• When driving on a road with clear lane

tion.

Use the function only on highways and
expressways.
If the adaptive cruise control is not operat-
ing, the function will not operate.
Refer to “Adaptive cruise control (if
equipped)” (P.5-98) or “Adaptive cruise
control (with following function for all
speeds)” (P.5-110).
In situations where the lane lines are diffi-
cult to see or are not visible, such as when
in a traffic jam, support will be provided
using the path of preceding and surround-
ing vehicles.
If the system determines that the steering
wheel has not been operated for a certain
amount of time or the steering wheel is not
being firmly gripped, the driver will be
alerted via a display and this function will
be temporarily canceled.
If the function is deactivated, use the lane
keep assist ON/OFF switch to turn on the
system.

area around the vehicle and carefully
operate the steering wheel to move the
vehicle back to the center of the lane.
