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

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 detect-

ing the level of ambient light and may cause 

the automatic headlight system to malfunc-

tion.

Automatic light off system

When the headlights are on: The head-

lights and tail lights turn off 30 seconds

ahead.

If any of the following conditions are met, 

the high beams will turn off automatically:

• The vehicle speed is below approxi-

mately 17 mph (27 km/h).

• The area ahead of the vehicle is not dark.

• Vehicles ahead have their headlights or 

tail lights turned on.

• There are many streetlights on the road 

ahead.

Camera sensor detection information

The high beams may not be automatically 

turned off in the following situations:

• When a vehicle suddenly appears from 

around a curve

• When the vehicle is cut in front of by 

another vehicle

• When vehicles ahead cannot be 

detected due to repeated curves, road 

dividers or roadside trees

• When vehicles ahead appear in a far-

away lane on a wide road

• When the lights of vehicles ahead are not 

on

AHB (Automatic High 
Beam)

The Automatic High Beam uses a 
camera sensor located behind the 
upper portion of the windshield to 
assess the brightness of the lights of 
vehicles ahead, streetlights, etc., 
and automatically turns the high 
beams on or off as necessary.

WARNING

Limitations of the Automatic High 

Beam

Do not overly rely on the Automatic High 

Beam. Always drive safely, taking care to 

observe your surroundings and turning

Driving

The high beams may be turned off if a 

vehicle ahead that is using fog lights with-

out its headlights turned on is detected.

House lights, street lights, traffic signals, 

and illuminated billboards or signs and 

other reflective objects may cause the 

high beams to change to the low beams, 

or the low beams to remain on.

The following factors may affect the 

amount of time taken for the high beams 

to turn on or off:

• The brightness of the headlights, fog 

lights, and tail lights of vehicles ahead

• The movement and direction of vehicles 

ahead

• When a vehicle ahead only has opera-

tional 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 in the vehicle

The high beams may turn on or off unex-

pectedly.

Bicycles or similar vehicles may not be 

detected.

In the following situations the system may 

not be able to correctly detect the sur-

rounding brightness level. This may cause 

the low beams to remain on or the high 

beams to flash or dazzle pedestrians or 

vehicles ahead. In such a case, it is neces-

sary to manually switch between the high 

and low beams.

• When driving in inclement weather 

(heavy rain, snow, fog, sandstorms, etc.)

• When the windshield is obscured by fog, 

mist, ice, dirt, etc.

• When the windshield is cracked or dam-

aged

• When the camera sensor is deformed or 

dirty

• When the temperature of the camera 

sensor is extremely high

• When the surrounding brightness level is 

equal to that of headlights, tail lights or 

fog lights

• When headlights or tail lights of vehicles 

ahead are turned off, dirty, changing 

color, or not aimed properly

• When the vehicle is hit by water, snow, 

dust, etc. from a preceding vehicle

• When driving through an area of inter-

mittently changing brightness and dark-

ness

• When frequently and repeatedly driving 

ascending/descending roads, or roads 

with rough, bumpy or uneven surfaces 

(such as stone-paved roads, gravel roads, 

etc.)

• When frequently and repeatedly taking 

curves or driving on a winding road

• When there is a highly reflective object 

ahead of the vehicle, such as a sign or 

mirror

• When the back of a preceding vehicle is 

highly reflective, such as a container on a 

truck

• When the vehicle’s headlights are dam-

aged or dirty, or are not aimed properly

• When the vehicle is listing or titling due to 

a flat tire, a trailer being towed, etc.

• When the headlights are changed 

between the high beams and low beams 

repeatedly in an abnormal manner

• When the driver believes that the high 

beams may be flashing or dazzling 

pedestrians or other drivers

Fuel tank opening for unleaded gasoline

To help prevent incorrect fueling, your vehi-

cle has a fuel tank opening that only accom-

modates the special nozzle on unleaded 

fuel pumps.

Opening the fuel tank cap

The fuel tank of your vehicle has a 
special structure, which requires a 
reduction in fuel tank pressure 
before refueling. After the opener 
switch has been pressed, it will take 
several seconds until the vehicle is 
ready for refueling.

Before refueling the vehicle

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 refu-

eling 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 the filler neck and cause injury.

Do not allow anyone that has not dis-

charged 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 vehi-

cle.

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 noz-

zle automatically clicks off.

Do not top off the fuel tank.

Turn the fuel tank cap slowly and 
remove it, then put it into the holder 
on the fuel filler door.

If the fuel filler door cannot be opened

P.473

After refueling, turn the fuel tank cap 
until you hear a click. Once the cap is 
released, it will turn slightly in the oppo-
site direction.

NOTICE

Refueling

Finish refueling within 30 minutes. If 

more than 30 minutes passes, the 

internal valve closes. In this condition, 

fuel may overflow during the refueling 

process.

Press the fuel filler door opener switch 

again.

Make sure that the fuel filler door lock 

is not pushed by the fuel nozzle boot, 

etc. If the lock is held, the internal valve 

closes and fuel may overflow. To pre-

vent it, press the fuel filler door opener 

switch again.

Do not spill fuel during refueling.

Doing so may damage the vehicle, 

such as causing the emission control 

system to operate abnormally or dam-

aging fuel system components or the 

vehicle’s painted surface.

ronment, use the air conditioning system to 
increase the temperature 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 Radar In Self 
Calibration Unavailable See Owner’s Man-
ual” is displayed.

