LANE KEEPING ASSIST (LKA)
Lane Keeping Assist is designed to help
detect lane markings (or road edges)
while driving over a certain speed. Lane
Keeping Assist will warn the driver if the
vehicle leaves the lane without using the
turn signal, or will automatically assist
the driver’s steering to help prevent the vehicle from departing the lane.
Detecting sensor
ONX4E050146[1] : Front view camera

detecting sensor to detect lane markings
(or road edges).
Refer to the picture above for the
detailed location of the detecting sensor.
CAUTION
For more details on the precautions
of the front view camera, refer to
“Forward Collision-Avoidance Assist
(FCA)” section in chapter 7.

and to maintain the vehicle in its
lane.
• The hands–off warning message
may appear late depending on road
conditions. Always have your hands
on the steering wheel while driving.
• If the steering wheel is held very
lightly, the hands–off warning
message may appear because Lane
Keeping Assist may not recognize
that the driver has their hands on the
steering wheel.
• If you attach objects to the steering
wheel, the hands-off warning may
not work properly.
Information
• You may change settings from the
instrument cluster (User Settings) or
infotainment system (Vehicle Settings),
whichever option that is provided with
your vehicle. For more details, see
"User Settings" section in chapter 4, or

warning is generated, Lane Keeping
Assist warning message may not be
displayed and audible warning may
not be generated.

wheel, steering may not be assisted
properly.
