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]
Perforated, slotted and ventilated 15.4-inch front discs with compound rotors and 6-piston calipers. Perforated and ventilated 14.2-inch rear discs with 4-piston fixed-type calipers.[*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]

Integrated Restraint System
An advanced system of 8 air bags includes dual two-stage front air bags, dual side-impact air bags, dual knee air bags, and upward-deploying head air bags.[*6]
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 seat belts. Belt force limiters allow a slight amount of give in the seat belts and reduce the peak seat-belt forces on the occupant.
Occupant Classification System (OCS)
OCS automatically turns the 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 passenger seat.[*7]
Locking & Security
The SmartKey remote control integrates remote door locks and trunk opener, a removable valet key, and a remote panic alarm.
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.
