400 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.
!Towing of the vehicle should only be done
using the towing eye. Never attach tow cable,
tow rope or tow rod to 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 SmartKey in starter switch position 2, the
vehicle doors lock if a wheel is turning at vehicle
speeds of approximately 9 mph (15 km/h) or
above.
To prevent the vehicle doors from locking,
deactivate the automatic central locking
(
page 155).
iTo signal turns while being towed with
hazard warning flasher in use, turn the SmartKey
in starter switch to position 2 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.
iThe gear selector lever will remain locked in
park position P and the SmartKey will not turn in
the starter switch if the battery is disconnected
or discharged. For more information, see “Bat-
tery” (
page 394) and “Jump starting”
(
page 397).
For information on manua lly unlocking the gear
selector lever, see (
page 371).

Practical hints
Fuses
 Fuses
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. If a newly inserted fuse blows again, have
the cause determined and rectified at an
authorized Mercedes-Benz Light Truck
Center.
The following aids are available to help you
replace fuses.

Fuse chart
The fuse chart explains the fuse
allocation and fuse amperages.
The fuse chart is located in the main
fuse box in the passenger compart-
ment (
page 404).

Spare fuses
The spare fuses are located in the main
fuse box in the passenger compart-
ment (
page 404).

Fuse extractor
The fuse extractor is located in the
vehicle tool kit in the rear footwell
(
page 364).The electrical fuses are located in different
fuse boxes:

in the passenger compartment on the
driver’s side (
page 404)

in the front passenger footwell
(
page 404)

in the middle tunnel (page 405)

in the battery box (page 406)
Before replacing fuses:
Apply parking brake (page 62).
Make sure the gear selector lever is set
to park position P (
page 162).
Turn off all electrical consumers.
Turn off the engine (page 64).
Remove the SmartKey from the starter
switch.
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
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 at an
authorized Mercedes-Benz Light Truck
Center.
iA 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-Light Truck Center will be glad to
advise you on this subject.
