Illustration 3: If the BSI system is on and your
vehicle is approaching a lane marker and a
vehicle is in the detection zone, the system
chimes a sound (three times), and the side
indicator light flashes. Then the BSI system
slightly applies the brakes on one side to help
return the vehicle back to the center of the
driving lane.NOTE:

Illustration 5: The side indicator light illumi-
nates if you overtake a vehicle and that ve-
hicle stays in the detection zone for approxi-
mately 3 seconds.
The radar sensors may not detect slower
moving vehicles if they are passed quickly.

Illustration 10: If the driver activates the turn
signal while another vehicle is in the detection
zone, then the side indicator light flashes and
a chime will sound twice.
NOTE:
If the driver activates the turn signal before
a vehicle enters the detection zone, the side
indicator light will flash but no chime will
sound when another vehicle is detected.Illustration 11: If the BSI system is on and

NOTE:
∙ Illustration 12: The BSI system will not
operate if your vehicle is on a lane marker
when another vehicle enters the detec-
tion zone. In this case, only the BSW sys-
tem operates.
∙ BSI braking will not operate or will stop
operating and only a warning chime will
sound under the following conditions:
– When the brake pedal is depressed.
– When the vehicle is accelerated dur-
ing BSI system operation.

BCI SYSTEM OPERATION
When the shift position is in R (Reverse) and
the vehicle speed is less than approximately
5 mph ( 8 km/h), the BCI system operates.
If the radar detects a vehicle approaching
from the side or the sonar detects close sta-
tionary objects behind the vehicle, the system
gives visual and audible warnings. If the driver
does not apply the brakes, the system auto-
matically 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 pressure. If the driver’s foot is on the
accelerator pedal, the system pushes the ac-
celerator upward before applying the brake.
If you continue to press the accelerator, the
system will not engage the brake.
When the shift lever is placed in the R (Re-
verse) position, the
key appears in the
upper display. The BCI system can be turned
off temporarily by touching the BCI system
key on the upper display.

If the radar detects an approaching vehicle
from the side, the system chimes a sound
(single beep), the side indicator light on the
side of the approaching vehicle flashes and a
yellow rectangular frame appears in the dis-
play
A.NOTE:
∙ In the case of several vehicles approach-
ing in a row (Illustration 1) or in the op-
posite direction (Illustration 2), a chime
may not be sounded by 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 ap-
proaching vehicle at the same time the fol-
lowing indicators 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 display
If an approaching vehicle or object behind the
vehicle is detected when your vehicle is back-
ing up, a red frame will appear in the display
Aand 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 main-
tain brake pressure.

If the driver’s foot is on the accelerator pedal,
the system moves the accelerator pedal up-
ward before the braking is applied. However,
if you continue to accelerate, the system will
not engage the brakes.The system does not operate if the object is
very close to the bumper.

If the radar sensorBdetects a slower mov-
ing 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 ap-
proximately 40% of vehicle braking power) if
necessary.
The detection range of the sensor is approxi-
mately 650 ft (200 m) ahead.

A warning chime will sound and a message
will pop up:∙ When the VDC system is off (To use the ICC system, turn on the VDC system.
Push the ICC switch to turn off the ICC
system and reset the ICC switch by push-
ing the ICC switch again.)
For additional information about the
VDC system, refer to “Vehicle Dynamic
Control (VDC) system” in this section.
∙ When VDC is operating
∙ When a wheel is slipping (To use the ICC system, make sure the wheels are no lon-
ger slipping.)
1System set display with vehicle ahead
2System set display without vehicle ahead
The driver sets the desired vehicle speed
based on the road conditions. The ICC sys-
tem 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 dis-
tance.
NOTE:
∙ The stop lights 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 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 con-
trols the distance to that vehicle.

LIMITATIONS
WARNING
Listed below are the system limitations for
the ICC system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
∙ The ICC system is primarily intended foruse on straight, dry, open roads with light
traffic. It is not advisable to use the ICC
system in city traffic or congested areas.
∙ The ICC system will not adapt automati- cally 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. ∙ As there is a performance limit to the dis-
tance control function, never rely solely
on the ICC system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visibil-
ity in rain, fog, or other bad weather. De-
celerate the vehicle speed by depressing
the brake pedal, depending on the dis-
tance to the vehicle ahead and the sur-
rounding circumstances in order to main-
tain a safe distance between vehicles.
∙ 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.
∙ Always pay attention to the operation of the vehicle and be ready to manually con-
trol the proper following distance. The
ICC system may not be able to maintain
the selected distance between vehicles
(following distance) or selected vehicle
speed under some circumstances. ∙ The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the ICC system under the following
conditions:
– On roads where the traffic is heavy or there are sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the bumper around the distance sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it diffi- cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources
∙ Do not use the ICC system if you are tow- ing a trailer. The system may not detect a
vehicle ahead.
