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.
LDP SYSTEM OPERATION
The LDP system operates above approxi-
mately 45 MPH (70 km/h) and when the
lane markings are clear.
If the vehicle approaches either the left or
right side of the traveling lane, the driver
assist system lane indicator (orange) in the
vehicle information display will blink and a
warning chime will sound. Then, the LDP
system will automatically 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 will not operate or will stop
operating and only a warning chime will
sound under the following conditions.
— When the steering wheel is turned as
far as necessary for the vehicle to
change lanes.
— When the accelerator pedal is de-
pressed.
— 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)
approach warning occurs.
— When the BSI system activates.
— When the hazard warning flashers
are operated.
— When driving on a curve at a high
speed.
— When the brake pedal is depressed.
(models without Direct Adaptive
Steering)
. 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.

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.

BSW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the BSW system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
. The BSW system cannot detect all
vehicles under all conditions.
. The radar sensors may not be able to
detect and activate BSW when cer-
tain objects are present such as:
— Pedestrians, bicycles, animals.
— Vehicles such as motorcycles, low height vehicles, or high ground
clearance vehicles.
Starting and driving5-43

5-44Starting and driving
— Oncoming vehicles.
— Vehicles remaining in the detec-tion zone when you accelerate
from a stop.
— A vehicle merging into an adja- cent lane at a speed approxi-
mately the same as your vehicle.
— A vehicle approaching rapidly from behind.
— A vehicle which your vehicle over- takes rapidly.
— A vehicle that passes through the detection zone quickly.
. The radar sensor’s detection zone is
designed based on a standard lane
width. When driving in a wider lane,
the radar sensors may not detect
vehicles in an adjacent lane. When
driving in a narrow lane, the radar
sensors may detect vehicles driving
two lanes away.
. The radar sensors are designed to
ignore most stationary objects, how-
ever objects such as guardrails, walls,
foliage and parked vehicles may oc-
casionally be detected. This is a
normal operation condition.
. The following conditions may reduce
the ability of the radar to detect other vehicles:
— Severe weather
— Road spray
— Ice/frost/snow build-up on the vehicle
— Dirt build-up on the vehicle
. Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint near
the radar sensors. These conditions
may reduce the ability of the radar to
detect other vehicles.
. Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound,
and it may not be heard.BSW DRIVING SITUATIONS

BSI SYSTEM OPERATION
The BSI system operates above approxi-
mately 37 MPH (60 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side indicator light
illuminates.
If the turn signal is then activated, the
system chimes (twice) and the side indicator
light flashes. The side indicator light con-
tinues to flash until the detected vehicle
leaves the detection zone.
If the BSI system is ON and your vehicle
approaches a lane marker while another
vehicle is in the detection zone, the system
chimes (three times) and the side indicator
light flashes. The BSI system activates to
help return the vehicle back to the center of
the driving lane. The BSI system operates
regardless of turn signal usage.
NOTE:
.BSI warning and system application will
only be activated if the side indicator
light is already illuminated when your
vehicle approaches a lane marker. If
another vehicle comes into the detection
zone after your vehicle has crossed a
lane marker, no BSI warning or system
application will be activated. (For addi-
tional information, see “BSI driving
situations” (P.5-55).)
