Windowbags are deployed:
R at the start of an accident with a high rate of
lateral vehicle deceleration or acceleration,
e.g. in a side impact
R on the side on which an impact occurs
R on the driver's and the front-passenger's
side if the vehicle overturns and the system
determines that deployment can offer addi-
tional protection to that provided by the
seat belt
R independently of the use of the seat belt
R regardless of whether the front-passenger
seat is occupied
R independently of the front airbags PRE-SAFE
®
(anticipatory occupant
protection)
Introduction PRE-SAFE
®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
Important safety notes !
Make sure that there are no objects in the
footwell or behind the seats when moving
the seat back. There is a risk that the seats and/or the objects could be damaged.
Although your vehicle is equipped with a PRE-
SAFE ®
system, the possibility of injury in the
event of an accident cannot be ruled out.
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 on vehicles with DISTRONIC PLUS: when
adaptive Brake Assist intervenes power-
fully.
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R if the vehicle skids, the panorama sliding
sunroof and the side windows are closed so
that only a small gap remains.
R vehicles with the memory function: the
front-passenger seat is adjusted if it is in an
unfavourable position.
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 belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
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 48). Seat belts
Important safety notes G
WARNING
A seat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot provide the intended 46
Occupant safetySafety

pants in the event of an accident. This
reduces the risk of vehicle occupants coming
into contact with parts of the vehicle interior.
Fastening seat belts X
Adjust the seat and move the backrest to
an almost vertical position (Y page 98).
X Pull the seat belt smoothly from belt sash
guide :.
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 ;in buckle =.
Seat belt adjustment: if necessary, the driv-
er's and front-passenger seat belts auto-
matically adjust to the upper body
(Y page 48).
X If necessary, adjust the seat belt to the
appropriate height (Y page 48).
X If necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body.
Information on releasing the seat belt with
release button ?(Ypage 49). 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 you engage the belt tongue in the belt
buckle and you then turn the key to position
2 in the ignition lock.
R the key is in position 2in the ignition lock
and you then engage the belt tongue in the buckle.
The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the occupant and the seat belt. Do
not hold on to the seat belt tightly while it is
adjusting. You can switch the seat-belt
adjustment on and off in the on-board com-
puter (Y page 230).
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 ®
(preventative occupant pro-
tection)" section (Y page 46).
Belt height adjustment You can adjust the belt height for the front
seats. Adjust the belt to a height that allows
the upper part of the seat belt to be routed
across the centre of your shoulder. 48

If you use a baby car seat from category 0 or 0+ or a rearward-facing child restraint system from category I
on a rear seat, you must adjust the driver's or front-passenger seat so that the seat does not touch the
rearward-facing child restraint.
2 Vehicles with automatic child seat recognition in the front-passenger seat: a child restraint system from the
"Universal" category with a transponder for automatic child seat recognition must be fitted. The PASSENGER AIRBAG OFF indicator lamp must be lit.
3 Move the front-passenger seat as far back as possible. If you secure a child in a forward-facing child restraint
system on the front-passenger seat, ensure that the shoulder belt strap from the belt outlet on the vehicle is
routed towards the front to the shoulder belt guide on the child restraint system. Set the belt height adjust-
ment so that the belt strap is routed towards the front along the bottom. Move the front-passenger seat to the highest position and move the backrest to an almost vertical position. When doing so, ensure that the com-plete surface of the child restraint system rests against the backrest of the front-passenger seat and that the
child restraint system does not touch the roof. To do so, you may have to adjust the backrest down a little. For seats with electrical adjustment, the seat cushion angle must be set to the highest and most upright position.

Example: approval label on the child restraint system
"Universal" category child restraint systems can be recognised by their orange approval label and the text "Universal".
"Universal" category child restraint systems can be used on the seats indicated with U, UF or
IUF according to the tables "Suitability of the seats for attaching belted child restraint systems"
or "Suitability of the seats for attaching an ISOFIX child restraint system".
Semi-universal child restraint systems are indicated by the text "Semi-universal" on the
approval label. These can be used if the vehicle and the seat are listed in the child restraint
system manufacturer's vehicle model list. For more information, contact the child restraint
system manufacturer or visit their website.
Suitability of the seats for attaching ISOFIX child restraint systems
1 If you use a baby car seat from category 0 or 0+ or a rearward-facing child restraint system from category I
on a rear seat, you must adjust the driver's or front-passenger seat so that the seat does not touch the
rearward-facing child restraint.
3 Move the front-passenger seat as far back as possible. If you secure a child in a forward-facing child restraint
system on the front-passenger seat, ensure that the shoulder belt strap from the belt outlet on the vehicle is routed towards the front to the shoulder belt guide on the child restraint system. Set the belt height adjust-
ment so that the belt strap is routed towards the front along the bottom. Move the front-passenger seat to the
highest position and move the backrest to an almost vertical position. When doing so, ensure that the com- plete surface of the child restraint system rests against the backrest of the front-passenger seat and that thechild restraint system does not touch the roof. To do so, you may have to adjust the backrest down a little. For seats with electrical adjustment, the seat cushion angle must be set to the highest and most upright position.
5 For certain child restraint systems in this weight category, this can mean that the area of use is restricted as
the maximum size setting of the child restraint system is not possible due to possible contact with the roof. 58
