Description And Operation: Description: Notes

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

Cruise speed control: The vehicle maintains the selected speed if there are no vehicles ahead.
Retardation control: The vehicle decelerates if a vehicle ahead is detected.
Following distance control: The vehicle maintains the selected following distance.
Acceleration control: The vehicle accelerates to the selected speed if a vehicle ahead is not detected.

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 with the ASCC is driving at high speed, the vehicle can slip outside. Therefore reduce the speed on curves even if there is no vehicle ahead. (There is no brake control by ASCC.)
3. If a vehicle ahead enters on curve while following a vehicle on a straight road, the vehicle equipped with the ASCC may accelerate to keep the following distance.
Warning alarm
If the vehicle equipped the ASCC decelerates because a vehicle ahead decelerates or moves into your lane, the warning will operate.
1. In case that the vehicle equipped with ASCC is able to decelerate properly by the system - No warning
2. In case that the vehicle equipped with ASCC is not able to decelerate properly by the system
  - LCD Display 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.)
3. If the vehicle ahead (vehicle speed: less than 30km/h) disappears to the next lane while controlling following distance, the warning chime will sound and a message will appear. Adjust your vehicle speed for vehicles or objects that can suddenly appear in front of you.
Accelerating by driver
Even when the vehicle is being decelerated by the SCC system, the vehicle can be accelerated by applying the accelerator pedal. When the SCC system is on and driver depresses the accelerator pedal, the LCD display in the cluster will blink.

  - Transmission in N or P or R
  - ESP/TCS/ABS operating
  - An accelerator pedal applied for more than 300 sec
  - ESP OFF" switch ON (ESP OFF indicator ON)
  - Parking brake applied

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 (ASCC Standby mode), push the distance to distance switch for more than 2 seconds. "Smart cruise control (ASCC) 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.
