The Intelligent Cruise Control (ICC) system:
• Uses a radar sensor located on the front of the vehicle to detect vehicles traveling ahead.
• Helps maintain a selected distance from the vehicle ahead within the approximate speed range of 20 MPH to 90 MPH (32 km/h to 144 km/h), depending on the set speed.
• Decelerates by controlling the throttle and applying the brakes to match the speed of a slower vehicle that is detected in the lane ahead.
• Maintains the driver selected distance by controlling the traveling speed based on the speed of the vehicle ahead.
NOTES:
• The distance to the vehicle ahead will change according to the vehicle speed. The higher the vehicle speed, the longer the distance.
• When the ignition is cycled ON/OFF/ON, the distance setting defaults (resets) to “Long.”

Switch Name and Function
Detection Zone
The detection zone of the ICC sensor is limited. A vehicle ahead must be in the detection zone for the Intelligent Cruise Control to maintain the selected distance from the vehicle ahead. The detection zone is an area directly in front of your traveling vehicle. Vehicles in adjacent lanes are usually outside the detection zone.

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 the selector lever is not in the D (DRIVE) position or manual mode.
– When the parking brake is applied.
– When the brakes are operated by the driver.
• When the SET – switch is pushed under the following conditions, the system cannot be set and a warning chime will sound and a message will pop up in the combination meter (information display):
– 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 a 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
1. When the CANCEL switch is pressed
2. When the brake pedal is depressed
3. When the vehicle ahead is not detected below the speed of 15 mph (24 km/h)
4. When the selector lever is not in the D (DRIVE) position or manual mode
5. When the parking brake is applied
6. When the system judges the vehicle is at a standstill
7. When the ABS or VDC (including the TCS) operates
8. When the MAIN switch is turned OFF
9. When a wheel slips
10. When the VDC is turned OFF
11. When a system malfunction occurs
Note: When the ICC system is automatically canceled, the cancellation condition can be displayed in “Work support” of CONSULT (ICC/ADAS).

CAUSE OF AUTO-CANCEL 5
Description
Displays causes of automatic system cancellation that occurred during control of the Intelligent Cruise Control (ICC).
CONSULT Function (ICC/ADAS)
CONSULT performs the following functions via CAN communication using the ADAS control unit.
CONSULT Function LASER/RADAR)
CONSULT performs the following functions via CAN communication with the ADAS control unit and the communication with the ICC sensor.
Active Test
• NEVER perform “Active Test” while driving the vehicle.
• The “Active Test” cannot be performed when any of the following system malfunctions are displayed.
– ICC system
– Blind Spot Warning/RCTA
– PFCW/FEB
• The “Active Test” cannot be performed when the FEB warning lamp is illuminated.
• The “Active Test” cannot be performed when the ICC system is ON.
Additional Service When Replacing ICC Sensor
Always perform the radar alignment aiming adjustment after removing and installing or replacing the ICC sensor.
The system does not operate normally unless the ICC sensor is aligned properly.
• Perform the ICC system action test to check that the ICC system operates normally.
• The ICC system is designed to automatically check the sensor’s operation within the limitations of the system.
