Towing the vehicle
Towing the vehicle
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.
When circumstances do not permit the
recommended towing methods, the
vehicle may be towed with all wheels on
the ground or front axle raised only so far
as necessary to have the vehicle moved to
a safe location where the recommended
towing methods can be employed.
!Do not tow-start the vehicle.
!Use flatbed or wheel lift/dolly equipment
with SmartKey or SmartKey with KEYLESS-GO*
in starter switch turned to position0.
Do not tow with sling-type equipment. Towing
with sling-type equipment over bumpy roads will
damage radiator and supports.
Towing of the vehicle should only be done using
the properly installed towing eye bolt. Never at-
tach tow cable, tow rope, or tow rod, to vehicle
chassis, frame, or suspension parts.
Switch off the ESP
® (page 71), the tow-away
alarm (
page 78) and the automatic central
locking (
page 334).
Warning!G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run

there is a malfunction in the brake
system

there is a malfunction in the power
supply or in the vehicle’s electrical
system
as that will be necessary to adequately
control the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey or
SmartKey with KEYLESS-GO* is in starter
switch position 2.

Towing the vehicle
Warning!G
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.
!When towing the vehicle with all wheels on
the ground or with the front axle raised, the start-
er battery must be connected and charged. Oth-
erwise:

you will not be able to switch on the ignition

you will not be able to engage the automatic
transmission in positionN (
page 394)

you cannot release the electronic parking
brake
For information on charging the starter battery
see “Batteries” (
page 655) or see “Jump start-
ing” (
page 660).
!Make sure that the electronic parking brake
is released. If the electronic parking brake is
malfunctioning, release it mechanically
(
page 637).
!If the vehicle is towed with the front axle
raised, the automatic transmission must be in
positionN and the engine must be shut off
(SmartKey or SmartKey with KEYLESS-GO* in
starter switch position0 or1). Active braking
action through the ESP
® may otherwise
seriously damage the brake system.
!When towing the vehicle with all wheels on
the ground, the automatic transmission must be
shifted to positionN and the SmartKey or
SmartKey with KEYLESS-GO* must be in starter
switch position2.
When towing the vehicle with all wheels on the
ground or the front axle raised, the vehicle may
be towed only for distances up to 30 miles
(50 km) and at a speed not to exceed 30 mph
(50 km/h).
!If the vehicle is towed with all wheels on the
ground or with the front axle raised, the trans-
mission must be in positionN.
If you turn off the engine using

the SmartKey and

remove the SmartKey from the starter
switch
or

open a door

the KEYLESS-GO* start/stop button and
open a door
the transmission will shift to park position P
automatically.

Fuses
Fuses
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the component(s) and
systems secured by that fuse will stop op-
erating.
If a newly inserted fuse blows again, have
the cause determined and rectified by an
authorized Mercedes-Benz Center.
The following aids are available to help you
replace fuses. They are located in the trunk
with the vehicle tool kit (
page 632):

Fuse chart
The fuse chart explains the fuse alloca-
tion and fuse amperages.

Spare fuses

Special fuse extractor
The electrical fuses are located in different
fuse boxes:

in the dashboard on the passenger side
(
page 669)

in the dashboard on the driver’s side
(
page 669)

behind the rear center armrest
(
page 669)

on the driver’s side of the engine com-
partment (
page 668)

on the passenger side of the engine
compartment (
page 668)
Before replacing fuses:
Engage the electronic parking brake
(
page 384).
Make sure the automatic transmission
is set to P (
page 389).
The gear position indicator in the ta-
chometer display should be on P.
Turn off all electrical consumers.
Turn off the engine (page 387).
Switch off the vehicle’s internal electri-
cal functions (
page 658).
Warning!G
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 ap-
proved 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 (
page 658) when you are working on
the fuses.
iA blown fuse must be replaced by an appro-
priate 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.
