The Smart Cruise Control uses a sensor to detect distance to the vehicle ahead.
If the sensor is covered with dirt or other foreign matter, the vehicle to vehicle distance control may not operate correctly.
Always keep the sensor clean.
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 cluster 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 turning on the engine (e.g. in an open terrain).
Information
For the SCC operation is temporarily stopped if the radar is blocked, but you wish to use conventional cruise control mode (speed only control function), you must convert to the cruise control mode (refer to "To convert to Cruise Control mode" in the following page).
CAUTION
Check Smart Cruise Control System
The message will appear when the vehicle to vehicle distance control system is not functioning normally. Take your vehicle to an authorized HYUNDAI dealer and have the system checked.
