Mercedes-Benz - Air Bag Restraint Systems
DESCRIPTION & OPERATION
All models are equipped with Supplemental Restraint System (SRS). The main components of SRS are driver-
side air bag module, passenger-side air bag module, side impact air bag modules (located in doors), SRS control
module, side air bag sensors, SRS warning light, driver-side knee bolster, passenger-side knee bolster and seat
belt pretensioners or Emergency Tensioning Retractor (ETR) seat belt assembly. Additionally, some vehicles
may be equipped with head impact (curtain type) air bags.
Both SRS and ETR are electronically activated by a single control module. There are 2 thresholds which must
be exceeded to trigger an ETR action, air bag deployment, or both. If a moderately severe frontal collision
occurs exceeding first triggering threshold where protection from seat belt is sufficient, only Emergency
Tensioning Retractor (ETR) is activated if seat belt is buckled. If a moderately severe frontal collision occurs
exceeding first triggering threshold where protection from seat belt is sufficient, but seat belt is not buckled, air
bag is deployed and ETR is not activated.
If a severe frontal collision occurs exceeding second triggering threshold where protection from seat belt is
insufficient, air bag is deployed. ETR is activated if seat belt is buckled. If seat belt is not buckled, ETR is not
activated when second triggering threshold is reached. Passenger air bag will deploy even if passenger seat is
not occupied when a triggering threshold is exceeded. During certain types of collisions, the air bags will be
deploy, but ETRs will not be activated.
The side air bag on the driver-side deploys whenever the driver-side air bag module is deployed and when there
is a substantial side impact crash. The air bag on the passenger-side will activate only when a sensor (Occupied
Seat Recognition Sensor) in the passenger seat sends a signal to the SRS control module that the passenger-side
seat is occupied. Side air bags mounted in rear doors will deploy when side impacts occur that exceed preset
parameters.
Head impact air bag modules will deploy when certain side impacts occur that exceed preset parameters. Head
impact air bag will deploy independently of other air bags on side of impact.

61 Safety and Security
Occupant safety
To help avoid the possibility of injury, please
follow these guidelines: (1) occupants, espe-
cially children, should never place their bod-
ies or lean their heads in the area of the door
where the side airbag inflates. This could re-
sult in serious injuries or death should the
side airbag be activated; (2) always sit up-
right, properly use the seat belts and use an
appropriately sized infant or child restraint
system for all children 12 years old or under;
and (3) always wear seat belts properly.
If you believe that, even with the use of
these guidelines, it would be safer for your
rear seat occupants to have both rear door
mounted side airbags deactivated, then de-
activation can be accomplished upon your
written election to do so at your authorized
Mercedes-Benz Light Truck Center at an ad-
ditional cost. Please contact your local au-
thorized Mercedes-Benz Light Truck Center
or call our Customer Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372)
for details.
iAirbags are designed to activate only in
certain frontal (front airbags) impacts,
or side (side impact and head protec-
tion window curtain airbags) impacts
which exceed preset thresholds.
Only during these types of impacts, if of
sufficient severity to meet the deploy-
ment thresholds, will they provide their
supplemental protection.
The driver and passenger should al-
ways wear their seat belts. Otherwise it
is not possible for the airbags to pro-
vide their supplemental protection.
In cases of other frontal impacts, an-
gled impacts, roll-overs, other side im-
pacts, rear collisions, or other
accidents, the airbags will not be acti-
vated. The driver and passengers will
then be protected by the fastened seat
belts.
We caution you not to rely on the pres-
ence of the airbags in order to avoid
wearing your seat belt.
Your vehicle was originally equipped
with airbags that are designed to acti-
vate in certain impacts exceeding a
preset threshold to reduce the poten-
tial and severity of injury. It is important
to your safety and that of your passen-
ger that you replace deployed airbags
and repair any malfunctioning airbags
to ensure that the vehicle will continue
to provide supplemental crash protec-
tion for occupants.

Front airbags
1Driver airbag
2Passenger front airbag
3Side impact airbag
Driver and passenger front airbags are
deployed:
in the event of a frontal impact
if impact exceeds a preset deployment
threshold
independently of the side impact air-
bagsThe airbags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protec-
ted by the fastened seat belts.
The passenger front airbag will only be
deployed if:
the passenger seat is occupied
the 7indicator lamp in the instru-
ment cluster is not lit (
page 26)
the impact exceeds a preset deploy-
ment threshold
Warning!
G
In the event that the 1malfunction indi-
cator lamp comes on while driving, the SRS
may not be operational. For your safety, we
strongly recommend that you visit an autho-
rized Mercedes-Benz Light Truck Center im-
mediately to have the system checked;
otherwise the SRS may not be activated
when needed in an accident, which could re-
sult in serious or fatal injury, or it might de-
ploy unexpectedly and unnecessarily which
could also result in injury.
!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front or side
impact airbag on the front passenger
side to deploy in a crash which exceeds
the system's deployment threshold.

3Side impact airbag, front
The side impact airbags and window
curtain airbags are deployed:
on the impacted side of the vehicle
in impacts exceeding a preset deploy-
ment threshold
independently of the front airbagsThe front passenger side impact airbag will
only deploy if the system senses that the
front passenger seat is occupied.
The side impact airbags and window
curtain airbags are not deployed in im-
pacts which do not exceed the system’s
deployment threshold.
Seat belts
When the engine is started, the seat belt
non-usage warning lamp< illuminates
to remind you and your passengers to
fasten your seat belts. If the driver’s seat
belt is not fastened before the engine is
started, the seat belt non-usage warning
lamp< illuminates and a warning
chime sounds for approximately
six seconds when the engine is started.The use of seat belts and infant and child
restraint systems is required by law in all
50 states and all Canadian provinces. Even
where this is not the case, all vehicle occu-
pants should have their seat belts fastened
whenever the vehicle is in motion.
Information on fastening seat belts is
found in the “Getting started” section
(
page 42).iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 67).

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 airbag,
front passenger airbag, front and rear
door mounted side impact airbags and
window curtain airbags), ETD (seat belt
emergency tensioning device for the
outboard passenger seats [except in the
optional third row seats]), and front seat
knee bolsters.
The system is designed to enhance the pro-
tection offered to properly belted occupants
in certain frontal (front airbags) and side
(side impact airbags and window curtain air-
bags) impacts which exceed preset deploy-
ment thresholds.
Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. 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 se-
verely 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 abdo-
men. If the belt is positioned across your
abdomen, it could cause serious injuries
in a crash.
Never use a seat belt for more than one
person at 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.
Pregnant women should also use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.
Never place your feet on the instrument
panel or on the seat. Always keep both
feet on the floor in front of the seat.

Occupant safety
Emergency tensioning device, seat belt
force limiter
The seat belts for the front seats are
equipped with emergency tensioning de-
vices and belt force limiters. The outboard
passenger seats belts (except in the third
row seats*) are equipped with emergency
tensioning devices.
The ETD is designed to activate only when
the seat belt is fastened and in the follow-
ing cases:
in frontal or rear-end impacts exceed-
ing a preset severity level
if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 58)
In an impact, emergency tensioning devic-
es remove slack from the belts in such a
way that the seat belts fit more snugly
against the body. Belt force limiters reduce
the force exerted by the seat belts on oc-
cupants during a crash.
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 and recommended for
use by Mercedes-Benz.
Ensure that the infant or child is prop-
erly secured by a belt at all times while
the vehicle is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
Mercedes-Benz Light Truck Center.
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 Light Truck Center.!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front or side
impact airbag on the front passenger
side to deploy in a crash which exceeds
the system’s deployment threshold.
