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 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.
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 vehicles with the Driving Assistance pack-
age: when a driver assistance system inter-
venes powerfully or the radar sensor sys-
tem detects an imminent danger of colli-
sion 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 if the vehicle skids, the sliding sunroof and
the side windows are closed so that only a
small gap remains. The panorama sliding
sunroof is completely closed.
R vehicles with the memory function for the
front-passenger seat: 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 belt pre-tensioning is not reduced:
X Move the seat backrest or seat back
slightly 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. You
will find information on the convenience func-
tion under "Belt adjustment" (Y page 50). PRE-SAFE

PLUS is able to detect that a head-on or rear-
end collision is imminent. In certain hazard-
ous situations, PRE-SAFE ®
PLUS takes pre-
emptive measures to protect the vehicle
occupants.
Important safety notes The intervention of PRE-SAFE
®
PLUS cannot
prevent an imminent collision.
The driver is not warned when PRE-SAFE ®
PLUS intervenes.
PRE-SAFE ®
PLUS does not intervene:
R if the vehicle is reversing
R when the vehicle is towing a trailer and
there is a risk of a rear-end collision

Always observe the information on suitable
positioning of the child restraint system
(Y page 68) in addition to the child restraint
system manufacturer's installation and oper- ating instructions.
Forward-facing child restraint system If it is absolutely necessary to fit a forward-
facing child restraint system to the front-
passenger seat, always move the front-
passenger seat as far back as possible. Fully
retract the seat cushion length. The entire
base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the child
restraint system must, as far as possible, be
resting on the backrest of the front-
passenger seat. The child restraint system
must not touch the roof or be put under strain
by the head restraint. Adjust the angle of the seat backrest and the head restraint position
accordingly. Always make sure that the shoul- der belt strap is correctly routed from the
vehicle belt outlet to the shoulder belt guide
on the child restraint system. The shoulder
belt strap must be routed forwards and down-
wards from the vehicle belt outlet. If neces-
sary, adjust the vehicle belt outlet and the
front-passenger seat accordingly.
Always observe the information on suitable
positioning of the child restraint system
(Y page 68) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions. Suitable positioning of the child
restraint system
Introduction Only child restraint systems which are
approved in accordance with the ECE stand-
ard ECE R44 are permitted for use in the vehi- cle.
For certain child restraint systems in weight
categories II or III, this can mean that the area
of use is restricted. The maximum size setting of the child restraint system is not possible
due to possible contact with the roof.
"Universal" category child restraint systems
can be recognised by their orange approval
label and the text "Universal".
Example: approval label on the child restraint sys-
tem
"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 belt-secured child
restraint systems" or "Suitability of the seats
for attaching an ISOFIX child restraint sys-
tem".
Semi-universal child restraint systems are
indicated by the text "Semi-universal" on the
approval label. These can be used if the vehi- cle and the seat are listed in the child restraintsystem manufacturer's vehicle model list. For
more information, contact the child restraint
system manufacturer or visit their website.
Child restraint system on the front-
passenger seat – if it is absolutely necessary
to secure a child in a child restraint system on the front-passenger seat:
X Always pay attention to the instructions
under "Child restraint system on the front-
passenger seat" (Y page 66).
There you will find instructions on how to
correctly route the shoulder belt strap from the vehicle belt outlet to the shoulder belt 68

guide on the child restraint system
(Y
page 68).
X Move the front-passenger seat as far back
as possible and fully retract the seat cush-
ion length.
X Move the backrest to an almost vertical
position.
The entire base of the child restraint sys-
tem must always rest on the seat cushion of the front-passenger seat. The backrest of
the forward-facing child restraint system
must, as far as possible, be resting on the
backrest of the front-passenger seat. The
child restraint system must not touch the
roof or be put under strain by the head
restraint. Adjust the angle of the seat back- rest and the head restraint position accord-
ingly. Also observe the child restraint sys-
tem manufacturer's installation instruc-
tions.
X Move the seat cushion angle to the highest,
most vertical position.
Suitability of the seats for attaching
belt-secured child restraint systems If you use a baby car seat of category 0 or 0+
or a rearward-facing child restraint system of category I on a rear seat, you must adjust the
driver's or front-passenger seat so that the
seat does not touch the child restraint sys-
tem.
If you use a forward-facing child restraint sys-
tem from category I, you must, where possi- ble, dismantle the head restraint of the
respective seat (Y page 122). The backrest of
the child restraint system must, as far as pos- sible, lie flat against the backrest of the seat.
Always observe the notes in the "Child
restraint system" section (Y page 64) and the
child restraint system manufacturer's instal-
lation instructions.
When you remove the child restraint system,
you must immediately replace the head
restraint (Y page 121). All vehicle occupants
must adjust their head restraints correctly
before beginning the journey. Legend for the table:
