2012 Mercedes-Benz SLS AMG: Good Parking Sensors
April 26, 2013
Unless you're parking the SLS next to a big mirror-tinted window, there's no way to judge the limits of the nose without using the parking sensors. And it's a good thing those parking sensors are as accurate as they are.
Besides the audible beeping that speeds up as you get closer to an object, there's a visual marker on the dash and just behind and between the seats. These lights start out as amber and go to red. The cool thing about the rear indicator lights is that you can see them in the rearview mirror as you back up.
Pictured above is the distance from a typical parking block when the red lights just activate. Now THAT, is close. You can still slide an index card between the splitter and the block, but probably not two.
