Unfastening of seat belts
Push the release button (3) in the belt buckle (2). Allow
the retractor to completely rewind the seat belt by
guiding the latch plate (1).
Operation
The inertia reel stops the belt from unwinding during
sudden vehicle stops or when quickly pulling on the
belt. The locking function of the reel may be checked by
quickly pulling out the belt.

Wa r n i n g !
USE SEAT BELTS PROPERLY.• Seat belts can only work when used properly.
Never wear seat belts in any other way than as
described in this section, as that could result
in serious injuries in case of an accident.• Each occupant should wear their seat belt at all
times, because seat belts help reduce the
likelihood of and potential severity of injuries
in accidents, including rollovers. The
integrated restraint system includes “SRS”
(driver airbag, front passenger airbag, door
mounted side impact airbags), “ETR” (seat belt
emergency tensioning retractors), and front
seat knee bolsters. The system is designed to
enhance the protection offered to properly
belted occupants in certain frontal (front
airbags) and side (side impact airbags) impacts
which exceed preset deployment thresholds. • Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys etc., as these might
cause injuries.

Te ch n ica l

cluster displayPractical hints Car care IndexSafety guidelines for the seat belt,
emergency tensioning retractor and airbag
Wa r n i n g !
Accident research shows that the safest place for
children in an automobile is in the rear seat.
Should you choose to place a child 12 years old or
under in the front passenger seat of your vehicle,
you m ust properly use a BabySmart
TM child
restraint which will turn off the passenger side
front airbag. BabySmart
TM will not, however, turn
off the passenger’s side impact airbag.
It should be noted however that there is a
possibility for a side airbag related injury if
occupants, especially children, are not properly
seated or restrained when next to a side airbag
which needs to deploy rapidly in a side impact in
order to do its job.To help avoid the possibility of injury, please follow
these guidelines: (1) occupants, especially
children, should never place their bodies or lean
their heads in the area of the door where the side
airbag inflates. This could result in serious
injuries or death should the side airbag be
activated; (2) always sit upright, properly use the
seat belts and use an appropriately sized infant or
child restraint system for all children 12 years old
or under; and (3) always wear seat belts properly.
Wa r n i n g !
• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Center.• Do not pass belts over sharp edges.• Do not make any modification that could
change the effectiveness of the belts.• Airbags and ETR’s are designed to function on
a one-time-only basis. An airbag or emergency
tensioning retractor (ETR) that was activated
must be replaced.
