Description and Operation: Description: Notes

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. 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.)
6. Warning alarm

   If the vehicle equipped the SCC decelerates because a vehicle ahead decelerates or moves into your lane, the warning will operate.

   1. In case that the vehicle equipped with SCC is able to decelerate properly by the system - No warning
   2. In case that the vehicle equipped with SCC is not able to decelerate properly by the system - Indicator in the cluster will blink and the warning buzzer will sound. (The warning and deceleration by the system will go on until the brake pedal is applied.)
7. Accelerating by driver

   Even the vehicle is being decelerated by the SCC system, the vehicle can be accelerated by applying the accelerator pedal. If the vehicle is accelerated above the set speed, the indicator in the cluster will blink.

   NOTE:

   • Smart cruise control operating conditions
     • Vehicle speed at more than approximately 10km/h (6.2mph) or less than approximately 180km/h (111.8mph)
     • Transmission in D or Sports mode.
     • "ESP OFF" switch OFF
     • Parking brake released
     • "ON/OFF" switch ON (CRUISE indicator ON)

       Under the above conditions, activate the cruise system using the "SET/-" or "RES/+" switch.

     • Smart cruise control disabling conditions
   • "ON/OFF" switch OFF
   • "CANCEL" switch ON
   • Brake pedal applied
   • Vehicle speed at less than approximately 10km/h (6.2mph) when there is a vehicle ahead in the lane. (The warning buzzer will sound and indicator in the cluster will display.)
   • Vehicle speed at less than approximately 30km/h (18.6mph) when there is not a vehicle ahead in the lane. (The warning buzzer will sound and indicator in the cluster will display.)
   • Vehicle speed at more than approximately 180km/h (111.8mph)
   • Transmission in N or R
   • ESP/TCS/ABS operating (The warning buzzer will sound and indicator in the cluster will display.)
