G
Warning!
Never charge a battery while still installed in
the vehicle unless the accessory battery
charge unit approved by Mercedes-Benz is
being used. Gases may escape during
charging and could cause an explosion that
may result

in personal injury, paint damage or
corrosion.
An accessory battery charge unit specially
adapted for Mercedes-Benz vehicles and
tested and approved by Mercedes-Benz is
available. It permits the charging of the
battery in its installed position. Contact an
authorized Mercedes-Benz Center for
information and availability.
Charge battery in accordance with the
separate instructions for the accessory
battery charger.
Have the battery charged at an authorized
Mercedes-Benz Center. If you charge the
battery yourself, follow the operating
instructions for your charging device.
Only use a battery charge unit with a
maximum charging voltage of 14.8 V.
X Charge battery in accordance with the
instructions of the battery charger
manufacturer. Jump starting
G
Warning!
Failure to follow these directions will cause
damage to the electronic components, and
can lead to a battery explosion and severe
injury or death. Never lean over batteries while connecting or
jump starting. You might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water, and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
Attempting
to

jump start a frozen battery can
result in it exploding, causing personal injury.
Read all instructions before proceeding.
! Do not tow-start the vehicle. You could
otherwise seriously damage the automatic
transmission which is not covered by the
Mercedes-Benz Limited Warranty.
! Jump starting should only be performed
using the jump-start terminals located in
the engine compartment.
Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using a
battery quick-charge unit.
If the engine does not run after several
unsuccessful starting attempts, have it
checked at the nearest authorized
Mercedes-Benz Center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter and may
present a fire risk.
Make sure the jumper cables do not have
loose or missing insulation.
Make sure the cable clamps do not touch
any other metal part while the other end is
still attached to a battery. Jump starting

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.

!
Vehicles without 4MATIC:
Because the ESC operates automatically,
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
Mercedes-Benz Limited Warranty.

SmartKey to be left in starter switch with
the ignition switched off. As soon as the
SmartKey is removed from the starter
switch the automatic transmission will shift
to park position P. Fuses
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
