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.

JVS1154X
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.5-72). 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.

Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that
vehicle or if another vehicle cuts in, the
system warns the driver with the chime and
ICC system display. Decelerate by depres-
sing the brake pedal to maintain a safe
vehicle distance if:
.The chime sounds.
. The vehicle ahead detection and set
distance indicator blink.
The warning chime may not sound in some
cases when there is a short distance be-
tween vehicles. Some examples are:
. When the vehicles are traveling at the
same speed and the distance between
vehicles is not changing
. When the vehicle ahead is traveling
faster and the distance between vehicles
is increasing
. When a vehicle cuts in near your vehicle
The warning chime will not sound when:
. Your vehicle approaches other vehicles
that are parked or moving slowly.
. The accelerator pedal is depressed, over-
riding the system.
NOTE:
The approach warning chime may sound
and the system display may blink when the radar 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 radar 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 affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or
vehicle condition (for example, if a vehicle is
being driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed.
.
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
standstill
. When the shift lever is not in the D (Drive)
or manual shift mode
. When the parking brake is applied
. When the SNOW mode switch is pushed
on. .
When the 4WD shift switch is in the 4H
or 4L position (for 4WD models)
. When the VDC system is turned off
. When the VDC (including the traction
control system) operates
. When distance measurement becomes
impaired due to adhesion of dirt or
obstruction to the sensor
. When a wheel slips
. When the radar signal is temporarily
interrupted
Vehicle-to-vehicle distance control
mode limitations
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
. 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 con-
gested areas.
. This 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
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absent-minded driving, or over-
come poor visibility in rain, fog, or
other bad weather. Decelerate the
vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing 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 opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The vehicle-to-vehicle
distance control mode of the ICC
system may not be able to maintain
the selected distance between vehi- cles (following distance) or selected
vehicle speed under some circum-
stances.
. Normally when controlling the dis-
tance to a vehicle ahead, this system
automatically accelerates or decele-
rates your vehicle according to the
speed of the vehicle ahead. Depress
the accelerator to properly accelerate
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 system may not detect the
vehicle in front of you in certain road
or weather conditions. To avoid ac-
cidents, 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 system sensor — On steep downhill roads (the
vehicle may go beyond the set
vehicle speed and frequent brak-
ing may result in overheating the
brakes)
— On repeated uphill and downhill roads
— When traffic conditions make it difficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration
. Do not use the ICC system if you are
towing a trailer. The system may not
detect a vehicle ahead.
. In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. You
may need to control the distance
from other vehicles using the accel-
erator pedal. Always stay alert and
avoid using the ICC system when it is
not recommended in this 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
