Operation Description

Quickly push (less than 1.5 seconds) and release the MAIN switch ON.

The MAIN switch indicator, set distance indicator, own vehicle indicator, and set vehicle speed indicator come on and ICC system is set to a standby state.

ADAS control unit performs the control as per the following:

Constant speed	Comparing the set vehicle speed with the current vehicle speed, transmit the command to ECM via CAN communication to reach the set vehicle speed, and controls the electric throttle control actuator.
Deceleration	When a vehicle ahead (slower than driver set vehicle speed) appears or when a vehicle ahead slows down, the system controls the electric throttle control actuator into the close direction and decelerates the vehicle. If greater deceleration is necessary, the system transmits the brake fluid pressure control signal to the ABS actuator and electric unit (control unit) operates the brake.
Following	The system controls electric throttle control actuator and the brake fluid pressure to keep the proper distance between the vehicles according to the vehicle speed change of the vehicle ahead.
Acceleration	When a vehicle ahead is not detected because of it changes lanes or own vehicle changes lanes during the following driving, the system controls the electric throttle control actuator in the open direction and accelerates the vehicle to the set vehicle speed slowly.

Set Condition

Under a standby state, pushing down the SET- switch will start system control.

When vehicle speed is between approximately 30 and 144 km/h (20 and 89 MPH)
When vehicle speed is below approximately 30 km/h (20 MPH) if the vehicle ahead is detected. The set vehicle speed becomes 30 km/h (20 MPH).

If the system is canceled by conditions 1-10 below, the system will resume control at the last set cruising speed by pushing up the RES+ switch.

NOTE:

When the SET- switch is pushed under the following conditions, the system cannot be set and the set vehicle speed indicator will blink for approximately 2 seconds.
- When traveling below 30 km/h (20 MPH) and the vehicle ahead is not detected.
- When the selector lever is not in the "D" position or manual mode.
- When the parking brakes are applied.
- When the brakes are operated by the driver.

When the SET- switch is pushed under the following conditions, the system cannot be set.
- When the VDC is OFF. (To use the ICC system, turn ON the VDC system, push the MAIN switch to turn OFF the ICC system and reset the ICC system by pushing the MAIN switch again.)
- When ABS or VDC (including the TCS) operates.
- When the wheel is slipping. (To use the ICC system, make sure the wheels are no longer spinning, push the MAIN switch to turn OFF the ICC system and reset the ICC system by pushing the MAIN switch again.)

Cancel Conditions

When CANCEL switch is pressed.
When brake pedal is depressed.
When the parking brakes are applied.
When the system judges the vehicle is at standstill.
When ABS or VDC (including the TCS) operates.
When a wheel slips.
When the VDC is turned OFF.
When the MAIN switch is turned OFF.
When the system malfunction occurs.
