Important safety notes
GWARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an
accident or trigger unexpectedly, for example.
This poses an increased risk of injury or even fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify an air bag system to
accommodate a person with disabilities, con-
tact an authorized Mercedes-Benz Center for
details. USA only: for further information con-
tact our Customer Assistance Center at
1-800-FOR-MERCedes (1‑800‑367 ‑6372).
Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and
at regular intervals while the engine is run-
ning. Therefore, malfunctions can be detec-
ted in good time.
The 6 restraint system warning lamp in
the instrument cluster lights up when the igni-
tion is switched on. It goes out no later than a
few seconds after the vehicle is started. The
components of the restraint system are in
operational readiness.
A malfunction has occurred if the 6
restraint system warning lamp:
Rdoes not light up after the ignition is
switched on
Rdoes not go out after a few seconds with
the engine running
Rlights up again while the engine is running
GWARNING
If restraint system is malfunctioning, restraint
system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer- gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
PASSENGER AIR BAG OFF indicator
lamp
PASSENGER AIR BAG OFF indicator lamp :
is part of the Occupant Classification System
(OCS).
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the front-
passenger front air bag.
If the PASSENGER AIR BAG OFF indicator
lamp:
Ris lit: the front-passenger front air bag is
deactivated. It will then not be deployed in
the event of an accident.
Rdoes not light up: the front-passenger
front air bag is enabled. If, in the event of an
accident, all deployment criteria are met,
the front-passenger front air bag is
deployed.

The shoulder section of the seat belt must
always be routed across the center of the
shoulder. Adjust the belt outlet if necessary.
XTo raise:slide the belt outlet upwards.
The belt outlet will engage in various posi-
tions.
XTo lower: hold belt outlet release :and
slide belt outlet downwards.
XLet go of belt outlet release :in the
desired position and make sure that the

All seat belts except the driver's seat belt are
equipped with a special seat belt retractor to
securely fasten child restraint systems in the
vehicle. Further information can be found
under "Special seat belt retractor"
(
Ypage 61).
Releasing seat belts
!Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfill their
protective function and must be replaced.
Visit a qualified specialist workshop.

XPress release button :, hold belt
tongue ;firmly and guide it back towards

Seat belt adjustment
The seat-belt adjustment is an integral part of
the PRE-SAFE®convenience function. This
function adjusts the driver's and front-
passenger seat belt to the upper body of the
occupants.
The belt strap is tightened slightly when:
Rthe belt tongue is engaged in the buckle
and
Rthe ignition is switched on
The seat-belt adjustment will apply a certain
retraction force if any slack is detected
between the vehicle occupant and the seat
belt. Do not hold on to the seat belt tightly
while it is adjusting.
You can switch the seat-belt adjustment on
and off in the on-board computer
(
Ypage 286).
Belt warning for the driver and front
passenger

ment cluster is a reminder that all vehicle
occupants must wear their seat belts. It may

light up continuously or flash. In addition,
there may be a warning tone.
Regardless of whether the driver's seat belt
has already been fastened, the7seat belt
warning lamp lights up for six seconds each
time the engine is started. If, after
six seconds, the driver or front-passenger
seat belt has not been fastened and the doors
are closed, the 7seat belt warning lamp
lights up. As soon as the driver's and front-
passenger seat belts are fastened or a front
door is opened again, the 7seat belt
warning lamp goes out.
If the driver's seat belt is not fastened after
the engine is started, an additional warning
tone will sound. This warning tone stops after
six seconds or when the driver's seat belt is
fastened.
If the vehicle's speed exceeds 15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a
warning tone sounds. A warning tone also
sounds with increasing intensity for
60 seconds or until the driver or front
passenger have fastened their seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt
warning is activated again.
iFor more information on the 7seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belts" (
Ypage 325).
Air bags
Introduction
The installation point of an air bag can be rec- ognized by the AIR BAG symbol.
An air bag complements the correctly fas-
tened seat belt. It is no substitute for the seat
belt. The air bag provides additional protec-
tion in applicable accident situations.
Not all air bags are deployed in an accident.
The different air bag systems function inde-
pendently from one another (
Ypage 58). However, no system available today can com-
pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injury
caused by an air bag due to the high speed at
which the air bag must be deployed.
Important safety notes
GWARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sitting correctly and maintain the great-
est possible distance to the air bags
Rfollow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
RAdjust the seats properly before beginning
your journey. Always make sure that the
seat is in an almost upright position. The
center of the head restraint must support
the head at about eye level.
RMove the driver's and front-passenger
seats as far back as possible. The driver's
seat position must allow the vehicle to be
driven safely.
ROnly hold the steering wheel on the out-
side. This allows the air bag to be fully
deployed.
RAlways lean against the backrest while driv-
ing. Do not lean forwards or lean against
the door or side window. You may other-
wise be in the deployment area of the air
bags.
RAlways keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard, for example. Your feet may oth-

PASSENGER AIR BAG OFF indicator lamp:
shows you whether the front-passenger front
air bag is deactivated.
XTurn the SmartKey to position 1or 2in the
ignition lock or on vehicles with KEYLESS-
GO, press the Start/Stop button once or
twice.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds.
The PASSENGER AIR BAG OFF indicator lamp
then displays the status of the front-
passenger front air bag. If the status of the
front-passenger front air bag changes while
the vehicle is in motion, an air bag display
message may appear in the instrument clus-
ter (
Ypage 301). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger
front air bag both before and during the jour-
ney.
If the PASSENGER AIR BAG OFF indicator
lamp:
Ris lit: the front-passenger front air bag is
deactivated. It will then not be deployed in
the event of an accident.
Rdoes not light up: the front-passenger
front air bag is enabled. If, in the event of an
accident, all deployment criteria are met,
the front-passenger front air bag is
deployed.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is
disabled. It will not be deployed in the event of
an accident and cannot perform its intended
protective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
Rthe classification of the person in the front- passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bled in accordance with the person in the
front-passenger seat
Rthe front-passenger seat has been moved
back as far back as possible.
Rthe person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct.
GWARNING
If you secure a child in a child restraint system on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front air bag can
deploy in the event of an accident. The child
could be struck by the air bag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been disabled. The PASSENGER AIR
BAG OFF indicator lamp must be lit.
