system is located inside the map light
cover. To keep the proper operation of the
LDW/LDP systems and prevent a system
malfunction, be sure to observe the follow-
ing:
. Always keep the windshield clean.
. Do not attach a sticker (including
transparent material) or install an
accessory near the camera unit.
. Do not place reflective materials, such
as white paper or a mirror, on the

Detection zone
The radar sensors can detect vehicles on
either side of your vehicle within the
detection zone shown as illustrated. This
detection zone starts from the outside
mirror of your vehicle and extends approxi-
mately 10 ft (3 m) behind the rear bumper,
and approximately 10 ft (3 m) sideways.
The BSW system operates above approxi-
mately 20 MPH (32 km/h). If the radar
sensors detect a vehicle in the detection
zone, the the Blind spot warning indicator
light illuminates. If the driver then acti-
vates the turn signal, a chime will sound
twice and the Blind spot warning indicator
light will flash. The Blind Spot Intervention
TMsystem
operates above approximately 37 MPH
(60 km/h). If the system detects a vehicle
in the detection zone and your vehicle is
approaching the lane marker, the Blind
Spot Intervention
TMsystem provides an
audible warning (three times), flashes the
Blind spot warning indicator light and
slightly applies the brakes for a short
period of time on one side to help return
the vehicle back to the traveling lane. The
Blind Spot Intervention
TMsystem provides
an audible warning and turns on or flashes
the Blind spot warning indicator light even
if the BSW system is off.
WARNING
. The BSW and Blind Spot InterventionTM
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 direction you will move
to ensure it is safe to change lanes.
Never rely solely on the BSW or Blind
Spot Intervention
TMsystem. .
Using the Blind Spot Intervention
TM
system under some road, lane marker
or weather conditions could lead to
improper system operation. Always rely
on your own steering and braking
operation to avoid accidents.
. The BSW and Blind Spot Intervention
TM
systems may not provide a warning or
brake control for vehicles that pass
through the detection zone quickly.

BLIND SPOT INTERVENTIONTMSYS-
TEM OPERATION
If the radar sensors detect vehicles in the
detection zone, the Blind spot warning
indicator light located inside the outside
mirrors illuminates. If your vehicle is
approaching a lane marker, the Blind spot
warning indicator light flashes and an
audible warning will sound three times.
Then the system applies the brakes on one
side of the vehicle for a short period of
time to help return the vehicle back to the
center of the lane. Blind Spot Interven-
tion
TMoperates regardless of turn signal usage.
NOTE:
.
Warning and brake control will only be
activated if the Blind spot warning
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 warning
or brake control will be activated. (See
“BSW/Blind Spot Intervention
TMdriv-
ing situations” later in this section.)
. The Blind Spot Intervention
TMsystem is
typically activated earlier than the
Lane Departure Prevention (LDP) sys-
tem when your vehicle is approaching
a lane marker.
The Blind Spot Intervention
TMsystem turns
on when the dynamic driver assistance
switch on the steering wheel is pushed
when the “Blind Spot Intervention” is
enabled in the settings menu on the center
display. The Blind Spot Intervention
TMON
indicator light (green) on the instrument
panel illuminates when the Blind Spot
Intervention
TMsystem is turned on.
The Blind Spot InterventionTMsystem
provides an audible warning and flashes the indicator light when Blind Spot Inter-
vention
TMis activated even if the BSW
system is off.

Precautions on BSW/Blind Spot
InterventionTMsystem
WARNING
.Do not use the Blind Spot InterventionTM
system under the following conditions
because the system may not function
properly.
—During bad weather (for example,
rain, fog, snow, wind, etc.)
—When driving on slippery roads,such as on ice or snow, etc.
—When driving on winding or uneven
roads.
—When there is a lane closure due toroad repairs.
—When driving in a makeshift lane.
—When driving on roads where thelane width is too narrow.
—When driving with a tire that is notwithin normal tire conditions (for
example, tire wear, low tire pressure,
installation of spare tire, tire chains,
non-standard wheels).
—When the vehicle is equipped withnon-original brake parts or suspen-
sion parts.
. Do not use the BSW or Blind Spot
Intervention
TMsystems when towing a
trailer.
. Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound, and
it may not be heard.
. The radar sensors may not be able to
detect and activate Blind Spot Interven-
tion
TM/BSW when certain objects are
present such as:
—Pedestrians, bicycles, animals
—Several types of vehicles such as motorcycles
—Oncoming vehicles
—Vehicles remaining in the detectionzone when you accelerate from a
stop
(See “BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
—A vehicle merging into an adjacent lane at a speed approximately the same as your vehicle
(See
“BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
—A vehicle approaching rapidly from behind.
(See “BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
—A vehicle which your vehicle over-
takes rapidly.
(See “BSW/Blind Spot Intervention
TM
driving situations” later in this sec-
tion)
. Severe weather or road spray conditions
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 vehi-
cles 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, however ob-
jects such as guardrails, walls, foliage

The BCI system uses radar sensors*1
installed on both sides near the rear
bumper to detect an approaching vehicles
and sonar sensors
*2to detect objects in
the rear.
The radar sensors
*1detect the approach-
ing vehicle from up to approximately 49 ft
(15 m) away. The sonar sensors
*2detect
a rear obstacle at up to approximately 4.9
ft (1.5 m) from the bumper. Refer to the
illustration for approximate zone coverage
areas
*3.
If the radar detects a vehicle approaching
from the side or the sonar detects close
objects in the rear, the system gives visual and audible warnings, and applies the
brake for a moment when the vehicle is
moving backwards. After the automatic
brake application, the driver must depress
the brake pedal to maintain brake pres-
sure. If the driver’s foot is on the accel-
erator pedal, the system pushes the
accelerator upward before applying the
brake. If you continue to press the accel-
erator, the system will not engage the
brake.
WARNING
.
The BCI system is not a replacement for
proper driving procedure and is not
designed to prevent contact with vehi-
cles or objects. When backing out of
parking space, always use the inside
and outside rearview mirrors and turn
and look in the direction you will move.
Never rely solely on the BCI system.
. There is a limitation to the detection
capability of the radar or the sonar.
Using the BCI system under some road,
ground, lane marker, traffic or weather
conditions could lead to improper sys-
tem operation. Always rely on your own operation to avoid accidents.
