again to turn the system back on and select the
desired cruise control mode. VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE In the vehicle-to-vehicle distance control mode,
the Intelligent Cruise Control (ICC) system auto-
matically maintains 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.
With ICC, the driver can maintain the same
speed as other vehicles without the constant
need to adjust the set speed as you would with
a normal cruise control system. SSD0604

PRECAUTIONS ON VEHICLE-TO-
VEHICLE DISTANCE CONTROL MODE The system is intended to enhance the opera-
tion of the vehicle when following a vehicle
traveling in the same lane and direction.
If the distance sensor
 A
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 throttle
and applies the brakes (up to 25% of vehicle
braking power) if necessary. The detection range of the sensor is approxi-
mately 390 ft (120 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 sys-
tem on roads with sharp curves, or on icy
roads, in heavy rain or in fog.
The distance 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
laneSedan SSD0926

This system will not automatically brake the ve-
hicle to a stop.
WARNING● As there is a performance limit to the dis-
tance control function, never rely solely on
the Intelligent Cruise Control system. This
system does not correct careless, inatten-
tive or absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by de-
pressing the brake pedal, depending on the
distance to the vehicle ahead and the sur-
rounding circumstances in order to maintain
a safe distance between vehicles.
● Although the brake operation is controlled
by the system, the system does not auto-
matically stop the vehicle. If the vehicle
speed falls below approximately 20 MPH (32
km/h), the Intelligent Cruise Control system
is automatically canceled and a warning
chime sounds. (The brake control is also
canceled.)
● The system may not detect the vehicle in
front of you in certain road or weather condi-
tions. To avoid accidents, never use the In-
telligent Cruise Control 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 the windshield wiper is operated at
the low speed (LO) or high speed (HI) po-
sition, the Intelligent Cruise Control sys-
tem is automatically canceled.
– When strong light (for example, at sun-
rise or sunset) is directly shining on the
front of the vehicle
– When rain, snow or dirt adhere to the sys-
tem sensor
– On steep downhill roads (the vehicle may
go beyond the set vehicle speed and fre-
quent braking 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 frequent acceleration or
deceleration ● 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 dis-
tance from other vehicles using the accelera-
tor pedal. Always stay alert and avoid using
the ICC system when it is not recommended
in this section.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION Always pay attention to the operation of the
vehicle and be ready to manually control the
proper following distance. The vehicle-to-
vehicle distance control mode of the Intelligent
Cruise Control (ICC) system may not be able to
maintain the selected distance between ve-
hicles (following distance) or selected vehicle
speed under some circumstances. The vehicle-to-vehicle distance control mode
uses a sensor
 A
located on the front of the
vehicle to detect vehicles traveling ahead. The
sensor generally detects the signals returned
from the reflectors on a vehicle ahead. There-
fore, if the sensor cannot detect the reflector on
the vehicle ahead, the ICC system may not
maintain the selected distance.
The following are some conditions in which the
sensor cannot detect the signals:
● When the reflector of the vehicle ahead is
positioned high on the vehicle (trailer, etc.)
● When the reflector on the vehicle ahead is
missing, damaged or covered
● When the reflector of the vehicle ahead is
covered with dirt, snow and road spray
● When the snow or road spray from traveling
vehicles reduces the sensor’s visibility
● When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
visibility
● When excessively heavy baggage is loaded
in the rear seat or the trunk of your vehicleSedan SSD0926

The ICC system is designed to automatically
check the sensor’s operation within the limita-
tions of the system. When the sensor is covered
with dirt or obstructs, the system will automati-
cally 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 con-
trol 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 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 decelerate the vehicle as
necessary. However, the ICC system can only
apply up to 25% of the vehicles total braking
power. This system should only be used when
traffic conditions allow vehicle speeds to re-
main 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 be-
tween 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 falls below approximately 20
MPH (32 km/h). The system will also disengage
below the 20 MPH (32 km/h) cut-off speed or
over the maximum set speed.
See “Approach warning” later in this section.
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
25 and 90 MPH (40 and 144 km/h).
● When there is a vehicle traveling ahead, the
vehicle-to-vehicle distance control mode ad-
justs the speed to maintain the distance,
selected by driver, from the vehicle ahead.
The adjusting speed range is between ap-
proximately 20 MPH (32 km/h) and up to the
set speed.
● 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.

The detection zone of the ICC sensor is limited.
A vehicle ahead must be in the detection zone
for the vehicle-to-vehicle distance detection
mode to maintain the selected distance from
the vehicle ahead.
A vehicle ahead may move outside of the de-
tection 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 centerline 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 vehicle traveling ahead. SSD0252

When driving on some roads, such as winding,
hilly, curved, narrow roads, or roads which are
under construction, the ICC sensor may detect
vehicles in a different lane, or may temporarily
not detect a vehicle traveling ahead. This may
cause the ICC system to decelerate or acceler-
ate the vehicle.
The detection of vehicles may also be affected
by vehicle operation (steering maneuver or trav-
eling position in the lane, etc.) or vehicle con-
dition. If this occurs, the ICC system may warn
you by blinking the system indicator and sound-
ing the chime unexpectedly. You will have to
manually control the proper distance away from
the vehicle traveling ahead. When driving on the freeway at a set speed and
approaching a slower traveling vehicle ahead,
the ICC will adjust the speed to maintain the
distance, selected by the driver, from the ve-
hicle ahead. If the vehicle ahead changes lanes
or exits the freeway, the ICC system will accel-
erate 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. SSD0253 SSD0254
