64 Safety and SecurityOccupant safety
Safety guidelines for the seat belt,
emergency tensioning device and
air bag In case of other types of impacts and
impacts below air bag deployment
thresholds, air bags will not be de-
ployed. The driver and passenger will
then be protected to the extent possi-
ble by a properly fastened seat belt. A
properly fastened seat belt is also
needed to provide the best possible
protection in a rollover.
We caution you not to rely on the pres-
ence of the air bags in order to avoid
wearing your seat belt.
It is important to your safety and that of
your passengers that you replace de-
ployed air bags and repair any malfunc-
tioning air bags to make sure that the
vehicle will continue to provide supple-
mental crash protection for occupants.Warning!
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 in-
stalled or supplied by an authorized
Mercedes-Benz Center.


Air bags and emergency tensioning de-
vices (ETDs) are designed to function on
a one-time-only basis. An air bag or ETD
that was activated must be replaced.


No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges etc. over the steering
wheel hub, passenger front air bag cov-
er, door trim panels,
or door frame trims, and installation of
additional electrical/electronic equip-
ment on or near SRS components and
wiring. Keep area between air bags and
occupants free from objects (e.g. pack-
ages, purses, umbrellas, etc.).


Do not pass belts over sharp edges.
They could tear.


Do not make any modification that could
change the effectiveness of the belts.


Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.


Do not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may turn into projec-
tiles and cause head and other injuries
when curtain air bag is deployed.


Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.

67 Safety and Security
Occupant safety
In addition, the window curtain air bags 2
are deployed:

in certain vehicle rollovers
The front passenger side impact
air bags1 will only deploy if the system
senses that the front passenger seat is oc-
cupied.
The side impact air bags and window cur-
tain air bags are not deployed in impacts
which do not exceed the system’s deploy-
ment threshold.
Seat belts
When the engine is started the seat belt
telltale< illuminates for a maximum of
six seconds and a warning chime sounds
to remind you and your passengers to fas-
ten your seat belts.If after these six seconds, the driver's or
the front passenger's seat belt (with the
front passenger seat occupied) are not fas-
tened with all doors closed,


and the vehicle speed does not exceed
15 mph (25 km/h), the seat belt tell-
tale < remains illuminated for as
long as either the driver's or front pas-
senger's seat belt are not fastened.


and the vehicle speed exceeds 15 mph
(25 km/h), the seat belt telltale <
starts flashing and a warning chime
sounds with increasing intensity until
both the driver's and front passenger's
seat belt are fastened, or for a maxi-
mum of 60 seconds from the time the
vehicle speed exceeded 15 mph
(25 km/h) if either the driver's or front
passenger's seat belt remains unfas-
tened.
If the driver's or front passenger's seat
belt remains unfastened after 60 sec-
onds, the seat belt telltale< stops
flashing and the warning chime stops
sounding. The seat belt telltale < then continues to be illuminated for as
long as either the driver's or front pas-
senger's seat belt are not fastened.
The seat belt telltale will only go out if both
the driver and front passenger's seat belt
(with the front passenger seat occupied)
are fastened, or the vehicle is standing still
and a front door is opened.

(
page 362)
The use of seat belts and infant and child
restraint systems is required by law in all
50 states, the District of Columbia, the
U.S. territories and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts fas-
tened whenever the vehicle is in motion.
For more information, see “Fastening the
seat belts” (
page 43).

Warning!
G
Damaged seat belts or belts that were highly
stressed in an accident must be replaced
and their anchoring points must also be
checked.
Only use seat belts which have been ap-
proved by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
or to failure.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Center.
Warning!
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 sec-
tion, as that could result in serious inju-
ries 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, includ-
ing rollovers. The integrated restraint
system includes SRS (driver air bag, pas-
senger front air bag, side impact
air bags, head protection window cur-
tain air bags for side windows), ETD
(seat belt emergency tensioning device),
and front seat knee bolsters.
The system is designed to enhance the
protection offered to properly belted oc-
cupants in certain frontal (front air bags
and ETD) and side (side impact and win-
dow curtain air bags and ETD) impacts
which exceed preset deployment
thresholds and in certain rollovers (win-
dow curtain air bags and ETD).


Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a frontal crash, your body would
move too far forward. That would in-
crease the chance of head and neck in-
juries. The belt would also apply too
much force to the ribs or abdomen,
which could severely injure internal or-
gans such as your liver or spleen.


71 Safety and Security
Occupant safety
In an impact, emergency tensioning devic-
es remove slack from the belts. Belt force
limiters reduce the force exerted by the
seat belts on occupants during a crash.
Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats reduces the retracting force of the
seat belts when they are in normal use.
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:

Secure the child using an infant or child
restraint appropriate to the age and
size of the child.


Make sure that the infant or child is
properly secured at all times while the
vehicle is in motion.
Infant and child restraint seats and
information on choosing an appropriate
restraint system can be obtained from any
Mercedes-Benz Center.Infant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
All lap-shoulder belts except the driver’s
seat belt have special seat belt retractors
for secure fastening of child restraints.
To fasten a child restraint, follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
let it retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The belt is now locked. Push down
on child restraint to take up any slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual man-
ner.
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be
followed. These are available at your autho-
rized Mercedes-Benz Center.
