I've done a search on this but haven't found any info. I have noticed since picking up the car that the warning light nor audible sound has not come on during my drives. I have set the system for long, normal and short and have had cars pull in front at short range but have seen nothing. I have activated the ACC and made sure that works, since they both use the same radar module. I have checked the manual and online manual to see if there is a fuse for that system which is burnt out but did not see one listed. Any ideas?
