.Lane Departure Warning (LDW) system
— warns the driver with a warning light and chime that the vehicle is begin-
ning to leave the driving lane.
. Lane Departure Prevention (LDP) system
— warns the driver with a warning light and chime, and helps assist the driver
to return the vehicle to the center of
the traveling lane by applying the
brakes to the left or right wheels
individually (for a short period of
time).

The LDW and LDP systems use a camerainstalled behind the windshield to monitor
the lane markers of your traveling lane.

LDW SYSTEM OPERATION
The LDW system operates above approxi-
mately 45 MPH (70 km/h) and the lane
markings are clear.
If the vehicle approaches either the left or
right side of the traveling lane, the LDW
indicator light (orange) on the instrument
panel will flash and a warning chime will
sound.
NOTE:
The LDW system is not designed to warn
when you operate the lane change signal
and change traveling lanes in the direction
of the signal. (The LDW system will become
operable again approximately 2 seconds
after the lane change signal is turned off.)

LDP SYSTEM OPERATION
The LDP system operates above approxi-
mately 45 MPH (70 km/h) and the lane
markings are clear.
If the vehicle approaches either the left or
right side of the traveling lane, the LDW
indicator light (orange) on the instrument
panel will flash and a warning chime will
sound. Then, the LDP system will automa-
tically apply the brakes for a short period of
time to help assist the driver to return the
vehicle to the center of the traveling lane.
NOTE:
.The LDP system is not designed to work
when you operate the lane change signal
and change traveling lanes in the direc-
tion of the signal. (The LDP system will
become operable again approximately 2
seconds after the lane change signal is
turned off.)
. The LDP braking assist will not operate
or will stop operating and only a warn-
ing chime will sound under the following
conditions.
— When the brake pedal is depressed.
— When the steering wheel is turned as
far as necessary for the vehicle to
change lanes.
— When the accelerator pedal is de-
pressed while brake control assist is provided.
— When the Intelligent Cruise Control
(ICC), Distance Control Assist (DCA),
Blind Spot Intervention (BSI), Blind
Spot Warning (BSW), Predictive For-
ward Collision Warning (PFCW) or
Forward Emergency Braking (FEB)
warnings sound.
— When the hazard warning flashers
are operated.
— When driving on a curve at a high
speed.
. While the LDP system is operating, you
may hear a sound of brake operation.
This is normal and indicates that the
LDP system is operating properly.

LDW/LDP SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the LDW and LDP systems. Failure to
operate the vehicle in accordance with
these system limitations could result in
serious injury or death.
.The system will not operate at speeds
below 45 MPH (70 km/h) or if it
cannot detect lane markers.
. The LDP system is primarily intended
for use on well-developed freeways
or highways. It may not detect the
lane markers in certain roads, weath-
er or driving conditions.
. Do not use the LDP system under the
following conditions as it may not
function properly:
— During bad weather (rain, fog, snow, etc.).
— When driving on slippery roads, such as on ice or snow, etc.
— When driving on winding or un- even roads.
— When there is a lane closure due to road repairs. — When driving in a makeshift or
temporary lane.
— When driving on roads where the lane width is too narrow.
— When driving without normal tire conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, non-stan-
dard wheels).
— When the vehicle is equipped with non-original brake parts or sus-
pension parts.
— When you are towing a trailer or other vehicle.
. The camera may not detect lane
markers in the following situations
and the LDW and LDP systems may
not operate properly.
— On roads where there are multi- ple parallel lane markers, lane
markers that are faded or not
painted clearly, yellow painted
lane markers, non-standard lane
markers, or lane markers covered
with water, dirt, snow, etc.
— On roads where the discontinued lane markers are still detectable.
— On roads where there are sharp curves.
Page 279 of 524

— On roads where there are sharplycontrasting objects, such as sha-
dows, snow, water, wheel ruts,
seams or lines remaining after
road repairs. (The LDW and LDP
systems could detect these items
as lane markers.)
— On roads where the traveling lane merges or separates.
— When the vehicle’s traveling di- rection does not align with the
lane marker.
— When traveling close to the ve- hicle in front of you, which ob-
structs the lane camera unit
detection range.
— When rain, snow or dirt adheres to the windshield in front of the
lane camera unit.
— When the headlights are not bright due to dirt on the lens or
if the aiming is not adjusted
properly.
— When strong light enters the lane camera unit. (For example, the
light directly shines on the front
of the vehicle at sunrise or sun-
set.) — When a sudden change in bright-
ness occurs. (For example, when
the vehicle enters or exits a tunnel
or under a bridge.)
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
