NOTICE
■Camera sensor (P. 2 3 4 )
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, conden-
sation 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 ai r blowing to the feet may allow the upper
part of the windshield to fog up. This will have a negative effect on the images.

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 your Lexus dealer.

remove it. The direction of the camera sensor is precisely adjusted.
●Do not subject the camera sensor to stro ng impact or force, and do not disas-

■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air mode.
●During use, various odors from inside an d outside the vehicle may enter into and
accumulate in the air condit ioning system. This may then cause odor to be emitted
from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditio ning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immedi- ately after the air conditioning system is started in automatic mode.

ence between the temperature of the outs ide air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