Check whether there is attached materials 
on the radar sensor and radar sensor cover, 
and if there is, remove it.

Pedestrian alert

When the system determines that 
there is a possibility of a frontal collision 
with a stationary or moving pedestrian 
in front of your vehicle, a message will 
be displayed on the head-up display to 
warn the driver.

Pre-collision warning

When the system determines that the 
possibility of a frontal collision is high, a 
buzzer will sound and a warning mes-
sage 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.

Pre-collision braking

If the system determines that the possi-
bility of a frontal collision is extremely 
high, the brakes are automatically 
applied to help avoid the collision or 
reduce the impact of the collision.

PCS (Pre-Collision System) 
(vehicles with Lexus Safety 
System + A)

The pre-collision system uses a 
front radar sensor and front camera 
to detect vehicles and pedestri-
ans/bicyclists in front of your vehi-
cle and front side radar sensors to 
detect vehicles approaching from 
the front left or right side. When the 
system determines that the possi-
bility of a frontal collision with a 
vehicle or pedestrian/bicyclist 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 deter-
mines that the possibility of a frontal 
collision with a vehicle or pedes-
trian/bicyclist 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 dis-
abled/enabled and the warning tim-
ing can be changed. (

Driving

Intersection right/left turn assis-
tance

If the system determines that there is a 
high possibility of a collision in the fol-
lowing situations, it will assist with 
Pre-collision warning and, if necessary 
Pre-collision braking. Depending on 
the configuration of the intersection, it 
may not be possible to support.

When you turn right/left at an inter-
section and cross the path of an 
oncoming vehicle

When you turn right/left, pedestrian 
is detected in the forward direction 
and estimated to enter your vehi-
cle’s path (bicyclists are not 
detected.)

Active steering assist

If the system determines that the possi-
bility of a collision with an object, such 
as a guardrail, or pedestrian is high, 
even though the brakes are applied, 

and that the collision may be avoidable 
through steering control, the system 
will steer the vehicle automatically to 
help avoid the collision or help reduce 
the impact of the collision.

Active Assist for seat belts (front 
seats only)

If the system determines that the possi-
bility of a frontal collision is high, the 
system will retract the seat belts. Addi-
tionally, the system may retract the seat 
belts if the brakes are applied suddenly 
or control of the vehicle is lost.

Pre-collision seatbacks (front pas-
senger’s seat / power rear seat [if 
equipped])

If the system determines that the possi-
bility of a frontal collision is high, it may 
move the seatbacks of the front pas-
senger’s seat and power rear seats to 
the upright position automatically, if 
reclined.

If a seat is being adjusted, it may not be 
moved by the pre-collision seat function.

Suspension control

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

P.337) will control the damp-

ing 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 col-

lision damage or injury in every situa-

tion. Do not overly rely on this system. 

Failure to do so may lead to an acci-

dent, 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 effective-

ness 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 care-

fully. Do not overly rely on this system 

and always drive carefully.

• Conditions under which the system 

may operate even if there is no possi-

bility of a collision: 

P.217

• Conditions under which the system 

may not operate properly: 

P.219

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, pos-

sibly leading to an accident.

Pre-collision braking

When the pre-collision braking func-

tion is operating, a large amount of 

braking force will be applied.

If the vehicle is stopped by the opera-

tion of the pre-collision braking func-

tion, the pre-collision braking function 

operation will be canceled after 

approximately 2 seconds. Depress the 

brake pedal as necessary.

The pre-collision braking function may 

not operate if certain operations are 

performed by the driver. If the acceler-

ator pedal is being depressed strongly 

or the steering wheel is being turned, 

the system may determine that the 

driver is taking evasive action and pos-

sibly prevent the pre-collision braking 

function from operating.

In some situations, while the pre-colli-

sion braking function is operating, 

operation of the function may be can-

celed if the accelerator pedal is 

depressed strongly or the steering 

wheel is turned and the system deter-

mines that the driver is taking evasive 

action.

If the brake pedal is being depressed, 

the system may determine that the 

driver is taking evasive action and pos-

sibly delay the operation timing of the 

pre-collision braking function.

Active steering assist

The steering wheel may turn automati-

cally when active steering assist is 

operating.

As active steering assist operation will 

be canceled when the system deter-

mines that a collision has been 

avoided, operate the steering wheel as 

necessary.

In the following situations, the system 

may determine that the driver is taking 

evasive action. In this case, the active 

steering assist may not operate or may 

be canceled.

• If the accelerator pedal is being 

depressed strongly or the steering 

wheel is being operated. In this case 

the system may determine that the 

driver is taking evasive action and the 

pre-collision braking may not operate.

WARNING

• In some situations, while the active 

steering assist 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.

• When the active steering assist is 

operating, if the steering wheel is held 

firmly or is operated in the opposite 

direction to that which the system is 

generating torque, the function may be 

canceled.

• If the brake pedal is depressed, the sys-

tem may determine that the driver is 

taking evasive action and the active 

steering assist operation may be 

delayed.

Active Asssit for seat belts

If the Active Assist has operated and the 

seat belts are locked in a retracted posi-

tion, immediately stop the vehicle in a 

safe place, release and retract the seat 

belts to unlock them and then fasten 

them again.

Also, if a seat belt can be loosened, it can 

be unlocked by slightly retracting it with-

out releasing it.

When to disable the pre-collision sys-

tem

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 hybrid system on and the tires are
