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.

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).)

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.

PRECAUTIONS ON VEHICLE-TO-VE-
HICLE DISTANCE CONTROL MODE
The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the radar sensor
*Adetects a slower
moving vehicle ahead, the system will
reduce the vehicle speed so that your
vehicle follows the vehicle in front at the
selected distance.
The system automatically controls the
throttle and applies the brakes (up to
approximately 40% of vehicle braking power) if necessary.
The detection range of the sensor is
approximately 650 ft (200 m) ahead.
WARNING
.
This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’ s
responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
. The system is primarily intended for use
on straight, dry, open roads with light
traffic. It is not advisable to use the
system in city traffic or congested areas.
. This system will not adapt automatically
to road conditions. This system should
be used in evenly flowing traffic. Do not
use the system on roads with sharp
curves, or on icy roads, in heavy rain or
in fog.
The radar sensor will not detect under
most conditions:
.Stationary and slow moving vehicles
. Pedestrians or objects in the roadway .
Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
WARNING
. As there is a performance limit to the
distance control function, never rely
solely on the Intelligent Cruise Control
(ICC) system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visi-
bility in rain, fog, or other bad weather.
Decelerate the vehicle speed by depres-
sing the brake pedal, depending on the
distance to the vehicle ahead and the
surrounding circumstances in order to
maintain a safe distance between vehi-
cles.
. If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. The
system will cancel once it judges that
the vehicle has come to a standstill and
sound a warning chime. To prevent the
vehicle from moving, the driver must
depress the brake pedal.
. The system may not detect the vehicle in

System operation
WARNING
Normally when controlling the distance to a
vehicle ahead, this system automatically
accelerates or decelerates your vehicle
according to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is
required for a lane change. Depress the brake pedal when deceleration is required to
maintain a safe distance to the vehicle
ahead due to its sudden braking or if a
vehicle cuts in. Always stay alert when
using the ICC system.
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 the brakes 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. 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 acceler-
ates 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 accel-
eration to the set vehicle speed or any time
