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 the following situations, the front of the sensor may be obstructed causing the system
to determine that there is a poss ibility of a collision and operate:
●When passing an oncoming vehicle on a cu rb or while making a left or right turn
●When rapidly closing on an obstruction in front of the vehicle, such as a vehicle or toll
gate
●When climbing a hill, and an overhead structure (billboard, low ceiling, street lamps,
etc.) appears in the vehicle’s line of travel
●When driving through a narrow passage or a place with a low ceiling (bridges, tunnels,
overhead passes, etc.)
●When driving on an uneven road surface
●When there is a metal object on the road surf ace, or a gap or protrusion in the road sur-
face
●When there is an extreme change in the vehicle height
●When the sensor is misaligned due to a stro ng impact to the surrounding area of the
sensor
●When there is an object on the side of the road at the entrance to a curve, such as
guardrails
●When the front of your vehicle is inclined (during emergency towing, carrying 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 will 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 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.
■When there is a malfunction in the system or if the system is temporarily unusable
The pre-collision system warning light will flash or illuminate and warning messages will
be displayed. ( P. 5 3 4 , 5 4 5 )

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 4 8 ) .
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.
