BCI SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the BCI system. Failure to operatethe vehicle in accordance with these
system limitations could result in serious
injury or death.
.
Always check your surroundings and
turn to check what is behind you
before backing up. .
The radar sensors detect approach-
ing (moving) vehicles. The radar sen-
sors cannot detect every object such
as:
— Pedestrians, bicycles, animals or child operated toy vehicles
— A vehicle that is passing at speeds greater than approximately 15
MPH (24 km/h)
. The radar sensors may not detect
approaching vehicles in certain situa-
tions:
— Illustration a. When a vehicle parked next to you obstructs the
beam of the radar sensor.
— Illustration b. When the vehicle is parked in an angled parking space.
— Illustration c. When the vehicle is parked on inclined ground.
— Illustration d. When an approach- ing vehicle turns into your vehi-
cle’s parking lot aisle.
— Illustration e. When the angle formed by your vehicle and ap-
proaching vehicle is small.
. The following conditions may reduce
the ability of the radar sensors to
detect other vehicles:

— Severe weather
— Road spray
— Ice/frost/dirt build up on thevehicle
. Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint near
the radar sensors. These conditions
may reduce the ability of the radar
sensors to detect other vehicles.
. The sonar sensors detect stationary
objects behind the vehicle. The sonar
sensor may not detect:
— Small or moving objects
— Wedge-shaped objects
— Object close to the bumper (less than approximately 1 ft (30 cm))
— Thin objects such as rope, wire and chain, etc.
. The brake engagement by the BCI
system is not as effective on a slope
as it is on flat ground. When on a
steep slope the system may not
function properly.
. Do not use the BCI system under the
following conditions because the sys-
tem may not function properly. — 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.
. Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound,
and it may not be heard.

Cruise indicator
The cruise indicator and the set vehicle
speed are displayed in the vehicle informa-
tion display. The cruise indicator indicates
the status of the cruise control system by the
color.
The cruise control allows driving at a speed
between 25 to 90 MPH (40 to 144 km/h)
without keeping your foot on the accelerator
pedal.
To turn on the cruise control, push the
MAIN switch on. The cruise indicator (white)
will come on.
To set cruising speed, accelerate your
vehicle to the desired speed, push the SET/
COAST (-) switch and release it. (The cruise
indicator (green) will illuminate.) Take your foot off the accelerator pedal. Your vehicle
will maintain the set speed.
.
To pass another vehicle, depress the
accelerator pedal. When you release the
pedal, the vehicle will return to the
previously set speed.
. The vehicle may not maintain the set
speed on winding or hilly roads. If this
happens, drive without the cruise con-
trol.
To cancel the preset speed, follow any of
these methods:
1. Push the CANCEL switch.
2. Tap the brake pedal.
3. Turn the MAIN switch off.
After any of the above operations is per-
formed, the color of the cruise indicator will
change from green to white.
. If you depress the brake pedal while
pushing the RESUME/ACCELERATE
(+) or SET/COAST (-) switch and reset
at the cruising speed, the cruise control
will disengage. Turn the MAIN switch off
once and then turn it on again.
. The cruise control will automatically
cancel if the vehicle slows more than 8
MPH (13 km/h) below the set speed.
. 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 SET/COAST (-) switch.
. Push and hold the RESUME/ACCELER-
ATE (+) switch. When the vehicle attains
the speed you desire, release the switch.
. Push, then quickly release the RESUME/
ACCELERATE (+) 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 SET/COAST (-) switch and release it.
. Push and hold the SET/COAST (-)
switch. Release the switch when the
vehicle slows down to the desired speed.
. Push, then quickly release the SET/
COAST (-) 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 RESUME/ACCELERATE (+)
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 ahead of you or a collision could
occur.
The ICC system maintains a selected dis-
tance from the vehicle in front of you within
the speed range of 0 to 90 MPH (0 to 144
km/h) up to the set speed. The set speed can
be selected by the driver between 20 to 90
MPH (32 to 144 km/h).
The vehicle travels at a set speed when the
road ahead is clear.
The ICC system can be set to one of two
cruise control modes.
. Vehicle-to-vehicle distance control
mode:
For maintaining a selected distance
between your vehicle and the vehicle in
front of you up to the preset speed.
. Conventional (fixed speed) cruise control
mode:
For cruising at a preset speed.

