12 IntroductionWhere to find it
Where to find itThis Operator’s Manual is designed to pro-
vide comprehensive support information
for you, the vehicle operator. For you to
find information quickly 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
Here you will find all the information you
need for your first drive. You should read
this section first if this is your first
Mercedes-Benz vehicle or if you are rent-
ing or borrowing this vehicle.Safety and Security

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 vehi-
cle.Practical hints
This section provides fast assistance for
dealing with problems you may encounter.
Technical data
All important technical data for your vehi-
cle 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
the Service Booklet
Separate operating instructions will be
provided as required depending on the
equipment options installed in your vehi-
cle.
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.
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.
96 Controls in detailSeatsSeat ventilation*
The switch is located on the door. The blue
indicator lamps on the switch show the
ventilation level selected:

iIn normal operation the seat ventilation
will switch off automatically after about
30 minutes.
!If one or all of the lamps blink on the
seat ventilation* switch, there is insuf-
ficient voltage since too many electri-
cal consumers are switched on. The
seat ventilation* switches off automat-
ically.
The seat ventilation* will switch back
on again automatically as soon as suffi-
cient voltage is available.

Leather upholstery
Using aftermarket seat covers or wearing
clothing that have the tendency to give off
coloring (e.g. when wet, etc.) may cause
the upholstery to become permanently dis-
colored. By lining the seats with a proper
intermediate cover, contact-discoloration
will be prevented.
Wipe leather upholstery with a damp cloth
and dry thoroughly or clean with
Mercedes-Benz approved Leather Care. Ex e r c i s e p a r t i cu l a r c a r e w h e n cl e a n i n g p e r -

Possible cause
Suggested solution
?
The yellow CHECK ENGINE mal-
function indicator lamp comes
on while driving.
There is a malfunction in:
The fuel injection system
The ignition system
The emission control system
Systems which effect emissions
Such malfunctions may result in excessive
emissions values and may switch the engine
to its limp-home (emergency operation)
mode.
Have the vehicle checked as soon as
possible by an authorized
Mercedes-Benz Center.
An on-board diagnostic connector is
used by the service station to link the
vehicle to the shop diagnostics sys-
tem. It allows the accurate identifica-
tion of system malfunctions through
the readout of diagnostic trouble
codes. It is located in the front left
area of the footwell next to the park-
ing brake.
The fuel cap is not closed tightly.
Check the fuel cap.
Your gas tank is empty.
After refuelling, start the engine three
or four times in succession.
The limp-home mode is canceled. You
do not need to have your vehicle
checked.
