Lane departure warning function
If the system judges that the vehicle may deviate from its lane, it alerts
the driver using rapid beeping, indications on the multi-information dis-
play, and a sensory warning* given via the steering wheel.
*: A slight steering torque is applied for a short period of time in the direction of the
center of the lane.
Lane keeping assist function
• This function will be active when the vehicle-to-vehicle distance con-
trol mode of the dynamic radar crui se control with full-speed range
( P. 328) is set with vehicle speed above approximately 72 km/h
(45 mph) and while the lane departure warning function is active.
• When the lane keeping assist function is active, a slight steering
torque will be applied, to help th e driver maintain the vehicle inside
the lane.
The lane keeping assist function will be temporarily canceled if the steering
wheel is not operated, or if you continue driving with your hands lightly touch-
ing the steering wheel. ( P. 349)

will not operate for the side on which lane markers could not be recognized.
■Conditions in which the function may not operate correctly
In the following conditions, the LKA system functions may not operate, or it may not
be possible to ensure adequate performance. Also, the camera sensor may be
unable to recognize lane lines causing the lane departure warning function to oper-
ate incorrectly, or the lane keeping assist function may not operate properly. How-
ever, this does not indicate a malfunction.

■Warning messages for LKA
Warning messages are used to indicate a system malfunction or to inform the driver
of the need for caution while driving. ( P. 614)
CAUTION
■Before using the LKA system
Do not rely solely on the LKA system. The LKA system does not drive the vehicle
automatically, nor does it reduce the amount of care you need to take. As such, the
driver must always assume full responsibility for understanding his/her surround-
ings, for operating the steering wheel to correct the driving line, and for driving
safely.
Inappropriate or negligent driving could lead to an accident.
■To avoid operating the LKA by mistake
Switch the LKA off using the LKA switch when not in use.
