61 Safety and Security
Occupant safety
Warning!G
Modifications to or work improperly con-
ducted on restraint systems (such as seat
belts and anchors, emergency tensioning
devices, seat belt force limiters or air bags)
or their wiring, as well as tampering with
interconnected electronic systems, can lead
to the restraint systems no longer function-
ing as intended.
Air bags or emergency tensioning devices,
for example, could deploy inadvertently or
fail to deploy in accidents although the
deceleration threshold for air bag deploy-
ment is exceeded. Therefore, never modify
the restraint systems. Do not tamper with
electronic components or their software.
Warning!G
In the event that the 1 indicator lamp
comes on during driving or does not come
on at all, the SRS self-check has detected a
malfunction. For your safety, we strongly
recommend that you contact an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not deploy when needed in an accident,
which could result in serious personal or
fatal injury, or it might deploy unexpectedly
and unnecessarily which could also result in
injury.
In addition, improper repair work on the SRS
creates a risk of rendering the SRS inopera-
tive or causing unintended air bag deploy-
ment. Work on the SRS must therefore only
be performed by qualified technicians. Con-
tact an authorized Mercedes-Benz Center.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.

62 Safety and Security
Occupant safety
Air bags
Warning!G
Air bags are designed to reduce the poten-
tial of injury and fatality in certain frontal
impacts (front air bags, knee air bags) or
side impacts (head-thorax air bags).
However, no system available today can
totally eliminate injuries and fatalities.
The deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust, however, is neither injurious
to your health, nor does it indicate a fire in
the vehicle. The dust might cause some tem-
porary breathing difficulty for people with
asthma or other breathing trouble. To avoid
this, you may wish to get out of the vehicle
as soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the air bag inflates, then get
fresh air by opening a window or door.
Warning!G
To reduce the risk of injury when the front
air bags inflate, it is very important for the
driver and passenger to always be in a prop-
erly seated position and to wear their seat
belts.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the backrest. Fasten
your seat belt and make sure that it is prop-
erly positioned on your body (
page 45).
Since the air bag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it inflates
with great force in the blink of an eye:

Sit properly belted in a nearly upright
position with your back against the seat
backrest.

Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper op-
eration of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the air bag cover
on the steering wheel must be at least
10 inches (25 cm) or more. You should
be able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see an authorized
Mercedes-Benz Center.

Do not lean your head or chest close to
the steering wheel or dashboard.

Keep hands on the outside of steering
wheel rim. Placing hands and arms
inside the rim can increase the risk and
potential severity of hand/arm injury
when driver’s front air bag inflates.

63 Safety and Security
Occupant safety

Adjust the passenger seat as far as pos-
sible rearward from the dashboard when
the seat is occupied.

Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
head-thorax air bag inflates. This could
result in serious injuries or death should
the air bag be deployed. Always sit as
upright as possible, properly use the
seat belts and an appropriately sized in-
fant, or toddler restraint, or booster seat
recommended for the size and weight of
the child.
Failure to follow these instructions can
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual.
Warning!G
There is a possibility of a head-thorax air bag
related injury if occupants, especially chil-
dren, are not properly seated or restrained
when next to a head-thorax air bag which
needs to deploy rapidly in a side impact in
order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
head-thorax air bag inflates. This could
result in serious injuries or death should
the head-thorax air bag be deployed.
(2) Always sit as upright as possible, prop-
erly use the seat belts, and for children
12 years old or under, use an appropri-
ately sized infant, or toddler restraint, or
booster seat recommended for the size
and weight of the child.
(3) Always wear seat belts properly.
If you believe that, even with the use of
these guidelines, it would be safer for your
passenger seat occupants to have the pas-
senger head-thorax air bag deactivated,
then deactivation can be accomplished
upon your written request to do so at an
authorized Mercedes-Benz Center at an
additional cost.
Please contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center (in the USA) at
1-800-FOR-MERCedes (1-800-367-6372) or
Customer Service (in Canada) at
1-800-387-0100 for details.

