Driving instructions
264
Only operate the audio system or
COMAND
18
(Cockpit Management and
Data System) if road, weather and traffic
conditions permit. Otherwise, you may not
be able to observe traffic conditions and
could endanger yourself and others.
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.
Telephones and two-way radios
G
Warning!
Never operate radio transmitters equipped
with a built-in or attached antenna, such as
a portable telephone or a citizens band unit,
from inside the vehicle while the engine is
running. Doing so could lead to a
malfunction of the vehicle’s electronic
system, possibly resulting in an accident
and/or serious personal injury. Radio
transmitters should only be used inside the
vehicle if they are connected to an antenna
that is installed on the outside of the
vehicle.
Refer to the radio transmitter operation
instructions regarding use of an external
antenna.
Emission control
Certain systems of the engine serve to keep
the toxic components of the exhaust gases
within permissible limits required by law.
These systems will function properly only
when maintained strictly according to factory
specifications. Any adjustments on the
engine should, therefore, be carried out only
by qualified Mercedes-Benz Center
authorized technicians.
Engine adjustments should not be altered in
any way. Moreover, the specified service
procedures must be carried out regularly
according to Mercedes-Benz servicing
requirements. For details refer to the
Maintenance Booklet.
G
Warning!
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains
carbon monoxide (CO), and inhaling it can
cause unconsciousness and possible
death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while
driving, have the cause determined and
corrected immediately. If you must drive
under these conditions, drive only with at
least one window fully open at all times.
18 Observe all legal requirements.
