  • Chassis and Traction Control/Stability Systems

    Chassis and Traction Control/Stability Systems

    Chassis
    AGILITY CONTROL suspension
    Engineered specifically for performance driving, AGILITY CONTROL automatically adjusts the individual shock absorbers based on the road surface and the driver's current driving style. Valving inside each shock absorber automatically firms up during stronger body motions for sharper handling feedback and stability, and reduces the damping rates during gentler motions for a smoother, more composed ride.
    Lowered, sport-tuned suspension
    C-Class Sport Sedans boast firmer coil springs and shock absorbers, as well as a lowered ride height, for sharper handling response and a more aggressive stance.
    Steering type
    Rack-and-pinion with power assist
    Turning circle

    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.[*4]
    4MATIC all-wheel drive
    In any season, on any road, 4MATIC® all-wheel drive adds to your confidence and control. Always engaged and optimizing torque to every wheel, 4MATIC integrates with ESP®, our standard Electronic Stability Program, for maximum effectiveness in corners and slippery conditions.
    4-wheel Electronic Traction System (4-ETS)
    4MATIC all-wheel drive incorporates our 4-wheel Electronic Traction System (4-ETS®), which monitors for the first sign of wheel slip and responds to ensure torque is sent to the wheels with the best grip, even if that's only one wheel.
  • Brakes, Wheels, and Tires

    Brakes, Wheels, and Tires

    Brakes
    Adaptive braking technology
    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 brake HOLD feature can make long red lights or stopped traffic a little easier.[*5]
    Antilock Braking System (ABS)
    ABS senses impending wheel lockup under heavy braking and pumps the front brakes individually or the rear brakes together. This intelligent system can pump the brakes as needed up to 30 times per second, to prevent lockup and preserve the driver's steering ability.[*5]
    Brake Assist (BAS®)
    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.[*5]
    Wheels/Tires
    Wheels
    17-inch twin 5-spoke wheels (7.5x17 front and 8.5x17 rear)
    Tires
    225/45R17 front and 245/40R17 rear, all-season
  • Safety and Security Systems

    Safety and Security Systems

    Safety Features
    ATTENTION ASSIST®
    The first system of its kind, ATTENTION ASSIST continuously monitors different parameters of driving behavior, and can automatically alert the driver with both visual and audible warnings if it detects signs of drowsiness on long trips.
    Mercedes-Benz mbrace®
    From your car, your computer or your compatible smartphone, mbrace2™ offers the industry's most comprehensive range of features for more connected, safe and productive drive time. From making your everyday life easier to helping out in an emergency, mbrace2 combines advanced cloud-based and GPS technology with 24-hour support from helpful experts. Three mbrace packages are offered, and every 2014 Mercedes-Benz includes a 6-month mbrace trial subscription.
    Restraint Systems
    Integrated Restraint System
    An advanced system of 9 air bags offers 11-way occupant protection. Dual two-stage front air bags, front side-impact air bags, front pelvic air bags, a driver's knee air bag, and side curtain air bags for both seating rows are standard.[*6]
    Side curtain air bags
    In a side impact exceeding a preset threshold, a multi-chamber air bag deploys along the front and rear side windows on the affected side of the vehicle. An integrated rollover sensor automatically deploys the ETDs and, if deemed necessary, the side curtain air bags in the event of a detected rollover.[*6]
    Seat belt technology
    Arguably our most important passive safety feature, all four outboard 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.
    Occupant Classification System (OCS)
    OCS automatically turns the front passenger's front air bag on or off and adjusts the air bag inflation rate based on the weight category determined by weight sensor readings from the front passenger seat.
    ISOFIX / Universal LATCH system (Lower Anchors and Tethers for Children)
    Standardized child-seat attachments are provided at both outboard rear seating positions. Selectable passenger seat-belt retractors help secure child seats.
    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 all doors plus the trunk and fuel filler.
    Locator lighting
    Locator lighting uses the car's lights to help illuminate a return path when the car is remote-unlocked in darkness. Unlocking the car also activates the illuminated entry system.
    Emergency trunk opener
    An emergency release lever is located inside the trunk and illuminated for 60 minutes after the trunk lid is closed.
    Night Security Illumination
    The exterior lights can be programmed to turn on for a preset interval when you remote-lock your vehicle in darkness, to help light a path for you as you leave.
