Product information
We recommend using genuine Mercedes-
Benz parts as well as conversion parts and
accessories explicitly approved by us for your
vehicle model.
We have tested these parts to determine their
reliability, safety and special suitability for
Mercedes-Benz vehicles. Despite ongoing
market research, Mercedes-Benz is unable to
assess other parts. We cannot therefore be
held responsible for them, even if in individual
cases an official approval or authorization by
governmental or other agencies should exist.
The use of non-approved parts could affect
your vehicle's operating safety. Mercedes-
Benz therefore recommends that you use
genuine Mercedes-Benz parts, conversion
parts and accessories that have been
approved for the type of vehicle. Genuine
Mercedes-Benz parts, approved conversion
parts and accessories are available from any
authorized Mercedes-Benz Center. In
addition, you will receive advice about
permissible technical modifications, and the
parts will be professionally installed.
Operator's Manual
Notes on the Operator's Manual
This Operator's Manual contains a great deal
of helpful information. We urge you to read it
carefully and familiarize yourself with the
vehicle before driving.
For your own safety and longer service life of
the vehicle, we urge you to follow the
instructions and warnings contained in this
Operator's Manual. Ignoring them could
result in damage to the vehicle or personal
injury to you or others. Vehicle damage
caused by failure to follow instructions is not
covered by the Mercedes-Benz Limited
Warranty.
Vehicle equipment
This manual describes all the standard and
optional equipment of your vehicle available
at the time of publication of the Operator's
Manual. Country-specific differences are
possible. Note that your vehicle may not be
equipped with all functions described. This
also refers to safety-related systems and
functions. The equipment in your vehicle may
therefore differ from that shown in the
descriptions and illustrations. All the systems
found in your vehicle are listed in the original
purchase agreement of your vehicle. Should
you have any questions concerning
equipment and operation, please consult an
authorized Mercedes-Benz Center.
The Operating Instructions and the
Maintenance Booklet are important
documents and should be kept in the vehicle.
Service and vehicle operation
Service and literature
The Service and Warranty Information
booklet contains detailed information about
the warranties covering your vehicle. Your
authorized Mercedes-Benz Center will
replace and repair any factory-fitted parts
based on the terms and conditions of the
following warranties:
R New Vehicle Limited Warranty
R Emission System Warranty
R Emission Performance Warranty
R California, Connecticut, Maine,
Massachusetts, New York, Pennsylvania,
Rhode Island and Vermont
R State Warranty Enforcement Laws (Lemon

situations (on vehicles with DISTRONIC
PLUS)
R in critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely
or when having to swerve to avoid an
obstacle at a speed above 85 mph
(140 km/h).
PRE-SAFE ®
takes the following measures
depending on the hazardous situation
detected:
R the front seat belts are pre-tensioned.
R under accident conditions, the front-
passenger seat is adjusted if it is in an
unfavorable position.
R increases the air pressure in the side
bolsters of the seat cushion and seat
backrest of the active multicontour seats in
the front.
R if the vehicle skids, the sliding roof with
power tilt/sliding panel and the side
windows are closed so that only a small gap
remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. The air pressure in the
side bolsters on the active multicontour seat
is reduced again. All settings made by PRE-
SAFE ®
can then be reversed.
If the seat belts are not released:XWhen the vehicle is stationary, move the
backrest or seat back slightly.
The belt pretensioning is reduced and the
locking mechanism is released.GWarning
Make sure that nobody can become trapped
as you adjust the seat.
! Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
More information about belt adjustment, a
convenience function integrated into PRE-
SAFE ®
, can be found in the "Belt adjustment"
section ( Y page 56).
NECK-PRO head restraints
The NECK-PRO head restraints increase
protection for the driver's and front-
passenger's head and neck. In the event of a
rear collision of a certain severity, the NECK-
PRO head restraints on the driver's and front-
passenger seats are moved forwards and
upwards. This provides better head support.
GWarning
Do not secure any objects (e.g. coat hangers)
on the NECK-PRO head restraints. Otherwise,
the NECK-PRO head restraints may not
function properly, or in the event of a rear-end
collision may not be able offer the level of
protection they are designed to provide.
GWarning
Only use seat covers/head restraint covers
that have been tested and approved by
Mercedes-Benz for your model.
Using seat covers and head restraint covers
other than those recommended may cause a
malfunction when NECK-PRO head restraints
are triggered or front side impact air bags/
pelvis air bags may be prevented from
deploying.
Contact an authorized Mercedes-Benz Center
for availability.
If the NECK-PRO head restraints have been
triggered in an accident, you must reset the
NECK-PRO head restraints on the driver's and
front-passenger seat ( Y page 53).
Otherwise, the additional protection will not
be available in the event of another rear-end
collision. You can recognize that NECK-PRO
head restraints have been triggered by the
fact that they have moved forwards and can
no longer be adjusted.

Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.
Exterior lighting
Important safety notes
For reasons of safety, Mercedes-Benz
recommends that you drive with the lights
switched on even during the daytime. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations. In these countries, the daytime
running lamps are automatically switched on
when the engine is started.
Notes on driving abroad
Converting to symmetrical low beam
when driving abroad: switch the headlamps
to symmetrical low beam in countries in
which traffic drives on the opposite side of the
road to the country where the vehicle is
registered. This prevents oncoming traffic
from being dazzled. Symmetrical lights do not
illuminate as large an area of the edge of the
road.
Have the headlamps converted at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center, as close to the border
as possible before driving in these countries.
Converting to asymmetrical low beam
after returning: have the headlamps
converted back to asymmetrical low beam at
a qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center, as soon as
possible after crossing the border when
returning.

Important safety notes
GWarning!
Gasoline and diesel fuels are highly flammable
and poisonous. They burn violently and can
cause serious injury.
Never allow sparks, flames or smoking
materials near gasoline or diesel fuel!
Turn off the engine before refueling.
Whenever you are around gasoline or diesel
fuel, avoid inhaling fumes and any skin or
clothing contact. Extinguish all smoking
materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging your
health.
GWarning
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gasoline
to spray back out when removing the fuel
pump nozzle, which could cause personal
injury.
