NOTICE
Camera sensor (P. 274)
Observe the following to ensure that the LKA 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.
When adjusting the rear view mirror, make sure that it does not block the
camera lens.
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 place anything on the dashboard.
The camera sensor may recognize the image reflected on the windshield
as lane markers by mistake.
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 qualified 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 dis-
assemble the camera sensor.
Do not attach a sticker or other items to
the windshield near the camera sensor.
Do not install or place anything near the
camera.

CAUTION
Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The Blind Spot Monitor is a supplementary system which alerts the driver
that a vehicle is present in the blind spot. Do not overly rely on the Blind
Spot Monitor system. The system cannot judge if it is safe to change lanes,
therefore over reliance could cause an accident resulting in death or serious
injury. According to conditions, the system may not function correctly.
Therefore the driver’s own visual confirmation of safety is necessary.
Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of
the vehicle rear bumper respectively. Observe the following to ensure the
Blind Spot Monitor system can function correctly.
Do not subject the sensor or surrounding area on the bumper to a strong
impact. If the sensor moves even slightly off position, the system may
malfunction and vehicles that enter the detection area may not be
detected. If the sensor or surrounding area is subject to a strong impact,
always have the area inspected by any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional.
Do not disassemble the sensor.
Do not attach accessories or stickers to the sensor or surrounding area on
the bumper.
Do not modify the sensor or surrounding area on the bumper.
Do not paint the sensor or surrounding area on the bumper.
Keep the sensor and its surrounding
area on the bumper clean at all times.
