2-4. Using other driving systems
While driving on a freeway or motor highway that has lane markings, this
system recognizes the lanes using a camera as a sensor to assist the driver
with staying in the lane. The LKA system has two functions.
■ 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-infor-
mation display, and sensory warning* 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 vehicle-to-vehicle distance control
mode of the cruise control (P. 214) is set with vehicle speed above
approximately 45 mph (72 km/h) 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 in a central position within the lane.
■ Turning the LKA system on
The lane departure warning function and lane keeping assist func-
tion will be activated depending on the recognition condition of lane
markings, vehicle speed and the setting of radar cruise control
(vehicle-to-vehicle distance control mode).
Press the “LKA” switch to acti-
vate the system.
Press the switch again to turn
the LKA system off.
