408 Practical hintsTowing the vehicleWarning!
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 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, 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.
Switch off the tow-away alarm
(page 87).
To prevent the vehicle doors from lock-
ing, deactivate the automatic central
locking (
page 148).
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 vehicle chassis,
frame or suspension parts.
iIf the battery is disconnected or dis-
charged

the SmartKey will not turn in the
starter switch. For more informa-
tion, see “Battery” (
page 401)
and “Jump starting” (page 404).


the gear selector lever will remain
locked in position P. For informa-
tion on manually unlocking trans-
mission gear selector lever, see
(page 380).

410 Practical hintsFusesThe electrical fuses in your vehicle serve to
stop the supply of electricity to a device
that is malfunctioning. This helps to
prevent damage to the other vehicle
electronics.
The following aids are available to help you
change fuses.

Fuse chart


Spare fuses


Fuse extractorThe electrical fuses are located in different
fuse boxes.


Main fuse box in passenger compart-
ment (
page 411)


Fuse box in engine compartment
(page 411)


Fuse box in trunk (
page 412)
Aids for changing fuses
Fuse chart
The fuse chart is found in the main fuse
box in the passenger compartment
(page 411). The amperages of the fuses
are also given there.
Spare fuses
Spare fuses are found in the vehicle tool kit
in the spare wheel well (
page 373).
Fuse extractor
The fuse extractor is found in the fuse box
cover in the trunk (
page 412).
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
rating.
Otherwise, electrical parts or systems
could be damaged.
Never attempt to repair or bridge a
blown fuse. Have the cause determined
and remedied by an authorized
Mercedes-Benz Center.

Technical data
Fuels, coolants, lubricants, etc.
Flexible Fuel Vehicles
Flexible Fuel Vehicles are identified by a
label reading
Premium gasoline or E85
only! on fuel filler flap).
These vehicles are designed to operate on
premium unleaded gasoline or Ethanol fuel
(E85), or on any mixture of these two.
Ethanol fuel (E85) is a mixture of approxi-
mately 85% Ethanol and 15% unleaded
gasoline. Switching fuels
For best performance and driveability it is
recommended to use either one or the oth-
er fuel. A refueling pattern that alternates
between the two different fuels should be
avoided if possible.
When switching fuels, make sure:


Fuel level is below half full.


Fuel level is above reserve (reserve
warning lamp is not lit).


Amount of added fuel is more than
5 gallons (20 liters).


Ignition is off during refill.


Immediately after refueling engine is
started and operated for at least five
minutes.
These precautions and recommendations
are supposed to prevent any difficulties
when starting and operating the engine
which otherwise may be experienced
before the engine has fully adapted to the
different fuel. If in spite of these recommendations the
engine does not perform properly, adding
more gasoline (at least 3 gallons
[12 liters]) to the fuel may improve the
engine behavior.
Cold weather performance
It is possible that starting times will signif-
icantly increase at temperatures below
32°F (0°C). At low temperatures the use
of a block heater is recommended (see an
authorized Mercedes-Benz Center for
further information). Rough idling may also
be experienced at such temperatures
before the engine is fully warmed up.
Warning!
G
Ethanol fuel (E85) and its fumes are highly
flammable, poisonous and burn easily. Etha-
nol fuel can cause serious injuries if ignited
or if you come into contact with it or inhale
fumes of it. Avoid inhalation of Ethanol
fumes and skin contact with Ethanol. Extin-
guish all open flames before fueling. Never
smoke or create sparks close to Ethanol.
!E85 fuel is unsuitable for use when am-
bient temperatures fall below 14°F
(-10°C).

Technical data
Fuels, coolants, lubricants, etc.
Windshield washer system and headlamp cleaning system
Both the windshield and headlamp washer
systems are supplied from the windshield
washer fluid reservoir.
The washer fluid reservoir has a capacity of
approximately

6.4 US qt (6.0 l) in vehicles with head-
lamp cleaning system*


3.2 US qt (3.0 l) in vehicles without
headlamp cleaning system

Refill the reservoir with MB Windshield
Washer Concentrate and water (or con-
centrate and commercially available
premixed windshield washer sol-
vent/antifreeze, depending on ambient
temperatures).
Windshield and headlamp washer fluid
mixing ratio
For temperatures above freezing point, use
MB Windshield Washer Concentrate “S”
and water:


1 part “S” to 100 parts water
[40 ml “S” to 1 gallon (4 liters) water]
For temperatures below freezing point, use
MB Windshield Washer Concentrate “S”
and commercially available premixed
windshield washer solvent/antifreeze:


1 part “S” to 100 parts solvent
[40 ml “S” to 1 gallon (4 liters) solvent].
Warning!
G
Washer solvent/antifreeze is highly flamma-
ble. Do not spill washer solvent/antifreeze
on hot engine parts, because it may ignite
and burn. You can be seriously burned.
