on one side of the road, it will
only assist or provide an LDW
alert when approaching the lane
on the side where it has detected
a lane marking. Even with LKA

vehicle. Always keep your

Warning
Using LKA while towing a trailer
or on slippery roads could cause
loss of control of the vehicle and
a crash. Turn the system off.
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
driver seat may pulse indicating that
a lane marking has been crossed.
To turn LKA on and off, press
A
to the left of the steering wheel.
If equipped, the indicator light on the
button comes on when LKA is on
and turns off when LKA is disabled.
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 and alert if the
vehicle crosses detected markings
on one or both sides of the lane.
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.
