Hyundai Ioniq: Smart Cruise Control System / Sensor to Detect Distance to the Vehicle Ahead

The Smart Cruise Control uses a sensor to detect distance to the vehicle ahead.

Warning message

Smart Cruise Control disabled. Radar blocked

When the sensor lens cover is blocked with dirt, snow, or debris, the Smart Cruise Control System operation may stop temporarily. If this occurs, a warning message will appear on the LCD display. Remove any dirt, snow, or debris and clean the radar sensor lens cover before operating the Smart Cruise Control System. The Smart Cruise Control system may not properly activate, if the radar is totally contaminated, or if any substance is not detected after the vehicle is in the ready () mode (e.g. in an open terrain).

CAUTION

• Do not apply license plate frame or foreign objects such as a bumper sticker or a bumper guard near the radar sensor. Doing so may adversely affect the sensing performance of the radar.
• Always keep the radar sensor and lens cover clean and free of dirt and debris.
• Use only a soft cloth to wash the vehicle. Do not spray pressurized water directly on the sensor or sensor cover.
• Be careful not to apply unnecessary force on the radar sensor or sensor cover. If the sensor is forcibly moved out of proper alignment, the Smart Cruise Control System may not operate correctly. In this case, a warning message may not be displayed. Have the vehicle inspected by an authorized HYUNDAI dealer.
• If the front bumper becomes damaged in the area around the radar sensor, the Smart Cruise Control System may not operate properly. Have the vehicle inspected by an authorized HYUNDAI dealer.
• Use only genuine HYUNDAI parts to repair or replace a damaged sensor or sensor cover. Do not apply paint to the sensor cover.

Check Smart Cruise Control System
