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.

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]
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.[*4]
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.
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]
19-inch triple 5-spoke wheels (7.5 x 19 front and rear)
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.[*11]
From your car, your computer or your compatible smartphone, mbrace 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, mbrace combines advanced cloud-based and GPS technology with 24-hour support from helpful experts. Three mbrace packages are offered, and every 2015 Mercedes-Benz includes a 6-month mbrace trial subscription.[*7]
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.[*10]
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
The SmartKey remote control integrates remote door and liftgate locks, 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 liftgate and fuel filler.
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.
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.
