Driving
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to AUTO position while the engine switch is in IGNITION
ON mode, the wipers will operate once to show that AUTO mode is activated.
●When the sensor sensitivity ring is turned toward high while in AUTO mode, the wipers
will operate once to indicate that the sensor sensitivity is enhanced.
●If the temperature of the raindrop sensor is 185°F (85°C) or higher, or -22°F
(-30°C) or lower, automatic operation ma y not occur. In this case, operate the
wipers in any mode other than AUTO mode.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the windshield
washer fluid reservoir.
●The raindrop sensor judges the amount of
raindrops.
An optical sensor is ad opted. 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.

■Caution regarding the use of windshield wi pers in AUTO mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield is subject to vibration in AUTO mode. Take care that your fingers or anything
else do not become caught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fl uid until the windshield becomes warm. The
fluid may freeze on the windshield and cause lo w visibility. This may lead to an accident,
resulting in death or serious injury.

Driving
Opening the fuel tank cap
●Turn the engine switch off and ensure that all the doors and windows are
closed.
●Confirm the type of fuel.
■Fuel types

P. 5 2 1
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that only accom-
modates the special nozzle on unleaded fuel pumps.
Perform the following steps to open the fuel tank cap:
Before refueling the vehicle
WA R N I N G
■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 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.

ES350_OM_OM33B64U_(U)4-4. Refueling
Press the opener switch to open the
fuel filler door.
Turn the fuel tank cap slowly to open
and hang it on the back of the fuel
filler door.
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.

The Lexus Safety System+ consists of the following drive assist systems and
contributes to a safe and comfo rtable driving experience:
WA R N I N G
■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.

Driving
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)
Additionally, if the pre-collision braking fu nction is operating, image information
from the camera sensor will also be recorded. 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.
