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

●

Finish refueling within 30 minutes. If more than 30 minutes passes, the internal valve

closes. In this condition, fuel may overflow during the refueling process. Press the fuel

filler door opener switch again.

●

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.

●

If the fuel filler door cannot be opened by

pressing the rear edge of the fuel filler door

with the doors unlocked, remove the cover

inside the luggage compartment and pull the

lever to open the fuel filler door.

●

Using the lever to open the fuel filler door may

not allow for an adequate reduction in fuel

tank pressure before refueling. To prevent fuel

from spilling out, turn the cap slowly when

removing it.

During refueling, fuel may spill out from the

filler opening due to air being discharged from

inside the fuel tank. Therefore, fill the fuel tank

carefully and slowly.

If the fuel filler door cannot be opened by press-

ing its rear edge with the doors unlocked,

remove the cover inside the luggage compart-

ment using a tool, such as a flathead screw-

driver, and pull the lever to open the fuel filler

door.

When using a screwdriver, make sure to wrap its

tip with tape to protect the cover.

NOTICE

■

When refueling
When refueling your vehicle, make sure that

the fuel filler door lock is not pushed by the fuel

nozzle boot, etc., as this may cause a valve to

close, possibly resulting in a fuel spill.
If the fuel filler door lock has been pushed,

operate the fuel filler door opener switch in the

vehicle before continuing to refuel.

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.

280

4-5. Using the driving support systems

RX450h_RX450hL_U

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.

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. (

P. 290)

◆

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. 383) will control the damp-

ing force of the shock absorbers to help maintain an appropriate vehicle pos-
ture.
