The ETDs for the rear outer seats will activate
with or without the respective seat belts
fastened.
In an impact, the ETDs remove slack from the
seat belts in such a way that the seat belts fit
more snugly against the body. Seat belt force
limiters, when activated, are employed to
help reduce the peak force exerted by the
seat belts on occupants during a crash.
i The ETDs do not correct an incorrect seat
position or incorrectly worn seat belts.
The ETDs do not pull occupants back
toward the seat backrest.GWarning!
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-Benz Center.
The PRE-SAFE ®
system has electrically
operated reversible pre-tensioners that do
not require replacement after activation.
Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for the front
seats reduces the retracting force of the seat
belts when they are in normal use.
Preventive occupant safety (PRE-
SAFE ®
)
GWarning!
The PRE-SAFE ®
system is intended to reduce
the effects of an accident on vehicle
occupants who are wearing their seat belt
properly. Despite your vehicle being equipped
with the PRE-SAFE ®
system, the possibility of
personal injuries occurring as a result of an
accident cannot be eliminated. Therefore,
always drive carefully and adjust your driving
to the prevailing road, weather, and traffic
conditions.
The PRE-SAFE ®
system takes preventive
measures to better protect the occupants
from the possibility of personal injuries in the
following hazardous situations:
R emergency braking situations, e.g. if the
Brake Assist System (BAS) ( Y page 63) is
activated
or when
vehicles with DISTRONIC PLUS:
the BAS PLUS ( Y page 63) or the PRE-
SAFE ®
Brake ( Y page 69) is strongly
engaging
R when the radar sensors recognize the
immediate risk of collision in certain
situations (vehicles with DISTRONIC PLUS)
R critical dynamic driving situations, e.g.
when the vehicle has been caused to
understeer or oversteer because it has
exceeded its physical limitations or in case
of evasive steering maneuvers at speeds
above approximately 85 mph (140 km/h)
The PRE-SAFE ®
system takes the following
measures when it is activated:
R The front seat belts are pre-tensioned
automatically.
R If the front passenger seat is in an
unfavorable position, the seat will be
adjusted to a position that seeks to better
protect the occupant.
R The system increases the air pressure in
the air pockets (on the sides of the seat
cushion and backrest) of the drive-dynamic
multicontour front seats.
R If the vehicle is in a critical dynamic driving
situation, the door windows and the tilt/
sliding sunroof or panorama roof with tilt/
sliding panel also closes, except for a
minimal gap that remains open.
If the closing procedure of any of these
elements is blocked, it will stop and open
slightly.
Once the hazardous situation no longer exists
and an accident has been avoided, the PRE-
SAFE ®
system loosens the seat belt pre-Occupant safety53Safety and security212_AKB; 2; 41, en-USd2ureepe,Version: 2.11.8.12009-07-17T09:14:21+02:00 - Seite 53Z

Steering wheel
GObserve Safety notes, see page 93.XPosition steering wheel : properly
(Y page 93).
Make sure:
RYou can reach the steering wheel with your
arms slightly bent at the elbows.
RYou can move your legs freely.
RAll displays (including malfunction and
indicator lamps) on the instrument cluster
are clearly visible.
Seat belt
GObserve Safety notes, see page 48.XFasten and position your seat belt ;
correctly (Y page 50).
Make sure:
RThe seat belt is always fitted snugly.
RAdjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder.
RPlace the lap portion of the seat belt as low
as possible on your hips.
Seat and head restraint
GObserve Safety notes, see page 87.XPosition seat = and head restraint
properly. See (Y page 88) for seat and
head restraint adjustment.
Observe the following points:
RAlways be in a properly seated position.
RThe position should be as far rearward from
the front air bag in the steering wheel as
possible, while still permitting proper
operation of vehicle controls.
RAdjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely.
RThe seat must be adjusted so that you can
correctly fasten and position your seat belt.
RThe seat backrest must be in a position that
is as nearly upright as possible.
RAdjust the seat cushion so that the front
edge of the seat cushion lightly supports
your legs.
RAdjust the head restraint so that it is as
close to the head as possible and the
center of the head restraint supports the
back of the head at eye level.
RNever place hands under the seat or near
any moving parts while the seat is being
adjusted.
Occupant safety55Safety and security212_AKB; 2; 41, en-USd2ureepe,Version: 2.11.8.12009-07-17T09:14:21+02:00 - Seite 55Z

