Today, tomorrow and the day after: all the safety innovations at a glance:
Cornering lights: this function of the bi-xenon headlamps and the Intelligent Light
System provides more safety on junctions and when driving slowly on tight bends.
ADAPTIVE BRAKE: this Mercedes brake system offers assistance functions, such as a HOLD function and Hill Start Assist, for even greater safety and comfort.
Adaptive front airbags: the front airbags deploy in two stages, depending on accident
Adaptive Main Beam Assist: this system adjusts the range of the headlamps in
accordance with the distance to oncoming vehicles/vehicles travelling ahead.
Adaptive brake lights: flashing brake lights warn vehicles behind in an emergency
Active Light System: the Intelligent Light System’s bi-xenon headlamps follow the driver’s steering movements.
Active Bonnet: in the event of an accident, the rear of the bonnet is raised by 50
millimetres in order to reduce the risk of injury to pedestrians.
ATTENTION ASSIST: this Mercedes system detects driver drowsiness and gives a
Motorway mode: from 90 km/h the entire width of the carriageway is illuminated,
improving the driver’s range of vision by around 50 metres.
Belt Bag: this widened section of the seat belt is activated by the airbag control unit when the crash sensors detect a serious impact. A generator at the belt armature inflates the double-layered belt, which has Velcro seams. The increase in belt width distributes the forces over a wider area, thereby reducing the risk of injury.
Bi-xenon headlamps: gas-discharge lamps for low and main beam improve safety at night.
Braking Bag: This auxiliary brake accommodated in the vehicle floor is a new type of PRE-SAFE® component. If the sensor system concludes that an impact is unavoidable, the Braking Bag is deployed shortly before the crash and stabilises the car on the road surface by means of a friction coating. The vehicle’s vertical acceleration increases the friction, and helps to decelerate the vehicle before the impact occurs.
Brake Assist PLUS: this system uses radar sensors to recognise an impending rear-end collision, calculates the necessary degree of braking assistance and makes it available immediately when the driver presses the brake pedal.
Child Cam: a small camera in the roof lining helps drivers to keep an eye on children travelling in the rear.
Child Protect: innovative child safety seat system with a metal frame and padded elements. It improves protection during a side impact, and is also considerably more comfortable.
DISTRONIC PLUS: this radar-based proximity control system automatically keeps the car at a set distance from the vehicle in front, braking it to a standstill if necessary and accelerating when the gap ahead is sufficiently large. If the distance to the vehicle ahead decreases too quickly, the system gives the driver visual and audible warnings.
Enhanced foglamps: This function of the Intelligent Light System pivots the offside headlamp outwards to illuminate the road verge more effectively.
Headlamp Assist: a sensor on the windscreen automatically switches the headlamps on when darkness falls.
Main Beam Assist: a camera on the inside of the windscreen recognises oncoming
traffic and automatically dips the headlamps – then switches back to main beam.
Speed Limit Assist: a camera fitted behind the windscreen detects speed limit signs at the roadside. The relevant limit is then displayed in the instrument cluster.
Belt force limiters: this technology reduces the force exerted by the belt strap on the seat occupant during a crash.
Belt tensioners: any slack in the seat belt strap is instantly taken up during a crash to reduce the forward movement of the occupants caused by the impact.
Hybrid Battery Shield: extensive protective measures for the lithium-ion battery of the S 400 HYBRID, which are integrated into the seven-stage safety concept. This innovative battery is accommodated in a high-strength steel housing, and also secured in place. Bedding the battery cells in a special gel effectively dampens any jolts and knocks. There is also a blow-off vent with a rupture disc and a separate cooling circuit. An internal electronic controller continuously monitors the safety requirements and immediately signals any malfunctions.
Intelligent Light System: This innovative headlamp technology provides five lighting functions which are activated depending on the driving and weather conditions (also see Cornering lights, Country mode, Motorway mode, Active Light System and Enhanced foglamps).
