times, the wipers operate one more time
after a short delay to prevent dripping.
However, this function will not operate while
driving.
■
Effects of vehicle speed on wiper opera-
tion
Vehicle speed affects the intermittent wiper
interval.
■
Raindrop sensor (vehicles with
rain-sensing windshield wipers)
●
The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs, etc. are
present on the windshield
●
If the wiper switch is turned to the
“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” position, the
wipers will operate once to indicate that
the sensor sensitivity is enhanced.
●
If the temperature of the raindrop sensor
is 90°C (194°F) or higher, or -15°C (5°F)
or lower, automatic operation may 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
washer fluid tank.
■
Washer nozzle heaters (if equipped)
The washer nozzle heaters operate when
the outside temperature is 5°C (41°F) or
less and the engine switch is in IGNITION
ON mode.
■
Front door opening linked windshield
wiper stop function (vehicles with
rain-sensing windshield wipers)
When “AUTO” is selected and the wind-
shield wipers are operating, if a front door is
opened, the operation of the windshield
wipers will be stopped to prevent anyone
near the vehicle from being sprayed by
water from the wipers, provided the vehicle
is stopped with the parking brake applied or
the shift lever in P. When the front door is

hold it for approximately 2 seconds or
more.
The wipers will move to the service posi-
tion.
WARNING
■
Caution regarding the use of wind-
shield wipers in AUTO mode (vehi-
cles with rain-sensing windshield
wipers)
The windshield wipers may operate
unexpectedly if the sensor is touched or
the windshield is subject to vibration in
AUTO mode. Take care that your fingers,
etc. do not become caught in the wind-
shield wipers.
■
Caution regarding the use of washer
fluid
When it is cold, do not use the washer
fluid until the windshield becomes warm.
The fluid may freeze on the windshield
and cause low visibility. This may lead to
an accident, resulting in death or serious
injury.
■
When the washer nozzle heaters are
operating (if equipped)
Do not touch the area around the washer
nozzle heaters, as they can become very
hot and burn you.
NOTICE

Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehi-
cle has a fuel tank opening that only accom-
modates the special nozzle on unleaded
fuel pumps.

With the doors unlocked, press the
center of the rear edge of the fuel
filler door.
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 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 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.

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 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

Situation
Actions
When the area around a camera is covered
with dirt, moisture (fogged up, covered with
condensation, ice, etc.), or other foreign
matter
Using the wiper and A/C function, remove
the dirt and other attached matter. (
P.318)
When the temperature around the front
camera is outside of the operational range,
such as when the vehicle is in the sun or in an
extremely cold environment
If the front camera is hot, such as after the
vehicle had been parked in the sun, use the
air conditioning system to decrease the tem-
perature around the front camera.
If a sunshade was used when the vehicle
was parked, depending on its type, the sun-
light reflected from the surface of the sun-
shade may cause the temperature of the
front camera to become excessively high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold envi-
ronment, use the air conditioning system to
increase the temperature around the front
camera.
The area in front of the front camera is
obstructed, such as when the hood is open
or a sticker is attached to the part of the
windshield in front of the front camera.
Close the hood, remove the sticker, etc. to
clear the obstruction.
When “Pre-Collision System Unavailable” is
displayed.
Check whether there is attached materials
on the radar sensor and radar sensor cover,
and if there is, remove it.

*
: If equipped
PCS (Pre-Collision System)
*
The pre-collision system uses a
radar sensor and front camera to
detect objects (
P.223) in front of
the vehicle. When the system
determines that the possibility of a
frontal collision with an object 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 deter-
mines that the possibility of a frontal
collision with an object is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.
The pre-collision system can be disa-
bled/enabled and the warning timing
can be changed. (

of each region may be different. Contact your Lexus dealer for details.
■
Pre-collision warning
When the system determines that the
possibility of a frontal collision is high, a
buzzer will sound and a warning mes-
sage 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
If the system determines that the possi-
bility of a frontal collision is extremely
high, the brakes are automatically
applied to help avoid the collision or
reduce the impact of the collision.
■
Suspension control (if equipped)
When the system determines that the
possibility of a frontal collision is high,
