PRE-SAFE
®
may take the following measures
in these situations:
R it tensions the front seat belts.
R on vehicles with memory functions*: it
adjusts the front-passenger seat if this is in
an unfavourable position.
R on vehicles with multicontour seat* or
active multicontour seat*: it increases the
air pressure in the seat side cushions and
the backrest side cushions.
R if the vehicle skids, it closes the sliding/
tilting sunroof* or panorama sliding sun-
roof* and the side windows so that only a
small gap remains.
if the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. You can then reverse
all settings made by PRE-SAFE ®
. On vehicles
with a multi-contour seat* or an active multi-
contour seat*, the air pressure in the side
bolsters is then reduced again.
If the seat belts are not released:
X Move the backrest or the seat back slightly
until the belt tension is reduced.
The locking mechanism releases. G
Risk of injury
When adjusting the seat, make sure that
nobody can become trapped.
! Make sure that there are no objects in the
footwell or behind the seats when adjusting
the seats. You could otherwise damage the
seats and the objects. NECK-PRO head restraints
NECK-PRO head restraints are designed to
increase protection to the driver's and front-
passenger's head and neck. To this end, the
head restraints on the driver's and front-
passenger seats are moved forwards and
upwards in the event of a rear-end collision of
a certain severity when viewed in the direc- tion of travel. This provides better head sup-
port. G
Risk of injury
Head restraint covers prevent the NECK-PRO
head restraints from triggering correctly. Con-
sequently, the NECK-PRO head restraints
cannot provide the intended level of protec-
tion. Do not use head restraint covers.
If the NECK-PRO head restraints are triggered
in an accident, you must reset the head
restraints on the driver's and front-passenger
seats (Y page 303). Head restraints that have
been triggered are tilted forwards. Children in the vehicle
If a child is travelling in your vehicle, secure
the child using a child restraint system which
is appropriate to the size and age of the child
and is recommended for Mercedes-Benz
vehicles. You should fit the restraint system
to a suitable rear seat. You can also secure
the child on the integrated child seat*
(Y page 53). Ensure that the child is secured
throughout the trip.
You can obtain information about the correct
child restraint system from any Mercedes-
Benz Service Centre.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems.
Information about this can be obtained
from any Mercedes-Benz Service Centre. G
Risk of injury
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system. Children could injure them-
selves on parts of the vehicle. They could also
be seriously or even fatally injured by pro-
longed exposure to extreme heat or cold.
Do not expose the child restraint system to
direct sunlight. Parts of the child restraint sys-
tem could heat up and the child could burn
herself/himself on them. Occupant safety

Make sure that the exterior mirrors are
always folded out fully while the vehicle is
in motion; otherwise, they may vibrate.
Resetting the exterior mirrors If the battery has been disconnected or has
become discharged, the exterior mirrors
must be reset. Otherwise, the exterior mirrors
will not fold in when you select the "Fold in
mirrors when locking" function in the on-
board computer (Y page 136).
X Make sure that the key is in position 1in
the ignition lock.
X Briefly press button :.
Automatically folding exterior mirrors
in or out* If the "Fold in mirrors when locking" function
is activated in the on-board computer
(Y
page 136):
R the exterior mirrors fold in automatically as
soon as you lock the vehicle from the out-
side.
R the exterior mirrors fold out again automat-
ically as soon as you unlock the vehicle and
then open the driver's or front-passenger
door.
i If you have activated this function and fold
in the exterior mirrors using button :, they
will not be folded out automatically. You
can only fold out the exterior mirrors again
using button :. Automatic anti-dazzle mirrors*
The rear-view mirror and the exterior mirror
on the driver's side automatically go into anti-
dazzle mode if the ignition is switched on and
incident light from headlamps strikes the sen-
sor in the rear-view mirror.
The mirrors do not go into anti-dazzle mode if
reverse gear is engaged or the interior lighting
is switched on. G
Risk of accident
If the incident light from headlamps cannot
strike the sensor in the rear-view mirror, for
instance, when the rear window blind* is
extended, the mirror's automatic anti-dazzle
function will not operate.
Incident light could then dazzle you. This may
distract you from the traffic conditions, and
you may, thereby, cause an accident. In this
case, adjust the rear-view mirror manually. Memory functions*
Storing settings
Using the memory button you can store up to
three different settings, e. g. for three differ-
ent people.
The following settings are stored as a single
memory preset:
R position of the seat, backrest and head
restraint
R active multicontour seat*: dynamic func-
tion level
R driver's side: steering wheel position
R driver's side: position of the exterior mir-
rors on the driver's and front-passenger
sides G
Risk of injury
The memory function can still be used when
the key has been removed. For this reason,
children should never be left unsupervised in
the vehicle. Otherwise, they could become
trapped when moving the seat or the steering
wheel. G
Risk of accident
Only use the memory function on the driver’s
side when the vehicle is stationary. Other-
wise, you could be distracted from the traffic
conditions by the steering wheel and seat
moving of their own accord, and as a result
cause an accident. Memory functions*
