●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 du e 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 syst em malfunction or to inform the driver of
the need for caution while driving. ( P. 555)
WA R N I N G
■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 drivin g 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, dirt, 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.
If any suspension parts need to be replaced, contact your Lexus dealer.
●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 your Lexus dealer.
■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 windshie ld 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 area of the windshield in front of the camera sensor is fogged up, use the wind-
shield defogger to remove the fog.
When it is cold, setting the heater to blow air to the feet only may cause the area of
the windshield in front of the camera sensor 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 your Lexus dealer.
●Do not change the installation position or di rection of the camera sensor or remove it.
The direction of the camera se nsor is precisely adjusted.
●Do not subject the camera sensor to strong impact or force, and do not disassemble
the camera sensor.
●If the windshield needs to be re placed, contact your Lexus dealer.
●Do not attach a sticker or other items to the
windshield near the camera sensor.

■Conditions that may trigger the system even if there is no danger of a collision
In any of the following situations where the frontal area of the radar sensor is inter-
rupted, the radar sensor may detect possibility of a frontal collision and the system
may be activated.
●When passing by an oncoming vehicle in a curve or a turn to the right or the left
●When rapidly approaching an obstacle ahead (e.g. preceding vehicle, toll gate barrier,
etc.)
●When there is a structural ob ject (billboard, low ceiling, fluorescent light, etc.) above
the uphill road ahead
●When driving on a narrow road or through under a low overhead structure (bridge,
tunnel, fly-under, etc.)
●When driving on an uneven road surface
●When there is a metal object, bump, or protrusion on the road surface
●When vehicle’s front part is raised or lowered depending on loading conditions
●When the direction of radar sensor is misa ligned by strong impact applied on an area
around the radar sensor, etc.
●When there is an obstacle (guard rail, etc.) by the roadside at the entrance to a curve
●When the front of your vehicle is pointing upwards (caused by putting a heavy load in
the trunk etc.)
When the system is activated in the situations described above, there is also a possibility
that the brakes may be applied with a force greater than normal.
■Obstacles not detected
The sensor cannot detect plasti c 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-collision 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 your vehicle is steeply inclined
●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
●When an obstacle suddenly appears in front of the vehicle due to the steering wheel
being turned sharply or another cause
■Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor cont amination, etc. that results in the sensors
being unable to detect obstacles, the pre-collision syst em will be automatically disabled.
In this case, the system will not activate even if there is a collision possibility.

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 substances such as benzene or gasoline, alkaline oracidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, su ch 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 surfaces
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, especially during summer.
●Do not place items made of vinyl, plastic, or containing wax on the upholstery, as they
may stick to the leather su rface 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 au dio 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 5 3 ) .
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 cl ean. 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.
