Cleaning the plastic trim
GWARNING
Care products and cleaning agents containing
solvents cause surfaces in the cockpit to
become porous. As a result, plastic parts may
come loose in the event of air bag
deployment. There is a risk of injury.
Do not use any care products and cleaning
agents to clean the cockpit.
!Do not affix the following to plastic
surfaces:
Rstickers
Rfilms
Rscented oil bottles or similar items
You can otherwise damage the plastic.
!Do not allow cosmetics, insect repellent
or sunscreen to come into contact with the
plastic trim. This maintains the high-quality
look of the surfaces.
XWipe the plastic trim with a damp, lint-free
cloth, e.g. a microfiber cloth.
XHeavy soiling:use care and cleaning
products recommended and approved by
Mercedes-Benz.
The surface may change color temporarily.

Useful information
iThis Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
iRead the information on qualified
specialist workshops: (Ypage 28).
Where will I find...?
Vehicle tool kit
General notes
The vehicle tool kit can be found in the
stowage well under the cargo compartment
floor.
iApart from certain country-specific
variations, the vehicles are not equipped
with a tire-change tool kit. Some tools for
changing a wheel are specific to the
vehicle. For more information on which
tools are required to perform a wheel
change on your vehicle, consult a qualified
specialist workshop.
Tools required for changing a wheel may
include, for example:
RJack
RWheel chock
RLug wrench
RRatchet wrench
RAlignment bolt
Vehicles with a TIREFIT kit
CLug wrench
DTowing eye

If the pressure loss warning message
appears in the multifunction display:
RObserve the instructions in the display
messages (Ypage 318).
RCheck the tire for damage.
RIf driving on, observe the following notes.
The maximum driving distance is
approximately 50 miles (80 km) when the
vehicle is partially laden and approximately
18 miles (30 km) when the vehicle is fully
laden.
In addition to the vehicle load, the driving
distance possible depends upon:
RSpeed
RRoad condition
ROutside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving
conditions/maneuvers, or it can be increased
through a moderate style of driving.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tire pressure loss warning
appears in the multifunction display.
You must not exceed a maximum speed of
50 mph (80 km/h).
iWhen replacing one or all tires, make sure
that you use only tires:
Rof the size specified for the vehicle and
Rmarked "MOExtended"
If a tire has gone flat and cannot be
replaced with a MOExtended tire, a
standard tire may be used as a temporary
measure. Make sure that you use the
proper size and type (summer or winter
tire).
iVehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the
factory. It is therefore recommended that
you additionally equip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
A TIREFIT kit may be obtained from a
qualified specialist workshop.
Important safety notes
GWARNING
When driving in emergency mode, the driving
characteristics deteriorate, e.g. when
cornering, accelerating quickly and when
braking. There is a risk of an accident.

Information on 4MATIC vehicles
!Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised,
as doing so will damage the transmission.
If the vehicle has transmission damage or
damage to the front or rear axle, have it
transported on a transporter or trailer.
In the event of damage to the electrical
system
If the battery is defective, the automatic
transmission will be locked in positionP. To
shift the automatic transmission to position
N, you must provide power to the vehicle's
electrical system in the same way as when
jump-starting (Ypage 395).
Have the vehicle transported on a transporter
or trailer.
Recovering a vehicle that has become
stuck
!When recovering a vehicle that has
become stuck, pull it as smoothly and
evenly as possible. Excessive tractive
power could damage the vehicles.
If the drive wheels have become stuck in
loose or muddy ground, pull the vehicle out
with extreme caution, especially so if the
vehicle is loaded.
Never attempt to recover a vehicle with a
trailer attached.
Pull out the vehicle backwards, if possible
using the tracks it made when it became
stuck.
Tow-starting (emergency engine
starting)
!Vehicles with automatic transmission
must not be tow-started. You could
otherwise damage the automatic
transmission.
iYou can find information on "Jump-
starting" under (Ypage 395).
Fuses
Important safety notes
GWARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher
amperage, the electric cables could be
overloaded. This could result in a fire. There
is a risk of an accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
!For the fuse boxes in the engine
compartment and under the rear bench
seat, only use fuses with the suffix "S".
Otherwise, components or systems could
be damaged.
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the
components on the circuit and their functions
stop operating.
Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed
in the fuse allocation chart.
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
Before changing a fuse

