PRE-SAFE can be activated and automatically respond about 200ms ahead of the accident to ensure safety belt and airbag get the best effects in crush.

Once potential risks are identified, such as over-steering, under-steering, emergency steering, unexpected or sudden brake etc., and take the proactive measures by automatically closing the sunroof and side windows, tightening the safety belt, and adjusting the seats to proper position, ensuring to eliminate impact on heads and necks.

When risk is eliminated, PRE-SAFE will automatically restore the previous measures into standby status by opening side windows, releasing the safety belt, and resetting the seats to the normal positions.

The standard-equipped attention assist system will be automatically activated at the speed of 80-180 km/h. This system, based on over 70 pre-set programs, can consistently monitor the driver and automatically identify whether the driver is fatigue or distracted. Once the system detects the driver's condition will reduce the driving safety, it will trigger the audio alarm warning and remind you: "Time for a break".

The forward-looking and innovative technology developed by Mercedes-Benz makes the new long wheelbase E-Class a one-of-a-kind "sensing" feature to ensure driving safety.

Based on the vehicle passive safety, the new long wheelbase E-Class continues to provide users with more extensive safety equipments.

Once accident happens, nine airbags will expand within several milliseconds including two adaptive airbags (driver and co-driver), one knee bag (driver), four sidebags in front and rear backrests and two big windowbags extending from A-pillar to C-pillar in crush.
