PRE-SAFE в Mercedes-Benz E-Class W212
PRE-SAFE® – это комбинация систем, которые реагируют заблаговременно и запускают упреждающие меры по защите водителя и пассажиров. В комплекс PRE-SAFE®, помимо реверсивных преднатяжителей передних ремней безопасности, входит также автоматическое закрывание окон и подъёмно-сдвижного люка (если заказан). Кроме того, воздушные камеры новых динамических мультиконтурных сидений могут в опасных ситуациях за пару секунд автоматически наполняться, чтобы при возможной аварии ещё эффективнее удержать водителя и переднего пассажира. Если сиденье переднего пассажира оснащено системой запоминания параметров, то при угрозе аварии оно будет автоматически приведено в наиболее безопасное положение. Функции PRE-SAFE® активизируются, например, в случаях экстренного торможения, в ситуациях избыточной либо недостаточной поворачиваемости, а также когда водитель резко поворачивает рулевое колесо при движении на высокой скорости. При угрозе столкновения, если автомобиль дополнительно оснащён системой адаптивного круиз-контроля DISTRONIC PLUS, система PRE-SAFE® сработает в результате информации, полученной от радарных датчиков системы DISTRONIC PLUS.

What is Mercedes Pre-Safe?
Aside from being a leader in luxury and a preeminent status symbol brand, Mercedes-Benz is known for pushing the boundaries on safety and technology. To that end, the accident sensing Mercedes-Benz Pre-Safe system prepares the occupant compartment by optimizing passenger safety in the moments preceding a collision or single-car crash, including a rollover event.
Pre-Safe employs a series of sensors to detect instabilities caused by sudden braking or steering that would upset the balance of a vehicle. The radar-based sensors also detect approaching vehicles on a potential collision course with a Mercedes. Multiple versions of Pre-Safe are available, and they are standard or optional, depending on the model and equipment.
What Does Pre-Safe Do? — Find the best Mercedes-Benz deals!
Upon detecting a potential crash situation, the Pre-Safe system immediately responds with a series of measures to elevate passenger protection. This action includes the tightening of front seatbelts and the repositioning of headrests and seats to help mitigate trauma. Pre-Safe will also attempt to close the windows and sunroof before a collision, which helps to minimize exterior debris from entering the vehicle at high speeds and causing further injury. It also helps prevent an occupant from ejection during a collision.
In addition, the system can also initiate full autonomous braking if it detects a collision with an object ahead. The Pre-Safe Brake feature works in tandem with Distronic Plus, Mercedes-Benz’s adaptive cruise control system, to avoid a collision or reduce the severity of an impact. This function is especially useful when traffic ahead suddenly stops.
Pre-Safe technology offers additional safety measures through Pre-Safe Plus to reduce the effects of a rear-impact crash, Pre-Safe Impulse Side to protect passengers in a lateral collision, and Pre-Safe Sound to protect occupants’ hearing during a crash.
What is Pre-Safe Plus? — Find the best Mercedes-Benz deals!
Pre-Safe Plus helps prevent rear collisions or lessens the effects of these kinds of crashes. If the car’s rear radar detects a potential rear-end collision, Pre-Safe Plus rapidly flashes the rear hazard warning lights to warn the driver approaching from behind to slow down or stop.
In the moments before a sensed collision, the system also activates the reversible belt tensioners while moving the seat backrests to an upright position. And if the vehicle is stationary in a rear collision situation, such as when resting at a stoplight, the system will increase the braking force, holding the car as securely as possible to prevent or lessen a secondary crash with the vehicle ahead.
Pre-Safe Impulse Side — Find the best Mercedes-Benz deals!
Pre-Safe Impulse Side evaluates information from the front and side radar systems to detect an imminent lateral impact. Before the side impact occurs, this system protects the occupant sitting in the front seat on the side of the collision by instantaneously inflating an air chamber on the outer side bolster of the seat. This action pushes the occupant toward the middle of the vehicle’s cabin and away from the side of the car. As it increases this distance between the occupant and the door, it potentially reduces the force of the impact on the human body, lessening the severity of injuries.
Pre-Safe Sound — Find the best Mercedes-Benz deals!
This innovative feature of the Pre-Safe system activates a protective mechanism of the human ear by playing a short noise signal through the stereo speakers when a potential accident is detected. The ear’s natural reflex to this sound protects it from the noise pressure and high decibels caused by a collision, which can otherwise injure the ear and affect your hearing.

Luxury through peace of mind.
To deliver the best or nothing, safety must come first. It’s why we devote so much time to a moment we hope never happens, and why every Mercedes-Benz is engineered to make an accident less severe, less damaging, and even less likely.
Protecting what matters most.
An accident occurs. Various crumple zones keep the cabin isolated, while an advanced airbag system offers protection to the head, knees and more. Side impact airbags deploy in the rear, and even the seatbelts themselves are reinforced with airbags to distribute force and protect the ribcage. Protecting drivers and passengers has always been our priority, and with every innovation, that legacy continues.
Preventing accidents before they happen.
To this day, breakthroughs continue in the world of safety. Here are some of the most advanced safety features in the Mercedes‑Benz lineup

