Safety notes
G
Warning!
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate the HOLD function or DISTRONIC
PLUS if the vehicle is to be towed.
Mercedes-Benz recommends

that the vehicle
be transported with all wheels off the ground
using flatbed or appropriate wheel lift/dolly
equipment. This method is preferable to other
types of towing.
! To prevent damage during transport, do
not tie down vehicle by its chassis or
suspension parts.
If circumstances do not permit the
recommended towing methods, the vehicle
may be towed with all wheels on the ground or front axle raised (except vehicles with
4MATIC) only

so far as necessary to have the
vehicle moved to a safe location where the
recommended towing methods can be
employed.
! Before towing the vehicle observe the
following instructions:
R Do not tow-start the vehicle. You could
otherwise seriously damage the
automatic transmission which is not
covered by the Mercedes-Benz Limited
Warranty.
R Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
R Towing of the vehicle should only be
done using the properly installed towing
eye bolt. Never attach a tow cable, tow
rope or tow rod to the vehicle chassis,
frame or suspension parts. G
Warning!
With the engine not running, there is no power
assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
! Avoid pulling the vehicle abruptly or
diagonally, since it could result in damage
to the chassis alignment.
! Do not use the towing eye bolt for
recovery, as

this could damage the vehicle.
If in doubt, recover the vehicle with a crane.

the engine and ignition must be shut off
(SmartKey in starter switch position 0 or
1 or KEYLESS-GO start/stop button in
position 0 or 1) when the vehicle is being
towed with one axle raised.
Active braking action through the ESC may
otherwise seriously damage the brake
system which is not covered by the

Introduction
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and
systems secured by that fuse will stop
operating. G
Warning!
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system in
question and do not attempt to repair or
bridge a blown fuse. Using other than
approved fuses or using repaired or bridged
fuses may cause an overload leading to a fire,
and/or cause damage to electrical
components and/or systems. Have the cause
determined and remedied by an authorized
Mercedes-Benz Center.
! Switch off the vehicle’s internal electrical
functions when you are working on the
fuses.
A blown fuse must be replaced by an
appropriate spare fuse (recognizable by its
color or the fuse rating given on the fuse) of the amperage recommended in the fuse
chart. Any Mercedes-Benz Center will be glad
to advise you on this subject.
i
In case of a blown fuse contact Roadside
Assistance or an authorized Mercedes-
Benz Center.
If a newly inserted fuse blows again, have the
cause determined and rectified by an
authorized Mercedes-Benz Center.
The fuse chart is located in the trunk with the
vehicle tool kit (Y page 412). The fuse chart
explains the fuse allocation and fuse
amperages. Before replacing fuses
X Engage the electronic parking brake.
X Make sure the automatic transmission is in
park position P.
The transmission position indicator in the
multifunction display should be on P.
X Switch off all electrical consumers.
X Turn off the engine. Fuse box in passenger compartment
