Proper use
GWARNING
There are various warning stickers affixed to
your vehicle. Their purpose is to alert you and
others to various dangers. Therefore, do not
remove any warning stickers unless the
sticker clearly states that you may do so.
If you remove any warning stickers, you or
others could fail to recognize certain dangers
and be injured.
The proper use of the vehicle requires that
you familiarize yourself with the following
information and rules:
R safety notes in this Operator's Manual
R technical data in this Operator's Manual
R traffic rules and regulations
R laws and safety standards pertaining to
motor vehicles
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 rectified. If the problem is not resolved to
your satisfaction, please discuss the problem
again with the Mercedes-Benz Center or
contact us at one of the following addresses.

Limited Warranty
! Follow the instructions in this manual
about the proper operation of your vehicle
as well as about possible vehicle damage.
Damage to your vehicle that arises from
culpable contraventions against these
instructions are not covered either by
Mercedes-Benz Limited Warranty or by the
New or Used-Vehicle Warranty of
Daimler AG.
Data stored in the vehicle
Information about electronic data
acquisition in the vehicle
( Including notice pursuant to California Code
§ 9951)
Your vehicle records electronic data. If your
vehicle is equipped with mbrace 1
, data is
transmitted in the event of an accident.
This information helps, for example, to test
vehicle systems after an accident and to
continually improve vehicle safety.
Daimler AG can access this data and submit
it:

purposes

impairs cornering ability and reduces driving
stability. Adapt your driving style accordingly.
Have the spare wheel replaced by a normal
wheel with an M+S tire at the nearest
Mercedes-Benz Center.
Snow chains
For safety reasons, Mercedes-Benz
recommends that you only use snow chains
which have been specially approved for your
vehicle by Mercedes-Benz, or are of a
corresponding standard of quality.
! On vehicles with AIRMATIC, you must
drive at raised vehicle level if snow chains
have been mounted. The vehicle may
otherwise be damaged.
! There is not enough space for snow
chains on some wheel sizes. Observe the
information under "Tires and wheels" in the
"Technical Data" section to avoid damage
to the vehicle or the wheels.
R Only use snow chains when driving on
roads completely covered by snow. Do not
exceed the maximum permissible speed of
30 mph (50 km/h). Remove the snow
chains as soon as possible when you are no
longer driving on snow-covered roads.
R Local regulations may restrict the use of
snow chains. Applicable regulations must
be observed if you wish to mount snow
chains.
R Snow chains must not be mounted on
emergency spare wheels.
If you intend to mount snow chains, please
bear the following points in mind:
R you may not attach snow chains to all
wheel-tire combinations; see the
information under "Wheel and tire
combinations" in the "Wheels and tires"
section.
R mount snow chains only in pairs and only
to the rear wheels. Observe the
manufacturer's installation instructions.
! If snow chains are mounted on the front
wheels, the snow chains could grind
against the bodywork or components of the
chassis. This could result in damage to the
vehicle or the tires.
! Vehicles with steel wheels: if you wish
to mount snow chains on steel wheels,
make sure that you remove the respective
wheels' hubcaps first. The hubcaps may
otherwise be damaged.
i You may wish to deactivate
ESP ®
(Y page 63) when pulling away with
snow chains mounted. This way you can
allow the wheels to spin in a controlled
manner, achieving an increased driving
force (cutting action).
Tire pressure
Tire pressure specifications
GWARNING
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver's door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.
You will find a table of recommended tire
pressures on the Tire and Loading
Information placard on the B-pillar on the
Tire pressure317Wheels and tiresZ
