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

!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.
