208 Driving and Operating
{ Warning
T
he LKA system does not continuously
st
eer 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 alane
marking. Even with LKA and LDW, you
must steer the vehicle. Always keep your
(Continued)
Warning (Continued)
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
U
sing LKA on slippery roads could cause loss
o
f control of the vehicle and acrash. Turn
the system off.
{ Warning
L
KA will not alert the driver if a towed trailer
c
rosses 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
LK
A 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 aLane Departure
Warning (LDW) when intentionally steering
across alane marker.
To turn LKA on and off, press A on the
infotainment screen. If equipped, the indicator
light on the button comes on when LKA is on
and turns off when LKA is disabled.
When on, n is white, if equipped, indicating
that the system is not ready to assist. n is
green if LKA is ready to assist. LKA may assist
by gently turning the steering wheel if the
vehicle approaches adetected lane marking.
n is amber when assisting. It may also
provide aLane Departure Warning (LDW) alert
by flashing n 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.
