HOW TO ENABLE/DISABLE THE
LDW SYSTEM
Perform the following steps to enable or
disable the LDW system.
1. Push the MENU button
and touch
[Driver Assistance] on the lower display.
2. Touch [Lane Assist].
3. Touch [Lane Departure Warning] to enable or disable the system.
The displayed keys on the lower display may
vary depending on models, specifications
and software versions.
LDP SYSTEM OPERATION (if so
equipped)
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 on the vehicle information display
will flash and a warning chime will sound.
Then, the LDP system will automatically
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.

— On roads where the discontinuedlane markers are still detectable.
— On roads where there are sharp curves.
— On roads where there are sharply contrasting objects, such as sha-
dows, snow, water, wheel ruts,
seams or lines remaining after
road repairs. (The LDW and LDP
(if so equipped) systems could
detect these items as lane mar-
kers.)
— 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.
SYSTEM TEMPORARILY UNA-
VAILABLE
Condition A
The warning and assist functions of the
LDW and LDP (if so equipped) systems are
not designed to work under the following
conditions:
.When you operate the lane change signal
and change the traveling lanes in the
direction of the signal. (The LDP system
(if so equipped) will be deactivated for
approximately 2 seconds after the lane
change signal is turned off.)
. When the vehicle speed lowers to less
than approximately 45 MPH (70 km/h). .
When the Blind Spot Intervention
®(BSI)
system (if so equipped) activates an
audible warning or brake control.
After the above conditions have finished and
the necessary operating conditions are sa-
tisfied, the warning and assist functions will
resume.
Condition B
The assist function of the LDP system (if so
equipped) is not designed to work under the
following conditions (warning is still func-
tional):
. 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 depressed
while the brake control assist is provided.
. When the Intelligent Cruise Control (ICC)
(if so equipped) approach warning oc-
curs.
. When the hazard warning flashers are
operated.
. When driving on a curve at high speed.
After the above conditions have finished and
the necessary operating conditions are sa-
tisfied, the LDP assist function (if so
equipped) will resume.
