■ Camera sensor (P. 290)
Observe the following to ensure that the LKA system functions correctly.
●Keep the windshield clean at all times.

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.
