541 Practical hints
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:
The automatic transmission must be in
positionN (
page 193).
The starter switch must be in position2
(
page 41).
Keep in mind that it is important that the
starter switch is in position2. As soon as the
SmartKey is removed from the starter
switch or the engine is turned off with
KEYLESS-GO* and you open the driver’s
door or the front passenger door, the auto-
matic transmission will shift to park
positionP, see “Starter switch positions”
(
page 41).
The battery must be connected and charged.
Otherwise, the starter switch cannot be set
to position2 and the automatic transmission
will remain locked in positionP.
!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.
iWhen towing the vehicle with all wheels on
the ground, note the following:
With the automatic central locking activated and
the starter switch in position2 (
page 41), the
vehicle doors lock if a wheel is turning at a speed
of approximately 9 mph (15 km/h) or above.
To prevent the vehicle doors from locking,
deactivate the automatic central locking
(
page 130).
iTo signal turns while being towed with
hazard warning flasher in use, set the starter
switch to position2 and activate combination
switch for left or right turn signal in usual manner
– only the selected turn signal will operate.
Upon canceling the turn signal, the hazard
warning flasher will operate again.

Fuses
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and sys-
tems secured by that fuse will stop operat-
ing.If a newly inserted fuse blows again, have
the cause determined and rectified by an
authorized Mercedes-Benz Light Truck
Center.
The following aids are available to help you
replace fuses. They are included with the
vehicle tool kit (
page 495):
Fuse chart
The fuse chart explains the fuse alloca-
tion and fuse amperages.
Spare fuses
Fuse extractor
The electrical fuses are located in different
fuse boxes:
Fuse box in engine compartment
(
page 545)
Fuse box in cargo compartment
(
page 545)
Fuse box in passenger compartment
(
page 546)Before replacing fuses:
Apply parking brake (page 68).
Make sure the automatic transmission
is set toP (
page 194).
The gear position indicator in the multi-
function display should be on
P.
Turn off all electrical consumers.
Turn off the engine (page 41).
Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*:
Open the driver’s door (this puts
the starter switch in position0,
same as with the SmartKey re-
moved from the starter switch). The
driver’s door then can be closed
again.
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 au-
thorized Mercedes-Benz Light Truck Center.
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 Light Truck Center will be glad to
advise you on this subject.
