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 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
■
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 sur-
face.

Lexus Safety System+
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.

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

◆
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.
◆
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. 379) will control the damping
force of the shock absorbers to help maintain an appropriate vehicle posture.
PCS (Pre-Collision System)
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. (

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.
■
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.
