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
. 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
Starting and driving5-75

5-76Starting and driving
the sensor cannot detect the signals:
.When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
. When excessively heavy baggage is
loaded in the rear seat or the luggage
area of your vehicle
. When your vehicle is towing a trailer, etc.
The ICC system is designed to automatically
check the sensor’s operation within the
limitation 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.
SSD0252
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
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 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 distance away from
vehicle traveling ahead.

DCA SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
of the DCA system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
.This system will not adapt automati-
cally to road conditions. Do not use
the system on roads with sharp
curves, or on icy roads, in heavy rain
or in fog.
. The DCA system will not apply brake
control while the driver’s foot is on
the accelerator pedal.
. As there is a performance limit to the
distance control function, never rely
solely on the DCA system. This sys-
tem does not correct careless, inat-
tentive or absent-minded driving, or
overcome 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. .
The system may not detect the

— If dirt, ice, snow or other material is covering the radar sensor area.
— Interference by other radar sources.
— The camera area of windshield is fogged up, or covered with dirt,
water drops, ice, snow, etc.
— Strong light (for example, sun- light or high beams from oncom-
ing vehicles) enters the front
camera. Strong light causes the
area around the pedestrian to be
cast in a shadow, making it diffi-
cult to see.
— A sudden change in brightness occurs. (For example, when the
vehicle enters or exits a tunnel or a
shaded area or lightning flashes.)
— The poor contrast of a person to the background, such as having
clothing color or pattern which is
similar to the background.
— The pedestrian’s profile is par- tially obscured or unidentifiable
due to the pedestrian transport-
ing luggage, wearing bulky or very
loose-fitting clothing or acces- sories.
— When towing a trailer or other vehicle.
. The system performance may de-
grade in the following conditions:
— The vehicle is driven on a slippery road.
— The vehicle is driven on a slope.
— Excessively heavy baggage is loaded in the rear seat or the
luggage area of your vehicle.
. The system is designed to automati-
cally check the sensor (radar and
camera)’s functionality, within cer-
tain limitations. The system may not
detect blockage of sensor areas cov-
ered by ice, snow or stickers, for
example. In these cases, the system
may not be able to warn the driver
