If the radar or cover is dirty or obscured with foreign matter such as snow, this message (“Smart Cruise Control disabled temporarily”) will appear and it will disappear after for a while. In this case, the system may not function temporarily, but it does not indicate a malfunction of the smart cruise control System. Clean the radar or cover by using a soft cloth and it will operate normally.
If the radar front is polluted after the engine has been turned on, or the radar cannot detect any external object (when the vehicle is located in open, empty surroundings), the smart cruise control system may not operate properly.
