To help prevent incorrect fueling, your vehi-
cle has a fuel tank opening that only accom-
modates the special nozzle on unleaded
fuel pumps.Opening the fuel tank cap Perform the following steps to open
the fuel tank cap:
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 ve hicle 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.
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 surface.

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 in situations when
sudden inputs occur while driving
[sudden acceleration, etc.], the
pre-collision braking function or the
pre-collision brake assist function
was operating, the Parking Support
Brake function [static objects] was
operating, or your vehicle was

Drive assist systems of Lexus
Safety System+A WARNING■
Lexus Safety System+A
The Lexus Safety System+A 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 con-
ditions.
As there is a limit to the degree of recog-
nition accuracy and control performance
that this system can provide, do not
overly rely on this system. The driver is
always responsible for paying attention
to the vehicle’s surroundings and driving
safely.
Vehicle data recording

188 4-5. Using the driving support systems
LS500_OM_OM50F54U_(U) 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, con-
duct 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 vehi-
cle is leased
• In response to an of ficial request by the
police, a court of law or a government
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 dis-
abled. However, if the function is disabled,
data from when the pre-collision system
operates will not be available.
Four types of sensors, located behind
the front grille, front bumper, rear
bumper and windshield, detect infor-
mation necessary to operate the drive
assist systems.
