If your vehicle comes closer to the vehicle ahead due to rapid deceleration of that vehicle or if another vehicle cuts in, the system warns the driver with the chime and ICC system display. Decelerate by depressing the brake pedal to maintain a safe vehicle distance if: . The chime sounds.

• The vehicle ahead detection and set distance indicator blink.

The warning chime may not sound in some cases when there is a short distance between vehicles. Some examples are: . When the vehicles are traveling at the same speed and the distance between vehicles is not changing.

• When the vehicle ahead is traveling faster and the distance between vehicles is increasing.

• When a vehicle cuts in near your vehicle The warning chime will not sound when: . Your vehicle approaches other vehicles that are parked or moving slowly.

• The accelerator pedal is depressed, overriding the system.

NOTE:
The approach warning chime may sound and the system display may blink when the ICC sensor detects some reflectors A which are fitted on vehicles in other lanes or on the side of the road. This may cause the ICC system to decelerate or accelerate the vehicle. The ICC sensor may detect these reflectors when the vehicle is driven on winding roads, hilly roads or when entering or exiting a curve. The ICC sensor may also detect reflectors on narrow roads or in road construction zones. In these cases you will have to manually control the proper distance ahead of your vehicle.

Also, the sensor sensitivity can be affected by vehicle operation (steering maneuver or driving position in the lane) or traffic or vehicle condition (for example, if a vehicle is being driven with some damage).