iIn winter operation, the maximum
effectiveness of most of the driving
systems described in this section is only
achieved with winter tires, or snow chains
as required.
Safety notesGWarning!
The following factors increase the risk of
accidents:
R Excessive speed, especially in turns
R Wet and slippery road surfaces
R Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or prevent
the natural laws of physics from acting on the
vehicle. They cannot increase braking or
steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires
or the traction afforded.
Only a safe, attentive, and skillful driver can
prevent accidents.
The capabilities of a vehicle equipped with the
driving safety systems described in this
section must never be exploited in a reckless
or dangerous manner which could jeopardize
the user’s safety or the safety of others.
Always adjust your driving style to the
prevailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
If a driving system malfunctions, other driving
safety systems may also switch off. Observe
indicator and warning lamps that may come
on as well as messages in the multifunction
display that may appear.
ABSGObserve Safety notes, see page 62.GWarning!
Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS
and significantly reduces braking
effectiveness.
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do not
lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of
approximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp ! in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal. The pulsation indicates that the
ABS is in the regulating mode.
XKeep firm and steady pressure on the brake
pedal while you feel the pulsation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to steer
the vehicle.
The pulsating brake pedal can be an
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving.
Emergency brake maneuver
XKeep continuous full pressure on the brake
pedal.62Driving safety systemsSafety and security

device could void the user’s authority to
operate the equipment.
Using the radar sensors, the PRE-SAFE ®
Brake detects obstacles that are in your
driving path for a sufficient period of time for
the system to recognize it. If you approach a
vehicle and the PRE-SAFE ®
Brake has
established that the distance to the vehicle
ahead at your current speed is so close that
the PRE-SAFE ®
Brake will not be capable of
slowing the vehicle sufficiently, the system
will initially warn you visually and acoustically.
If you do not apply the brakes yourself or
maneuver around a sensed obstacle, the
vehicle will brake lightly automatically. The
PRE-SAFE ®
system ( Y page 53) is activated
when the distance to the vehicle ahead atyour current speed is so close that the PRE-
SAFE ®
Brake will not be capable of slowing
the vehicle sufficiently.
When the danger of a collision still persists
and you do not brake or accelerate
significantly, the PRE-SAFE ®
Brake may
initiate full application of the brakes
automatically.GWarning!
The PRE-SAFE ®
Brake will only respond with
brake assistance if it has clearly detected an
object. Detection can be impeded by
R dirty or covered sensors
R snowfall or heavy rain
R disturbance from other radar sources
R strong radar reflection such as in parking
garages
The PRE-SAFE ®
Brake uses radar signals that
are not reflected well by narrow objects and
absorptive materials. For this reason the PRE-
SAFE ®
Brake will not react to persons,
animals, and approaching traffic or cross-
traffic.
The PRE-SAFE ®
Brake may not detect narrow
vehicles driving in front of you, such as
motorcycles and vehicles driving offset from
your vehicle center.
GWarning!
Depending on the vehicle speed, the
PRE-SAFE ®
Brake brakes your vehicle with a
maximum of 13 ft/s 2
(4 m/s 2
) before a
possible hard stop. This corresponds to about
40% of the maximum deceleration ability of
your vehicle. The driver must apply the brakes
additionally in order to prevent a collision. The
self-acting hard stop will be initiated when the
imminent danger of a collision exists, e.g.
when an evasive driving maneuver cannot
avoid an accident.
