AIRMATIC® employs electronically controlled semi-active air springs that adjust to changing driving conditions. Along with selectable Sport and Comfort modes, the system also lowers the car at higher speeds for improved aerodynamics and stability. Automatic 4-wheel level control helps compensate for additional cargo or passengers. The Adaptive Damping System (ADS II) continually optimizes ride and handling by automatically selecting one of four damping profiles for each spring-strut every time a wheel moves up or down.

Traction Control & Stability
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. It also 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]
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]
4-wheel disc, with perforated and internally ventilated front discs with 4-piston calipers.
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)
BAS® 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]
A Mercedes-Benz first, PRE-SAFE® can detect instability during certain vehicle maneuvers that suggest a collision or rollover is imminent. It can then adjust the front passenger seat, and close the front windows and sunroof — all in an effort to better prepare the occupants in the moments before a collision. If no accident occurs, you simply readjust your seat, reopen the windows and sunroof, and continue on your way.[*6]
Integrated Restraint System
An advanced system of 9 air bags offers 11-way occupant protection. Dual two-stage front air bags, a driver's knee air bag, front and rear side-impact air bags, and side curtain air bags for both seating rows are standard.[*7]
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.[*7]
Seat belt technology
Equipped with Emergency Tensioning Devices (ETDs) and belt force limiters, 3-point seat belts are arguably our most important passive safety feature. If a collision exceeds a preset threshold, the ETDs instantly remove slack from the front and rear outboard seat belts. Belt force limiters allow a slight amount of give in the ETD-equipped 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 rear seating positions. Selectable passenger seat-belt retractors help secure child seats.
The first system of its kind, ATTENTION ASSIST® continuously monitors up to 70 different parameters of driving behavior, and can automatically alert the drive with both visual and audible warnings if it detects signs of drowsiness on long trips. [*8]
From your car, online or via the mbrace Mobile App 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 trial subscription to the mbrace Packages.[*9,*10,*11]
Locking & Security
The SmartKey remote control integrates remote door locks, 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.
Driver-programmable driveaway locking
Automatically locks the doors when the car reaches 9 mph.
Night security illumination
Uses the car's exterior lights to help illuminate a path after parking.
Antitheft alarm with remote panic feature
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.
Uses the car's lights to help illuminate a return path when the car is remote-unlocked in darkness.
Integrated 3-button garage door control
Three buttons on the rear view mirror can be programmed to operate many types of garage door openers, security gates and other HomeLink-compatible features.
mbrace Remote Door Unlock
Allows remote unlocking of the vehicle via the mbrace Mobile App or via telephone.
mbrace GPS-based Stolen Vehicle Recovery
Helps law enforcement agencies track and recover stolen vehicles.
mbrace Antitheft Alarm Notification
Alerts Mercedes-Benz to contact vehicle owner if antitheft alarm sounds.
