●When sunlight or the headlights of oncoming vehicles are shining directly into the cam-
era lens
●When driving on roads that are branching or merging
●When driving on a road surface that is wet due to rain, previous rainfall, standing water,
etc.
●When the vehicle experiences strong up-and-down motion such as when driving on an
extremely rough road or on a seam in the pavement
●When headlight brightness at nighttime is reduced due to dirt on the lenses, or when
the headlights are misaligned
●When driving on winding roads or roads that are uneven
●When driving on rough or unpaved roads
■When changing the tires
Depending on the tires used, sufficient performance may not be maintainable.
■Warning messages for the LDA system
Warning messages are used to indicate a system malfunction or to inform the driver of
the need for caution while driving. (→P. 4 8 6 )
CAUTION
■Before using the LDA system
Do not rely solely on the LDA system. The LDA system does not drive the vehicle auto-
matically, nor does it reduce the amount of care you need to take. As such, the driver
must always assume full responsibility for understanding his/her surroundings, for
operating the steering wheel to correct the driving line, and for driving safely.
Inappropriate or negligent driving could lead to an accident.
■To avoid operating the LDA by mistake
Switch the LDA system off using the LDA switch when not in use.
■Situations unsuitable for LDA system
Do not use the LDA system in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident.
●When driving with tire chains, a spare tire, or similar equipment
●When there are objects or structures along the roadside that might be misinterpreted
as lane markers (such as guardrails, a curb, reflector posts, etc.)
●When driving on snowy roads
●When pavement lane markers are difficult to see due to rain, snow, fog, sand dust etc.
●When there are visible lines on the pavement from road repairs, or if the remains of
old lane markers are still visible on the road
●When driving on a road with lane closures due to maintenance, or when driving in a
temporary lane

NOTICE
■To prevent damage to or incorrect operation of the LDA system
●Do not modify the headlights or attach stickers to the surface of the lights.
●Do not modify the suspension or replace it with non-genuine parts.
●Do not install or place anything on the hood or the grille. Also, do not install a grille
guard (bull bars, kangaroo bar etc.).
●If your windshield needs repairs, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
■Camera sensor
Observe the following to ensure that the LDA system functions correctly.
●Keep the windshield clean at all times.
Performance could be affected if the windshield is dirty, or if raindrops, condensation
or ice are adhering to the windshield.
●Do not spill liquid onto the camera sensor.
●Do not attach window tinting to the windshield.
●Do not install an antenna in front of the camera lens.
●If the windshield is fogged up, use the windshield defogger to remove fog from the
windshield.
When it is cold, using the heater with air blowing to the feet may allow the upper part
of the windshield to fog up. This will have a negative effect on the images.
●Do not scratch the camera lens, or let it get dirty.
When cleaning the inside of the windshield, be careful not to get any glass cleaner
etc. on the lens. Also, do not touch the lens.
For lens repair, contact any authorized Lexus dealer or repairer, or another duly qual-
ified and equipped professional.
●Do not change the installation position or direction of the camera sensor or remove it.
The direction of the camera sensor is precisely adjusted.
●Do not subject the camera sensor to strong impact or force, and do not disassemble
the camera sensor.
●Do not replace windshield with non-genuine windshield.
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
●Do not attach a sticker or other items to the
windshield near the camera sensor.

■Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also be occa-
sions when the sensor cannot detect pedestrians, animals, bicycles, motorcycles, trees,
or snowdrifts.
■Situations in which the pre-crash safety system does not function properly
The system may not function effectively in situations such as the following:
●On roads with sharp bends or uneven surfaces
●If a vehicle suddenly moves in front of your vehicle, such as at an intersection
●If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
●In inclement weather such as heavy rain, fog, snow or sand storms
●If the vehicle is skidding when VSC is not operating
●When an extreme change in vehicle height occurs
●When only part of your vehicle’s front end collides with, or contacts, a vehicle or object
in a frontal collision
●When the radar sensor moves off position due to its surrounding area being subjected
to a strong impact
■Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in the sensors
being unable to detect obstacles, the pre-crash safety system will be automatically dis-
abled. In this case, the system will not activate even if there is a collision possibility.
■When there is a malfunction in the system
The pre-crash safety system warning light will flash and warning messages will be dis-
played. (→P. 477, 487)

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 windshield (vehicles with LDA [Lane Departure
Alert])
Be careful not to touch the camera sensor (→P. 2 4 1 ) .
If the camera is accidentally scratched or hit, LDA may not operate properly or may
cause a malfunction.
■Cleaning the inside of the rear window
●Do not use glass cleaner to clean the rear window, as this may cause damage to the
rear window defogger heater wires or antenna. Use a cloth dampened with luke-
warm water to gently wipe the window clean. Wipe the window in strokes running
parallel to the heater wires or antenna.
