67 Safety and Security
Occupant safety
Warning!G
Accident research shows that the safest
place for children in an automobile is in the
rear seat.
There is a possibility for a side impact air
bag related injury if occupants, especially
children, are not properly seated or re-
strained when next to a front side impact air
bag and/or rear side impact 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 or the rear
side trim panel where the front side im-
pact air bag and/or the rear side impact
air bag* inflates.
This could result in serious injuries or
death should the front side impact air
bag and/or the rear side impact air bag*
be deployed.
(2) Always sit as upright as possible,
properly use the seat belts, and for
children 12 years old and under, use an
appropriately 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
rear seat occupants to have the rear mount-
ed side impact air bags* deactivated, then
deactivation can be accomplished upon
your written request to do so at an autho-
rized Mercedes-Benz Center at an additional
cost.
Please contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.iAir bags are designed to deploy only in cer-
tain frontal impacts (front air bags) and in side
impacts (front side impact air bags, rear side im-
pact air bags*, and window curtain air bags)
which exceed preset thresholds. Only during
these events 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 pro-
tection.
In case of other types of impacts and impacts be-
low 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 possible pro-
tection 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-
sengers that you replace deployed air bags and
repair any malfunctioning air bags to make sure
that the vehicle will continue to provide supple-
mental crash protection for occupants.

69 Safety and Security
Occupant safety
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.
Front air bags
1Driver air bag
2Passenger air bagDriver and front passenger front air bags
are deployed:

in the event of certain frontal impacts

if impact exceeds a preset deployment
threshold

independently of the front side impact
air bag and/or the rear side impact air
bag*The air bags 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 front passenger front air bag will only
be deployed if:
the system, based on OCS weight sen-
sor readings, senses that the front pas-
senger seat is occupied

the 56 indicator lamp in the
center console is not lit (
page 74).

the impact exceeds a preset deploy-
ment threshold
iThe front air bags in this vehicle have been
designed to inflate in two stages. This allows the
air bag to have different rates of inflation that are
based on the rate of relevant vehicle decelera-
tion as assessed by the air bag control unit.
On the front passenger side, the front air bag de-
ployment is additionally influenced by the pas-
senger’s weight category as identified by the
Occupant Classification System (OCS)
(
page 70).
The lighter the front passenger side occupant,
the higher the vehicle deceleration rate required
for the second stage inflation of the air bag.

2Rear side impact air bag*
3Window curtain air bagThe front side impact air bags, the rear
side impact air bags*, and the window
curtain air bags are deployed:

on the impacted side of the vehicle

in impacts exceeding a preset deploy-
ment threshold

independently of the front air bags
The front side impact air bags, the rear
side impact air bags*, and the window cur-
tain air bags are not deployed in impacts
which do not exceed the system’s deploy-
ment threshold.
Occupant Classification System
The O
ccupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
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.
iThe system does not deactivate the front
passenger side impact air bag, the window cur-
tain air bag and the emergency tensioning
device.

72 Safety and Security
Occupant safety
When the OCS senses that the front passen-
ger seat occupant is classified as an adult or
someone larger than a small individual, the
56 indicator lamp will illuminate for
approximately 6 seconds when the engine is
started and then go out, indicating that the
front passenger front air bag is activated.
If the 56 indicator lamp is
illuminated, the front passenger front air
bag is deactivated and will not be deployed.
If the 56 indicator lamp is not
illuminated, the front passenger front air
bag is activated and will be deployed:

in the event of certain frontal impacts

if impact exceeds a preset deployment
threshold

independently of the front side impact
air bags and/or rear side impact air
bags*.
If the front passenger front air bag is
deployed, the rate of inflation will be
influenced by:

the rate of vehicle deceleration as as-
sessed by the air bag control unit

front passenger’s weight category as
identified by the Occupant Classification
System (OCS).
Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriate infant or child restraint recom-
mended for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors
and top tether strap, fully in accordance
with the child seat manufacturer’s
instructions.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the front
passenger seat:

Your vehicle is equipped with air bag
technology designed to turn off the front
passenger front 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 appropri-
ate child restraint on the front passen-
ger seat.

Enhanced seat belt reminder system
When the engine is started, the seat belt
telltale< will always illuminate
for 6 seconds to remind you and your pas-
sengers to fasten your seat belts.
If the driver’s seat belt is not fastened
when the engine is started, an additional
warning chime will also sound for a maxi-
mum of 6 seconds or until the driver’ s
seat belt is fastened.
If after these 6 seconds the driver’s or the
front passenger’s seat belt (with the front
passenger seat occupied) is not fastened
with both doors closed,

the seat belt telltale< remains illu-
minated for as long as either the driv-
er’s or front passenger’s seat belt is not
fastened.

and if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt
telltale< starts flashing and a
warning chime sounds with increasing
and side (front side impact air bags, rear
side impact air bags*, window curtain
air bags and ETD) impacts which exceed
preset deployment thresholds.

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
increase the chance of head and neck
injuries. 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.

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-
m e n . I f t h e b e l t i s p o s i t i o n e d a c r o s s y o u r
abdomen, it could cause serious injuries
in a crash.

Never use a seat belt for more than one
person at a 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 distribute impact forces.
The twisted belt against your body could
cause injuries.

Pregnant women should also always use
a lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible
pressure on the abdomen.

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.

When using a seat belt to secure infant
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer’s instructions.

Active head restraints
The active front seat head restraints are in-
tended to offer the driver and front passen-
ger increased protection from whiplash
type injuries in rear-end collisions. In the
event of a rear-end collision exceeding the
systems’ deployment threshold, the active
head restraints on the driver’s and front
passenger’s seats are designed to move
forward in the direction of travel, providing
the head with increased support earlier on
in the collision sequence. The active head
restraints activate whether the seat is oc-
cupied or not.You cannot remove the active head re-
straint on the driver’s and front passen-
ger’s seat.
For removal of the active head restraints
we recommend that you contact an
authorized Mercedes-Benz Center.
For information on head restraint adjust-
ment, see “Seats” (
page 39).
For information on resetting the activated
active head restraints, see “Resetting acti-
vated head restraints” (
page 403).
Warning!G
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is as
close to the head as possible and the center
of the head restraint supports the back of
the head at eye level. This will reduce the
potential for injury to the head and neck in
the event of an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an
accident.
Warning!G
Only use seat or head restraint covers which
have been tested and approved by
Mercedes-Benz for your vehicle model.
Using other seat or head restraint covers
may interfere with or prevent the activation
of the active head restraints. Contact an
authorized Mercedes-Benz Center for
availability.
Do not attach any objects (e.g. hangers) to
the head restraint posts. Otherwise, the ac-
tive head restraints may not be able to func-
tion properly or offer the intended degree of
protection in the event of an accident.
