Lane Keep Assist (LKA)

The LKA system does not continuously
s
teer 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.
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

Warning (Continued)
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.

Using LKA while towing atrailer or on
s
lippery roads could cause loss of control of
the vehicle and a crash. Turn the system off.
If equipped, LKA may help avoid crashes
d
ue to unintentional lane departures. This
system uses acamera to detect lane markings.
The LKA system can be ready to assist
above approximately 50 km/h (31 mph). LKA
may assist by gently turning the steering
wheel if the vehicle approaches adetected
lane marking. It may also provide aLane
Departure Warning (LDW) alert if the vehicle
unintentionally crosses adetected lane
marking. LKA will not assist or alert if the
t
urn signal is active in the direction of the
lane departure, or if it detects that you are
accelerating, braking, or actively steering. LKA
can be overridden by turning the steering
wheel. If the system detects you are steering
intentionally across alane marker, the LDW
may not be given. Do not expect the LDW
to occur when you are intentionally crossing
alane marker.
How the System Works
The LKA camera sensor is on the windshield
ahead of the rearview mirror.
To turn LKA on and off, press A on the
center stack.
LKA may not be available in extremely cold
temperatures of less than approximately −30°
f (−34° c).
When on, A is white and changes green if
LKA is available to assist and provide LDW
alerts. It may assist by gently turning the
steering wheel and display A as amber if
the vehicle approaches a detected lane marking
without using aturn signal in that direction. It
may also provide an LDW alert by flashing
A amber as the lane marking is crossed.
