  • Traction Control & Stability
  • Electronic Stability Program (ESP®)

    This safety breakthrough first introduced by Mercedes-Benz continually monitors your driving inputs and the vehicle's motion to help keep it going in your intended direction, especially in corners and during evasive maneuvers. If it detects wheelspin, severe understeer (plowing), or oversteer (fishtailing), ESP can brake individual wheels and reduce engine power to help bring the vehicle under control.[*5]

Brakes, Wheels, and Tires

  • Brakes
  • Adaptive Brakes

    Adaptive Braking technology integrates a suite of advances. If you lift off the accelerator quickly, Predictive Brake Priming sets the pads closer to the discs for more immediate response when you apply the brakes. In the rain, Automatic Brake Drying periodically applies the brakes just enough to sweep water build-up from the discs. During uphill starts, Hill-Start Assist helps prevent unwanted rollback. And a HOLD feature can make long red lights or stopped traffic a little easier.[*4]

  • Brake Assist

    Brake Assist senses emergency braking via the speed at which the driver presses the brake pedal and immediately applies maximum available power boost. Brake Assist can potentially reduce the overall stopping distance by eliminating the delay caused by a common human tendency not to brake hard enough, soon enough. Letting up on the brake pedal releases Brake Assist.[*4]

  • Wheels

    18-inch 5-spoke alloy wheels

  • Tires

    235 40 R 18 front and 255/ 35 R18 rear, all-season

Safety and Security Systems

  • Restraint Systems
  • 9-way air bag protection

    An advanced system of 9 air bags offers enhanced occupant protection. Pelvic air bags complement the front-seat side-impact air bags. A driver´s knee air bag augments dual-stage front air bags. And side curtain air bags are provided for the front seats, something you won't find in many other Cabriolets. Rear side-impact air bags are optional.[*6]

  • Seat belt technology

    Arguably our most important passive safety feature, all four 3-point seat belts are equipped with Emergency Tensioning Devices (ETDs) and belt force limiters. If a collision exceeds a preset threshold, ETDs instantly remove slack from the seat belts. Belt force limiters allow a slight amount of give in the seat belts, to reduce the peak seat-belt forces on the occupant.

  • Rear side-impact air bags

    In addition to the 9 standard air bags in the E350 Cabriolet, side-impact air bags are optionally available for each rear seating position.[*6]

  • NECK-PRO head restraints

    In the case of a rear impact exceeding a preset threshold, NECK-PRO front head restraints move forward and slightly upward, reducing the distance between the head restraints and the heads of front-seat occupants. This action helps to reduce the possibility or severity of whiplash-type neck injuries.

  • Locking & Security
  • SmartKey

    The SmartKey remote control integrates remote door locks and trunk opener, a removable valet key, and a remote panic alarm. You may selectively unlock only the driver's door and fuel filler, or both doors plus the trunk and fuel filler.

  • Mercedes-Benz mbrace

    From your car, online or via the mbrace Mobile Application on your compatible smartphone, mbrace™ helps keep you connected with nearly 20 different security, destination planning and convenience services. Combining advanced technology with 24-hour support from helpful experts, two available service packages can help you plan a trip, remember where you parked, or even handle an unexpected emergency. Every new Mercedes-Benz equipped with mbrace includes a complimentary 6-month trial subscription.[*7,*8,*9]

  • Antitheft alarm system

    The standard antitheft alarm system is armed automatically when you lock your Mercedes from the outside. It sounds the horn and flashes the exterior lights if a door, the trunk or the hood is opened without first unlocking the vehicle. You can also sound the alarm by pressing the red "panic" button on your SmartKey remote when you're within range of your vehicle.