VEHICLE-TO-VEHICLE DIS-
TANCE CONTROL MODE
In the vehicle-to-vehicle distance control
mode, the ICC system automatically main-
tains a selected distance from the vehicle
traveling in front of you according to that
vehicle’s speed (up to the set speed), or at
the set speed when the road ahead is clear.

JVS1123X
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
detects 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 throt-
tle and applies the brakes (up to approxi-
mately 40% of vehicle braking power) if
necessary.
The detection range of the sensor is approxi-
mately 650 ft (200 m) ahead.
Vehicle-to-vehicle distance control
mode operation
The vehicle-to-vehicle distance control
mode is designed to maintain a selected
distance and reduce the speed to match the
slower vehicle ahead; the system will de-
celerate the vehicle as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill. However, the ICC
system can only apply up to approximately
40% of the vehicle’s total braking power.
This system should only be used when traffic
conditions allow vehicle speeds to remain
fairly constant or when vehicle speeds
change gradually. If a vehicle moves into
the traveling lane ahead or if a vehicle
traveling ahead rapidly decelerates, the
distance between vehicles may become
closer because the ICC system cannot
decelerate the vehicle quickly enough. If this
occurs, the ICC system will sound a warning
chime and blink the system display to notify
the driver to take necessary action.
The system will cancel and a warning chime
will sound if the speed is below approxi-
mately 15 MPH (24 km/h) and a vehicle is
not detected ahead. The system will also
disengage when the vehicle goes above the
maximum set speed.
See “Approach warning” (P.5-83). The following items are controlled in the
vehicle-to-vehicle distance control mode:
.
When there are no vehicles traveling
ahead, the vehicle-to-vehicle distance
control mode maintains the speed set
by the driver. The set speed range is
between approximately 20 and 90 MPH
(32 and 144 km/h).
. When there is a vehicle traveling ahead,
the vehicle-to-vehicle distance control
mode adjusts the speed to maintain the
distance, selected by driver, from the
vehicle ahead. The adjusting speed range
is up to the set speed. 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 a standstill with
a warning chime.
. When the vehicle traveling ahead has
moved out from its lane of travel, the
vehicle-to-vehicle distance control mode
accelerates and maintains vehicle speed
up to the set speed.
The ICC system does not control vehicle
speed or warn you when you approach
stationary and slow moving vehicles. You
must pay attention to vehicle operation to
maintain proper distance from vehicles
ahead when approaching toll gates or traffic
congestion.

SSD0254
When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system will adjust the speed
to maintain the distance, selected by the
driver, from the vehicle ahead. If the vehicle
ahead changes lanes or exits the freeway,
the ICC system will accelerate and maintain
the speed up to the set speed. Pay attention
to the driving operation to maintain control
of the vehicle as it accelerates to the set
speed.
The vehicle may not maintain the set speed
on winding or hilly roads. If this occurs, you
will have to manually control the vehicle
speed.
Normally when controlling the distance to avehicle ahead, this system automatically
accelerates or decelerates your vehicle ac-
cording 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.
JVS0836X
Vehicle-to-vehicle distance control
mode switches
The system is operated by a MAIN switch
and four control switches, all mounted on
the steering wheel.
1. RESUME/ACCELERATE (+) switch:
Resumes set speed or increases speed
incrementally.
2. SET/COAST (-) switch: Sets desired cruise speed, reduces speed
incrementally.
3. CANCEL switch: Deactivates the system without erasing
the set speed.
