Standing waterPassenger compartment
Driving abroad
Abroad, there is an extensive
Mercedes-Benz service network at your
disposal. If you plan to drive into areas
which are not listed in the index of your
Mercedes-Benz Center directory, you
should request pertinent information from
an authorized Mercedes-Benz Center.Control and operation of radio
transmitter
COMAND*, radio, and telephone*
!Do not drive through flooded areas or water
of unknown depth. Before driving through water,
determine its depth. Never accelerate before
driving into water. The bow wave could force wa-
ter into the engine and auxiliary equipment, thus
damaging them.
If you must drive through standing water, drive
slowly to prevent water from entering the pas-
senger compartment or the engine compart-
ment. Water in these areas could cause damage
to electrical components or wiring of the engine
or transmission, or could result in water being in-
gested by the engine through the air intake,
causing severe internal engine damage. Any
such damage is not covered by the
Mercedes-Benz Limited Warranty.
Warning!G
Always fasten items being carried as
securely as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and cause injury
to vehicle occupants unless the items are
securely fastened in the vehicle.
The trunk is the preferred place to carry
objects.
Warning!G
Please do not forget that your primary re-
sponsibility is to drive the vehicle safely.
Only operate the COMAND*, radio or tele-
phone
1 if road, traffic and weather condi-
tions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
1Observe all legal requirements.

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).

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.
