9.21.8.7. ICC system limitations
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 ICC system is primarily intended for use on straight, dry, open roads with light traffic. It is not advisable to use the ICC system in city traffic or congested areas.
The ICC system will not adapt automatically 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 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.
When the ICC system automatically brings the vehicle to a stop, your vehicle can automatically accelerate if the vehicle is stopped for less than approximately 3 seconds. Be prepared to stop your vehicle if necessary.
Always check surroundings before restarting the vehicle.
Always pay attention to the operation of the vehicle and be ready to manually control the proper following distance. The ICC system may not be able to maintain the selected distance between vehicles (following distance) or selected vehicle speed under some circumstances.
The ICC system does not detect the following objects:
Stationary or slow moving vehicles (when your vehicle is approaching them)
Pedestrians or objects in the roadway
Oncoming vehicles in the same lane
Motorcycles travelling offset in the travel lane
The ICC system may not detect a vehicle ahead in certain road, weather or driving conditions. To avoid accidents, never use the ICC system under the following conditions:
On roads with heavy, high-speed traffic or sharp curves
On slippery road surfaces such as on ice or snow, etc.
On a bumpy road surface, such as an uneven dirt road
On steep downhill roads (the vehicle may go beyond the vehicle set speed and frequent braking may result in overheating the brakes)
On repeated uphill and downhill roads
During bad weather (rain, fog, snow, etc.)
When the sensor detection is reduced (conditions such as rain, snow, fog, dust storms, sandstorms, and road spray from other vehicles)
When dirt, ice, snow or other material adhere to the radar sensor area
When traffic conditions make it difficult to keep a proper distance between vehicles because of frequent acceleration or deceleration
When a complicated-shaped vehicle such as a car carrier trailer or flatbed truck/trailer is near the vehicle ahead
When there is interference by other radar sources
When excessively heavy baggage is loaded in the rear seat or cargo area of your vehicle
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. Always stay alert and avoid using the ICC system where not recommended in this warning section.
The ICC system also uses a multi-sensing front camera. The following are some conditions in which the camera may not properly detect a vehicle and detection of a vehicle ahead may be delayed:
Poor visibility (conditions such as rain, snow, fog, dust storms, sandstorms, and road spray from other vehicles)
The camera area of the windscreen is fogged up or covered with dirt, water drops, ice, snow, etc.
Strong light (for example, sunlight or high beams from oncoming vehicles) enters the front camera
Strong light causes the area around the pedestrian to be cast in a shadow, making it difficult to see
A sudden change in brightness occurs (for example, when the vehicle enters or exits a tunnel or shaded area or lightning flashes)
The ICC system is designed to automatically check the radar sensor’s operation within the limitations of the system
The detection zone of the radar sensor is limited. A vehicle ahead must be in the detection zone for the ICC system 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 travelling offset from the centre line 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 the vehicle travelling ahead.
When driving on some roads, such as winding, hilly, curved, narrow roads, or roads which are under construction, the radar sensor may detect vehicles in a different lane, or may temporarily not detect a vehicle travelling ahead. This may cause the ICC system to decelerate or accelerate the vehicle.
The detection of vehicles may also be affected by vehicle operation (steering manoeuvre or travelling position in the lane, etc.) or vehicle condition.
If this occurs, the ICC system may warn you by blinking the system indicator and sounding the chime unexpectedly. You will have to manually control the proper distance away from the vehicle travelling ahead.