Accident Investigation
Just a few pieces of data can mean the difference between a collision and close call. That’s why we created the Mercedes-Benz Accident Investigation team, a special unit in Stuttgart, Germany dedicated to gathering and evaluating information that has the potential to save lives across the world.
From impact speed to collision angles, the data collected at the scene informs our ongoing improvement of safety features, and has led to the development of groundbreaking technology like ATTENTION ASSIST and DISTRONIC PLUS with PRE-SAFE® Brake.
Lighting Technology

PRE-SAFE closes the side windows when the system’s sensors detect side movements that suggest a possible rollover. A small gap is left near the fully closed position. Seat and head restraint
Distronic Adaptive Cruise Control is no substitute for active driving involvement. It does not react to stationary objects, nor recognize or predict the curvature and lane layout of the road or the movement of the vehicles ahead. It is the driver’s responsibility at all times to be attentive to traffic and road conditions, and to provide the steering, braking and other driving inputs necessary to retain control of the vehicle. After braking the car for stopped traffic ahead, the system resumes automatically only if traffic pauses for less than 3 seconds. Drivers are cautioned not to wait for the DISTRONIC Proximity Warning System before braking, as that may not afford sufficient time and distance to brake safety. Braking effectiveness also depends on proper brake maintenance, and tire and road conditions.
Night View Assist PLUS does not replace the use of headlamps and must not be used as the primary visual source for the driver.
Mercedes-Benz Pre-Safe Functions Limited See Owner’s Operator’s Manual
Road safety has always been a concern for both passengers and car drivers; therefore Mercedes Benz has developed and installed new high-tech protective system named as “PRESAFE system” in all its new vehicles to ensure maximum protection for both the pedestrians and drivers. MB has either installed it as a standard or made available with the Mercedes-Benz C-Class W205 Saloon Sedan S205 Estate A205 Convertible Cabriolet C205 Coupe, Mercedes-Benz E-Class, Mercedes-Benz S-Class, Mercedes-Benz CLA, Mercedes-Benz CLS, Mercedes-Benz GLA, Mercedes-Benz GLC X253 Hatchback C253 Coupe SUV, Mercedes-Benz GLE MLW166 C292 SUV , Mercedes-Benz GLS X164 X166, Mercedes-Benz SLC, and Mercedes-Benz SL models. This PRESAFE function is aimed at proactively preventing any accident or collision that might occur on the road.
What does a PRESAFE function mean?
As the name implies, PRESAFE function is all
How does PRESAFE function work?
This advanced safety system uses a variety of radar sensors located under front bumper and Mercedes-Benz’s star sign, supplemental brake assist plus and the PRESAFE brake with pedestrian recognition. Using the pedestrian recognition feature, the PRESAFE brake takes on a new dimension. A stereo camera and a system of long, medium and short range radar monitor the area in front of the vehicle. The control unit combines this information and processes it to ensure the early detection of road users in the lane analyzed.
At the same time, this data is used to calculate the chances of collision, and if any such risk is identified, the PRESAFE brake feature engages the PRESAFE system to initiate up to 40% braking power and provides visual and audible warnings at first, which a driver must pay attention to. If the driver responds and breaks the brake assist plus, it ensures that the optimal 100% brake is instantly applied even if the pedal has been pressed too lightly. In critical situations, if the driver fails to respond and does not take any action, autonomous full braking may take place as necessary to help reduce the intensity of a collision.
The PRESAFE brake with pedestrian recognition can prevent collisions with people up to approx. 30 miles per hour. Moreover, the severity of the accident can be reduced significantly at up to approx. 45 miles per hour.
What does PRESAFE system do?
To reduce the effects of an accident, the autonomous PRESAFE system immediately activates its features which include:
- Front head restraints and passenger seats adjustment for maximum protection of passenger injuries in an event of crash.
- The windows and sunroof closes if a rollover is possible to prevent debris like broken glass and vehicle parts from entering the cabin.
- Tension in the front safety belts is increased to protect occupants from injury or reduce the severity of the injuries.
- In select models, PRESAFE® Sound emits a tone that causes a reaction in the inner ear to protect the eardrum from damage.
This all is done to better prepare the occupants for more effective results from the restraint systems.
What causes PRESAFE function limited message appears?
When you start your car, and your vehicle displays “Pre Safe Functions Limited,” message on the vehicle’s information panel located just behind the steering wheel or main dashboard, it means your Mercedes-Benz may need an adjustment or a cleaning service for its PRESAFE system sensor. This message is reportedly seems to appear when the vehicle is used in torrential rains, snowy or dusty road conditions where the dust, rain or snow may get into the sensors and they wouldn’t be receiving signals, so just warn you. In such situations, the sensors may be dirty or clogged with snow, ice or dust hampering the performance of the PRESAFE functions.
If you have cleaned your radar sensors and Presafe functions limited warning message still being displayed it is most likely that that there is something bad with one of the radar sensors.
Visit mechanic shop or do it yourself at home – remove bumper inspect radars mounted on the front of the car, all depends on the car’s specification how many and which types radars you have.
Check for water or moisture damage, wiring damage, smell connector plug if there is bad smell that or any signs of water / moisture it is definitely that radar needs to be replaced to fix this warning message.
Unfortunately, the owner’s manual is not too clear on this message and asks you to visit a qualified specialist workshop. So, when this happens to your Mercedes, all you can do on your own is to check the sensors and set them clean. Doing this, should clear out the error message.
