Description & Operation: Description: Notes

WARNING: This page is about a different variant/trim than selected.

The smart cruise control system allows a driver to program the vehicle to control the speed and following distance detecting the vehicle ahead without depressing the brake pedal and the accelerator pedal.

  1. Cruise speed control: The vehicle maintains the selected speed if there are not vehicles ahead.
  2. Retardation control: The vehicle decelerates if a vehicle ahead is detected.
  3. Following distance control: The vehicle maintains the selected following distance.
  4. Acceleration control: The vehicle accelerates to the selected speed if a vehicle ahead is not detected.
  5. Congested area control: In traffic, your vehicle will stop if the vehicle ahead of you stops. Also, if the vehicle ahead of you starts moving, your vehicle will start as well. However, if the vehicle stops for more than 3 seconds, you must depress the accelerator pedal or push the RES+ switch to start driving.

  6. Control on curves
    1. The sensor may not detect a vehicle ahead or may detect a vehicle on other lanes because the detection range of the sensor is limited.
    2. On curves, if the vehicle equipped the SCC is driving at high speed, the vehicle can slip outside. Therefore reduce the speed on curves even there is not a vehicle ahead. (There is no brake control by SCC.)
    3. While the vehicle follows a vehicle ahead on straight road, if the vehicle ahead enters on curve, the vehicle equipped the SCC may accelerate to follow the vehicle ahead.
    4. On curves, if a vehicle ahead followed is out of range, the vehicle does not accelerate to the set speed and maintain the following speed to prevent from accelerating and decelerating repeatedly. (If the vehicle equipped the SCC changes the lane or apply the accelerator pedal, the vehicle will accelerate.)
  7. Accelerating by driver

    Even the vehicle is being decelerated by the SCC system, the vehicle can be accelerated by applying the accelerator pedal. When the SCC system on and driver presses the accelerator pedal, the LCD display in the cluster will blink.

      • An accelerator pedal applied for more than 300 sec
      • "ESP OFF" switch ON (ESP OFF indicator ON)
      • Parking brake applied
      • System failure (The warning indicator ON)
      • Crack, damage or wrong installation of smart cruise control unit cover (The warning indicator ON)
      • Yawrate sensor offset compensation incomplete
  8. Function of cruise control

    The driver may choose to only use the cruise control mode (speed control function) by doing as follows:

    When the Smart Cruise Control system is on (SCC Standby mode), push the distance to distance switch for more than 2 seconds. "Smart cruise control (SCC) mode" and "Cruise control (CC) mode" can be selected. The speed control of the cruise control mode is the same as that of the smart cruise control mode.

    When using the cruise control mode, the driver must manually access the distance to other vehicles as the system will not automatically brake to slow down for other vehicles.
