Kia Rio: Forward Collision-Avoidance Assist (FCA) system (Radar type) / Brake operation

  • In an emergency situation, the braking system enters in ready status for prompt reaction upon the driver depressing the brake pedal.
  • FCA system provides additional braking power for optimum braking performance when the driver depresses the brake pedal.
  • The braking control is automatically deactivated when the driver sharply depresses the accelerator pedal, or when the driver abruptly turns the steering wheel.
  • The braking control is automatically canceled when risk factors disappear.

CAUTION

The driver should always exercise caution when operating the vehicle, even though there is no warning message or warning alarm.

WARNING

FCA system braking control cannot completely stop the vehicle nor avoid all collisions. The driver should hold the responsibility to drive safely and control the vehicle.

WARNING

FCA system logic operates within certain parameters, such as the distance from the vehicle ahead, the speed of the vehicle ahead, and the driver's vehicle speed. Certain conditions such as inclement weather, road conditions, and systems limitations may affect the operation of the FCA system.

WARNING

Never deliberately drive dangerously to activate the system.

    FCA system produces warning messages, warning alarms, and emergency braking based on the level of risk of a frontal collision, such as when a vehicle ahead suddenly brakes, or when there is no following distance from the vehicle in front.

    In order for FCA system to operate properly, always make sure the sensor or sensor cover is clean and free of dirt, snow, and debris. Dirt, snow, or foreign substances on the lens may adversely affect the sensing performance of the sensor.
