If you and/or your passenger release the
seat belt during driving, the seat belt
telltale 7 starts flashing and the
warning chime sounds as described before.
If the driver’s or the front passenger’s seat
belt remains unfastened after 60 seconds,
the warning chime stops sounding, the seat
belt telltale 7 stops flashing but
continues to be illuminated.
After a vehicle standstill, the warning chime
is reactivated and the seat belt telltale
7 is flashing again if the vehicle speed
once exceeds 15 mph (25 km/h).
The seat belt telltale 7 will only go out if
both the driver’s and the front passenger’s
seat belt (with the front passenger seat
occupied) are fastened, or the vehicle is
standing still and a front door is opened.
For more information, see “Practical hints”
( Y page 300).
Emergency Tensioning Device (ETD),
seat belt force limiter
The seat belts for the front seats and rear
outer seats are equipped with ETDs and seat
belt force limiters.
The ETDs are designed to activate in the
following cases:
R in frontal or rear-end impacts exceeding
the system’s preset deployment threshold
R in side impacts exceeding the system’s
preset deployment threshold on the far
side of the impact
R in certain vehicle rollovers
R if the restraint systems are operational and
functioning correctly, see “SRS indicator
lamp” ( Y page 36)
The ETDs for the front seats will only activate
if the front seat belts are fastened (latch plate
properly inserted into buckle).
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.
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.

Electronic Traction System
(ETS/4-ETS) GObserve Safety notes, see page 62.
The ETS (Electronic Traction System) and
4-ETS (four-wheel Electronic Traction
System, vehicles with 4MATIC only) are
components of the ESP ®
. The ETS/4-ETS
improves the vehicle’s ability to utilize
available traction, especially under slippery
road conditions by applying the brakes to a
spinning wheel. Vehicles with 4MATIC also
transfer more power to the wheel(s) with
traction.
When you switch off the ESP ®
, the
ETS/4-ETS is still enabled.
XIf conditions require, switch on the off-road
driving program ( Y page 155).
Off-road 4-ETS (vehicles with 4MATIC)

trailer stabilization
If the trailer you are towing should begin to
sway, the rig can only be stabilized by
immediately applying the brakes hard.
Steering during this maneuver will not help to
stabilize the rig.
The ESP ®
will assist you in such situations.
The ESP ®
recognizes when the trailer starts
swaying and will apply the brakes to reduce
the vehicle speed to a non-critical speed that
allows the vehicle-trailer combination to
stabilize.
The ESP ®
trailer stabilization is functional at
vehicle speeds above approximately 40 mph
(65 km/h) when the ESP ®
is switched on.
GWarning!
The system will not be able to assist when the
trailer jackknifes
R if the ESP ®
has switched off due to a
malfunction
R on wet or icy roads
R on roads with slippery surface
R in sand or gravel
Trailers with a high center of gravity may tip
over before the system recognizes swaying of
the trailer.