64 Safety and Security
Occupant safety
Safety guidelines for the seat belt,
emergency tensioning device and air
bagiAir bags are designed to activate only in cer-
tain frontal impacts (front air bags, knee air
bags) and side impacts (head-thorax air bags)
which exceed preset thresholds. Only during
these types of impacts will they provide their
supplemental protection.
The driver and passenger should always wear
their seat belts. Otherwise it is not possible for
the air bags to provide their supplemental
protection.
In cases of other types of impacts and impacts
below air bag deployment thresholds, air bags
will not deploy. The driver and passenger will
then be protected to the extent possible by a
properly fastened seat belt. A properly fastened
seat belt is also needed to provide the best pos-
sible protection in a rollover.
We caution you not to rely on the presence of the
air bags in order to avoid wearing your seat belt.
It is important to your safety and that of your pas-
senger that you replace deployed air bags and
repair any malfunctioning air bags to ensure that
the vehicle will continue to provide supplemental
crash protection for occupants.
Warning!G

Damaged seat belts or seat belts that
were highly stressed in an accident
must be replaced and their anchoring
points must also be checked. Only use
seat belts installed or supplied by an
authorized Mercedes-Benz Center.

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

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

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

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.

No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or
removing 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, outboard sides of the front seat
backrests, door trim panels, or door trim
panels, and installation of additional
electrical/electronic equipment on or
near SRS components and wiring. Keep
area between air bags and occupants
free from objects (e.g. packages,
purses, umbrellas, etc.).

Air bag system components will be hot
after an air bag 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.

Occupant safety
Occupant Classification System
The O
ccupant Classification System (OCS)
automatically turns the passenger front air
bag and passenger-side knee air bag on or
off based on the classified occupant
weight category determined by weight
sensor readings from the passenger seat.
Occupants must sit properly belted in a
position that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by
leaning on armrests), the OCS may not be
able to properly approximate the
occupant’s weight category. Both driver and the passenger should
always use the PASSENGER AIR BAG OFF
indicator lamp (
page 70) as an indica-
tion of whether or not the passenger is
properly positioned.
iThe system does not deactivate the
head-thorax air bag and the emergency tension-
ing device.
iIf the seat needs to be serviced in any way,
take the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used. Warning!G
If the PASSENGER AIR BAG OFF indicator
lamp illuminates when an adult or someone
larger than a small individual is in the pas-
senger seat, have the passenger re-position
himself or herself in the seat until the
PASSENGER AIR BAG OFF indicator lamp
goes out.
For information on air bag display
messages, see (
page 319).
In the event of a collision, the air bag control
unit will not allow passenger front air bag or
passenger knee air bag deployment when
the OCS classified the passenger seat occu-
pant as being up to or less than the weight
of a typical 12-month-old child in a standard
child restraint or if the passenger seat is
sensed as being empty.


69 Safety and Security
Occupant safety
Warning!G
Children 12 years old and under must be
seated and properly secured in an appropri-
ate infant or child restraint recommended
for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt fully in
accordance with the child seat manufactur-
er’s instructions.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information:

Your vehicle is equipped with air bag
technology designed to turn off the pas-
senger front air bag and the passenger
knee air bag in your vehicle when the
system senses the weight of a typical
12-month-old child or less along with
the weight of a standard appropriate
child restraint on the passenger seat.

A child in a rear-facing child restraint on
the passenger seat will be seriously
injured or even killed if the passenger
front air bag and/or the passenger knee
air bag inflate in a collision which could
occur under some circumstances, even
with the air bag technology installed in
your vehicle.

If you install a rear-facing child restraint
on the passenger seat, make sure that
the PASSENGER AIR BAG OFF indicator
lamp is illuminated, indicating that the
passenger front air bag and the passen-
ger knee air bag are deactivated. Should
the PASSENGER AIR BAG OFF indicator
lamp not illuminate or go out while the
restraint is installed, please check in-
stallation. Periodically check the
PASSENGER AIR BAG OFF indicator
lamp while driving to make sure the
PASSENGER AIR BAG OFF indicator
lamp is illuminated. If the PASSENGER
AIR BAG OFF indicator lamp goes out or
remains out, do not transport a child on
the passenger seat until the system has
been repaired. A child in a rear-facing
child restraint on the passenger seat will
be seriously injured or even killed if the
passenger front air bag and/or the
passenger knee air bag inflate.

