4-3. Operating the lights and wipers

Driving

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 engine switch <power
switch> off, move the wiper lever to the

position and hold it for approxi-

mately 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

gers or anything else 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 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.

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.

192

4-4. Refueling

Press the opener.

LC500h: The fuel filler door will open

within about 10 seconds of the switch

being pressed. Before refueling is possible,

a message will be shown on the multi-infor-

mation display in the instrument cluster to

indicate the progress of the fuel filler door

opener.

Open the fuel filler door until it is
securely locked.

The fuel filler door will be locked when it is

opened until it becomes perpendicular to

the base.

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

●

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 disappear

and the system will become operational.

If the message does not disappear, contact your Lexus dealer.

• 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

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.

4-5. Using the driving support systems

■

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

When the system determines that the
possibility of a frontal collision is high,
the system warns the driver. If the sys-
tem 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

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



P.243) will control the damp-

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

■

Steering control (if equipped)

When the system determines that the
possibility of a frontal collision is high
and the driver is operating the steering
wheel, the LDH system (



P.244) will

control the turning angle of the front

PCS (Pre-Collision System)

The pre-collision system uses a
radar sensor and front camera to
detect vehicles and pedestrians in
front of your vehicle. When the sys-
tem 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 possi-
bility of a frontal collision with a
vehicle or pedestrian is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.

The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. (

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.203

• Conditions under which the system

may not operate properly:



P.205

●

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.

■

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 engine running <hybrid system on>

and the tires are allowed to rotate

freely

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 12-volt battery terminal has been dis-

connected and reconnected and then the

vehicle has not been driven for a certain

amount of time

●

If the shift position is in R

●

If VSC is disabled (only the pre-collision

warning function will be operational)

■

Pedestrian detection function

The pre-collision system detects pedestri-

ans based on the size, profile, and motion of

a detected object. However, a pedestrian

may not be detected depending on the sur-

rounding brightness and the motion, pos-

ture, and angle of the detected object,

preventing the system from operating prop-

erly. (
