PRE-SAFE
®
(preventative occupant
protection)
i AMG vehicles do not include the PRE-
SAFE ®
system.
All vehicles (except AMG vehicles): the
PRE-SAFE ®
system is only available in
vehicles with DISTRONIC PLUS. G
WARNING
Make sure that nobody can become trapped
as you adjust the seat. G
WARNING
The PRE-SAFE ®
system reduces the impact of
an accident on vehicle occupants, as long as
their seat belts have been fastened correctly.
Although your vehicle is equipped with a PRE-
SAFE ®
system, the possibility of injury in the
event of an accident cannot be ruled out. You
should therefore always drive carefully and
adapt your driving style to the prevailing road,
weather and traffic conditions.
! Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
PRE-SAFE ®
takes preemptive measures to
protect occupants in certain hazardous
situations.
PRE-SAFE ®
intervenes:
R if BAS intervenes, e.g. in emergency
braking situations.
R when BAS PLUS intervenes powerfully on
vehicles with DISTRONIC PLUS.
R when the radar sensor system detects an
imminent danger of collision in certain
situations on vehicles with DISTRONIC
PLUS.
R in critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely. PRE-SAFE
®
takes the following measures
depending on the hazardous situation
detected:
R the 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 almost completely.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. 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.
The belt pretensioning is reduced and the
locking mechanism is released.

Important safety notes G
WARNING
Do not secure any objects (e.g. coat hangers)
on the NECK-PRO head restraints. Otherwise,
the NECK-PRO head restraints may not
function properly, or in the event of a rear-end
collision may not be able offer the level of
protection they are designed to provide. G
WARNING
Seat or head restraint covers can cause a
malfunction when the NECK-PRO head
restraints are activated or when the side
impact air bags are deployed, or they can
prevent this completely. The NECK-PRO head
restraints or side impact air bags can
therefore not provide the intended protection.
Do not use any seat or head restraint covers. 50

Belt warning for the driver and front
passenger Regardless of whether the driver's and front-
passenger seat belts have already been
fastened, the 0011seat belt warning lamp
lights up for six seconds each time the engine
is started. It then goes out if the driver and
the frontp assenger have fastened their seat
belts.
If the driver's seat belt is no tfastened when
the engine is started, an additional warning
tone will sound. The warning tone goes out
after approximately six seconds or once the
driver's seat belt is fastened.
If after six seconds the driver or front
passenger have no tfastened their seat belts
and the doors are closed, the 0011seat belt
warning lamp lights up:
R until the driver's or fron tpassenger's seat
belt is fastened
R if a vehicle speed of 15 mph (25 km/h) is
exceeded, a warning tone also sounds with
increasing intensity for a maximum of
60 seconds or until the driver or front
passenger have fastened their seat belts. If the driver/front passenger unfasten their
seat belt while the vehicle is in motion, the
0011
seat belt warning lamp lights up and a
warning tone sounds again.
The warning tone ceases eve nifthe driver or
front passenger have still not fastened their
seat belt after 60 seconds. The 0011seat belt
warning lamp stops flashing but remains
illuminated.
After the vehicle comes to a standstill, the
warning tone is reactivated and the 0011seat
belt warning lamp flashes again if the vehicle
speed again exceeds 15 mph (25 km/h).
The 0011 seat belt warning lamp only goes
out if:
R both the driver and the front passenger
have fastened their seat belts.
or
R the vehicle is stationary and a door is open.

Emergency Tensioning Devices, belt
force limiters G
WARNING
Pyrotechnic ETDs that were activated must be
replaced.
For your safety, when disposing of the
pyrotechnic ETDs always follow our safety
instructions. These are available at any
authorized Mercedes-Ben zCenter.
! If the front-passenger seat is not
occupied, do not engage the seat belt
tongue in the buckle on the front-
passenger seat. Otherwise, the Emergency
Tensioning Device could be triggered in the
event of an accident.
The seat belts are equipped with Emergency
Tensioning Devices and belt force limiters.
The ETDs tighten the seat belts in an accident,
pulling them close against the body. Occupant safety
55Safety Z

