66 Safety and SecurityOccupant safetyPreventive occupant safety (PRE-SAFE)
Your vehicle automatically takes preven-
tive measures to better protect the occu-
pants in the following hazardous
situations:

You execute an emergency braking ma-
neuver and the Brake Assist System
(page 78) is activated.


The PRE-SAFE system detects a critical
driving dynamics situation.In such cases, the following systems are
automatically activated:


The front seat belts are pre-tensioned.


If the front passenger seat or rear seats
are in an unfavorable position, they are
adjusted to a better position. Rear seat
a d j u s t m e n t o c c u r s o n l y i n v e h i c l e s w i t h
individual seats* in the rear.


The sliding/pop-up roof closes if the
vehicle is in a severe skid or is spin-
ning.
If the seat belts do not release:

Adjust the backrest or seat slightly to
the rear until the seat belt tension is di-
minished.
The locking mechanism releases.
Warning
G
The PRE-SAFE system is intended to reduce
the effects of an accident on properly seat
belted vehicle occupants. Despite having
the PRE-SAFE systems in your car, the pos-
sibility of injuries occurring as a result of an
accident cannot be totally eliminated.
Therefore you should always drive carefully
and adjust your driving to the prevailing
road, weather, and traffic conditions.
iThe PRE-SAFE systems are activated at
speeds exceeding 22 mph (35 km/h).
When the driving dynamic situation has
passed without an accident occurring,
the pre-tensioning on the seat belts is
deactivated.
You can then adjust the seats and the
sliding sunroof to their previous posi-
tion.

86 Controls in detailLocking and unlockingIn the “Controls in detail” section you will
find detailed information on how to oper-
ate the equipment installed on your vehi-
cle. If you are already familiar with the
basic functions of your vehicle, this section
will be of particular interest to you.
To quickly familiarize yourself with the ba-
sic functions of the vehicle, see “Getting
started” (
page 29). The corresponding
page numbers are given at the beginning of
each segment.
For information on locking and unlocking,
refer to the Getting started section on
(
page 30) and (
page 50).
Locking and unlockingSmartKey
Your vehicle comes supplied with two
SmartKeys with remote controls and a re-
movable mechanical key. The locking tabs
for the mechanical key portion of the two
SmartKeys are a different color to help dis-
tinguish each SmartKey unit.
The SmartKey provides an extended oper-
ating range. To prevent theft, however, it is
advisable to only unlock the vehicle when
you are in close proximity to it.
The SmartKey centrally locks and unlocks:

Locking and unlocking

Press switch2 in the trunk lid.
The trunk lid closes automatically and
the vehicle is locked. The turn signals
flash three times to confirm locking.Limiting opening height of trunk
You can limit the opening angle of the
trunk lid. The trunk lid then opens only to
approximately the height of the roof edge.
This can be useful when there is not
enough overhead clearance space, for ex-
ample. The trunk lid opening height can be
limited when transporting goods on a roof
rack (e.g. presence of an MB sport luggage
container). When activated, the trunk lid
opens to approximately the height of the
roof edge.

With the trunk lid closed, press the re-
mote control switch (
page 99) and
hold for at least five seconds.
Depending on its previous status, the
opening height restriction is then
switched either on or off.
iTo prevent a possible inadvertent lock-
out, the trunk lid will open automatical-
ly if a KEYLESS-GO card is recognized
in the area of the rear shelf or inside
the trunk.Warning!
G
Monitor the closing procedure carefully to
ensure that no one is in danger of being in-
jured. To prevent possible personal injury,
always keep hands and fingers away from
the trunk opening when closing the trunk.
Be especially careful when small children
are around. To stop the closing procedure,
press the trunk lid closing switch1 in the
trunk lid, the
Š
button on the SmartKey,
or the remote trunk lid switch (on driver’s
door control panel).
iIf the trunk lid comes into contact with
an object while closing (e.g. luggage
that has been piled too high), the clos-
ing procedure is stopped and the trunk
re-opens slightly.
The closing procedure can be stopped
at anytime by once again pressing the
closing switch in the trunk lid, the re-
mote control switch in the driver’s
door, or the
Š
button on the Smart-
Key.
