FROM 2014 THROUGH 2016 THE INTELLIGENT DRIVE AND THE DRIVER ASSISTANCE PACKAGE DOES NOT WORK. I KEEP SAYING THE S550 THINKS 200 FEET IS 90 FEET AND 100 FEET IS 30 FEET. WHAT I MEAN TO SAY IS THE SYSTEMS THINK 90 FEET DISTANCE IS 200 FEET AWAY AND 30 FEET IS 100 FEET AWAY. IT DOES NOT MEASURE THE DISTANCE PROPERLY. IT COULD BE, AND MOST LIKELY, A PROGRAMING ISSUE. IT IS THE SAME ON ALL THE 2014 THROUGH 2016 S550'S I HAVE TRIED. THE OTHER THING IT DOES WITH THE DISTRONIC CRUISE CONTROL IS WHEN IT STARTS TO BRAKE, THE DISTANCE SET DECREASES AND THE CAR SPEEDS UP AND AGAIN THE DISTANCE SET DECREASES AND THE CAR SPEEDS UP AND SO ON. IT CHANGES THE DISTANCE ( YOU CAN SEE IT HAPPEN IN THE IN THE MENU SETTING ON THE SPEED AND TACHOMETER SCREEN) AS SOON AS THE CAR AUTONOMOUSLY BRAKES. SET IT AT 200 FEET AND IN REALITY IT IS 90 FEET AND AS SOON AS IT BRAKES THE DISTANCE TO KEEP INSTANTLY DROPS TO JUST UNDER WHAT IT IS SET AT SO THE CAR THINKS THE DANGER IS OVER AND SPEEDS UP AGAIN AND THEN BRAKES AGAIN. AND YOU KEEP GETTING CLOSER AND CLOSER TO THE CAR IN FRONT BECAUSE THE SET DISTANCED KEEPS CHANGING AND YOU HAVE TO BRAKE SO YOU DO NOT HIT THE CAR IN FRONT BECAUSE THE S550 WON'T. I HOPE THIS MAKES SENSE. IT IS EASIER TO SHOW WITH THE DISTANCE GRAPHIC UP ON THE SCREEN. THE WHOLE SYSTEM IS COMPLETELY SCREWED UP. AS IS THE LED LIGHTING SYSTEM IN THE SNOW AND FREEZING RAIN AND SLUSH. CANNOT DRIVE IT AT NIGHT IN A WINTER STORM. IT ALL HAPPENS AROUND TOWN TO HIGHWAY SPEEDS. I WAS ACTUALLY TOLD BY THE SERVICE MANAGER FOR THE DISTRONIC CRUISE TO WORK I HAVE TO BE DRIVING FASTER THAN 75 MPH. MY 2007 S550 4 MATIC'S DISTRONIC AND AUTONOMOUS BRAKING WORKED PERFECTLY.
