WARNING
If the 00730074 indicator lamp does not illuminate or remains out with the weight of a typical 12-
month-old child in a standard child restraint or less, or is unoccupied, on the front-passenger seat, do not transport a child on the front-passenger seat until the system has been repaired. PRE-SAFE
®
(anticipatory occupant
protection system)
Introduction PRE-SAFE
®
takes preemptive measures to
protect occupants in certain hazardous sit-
uations.
Important safety notes !
Make sure that there are no objects in the
footwell under or behind the seats when
moving the seats back. There is a risk that
the seats and/or the objects could be dam-
aged.
Despite your vehicle being equipped with the PRE-SAFE ®
system, the possibility of per-
sonal injuries occurring as a result of an acci-
dent cannot be eliminated.
Always adapt your driving style to suit the
prevailing road and weather conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
Function PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated.
R in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely.
R vehicles with the Driving Assistance
package: when BAS PLUS intervenes pow-
erfully or the radar sensor system detects
an imminent danger of collision in certain
situations. PRE-SAFE
®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R on vehicles with memory function for the
front-passenger seat: the front-passenger
seat is adjusted if it is in an unfavorable
position.
R if the vehicle skids, the side windows are
closed so that only a small gap remains.
The panorama roof with power tilt/sliding
panel is completely closed.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pre-tensioning. All settings made by
PRE-SAFE ®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
X Move the seat backrest or seat back
slightly when the vehicle is stationary.
The seat belt pre-tensioning is reduced and
the locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. More
information about seat-belt adjustment can
be found under "Seat-belt adjustment"
(Y page 56). NECK-PRO head restraints
The NECK-PRO head restraints increase pro-
tection for the driver's and front passenger's head and neck. In the event of a rear collision
of a certain severity, the NECK-PRO head
restraints on the driver's and the front-
passenger seats are moved forwards and
upwards. This provides better head support. 52

Adjust the seat and move the backrest to
an almost vertical position (Y page 94).
X Pull the seat belt smoothly through belt
sash guide 0043.
X Without twisting it, guide the shoulder sec-
tion of the seat belt across the middle of
your shoulder and the lap section across
your pelvis.
X Engage belt tongue 0044in buckle 0087.

(Y page 56).
X If necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body.
All seat belts except the driver's seat belt are
equipped with a special seat belt retractor to securely fasten child restraint systems in the
vehicle. For further information on special
seat belt retractors, see (Y page 61).
For more information about releasing the seat belt with release button 0085, see "Releasing
seat belts" (Y page 56).
Seat belt adjustment The seat-belt adjustment function adjusts the
driver's and front-passenger seat belt to the
upper body of the occupants. The belt strap is tightened slightly when:
R the belt tongue is engaged in the buckle
and
R the ignition is switched on
The seat-belt adjustment will apply a retrac-
tion force if any slack is detected between the occupant and the seat belt. Do not hold on tothe seat belt tightly while it is adjusting. You
can switch the seat-belt adjustment on and
off in the on-board computer (Y page 204).
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. More
information about PRE-SAFE ®
can be found in
the "PRE-SAFE ®
(anticipatory occupant pro-
tection system)" section (Y page 52).
Releasing seat belts X
Press release button 0085on belt buckle 0087.
X Guide belt tongue 0044to belt sash guide 0043.
i If you have guided the seat belt back, it is
turned 180°. This is necessary in order to
guarantee that the seat belt is not twisted
and that it is routed correctly when the belt is fastened.
! Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door, 56
