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 vehicles (following dis- tance) 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. Therefore, 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 luggage room of your vehicle

The ICC system is designed to automati- cally 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 dis- tance 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. How- ever, 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 decele- rates, the distance between vehicles may become closer because the ICC system cannot decelerate the vehicle quickly en- ough. If this occurs, the ICC system will sound a warning chime and blink the system display to notify the driver to take necessary action.
