Effects of vehicle speed on wiper opera-

tion (vehicles with rain-sensing wind-

shield wipers)

Vehicle speed affects the Intermittent wiper

interval.

Raindrop sensor (vehicles with rain-

sensing windshield wipers)

The raindrop sensor judges the amount

of raindrops.

An optical sensor is adopted. It may not

operate 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 the wiper switch is turned to the

“AUTO” position while the power switch

is in ON, the wipers will operate once to

show that AUTO mode is activated.

If the temperature of the raindrop sensor

is 90°C (194°F) or higher, or -15°C

(5°F) or lower, automatic operation may

not occur. In this case, operate the wipers

in any mode other than AUTO mode.

If no windshield washer fluid sprays

Check that the washer nozzles are not

blocked, if there is washer fluid in the

washer fluid tank.

214

4-3. Operating the lights and wipers

When the windshield wipers are not
being used, they retract to below the
hood. To enable the windshield wipers
to be lifted when parking in cold condi-

tions or when replacing a windshield
wiper insert, change the rest position of
the windshield wipers to the service
position using the wiper lever.

Raising the wipers to the service
position

Within approximately 45 seconds of
turning the power switch off, move the
wiper lever to the

position and

hold it for approximately 2 seconds or
more.

The wipers will move to the service posi-
tion.

Lifting the windshield wipers

While holding the hook portion

the wiper arm, lift the windshield wiper
from the windshield.

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 fin-

gers, etc. do 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 washer fluid tank is empty

Do not operate the switch continually as

the washer fluid pump may overheat.

When a nozzle becomes blocked

In this case, contact any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer.

Do not try to clear it with a pin or other

object. The nozzle will be damaged.

To prevent 12-volt battery discharge

Do not leave the wipers on longer than

necessary when the hybrid system is off.

P.474

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

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.

NOTICE

Refueling

Do not spill fuel during refueling.

Doing so may damage the vehicle, such

as causing the emission control system to

operate abnormally or damaging fuel

system components or the vehicle’s

painted surface.

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.

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 inci-

4-5. Using the driving support systems

In the following situations, if the situation has changed (or the vehicle has been driven for

some time) and the normal operating conditions are detected, the message will disap-

pear and the system will become operational.

If the message does not disappear, contact any authorized Lexus retailer or Lexus autho-
rized repairer, or any reliable repairer.
• When the temperature around the radar sensor is outside of the operational range, such

as when the vehicle is in the sun or in an extremely cold environment

• When the front camera cannot detect objects in front of the vehicle, such as when driving

in the dark, snow, or fog, or when bright lights are shining into the front camera

• Depending on the conditions in the vicinity of the vehicle, the radar may judge the sur-

rounding environment can not be properly recognized. In that case, “Pre-Collision Sys-

tem Unavailable” is displayed.

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.327)

When the temperature around the front
camera is outside of the operational range,
such as when the vehicle is in the sun or in an
extremely cold environment

If the front camera is hot, such as after the
vehicle had been parked in the sun, use the
air conditioning system to decrease the tem-
perature 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 envi-
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 Unavailable” is
displayed.

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

The countries and areas for each region listed in the table are current as of August
2021. However, depending on when the vehicle was sold, the countries and areas
of each region may be different. Contact your Lexus dealer for details.

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.

PCS (Pre-Collision System)

The pre-collision system uses a radar sensor and front camera to detect
objects (



P.231) in front of the vehicle. When the system determines that the

possibility of a frontal collision with an object 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 an object 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. (
