• Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h). (For

detecting a pedestrian, vehicle speed is between approximately 7 and 50 mph [10

and 80 km/h].)

• The relative speed between your vehicle and the vehicle or pedestrian ahead is

approximately 7 mph (10 km/h) or more.

Pre-collision brake assist: 
• Vehicle speed is between approximately 20 and 110 mph (30 and 180 km/h). (For

detecting a pedestrian, vehicle speed is between approximately 20 and 50 mph

[30 and 80 km/h].)

• The relative speed between your vehicle and the vehicle or pedestrian ahead is

approximately 20 mph (30 km/h) or more.

Pre-collision braking:
• Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h). (For

detecting a pedestrian, vehicle speed is between approximately 7 and 50 mph [10

and 80 km/h].)

• The relative speed between your vehicle and the vehicle or pedestrian ahead is

approximately 7 mph (10 km/h) or more.

The system may not operate in the following situations:

If a battery terminal has been disconnected and reconnected and then the vehicle has

not been driven for a certain amount of time

If the shift lever is in R

If VSC is disabled (only the pre-collision warning function will be operational)

If the low speed four-wheel drive indicator is illuminated (only the pre-collision warning

function will be operational)

Pedestrian detection function

Cancelation of the pre-collision braking

If either of the following occur while the pre-collision braking function is operating, it will

be canceled:

The accelerator pedal is depressed strongly.

The steering wheel is turned sharply or abruptly.

Conditions under which the system may operate even if there is no possibility of a colli-

sion

In some situations such as the following, the system may determine that there is a possi-

bility of a frontal collision and operate.
• When passing a vehicle or pedestrian

• When changing lanes while overtaking a preceding vehicle

• When overtaking a preceding vehicle that is changing lanes

• When rapidly closing on a vehicle ahead

The pre-collision system detects pedestrians

based on the size, profile, and motion of a

detected object. However, a pedestrian may not

be detected depending on the surrounding

brightness and the motion, posture, and angle of

the detected object, preventing the system from

operating properly. (

P. 246)

• When overtaking a preceding vehicle that

is making a left/right turn

• When passing a vehicle in an oncoming

lane that is stopped to make a right/left turn

• When driving on a road where relative

location to vehicle ahead in an adjacent

lane may change, such as on a winding

road

LDA (Lane Departure Alert)

When driving on roads with white (yellow) lines, this function alerts the driver
when the vehicle might depart from its lane.
The LDA system recognizes visible
white (yellow) lines with the camera
sensor on the upper portion of the front
windshield.

Lane departure alert function

When the system determines that
the vehicle might depart from its
lane, a warning is displayed on the
multi-information display, and either
the warning buzzer sounds or the
steering wheel vibrates to alert the
driver.

When the warning buzzer sounds or

the steering wheel vibrates, check

the surrounding road situation and

carefully operate the steering wheel

to move the vehicle back to the cen-

ter of the lane.

Summary of functions

4-5. Using the driving support systems

Vehicle sway warning function

When the vehicle is swaying or
appears as if it may depart from its
lane multiple times, the warning
buzzer sounds and a message is dis-
played on the multi-information dis-
play to alert the driver.

WARNING

Before using LDA system

Do not rely solely upon the LDA system. The LDA system does not automatically drive

the vehicle or reduce the amount of attention that must be paid to the area in front of

the vehicle. The driver must always assume full responsibility for driving safely by pay-

ing careful attention to the surrounding conditions and operating the steering wheel to

correct the path of the vehicle. Also, the driver must take adequate breaks when

fatigued, such as from driving for a long period of time.

Failure to perform appropriate driving operations and pay careful attention may lead to

an accident, resulting in death or serious injury.

To avoid operating LDA system by mistake

When not using the LDA system, use the LDA switch to turn the system off.
