BruNo

if its an 06 us model, how do i know if its presafe equipped?

US model MLs dont have Presafe. Presafe equipped vehicles have reversible seat belt tensioners. Make a fast curve at the limit and the seat belt pulls you into the seat.

Wolfgang,

I dont know if it is the full presafe system but look at page 18 and 19 of the USA ML brochure it mentions the safety systems

It has PreSafe. It is not crippled in any way. In the event of an accident the windows, sunroof will close, and the seats will return to an upright position and cushion you for the impending crash, along with the seat belt tensioners pulling you back into your seat.

The US M-Class does not have Presafe. In the European M-Class Presafe is optional. Code 299 for EU335.

Here's a picture of the reversible seat belt retractor used in the European MLs:

here is some of what is on Page 19 of the 2007 USA Brochure verbatim.

rollover sensor
If the M-Class senses certain rollovers, it will
automatically deploy the seat-belt Emergency
Tensioning Devices (ETDs) to help reduce
occupant movement and, if deemed necessary,
inflate the Window Curtain Air Bags


Integrated Restraint System
Every M-Class offers the comprehensive protection of eight standard air bags,5
including adaptive dual-stage air bags for the driver and front passenger, front-seat
mounted side-impact air bags, rear side-impact air bags and, for all four outboard
occupants, Window Curtain Air Bags that help protect against head injury and
broken glass in a side impact exceeding a preset threshold, or in certain rollovers.
Active Front Head Restraints also work to help prevent whiplash-type neck
injuries in the event of a rear-end collision exceeding a preset threshold.
Advanced front-impact protection

The front-end structure of the M-Class incorporates upper and
lower elements to provide two levels of energy management in
frontal impacts with a variety of vehicle sizes. Features such as
an ellipsoidal front bulkhead and reinforced wheel arches help
channel some of the force from a frontal impact over, under and
around the passenger cabin.

Doesn't mention Presafe.

Here's a writeup with pictures how the ETDs work. For Presafe the car also has to have reversible belt tensioners.
