With the electronic key in starter switch position 2, a
warning sounds for a short time if the driver’s seat belt
is not fastened.
Automatic comfort-fit seat belt:
An automatic comfort-fit feature for all seat belt is
activated when the electronic key in the starter switch is
turned to position 1 or 2.
The retraction force of the inertia reel is reduced,
increasing the level of seat belt comfort.
Note:
For cleaning and care of the seat belts see page 381.
Wa r n i n g !
Never ride in a moving vehicle with the backrest
reclined. Sitting in an excessively reclined position
can be dangerous. You could slide under the seat
belt in a collision. If you slide under it, the belt
would apply force at the abdomen or neck. That
could cause serious or even fatal injuries. The
backrest and seat belt provide the best restraint
when the wearer is in an upright position and the
belt is properly positioned on the body.

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, side
impact airbags, head protection window
curtain airbags for side windows), “ETR” (seat
belt emergency tensioning retractors), and
front knee bolsters. The system is designed to
enhance the protection offered to properly
belted occupants in certain frontal (front
airbags) and side (side impact and window
curtain airbags) impacts which exceed preset
deployment thresholds.
• Never wear the shoulder belt under your arm,
against your neck or off your shoulder. In a
crash, your body would move too far forward.
That would increase the chance of head and
neck injuries. The belt would also apply too
much force to the ribs or abdomen, which
could severely injure internal organs such as
your liver or spleen.• Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys etc., as these might
cause injuries.• Position the lap belt as low as possible on your
hips and not across the abdomen. If the belt is
positioned across your abdomen, it could cause
serious injuries in a crash.• Each seat belt should never be used for more
than one person at a time. Do not fasten a seat
belt around a person and another person or
other objects.• Belts should not be worn twisted. In a crash,
you wouldn’t have the full width of the belt to
manage impact forces. The twisted belt against
your body could cause injuries.

Special BabySmart
TM compatible child seats, designed
for use with the Mercedes-Benz system and available at
any authorized Mercedes-Benz Center are required for
use with the BabySmart
TM airbag deactivation system.
With the special child seat properly installed, the
passenger front airbag will not deploy.
The 7 indicator lamp located on the center console
will be illuminated, except with electronic key removed
or in starter switch position 0. The system does not
deactivate the door mounted side impact airbag.

After turning electronic key in starter switch to
position 1 or 2, the 7 indicator lamp located on the
center console comes on for approximately 6 seconds
and then extinguishes.
If the indicator lamp should not come on or is
continuously lit, the system is not functioning. You must
see an authorized Mercedes-Benz Center before seating
any child on the front passenger seat. See page 302 for
notes on the 7 indicator lamp.

Wa r n i n g !
The BabySmart
TM airbag deactivation system will
ONLY work with a special child seat designed to
operate with it. It will not work with child seats
which are not BabySmart
TM compatible.
Never place anything between seat cushion and
child seat (e.g. pillow), since it reduces the
effectiveness of the deactivation system.Follow the manufacturer’s instructions for
installation of special child seats.The passenger front airbag will not deploy only if
the 7 indicator lamp remains illuminated.Please be sure to check the indicator every time
you use the special system child seat. Should the
light go out while the restraint is installed, please
check installation. If the light remains out, do not
use the BabySmart
TM restraint to transport children
on the front passenger seat until the system has
been repaired.

cluster displayPractical hints Car care Index Emergency tensioning retractor (ETR)
The seat belts for the front and rear outer 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 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.

Airbags
Front airbags1Driver airbag
2Front passenger airbag
The 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.
Side impact and head protection window curtain airbags
can provide increased protection to belted 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 starter switch
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

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 self-check: crash-sensor(s), airbag ignition
circuits, front seat belt buckles, emergency tensioning
retractors, seat sensor.
Initially, when the electronic key is turned from starter
switch position 0 to position 1 or 2, malfunctions in the
crash sensor 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 299 for information on the Supplemental
Restraint System (SRS) indicator lamp.
The driver and 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
7 indicator lamp on the center console is not
illuminated.
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.
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.
