●House lights, street lights, traffic signals,
and illuminated billboards or signs and
other reflective objects may cause the
high beams to change to the low beams,
or the low beams to remain on.
●The following factors may affect the
amount of time taken for the high beams
to turn on or off:
• The brightness of the headlights, fog
lights, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has opera- tional lights on one side
• When a vehicle ahead is a two-wheeled
vehicle
• The condition of the road (gradient, curve, condition of th e road surface, etc.)
• The number of passengers and amount of luggage in the vehicle
●The high beams may turn on or off unex-
pectedly.
●Bicycles or similar vehicles may not be
detected.
●In the following situations the system may
not be able to correctly detect the sur-
rounding brightness le vel. This may cause
the low beams to remain on or the high
beams to flash or dazzle pedestrians or
vehicles ahead. In such a case, it is neces-
sary to manually switch between the high
and low beams.
• When driving in inclement weather
(heavy rain, snow, fog, sandstorms, etc.)
• When the windshield is obscured by fog, mist, ice, dirt, etc.
• When the windshield is cracked or dam- aged
• When the front camera is deformed or
dirty
• When the temperature of the front cam- era is extremely high
• When the surrounding brightness level is equal to that of head lights, tail lights or
fog lights
• When headlights or tail lights of vehicles
ahead are turned off, dirty, changing
color, or not aimed properly
• When the vehicle is hit by water, snow,
dust, etc. from a preceding vehicle
• When driving through an area of inter-mittently changing brightness and dark-
ness
• When frequently and repeatedly driving
ascending/descending roads, or roads
with rough, bumpy or uneven surfaces
(such as stone-paved roads, gravel roads,
etc.)
• When frequently and repeatedly taking curves or driving on a winding road
• When there is a highly reflective object ahead of the vehicle, such as a sign or
mirror
• When the back of a preceding vehicle is highly reflective, such as a container on a
truck
• When the vehicle’s headlights are dam- aged or dirty, or are not aimed properly
• When the vehicle is listing or titling due to
a flat tire, a trailer being towed, etc.
• When the headlights are changed between the high beams and low beams
repeatedly in an abnormal manner
• When the driver believes that the high beams may be flashing or dazzling
pedestrians or other drivers
■Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be tempo-
rarily lowered.
1 Turn the engine switch off while the fol-
lowing conditions are met.
●The headlight switch is in or

■The windshield wipers and washer can
be operated when
The engine switch is in ON.
■Effects of vehicle speed on wiper opera-
tion (vehicles with rain-sensing wind-
shield wipers)
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 ON,
the wipers will operate once to show that
AUTO mode is activated.
●If the temperature of the raindrop sensor
is 194°F (90°C) or higher, or 5°F (-15°C)
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.
When the windshield wipers are not
being used, they retract to below the
hood. To enable the windshield wipers
to be lifted when parking in cold condi-
tions or when replacing a windshield
wiper insert, change the rest position of
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.
NOTICE
■When the washer fluid tank is empty
Do not operate the switch continually as
the washer fluid pump may overheat.
■When a nozzle becomes blocked
In this case, contact your Lexus dealer.
Do not try to clear it with a pin or other
object. The nozzle will be damaged.

●In the following situations, if the situation has changed (or the vehicle has been driven for
some time) and the normal operating conditions are detected, the message will disappear
and the system will become operational.
If the message does not disappea r, contact your Lexus dealer.
When the temperature around the radar sensor is outside of the operational range, such as
when the vehicle is in the sun or in an extremely cold environment
When the front camera cannot detect objects in fr ont of the vehicle, such as when driving in
the dark, snow, or fog, or when bright lights are shining into the front camera
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 sunlight
reflected from the surface of the sunshade
may cause the temperature of the front cam-
era 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.

WARNING
●Although this system is designed to
help avoid a collision or help reduce
the impact of the collision, its effective-
ness may change according to various
conditions, therefore the system may
not always be able to achieve the same
level of performance. Read the follow-
ing conditions carefully. Do not overly
rely on this system and always drive
carefully.
• Conditions under which the system may operate even if there is no possi-
bility of a collision: P.190
• Conditions under which the system may not operate properly: P.191
●Do not attempt to test the operation of
the pre-collision system yourself.
Depending on the objects used for
testing (dummies, cardboard objects
imitating detectable objects, etc.), the
system may not operate properly, pos-
sibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking func-
tion is operating, a large amount of
braking force will be applied.
●If the vehicle is stopped by the opera-
tion of the pre-collision braking func-
tion, the pre-collision braking function
operation will be canceled after
approximately 2 seco nds. Depress the
brake pedal as necessary.
●The pre-collision braking function may
not operate if certain operations are
performed by the driver. If the acceler-
ator pedal is being depressed strongly
or the steering wheel is being turned,
the system may determine that the
driver is taking evasive action and pos-
sibly prevent the pre-collision braking
function from operating.
●In some situations, while the pre-colli-
sion braking function is operating,
operation of the function may be can-
celed if the accelerator pedal is
depressed strongly or the steering
wheel is turned and the system deter-
mines that the driver is taking evasive
action.
●If the brake pedal is being depressed,
the system may determine that the
driver is taking evasive action and pos-
sibly delay the operat ion timing of the
pre-collision braking function.
■When to disable the pre-collision sys-
tem
In the following situations, disable the
system, as it may not operate properly,
possibly leading to an accident resulting
in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another
vehicle
●When transporting the vehicle via
truck, boat, train or similar means of
transportation
●When the vehicle is raised on a lift with
the engine running and the tires are
allowed to rotate freely
●When inspecting the vehicle using a
drum tester such as a chassis dyna-
mometer or speedometer tester, or
when using an on vehicle wheel bal-
ancer
●When a strong impact is applied to the
front bumper or front grille, due to an
accident or other reasons
●If the vehicle cannot be driven in a sta-
ble manner, such as when the vehicle
has been in an accident or is malfunc-
tioning
●When the vehicle is driven in a sporty
manner or off-road
●When the tires are not properly
inflated
