4-3. Operating the lights and wipers
The wipers can be used as intermittent windshield wipers, which operate regard-
less of vehicle speed or amount of raindrops. The intermittent windshield wiper
operation can be switched when the vehicle is stopped and the wiper is off. The
wiper operation cannot be switched during AUTO mode or while the intermit-
tent windshield wipers are operating.
Press and hold
until the AUTO
mode indicator stops flashing.
If
is pressed and held until the
AUTO mode indicator stops flashing
again, it will return to its previous state.
■
The windshield wiper and washer can be operated when
The engine switch is in IGNITION ON mode.
■
Dripping prevention wiper sweep
After washing and wiping operation several times, the wipers operate one more time
after a short delay to prevent dripping.
However, the last sweep will not happen while the vehicle is moving.
■
Effects of vehicle speed on wiper operation
●
Intermittent windshield wipers interval changes when the vehicle is stopped.
●
With low speed operation selected, wiper operation will be switched from low speed to
intermittent operation only when the vehicle is stationary.
■
Raindrop sensor
●
If AUTO mode is selected while the engine switch is in IGNITION ON mode, the wip-
ers will operate once to show that AUTO mode is activated.
●
If the temperature of the raindrop sensor is 185°F (85°C) or higher, or -22°F
(-30°C) or lower, automatic operation may not occur. In this case, operate the
wipers in any mode other than AUTO mode.
Switching between the intermittent windshield wipers and rain-sensing
windshield wipers (vehicles with rain-sensing windshield wipers)
●
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.

■
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 the filler neck and cause injury.
●
Do not allow anyone that has not discharged 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 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.
NOTICE
■

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

PCS (Pre-Collision System)
◆
Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a warn-
ing message 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.
: If equipped
The pre-collision system uses a radar sensor and camera sensor to detect
vehicles and pedestrians in front of your vehicle. When the system 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 possibility of a frontal collision with a vehicle or pedes-
trian 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. (

◆
Pre-collision braking
When the system determines that the possibility of a frontal collision is high,
the system warns the driver. If the system 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 (if equipped)
When the system determines that the possibility of a frontal collision is high,
the Adaptive Variable Suspension System (
P. 297) will control the damping
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 (
control the turning angle of the front and rear wheels and effort necessary to
turn the steering wheel to help enhance steering responsiveness.
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 collision damage or
injury in every situation. Do not overly rely on this system. Failure to do so may lead to
an accident, 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 effectiveness 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 carefully. Do not overly rely on this system and always
drive carefully.
• Conditions under which the system may operate even if there is no possibility of a
collision:
• Conditions under which the system may not operate properly:
●
Do not attempt to test the operation of the pre-collision system yourself, as the system
may not operate properly, possibly leading to an accident.

WARNING
■
Pre-collision braking
●
When the pre-collision braking function is operating, a large amount of braking force
will be applied.
●
If the vehicle is stopped by the operation of the pre-collision braking function, 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 per-
formed by the driver. If the accelerator pedal is being depressed strongly or the steer-
ing wheel is being turned, the system may determine that the driver is taking evasive
action and possibly prevent the pre-collision braking function from operating.
●
In some situations, while the pre-collision braking function 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.
●
If the brake pedal is being depressed, the system may determine that the driver is tak-
ing evasive action and possibly delay the operation timing of the pre-collision braking
function.
■
When to disable the pre-collision system
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 and the tires are allowed to
rotate freely
●
When inspecting the vehicle using a drum tester such as a chassis dynamometer or
speedometer tester, or when using an on vehicle wheel balancer
●
When a strong impact is applied to the front bumper or front grille, due to an accident
or other reasons
●
If the vehicle cannot be driven in a stable manner, such as when the vehicle has been
in an accident or is malfunctioning
●
When the vehicle is driven in a sporty manner or off-road
●
When the tires are not properly inflated
●
When the tires are very worn
●
When tires of a size other than specified are installed
