●
tions.
While the lane lines cannot be recognized while driving.

●

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 or when the temper-
■
ature in the cabin is extremely low
The LKA system functions may not be available for a while after driving of the vehi-
cle has been started. In such cases, turn the LKA system off and turn it on again
after normal temperature returns. When the temperature in the cabin decreases or
increases, and the temperature around the camera sensor becomes appropriate
for its operation, the functions will begin operating. (P. 240)
