When refueling the vehicle
Observe the following precautions while refu eling the vehicle. Failure to do so may
result in death or serious injury. ●
After exiting the vehicle and before openin g 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 fr om static electricity can cause fuel vapors
to ignite while refueling. ●
Always hold the grips on th e 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 th at 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.

: If equippedThe Lexus Safety System+ consists of the following drive assist systems and
contributes to a safe and comfo rtable driving experience:

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 vehicl e's surroundings and driving safely.

RX350_U_OM48E90U The pre-collision system is equipped wi th 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)
Additionally, if the pre-collision braking fu nction is operating, image information
from the camera sensor will also be re corded. The pre-collisio n system does not
record conversations, sounds or pictures. ●
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 image information can be erased using a specialized device.
The image information recording function can be disabled. However, if the
function is disabled, data from when the pre-collision system operates will not
be available.Vehicle data recording