Operation
Information on driving
If the vehicle is heavily loaded, check the tire
pressures and correct them if necessary.
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the wheels or tires are damaged. If you
suspect that a tire is defective, reduce your
speed immediately. Stop the vehicle as soon
as possible to check the wheels and tires for
damage. Hidden tire damage could also be
causing the unusual handling characteristics.
If you find no signs of damage, have the tires
404Operation
Wheels and tires

and wheels checked at a qualified specialist
workshop.
When parking your vehicle, make sure that
the tires do not get deformed by the curb or
other obstacles. If it is necessary to drive over
curbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle.
Otherwise, the tires, particularly the
sidewalls, may be damaged.
Regular checking of wheels and tires
GWARNING
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle. There is a risk of
accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Regularly check the wheels and tires of your
vehicle for damage at least once a month, as
well as after driving off-road or on rough
roads. Damaged wheels can cause a loss of
tire pressure. Pay particular attention to
damage such as:
Rcuts in the tires
Rpunctures
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width
of the tire (Ypage 405). If necessary, turn
the front wheels to full lock in order to inspect
the inner side of the tire surface.
All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
mount anything onto the valve other than the
standard valve cap or other valve caps
approved by Mercedes-Benz for your vehicle.
Do not use any other valve caps or systems,
e.g. tire pressure monitoring systems.
Regularly check the pressure of all the tires
particularly prior to long trips. Adjust the tire
pressure as necessary (Ypage 408).
Observe the notes on the emergency spare
wheel (Ypage 439).
The service life of tires depends on the
following factors amongst other things:
RDriving style
RTire pressure
RDistance covered
Important safety notes on the tire
tread
GWARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where
speed is not adapted to suit the driving
conditions. There is a risk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at
different locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
RSummer tires:

Only winter tires bearing theMsnowflake
symbol in addition to the M+S marking
provide the best possible grip in wintry road
conditions.
Only these tires will allow driving safety
systems such as ABS and ESP®to function
optimally in winter. These tires have been
developed specifically for driving in snow.
Use M+S tires of the same make and tread on
all wheels to maintain safe handling
characteristics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
Once the winter tires are mounted:
XCheck the tire pressures (Ypage 411).
XRestart the tire pressure monitor
(Ypage 412).
XVehicles for Canada:restart the tire
pressure loss warning system
(Ypage 412).
For more information on driving with the
emergency spare wheel, see (Ypage 439).
Snow chains
GWARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident.
To avoid hazardous situations:
Rnever install snow chains to the front
wheels
Ralways install snow chains in pairs to the
rear wheels.
!You must drive at raised vehicle level
(height 1) if snow chains have been
installed. The vehicle may otherwise be
damaged.
!Vehicles with Adaptive Damping
System (ADS):do not use the sports mode
if you have installed snow chains. The
vehicle may otherwise be damaged.
!On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and
tire combinations" section under "Tires and
wheels".
For safety reasons, Mercedes-Benz
recommends that you only use snow chains
that have been specially approved for your
vehicle by Mercedes-Benz, or are of a
corresponding standard of quality.
If you intend to mount snow chains, please
bear the following points in mind:
ROnly use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as
possible when you come to a road that is
not snow-covered.
RDo not exceed the maximum permissible
speed of 30 mph (50 km/h).
RLocal regulations may restrict the use of
snow chains. Observe the appropriate
regulations if you wish to mount snow
chains.
RSnow chains may not be mounted on all
wheel/tire combinations. Permissible
wheel-tire combinations (Ypage 432).
iYou may wish to deactivate ESP®
(Ypage 73) when pulling away with snow
chains installed. You can thereby allow the
wheels to spin in a controlled manner,
achieving an increased driving force
(cutting action).
For more information on driving with the
emergency spare wheel, see (Ypage 439).
