The Dynamic Handling suspension alters the damping rates at the touch of button. The electronically controlled shock absorbers independently adjust for each wheel based on the current driving situation. A choice of Comfort and Sport settings lets you match the car's handling and ride characteristics to your mood.

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]
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.[*7]
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.[*7]
18-inch AMG® twin 5-spoke (8.0x18 front and 8.5x18 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.[*6]
Another Mercedes-Benz safety breakthrough, PRE-SAFE® can detect instability during certain vehicle maneuvers that suggest a collision or rollover is imminent. It can then tighten the seat belts, adjust the occupied front passenger seat, and close the front side windows, 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 continue on your way.[*8]
COLLISION PREVENTION ASSIST PLUS
Radar-based technology alerts you if you're approaching a vehicle ahead, or even some stationary objects, at a speed and distance that suggest a collision is likely. As soon as the driver starts to brake, its Adaptive Brake Assist automatically provides the ideal level of braking, to help prevent a collision or reduce its severity. New for 2015, the system can also provide autonomous braking from speeds up to 65 mph, and can activate the features of PRE-SAFE®.[*9]
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 trial period for each package.[*10, *11, *12]
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.[*5]
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.[*5]
Seat belt technology
Arguably our most important passive safety feature, all four 3-point seat belts are equipped with Emergency Tensioning Devices (ETDs) to instantly remove slack If a collision exceeds a preset threshold. Belt force limiters allow a slight amount of give in the seat belts, to reduce the peak seat-belt forces on the occupant. Front seat-belt presenters automatically extend when the door is closed, to make it easier for the occupants to fasten their belts.
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.[*13]
NECK-PRO front 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.
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.[*5]
Locking & Security
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.
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
Night security illumination uses the car's exterior lights to help illuminate a path after parking.
Driver-programmable driveaway locking
Automatically locks the doors when the car reaches 9 mph.
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.
Integrated 3-button garage door control
Compatible with HomeLink® components and some other systems.
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.
