are hidden from sight due to repeated

curves, road dividers or roadside trees

●

High beam may be turned off if an

oncoming vehicle that is using fog lights

without using the headlights is detected.

●

House lights, street lights, red traffic sig-

nals, and illuminated billboards or signs

may cause the high beam to turn off.

●

The following factors may affect the

amount of time taken to turn high beam

on or off:

• The brightness of headlights, fog lights,

and tail lights of oncoming and preceding

vehicles

• The movement and direction of oncom-

ing and preceding vehicles

• When a oncoming or preceding vehicle

only has operational lights on one side

• When a oncoming or preceding vehicle

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

●

High beam may be turned on or off when

unexpected by the driver.

●

In the situations below, the system may

not be able to correctly detect the sur-

rounding brightness levels, and may flash

or expose nearby pedestrians to the high

beam. Therefore, you should consider

turning the high beams on or off manually

rather than relying on the Automatic

High Beam system.

• In bad weather (rain, snow, fog, sand-

storms, 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 or tail

lights that are either switched off, dirty,

are changing color, or are not aimed

properly.

• 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

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 titling, due to a flat

tire, a trailer being towed, etc.

• The driver believes that the high beam

may be causing problems or distress to

other drivers or pedestrians nearby.

NOTICE

■

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 5°F (-15°C)

or lower, automatic operation may not

occur. In this case, operate the wipers in

any mode other than AUTO mode.

blocked, if there is washer fluid in the

washer fluid tank.

WARNING

■

Caution regarding the use of wind-

shield wipers in AUTO mode (vehi-

cles with rain-sensing windshield

wipers)

The windshield wipers may operate

unexpectedly if the sensor is touched or

the windshield is subject to vibration in

AUTO mode. Take care that your fingers,

etc. do not become caught in the wind-

shield 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 washer fluid tank is empty

Do not operate the switch continually as

the washer fluid pump may overheat.

ensure that all the doors and win-
dows are closed.

 Confirm the type of fuel.

■

Fuel types

P.390

■

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.

With all doors unlocked, press the
center of the rear edge of the fuel
filler door.

Push inward and take your hand away to

slightly open the fuel filler door. Then open

Opening the fuel tank cap

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 of 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 elec-

tricity 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.

NOTICE

■

Refueling

Do not spill fuel during refueling.

Doing so may damage the vehicle, such

as causing the emission control system to

operate abnormally, damaging fuel sys-

tem components or the vehicle’s painted

surface.

When the fuel filler door cannot be

opened

P.371

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

Close the fuel filler door, and press
the center of the rear edge of the
fuel filler door.

When you lock the doors, the fuel filler

door will lock also.

Fuel filler door lock condition

The fuel filler door may not be locked even

when the vehicle’s doors are locked in the

following conditions:

●

When operating the door lock button

inside the vehicle

●

When the automatic door locking system

is operated

●

When the fuel filler door is closed after

the vehicle’s doors are locked

Warning buzzer for loose fuel cap

When the engine switch is IGNITION ON

mode and the cap is loose, the buzzer

sounds and a message is displayed on the

multi-information display.

The pre-collision system is equipped

with a sophisticated computer that will
record certain data, such as:
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the pre-collision

system functions

• Information (such as the distance

and relative speed between your
vehicle and the vehicle ahead or
other objects)

• Images from the camera sensor

(available only when the pre-colli-
sion braking function or the pre-col-
lision brake assist function was
operating)

The pre-collision system does not
record conversations, sounds or
images of the inside of the vehicle.
 Data usage

Lexus may use the data recorded in this
computer to diagnose malfunctions, con-
duct research and development, and
improve quality.
Lexus will not disclose the recorded data to
a third party except:
• With the consent of the vehicle owner or

with the consent of the lessee if the vehi-
cle is leased

• In response to an official request by the

police, a court of law or a government
agency

• For use by Lexus in a lawsuit
• For research purposes where the data is

not tied to a specific vehicle or vehicle
owner

Lexus Safety System+

The Lexus Safety System+ is designed to

operate under the assumption that the

driver will drive safely, and is designed to

help reduce the impact to the occupants

and the vehicle in the case of a collision

or assist the driver in normal driving con-

ditions.

As there is a limit to the degree of recog-

that this system can provide, do not

overly rely on this system. The driver is

always responsible for paying attention
