iAirbags are designed to activate only in
certain frontal impacts (front airbags,
driver-side knee bag) and side impacts
(head-thorax airbags) which exceed
preset thresholds. Only during these
types of impacts, if of sufficient severi-
ty to meet the deployment threshold,
will they provide their supplemental
protection.
The driver and passengers should al-
ways wear their seat belts. Otherwise it
is not possible for the airbags to pro-
vide their intended supplemental pro-
tection.
In cases of other frontal impacts, an-
gled impacts, roll-overs, other side im-
pacts, rear collisions, or other
accidents and impacts below airbag
deployment thresholds, the airbags will
not be activated. The driver and pas-
senger will then be protected to the ex-
tent possible by a properly fastened
seat belt.
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 which are designed to ac-
tivate 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.

Safety guidelines for the seat belt,
emergency tensioning device and
airbag
When you sell your vehicle, we strongly
urge you to give notice to the subsequent
owner that it is equipped with an SRS by
alerting them to the applicable section in
the Operator’s Manual.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 belts in-
stalled or supplied by an authorized
Mercedes-Benz Center.
Airbags and ETDs (Emergency Tension-
ing Devices) are designed to function on
a one-time-only basis. An airbag 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 airbag cov-
er, outboard sides of the front seat
backrests, 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 airbags 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.
Airbag system components will be hot
after an airbag has inflated. Do not
touch.
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.
In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air-
bag deployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact an authorized
Mercedes-Benz Center.
For your protection and the protection
of others, when scrapping the airbag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from your authorized Mercedes-Benz
Center.
Given the considerable deployment
speed and the textile structure of the
airbags, there is the possibility of abra-
sions or other injuries resulting from air-
bag deployment.
70 Safety and SecurityOccupant safetyFront airbags
Driver and passenger airbags are de-
ployed:
in the event of certain frontal impacts
if impact exceeds a preset deployment
threshold
independently of the head-thorax air-
bags
The airbags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.
The passenger airbag will only be deployed
if:
the passenger seat is occupied
the 7 indicator lamp on the glove
box is not lit (
page 78)
the impact exceeds a preset deploy-
ment threshold1Driver airbag
2Passenger airbag
3Knee bagKnee bag
The knee bag is located on the driver-side
lower instrument panel. It is designed to
operate together with the driver airbag in
certain frontal impacts exceeding a preset
threshold. The knee bag operates best in
conjunction with a properly positioned and
fastened seat belt.
!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front airbag
or the head-thorax airbag on the front
passenger side to deploy in a crash
which exceeds the system’s deploy-
ment threshold.
71 Safety and Security
Occupant safety
Head-thorax airbags
The head-thorax airbags are deployed:
on the impacted side of the vehicle
in impacts exceeding a preset deploy-
ment threshold
independently of the front airbags
The head-thorax airbags are not deployed
in impacts which do not exceed the sys-
tem’s deployment threshold.
The passenger head-thorax airbag will only
deploy if the system senses that the pas-
senger seat is occupied.

Seat belts
When the engine is started, the seat belt
telltale< illuminates for a maximum of
6 seconds and a warning chime sounds to
remind you and your passenger to fasten
your seat belts.
If after these 6 seconds, the driver’s or the
passenger’s seat belt (with the passenger
seat occupied) are not fastened with all
doors closed,
and the vehicle speed does not exceed
15 mph (25 km/h), the seat belt
telltale< remains illuminated for as
long as either the driver’s or
passenger’s seat belt is 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
passenger’s seat belt are fastened, or
for a maximum of 60 seconds from
the time the vehicle speed exceeded 15 mph (25 km/h) if either
the driver’s or passenger’s seat belt
remains unfastened.
If the driver’s or passenger’s seat belt
remains unfastened after 60 seconds,
the seat belt telltale< stops flash-
ing and the warning chime stops
sounding. The seat belt telltale<
then continues to be illuminated for as
long as either the driver’s or passen-
ger’s seat belt are not fastened.
The seat belt telltale< will only go out
if both the driver’s and the passenger’s
seat belt (with the front passenger seat oc-
cupied) are fastened, or the vehicle is
standing still and a front door is opened.
For more information, see the “Practical
hints” section (
page 340).
72 Safety and SecurityOccupant safetyAlways wear your seat belt. All vehicle
occupants always need to have their seat
belts fastened and wear them properly.
In addition, applicable motor vehicle safety
laws require you to wear seat belts. Even
where this is not the case, we strongly rec-
ommend that all vehicle occupants have
their seat belts fastened and wear them
properly.
For information on fastening seat belts,
see “Fastening the seat belts” (
page 46).

traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 76).
Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passenger should al-
ways wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are properly wearing
your seat belt. Airbags can only protect as
they are designed if the occupants are prop-
erly wearing their seat belts (
page 65).
Warning!
G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this 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 ab-
domen or neck. This could cause serious or
even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a nearly upright position and the
belt is properly positioned on the body.
Keep door storage compartments closed
while vehicle is in motion. Failure to do so
may cause the seat belt to catch at the rear
and prevent proper positioning of the seat
belt.

Warning!
G
Never let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly re-
strained with a separate seat belt. Never use
a seat belt for more than one person at a
time.
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.

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, driv-
er-side knee bag, passenger airbag,
head-thorax airbags) and ETD (seat belt
emergency tensioning device). The sys-
tem is designed to enhance the protec-
tion offered to properly belted
occupants in certain frontal (front air-
bags, driver-side knee bag and ETD) and
side (head-thorax airbags and ETD) im-
pacts which exceed preset deployment
thresholds.

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.!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 passenger side
and, with the seat belt fastened to
secure the object, the ETD to deploy in
a crash which exceeds the system's
deployment threshold.
Warning!
G
This vehicle is a two occupant vehicle. The
rear storage area is not intended for use by
occupants and is not equipped for properly
seating or restraining occupants. Thus this
area should never be used by any persons.
Before operating the roll bar switch make
sure that the roll bar’s path is clear and no
persons are injured by the moving roll bar
due to inattention. Raising or lowering of the
roll bar could injure someone inadvertently
occupying the rear storage area.
For your own safety, we recommend to drive
with the roll bar raised if the outside temper-
ature is below +5°F (-15°C).!If the outside temperature falls below
+5°F (-15°C), the roll bar must be
raised manually using the buttons pro-
vided to avoid damaging the hydraulics.
iWhen the roll bar is raised automatical-
ly, you will hear a ratcheting sound.

Infant and child restraint systems
Only use a BabySmart
TM compatible child
restraint for the front passenger seat in
this vehicle.
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
The passenger lap-shoulder belt has a spe-
cial seat belt retractor for the secure fas-
tening of child restraints.
To fasten a child restraint follow child re-
straint instructions for mounting. Then pull
the shoulder belt out completely and let it
retract. During the 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.The use of infant or child restraints is re-
quired by law in all 50 states, the District of
Columbia, the U.S. territories, and all Ca-
nadian provinces.
Infants and small children should be seat-
ed in an appropriate infant or child re-
straint system which is properly secured
by a lap-shoulder belt and that complies
with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle
Safety Standard 213.
A statement by the child restraint manu-
facturer of compliance with this standard
can be found on the instruction label on
the restraint and in the instruction manual
provided with the restraint.When using any infant or child restraint
system, be sure to carefully read and fol-
low all manufacturer’s instructions for in-
stallation and use.
Please read and observe warning labels af-
fixed to inside of vehicle and to infant or
child restraints.
Warning!
G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.
Warning!
G
Children 12 years old and under must never
ride in this vehicle, except in a
Mercedes-Benz authorized BabySmart
TM
compatible child seat, which operates with
the BabySmart
TM system installed in the ve-
hicle to deactivate the passenger front air-
bag when it is properly installed. Otherwise
they will be struck by the airbag when it in-
flates in a crash. If this happens, serious or
fatal injury will result.
