●In the following situations, if the situation has changed (or the vehicle has been driven for
some time) and the normal operating conditio ns 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 front of the vehicle, such as when driving
in the dark, snow, or fog, or when brig ht lights are shining into the front camera
When the temperature around the front
camera is outside of th e 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
■Before using LDA system
●Do not rely solely upon the LDA sys-
tem. The LDA system does not auto-
matically drive the vehicle or reduce
the amount of attention that must be
paid to the area in front of the vehicle.
The driver must always assume full
responsibility for driving safely by pay-
ing careful attention to the surround-
ing conditions and operating the
steering wheel to correct the path of
the vehicle. Also, the driver must take
adequate breaks when fatigued, such
as from driving for a long period of
time.
●Failure to perform appropriate driving
operations and pay careful attention
may lead to an accident, resulting in
death or serious injury.
●When not using the LDA system, use
the LDA switch to turn the system off.
■Situations unsuitable for LDA system
In the following situations, use the LDA
switch to turn the system off. Failure to do
so may lead to an acc ident, resulting in
death or serious injury.
●Vehicle is driven on a road surface
which is slippery due to rainy weather,
fallen snow, freezing, etc.
●Vehicle is driven on a snow-covered
road.
●White (yellow) lines are difficult to see
due to rain, snow, fog, dust, etc.
●A spare tire, tire chains, etc. are
equipped.
●When the tires have been excessively
worn, or when the tire inflation pres-
sure is low.
●When tires of a size other than speci-
fied are installed.
●Vehicle is driven in traffic lanes other
than that highways and freeways.
●When your vehicle is towing a trailer
or during emergency towing.
■Preventing LDA system malfunctions
and operations performed by mistake
●Do not modify the headlights or place
stickers, etc. on the surface of the
lights.
●Do not modify the su spension, etc. If
the suspension, etc. needs to be
replaced, contact your Lexus dealer.

hood or grille. Also, do not install a
grille guard (bull bars, kangaroo bar,
etc.).
●If your windshield needs repairs, con-
tact your Lexus dealer.
■Conditions in which functions may
not operate properly
In the following situations, the functions

• When the vehicle is driven on a metal cover (grating), such as those used for
drainage ditches
• The vehicle is driven on a steep slope
• The sensor is covered by water on a flooded road
●Influence from the weather
• Ice, snow, dirt, etc., has adhered to the
sensor (if removed, the system returns to
normal)

types), fog lights, a fe nder pole or a wire-
less antenna) are installed near the sen-
sors
●Changes in the vehicle

●If the windows are very dirty, do not open
and close them repeatedly.
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehi-
cle, such as on the floor, in the hybrid
battery (traction battery) air vents, and
in the luggage compartment. Doing so
may cause the hybrid battery, electri-
cal components, etc. to malfunction or
catch fire.
●Do not get any of the SRS components
or wiring in the vehicle interior wet.
( P.32)
An electrical malfunction may cause
the airbags to deploy or not function
properly, resulting in death or serious
injury.
■Cleaning the interior (especially
instrument panel)
Do not use polish wax or polish cleaner.
The instrument panel may reflect off the
windshield, obstructing the driver’s view
and leading to an accident, resulting in
death or serious injury.
NOTICE
■Cleaning detergents
●Do not use the following types of
detergent, as they may discolor the
vehicle interior or cause streaks or
damage to painted surfaces:
• Non-seat portions: Organic sub- stances such as benzene or gasoline,
alkaline or acidic solutions, dye, and
bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alcohol
●Do not use polish wax or polish
cleaner. The instrument panel’s or
other interior part’s painted surface
may be damaged.
■Preventing damage to leather sur-
faces
Observe the following precautions to
avoid damage to and deterioration of
leather surfaces:
●Remove any dust or dirt from leather
surfaces immediately.
●Do not expose the vehicle to direct
sunlight for extended periods of time.
Park the vehicle in the shade, espe-
cially during summer.
●Do not place items made of vinyl, plas-
tic, or containing wax on the uphol-
stery, as they may stick to the leather
surface if the vehicle interior heats up
significantly.
■Water on the floor
Do not wash the vehicle floor with
water.Vehicle systems such as the audio
system may be damaged if water comes
into contact with electrical components
such as the audio system above or under
the floor of the vehicle. Water may also
cause the body to rust.
■When cleaning the inside of the wind-
shield (vehicles with Lexus Safety
System + 2.0)
Do not allow glass cleaner to contact the
lens. Also, do not touch the lens.
(  P.205)
■Cleaning the inside of the rear win-
dow
●Do not use glass cleaner to clean the
rear window, as this may cause dam-
age to the rear window defogger
heater wires or antenna. Use a cloth
dampened with lukewarm water to
gently wipe the window clean. Wipe
the window in strokes running parallel
to the heater wires or antenna.
●Be careful not to scratch or damage
the heater wires or antenna.