Interactive Vehicle Communication: cars are able to communicate directly with each other, or via relay stations. Using “ad hoc” networks and WLAN radio technology, they are e.g. able to receive and transmit warnings of bad weather or obstacles in the road.
Interseat Protection: these protective systems for the first and second seat rows physically separate the occupants if the PRE-SAFE® system registers an accident. During an impact, they therefore help to ensure that the passengers do not come into contact and injure each other.
Child seat recognition: A transponder system automatically recognises whether a rear-facing child seat is installed, and deactivates the front passenger airbag if this is the case.
Kneebag: in the event of a crash, an additional airbag reduces the forward movement of the driver caused by the impact.
Night View Assist PLUS: the display in the dashboard shows a realistic grey-scale image from an infrared camera that monitors the road ahead of the vehicle. Any pedestrians detected are additionally highlighted in the display.
Country mode: this function of the Intelligent Light System replaces the previous low-beam headlamps and provides broader and brighter illumination of the opposite road verge.
LED-Array: groups of LED elements that replace conventional headlamps. The individual LEDs (Light Emitting Diodes) can be controlled separately (see Partial Main Beam and Spotlight)
NECK-PRO head restraints: crash-responsive head restraints support the heads of the driver and front passenger at an early stage during a rear-end collision, reducing the risk of a whiplash injury.
Partial Main Beam: this enables the driver to leave the main beams constantly switched on. Once the system recognises oncoming traffic with the help of a camera, it automatically adjusts the light distribution accordingly.
PRE-SAFE®: anticipatory safety measures are taken to protect the occupants if an
accident risk is detected.
PRE-SAFE® Brake: if there is imminent danger of a rear-end collision, this system
brakes the vehicle automatically if the driver fails to react.
PRE-SAFE 360°: when the system recognises an impending rear-end collision, the stationary vehicle is automatically braked. This helps to prevent secondary accidents and mitigate the severity of possible whiplash injuries.
PRE-SAFE Pulse: This further development of PRE-SAFE® is able to reduce the forces acting on the torsos of the occupants during a lateral collision by around one third. It does this by moving them towards the centre of the vehicle by up to 50 millimetres as a precautionary measure. As an active restraint system, it uses the air chambers in the side bolsters of the seat backrests.
PRE-SAFE Structure: The inflatable metal structures save weight or increase the stability of structural components. When at rest, the metal section is in a folded state to save space. If its protective effect is required, a gas generator builds up an internal pressure of 10 to 20 bar within fractions of a second, causing the section to unfold for significantly more stability.
Real Life Safety: Mercedes philosophy for comprehensive safety. This takes the findings from accident research into account, and integrates all the active and passive safety
Reversing camera: as soon as reverse gear is selected, the dashboard display shows the image from a camera covering the area immediately to the rear of the coupe.
Sidebags: these airbags reduce the risk of injury in a collision from the side.
Side Reflect: special reflective strips inset into the door seals and tyres. These are invisible during the daytime, but make the vehicle’s silhouette more easily visible at night.
Size Adaptive Airbags: these airbags automatically adjust their volume according to the seating position and stature of the front passenger which have been recognised by sensors. The system uses three retaining straps to adjust the airbag contour, and therefore limit the volume.
Spotlight lighting function: This partial LED main beam specifically illuminates potential hazards. If the infrared camera of Night View Assist PLUS e.g. detects deer at the roadside or pedestrians in the road, these can be briefly illuminated beyond the normal area covered by the main beams, as if by a spotlight.
Lane Keeping Assist: a camera behind the windscreen recognises clear carriageway markings and gives a warning if the car unintentionally leaves its lane.
Blind Spot Assist: this radar-based system warns the driver before a lane-change if it
detects another vehicle in the exterior mirror’s blind spot.
Windowbags: like a curtain, these large airbags extend from the A to the C-pillar in a side impact.
