519 Practical hints
Towing the vehicle
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 power
supply or in the vehicle’s electrical sys-
tem
Prior to towing the vehicle with all wheels on
the ground, make sure the starter switch is
in position2 (
page 40).
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.
i
To 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.
i
If the battery is disconnected or discharged,
the automatic transmission will remain locked in
positionP and the SmartKey will not turn in the
starter switch. For more information, see “Bat-
tery” (page 507) and “Jump starting”
(
page 515).
!
When towing the vehicle with all wheels on
the ground, note the following:
With the automatic central locking activated and
the ignition in position2 (
page 40), the vehicle
doors lock if the left front 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 126).
Towing of the vehicle should only be done using
the towing eye bolt. Never attach tow cable, tow
rope or tow rod to vehicle chassis, frame or sus-
pension parts.

522 Practical hintsFusesThe 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 469):


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 523)


Fuse box in cargo compartment
(page 523)


Fuse box in passenger compartment
(page 524)Before replacing fuses:

Apply parking brake (
page 65).

Make sure the automatic transmission
is set toP (
page 187).
The gear position indicator in the multi-
function display should be on
P.

Turn off all electrical consumers.

Turn off the engine (
page 40).

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.i
A 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-Light Truck Center will be glad to
advise you on this subject.

Emergency engine shut-down
If the engine cannot be turned off as de-
scribed in the “Getting started” section
(page 66), you may use the following
emergency procedure.

Take the fuse chart from the vehicle
tool kit (
page 470).
