I-BSI SYSTEM OPERATION
The I-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 (1)
illuminates.
If the turn signal is then activated, the sys-
tem chimes (twice) and the side indicator
light flashes. The side indicator light contin-
ues to flash until the detected vehicle
leaves the detection zone. The brightness
of the side indicator light is adjusted auto-
matically depending on the brightness of
the ambient light.
If the I-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 I-BSI system activates to
help return the vehicle back to the center of
the driving lane. The I-BSI system operates
regardless of turn signal usage.

SYSTEM TEMPORARILY
UNAVAILABLE
Under the following conditions, a chime will
sound, the following message will appear
in the vehicle information display and the
I-BSI system will be turned off automati-
cally. The I-BSI system will not be available
until the conditions no longer exist.
• “Not available Poor Road Conditions”
• When the VDC system (except TCS func-tion) or ABS operates. • “Currently not available”
• When the VDC system is turned off.
Action to take:
When the above conditions no longer exist,
push the ProPILOT Assist switch (models
with ProPILOT Assist) or the dynamic driver
assistance switch (models without ProPI-
LOT Assist) again to turn the I-BSI system
back on.
When radar blockage is detected, the I-BSI
system will be turned off automatically, a
chime will sound and the “Unavailable: Side
Radar Obstruction” warning message will
appear in the vehicle information display.
The I-BSI system is not available until the
conditions no longer exist. For additional
information, see “System maintenance”
(P. 5-56).
Action to take:
When the above conditions no longer exist,
turn the I-BSI system on again. If the “Un-
available: Side Radar Obstruction” warning
message appears even af ter the I-BSI sys-
tem is turned on again, stop the vehicle in a
safe location, place the vehicle in the P
(Park) position and turn the EV system off.
Check for and remove objects obscuring
the radar sensors on the rear bumper, and
restart the EV system.
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F (40°C)) and then the
I-BSI system is turned on, the I-BSI system
may be deactivated automatically. The
“Unavailable: High Cabin Temperature”
warning message will appear in the vehicle
information display.
Action to take:
When the interior temperature is reduced,
push the ProPILOT Assist switch (models
with ProPILOT Assist) or the dynamic driver
assistance switch (models without ProPI-
LOT Assist) again to turn the I-BSI system
back on.
SYSTEM MALFUNCTION
When the I-BSI system malfunctions, it will
be turned off automatically, a chime will
sound, and the “Not available System Mal-
function” warning message with the BSW
indicator (orange) will appear in the vehicle
information display.
Starting and driving5-55

NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC sensor detects objects on the
side of the vehicle or on the side of the
road. This may cause the ICC system to
decelerate or accelerate the vehicle. The
ICC sensor may detect these objects
when the vehicle is driven on winding
roads, narrow roads, hilly roads, or when
entering or exiting a curve. In these
cases you will have to manually control
the proper distance ahead of your
vehicle.
Also, the sensor sensitivity can be af-
fected by vehicle operation (steering
maneuver or driving position in the lane)
or traffic or vehicle condition (for ex-
ample, if a vehicle is being driven with
some damage).
Acceleration when passing
When the ICC system is engaged above 43
mph and following a slower vehicle (below
ICC set speed), and the turn signal is acti-
vated to the lef t, the ICC system will auto-
matically start to accelerate the vehicle to
help initiate passing on the lef t and will
begin to reduce the distance to the vehicle
directly ahead. Only the lef t side turn signaloperates this feature. As the driver steers
the vehicle and moves into the passing
lane, if no vehicle is detected ahead the ICC
system will continue to accelerate to the
ICC system set speed. If another vehicle is
detected ahead, then the vehicle will accel-
erate up to the following speed of that ve-
hicle. If the vehicle is not steered into the
lef t lane to pass, the acceleration will stop
af ter a short time and regain the set follow-
ing distance. Acceleration can be stopped
at any point by depressing the brake pedal
or the CANCEL switch on the steering
wheel.
WARNING
In order to reduce the risk of a collision
that may result in serious injury or
death, please be aware of the following:
• This function is only activated with
the lef t turn signal and will briefly ac-
celerate the vehicle even if a lane
change is not initiated. This can in-
clude non-passing situations such as
lef t side exits.
• Ensure that when passing another
vehicle, the adjacent lane is clear be-
fore initiating the pass. Sudden
changes in traffic may occur while
passing. –
Always manually steer or brake as
needed
– Never solely rely on the system
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically
canceled:
• When the vehicle ahead is not detected
and your vehicle is traveling below the
speed of 15 mph (24 km/h)
• When the system judges the vehicle is at a standstill
• When the shif t lever is not in the D (Drive) position or B mode
• When the parking brake system is applied
• When the VDC system is turned off
• When VDC operates
• When distance measurement becomes impaired due to adhesion of dirt or ob-
struction to the sensor
• When a wheel slips
• When the radar signal is temporarily interrupted
5-78Starting and driving

•In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Al-
ways stay alert and avoid using the
ICC system where not recommended
in this warning section.
The radar sensor will not detect the follow-
ing objects:
• Stationary and slow-moving vehicles
• Pedestrians or objects in the roadway
• Oncoming vehicles in the same lane
• Motorcycles traveling offset in the travel lane
The sensor generally detects the signals
returned from the vehicle ahead. Therefore,
if the sensor cannot detect the reflection
from the vehicle ahead, the ICC system
may not maintain the selected distance.
The following are some conditions in which
the sensor cannot properly detect a ve-
hicle ahead and the system may not oper-
ate properly:
• When snow or road spray from traveling vehicles reduces the sensor’s detection.
• When excessively heavy baggage is loaded in the rear seat or the cargo area
of your vehicle. The ICC system is designed to automati-
cally check the sensor’s operation within
the limitations of the system.
When the sensor is covered with dirt or is
obstructed, the system will automatically
be canceled. If the sensor is covered with
ice, a transparent or translucent vinyl bag,
etc., the ICC system may not detect them.
In these instances, the vehicle-to-vehicle
distance control mode may not cancel and
may not be able to maintain the selected
following distance from the vehicle ahead.
Be sure to check and clean the sensor
regularly.
The detection zone of the radar sensor is
limited. A vehicle ahead must be in the de-
tection zone for the vehicle-to-vehicle dis-
tance detection mode to maintain the se-
lected distance from the vehicle ahead.
A vehicle ahead may move outside of the
detection zone due to its position within
the same lane of travel. Motorcycles may
not be detected in the same lane ahead if
they are traveling offset from the center
line of the lane. A vehicle that is entering the
lane ahead may not be detected until the
vehicle has completely moved into the
lane.
If this occurs, the ICC system may warn
you by blinking the system indicator and
sounding the chime. The driver may
have to manually control the proper dis-
tance away from the vehicle traveling
ahead.
