Lka (Lane-Keeping Assist) - Lexus LS600hl Quick Manual

LKA (Lane-Keeping Assist) (if equipped)
While driving on a freeway or motor highway that has lane markers and no sharp curves,
the system recognizes the lanes using a camera located above the inside rear view mir-
ror as a sensor to assist the driver with staying in the lane. The LKA system has two func-
tions.
Lane departure warning function
1
If the system judges that the vehicle may deviate from its lane, it alerts the driver using
rapid beeping, indications on the multi-information display, 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 control mode of the
dynamic radar cruise control with full-speed range 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.
