
When the lane departure warning function is activated
The lane departure warning function will be temporarily canceled and will
not resume until a few seconds elapse after it is activated.

Hands-free driving warning
If the steering wheel is not operated for about 15 seconds on a straight road
or about 5 seconds on a curve, the signal will beep twice, indications on the
multi-information display will flash, and the lane keeping assist function
will be temporarily cancelled. If you drive the vehicle with your hands
lightly touching the steering wheel, it may also be detected as hands-free
driving.

When the vehicle has been parked under the scorching sun
The LKA system functions may not operate for a while when driving first
commences. The functions will become operational once the cabin tempera-
ture decreases and the camera's surrounding area returns to an appropriate
temperature. Therefore, turn the LKA system off, and after a while turn it
back on. (P. 280)
