Operating safetyGWarning!
Work improperly carried out on electronic
components and associated software could
cause them to cease functioning. Because the
vehicle’s electronic components are
interconnected, any modifications made may
produce an undesired effect on other
systems. Electronic malfunctions could
seriously impair the operating safety of your
vehicle.
Contact an authorized Mercedes-Benz Center
for repairs or modifications to electronic
components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function while the
engine is running. You should therefore never
turn off the engine while driving.
GWarning!
Heavy blows against the vehicle underbody or
tires/wheels may cause serious damage and
impair the operating safety of your vehicle.
Such blows can be caused, for example, by
running over an obstacle, road debris or a
pothole. If you feel a sudden significant
vibration or ride disturbance, or you suspect
that damage to your vehicle as occurred:
R turn on your hazard warning flashers
R slow down carefully
R drive with caution to an area which is a safe
distance from the road
Inspect the vehicle underbody and tires/
wheels for possible damage. If the vehicle
appears unsafe, have it towed to the nearest
authorized Mercedes-Benz Center or other
qualified maintenance or repair facility for
further inspection or repairs.
Proper use of the vehicle
Proper use of the vehicle requires that you are
familiar with the following information and
rules:
R the safety precautions in this manual
R the “Technical data” section in this manual
R traffic rules and regulations
R motor vehicle laws and safety standardsGWarning!
Various warning labels are attached to your
vehicle. These warning labels are intended to
make you and others aware of various risks.
Do not remove any of these warning labels
unless explicitly instructed to do so by
information on the label itself. Removing
warning labels may cause you and others to
be unaware of certain risks which may result
in an accident and/or personal injury.
Problems with your vehicle
If you should experience a problem with your
vehicle, particularly one that you believe may
affect its safe operation, we urge you to
contact an authorized Mercedes-Benz Center
immediately to have the problem diagnosed
and corrected if required. If the matter is not
handled to your satisfaction, please discuss
the problem with the Mercedes-Benz Center
management or, if necessary, contact us at

Vehicle equipment
i This Operator’s Manual describes all
features, standard or optional, potentially
available for your vehicle at the time of
purchase. Please be aware that your
vehicle might not be equipped with all
features described in this manual.
Occupant safety
Introduction
In this section you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint systems are:
R Seat belts
R Child restraints
R
Lower Anchors and Tethers for CHildren
(LATCH)
Additional protection potential is provided by:
R
Supplemental Restraint System (SRS) with
- Air bags
- Air bag control unit (with crash sensors)
-
Emergency Tensioning Device (ETD) for
seat belts
- Seat belt force limiter
R NECK-PRO active front head restraints
R Preventive occupant safety (PRE-SAFE ®
)
R Air bag system components with
- Front passenger front air bag off
indicator lamp
- USA only: Front passenger seat with
Occupant Classification System (OCS)
- Canada only: Front passenger seat with
BabySmart™ air bag deactivation system
Although the systems are independent, their
protective functions work in conjunction with
each other.
GWarning!
Modifications to or work improperly
conducted on restraint system components
or their wiring, as well as tampering with
interconnected electronic systems, can lead
to the restraint systems no longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy
inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deployment is exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.
i See “Children in the vehicle”
( Y page 55) for information on
R infants and children traveling with you in
the vehicle
R restraint systems for infants and children
SRS indicator lamp
The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates detection of system malfunctions.
The SRS indicator lamp + in the
instrument cluster comes on when the
ignition is switched on. It goes out no later
than a few seconds after the engine has been
started.
The SRS components are in operational
readiness when the SRS indicator lamp
+ is not lit while the engine is running.
A malfunction in the system has been
detected if the SRS indicator lamp +
R fails to go out after approximately
4 seconds after the engine was started
R does not come on at all
R comes on after the engine was started or
while driving

GWarning!
The SRS self-check has detected a
malfunction when the SRS indicator lamp
+ :
R does not come on at all
R does not go out after 4 seconds after the
engine was started
R comes on while driving
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 be
activated when needed in an accident, which
could result in serious or fatal injury. The SRS
might also deploy unexpectedly and
unnecessarily which could also result in injury
as well.
In addition, improper 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.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact an authorized Mercedes-Benz Center.

Center at 1-800-FOR-MERCedes

Air bags
GWarning!
Air bags are designed to reduce the potential
of injury and fatality in certain
R frontal impacts (front air bags and driver’s
side knee bag)
R side impacts (side impact air bags and
window curtain air bags)
R rollovers (window curtain air bags)
However, no system available today can
completely eliminate injuries and fatalities.
Deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust, however, is neither harmful
to your health, nor does it indicate a fire in the
vehicle. The dust might cause some
temporary 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.GWarning!
To reduce the risk of injury when the front air
bags inflate, it is very important for the driver
and front passenger to always be in a properly
seated position and to wear their respective
seat belt.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the seat backrest.
Fasten your seat belt and make sure it is
properly positioned on your body.
Since the air bag inflates with considerable
speed and force, a proper seating position
and correct positioning of the hands on the
steering wheel will help to keep you at a safe
distance from the air bag. Occupants who are
not wearing their seat belt, are not seated
properly or are too close to the air bag can be
seriously injured or killed by an air bag as it
inflates with great force instantaneously:
R Sit with the seat belt properly fastened in a
position that is as upright as possible with
your back against the seat backrest.
R Move the driver’s seat as far back as
possible, still permitting proper operation
of vehicle controls. The distance from the
center of the driver’s chest 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
adjusting the seat and steering wheel. If
