410 Practical hintsTowing the vehicleWarning!
G
The brake system requires electrical power
to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. To brake, the driver
must then apply significantly greater brake
pedal pressure and depress the pedal much
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the
brake pedal. Brakes are only applied to the
front wheels. Stopping distance is in-
creased! Adapt your driving style according-
ly. For more information, see “SBC brake
system” (
page 85).
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 ve-
hicle. Adapt your driving accordingly.
!When towing the vehicle with all wheels
on the ground, please note the follow-
ing:
With the automatic central locking acti-
vated and the SmartKey in starter
switch position2, or KEYLESS-GO*
start/stop button in position2, the ve-
hicle doors lock if the left front wheel
as well as the right rear wheel are turn-
ing at vehicle speeds of approx. 9 mph
(15 km / h) or more.
To prevent the vehicle door locks from
locking, deactivate the automatic cen-
tral locking (
page 110).
Towing of the vehicle should only be
done using the properly installed tow-
ing eye bolt. Never attach tow cable,
tow rope or tow rod to the vehicle chas-
sis, frame or suspension parts.
iIf the battery is disconnected or dis-
charged
the SmartKey will not turn in the
starter switch
the gear selector lever will remain
locked in positionP.
For more information, see “Batteries”
(
page 401) and
“Jump starting” (
page 406).
412 Practical hintsFusesThe fuses in your vehicle serve to interrupt
the power supply to electrical device that
are malfunctioning. This helps to prevent
damage to other vehicle electronics.
The following aids are available to help you
replace fuses. They are located in the trunk
with the vehicle tool kit (
page 372).

The fuse chart explains the fuse alloca-
tion and fuse amperages.
Spare fuses
Fuse extractor
Main fuse box
The main fuse box is located in the engine
compartment on the driver’s side in front
of the bulkhead (wall separating the engine

Warning
G
Only use fuses approved for Mercedes-Benz
with the specified amperage for the system
in question. Otherwise, a short circuit could
result and cause a fire.
!Only install fuses that have been tested
and approved by Mercedes-Benz and
that have the specified amperage rat-
ing.
Otherwise, electrical parts or compo-
nents could be damaged.
Never attempt to repair or bridge a
blown fuse. Have the cause determined
and remedied by an authorized
Mercedes-Benz Center.
