When driving
Functions included in the LKA
Lane departure warning function
If the system judges th at the vehicle may deviate from its lane, it
alerts the driver using beeping, screen displays and a sensory
warning
* given via the steering wheel.
*: A slight steering torque is applied for a short period of time in the direc- tion of the center of the lane.
Lane keeping assist function
• This function will be active wh en the vehicle-to-vehicle distance
control mode of the cruise control ( P. 273) is set with vehicle
speed above approximately 45 mph (72 km/h) 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 the driver maintain the vehicle
inside the lane.
The lane keeping assist function will be temporarily canceled if the steer-
ing wheel is not operated, or if you continue driving with your hands
lightly touching the steering wheel. ( P. 295)

■No-handed driving warning
If the steering wheel is not operated for approximately 15 seconds on a
straight road or approximately 5 seconds on a curve, the buzzer will beep
twice, indicators on the multi-information display will flash, and the lane
keeping assist function will be temporarily canceled. If you drive the vehicle
with your hands lightly touching the steering wheel, this may also be
detected as no-handed driving.
■ After the vehicle has been parked in the sun
The LKA system functions may not be available and a warning message
(P. 524) will be displayed for a while after driving has 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 and the temperature
around the camera sensor ( P. 290) becomes suitable for its operation, the
functions will begin to operate.
■ If there are lane markers on only one side of the vehicle
The lane keeping assist function will not operate. Also, the lane departure
warning will not operate for the side on which lane markers could not be rec-
ognized.
■ Conditions in which the func tion 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 operate incorrectly, or the lane keeping assist function
may not operate properly. However, this does not indicate a malfunction.
● When driving through an area with no lane markers, such as a tollbooth,
a crossing or before a ticket checkpoint
● When driving on a sharp curve
● When lanes are extremely narrow or extremely wide
● When the vehicle leans to one side an unusual amount due to a heavy
load or improper tire inflation pressure
● When the following distance between your vehicle and the vehicle ahead
is extremely short