If you place a child in a forward-facing
child restraint on the passenger seat,
move the seat as far back as possible,
use the proper child restraint recom-
mended for the age, size and weight of
the child, and secure child restraint with
the vehicle’s seat belt according to the
child seat manufacturer’s instructions.
For children larger than the typical
12-month-old child, the passenger front
air bag and the passenger knee air bag
may or may not be activated
(
page 68).

70 Safety and Security
Occupant safety
The PASSENGER AIR BAG OFF indicator
lamp is located in lower part of the center
console.
1Passenger front air bag off indicator
lamp
The PASSENGER AIR BAG OFF indicator
lamp1 will be illuminated, except with
the SmartKey removed or in starter switch
position0.iDeployment of the driver front air bag does
not mean that the passenger front air bag also
should have deployed.
The Occupant Classification System (
page 67)
may have determined:

that the seat was empty or occupied by the
weight up to or less than that of a typical
12-month-old child seated in a standard
child restraint – both instances where the
system suppresses deployment of the
passenger front air bag even though the
impact met the criteria and was of sufficient
severity to deploy the driver front air bag

that the seat was occupied by a small individ-
ual (such as a young teenager or a small
adult) or a child weighing more than the
weight of a typical 12-month-old child in a
standard child restraint – instances where
the system may suppress deployment of the
passenger front air bag even though the
impact met the criteria and was of sufficient
severity to deploy the driver front air bag
Warning!G
If the 1indicator lamp and the
PASSENGER AIR BAG OFF indicator lamp
are lit at the same time, there is a malfunc-
tion in the Occupant Classification System.
The passenger front air bag and the passen-
ger knee air bag will be deactivated in this
case.
In order to ensure proper operation of the
air bag system and OCS:

Have the system checked as soon as
possible by qualified technicians.
Contact an authorized Mercedes-Benz
Center.

Sit properly belted in a nearly upright
position with your back against the seat
backrest.

Do not lean on the armrests or lift your-
self from the seat by using the handle
over the door as this may cause the OCS
to be unable to correctly approximate
the occupant weight category.

71 Safety and Security
Occupant safety
Self-test Occupant Classification
System
After turning the SmartKey in the starter
switch to position1 or2, the PASSENGER
AIR BAG OFF indicator lamp located in the
center console illuminates. If an adult oc-
cupant is properly sitting on the passenger
seat and the system senses the occupant
as being an adult, the PASSENGER AIR
BAG OFF indicator lamp will illuminate and
go out after approximately 6 seconds.
If the seat is not occupied and the system
senses the passenger seat as being empty,
the PASSENGER AIR BAG OFF indicator
lamp will illuminate and not go out. For more information, see the “Practical
hints” section (
page 312).
Seat belts
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 when ever the vehicle is in motion.
For information on fastening seat belts,
see “Fastening the seat belts” (
page 45).

Only have the seat repaired or replaced
by an authorized Mercedes-Benz
Center.

Read and observe all warnings in this
chapter.
Warning!G
If the PASSENGER AIR BAG OFF indicator
lamp should not illuminate, the system is
not functioning. You must contact an autho-
rized Mercedes-Benz Center before seating
any child on the passenger seat.
Warning!G
Never place anything between seat
cushion and child seat (e.g. pillow), since it
reduces the effectiveness of the Occupant
Classification System. The bottom of the
child seat must make full contact with the
passenger seat cushion. An incorrectly
mounted child seat could cause injuries to
the child in case of an accident, instead of
increasing protection for the child.
Follow the manufacturer’s instructions for
installation of child seats.

eling with you in the vehicle and restraint sys-
tems for infants and children, see “Children in
the vehicle” (
