Neither NHTSA (National Highway Traffic Safety Administration) nor the IIHS (Insurance Institute for Highway Safety) has crash-tested the 2010 Mercedes-Benz SLK, but its list of safety features is unparalleled among roadsters.
Head-and-thorax side-impact airbags and a knee airbag are standard, as are anti-lock brakes and electronic stability control. Cars.com confirms all SLKs include "antilock brakes, side-impact airbags, knee airbags and an electronic stability system." Edmunds adds a "brake assist" feature is included, along with Mercedes-Benz's "TeleAid emergency call system" that contacts authorities in case of an accident. ConsumerGuide reminds drivers that all 2010 SLK-Class convertibles come with "daytime running lights" and a "tire-pressure monitor." J.D. Power points out "all 2010 SLKs will carry integrated roll bars," which pop up in case of a rollover to protect passengers.
The seating position is quite low, so visibility can be an issue; when the top is raised, it's particularly difficult to see to the rear quarters. Edmunds reports this major "drawback involves the SLK's inferior sight lines, as the intricately constructed roof unavoidably creates significant blind spots."
