Operation of seat belts
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.
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).
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 and front passenger airbag) and
“ETR” (seat belt emergency tensioning
retractors for the driver’s seat, passenger’s seat
and rear outboard passenger seats). The
system is designed to enhance the protection
offered to properly belted occupants in certain
frontal (front airbags) impacts which exceed
preset deployment thresholds.

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 activatesSeat belt not fastened
Front seats:
•first threshold exceeded:
airbag activates, but not ETR
Rear outer seats:
•first threshold exceeded:
ETR activates
Notes:
Driver, front passenger and rear outer seat systems
operate independently of each other.
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 in a crash exceeding the appropriate threshold.

65 Restraint systems
Te ch n i c a l

cluster displayPractical hints Car care Index Emergency tensioning retractor (ETR)
The seat belts for the front seats and outboard
passenger seats are equipped with emergency
tensioning retractors. These tensioning retractors are
located in each seat belt buckle and become
operationally ready with the key in starter switch
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 impact 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 see
page 71.Note:
The emergency tensioning retractors for the driver and
front passenger seats will only deploy if the front seat
belts are buckled.
The rear center automatic two point seat belt is not
equipped with an emergency tensioning retractor.

Te ch n i c a l

cluster displayPractical hints Car care Index Important!
The operational readiness of the airbag system is
verified by the indicator lamp “SRS” in the instrument
cluster when turning the key in starter switch to
position 1 or 2. If no fault is detected, the lamp will go
out after approximately 5 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 5 seconds or if it comes on thereafter,
a malfunction in the system has been detected.
The following system components are monitored or
undergo a self-check: crash-sensor(s), airbag ignition
circuits, front seat belt buckle, emergency tensioning
retractors, seat sensor.
Initially, when the key is turned from starter switch
position 0 to positions 1 or 2, malfunctions in the
crash-sensor are detected and indicated (the “SRS”
indicator lamp stays on longer than 5 seconds or does
not come on).
Have the system checked at your authorized
Mercedes-Benz Light Truck 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.
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 Light Truck Center immediately to
have the system checked; otherwise the “SRS” may
n ot be a ct ivated when need ed in an ac c i den t, whi ch
could result in serious or fatal injury, or it might
deploy unexpectedly and unnecessarily which
could also result in injury.

Front airbags
The driver and front passenger front airbags are
designed to activate only in certain frontal impacts
exceeding a preset threshold.
The front passenger airbag deploys only if the front
passenger seat is occupied and the ü indicator lamp
in the instrument cluster is not illuminated, see
page 271.
Note:
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 in a crash exceeding the appropriate threshold.Important!
Airbags are designed to activate only in certain
frontal (front airbags) impacts which exceed preset
thresholds.
Only during these types of impacts, if of sufficient
severity to meet the deployment thresholds, will
they provide their supplemental protection.
The driver and passenger should always wear their
seat belts, otherwise it is not possible for the airbags
to provide their intended supplemental protection.
In cases of other frontal impacts, angled impacts,
roll-overs, other side impacts, rear collisions, or
other accidents in which the airbags are not
designed to deploy, the airbags will not be activated.
The driver and passenger will then be protected by
the fastened seat belts.
We caution you not to rely on the presence of the
airbags in order to avoid wearing your seat belt.