The ETDs do not correct incorrect seat
positions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
When triggered, seat belt force limiters help
to reduce the peak force exerted by the seat
belt on the vehicle occupant.
The seat belt force limiters are synchronized
with the fronta
ir bags, which take on a part
of the deceleration force. Thus, the force
exerted on the occupant is distributed over a
greater area.
The ETDs can only be activated when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 39).
R the belt tongue is engaged in the buckle on
each of the three-point seat belts.
The ETDs are triggered depending on the type
and severity of an accident:
R if, in the event of a head-on or rear-end
collision, the vehicle decelerates or
accelerates rapidly in a longitudinal
direction during the initial stages of the
impact
R if, in the even tofaside impact, on the side
opposite the impact the vehicle
decelerates or accelerates rapidly in a
lateral direction
R if, in certain situations where the vehicle
overturns, the system determines that it
can provide additional protection
If the ETDs are deployed, you will hear a bang,
and a small amount of powder may also be
released.O nly in rare cases will the bang
affect your hearing .The powder that is
released generally does not constitute a
health hazard. The 001BSRS warning lamp
lights up. Child restraint systems
Important safety notes
G
WARNING
Children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child.
The infant or child restraint system must be
correctly secured using the vehicle's seat belt
in complete accordance with the child seat
manufacturer's instructions.
Occupants, in particular children, must sit as
upright as possible, fasten the seat belt
correctly and use a suitable infant restraint
system, child restraint system or booster seat
suitable for the size and weight of the child.
Children can be seriously or even fatally
injured by an air bag deploying. Observe the
following information:
R Your vehicle is equipped with air bag
technology designed to deactivate the
front-passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the passenger seat.
R Ac hild in a rearward-facing child restraint
system on the front-passenger seat could
be seriously injured or even killed if the
front-passenger air bag inflates in a
collision despite the air bag technology
installed in your vehicle, which could occur
under some circumstances.
R If you install a rearward-facing child
restraint on the front-passenger seat, make
sure that the 0017PASSENGER AIR BAG
OFF indicator lamp is illuminated,
indicating that the front-passenger front air
bag is deactivated. Should the 0017
PASSENGER AIR BAG OFF indicator lamp
not illuminate or go out while a rearward-
facing child restraint system is installed,
please check installation. Periodically 56

0017PASSENGER AIR BAG OFF
indicator lamp while driving to make sure it
is illuminated. If the 0017PASSENGER AIR
BAG OFF indicator lamp goes ou tor
remains out, do not transport a child on the
front-passenge rseat.
R Ac hild in a rearward-facing child restraint
system on the front-passenger seat can be
seriously injured or even killed if the front-
passenger air bag is deployed.
R When securing a child in achild restraint
system on the front-passenger seat, you
must:
- move the front-passenger seat as far
back as possible
- use a child restraint system that is
suitable for the age, size and weight of
the child
- observe the manufacturer's installation
instructions in order to install and secure
the child restraint system correctly.
R For children larger than the typical 12-
month-old child, the front-passenger front
air bag may or may not be activated. G
WARNING
Infants and small children should never share
a seat belt with another occupant. In the event
of an accident, they could be crushed
between the occupant and seat belt.
Ac hild's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
Children that are too large for a child restraint
must travel in seats using normal seat belts.
Position the shoulder belt across the chest
and shoulder, not face or neck.Ab ooster seat
may be necessary to achieve proper seat belt
positioning for children over 41 lb (18 kg) until
they reach a height where a lap-shoulder belt
fits properly without a booster.
When the child restraint is not in use, remove
it from the vehicle or secure it with the seat belt to prevent the child restraint from
becoming a projectile in the event of an
accident.
G
WARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. Achild's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could:
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
ignition lock or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned on these
parts. G
WARNING

Brake (Y page 65) Important safety notes
If you fail to adapt yourd riving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Always adapt yourd riving style to
suitt he prevailing road and weather
conditions and maintain asafe distance from
the vehicle in front. Drive carefully. i
The driving safety systems described only
work as effectively as possible when there
is adequate contact between the tires and
the road surface. Please pay special
attention to the note son tires,
recommended minimu mtire tread depths,
etc. (Y page 308).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible. ABS (Anti-lock Braking System)
Important safety notes i
Observe the "Importan tsafety notes"
sectio n(Ypage 59). G
WARNING
If ABSi s faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully. Have ABS checked
immediately at a qualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 244) and
display messages which may be shown in the
instrument cluster (Y page 212).
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
ABS works from a speed of about 5 mph
(8 km/h) upwards, regardless of road-surface
conditions. ABS works on slippery surfaces,
even if you only brake gently.
