PLUG-IN HYBRID vehicles may not be towed
away but must instead be transported, if: R
the multifunction display is not working or R
the á Towing Not Permitted See
Operator's Manual message appears in the
multifunction display.
If the vehicle is in a dangerous area, it can be
towed out of that area with both axles on the
ground. In this case, the towing distance must
not be greater than 165 ft (50 m) and must not
exceed a towing speed of 6 mph (10 km/h). For
longer distances, have the vehicle loaded and
transported.
Installing/removing the towing eye
Installing the towing eye
The brackets for the screw-in towing eye are
located in the bumpers. They are at the rear and
at the front, under covers C .X
Remove the towing eye from the vehicle tool
kit/stowage tray ( Y
page 367).X
Press the mark on cover C inwards in the
direction of the arrow. X
Remove cover C from the opening.X
Screw in the towing eye clockwise as far as it
will go and tighten it. Removing the towing eye X
Unscrew and remove the towing eye. X
Attach cover C to the bumper and press until
it engages. X
Place the towing eye in the vehicle tool kit/
stowage tray.
Towing a vehicle with both axles on
the ground It is important that you observe the safety
instructions when towing away your vehicle
( Y
page 379).
The automatic transmission automatically shifts
to position P when you open the driver's or front-
passenger door or when you remove the Smart-
Key from the ignition lock.
In order to ensure that the automatic transmis-
sion stays in position N when towing the vehicle,
you must observe the following points: X
You must use the SmartKey instead of the
Start/Stop button ( Y
page 162).X
Make sure that the vehicle is stationary and
that the key is in position 0 in the ignition lock.X
Turn the SmartKey to position 2 in the ignition
lock. X
Depress and hold the brake pedal. X
Shift the automatic transmission to position
N . X
Release the brake pedal. X
Release the electric parking brake. X
Leave the SmartKey in position 2 in the igni-
tion lock. X
Switch on the hazard warning lamps
( Y
page 132).
In order to signal a change of direction when
towing the vehicle with the hazard warning
lamps switched on, use the combination switch
as usual. In this case, only the indicator lamps
for the direction of travel flash. After resetting
the combination switch, the hazard warning
lamp starts f lashing again.380

Transporting the vehicle
PLUG-IN HYBRID vehicles Transportation of the vehicle should only be car-
ried out by professional recovery companies.
4MATIC vehicles/vehicles with auto-
matic transmission
! When the vehicle is loaded for transport, the
front and rear axles must be stationary and on
the same transportation vehicle. Positioning
over the connection point of the transport
vehicle is not permitted. The drive train may
otherwise be damaged.
All vehicles
! You may only secure the vehicle by the
wheels, not by parts of the vehicle such as
axle or steering components. Otherwise, the
vehicle could be damaged.
The towing eye can be used to pull the vehicle
onto a trailer or transporter for transporting pur-
poses. X
Turn the SmartKey to position 2 in the ignition
lock. X
Shift the automatic transmission to position
N .
As soon as the vehicle has been loaded: X
Prevent the vehicle from rolling away by
applying the electric parking brake. X
Shift the automatic transmission to posi-
tion P .X
Turn the SmartKey to position 0 in the ignition
lock and remove it. X
Secure the vehicle. Notes 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.
Vehicles with 4MATIC may either be towed away
with both axles on the ground or be loaded up
and transported.
If the vehicle's transmission, front, or rear axle is
damaged, have the vehicle transported on a
truck or trailer.
In the event of damage to the electrical sys-
tem: 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 376).
Have the vehicle transported on a transporter or
trailer.
Tow-starting (emergency engine
starting)
! Vehicles with automatic transmission must
not be tow-started. You could otherwise dam-
age the automatic transmission.

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 amper-
age, 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.
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.
The fuse allocation chart is on the fuse box in the
trunk ( Y
page 381). Fuses 381
Breakdown assistance Z
To avoid hazardous situations: R
never install snow chains to the front
wheels R
always install snow chains in pairs to the
rear wheels.
For safety reasons, Mercedes-Benz recom-
mends 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: R
Snow chains may not be mounted on all
wheel/tire combinations. Permissible wheel-
tire combinations ( Y
page 410).R
Only 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. R
Local regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains. R
Do not exceed the maximum permissible
speed of 31 mph (50 km/h). R
On vehicles with AIRMATIC ( Y
page 212) or
Magic Body Control (MBC) ( Y
page 210), you
must drive at raised vehicle level if snow
chains have been mounted. R
When snow chains are installed, never use
Active Parking Assist ( Y
page 216).
You may wish to deactivate ESP ®
when pulling
away with snow chains installed ( Y
page 74).
You can thereby allow the wheels to spin in a
controlled manner, achieving an increased driv-
ing force (cutting action). Tire pressure
Tire pressure specifications
Important safety notes
G WARNING
Underinflated or overinflated tires pose the
following risks: R
the tires may burst, especially as the load
and vehicle speed increase. R
the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction. R
the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel: R
monthly, at least R
if the load changes R
before beginning a long journey R
under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
The data on the Tire and Loading Information
placard and tire pressure table shown here are
examples. Tire pressure specifications are vehi-
cle-specific and may deviate from the data
shown here. The tire pressure specifications
that are valid for your vehicle can be found on
the Tire and Loading Information placard and
tire pressure table on the vehicle.
General notes The recommended tire pressures for the tires
mounted at the factory can be found on the
labels described here.

Fuel
Important safety notes
G WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before
refueling.
G WARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come
into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following: R
Wash away fuel from skin immediately
using soap and water. R
If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay. R

! Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition
if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system.
Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
