cluster displayPractical hints Car care Index Unfastening of seat belts
Push the release button (3) in the belt buckle (2).
Allow t he retractor to completely rewind t he 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, front
and rear door mounted side impact airbags,
head protection window curtain airbags for
side windows), “ETR” (seat belt emergency
tensioning retractors), and front seat knee
bolsters. The system is designed to enhance
the protection offered to properly belted
occ upan ts in c erta i n fron tal (front ai rb ags ) a nd
side (side impact and window curtain airbags)
impacts which exceed preset deployment
thresholds.

cluster displayPractical hints Car care Index Supplemental restraint system (SRS)
Airbags are intended as a supplement to seat belts.
Airbags alone cannot protect as well as airbags plus
seat belts in impacts for which the airbags were
designed to operate, and do not afford any protection
whatsoever in crashes for which the airbags are not
designed to deploy.
The SRS uses two crash severity levels (thresholds) to
activate either the Emergency Tensioning Retractor
(ETR) or front airbag or both. Activation depends on the
direction and severity of the impact exceeding the
preset thresholds and whether the seat belt is fastened.Seat belt fastened
•first threshold exceeded:
ETR activates
•second threshold exceeded:
airbag also activates
Seat belt not fastened
Front seats:
•first threshold exceeded:
airbag activates, but not ETR
Rear outer seats:
•first threshold exceeded:
ETR activates
Driver, front passenger and rear outer seat systems
operate independently of each other.

Emergency tensioning retractor (ETR)
The seat belts for the front and outer rear seats are
equipped with emergency tensioning retractors. These
tensioning retractors are located in each belt’s inertia
reel and become operationally ready with the electronic
key in steering lock position 1 or 2.
The emergency tensioning retractors are designed to
activate only when the seat belts are fastened during
frontal impacts exceeding the first threshold of the SRS
and in rear impacts exceeding a preset severity level.
They remove slack from the belts in such a way that the
seat belts fit more snugly against the body restricting
its forward movement as much as possible.In cases of other frontal impacts, angled impacts, roll-
overs, certain side impacts, or other accidents without
sufficient frontal or rear forces, the emergency
tensioning retractors will not be activated. The driver
and passengers will then be protected by the fastened
seat belts and inertia reel in the usual manner.
For seat belt and emergency tensioning retractor safety
guidelines, see page 75.
Note:
The front passenger ETR activates only if the front
passenger seat is occupied.
Heavy objects on the front passenger seat can appear to
the “SRS” to indicate the presence of an occupant in
that seat which causes the passenger front airbag to
deploy and the ETR to activate in a crash exceeding the
appropriate threshold.

cluster displayPractical hints Car care Index Airbags
1Driver airbag
2Front passenger airbagThe most effective occupant restraint system yet
developed for use in production vehicles is the seat belt.
In some cases, however, the protective effect of a seat
belt can be further enhanced by an airbag.
In conjunction with wearing the seat belts, the driver
and front passenger airbags can provide increased
protection for the driver and front passenger in certain
frontal impacts exceeding preset thresholds.
Door mounted side impact and head protection window
curtain airbags can provide increased protection to
belted outboard occupants on the impacted side of the
vehicle in side impacts exceeding its preset threshold.
The operational readiness of the airbag system is
verified by the indicator lamp “SRS” in the instrument
cluster when turning the electronic key in steering lock
to position 1 or 2. If no fault is detected, the lamp will go
out after approximately 4 seconds; after the lamp goes
out, the system continues to monitor the components
and circuitry of the airbag system and will indicate a
malfunction by coming on again. If the lamp does not
come on at all or if it fails to extinguish after
approximately 4 seconds or if it comes on thereafter, a
malfunction in the system has been detected.

The following system components are monitored or
undergo a selfcheck: crash-sensor(s), airbag ignition
circuits, front seat belt buckles, emergency tensioning
retractors, seat sensor.
Initially, when the electronic key is turned from
steering lock position 0 to position 1 or 2, malfunctions
in the crash-sensors are detected and indicated (the
“SRS” indicator lamp stays on longer than 4 seconds or
does not come on).
Have the system checked at your authorized
Mercedes-Benz Center immediately.
In the operational mode, after the indicator lamp has
gone out following the initial check, interruptions or
short circuits in the airbag ignition circuit and in the
driver and front passenger seat belt buckle harnesses,
and low voltage in the entire system are detected and
indicated.Note:
See page 236 for information on the Supplemental
Restraint System (SRS) indicator lamp.
Wa r n i n g !
In the event a malfunction of the “SRS” is indicated
as outlined above, the “SRS” may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have the
system checked; otherwise the “SRS” may not be
activated when needed in an accident, which could
result in serious or fatal injury, or it might deploy
unexpectedly and unnecessarily which could also
result in injury.
