Driver Alert System*
Lane Keeping Aid (LKA)
See page 187 for information about determin-
ing if your vehicle is equipped with Lane
Departure Warning or Lane Keeping Aid
This function is designed to help reduce the
risk of accidents in situations where the vehi-
cle unintentionally leaves its lane and there is
a risk of driving off the road or into the oppo-
site lane. It is primarily intended for use on
highways or other major roads with clearly
04
marked side marker and center lines.
How LKA works
The illustration is generic
LKA uses the camera located at the center,
upper edge of the windshield to monitor the
road's/lane's side marker lines.
Models with 4-cylinder engines only.

If the vehicle crosses a side marker line or the
road's center dividing line, LKA will provide
active steering assistance to help steer it
back into the lane.
The driver will also be alerted by vibrations in
the steering wheel.
WARNING
This feature is only intended to assist the
driver and does not function in all driving,
weather, traffic or road conditions.
As the driver, you have full responsibility
for operating the vehicle in a safe manner.
Operation and function
LKA is active at speeds above 40 mph
(65 km/h) on highways or other major roads
with clearly marked side/lane marker and
center lines. On narrow roads where the dis-
tance between side/lane marker lines is less
than approximately 8.5 feet ( 2.6 meters), LKA
will be temporarily deactivated.
LKA monitors and follows the marker lines (the
red lines in the illustration)
•
White side marker lines: the function is
active and "sees" one or both of the
road's side marker lines.
•
Gray side marker lines: the function is
active but cannot "see" one or both of the
road's side marker lines.
