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 malfunc-
tion of the vehicle’s electronic system, pos-
sibly 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.
G
Warning!
Please do not forget that your primary
responsibility is to drive the vehicle. A
driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we
recommend that you pull over to a safe
location and stop before placing or taking
a telephone call.
If you choose to use the telephone
17
while
driving, please use the hands-free device
and only use the telephone when road,
weather and traffic conditions permit.
Some jurisdictions prohibit the driver from
using a mobile telephone while driving a
vehicle.
Only operate the audio system or
COMAND
17
(Cockpit Management and
Data System) if road, weather and traffic
conditions 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 (approxi-
mately 14 m) every second.
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 author-
ized technicians.
Engine adjustments should not be altered in
any way. Moreover, the specified service pro-
cedures must be carried out regularly accord-
ing to Mercedes-Benz servicing require-
ments. For details refer to the Maintenance
Booklet.
G
Warning!
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains car-
bon 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 driv-
ing, have the cause determined and cor-
rected immediately. If you must drive under
these conditions, drive only with at least
one window fully open at all times.
