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 luggage room of your vehicle 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. 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 and if the vehicle ahead comes to a stop, the vehicle decelerates to a standstill. 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 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 approximately 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" 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 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-tovehicle distance control mode accelerates and maintains vehicle speed up to the set speed. 5-32 Starting and driving
