421 Practical hints
Towing the vehicle
Towing the vehicle
Mercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment.
When circumstances do not permit the
recommended towing methods, the vehi-
cle may be towed with all wheels on the
ground or front wheels raised only so far as
necessary to have the vehicle moved to a
safe location where the recommended
towing methods can be employed.
!Vehicles with automatic transmission*: Do
not tow-start vehicle.
!Use flatbed or wheel lift/dolly equipment
with the SmartKey in the starter switch in
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 tow-away alarm (
page 91) and
the automatic central locking (
page 102).
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 is in
starter switch position2.
If the SmartKey is left in starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock,
remove SmartKey from starter switch and
reinsert.
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.
!If the vehicle is towed with the front axle
raised, the gear selector lever* must be in
positionN (manual transmission: gear shift lever
in neutral position) and the engine must be shut
off (SmartKey in starter switch position0or1).
Active braking action through the ESP
® may
otherwise seriously damage the brake system.
When towing the vehicle with all wheels on the
ground, the gear selector lever* must be in
positionN (manual transmission: gear shift lever
in neutral position) and the SmartKey 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).

Towing the vehicle
Installing towing eye bolt
The towing eye bolt is supplied with the ve-
hicle tool kit, located in the compartment
underneath the trunk floor (
page 382).
The towing eyes are located on the passen-
ger side in the front and rear bumper.

(
page 382).
Front cover
1Cover in front bumper
!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, please note the following:
With the automatic central locking activated and
the SmartKey in starter switch position2, the
vehicle doors lock if the left front wheel as well
as the right rear wheel are turning at vehicle
speeds of approximately 9 mph (15 km/h) or
more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking
(
page 102).
iTo signal turns while being towed with the
hazard warning flasher in use, switch on ignition
and activate the combination switch for the left
or right turn signal in the usual manner – only the
selected turn signal will operate.
Upon canceling the turn signal, the hazard warn-
ing flasher will operate again.
iThe gear selector lever* will remain locked
in positionP (vehicles with automatic transmis-
sion*) and the SmartKey will not turn in the
starter switch if the battery is disconnected or
discharged. For more information, see “Battery”
(
page 415) or “Jump starting” (page 419).

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 by an
authorized Mercedes-Benz Center.
The following aids are available to help you
replace fuses. The spare fuses and the fuse
extractor are located in the trunk with the
vehicle tool kit (
page 382) and the fuse
chart is located in the fuse box in the
passenger compartment (
page 425).

Fuse chart
The fuse chart explains the fuse
allocation and fuse amperages.

Spare fuses

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

in the passenger compartment on the
driver’s side (
page 425)

on the driver’s side of the engine
compartment (
page 426)Before replacing fuses:
Apply the parking brake (page 59).
Make sure the gear selector lever* is
set to positionP (
page 157) (manual
transmission to Neutral).

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 by an
authorized Mercedes-Benz 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-Benz Center will be glad to advise
you on this subject.
