intentionally across a lane marker, the LDW
alert may not be given. Do not expect the
LDW alert to occur when you are
intentionally crossing the lane marker.
Warning
The LKA system does not continuously
steer the vehicle. It may not keep the
vehicle in the lane or give a Lane
Departure Warning (LDW) alert, even if a
lane marking is detected.
The LKA and LDW systems may not:
Provide an alert or enough steering
assist to avoid a lane departure or
crash.
Detect lane markings under poor
weather or visibility conditions. This
can occur if the windshield or
headlamps are blocked by dirt, snow,
or ice; if they are not in proper
condition; or if the sun shines directly
into the camera.
Detect road edges.
Detect lanes on winding or hilly roads.
Warning (Continued)
If LKA only detects lane markings 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
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.
Using LKA on slippery roads could cause
loss of control of the vehicle and a crash.
Turn the system off.

Warning
Driving and Operating
Warning
LKA will not alert the driver if a towed
trailer crosses into an adjacent lane of
travel. Serious injury or property damage
may occur if the trailer moves into
another lane. Always monitor the trailer
position 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 an
LDW when intentionally steering across a
lane marker.
To turn LKA on and off, press
instrument panel 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. In some vehicles,
you must press the button for more than
three seconds to turn LKA off.
