18 Introduction
Where to find it
This Operator’s Manual is designed to pro-
vide comprehensive support information
for you, the vehicle operator. Each section
has its own reference color.
At a glance
Here you will find an overview of all the
controls that can be operated from the
driver’s seat.
Getting started

and security features in your vehicle.
Controls in detail
Here you will find detailed information
about the equipment installed on your ve-
hicle. This section expands on the “Getting
started” section and also describes techni-
cal innovations. If you are already familiar
with the basic functions of your vehicle,
this section will be of particular interest to
you.
Operation
Here you will find all the information you
need for the proper operation of your
vehicle.
Practical hints
This section provides fast assistance for
dealing with problems you may encounter.
Technical data
All important technical data for your
vehicle can be found in this section.
Indexes
The glossary provides explanations of the
most important technical terms.
The table of contents and the index are de-
signed to help you find information quickly
and easily.
The following publications are part of your
vehicle documentation:

this Operator’s Manual

45 Getting started
Driving
Driving
Fastening the seat belts
Warning!G
Make sure that absolutely no objects are ob-
structing the pedal’s range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure the pedals still have
sufficient clearance.
During sudden driving or braking maneu-
vers, the objects could get caught between
the pedals. You could then no longer brake
or accelerate. This could lead to accidents
or injury.Warning!G
Always fasten your seat belt before driving
off. Always make sure your passenger is
properly restrained.
Failure to wear and properly fasten and
position your seat belt greatly increases
your risk of injuries and their likely severity
in an accident. You and your passenger
should always 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 wearing your
seat belt. The air bags can only provide the
protection they were designed to afford if
the occupants are using their seat belts
(
page 71).
Warning!G
Children 12 years old and under must be
seated and properly secured in an appropri-
ate infant, or toddler restraint, or booster
seat recommended for the size and weight
of the child. For additional information, see
“Children in the vehicle” (
page 75).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.

46 Getting started
Driving
1Seat belt holder
2Latch plate
3Buckle
4Release button
With a smooth motion pull the belt
from seat belt holder1.
Place the shoulder portion of the belt
across the top of your shoulder and the
lap portion across your hips.
Push latch plate2 into buckle3 until
it clicks.
If necessary, tighten the lap portion to
a snug fit by pulling shoulder portion
up.
Proper use of seat belts

Do not twist the seat belt when
fastening.

Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck). Never pass the
shoulder portion of the seat belt under
your arm.

Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.
Warning!G
Never let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use a seat belt for more than one person at
a time.
Warning!G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a nearly upright position and the
belt is properly positioned on the body.
Warning!G
Read and observe the additional warning no-
tices printed in the “Safety and Security”
(
page 64) and (page 71).

47 Getting started
Driving

Place the seat backrest in a nearly up-
right position.

Never use a seat belt for more than one
person at a time.

Do not fasten a seat belt around a per-
son and another object at the same
time. When using a seat belt to secure
infant or toddler restraints or children
in booster seats, always follow the
child seat manufacturer’s instructions.

Check your seat belt during travel to
make sure that it is properly
positioned.

Make sure that the seat belt is always
fitted snugly. Take special care of this
when wearing loose clothing.
Starting the engine
Warning!G
Do not pass belts over sharp edges. They
could tear.
Do not allow the seat belt to get caught in
the door or in the seat adjustment mecha-
nism. This could damage the seat belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness 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.
Damaged seat belts or seat belts that were
highly stressed in an accident must be
replaced. Contact an authorized
Mercedes-Benz Center.Warning!G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the engine in confined areas
(such as garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open.

60 Safety and Security
Occupant safety
In this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are

Seat belts (page 71)

Child restraints (page 76)
Additional protection potential provided by

Supplemental Restraint System (SRS)
with

Air bags (page 62)

Air bag control unit
(with crash sensors)

Emergency Tensioning Device
(ETD) for seat belts (
page 74)

Seat belt force limiter (page 74)Air bag system components with

Passenger front air bag off indicator
lamp (
page 70)

Passenger seat with Occupant Classifi-
cation S
ystem (OCS) (page 67)
Although independent systems, their
protective functions work in conjunction
with each other.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 malfunctions. The
1indicator lamp in the instrument
cluster comes on when the ignition is
switched on and goes out no later than a
few seconds after the engine has been
started.
The SRS components are in operational
readiness if the 1indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the 1indicator lamp:

fails to go out after approximately
4 seconds after the engine was started

does not come on at all

comes on after the engine was started
or while driving
For more information, see the “Practical
hints” section (
page 310).
iFor information on infants and children
traveling with you in the vehicle and restraint
systems for infants and children, see “Children
in the vehicle” (
page 75).

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.
