Have any passenger exit the vehicle at
a safe distance from the roadway.
Warning!
G
The dimensions of the spare wheel
(Minispare wheel or collapsible tire) are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel
mounted. Adapt your driving style accord-
ingly.
The spare wheel is for temporary use only.
When driving with a spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed a vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Light
Truck Center as soon as possible to have the
spare wheel replaced with a regular road
wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP
® when a
Minispare wheel is mounted.
Warning!
G
Vehicles with air suspension package*:
Do not open or close any doors or the
tailgate while mounting a spare wheel. The
vehicle could rise or lower to a previously
selected level. You or others could be
injured as a result.
i
Open door only when conditions are safe to
do so.

Step 1 (Disconnecting)

Set the automatic transmission to
positionP (
page 187).

Firmly depress the parking brake
(page 65).

Turn off the engine (
page 66).

Leave the ignition switched on
(page 40).
!
Never loosen or detach battery terminal
clamps while the engine is running or the
SmartKey is in the starter switch. Otherwise the
alternator and other electronic components
could be severely damaged.
Have the battery checked regularly by an
authorized Mercedes-Benz Light Truck Center.
Contact your authorized Mercedes-Benz Light
Truck Center for further information.
Warning!
G
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof battery only to avoid the risk
of acid burns in the event of an accident.
Warning!
G
Disconnecting, removing, reinstalling and
reconnecting the battery is a complicated
and technically demanding procedure that
also requires safety precautions to avoid the
risk of injury. We strongly recommend that it
be performed by a qualified technician or an
authorized Mercedes-Benz Light Truck
Center only. Please read the instructions
fully before beginning operation and only
undertake it if you feel fully capable of
performing all of the tasks involved as de-
scribed in these instructions. Observe all
safety instructions and precautions when
handling automotive batteries
(page 507). Performing the tasks involved
incorrectly can cause damage to the vehicle
and impair the operating safety of the
vehicle, and/or cause severe injury to you
or others.
i
With a disconnected battery you will no
longer be able to turn the SmartKey in the starter
switch and pressing the KEYLESS-GO*
start/stop button will have no effect.
i
If your battery is discharged, the vehicle
must be jump started (
page 515) using the
jump start contacts in the engine compartment,
or an accessory battery charge unit* approved
by Mercedes-Benz must be connected using the
jump start contacts in the engine compartment
(see separate instructions for the accessory bat-
tery charge unit*) before any of the following
steps can be performed. If the battery cannot be
jumped or charged, please contact an
authorized Mercedes-Benz Light Truck Center.

518 Practical hintsTowing the vehicleMercedes-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 only so far as necessary to have
the vehicle moved to a safe location where
the recommended towing methods can be
employed.!
Use flatbed or wheel lift/dolly equipment,
with the SmartKey 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.
To prevent damage during transport, do not tie
down vehicle by its chassis or suspension parts.
Use the towing eyes.
Switch off the ESP
® (page 99) and the auto-
matic central locking (page 126).
!
Do not tow-start the vehicle.
!
Do not tow with one axle raised. Doing so
could damage the transfer case, which is not
covered by the Mercedes-Benz Limited
Warranty.
All wheels must be on or off the ground. Observe
instructions for towing the vehicle with all
wheels on the ground.
!
When towing the vehicle with all wheels on
the ground, the automatic transmission must be
in positionN and the starter switch must be in
position2 (
page 40).
When towing the vehicle with all wheels on the
ground, 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).
Keep in mind that it is important for the
SmartKey to be in the respective starter switch
positions as described above. As soon as the
SmartKey is removed from the starter switch or
the SmartKey with KEYLESS-GO* is removed
from the vehicle, the automatic transmission will
shift to park positionP see “Starter switch posi-
tions” (
page 39).

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.
