PRECAUTIONS FOR VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
ICC 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 safe ly 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 condi tions. 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.
The ICC sensor will not detect under most conditions.
- Stationary and slow moving vehicles.
- Pedestrians or objects in the roadway.
- Oncoming vehicles in the some lane.
- Motorcycles traveling offset in the travel lane.
As there is a performance limit to the distance contro l function, never rely solely on the ICC system. This
system does not correct careless, inattentive 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 surrounding circumstances in order to maintain a safe distance
between vehicles.
If the vehicle ahead comes to a stop, the vehicle decelerat es to a standstill within the limitations of the sys-
tem. 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 movi ng, the driver must depress the brake pedal.
The system may not detect the vehicle in front of the dr iver in certain road or weather conditions. To avoid
accidents, never use the ICC syst em 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.
- On off-road surfaces such as on sand or rock, etc.
- During bad weather (rain, fog, snow, etc.)
- When the windshield wipers are operating at high speed. The ICC system may cancel when the wipers are
set to the AUTO position.
- When strong light (for example, at sunrise or sunset ) is directly shining on the front of the vehicle.
- 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 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.
- When towing a trailer or other vehicle
In some road or traffic conditions, a vehicle or object can unexpectedly come into the sensor detection zone
and cause automatic braking. The driver may need to c ontrol the distance from other vehicles using the
accelerator pedal. Always stay alert and avoid using t he ICC system when it is not recommended in this sec-
tion.
The vehicle-to-vehicle distance control mode uses a sensor located on the front of the vehicle to detect vehi-
cles traveling ahead. The sensor generally detects t he signals returned from the reflectors on a vehicle
ahead. Therefore, if the sensor c annot detect the reflector on the v ehicle 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) fr om vehicles reduces the sensor's visibility.
- When excessively heavy baggage is loaded in the rear seat or the luggage room of own vehicle.
- When the vehicle is towing a trailer, etc.
The ICC system is designed to automatic ally check the sensor's operation within the limitation of the system.
When the sensor is covered with dirt or is obstruct ed, the system will automatically be canceled. If the sen-
sor 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 main-
tain the selected following distance from the vehicle ahead. Be sure to check and clean the sensor regularly.

WHEN THE ON BOARD SELF-DIAGNOSIS DOES NOT START
If the on board self-diagnosis does not start, check the following items.
HOW TO ERASE ON BOARD SELF-DIAGNOSIS
1. Turn the ignition switch OFF.
2. Start the engine, and then start the on board self-diagnosis.
3. Press the CANCEL switch 5 times, and then press the DIS-
TANCE switch 5 times under the condition that the on board
self-diagnosis starts.
NOTE:
Complete the operation within 10 seconds after pressing the
CANCEL switch first.
If the operation is not completed within 10 seconds, repeat the procedure from step 1.
4. DTC 55 is displayed after erasing. NOTE:
DTCs for existing malfunction can not be erased.
5. Turn ignition switch OFF, and finish the diagnosis.
