LDW system operation
The LDW system provides a lane departure
warning function when the vehicle is driven
at speeds of approximately 45 MPH (70
km/h) and above. When the vehicle
approaches either the left or the right side
of the traveling lane, a warning chime will
sound and the driver assist system lane
indicator (orange) in the vehicle informa-
tion display will blink to alert the driver.
The warning function will stop when the
vehicle returns inside of the lane markers.
The LDW system is not designed to warn
under the following conditions..
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.)
. When the vehicle speed lowers to less
than approximately 45 MPH (70 km/h).
. When the Blind Spot Intervention
TM
(BSI) system activates an audible warn-
ing or steering control.
After the above conditions have finished
and the necessary operating conditions are
satisfied, the LDW functions will resume.

Driver assist system lane indicator
LDP system operation
The LDP system provides a lane departure
warning and steering control assistance
when the vehicle is driven at speeds of
approximately 45 MPH (70 km/h) and
above. When the vehicle approaches either
the left or the right side of the traveling
lane, a warning chime will sound and the
driver assist system lane indicator (orange)
will blink to alert the driver. Then, the LDP
system will automatically apply the steer-
ing for a short period of time to help assist
the driver to return the vehicle to the center
of the traveling lane.

Side indicator light
The BSW system operates above approxi-
mately 20 MPH (32 km/h). If the radar
sensors detect vehicles in the detection
zone, the side indicator light illuminates. If
the driver then activates the turn signal, a
chime will sound twice and the side
indicator light will flash.
The BSI system operates above approxi-
mately 37 MPH (60 km/h). If the system
detects a vehicle in the detection zone and
your vehicle is approaching the lane
marker, the BSI system provides an audi-
ble warning (three times), flashes the side
indicator light and slightly applies the
steering for a short period of time to help return the vehicle back to the traveling
lane. The BSI system provides an audible
warning and turns on or flashes the side
indicator light even if the BSW system is
off.
WARNING
.
The BSW and BSI systems are not a
replacement for proper driving procedure
and are not designed to prevent contact
with vehicles or objects. When changing
lanes, always use the side and rear
mirrors and turn and look in the direc-
tion you will move to ensure it is safe to
change lanes. Never rely solely on the
BSW or BSI system.
. Using the BSI system under some road,
lane marker or weather conditions could
lead to improper system operation. Al-
ways rely on your own steering and
braking operation to avoid accidents.
. The BSW and BSI systems may not
provide a warning or steering control
for vehicles that pass through the
detection zone quickly.
SSD1028
Side indicator light
BSW system operation
If the radar sensors detect vehicles in the
detection zone, the side indicator light
located inside the vehicle (near the outside
mirrors) illuminates. If the turn signal is
then activated, the side indicator light
flashes and a chime sounds twice. The
side indicator light continues to flash until
the detected vehicles leave the detection
zone.
The side indicator lights illuminate for a
few seconds when the ignition switch is
placed in the ON position.

The brightness of the side indicator lights
is adjusted automatically depending on the
brightness of the ambient light.
A chime sounds if the radar sensors have
already detected vehicles when the driver
activates the turn signal. If a vehicle comes
into the detection zone after the driver
activates the turn signal, then only the side
indicator light flashes and no chime
sounds. (See“BSW/BSI driving situations”
(P.5-43).)

Side indicator light
BSI system operation
If the radar sensors detect vehicles in the
detection zone, the side indicator light
located inside the vehicle (near the outside
mirrors) illuminates. If your vehicle is
approaching a lane marker, the side
indicator light flashes and an audible
warning will sound three times. Then the
system applies the steering for a short
period of time to help return the vehicle
back to the center of the lane. BSI operates
regardless of turn signal usage.NOTE:
.
Warning and steering control will only
be activated if the side indicator light
is already illuminated when your vehi-
cle approaches a lane marker. If
another vehicle comes into the detec-
tion zone after your vehicle has
crossed a lane marker, no warning or
steering control will be activated. (See
“BSW/BSI driving situations” (P.5-43).)
. The BSI system is typically activated
earlier than the Lane Departure Pre-
vention (LDP) system when your vehi-
cle is approaching a lane marker.

.The radar sensors may not be able to
detect and activate BSI/BSW when
certain objects are present such as:
— Pedestrians, bicycles, animals
— Several types of vehicles such as
motorcycles
— Oncoming vehicles
— Vehicles remaining in the detection
zone when you accelerate from a
stop
— A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle
— A vehicle approaching rapidly from
behind.
— A vehicle which your vehicle over-
takes rapidly.
See also “BSW/BSI driving situations”
(P.5-43) for the situations in which the
radar sensors may not be able to detect
vehicle(s).
. Severe weather or road spray condi-
tions may reduce the ability of the
radar to detect other vehicles.
. The radar sensors’ 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 occa-
sionally be detected. This is a normal
operating condition.
. The camera may not detect lane mar-
kers in the following situations and the
BSI system may not operate properly.
— On roads where there are multiple
parallel lane markers; lane markers
that are faded or not painted clearly;
yellow painted lane markers; non-
standard lane markers; lane mar-
kers covered with water, dirt, snow,
etc.
— On roads where discontinued lane
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. —
On roads where the traveling lane
merges or separates.
— When the vehicle’s traveling direc-
tion does not align with the lane
markers.
— When traveling close to the vehicle
in front of you, which obstructs the
lane camera unit detection range.
— When rain, snow or dirt adheres to
the windshield in front of a lane
camera unit.
— When the headlights are not bright
due to dirt on the lens or if aiming is
not adjusted properly.
— When strong light enters a lane
camera unit. (For example, light
directly shines on the front of the
vehicle at sunrise or sunset.)
— When a sudden change in bright-
ness occurs. (For example, when the
vehicle enters or exits a tunnel or
under a bridge.)
