65 Safety and Security
Occupant safety
serious injuries or death should the side
air bag be activated.
(2) Always sit nearly upright, properly use
the seat belts and use an appropriately
sized infant or child restraint system for
all children 12 years old or under.
(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 air bags deactivated, then deactiva-
tion can be accomplished upon your written
request to do so at your authorized
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 activate only
in certain frontal (front air bags) im-
pacts, side impacts (side impact and
head protection window curtain
air bags) which exceed preset thresh-
olds and in certain rollovers (head pro-
tection window curtain air bags). Only
during these events will they provide
their supplemental protection.
The driver and passengers should al-
ways wear their seat belts. Otherwise it
is not possible for air bags to provide
their supplemental protection.
In case of other types of impacts and
impacts below air bag deployment
thresholds, air bags will not be activat-
ed. The driver and passenger will then
be protected to the extent possible by
a properly fastened seat belt. A proper-
ly 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.
Your vehicle was originally equipped
with air bags 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
for your safety and that of your passen-
gers that you replace deployed air bags
and repair any malfunctioning air bags
to make sure the vehicle will continue
to provide supplemental crash protec-
tion for occupants.

67 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 air bags are de-
ployed:


in the event of certain frontal impacts


if impact exceeds a preset deployment
threshold


independently of the side impact
air bags
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 passenger front air bag will only be de-
ployed if:


the front passenger seat is occupied


the 58 indicator lamp in the
lower part of the front center console is
not lit (
page 74)


the impact exceeds a preset deploy-
ment threshold Side impact air bags
1Side impact air bags
!Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front or side
impact air bag on the front passenger
side to deploy in a crash which exceeds
the system's deployment threshold.

68 Safety and SecurityOccupant safetyThe side impact air bags are deployed:

in impacts exceeding a preset deploy-
ment threshold


on the impacted side of the vehicle


independently of the front air bags
The side impact air bags are not deployed
in impacts which do not exceed the sys-
tem’s deployment threshold.
The front passenger side impact air bag
will only deploy if the system senses that
the front passenger seat is occupied.
Window curtain air bags
1Window curtain air bagThe side window curtain air bags are de-
ployed:


in impacts exceeding a preset deploy-
ment threshold


on the impacted side of the vehicle


independently of the front air bags


in certain vehicle rollovers
The side window curtain air bags are not
deployed in impacts which do not exceed
the system’s deployment threshold.
The window curtain air bags fill up the area
between the A and C pillars (see arrows).
Seat belts
When the engine is started, the seat belt
telltale< illuminates to remind you and
your passengers to fasten your seat belts.
If the driver’s seat belt is not fastened be-
fore the engine is started, the seat belt
telltale< illuminates and a warning
chime sounds for approximately six sec-
onds when the engine is started.
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 45).

70 Safety and SecurityOccupant safetyWarning!
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,
passenger 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 sys-
tem is designed to enhance the protec-
tion offered to properly belted
occupants in certain frontal (front
air bags and ETD) and side (side impact,
window curtain air bags and ETD) im-
pacts which exceed preset deployment
thresholds and in certain
rollovers (window curtain air bags and
ETD).


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 a time. Do not fasten a seat
belt around a person and another per-
son or other objects.

71 Safety and Security
Occupant safety
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency ten-
sioning devices and belt force limiters.
The ETD is designed to activate in the fol-
lowing cases:

in frontal or rear-end impacts exceed-
ing a preset severity level


in certain vehicle rollovers


if the restraint systems are operational
and functioning correctly, see 1 in-
dicator lamp (
page 62).
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.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.


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, dashboard or on the seat. Always
keep both feet on the floor in front of the
seat.
iThe ETDs for the front seats will only
activate if the respective front seat belt
is fastened (latch plate properly insert-
ed into buckle).
The ETDs for the rear outer seats will
activate with or without the respective
seat belt fastened.
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 air bag on the front passenger
side to deploy in a crash which exceeds
the system's deployment threshold.

110 Controls in detailLocking and unlockingPower closing assist for doors and trunk lid
It is not necessary to slam the door or
trunk lid closed. A pneumatic power-as-
sisted mechanism draws doors and trunk
lid closed quietly and automatically once
door and trunk lid has been latched. When
the pneumatic power-assisted mechanism
has stopped, doors and/or trunk can be
re-opened.Power closing assist for doors

wheels are turning at speeds of approxi-
mately 9 mph (15 km/h) or more.
You can open a locked door from the in-
side. Open door only when conditions are
safe to do so.
You can deactivate the automatic locking
using the control system (
page 162).
Warning!
G
To prevent possible personal injury, always
keep hands and fingers away from the door
or trunk opening when closing a door or the
trunk lid. Be especially careful when small
children are around.
In case of danger, pull the inside or outside
door handle, or press the trunk lid lock.
To prevent personal injury, never actuate
the closing assist mechanism by tampering
with the door or trunk lid latch.
Warning!
G
Only drive with the doors closed. Otherwise,
one or more of the doors could open while
the vehicle is in motion, putting you and/or
others at risk.Warning!
G
Only drive with the trunk closed as, among
other dangers such as visibility blockage,
exhaust fumes may enter the vehicle interi-
or.
iThe doors unlock automatically after an
accident if the force of the impact ex-
ceeds a preset threshold. The vehicle
locks automatically when the ignition is
switched on and the wheels are turning
at vehicle speeds of approximately
9 mph (15 km/h) or more. You could
therefore lock yourself out when the
vehicle

is pushed or towed


is on a test stand
