instructions.
Cross bar
Points to observe before use
The maximum roof load that can be used with
additional accessories decreases by the dead
weight of the crossbars (13.7 lbs/6.2 kg).
! Note that installing the crossbar
increases the vehicle height by 50 mm
compared to the height stated in the
"Technical data" section.
The wrench and the Allen key are located with
the vehicle tool kit in the stowage space
underneath the trunk floor ( Y page 314).
i Replacement parts are available as
Mercedes-Benz accessories. Contact your
authorized Mercedes-Benz Service Center.
Installing the crossbars
GWARNING
Please follow these installation instructions
carefully. Caution should be exercised to
avoid damage to the vehicle while installing
the crossbars. Also, be careful not to injure
yourself or others while installing and
adjusting the crossbars or loading items on
them.
Each individual step of the installation
instructions, the warning notices, the general
safety precautions and the instructions for
use must be followed exactly. If the crossbars
are not mounted correctly, they and the
objects attached to them could come loose
from your vehicle and cause an accident,
thereby injuring you and other persons and/
or causing damage to property, including
damage to your vehicle.
GWARNING
Every time the crossbars are mounted, before
you set off on a journey and periodically
during longer journeys, check all the screws
on the crossbars to make sure that they are
secure, and tighten them if necessary. Repeat
these checks at regular intervals as road-
surface conditions dictate, and at least after
every 1500 miles (2500 km) of continuous
use.
Otherwise, the crossbars, mounted
accessories and the objects attached to them
could come loose from the vehicle causing an
accident, thereby injuring you and other
persons and/or causing damage to property,
including damage to your vehicle.
Do not use lubricant on the screws of the
crossbars. The screws could work loose and
the crossbars could become detached from
your vehicle, together with the objects
attached to them causing an accident,
thereby injuring you and other persons and/
or causing damage to property, including
damage to your vehicle.GWARNING
Only install the crossbars at the exact
locations designated on the roof rails. The
designated locations for the front crossbars
are between the markings engraved on the
inside of the roof rails. The designated
locations for the rear crossbars are between
the gaps on the roof rails.
Otherwise, the crossbars, mounted
accessories and the objects attached to them
could come loose from the vehicle causing an
accident, thereby injuring you and other
persons and/or causing damage to property,
including damage to your vehicle.
GWARNING
A roof load creates a greater surface area
exposed to the wind and causes the vehicle
to have a higher center of gravity, thereby
changing the vehicle's driving characteristics.
Accordingly, the additional weight on the roof
of the vehicle can have a detrimental effect
on braking, cornering and acceleration.
Never exceed the maximum permissible roof
load or the maximum permissible vehicle
278Stowage areasStowing and features

Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
Once you have mounted the winter tires:XCheck the tire pressures ( Y page 345).XRestart the tire pressure monitor
( Y page 347).GWARNING
If you use your spare wheel when M+S tires
are mounted on the other wheels, be aware
that the difference in tire characteristics
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.
! Vehicles with the Adaptive Damping
System (ADS): do not drive in ADS SPORT
mode 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 install snow chains to 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 69) 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,

Important safety notesGWARNING
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.
Premium-grade unleaded gasoline
! To ensure the longevity and full
performance of the engine, only premium-
grade unleaded gasoline must be used.
If no premium-grade unleaded gasoline is
available and regular unleaded gasoline
must be used, observe the following
precautions:
R only fill the fuel tank to half full with
regular unleaded gasoline and fill the rest
with premium-grade unleaded gasoline
as soon as possible.
R do not drive at the maximum speed.
R avoid sudden acceleration.
R when the vehicle is carrying a light load,
e.g. two passengers without luggage, do
not allow the engine to rev above
3000 rpm.
R when the vehicle is fully loaded or in
mountainous terrain, do not depress the
accelerator pedal further than ⅔ of the
pedal travel.
Fuel requirements
Gasoline engines
Use only premium-grade unleaded gasoline.
The octane number should be at least 91.
Details can be found on the gas pump. The
octane number is the average value of the
Research Octane Number (RON) and the
