Raindrop sensor

●

If the wiper switch is turned to the “AUTO” position while the engine switch is in

IGNITION ON mode, the wipers will operate once to show that “AUTO” mode is acti-

vated.

●

When the sensor sensitivity ring is turned toward high while in “AUTO” mode, the wip-

ers will operate once to indicate that the sensor sensitivity is enhanced.

●

If the temperature of the rain drop sensor is 185

F (85C) or higher, or -22F (-30C)

or lower, the automatic operation may not occur. In this case, operate the wipers in any

mode other than “AUTO”.

●

The raindrop sensor judges the amount of

raindrops.
An optical sensor is adopted. It may not oper-

ate properly when sunlight from the rising or

setting of the sun intermittently strikes the

windshield, or if bugs etc. are present on the

windshield.

■

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

Turn the engine switch off and ensure that all the doors and windows are
closed.

●

Confirm the type of fuel.

Fuel types
P. 570

■

Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Lexus has a fuel tank opening that only accommo-

dates the special nozzle on unleaded fuel pumps.

Perform the following steps to open 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 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 bodies 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.

246

4-4. Refueling

Pull the lever.

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

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
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.

WARNING

■

When replacing the fuel tank cap
Do not use anything but a genuine Lexus fuel tank cap designed for your vehicle. Doing

so may cause a fire or other incident which may result in death or serious injury.

The Lexus Safety System + consists of the following drive assist systems and
contributes to a safe and comfortable driving experience:

WARNING

■

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 conditions.
As there is a limit to the degree of recognition accuracy and control performance that

this system can provide, do not overly rely on this system. The driver is always responsi-

ble for paying attention to the vehicle’s surroundings and driving safely.

249

4-5. Using the driving support systems

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-collision braking

function or the pre-collision 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,
conduct 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 vehicle is leased

• In response to an official request by the police, a court of law or a govern-

ment agency

• For use by Lexus in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or

vehicle owner

●

Recorded images can be erased using a specialized device.
The image recording function can be disabled. However, if the function is dis-
abled, data from when the pre-collision system operates will not be available.

WARNING

■

To avoid malfunction of the radar sensor
Observe the following precautions.
Otherwise, the radar sensor may not operate properly, possibly leading to an accident

resulting in death or serious injury.

●

Keep the radar sensor and front grille emblem clean at all times.

●

Do not attach accessories, stickers (including transparent stickers) or other items to

the radar sensor, front grille emblem or surrounding area.

●

Do not subject the radar sensor or surrounding area to a strong impact. 

If the radar sensor, front grille, or front bumper has been subjected to a strong impact,

have the vehicle inspected by your Lexus dealer.

●

Do not disassemble the radar sensor.

●

Do not modify or paint the radar sensor, front grille emblem or surrounding area.

●

If the radar sensor, front grille, or front bumper needs to be removed and installed, or

replaced, contact your Lexus dealer.

Radar sensor
Front grille emblem

If the front of the radar sensor or the front or

back of the front grille emblem is dirty or

covered with water droplets, snow, etc., clean

it.
Clean the radar sensor and front grille

emblem with a soft cloth so you do not mark

or damage them.
