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.

Buzzer operation and distance to an obstacle
A buzzer sounds when the corner sensors and rear center sensors
are operating.
The buzzer beeps faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the
obstacle, the buzzer sounds continuously:
• Front center sensors: Approximately 30 cm (1.0 ft.)
• Corner sensors: Approximately 30 cm (1.0 ft.)
• Rear center sensors: Approximately 35 cm (1.1 ft.)
When 2 or more obstacles are detected simultaneously, the
buzzer system responds to the nearest obstacle. If one or both
come within the above distances, the beep will repeat a long
tone, followed by fast beeps.
Approximately 100 cm (3.3
ft.)
Approximately 150 cm (4.9
ft.)
Approximately 60 cm (2.0 ft.)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles
that are extremely close to the
vehicle.
The range of the sensors may
change depending on the shape of
the object etc.
