Warning!
G
When leaving the vehicle, always remove the
key from the starter switch, take the
KEYLESS-GO
* card (if so equipped) with
you, and lock your vehicle. Do not leave chil-
dren unattended in the vehicle, or with ac-
cess to an unlocked vehicle. Unsupervised
use of vehicle equipment may cause an ac-
cident and/or serious personal injury.

52 Safety and SecurityOccupant safety
Occupant safetyIn this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are

Seat belts


Emergency tensioning device


Airbags


Child seats


Child seat recognition
As independent systems their protective
effects work in conjunction with each oth-
er.The
1
warning lamp in the instrument
cluster lights up for about 4 seconds when
you turn the key in the starter switch to po-
sition 1 or 2, or press the KEYLESS-GO* (if
so equipped) start/stop button once or
twice. It goes out when you start the en-
gine. This shows that the restraint systems
are operational.
If the lamp does not come on at all or if it
fails to extinguish after approximately 4
seconds or if it comes on thereafter, a mal-
function in the system has been detected.
More information can be found in the
"Practical hints" section (
page 252).
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 62).
Warning!
G
In the event that the SRS malfunction indica-
tor lamp lights up during driving or does not
come on at all, the SRS may not be opera-
tional. For your safety, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not be activated when needed in an acci-
dent, which could result in serious or fatal
injury, or it might deploy unexpectedly and
unnecessarily which could also result in inju-
ry.
Improper work on the restraint systems can
lead to unintentional deployment or opera-
tional failure.
In addition, through improper work there is
a risk of rendering the SRS inoperative or
causing unintended airbag deployment.
Work on the SRS must therefore only be per-
formed by an authorized Mercedes-Benz
Center.

53 Safety and Security
Occupant safety
AirbagsWarning!
G
Airbags are designed to reduce the potential
for injury resulting from certain frontal im-
pacts (front airbags, driver-side kneebag) or
side impacts (head-thorax airbags) which
may cause significant injuries. However, no
system available today can totally eliminate
injuries and fatalities.
The activation of the SRS temporarily releas-
es a small amount of dust from the airbags.
This dust, however, is neither injurious to
your health, nor does it indicate a fire in the
vehicle. The dust might cause some tempo-
rary breathing difficulty for people with asth-
ma 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 airbag inflates, then get
fresh air by opening a window or door.
Warning!
G
To reduce the risk of injury when the front
airbags inflate, it is very important for the
driver and passenger to always be in a prop-
erly seated position and to wear your 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 ensure that it is properly
positioned on your body (
page 37).
Since the airbag 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 airbag. Oc-
cupants who are unbelted, out of position or
too close to the airbag can be seriously in-
jured by an airbag as it inflates with great
force in the blink of an eye:


Sit properly belted in an upright position
with your back against the seat back-
rest.


Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the airbag cover on
the steering wheel must be at least ten
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 your authorized
Mercedes-Benz Center.


Do not lean with your head or chest
close to the steering wheel or dash-
board.


Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand / arm injury
when driver front airbag inflates.


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

54 Safety and SecurityOccupant safety

Occupants, especially children, should
never lean their heads in the area of the
door where the head-thorax airbag in-
flates. This could result in serious inju-
ries or death should the airbag be
triggered. Always sit upright, properly
use the seat belts and appropriate size
infant or child restraint system.


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 vehicle to deacti-
vate the passenger side front airbag
when it is properly installed. Otherwise
they will be struck by the airbag when it
inflates in a crash. If this happens, seri-
ous or fatal injury will result.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle you are responsible
to make the buyer aware of these points. Be
sure to give the buyer this Operator’s Manu-
al.
Warning!
G
Should you choose to place a child 12 years
old or under in the passenger seat of your
vehicle, you must properly use a
BabySmart
TM child restraint which will turn
off the passenger side front airbag
(
page 62). BabySmart
TM will not, howev-
er, turn off any side impact airbag.
It should be noted, however, that there is a
possibility for a head-thorax airbag related
injury if occupants, especially children, are
not properly seated or restrained when next
to a head-thorax airbag which needs to de-
ploy 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 airbag inflates. This could
result in serious injuries or death should
the head-thorax airbag be activated.
(2) Always sit upright, properly use the seat
belts and use an appropriately sized in-
fant or child restraint system for all chil-
dren 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
passenger seat occupants to have the pas-
senger side head-thorax airbag deactivated,
then deactivation can be accomplished
upon your written election to do so at your
authorized Mercedes-Benz Center at an ad-
ditional cost. Please contact your local au-
thorized Mercedes-Benz Center or call our
Customer Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372)
for details.

57 Safety and Security
Occupant safety
When an airbag deploys, a small amount of
dust is released while inflating. This dust is
neither injurious to your health, nor does it
indicate a fire in the vehicle.
The textile texture of the airbags can cause
light skin abrasions due to the speed of in-
flation.
Front airbags
Driver and passenger airbags are de-
ployed:

in the event of a frontal impact


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 64)
1Driver airbag
2Passenger airbag
3KneebagKneebag
The kneebag 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 kneebag 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 or side im-
pact airbag on the front passenger side
to deploy in a crash which exceeds the
system's deployment threshold.

58 Safety and SecurityOccupant safetyHead-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
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 provinc-
es. Even where this is not the case, all ve-
hicle occupants 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 37).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 62).
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 53).

60 Safety and SecurityOccupant safety
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts are equipped with emergen-
cy tensioning devices, belt force limiters,
and automatic comfort-fit.
The ETD is designed to activate in the fol-
lowing cases when the seat belts are fas-
tened:

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


if the restraint systems are operational
and functioning correctly, see
1
in-
dicator lamp (
page 52).
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.
The automatic comfort-fit feature reduces
the retracting force of the seat belts when
they are in normal use.


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.


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.

69 Safety and Security
Driving safety systems
The
-
warning lamp in the speedome-
ter (
page 21) lights up when you turn the
key to position1 or2. It goes out when the
engine is running.
Flashing warning lamp while braking
The v
warning lamp flashes whenever
the ABS is activated. Always adapt your
driving style to the prevailing road and
weather conditions.

When the ABS is in the regulating
mode, continue to apply pressure on
the brake pedal.
BAS
The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost thereby potential-
ly reducing the braking distance. Apply
continuous full braking pressure until the
emergency braking situation is over. The
ABS will prevent the wheels from locking.
When you release the brake pedal the
brakes function again as normal. The BAS
is then deactivated.
Warning!
G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction af-
forded. The ABS cannot prevent accidents,
including those resulting from excessive
speed in turns, following another vehicle too
closely, or aquaplaning. Only a safe, atten-
tive, and skillful driver can prevent acci-
dents. The capabilities of an ABS equipped
vehicle must never be exploited in a reck-
less or dangerous manner which could jeop-
ardize the user’s safety or the safety of
others.
