Warning (Continued)
while towing to make sure it
is within the same lane as
the tow vehicle.
How the System Works
LKA uses a camera sensor
installed on the windshield
ahead of the rearview mirror
to detect lane markings. It may
provide brief steering assist if
it detects an unintended lane
departure. It may further
provide an audible alert or the
driver seat may pulse
indicating that a lane marking
has been crossed. The system
does not provide a Lane
Departure Warning (LDW)
when intentionally steering
across a lane marker.
To turn LKA on and off, press
A
on the center stack.
If equipped, the indicator light
on the button comes on when
LKA is on and turns off when
LKA is disabled. In some
vehicles, a long press of over
three seconds is required to
turn LKA off.
When on,
A
is white,
if equipped, indicating that the
system is not ready to assist.
A
is green if LKA is ready to
assist. LKA may assist by
gently turning the steering
wheel if the vehicle
approaches a detected lane
marking.
A
is amber when
assisting. It may also provide a
Lane Departure Warning
(LDW) alert by flashing
A
amber if the vehicle crosses a
detected lane marking.
Additionally, there may be
three beeps, or the driver seat
may pulse three times, on the
right or left, depending on the
lane departure direction.
Take Steering
The LKA system does not
continuously steer the vehicle.
If LKA does not detect active
driver steering, an alert and
chime may be provided. Steer
the vehicle to dismiss. LKA
may become temporarily
unavailable after repeated
take steering alerts.
When the System Does
Not Seem to Work
Properly
The system performance may
be affected by:
.
Close vehicles ahead.
.
Sudden lighting changes,
such as when driving
through tunnels.
.
Banked roads.
.
Roads with poor lane
markings, such as two-lane
roads.
If the LKA system is not
functioning properly when lane
markings are clearly visible,
cleaning the windshield
may help.
A camera blocked message
may display if the camera is
blocked. Some driver
assistance systems may have
reduced performance or not
