The 2009 Mercedes-Benz E-Class leaves very little to want in terms of safety features or capabilities.
In tests conducted by the Insurance Institute for Highway Safety (IIHS), the 2009 Mercedes-Benz E-Class rates "good" for frontal offset, "acceptable" for side impact, and "good" for rear crash protection. In National Highway Traffic Safety Administration (NHTSA) crash tests, the 2009 Mercedes-Benz E-Class fares well. The Mercedes-Benz 2009 E-Class sedan receives four stars for front impact protection, five stars for side impact protection, and four stars for rollover resistance.
Unique safety features of the 2009 Mercedes-Benz E-Class include "an adaptive brake light that flashes when the car is under rapid or panic braking,” notes Cars.com. That's a safety feature meant for people following behind the Mercedes-Benz. They conclude, "If all else fails and the Mercedes-Benz E-Class does crash, the standard Tele-Aid—which is similar to GM's OnStar—will contact authorities and send them to your location."
Edmunds explains that avoiding accidents is partly the result of being able to see well from the driver's seat. "Long a Mercedes feature, the power drop-down of the rear headrests made parallel parking less of a hassle, although it would be nice if Mercedes included parking assist as standard equipment. (It's optional.)"
"All 2009 Mercedes-Benz E-Class models come with stability control, antilock brakes, front and rear side airbags, full-length side curtain airbags and the TeleAid emergency system," according to Edmunds.
Also standard is what Mercedes-Benz 2009 reviews call PRE-SAFE. Cars.com explains: "If the radar sensor predicts an impending collision, Pre-Safe cinches the front seat belt pretensioners and can even change the position of the front passenger seat for optimal protection by the restraints." Furthermore, "In a serious skid, the [Mercedes-Benz E-Class' PRE-SAFE] system closes the moonroof and any open windows, a step to prevent occupant ejection, which can occur in a collision or, especially, a rollover."
