alert when approaching the lane
on the side where it has detected
a lane marking. Even with LKA
and LDW, you must steer the
vehicle. Always keep your
attention on the road and
maintain proper vehicle position
within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield, headlamps, and
camera sensors clean and in
good repair. Do not use LKA in
bad weather conditions or on
roads with unclear lane markings,
such as construction zones.
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
the driver seat may pulse indicating
that a lane marking has been
crossed.
To turn LKA on and off, press
on the center console. If equipped,
the indicator light on the button
comes on when LKA is on and turns
off when LKA is disabled.

three beeps, or the driver seat may
pulse three times, on the right or

steering, an alert and chime may be
provided. Steer the vehicle to

Seem to Work Properly

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.
