The towing eye can be used to pull the vehicle
onto a trailer or transporter for transporting
purposes.
X Turn the SmartKey to position 2in the
ignition lock.
X Move the selector lever to N.
As soon as the vehicle has been loaded:
X Prevent the vehicle fro mrolling away by
applying the parking brake.
X Move the selector lever to position P.
X Turn the SmartKey to position 0in the
ignition lock and remove the SmartKey
from the ignition lock.
X Secure the vehicle.
! You may only secure the vehicle by the
wheels, not by parts of the vehicle such as
axle or steering components.O therwise,
the vehicle could be damaged. Notes on 4MATIC vehicles
! Vehicles with 4MATIC must not be towed
with eithe rthe 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 position P. 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 (Y page 288).
Have the vehicle transported on a transporter
or trailer. Tow-starting (emergency engine
starting)
! Vehicles with automatic transmission
must not be started by tow-starting. This
could otherwise damage the transmission.

at (Y page 288). Fuses
Important safety notes
G
WARNING
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.
! Only use fuses that have been approved
for Mercedes-Ben zvehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or
systems could be damaged.
The fuses in your vehicle serve to close down
faulty circuits. If afuse blows, all the
components on the circuit and their functions
stop operating.
Blown fuses must be replace dwith 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-Ben zCenter. Before changing a fuse

WARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate
jacking point of the vehicle. The base of the Mounting

jack must be positioned vertically, directly
under the jacking point of the vehicle.
The following must be observed when raising
the vehicle:
R to raise the vehicle, onl yuse the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz.Ifu sed
incorrectly, the jack could tip over with the
vehicle raised.
R the jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed. It is not suited for
performing maintenance work under the
vehicle.
R avoid changing the wheel on uphill and
downhill slopes.
R before raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Never
disengage the parking brake while the
vehicle is raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, load-bearing underlay must be used.
On a slippery surface, a non-slip underlay
must be used, e.g. rubber mats.
R do not use wooden blocks or similar
objects as a jack underlay.O therwise, the
jack will not be able to achieve its load-
bearing capacity due to the restricted
height.
R make sure tha tthe distance between the
underside of the tires and the ground does
not exceed 1.2 inches (3 cm).
R never place your hands and feet under the
raised vehicle.
R never lie under the raised vehicle.
R never start the engine when the vehicle is
raised.
R never open or close a door or the trunk lid
when the vehicle is raised.
R make sure that no persons are present in
the vehicle when the vehicle is raised. !
The jack is designed exclusively for
jacking up the vehicle at the jacking points.
Otherwise, your vehicle could be damaged. X
Using lug wrench 0002, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts
completely. The jacking points are located just behind the
wheel housings of the front wheels and just
in front of the wheel housings of the rear
wheels (arrows). X

the fuel system. Even small amounts of the
wrong fuel could resul tindamage to the
fuel system and the engine. Notify a
qualified specialist workshop and have the
fuel tan kand fuel lines drained completely.
! Only refuel using unleaded gasoline with
a minimum octane rating of 91.
! Only use the fuel recommended.
Operating the vehicle with othe rfuels can
lead to engine failure.
! Do no tuse the following:
R E85 (gasoline with 85% ethanol)
R E100 (100% ethanol)
R M15 (gasoline with 15% methanol)
R M30 (gasoline with 30% methanol)
R M85 (gasoline with 85% methanol)
R M100 (100% methanol)
R Gasoline with metalliferous additives
R Diesel
Do not mix such fuels with the fuel
recommended for your vehicle. Do not use
additives. This can otherwise lead to engine
damage.T his does not include cleaning
additives for the removal and prevention of
residue build-up. gasoline may only be
mixed with cleaning additives
recommended by Mercedes-Benz; see
"Additives". You can obtain further
information from any authorized Mercedes-

! To ensure the longevity and full
performance of the engine, only premium-
grade unleaded gasoline must be used. If standard premium-grade unleaded
gasoline is unavailable and unleaded
gasoline of a lower grade is used for
refueling, 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 and engine
speeds above 3000 rpm.
R never refuel using fuel with an octane
number lower than 87. Otherwise,
engine failure could occur.
Using mixtures of methanol and ethanol is not
permitted. E10 fuel or E15 fuel (unleaded
gasoline with 10% or 15% ethanol) can be
used.
You will usually find information about the fuel
grade on the pump. If you cannot find the
label on the pump, ask the staff for
assistance.
