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. Then the BSI system slightly
applies the brakes to help return the vehicle
back to the center of the driving lane. The
BSI system operates regardless of turn
signal usage.
NOTE:
.Warning and system application of the
brakes 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 warning or
system application of the brakes will be
activated. (See “BSI driving situations” (P.5-45).)
. The BSI system is typically activated
earlier than the Lane Departure Preven-
tion (LDP) system when your vehicle is
approaching a lane marker.

— On roads where discontinued lanemarkers 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 di- rection does not align with the
lane markers.
— 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 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.)
. Do not use the BSI system under the
following conditions because the sys-
tem may not function properly.
— During bad weather. (For exam- ple: 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 with a tire that is not within normal tire conditions
(for example, tire wear, low tire
pressure, installation of spare tire,
tire chains, non-standard wheels).
— When the vehicle is equipped with non-original brake parts or sus-
pension parts. — When towing a trailer or other
vehicle.
. Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound,
and it may not be heard.

.In the case of several vehicles approach-
ing in a row (Illustration 1) or in the
opposite direction (Illustration 2), a
chime may not be issued to the BCI
system after the first vehicle passes the
sensors.
. The sonar system chime indicating there
is an object behind the vehicle has a
higher priority than the BCI chime (single
beep) indicating an approaching vehicle.
If the sonar system detects an object
behind the vehicle and the BCI system
detects an approaching vehicle at the
same time, the following indications are
provided:
— The sonar system chime sounds
— The side indicator light on the side of the approaching vehicle flashes, and
— A yellow rectangular frame appears in the upper display.

Upper display
If an approaching vehicle or close object
behind the vehicle is detected when your
vehicle is backing up, a red frame
will
appear in the upper display and the system
will chime three times. Then, the brakes will
be applied momentarily. After the automatic
brake application, the driver must depress
the brake pedal to maintain brake pressure.
If the driver’s foot is on the accelerator
pedal, the system moves the accelerator
pedal upward before the braking is applied.
However, if you continue to accelerate, the
system will not engage the brakes.
The BCI system does not operate if the
object is very close to the bumper.

The BCI system can be turned off tempora-
rily by touching the BCI system key
on the
upper display. The indicator on the BCI
system key turns off.
When the shift lever is placed in the R
(Reverse) position again, the BCI system is
turned on.
HOW TO ENABLE/DISABLE THE
BCI SYSTEM
The BCI system can be turned off perma-
nently using the lower display.

.If you move the shift lever to N (Neutral)
position, the cruise control will be can-
celed.
To reset at a faster cruising speed, use one
of the following methods:
. Depress the accelerator pedal. When the
vehicle attains the desired speed, push
and release the COAST/SET switch.
. Push and hold the ACCELERATE/RE-
SUME switch. When the vehicle attains
the speed you desire, release the switch.
. Push, then quickly release the ACCEL-
ERATE/RESUME switch. Each time you
do this, the set speed will increase by
about 1 MPH (1.6 km/h).
To reset at a slower cruising speed, use one
of the following methods:
. Lightly tap the brake pedal. When the
vehicle attains the desired speed, push
the COAST/SET switch and release it.
. Push and hold the COAST/SET switch.
Release the switch when the vehicle
slows down to the desired speed.
. Push, then quickly release the COAST/
SET switch. Each time you do this, the
set speed will decrease by about 1 MPH
(1.6 km/h).
To resume the preset speed, push and
release the ACCELERATE/RESUME
switch. The vehicle will resume the last set
cruising speed when the vehicle speed is over 25 MPH (40 km/h).WARNING
Failure to follow the warnings and
instructions for proper use of the ICC
system could result in serious injury or
death.
.
ICC is not a collision avoidance or
warning device. For highway use only
and it is not intended for congested
areas or city driving. Failure to apply
the brakes could result in an accident.
. Always observe posted speed limits
and do not set the speed over them.
. Always drive carefully and atten-
tively when using either cruise con-
trol mode. Read and understand the
Owner’s Manual thoroughly before
using the cruise control. To avoid
serious injury or death, do not rely
on the system to prevent accidents or
to control the vehicle’s speed in
emergency situations. Do not use
cruise control except in appropriate
road and traffic conditions.
. In the conventional (fixed speed)
cruise control mode, a warning chime
will not sound to warn you if you are
too close to the vehicle ahead. Pay
special attention to the distance
between your vehicle and the vehicle
INTELLIGENT CRUISE CONTROL
(ICC) (if so equipped)

WAF0308X
System set display with vehicle ahead

System operation
The driver sets the desired vehicle speed
based on the road conditions. The ICC
system maintains the set vehicle speed,
similar to standard cruise control, as long
as no vehicle is detected in the lane ahead.
The ICC system displays the set speed.
Vehicle detected ahead:
When a vehicle is detected in the lane ahead,
the ICC system decelerates the vehicle by
controlling the throttle and applying thebrakes to match the speed of a slower
vehicle ahead. The system then controls the
vehicle speed based on the speed of the
vehicle ahead to maintain the driver selected
distance.
The stoplights of the vehicle come on when
braking is performed by the ICC system.
When the brake operates, a noise may be
heard and/or vibration may be felt. This is
not a malfunction.
When a vehicle ahead is detected, the
vehicle ahead detection indicator comes on.
The ICC system will also display the set
speed and selected distance.Vehicle ahead not detected:
When a vehicle is no longer detected ahead,
the ICC system gradually accelerates your
vehicle to resume the previously set vehicle
speed. The ICC system then maintains the
set speed.
When a vehicle is no longer detected the
vehicle ahead detection indicator turns off.
If a vehicle ahead appears during accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system
controls the distance to that vehicle.
When a vehicle is no longer detected under
approximately 15 MPH (24 km/h), the
system will be canceled.
